The Corpse That Wasn't There

"It's me, Kaiba. And this time, you don't stand a *ghost* of a chance."

"Yu-Gi-Oh!"  

So I met Norizuki twice in my life, and the first time something funny happened (though Norizuki probably didn't realize it), though the Mephisto editor-in-chief sure did and he was a huge help to me...

Norizuki Rintarou's series about the adventures of the fictional writer/amateur detective Norizuki Rintarou and his father Inspector Norizuki finally gets a new volume later this month in the form of Norizuki Rintarou no Fukaku, which also has the English title The Unawareness of Norizuki Rintarou on the cover. The contents of the four-story-volume was recently announced and it turns out I already read half of the stories included. While the final story is an original tale written especially for the volume, I have already reviewed the first two stories in the book: Higisha Shibou ni Yori ("Due to the Death of the Suspect") and Shinritekikashi Ari ("Stigmatized Property") were both originally written as part of guess-the-culprit anthology projects, where the first part of the story would be published and then readers would have time to write in their solutions, before the second half of the story would be published. I read these stories when the volumes collecting these stories were published and enjoyed both of them as fair-play stories where we get to see Norizuki's logic-based puzzles in their full glory. 

The title of the third story included in the volume Norizuki Rintarou no Fukaku however didn't sound familiar to me at first, until I looked it up and learned I actually had the story already in my possession. The story had been written as part of an anthology project running in the magazine Mephisto titled The Finishing Stroke, fousing on stories with final lines that turn things around. I think I did know Norizuki had written something for this anthology project, but I hadn't quite realized it had in fact been a story starring Rintarou. While there's a dedicated The Finishing Stroke book release, which collects this story too among others, I happen to have the Mephisto issue where Norizuki's Tsugi wa Anta no Ban da yo ("You're Next!") was originally published, so I decided to read it (I am not aware of any (major) differences between the original publication and the collected version).

Pater Norizuki is investigating a rather kooky case and as always, he ends up discussing the case with filius Rintarou to see if the writer has some ideas. Komiyama Michiyo, an elderly, wealthy woman was found murdered in her own home: the woman ran several succesful businesses and was always staying in hotels during weekdays for all her business obligations, though she made it a rule to return home for the weekend: she was discovered dead on a Monday. While at first it seems like a robbery ending in death, the fact the murderer actually managed to switch off the security cameras and evade all the cameras in the neigborhood seems to suggest the "thief" had very detailed knowledge about the victim's house, its security measures and thus would have known the busy woman was seldom at home during the week: so why would a genuine thief would have picked the weekend, when the woman was always at home? This alone would just make for an ordinary case, but things took a weird turn when Suzumura Shigeki, an office employee who has made it a habit to jog in the evening after work, made a report about having found the body of a dead woman in the park he always visits: an elderly woman had died recently there due to dehydration, and it was at that same spot he saw an elderly woman collapsed on the ground. At first he thought it was another case of dehydration and tried to wake the woman up, but she was clearly dead and her arms had been tied with zip ties, indicating a crime. As he was out jogging, he didn't have his phone with him and had to report from the nearest public phone. When he and a patrolman returned to the park however, they found no trace of the woman, though it was clear someone had been lying at the place Suzumura saw the body. When he described the face of the woman however, it turned out to be the face of...Komiyama Michiyo, a woman who was already dead by then!

The spooky story reminds in a way of the classic, award-winning An Urban Legend Puzzle in this same series and indeed, while this story does not feature an actual, well-known urban legend/ghost story, the story does start as a genuine scary story, told as the experience of an "unnamed" office worker (Suzumura) who dreams of jogging at night and then running into a ghostly face of a woman and later, Suzumura testifies he'd been seeing that woman in his dreams long before he stumbled the dead body in the park. But ghosts and prophetic dreams can't be real....right? Of course, this is an experiment in logical deduction as are all of the Rintarou short stories and indeed, Rintarou does offer a very logical solution to what happened. As many of the Rintarou stories go (especially those with Rintarou and his father just discussing a case as armchair detectives), the story's cleverness lies in how the story is presented to the reader in terms of how every element is connected, and Rintarou then using clever questions to steer the reader (and his father) towards a subversion of the original presentation, showing how everything had been connected in a different manner in reality. This is also executed satisfactorily in this tale, and while some elements do feel a bit too familiar if you've read a healthy amount of the Rintarou short stories, Tsugi wa Anta no Ban da yo is a pretty solid entry in the series.

It's not a very long story, so there's not much more I can talk about without giving away too much. Looking at the already available three stories that will be included in the upcoming Norizuki Rintarou no Fukaku volume though, I think these were all really solid short mystery tales, with of course the first two being pure guess-the-culprit puzzles seperated in a "problem" and "solution" part, while Tsugi wa Anta no Ban da yo is a bit more open, but feels more unique with its ghost story set-up . I do have to admit that now that I have read three of the four stories, it's likely I won't be picking up a copy of Norizuki Rintarou no Fukaku right away on release just to read that one final original story.. Oh well, I'm sure I'll get to it eventually.

The Problem of the Red Rose

"There's the scarlet thread of murder running through the colourless skein of life, and our duty is to unravel it, and isolate it, and expose every inch of it."

"A Study in Scarlet" 

Unsurprisingly, I have quite a few mystery books that have red as the main color on the cover. I wonder what color is the rarest though. Something like purple?

Terada Satoshi is a young detective assigned to the prestigious homicide division of the Metropolitan Police Department with a bright future awaiting him.... until he foolishly left confidential files at the house of a suspect during a house search. The woman living with the suspect posted the files online, making a laughing stock of the police, questioning their capabilities of actually conducting a criminal investigation. Terada wasn't a scapegoat, but the actual person who made the grave mistake of course, so he was severely punished for the deed: he was removed from the homicide division and effectively demoted by his assignment to the Red Museum. Following the example of the Black Museum of Scotland Yard, the MPD has its own Red Museum, where files and evidence concerning cases of which the statute of limitations have already passed are stored in the archives beneath the old brick mansion in Mitaka, Tokyo. His pride couldn't have been hurt worse, as gone are the days of investigating serious crimes, and left are just boxes filled with old evidence waiting for Terada to stick a nice label with a QR code on them so they can be registered into a database. The same old, day after day after day. 

The Red Museum is headed by Hiiro Saeko, an attractive woman but rather emotionally detached, and often referred to as the Snow Woman. Hiiro's rank is superintendent and she's supposed to be in the elite 'career path' within the police, so Terada suspects she must have really messed up too in the past to be stuck here despite her career history, staring at dead cases all day. However, soon after Terada's assignment to the Red Museum, Hiiro orders Terada to look into an old unsolved case they are registering into the database. Once he reports his findings to her, Hiiro manages to solve the case and identify the culprit decades after the murder happened! It turns out that while the Red Museum is storing away old cases, Hiiro doesn't consider all cases dead, and she goes over every case they register, solved or not, to see if she can uncover the real truth. In Ooyama Seiichirou's short story collection Akai Hakubutsukan ("The Red Museum", 2015), we follow Hiiro and Terada as they tackle five cases from the past... and the present.

In 2016, Akai Hakubutsukan had a live-action adaptation, which I reviewed back then. It was a feature-length special, adaptating multiple stories and in the end, I wasn't too impressed because it felt a bit chaotic. But on the other hand, I am a huge fan of Ooyama Seiichirou, which is partially connected to the fact I love short mystery stories, and Ooyama's a master in that form. As I have read most of Ooyama's work already (yes, I know I haven't written the review for the second Watson-ryoku yet...), it was just a matter of time I would get started on the Red Museum series. Actually, besides the television special, I had actually already read one of the stories collected in this first volume of the series, but for some reason it appears I never reviewed it, as I can't find a review of it on my blog. But as the third volume of the series released a few months ago, I knew it was time to finally get properly started on this series.

Pan no Minoshirokin ("Ransom for Bread") is the opening story. It was originally titled Akai Hakubutsukan ("The Red Museum") and is also about twice as long as all the other stories, so it was basically a pilot which was later extended into a full series. As such, it spends relatively much time explaining how Terada came to work at the Red Museum, his first impressions of the cold head of the museum, his meeting with the two other staff members of the museum and portraying Terada as someone who really is proud of having been in the homicide division, looking down at Hiiro as someone who probably has never conducted any real investigation herself and only being in a managerial role. Things of course change with this first case. Terada is sent to transfer evidence from the Shinagawa Police Station to the Red Museum for filing: the evidence is from a case that occured in 1999, when the director of the big bread supplier Nakajima Bread was murdered. Someone had been tampering with products of the company, introducing nails into the bread, which of course led to a huge drop in sales. The blackmailer then sent a letter to the director, demanding for a fortune if he wanted it to stop. The director was to bring the money in a suitcase by car, and he'd be contacted via his phone installed in his car. The police was of course not to be involved, but they were secretly informed and a police detective was hiding in the car's trunk, which allowed him to communicate with the director and maintain radio contact with the supporting detectives. The director was led to an abandoned manor in the forest. When he didn't appear after a while, the detective in the trunk sent supporting detectives in the house as he too entered the building, but they only found the suitcase with money in the house, and the director gone. While they did find an underground passage leading away from the house, they couldn't understand why the money had been left behind. Later, the director's dead body was found elsewhere, making this a murder case. The police soon suspected the ransom money had just been a ruse, an excuse to camouflage the real goal of murdering the director, but the person with the best motive for doing so had an iron-clad alibi and the case was left unsolved.

For some reason I thought this had been adapted as part of the first television adaptation, but I guess they only did the introductionary part and not the actual mystery. Which is a shame, as this is a great opening story. In a way, it reminds me a lot of the short story Y no Yuukai ("The Kidnapping of Y"), the last story in Ooyama's debut book Alphabet Puzzlers. It too deals with a case set in the past, an abduction case (a child in Y no Yuukai, the director who disappears from the house in this story), someone is ordered to drive around in a car as they are directed to deliver ransom money and the money ending up not being retrieved by the culprit, leading to speculations to their real goal. The mechanics behind the case and the way they are solved are completley different though. Pan no Minoshirokin cleverly disguises the main driving dynamics of its plot as a different kind of mystery, hiding the true solution behind a well-designed veil of deceit. Once you recognize the mystery for what it really is, everything falls nicely in place, showing the tight plotting Ooyama is known for. If there's one thing I would fault the story for, it's that it doesn't make as clever use of the series' premise as some of the other stories in the same collection: while the conclusion might feel more impactful because the story took place ago in the past, a lot of how the main mystery would've been solved, would have been the same whether the story had been told real-time (i.e. in 1999) or as it is now, as an account of something that happed long ago. I feel other stories, like the second and the last one in this volume, utilize the concept of these all being old cases to better effect.

Fukushuu Nikki ("Diary of Revenge") is Ooyama's take on a device seen in both Nicholas Blake's The Beast Must Die and Norizuki Rintarou's Yoriko no Tame ni ("For Yoriko"), being about the diary of someone planning to commit murder out of revenge. In fact, these three stories, written by different people at different times, form a kind of series: the diary of Yoriko no Tame ni starts the day after the diary in The Beast Must Die ends, and Fukushuu Nikki´s diary starts after Yoriko no Tame ni's diary ends! The diary in question is of Takami Kyouichi, a student who vows revenge for the death of his ex-girlfriend Maiko. The two had broken up some months ago, but one day, he suddenly got a call from Maiko who wanted to see him. When he went to her place, her body was found lying in the garden outside of her apartment building, having apparently leapt to her death from her balcony, but Kyouchi suspects there's more behind her death and based on evidence found in her apartment and the fact she had been pregnant when she died, he theorizes Maiko had been murdered by her current boyfriend, who wanted to get rid of her and the baby the easy way. Kyouichi feverishly starts to look for clues to identify this boyfriend so he can kill him, detailing his thinking process in his diary. After he managed to execute his plan, his diary was removed during a burglary in his apartment building and the diary was sent to the police, who of course wanted to have a talk with him: he died in a car crash while running away. 

Both Terada and Hiiro read through the diary, which seems like an open-and-shut case as the murderer confessed to every detail, from motive to how he planned the murder, in his diary, but to Terada's surprise, Hiiro seems dubious about the "truth" behind this case, as she notes a few strange discrepancies within the diary's account. The result is an excellently plotted tale of mystery, where Ooyama managed to plant so many clues and foreshadowing in a surprisingly short diary: the diary hides an intricately designed plot that, despite the diary's short length, allows for clever red herrings, multiple solutions and a neat conclusion to it all. I actually recently did go through The Beast Must Die in anticipation of this story, but I liked the clewing in this story so much better and the way the plot is constructed so much better, being much closer to the type of mystery I like (Ellery Queen-like plotting).  

Shi ga Kyouhansha wo Wakatsu made ("Till Death Do The Conspirators Part") is about a murder exchange, a trope very dear to Norizuki Rintarou, so these two stories do make it feel like Ooyama had him in mind while working on this book. Terada is out driving when he becomes witness to a tragic incident involving a truck hitting a car. The lone driver of the car is hit fatally, but in his dying words, he makes a confession to Terada. Twenty-five years ago, he was involved in a murder exchange: he wanted to kill somebody, but he'd become the main suspect, so he swapped his murder with someone else, allowing both of them to obtain perfect alibis for 'their' murders. While the man manages to explain they committed the murders one week after another, Terada unfortunately couldn't make out the names the dying man was trying to convey and by the time the emergency services arrived, the man had already passed away. The man is easily identified by his wife and his driver's license and so Terada and Hiiro start looking into a death that occurred twenty-five years ago in his circle, for which he would've been a suspect if not for a perfect alibi. They learn his wealthy uncle had been murdered, supporting the claim of the murder exchange and leading to the next question: who killed the uncle and who was the person they ordered a hit on?

This was the main plot of the (first) live-action special, but whereas I remember nothing about the plot from the special, I think it is a great story here. The story certainly starts out in an open manner: you know there have been two murders twenty-five years ago, one being on the rich uncle, but Terada's investigations into murders in the same time window lead to two possible candidates, where someone was murdered and there had been an obvious suspect in the possession of a perfect alibi. Here the fact this series is about cases set long in the past helps develop the mystery, as what makes this mystery hard to solve is the fact you can hardly expect someone to remember what they did on a certain day at a certain time twenty-five years ago, and how are you going to prove that? So it's neigh impossible to prove either of those suspects committed the uncle murder, and yet... Hiiro is not the type to give up easily and despite these setbacks, she boldly proposes a theory that proves with whom the traffic accident victim swapped his murders and how the other murder was committed. At this point of the series, Terada is still hoping he can one day return to the homicide division and as he was the one to hear the dying man's last words, he also wants to show Hiiro he's a better investigator than she'll ever be due to his hands-on experience, but of course, we all know who's better at this...

Honoo ("Flames") is a relatively short story and the one I know I had read before, but for some reason I never wrote a review for it. Hiiro draws Terada's attention to an essay written by a photographer, whose family died in a fire: when she was in elementary school, she had gone off on a school trip, only to return an orphan. It was only later she heard the horrible truth: her aunt (sister of her mother) was going to stay at their home for a day because she and her boyfriend had a horrible breakup and they needed to talk things over to calm things down. Her mother, pregnant with a sibling, and her father had also been present. A fire broke out and the burnt bodies of her father, her mother and her aunt were found in the ruins. It turned out that all three of them had been poisoned before they were consumed by the fire, leading to the conclusion the jilted boyfriend killed everyone after their chat went wrong. The case was never solved, but Hiiro seems quite interested in the account of the now-adult photographer about her childhood. As said, this story is relatively short and features few characters, making it a bit easy to guess how everything falls into place eventually, but it is a neatly constructed mystery, with a lot of subtle clewing. This is the second time I read the story, but it only made me realize how well the story is written, as so many little passages and comments take on a completely different meaning once you know the truth.

Shi ni Itaru Toi ("A Question Unto Death") has a great premise: the Red Museum is asked to release the files and evidence on the death of a man found near the Tamagawa River twenty-six years ago to the homicide division of the MPD, as the exact same murder has occured: from the location of the body to the location of the wound, down to the fact a blood sample of an unknown person (the culprit?) was left on the clothes of the victim. The police fear the same murderer has striked again and thus need the old files to compare, and Hiiro of course hands over the files, as she too recognizes the eerie similarities between the cases. However, Hiiro is then approached by an old friend in Internal Affairs, who wants Hiiro on the case too: because the new body is too similar to how the body was discovered twenty-six years ago and there's no reason why the original murderer would go such lengths to replicate their own crime, he suspects the new murderer might be just a copycat, and more importantly, a copycat with precise knowledge of the police investigation twenty-six years ago, as the new murder also mirrors the old murder in ways not reported in the media and only known to people involved in the investigation. Hiiro accepts the task and starts investigating both the murders in the past and the present, while the homicide investigation too tries to find a connection between the two cases, focusing on the blood samples found at both crime scenes.

And as I am writing this, I learn there was actually a second adaptation of this series, and that second installment was based on this last story. This story introduces an interesting way to have Hiiro involved in an on-going investigation while also keeping her firmly tied to the work of the Red Museum. The mystery basically revolves around the matter of why the two murders are nearly identical down to every point: if it was the original murderer coming back again after twenty-six years, why would they mirror their own crime down to such detail, even down to something that obviously hadn't been planned originally (the bloodstain left on the victim)? On the other hand, if it's someone copying the murder, how did they get hold of such details and once again, what is the goal in mimicking an old unsolved crime, especially as it wasn't even a high-profile crime (i.e. not the type of murder to attract copycat killers in the first place)? The answer Ooyama has prepared for this question is fantastic: he provides the murderer with an incredibly original motive for this mystery to occur, and while it does require one character to be not quite sane for this story to work, the payoff is great, with a twist that will take the reader by surprise, not only because it's so unexpected, but alo because it's surprisingly well-clewed despite of the out-of-left-field-ness. This is the kind of surprise I'm reading detective stories for!

Akai Hakubutsukan shows once again why Ooyama is so well appreciated as a master of the short mystery story. All the stories except for the pilot/first story are pretty short in page length, but he always manages to pack the plots full with clues and foreshadowing that lead to surprising twists, all the while without telegraphing the solutions too much. I think the series works best when it makes actual use of the fact we're investigating old cases now, with limited options to doing reinvestigations. As I mentioned before, the third volume was released late 2025, but given how much I liked this first volume, I think catching up won't take long.

The House on the Cliff

"Quis custodiet ipsos custodes?"

"Saturae" 

Huh, guess this is the third Monzen review of this year on this blog within just a few months. Pretty rare for me to do reviews of the same author in such a short period of time.

Back in 2024, the bookshops Shosen and Horindou published a facsimile release of Monzen Noriyuki's Shi no Meidai ("A Proposition of Death", which was technically published as his fourth novel, but can also be considered his first novel (see the post for more about that). A "upgraded" version of this  facsimile release was also offered, as it included a booklet with a completely new, original short story by Monzen himself. Tsukiatari no Ie ("The Building in the Cul-de-Sac") isn't long at about fifty pages (which is usually around the lower page range of most Japanese short stories I read), but the set-up is rather memorable, and I think it deserves a brief discussion here.

he book opens with Ninomiya Seiji, a man in his early twenties, arriving at a small building near the sea, built in a clearing in the woods, only reachable by following an overgrown path from the nearest parking spot through the wood for five minutes. The concerete building, slightly bigger than a shed, was used by ama (free-divers, usually women) as a spot to get dressed, rest, and warm up, but has been long abandoned. Inside, Ninomoya finds his employer, Inuzuka. Ninomiya served time after killing a person, and once he was free, it was Inuzuka who was willing to hire him at his construction firm. Ninomiya owes a lot to Inuzuka, as he only still treated him as a decent human being despite his past, and he wasn't a truly bad person either. That said, Inuzuka isn't a truly good person either, and he's been duping people into far-too-costly reconstruction projects. Ninomiya has stood by his friend's side for a long time, but fearing Inuzuka might go too far with his criminal endeavours sooner or later, Ninomiya wants out. Inuzuka agreed, but Ninomiya had to do one last job for him.

And thus Ninomiya arrives at the building, where Inuzuka explains Ninomiya is to keep an eye on a person, who is being held captive. The building consists of two "rooms": entering the building leads to the larger entrance room. In the back of that room, is a smaller room, which has no windows and can only be accessed via the door in the entrance room. The prisoner is being held captive in the smaller room, which is locked with a key and also barricaded with a heavy, sturdy-looking barricade bar, which is held in place with four metal hinges on the wall and the door itself. Ninomiya is to not communicate with the prisoner at all, whether it's him starting a conversarion or the prisoner, but also not treat him badly.  The task will last for seven days. Ninomiya hasn't quite sized up the situation, when Inuzuka also locks the outer door of the building, meaning Ninomoya himself is also locked up. Inuzuka assures Ninomiya he'll come pick him up in seven days, and that someone will bring food for both Ninomiya and the prisoner twice a day (both the outer door and the inner door have a small door near the ground, meant for air intake, through which food can be pushed inside).

At first Ninomiya adheres to his assignment, not talking to the prisoner and keeping to himself. Food is also properly delivered around noon and the evening, so he has not to worry about being hungry. The prisoner however is surprisingly quiet, which makes Ninomiya wonder whether there is a prisoner inside. Fortunately, after some time he does hear a person inside. As the hours and days pass by however, Ninomiya starts to wonder. Who is the prisoner? Perhaps Inuzuka has kidnapped someone, and making Ninomoya a scapegoat, keeping him prisoner too so he can be the fall guy. Ninomiya starts to wonder out loud and even starts to talk to the prisoner, who very occasionally answers with short replies. Ninomiya also keeps a diary, detailing the little that happens during these seven days.

Seven days later, the murdered bodies of Ninomiya and Inuzuka are found: Ninomiya in the entrance room, Inuzuka's body in the locked room, which is still barricaded.

So we have an interesting two-folded mystery here: why is Ninomiya asked to watch a prisoner, while he's being kept imprisoned in the building himself too, and how come both Ninomoya and Inuzuka end up dead in the house (with Inuzuka being inside the room where the prisoner was). It's a very short story, so　I do think some details should have gotten more attention, but on the whole, I did enjoy this story a lot. The first two-thirds of the story read as a thriller, as Ninomiya starts to get more doubts about the task he has been given by Inuzuka, slowly realizing he might be set-up for some huge crime and trying to negotiate with the prisoner in the room to see if they can get out together. But then we shift to a police investigation after the seventh day, in which we not only learn that Ninomiya was mudered, but that also Inuzuka was found dead in the locked room (and Inuzuka died hours before Ninomiya too). While I have only read Monzen's novels, I was both surprised, and not surprised, to see he included diagrams in this story too: he always makes very detailed diagrams and floor plans for his stories, as he studied architecture and it's often an important motif in his mysteries. One could say the same here, though I wasn't that surprised by the "architectural" deception going on in this story: it was in fact the whole deal about why Ninomoya is being kept captive together with the prisoner that presented a fun mystery. Not completely fairly clewed perhaps, but an interesting, and most importantly, suspenseful plot nonetheless.

As this was written exclusively for the Shosen/Horindou facscimile release of Shi no Meidai, I doubt this would be collected in a short story collection if Monzen would decide to write more short stories in the future. I personally would be interested in his short stories though, going by what Tsukiatari no Ie brought! He apparently has at least three other short stories published, so I might try and see if I can obtain them/get copies of them.

Original Japanese title(s):  門前典之「突き当たりの家」

By Dawn's Early Light

"Well, I'll be tougher than the toughies, and sharper than the sharpies -- And I'll make my money square!"

"The Life and Times of Scrooge McDuck" 

Visited Sapporo recently actually. All the dairy products (soft serves!!!) were amazing.

Golden Kamuy is a highly succesful manga series created by Noda Satoru, set in Hokkaido, soon after the 1904-1905 Russo-Japanese War. It follows Sugimoto, a war veteran and the Ainu girl Asirpa on their quest to find a fortune of gold of the Ainu people, with other parties also after the enormous treasure. The manga is well-known for its historical setting, incorporating real historical events into the plot. It also focuses a lot on Hokkaido and the Ainu culture, exploring the Ainu people in that period in time. The manga has been adapted into a succesful anime series, and there's also a live-action film series. 

And of course, there's a mystery spin-off book! Or else I wouldn't be writing about it here.

I have in fact not read the manga nor seen the anime. And I only caught like the only first 15 minutes of the first Golden Kamuy film. So I know next to nothing about the series. But when it was announced last year that not only the very first Golden Kamuy spin-off novel would be a mystery story, but that it was also written by none other than Ibuki Amon, I knew instantly I wanted to read it, even without knowledge of the series. It would not be the first time I have read a mystery book based on a Shonen Jump franchise I'm not super familiar with (which reminds me I also need to read the second Kinnikuman mystery short story collection), and more importantly: Ibuki Amon is basically the person you want to be writing mystery short stories with a historical setting, with plots that utilize the time period to their fullest, ranging from objects and historical events to culture. Golden Kamuy: Tsurumi Tokushirou no Shukugan ("Golden Kamuy: The Aspirations of Tsurumi Tokushirou") is a prequel short story collection set during the Russo-Japanese War and it follows Tsurumi Tokushirou, First Lieutenant of the 7th Division of the Imperial Japanese Army. Tsurumi is in fact the antagonist of the main series, but his popularity have thus earned him the honor of being the protagonist of the book. Tsurumi is a highly strategic, calculating officer who nonetheless cares about the men serving beneath and besides him. The 7th Division is sent deep into Russian grounds as they move from one battlefield to another to support other divisions and Tsurumi, in his position of First Lieutenant, acts as the platoon leader, being the link between command and the men on the ground. In Tsurumi Tokushirou no Shukugan, we see how the 7th Division moves deeper into Russia as the war wages on, but during their deployment, the members of the 7th Division come across several mysterious incidents, including sightings of the ghost of a fallen comrade patrolling at night, the disappearance of a war prisoner from a guarded tent and a series of murders on Japanese soldiers right in the middle of their own camp, without the enemy ever being detected. While these cases baffle his soldiers, it's always Tsurumi who holds the answers to the questions.

I have to admit that while I bought this book without much worries about my non-existing familiarity with the series, I was taken aback by the first few pages of the book, which featured 15(!) named characters of the 7th Division, all with profile pictures and character introduction, and then more pages that explain the military ranks of the people in the 7th Division, and a chart of the battles the 7th Division were involved with during the war. Once you get reading, you'll realize you'll get explained all of this within the stories themselves too, but the front-loaded info-dump pages were a bit intimidating. The book features five stories, which all follow different members of the 7th Division as they encounter weird cases and see how Tsurumi handles all of them. Each of the stories show how these men become devoted followers of Tsurumi, recognizing not only the aspirations of the man, but also the heart he has for the mission and for the men who fight along him, which earns him the respect and loyalty of the men that see his actions in person. While the stories are all completely original creations by Ibuki Amon, the book does feature several original illustrations made for this book by the original series creator Noda Satoru. 

The book opens with Yuurei Hoshou ("The Ghostly Sentry"), which follows Tanigaki Genjirou, Private First Class. The story follows Tanigaki who is put on night guard. He stands on top of a hill, when he hears a bell, and then he briefly spots someone else standing on an opposite hill: for a moment he fears an enemy, but he soon recognizes the face of his fellow soldier Yoshino. He calls out to Yoshino, but the figure disappears, followed by Tsurumi appearing next to Tanigaki. Tanigaki mentions seeing Yoshino suddenly appear, when Tsurumi informs him that Yoshino already died two days ago on the battlefield. So who did Tanigaki see patrolling in the night? This is a story that is less about the how of how the ghost of Yoshino appeared in front of Tanigaki, but more about the why: which is absolutely fantastic. The reason is firmly grounded in the historical and cultural context of the story, being incredibly convincing. It is hard to even hint at the explanation, because I have the feeling a simple nudge in the right direction might give it all away because it's ultimately a surprisingly simple matter, but Ibuki does a great job at not pointing too much at it until the reveal.

Shiroi Nipponhei ("The White Japanese Soldier"), told from the perspective of Warrant Officer Kikuta Mokutarou, starts with Mokutarou on the verge of being shot by a Russian soldier who surprised him, but for some reason the Russian soldier hesitates for a second before he cried out "the White Japanese!" in Russia, giving Mokutarou's comrades the time to save him. Everyone is puzzled by the Russian soldier's cry, because Mokutarou, and all the other Japanese soldiers, were wearing their black uniform. After interrogating the soldier, Mokutarou learns that the soldier had previously had encountered a Japanese soldier in a white uniform, whom he shot at point-blank range, but the soldier was unharmed by his bullet. The Japanese soldiers doubt the accuracy of the story, suggesting the Russian soldier just missed his mark, though they have no idea why the soldier would have mistaken their uniform for black. When later Mokutarou visits a comrade, he's shocked when that comrade asks Mokutarou why he's wearing a white uniform instead of his usual black... This is a mystery story that has a cool idea in regards to the solution, but the way it works as a mystery story is a bit uneven: it's not really structured as a fair clue-to-solution style of story, making the reveal not as satisfying as it could've been. Again, it's less the how that is memorable, but more the why, with this why being a lot more ambitious than the previous one, but at the same time, because of that wider range, a little bit harder to swallow, because it immediately raises questions about the feasibility, something that the first story did much better.

Habutae Tent to Misshitsu ("The Sealed Field Tent") follows Usami Tokishige, Superior Private of the 7th Division. The division has been hastily moving across the battlefield as they are needed to support an important attack. On their way, they manage to capture a group of Russian soldiers and Tsurumi is ordered to interrogate the leading officer, as they need information on the Russian platoons stationed at their destination. While everyone, from Tsurumi's superiors to the men beneath him, suggest beating the information out of the officer, Tsurumi alone suggests treating their prisoner of war with the respect his rank deserves, and the man is kept in a private tent. Usami is one of the two guards placed at the exit of the tent, while Tsurumi goes out for a bit. Tsurumi returns later with some food for the officer, but apparently can't get anything out of the man, so Tsurumi leaves again. Another prisoner however manages to escape and attacks Usami's fellow guard, but eventually Tsurumi and Usami manage to take out the escapee. They suspect the escapee was trying to rescue his commanding officer, but when they look inside the tent, they find the Russian officer is gone! But this is impossible, as there's only one exit out of the tent, and while Usami had been distracted by the attacker for a while, he swears nobody escaped from the tent during his fight in front of the tent. So how did the Russian officer escape? This is the best story of the collection, as it manages to best combine both a good how and why. The way the Russian officer disappeared from the tent is perhaps a bit simple, but it makes great use of the historical/cultural setting and Amon also manages to introduce enough depth to also delve into false solutions a bit. The why is absolutely stunning, and really only works in a war-setting and with certain characters, but it works so insanely well in this story. It is an insane motive and while not as intuitive as what you'd see in the Father Brown stories, there's an essential core to it that does feel like it could've been in a Father Brown story: it hinges on a very instinctivee, emotional concept that doesn't sound logical at all, and yet it is very convincing.

Toki ni wa Yasashiku Minai Furi ("Sometimes Gently Pretending Not to Notice") is told from the perspective of Superior Private Ogata Hyakunosuke. The soldiers in the 7th Division are slowly becoming restless, when they learn there's been a second murder on one of their fellow soldiers. While soldiers dying on the battlefield is not a surprise at all, there's something special about two specific murders: these soldiers were killed in the middle of their own camp. As one would expect, the Japanese camp is set-up far away from the Russian enemy, with night sentries making sure that the camp itself is safe, but twice already an enemy has managed to strike at fellow Japanese soldiers, who assumed they were safe within the confines of their camp. While at first, they assumed some lone Russian soldier might have made his way into their camp and killed one of them before escaping, this theory quickly loses credibility by the second murder, as it's rather unbelievable an enemy could sneak inside the camp twice. Suspicion therefore turns to someone within the camp, so who is this traitor? This story is basicallly all about the why, as the story basically soon points out all the victims were basically just surprised by whom they thought was a comrade. The why is, as is basically the norm for this collection, a memorable matter that only makes any sense in the specific historical/cultural context of the story, being a war-time story of soldiers being gone for months from home, fighting daily deep within enemy grounds. This may even be the shortest story of them all, but the motive definitely ranks among the strongest of the collection in terms of memorability. In practice, you'd think some of the actions of the murderer are a bit contradictionary, but again, this being a story set right in the middle of an on-going war basically makes the motive not only viable, but even believable. 

The final story, Tsurumi Tokushirou wa Madowanai ("Tsurumi Tokushirou Does Not Waver") is about Sergeant Tsukishima Hajime, a very loyal subordinate to Tsurumi, who will follow his orders no matter what. The 7th Division is visited for an inspection by a commander who has been wavering in his leadership of the army as the war continues: while the soldiers fighting the battles on the ground have a feeling they'll get through, the commander is having second thoughts, which might endanger their opportunity at defeating their enemy. Tsukishima is handed a suspicious package by Tsurumi and is ordered to plant alongside the route the commander will be taking during his inspection. The very precise Tsurumi gives about where to place the package make it clear it's not a safe package, and Tsukishima understands Tsurumi is trying to take matters into his own hands to push the Japanese army forward, but Tsukishima apparently mistimed or misplaced the package, as the explosion does result in multiple casualties, but the commander goes unharmed. Will this botched-up attempt at the commander's life mean the end of Tsurumi and his aspirations? Well, now, because otherwise the main series wouldn't have an antagonist.  This one feels more like a thriller than a conventional mystery story, with Tsukishima being ordered to do something that obviously is illegal, and we see him have to deal with the aftermath of his mistakenly planted bomb. Because of this, it's also not a really a well-clewed story, as the emphasis lies more on the emotional turmoil within Tsukishima as he realizes his mistake will have consequences not for him alone, but also for Tsurumi, whom he sees as vital to the division. Of course, as the title says, Tsurumi does not waver and he manages to deal with the matter nonetheless, but the "solution" to what he does is not really set-up with clues or anything. While the solution does recontextualize a few things Tsurumi did or said throughout the story, the twist doesn't feel as strong as some of the surprises we saw in earlier stories in terms of character motivations/actions. It does portray a strong Tsurumi, in a way I suspect that ties deeply to the main series, and in that respect, I can't really fault this story, because I assume most people who read this book are interested in the character of Tsurumi, rather than the mystery set-ups, but I did find it disappointing I found the previous four stories stronger than the finale as mystery stories.

As I haven't read the original series, I can't say whether Golden Kamuy: Tsurumi Tokushirou no Shukugan contains anything that makes this instant recommendation to Golden Kamuy fans: perhaps just knowing it's about Tsurumi's time in the Russo-Japanese War is enough, or knowing which people of the 7th Division are featured in this book. As a fan of mystery fiction however, and as someone who has constantly been admiring Ibuki Amon's historical short story mysteries, I think Golden Kamuy: Tsurumi Tokushirou no Shukugan is overall a very solid book. Ultimately, I don't think my unfamiliarity with the source material really hurt my experience, as Ibuki always manages to write solid mysteries based on well-researched historical and cultural settings and presenting them well to the reader. The stories here are no expection, so it didn't take long for me to be all familiar with the setting, and at the same time, be amazed with the plots Ibuki comes up with based on the setting of the early 1900s setting and the Russo-Japanese War background. So I can safely recommend this book if you're just into cool historical mystery fiction!

While the Clock Ticked

 Are you death or paradise?

 Now you'll never see me cry

There's just no time to die

"No Time to Die" (Billie Eilish) 

Disclosure: I translated Ayatsuji Yukito's The Decagon House Murders, The Mill House Murders, The Labyrinth House Murders and of course, The Clock House Murders.

In 2024, Hulu released a wonderfully produced live-action adaptation of The Decagon House Murders. It just so happened I actually was going to meet author Ayatsuji Yukito the day after it was released, so I binged the series the night before, so I could actually talk about it to him. Like many others, I too was curious how they were going to actually film the book, as it is a very difficult work to adapt for certain media, but the result was honestly really, really good. So when I learnt last year they were going to do an adaptation of The Clock House Murders in 2026, I was thrilled: given how good The Decagon House Murders was, I have only high expectations for this new release, which was released this very week. Obviously, The Clock House Murders is a book dear to me: not only because it's easily one of my favorite books in the series, I also did the English translation of the novel, so I spent a lot of time on, and with the book. 

The live-action series releases today (Friday 27th), so I haven't seen the series yet at the time of writing this post. While they released the complete The Decagon House Murders series on the release day two years ago, this time they are splitting the release across two batches, with the first six episodes presenting the main problem released this week, and the last two episodes, with the solution, releasing next month. So I might binge everything next month in one go. 

To celebrate the release of this adaptation, the literary magazine Shousetsu Gendai (published by Kodansha, the Japanese publisher behind Ayatsuji's House books) featured a The Clock House Murders special in its March 2026 issue, with not only interviews with Ayatsuji, Arisugawa Alice and one of the main actors of the series, the magazine also featured no less than five (!) original "House"-inspired mystery short stories, written by as many authors. 

The first story featured is Aosaki Yuugo's Kubisogiyama no Kaiten Yashiki ("The Revolving Manor on Mt. Kubisogi"). The titular Revolving Manor is one of the six manors built by the legendary architect Kurotsubo Shinku. This particular building stands on Mt Kubisogi in the Hyogo Prefecture, and is best imagined as one of those revolving restaurants that offer a 360-degree panoramic view. The "entrance" of the house is actually just an elevator shaft: the elevator that leads up to the circular house built on top of that shaft tower. The house consist of three "rings". The fixed outer ring is the outer wall of the building, and is made of acrylic: the whole outer wall functions as a window, offering a panoramic view. The middle ring is built right against this outer window/window and holds most of the rooms, liking a sitting room, study and bedroom. This ring slowly revolves clock-wise, meaning each room not only has an amazing view, this view actually changes depending on the time! The inner "ring" is the static center of the house around which the second ring revolves, holding the elevator entrance, bathroom and kitchen.

The house is currently owned by Nishikubo Hiroyuki, who runs a make-up company. He and his wife are visited by a crew from a magazine on architecture for an article on the house. The crew are to stay for the night at this unique creation by the enigmatic architect Kurotsubo. The members all stay in a different room. The following morning however, a gigantic hole is found to have been carved out of the acrylic window. It's clear it wasn't just broken by accident, but someone actually bothered to open a hole in the outer wall. Down on the ground, at the base of the elevator shaft, they find one of the crew members lying dead, seemingly having fallen through the hole down the tower. Everyone is perplexed by the situation: did someone kill him and then cut a hole in the window to dump the body downstairs? But what purpose could that have?

This story is actually a sequel to an earlier Aosaki story, which features another house (The Glass Manor) by the architect Kurotsubo. I have the book, but I haven't read it yet. But it's no problem if you start here. The house in this story is actually pretty "normal" all things considered: I can easily imagine someone wanting a revolving house in the mountains with the complete outer wall acting as a window so you can always enjoy the view! It's not a particularly long story, which is why I was surprised Aosaki manages to pack quite a lot into the story, from a secondary storyline involving the narrator to a few (very short) wrong theories and then we have the actual explanation of what happened and it's... pretty hilarious if you visualize what happened and how the victim found their death. It's not mind-blowing good, but I do like the story for its subdued silliness and I'd love to see a live-action adaptation of this! I think Aosaki could even have gotten away with just that one main idea, so I do appreciate it how he decided to still add some more story details that weren't that necessary.

Ibuki Amon's Tsubaki Fujin no Subarashii Yakata ("Madam Tsubaki's Wonderful Home") is a historical mystery, as we may expect from Ibuki. Set in Manchukuo, we follow private detective Tsukisamu Sanshirou (also appearing in this collection), who is hired to find the brother of a young woman. When their father died, the whole family fortune was stolen by their uncle. The young woman and her mother managed to find some work to earn a humble living, but her brother ran away. He became a robber and eventually made it to the position of captain within his gang of robbers: his robbers already took revenge on their uncle. His sister had not seen her brother in a decade, but recently got a letter saying he had been wounded and was now recovering in a strict medical institution run by a Mrs. Tsubaki: patients aren't allowed to write or receive any letters, but he managed to get one of the suppliers to deliver a letter to his sister for him. He would write again later on, but she never got more news from him and when she asked the deliveryman to go ask at the institution, he was found out by guards and beaten to death. Tsukisamu happens to know Mrs Tsubaki from his time working for the railway ministry. He decides to pay the institution a visit, and is shown a truly wonderful place where wounded Manchurians, from criminals, to simple women and children, are slowly nursed back to health with all the love and care they need... but Tsukisamu knows there's something wrong about the house and the intentions of Mrs. Tsubaki.

I'd be lying if I didn't say I was a bit disappointed when I realized the "house" in this story was not as important as in the other stories in this feature: the focus of the mystery lies more on the intentions of Mrs. Tsubaki and why she is running this hospital. As one can expect from Ibuki, it's a great historical mystery though, set very firmly in the time period and setting of the story, which is of course also fairly original as you don't have many present-day mystery writers anymore who use Manchukuo as a setting. The motive for Mrs. Tsubaki's actions is set-up wonderfully and eventually, Tsukisamu arrives at a heinous plot hiding within Tsubaki's seemingly wonderful hospital. Less of a "add-clue 1-and-clue 2-to-arrive-at-answer 3" mystery, more of a "given-these-remarks, can-you-imagine-why-someone-would-do-this?" type of mystery, but still well-done.

Kesshoukan no Satsujin ("The Crystal House Murders") by Ooyama Seiichirou is set in November of 1990 and first introduces the reader to a group of friends, consisting of Ryouta, Kouji, Shuuichi, Rikka, Maki and Satomi. They are staying at the Crystal House, a small hexagon-shaped hotel in Hokkaido. They have been friends since primary school, and still meet once in a while even now they're all adults. The Crystal House is owned by Ryouta and not in business just yet, but he's giving his friends a sneak peek at his new business adventure. The friends have a pleasant night in the Crystal House, surrounded by nothing but nature and snow, but the following morning, Rikka is found murdered in her room: her head's been bashed in and for some reason, her left hand has been cut off. Rikka has always been the mysterious one of the group, with strange powers of clairvoyance, but is that why she got killed? When they try to call the police, they find the line's dead. Is the murderer someone from outside, or is it one of the friends, and why was the victim's hand cut off? 

This is probably my favorite story in the feature, partially because the story feels the most like a story inspired directly by Ayatsuji's House series, with a few cool nods like the cut-off hand, as well as a great set-up of the narrative: the tale actually starts with a news report detailing how the Crystal House went up in flames and how everyone but one person staying at the hotel had died: one person made it out alive and was saved by the emergency services, but is seemingly suffering from amnesia, with no recollection of the events that led to the deaths of all the people in the hotel. This "book-ending" mystery of who the survivor actually is, and what their role was in the deadly events that occured inside the Crystal House starting with Rikka's death, add a great extra layer to the mystery. The mystery of the cut-off hand, as said, invokes a few moments from Ayatsuji's house series, but the way Ooyama develops this clue feels much more Queenian than Ayatsuji would generally do. So even though the "prop" is the same, Ooyama definitely makes best use of his own expertise, using the cut-off hand for a proper physical-clue-based chain of deduction. I really like what he does with the Crystal House here as a setting too, giving it a unique vibe, and the whole tale feels really complete.

Shasendou Yuuki's Goumonkan no Satsujin ("The Torture House Murders") has the WeTuber Kugi Hikage and her assistant visiting the Torture House, as Kugi is best known for visiting houses with a nasty background stories. Twenty years ago, Horikoshi Toutarou, the original owner of the house kidnapped a few people to torture them to death in his basement with his collection of torture device. One victim managed to escape eventually and notified the police, leading to Horikoshi's arrest. The house, now known as the Torture House, was later bought by Nukube Ikurou and he had an exact copy of the Torture House built next to the original. He has preserved the original Torture House and has a caretaker there keep an eye on things, while he lives in the copy. As this copy houses his collection of antique wares, he has dubbed it the Nostalgia House. He has invited a few people interested in the Torture House and the torture devices kept in the basement to view them, with Kugi as one of his guests. The tour is to be held the next day, but when Nukube doesn't appear in front of the Nostalgia House the next morning as agreed upon, the group crosses a snow-covered field to head for the Torture House themselves. The caretaker there states he did see his master come to the Torture House yesterday. He had assumed Nukube had returned to the Nostalgia House for the night, but the complete absence of footprints in the snow suggest Nukube never left the Torture House. When the group enter the dark basement, they find a dead Nukube, who has been clearly tortured to death, with his joints and bones broken. Unfortunately for the caretaker, it seems that he's the main suspect as he was the only other person in the Torture House last night.

Setting-wise, I really love this story, as the backstory of the Torture House is really cool, as well as the idea of a Nostalgia House full of weird, antique curiosities. It's why I am a bit disappointed that due to the way this story was structured, one person stands out a bit too much as the only viable suspect, which immediately limits the ways the murder could've been committed. The story does make cool use of the torture theme though. I also like the idea of how Kugi manages to trap the murderer in principle, but the way it is written now, the clue depends very much on trivia, while I think it could probably have been written in a way to be a bit fairer towards the reader, if they happen to not have certain knowledge.

The last story, Kokushikan Satsujin Jiken ("The Black Arrow Mansion Murder Case") by Takemoto Kenji, is one I'm not going to discuss in detail. The story is about the detective Norimuzu Rintarou who's asked to look into the disappearance of the owner of the Black Arrow Mansion in Saga Prefecture. Some readers will probably already have realized it by now, but this is a full-on parody of Oguri Mushitarou's Kokushikan Satsujin Jiken, one of the most notorious anti-mystery novels from Japan. Takemoto goes full throttle here, doing not only direct mirrors to scenes from that book, but the story is also absolutely brimming with countless of literary references that may or may not be real and characters who don't speak like humans but like... well, I guess, like AI that tries to sound smart and well-read. The story is basically only fun if you know the original Kokushikan Satsujin Jiken and recognize what this story is mirroring exactly. For Takemoto does that really good, it feels as frustrating to read as the original! (Considering the author's intent, this is praise).

Overall, I think this The Clock House Murders feature in Shousetsu Gendai was pretty fun though, and it's great seeing all these authors doing a take on a house-based mystery. I'm looking forward to watching the live-action adaptation too. If you haven't already though, please consider reading the English translation of The Clock House Murders too, as it's really a great mystery novel!

The Maddest of All

From the lightning in the sky

As it pass’d me flying by— 

From the thunder, and the storm— 

And the cloud that took the form  

"Alone" 

Looking up the etymology of words sometimes points out such obvious connections you never had even considered. After writing the main body of this post, I decided to look up the etymology behind the Dutch word for "lightning", and yes, of course, it does make sense the German "blitzen" is related to the word!

Mephisto is a magazine providing entertainment fiction, with a focus on mystery, but not exclusively so, as it also features stories encompassing sci-fi and other genres. It has gone through a few formats since its inauguration in 1994, and since 2021, it has become one of the perks for subscribers of the Mephisto Readers Club, being published four times a year as its club magazine, featuring serializations of for example the newest House novel by Ayatsuji Yukito, but also original stories written for the magazine. When the contents of Volume 18, 2026 Winter were first announced, my attention was immediately drawn to a new short story by Maya Yutaka: Raimei to Inazuma ("Thunder and Lightning", 2026) is a short story that will be part of an upcoming collection featuring Maya's series detective Mercator Ayu, the brilliant, but self-centred great detective who's always dressed in a neat suit and a top hat and often used as a device by Maya to address meta questions about the literary detective genre. The collection, tentatively titled Mercator Ayu no Gyakushuu ("The Insurrection of Mercator Ayu"), has no scheduled release window yet nor has it been revealed yet what and how many stories there'll be, meaning it might still be years until we see the actual book on the shelves, which is why I decided to discuss this one story early, as I really liked it.

Mercator and his Watson Minagi are staying at the Canaria Lodge, a cosy hotel near a mountain road in Okayama, three hours away from Osaka. Mercator is looking to buy some property, and preferably, haunted or otherwise stigmatized property because that's of course a lot more interesting than a normal home. His search for such a property has brought him near Tsuyama, which is why he and Minagi are taking a rest at the Canaria Lodge, which is run by Ogakie Hajime. Circumstances have left him short-handed, so he has enlisted the help of a handful of members who belong to the same club he used to be in while in university, who just have to help clean a bit, while being offered a free stay at the hotel. Mercator's quest for 'tainted property' leads to Ogakie telling about the legend of a cursed headless Jizo-statue nearby, and how he himself once saw a giant eyeball monster standing at a ridge overlooking the hotel. Mercator of course is interested in the stories, so during the day, he and Minagi go visit these sites. In the evening, they all have dinner at the Canaria Lodge, but rain and lightning cancels any plans for evening strolls. Later that evening, a decorative vase on the ground floor topples over and breaks into pieces. It's clear someone had deliberately push the vase around for it to topple over, but Mercator happened to be nearby as it happened and he didn't see the "culprit" come his way: other people in other places of the ground floor also deny having seen anyone flee the scene towards their location. They then try to ask the people upstairs, until they find one of the students is lying dead in his room, his head bashed in. Who is the killer?

Raimei to Inazuma is a pure puzzle whodunnit by Maya, who is really good constructing these puzzles, but he's also really good at playing with the format by for example taking the format tropes to ridiculous extremes, like the insanely constructed time table puzzle in Mokusei no Ouji, the brilliant set-up of having the reader guess who the victim is before they can proceed with the question of who the killer is and other such playful twists on the Queenian puzzle. Raimei to Inazuma is another fun example of Maya playing around with the format, and while some might be frustrated by the way Maya kinda ridicules the idea of a fair-play whodunnit, it works really well in this story.

In essence, the game presented here is very familiar: we know a crime has been committed, we have a rough idea of when it must have happened, so we need to identify the killer based on the actions we deduce the murderer have taken, and compare that information with the available suspects. Some of these "murderer conditions" are pretty classic ones you'll likely have encountered before in other similar pure guess-the-culprit scenarios, others are quite original: I especially like one major line of deduction of Mercator's solution, which is incredibly cleverly imbedded in the narrative of the story and basically only works because this is a Mercator story, for it would just be too outrageous for any other series detective, but in a Mercator Ayu story? Yeah, that concept goes, and it goes hard! It had me laughing out loud as I finished the story and I definitely think this was one of the best Mercator Ayu stories I've read. I have no idea how the whole collection will look like, but I already want to claim it'll be worth reading for this story alone!

Ultimately, it's just a short story though, so there's not much I can discuss about it here without spoiling anything. I don't really do posts on a single short story often, but I guess I should do them more often. Anyway, Raimei to Inazuma is definitely worth reading for the Maya Yutaka fans, or for those who want to see a mystery author play with the tropes of the genre, exploring the genre to see how ridiculous things can get if one sticks strictly to the conventions. 

Original Japanese stories: 麻耶雄嵩『雷鳴と稲妻』 

The Problem of the Ghost Woman

It is indeed, a fearful place. The torrent, swollen by the melting snow,plunges into a tremendous abyss, from which the spray rolls up like the smoke　from a burning house. The shaft into which the river hurls itself is an immense　chasm, lined by glistening coal-black rock, and narrowing into a creaming,　boiling pit of incalculable depth, which brims over and shoots the stream　onward over its jagged lip.

"The Final Problem" 

Now I think about it, having a waterfall right behind your school is probably not that safe. Sure, high school students aren't stupid, but still, something is bound to happen sooner or later...

Shiotani Ken's Meitantei Futabi (2025) also has the English title The Return of The Great Detective (well, technically it's The Return of Great Detective) and indeed, the book is about the legend of a great detective is given new life again. The Raihen Academy for Girls offers free schooling and accomodations for the family members of those who have contributed to the school's long history, and nobody has contributed more to the safety and reputation of Raihen than the legendary great detective Tokiya Yuu: she was a student at the school in the early 1990s, who solved many incidents that occured at Raihen. While they started out as minor incidents, things soon escalated to even murder. Yuu eventually figured out there was a mastermind behind all these crimes: Yuu confronted the mastermind at the waterfall behind the school and in the subsequent struggle, both fell down, with Yuu's remains never recovered. Tokiya Shou had never heard specific stories about her great-aunt, which is why she's surprised to learn she gets to study at the prestigious Raihen Academy for free. When she arrives at the school, she's welcomed as if she were a princess, as for Raihen, Yuu was indeed a queen. In fact, the dorm director was a student at Raihen herself in the early 1990s and assisted Yuu. Shou becomes classmates with Mima Shizuka, president of the newspaper club with a knack for making up stories. Shou is first shown around the school, which has memorial plates for Yuu all over the place, commemorating the various incidents she solved, like the mystery of the unconcious student in the communal bathroom or the murder of a student in the art room. 

The rumors of Shou, a relative of Yuu, soon spreads across the school, and it doesn't take long for a student to ask Shou for help. She recently got a polaroid camera, and while playing around with it, she and her friends took risqué pictures of each other in the bathroom while getting undressed. However, after they had their bath, they found the pictures missing, and now she got a blackmail letter with one of the stolen pictures, demanding for money. The victim rather not have the police involved, which is why she wants Shou to help. The problem: Shou isn't any good as a detective. Of course, just because your great-aunt happens to be a great detective, doesn't you are, but Shou can't say no, and ends up accepting the request. Out of her wits, Shou strolls to the waterfall where her great-aunt met her end and to her great surprise.... a ghost appears! The ghost agrees to help Shou and act as an armchair detective for her, if Shou helps gather her remains and properly bury her, so her spirit can finally pass on to the life beyond. The case is soon solved, earning Shou a reputation as a great detective herself, but then more incidents start to happen at Raihen, and another figure who saw Yuu's ghost, starts plotting against Shou...

It's of course no coincidence the school's called Raihen (Reichenbach) and that the great detective and her nemesis both died falling down a waterfall. The book's not designed as a Sherlock Holmes pastische though, nor are there really meaningful references to Holmes canon beyond these ones, so you don't need any knowledge of Holmes to enjoy this book. The book is structured as a connected short story collection, where Shou is confronted with ever-escalating cases during her time studying at Raihen, culminating in a grand finale involving both her great-aunt and her nemesis. One thing I have to mention first is how different this book is than Hakushaku to Mittsu no Hitsugi ("The Count and the Three Coffins"), the only other book by Shiotani Ken I have read at this point. That book was a historical epic with drama and tragedy like a Dumas novel, while this is a fairly light-hearted, comedic short story collection set at a girls' high school. Shiotani Ken does like using unusual settings/ideas though, and that's what we do have here too: Shou being helped by an armchair detective ghost each time, all just to maintain her reputation as a great detective herself (or as her excuse goes to keep the family name high). This device has some parallels to how Conan feeds Mouri his answers to maintain the Sleeping Kogorou's reputation high, only in this case, Shou herself wants to be fed all the answers, as she genuinely isn't smart enough to solve the crimes herself (though she does get "educated" as a great detective herself slowly but surely over the course of the book).

While I do describe this book as a short story collection, the individual mysteries are not titled as "stories", but as "chapters" in a novel, so I guess they do want to present this as a novel rather than a story collection. Anyway, the first story involves the stolen polaroids, with the mystery revolving around who could have stolen the polaroids and how: the only persons to know about the pictures are the group of four who took the pictures in the first place, but the pictures had been put in a locker while they were in the bathroom, and nobody had the pictures on them when they left, so the theft was impossible. This is a fairly short mystery, as it is also used to explain how Shou first went to the waterfall and stumbled upon the ghost, but it is a fairly well-constructed, if simple mystery, doing what you usually expect of an impossible heist story (offering multiple false solutions, offering a true solution that builds cleverly on the discarded false ones). The banter between Shou and all the other school girls is really fun though: not only with her roommate Shizuka (who's a bit insane when it comes to wanting to find a scoop and has no qualms about making things a bit more spicier in her articles), but also with her ghostly mentor, as she too is basically just a high school student who likes to chat about ordinary life (or at least, the ordinary life she saw pass by ever since she became a ghost). The second story is about an assault on an art student that occured in a classroom that could only be accessed via another classroom, that was occupied by the art club at the moment. Again, a seemingly impossible crime, and while I didn't like this mystery on its own that much, I loved how it really built on the previous story, as it showed the previous story had real consequences for the student life at Raihen Academy, making people act and think differently. 

The third story in turn has the first murder: members of the newspaper clubs of several school are invited to the house of an alumnus of one of the clubs. It's supposed to be a kind of training camp to hone the journalistic skills of the members, but Mima Shizuka, who had attended last year too, knows the organizer just uses this occassion to vent his frustrations on the current club members by completely roasting their writings. During the snowy evening, the girls sleep together in the storehouse of the manor, which can only be locked from the outside (as it's not meant to be lived in). During the night however, the organizer is found dead in the courtyard, his head bashed in. The only footprints left in the snow in the courtyard however belong to the victim, with no footprints of the murderer. The victim was furthermore found near the window of a room of the annex, where the guests were sleeping, but the windows on that side can't be opened, so the occupant of that room couldn't have hit the man either. Shou is asked to look into the case, not only because of her roommates involvement, but her uncle, a police inspector, is also on the case and has heard of the exploits of his niece. This is quite an elaborate story, that is great at using the various moving parts of the story (characters) to create a seemingly impossible mystery. The reason why the murderer ended up dead in the courtyard is a bit silly, but well-clewed and the way the culprit created the footprint mystery isn't per se that impressive method-wise, but very convincing motive-wise.

Up until this point, the stories also saw short intermezzos told from the POV of a character, who has also seen Tokiya Yuu's ghost herself, and has deduced that Shou is actually getting assistance from Yuu in solving the mysteries. This person however absolutely hates what Shou's doing, so they set a trap for Shou.

Shou, her uncle, the dorm director and some of Shou's allies have gathered, because they have realized the incidents Shou has been involved with, mirror those Tokiya Yuu solved during her time at Raihen. Yuu at the time deduced a mastermind "M" had been orchestrating all these crimes, and she died during her confrontation with M. It is now suspected a new mastermind has also been behind all the crimes Shou has been involved with. During their meeting however, Shizuka keels over after drinking her tea. A message is then delivered to the room: the tea cups have been poisoned and the door has been locked, with no way to call for help. The only way to open the door and get help for Shizuka, is if Shou drinks one of the cups: only one will not kill her. With no way to go to the waterfall to get help, can Shou manage to solve this mystery herself? The story feels a bit like a Liar Game game, where Shou has to deduce which of the cups is safe to drink (with a lot "if they think I think they think..." type of thoughts). The solution is simple yet elegant, and the story moves right to the finale, where Shou is confronted with the mastermind behind all the crimes and the truth behind the death of her great-aunt. This part of the mystery is elegantly clewed, with great foreshadowing planted throughout the various adventures to build up to this Reichenbach Falls-esque finale. Unfortunately, I already knew a bit how this finale would end up, because I happened to have met the editor of the book who kinda spoiled it to me, but despite my prior knowledge, I did think the mystery was constructed very neatly.

So while Meitantei Futatabi is not at all like the historical epic drama that was Hakushaku to Mittsu no Hitsugi, I did greatly enjoy the book: it's a fun, light-hearted school mystery (the sometimes venomous banter between Shou and her ghostly mentor is especially a highlight) with a clear, overarching story that manages to achieve exactly what it sets out to do. The individual mysteries are often fairly short, but competently constructed and the overall storyline, with Shou slowly growing into a detective herself, is satisfying. This is a great book to read between heavier stuff.

These Names Make Clues

The more that you read, the more things you will know.

"I Can Read With My Eyes Shut!" 

For those interested in the guess-the-culprit games as mentioed below, creative members of the Honkaku Discord  venture each month to present a guess-the-culprit scenario to their fellow members, challenging them to solve their puzzle. Come have a look in the server if you want to try solving such a scenario yourself, or if you want to write one! 

Last year, I reviewed the anthology Suiri no Jiken Desu ("It's Inference Time", 2024) and earlier this year, I discussed Anata mo Meitantei (AKA What A Great Detective You Are, 2022) and Kibun wa Meitantei ("Feeling Like the Great Detective"). The stories in all these anthologies were designed as guess-the-culprit whodunit puzzels, with the stories clearly divided in a "Problem" part and a "Solution" part: all the necessary clues to solve the problem are presented within the first part of the story, so there's often an explicit Challenge to the Reader between these two parts: "this is a fairly written mystery and you have all the clues at this point, so try and solve it!" As someone who loves the puzzle-ness of mystery fiction, I just can't get enough of these stories, so when I heard publisher Tokyo Sogensha was doing an anthology series collecting past guess-the-culprit stories from various writers, I was of course immediately intrigued. I skipped the first volume (released in August of 2025) for the moment, as I already knew a large number of the stories included, but I decided to pull the trigger on the second volume: Yokochou no Meitantei - Hanninate Shousetsu Kessakusen ("The Great Detective of the Backstreets - The Best Whodunits", 2025), which also has the simple English title The Best Whodunits 2, collects seven stories selected by editor Fukui Kenta, who also wrote the foreword in which he looks at the history of such stories and similar anthologies.

The first story in the collection is the title story, Yokochou no Meitantei ("The Great Detective of the Backstreets"), a story by Niki Etsuko and originally released in 1972. The story interestingly consists only out of dialogue between the characters (so no narration) and with the historical setting, it reminds of a rakugo play. The story seems to be set in the Edo period and starts with the discovery of a theft in a small village, so they go to the retired elder to ask him for help. A paper craftsman had finished a scroll for a client and was on his way to deliver the valuable goods when nature called. He placed the package on a rainwater bucket on the corner so he could relieve himself in the bushes, but when he came back, he found the package gone, and no sign of any thief, though there were other peddlers and salesmen walking in the vicinity, who are all called upon to testify who they saw around the time of the theft. The story is fairly amusing to read due to all the merchants chiming in, but the main mystery is simple in design, as you basically only need to identify a certain lie, though to do that, you do need to combine information from various people and the basis for pointing out the lie, is well hidden. There's not really a "trick" here done by the culprit, just the need to find out how the testiminonies of all people fit assuming everyone but the culprit tells the truth. Very decent start.

Alibi Fuseiritsu ("No Alibi", 1973) is a story by Ishizawa Eitarou, a writer I do intend to write more of because his main series is about a police detective in Fukuoka, where I once lived. Alibi Fuseiritsu too is set in that city and starts with police detective Wakumoto receiving a phone call at the police station who says Akama Gouzou is dead, and that's lying in the apartment building next to the police station. Akama Gouzou was the name a real estate swindler had adopted. He had been deceiving people by first befriending people and then offering to sell them land for a cheap price: people handed him all their savings for the dream of purchasing some land to build their own house on it. The police had been investigating Akama already, but someone got to him first, and it's likely the murderer is one of the four people who were deceived by him and had already been trying to track him down after Akama started to lay low. The police had already interviewed them earlier for the swindling case, but the four are visited once again to ask them about their alibis for the murder. However, it turns out none of them have one: each of them claims that they received a call that night by someone purporting to be someone else in the group, with the claim they had found Akama and that they'd all meet at a certain spot to catch Akama and hand him over to the police. However, the calls were fake and they had all been sent to a different lonely spot in Fukuoka, leaving them all without alibis. It seems obvious the murderer orchestrated this so nobody would have a clear alibi for the murder, so how is the reader supposed to find the murderer? Well, based on the clues of course. This is a story that has a great conclusion, but the clues actually pointing to the murderer aren't all as clever as presented. It follows the Queen tradition of having to identify a few characteristics which apply to the murder, but some of those conditions presented in the story are rather questionable, like saying people working in certain professions wouldn't know about something, while that something isn't even something that is exclusive to a profession. Other clues are better and as I said, I do like the idea of what Ishizawa was going for.

Tatsumi Masaaki is a critic of the genre, who has written one serialized novel (which has not seen a collected release) and a handful of short stories. Umoreta Satsui ("Buried Malice") is one of those short stories and deals with an interesting problem. Yajima Tarou is an amateur detective who is asked by Handa Shinzou, a friend of his father, to assist with a problem. Handa and Sone Tamio are both looking for the son of Furuyagi Denjirou: before World War II, the Furuyagi Company was a well-known sales firm and Sone Tamio had joined the firm in his twenties. He became Denjirou's promising disciple, but business didn't go well right after the war, so it was decided to dissolve the firm for now, letting go of all the employees but Sone and Denjirou and his wife retreating to a mountain village. Sone became gravely ill just as Denjirou's wife gave birth to a child. Not wanting to be a burden, Sone gave up his position, allowing himself time to recover at a friend's place while Denjirou and his wife would go back to the city to try and start the business again. Later, Sone learnt Denjirou and his wife had passed away soon afterwards. Sone had been given the business contacts and a full recommendation by Denjirou in case he might not make it, so later on, Sone managed to set-up his own business as a successor to the once well-known Furuyagi Company. But then he later heard Denjirou had actually given up his son before he died, and that the son had been brought up by another family. Handa, the family friend of Yajima Tarou, also heard about this, and now Handa and Sone are looking for the son of Denjirou and they even use a television show to ask anyone with information to contact them. But then it turns out two men called, claiming they are the son of Furuyagi Denjirou. When later the midwife who found the adoption family for the baby is also found, they try to have the midwife identify Denjirou's child, but she's killed before she can make the identification.

I think in some way, it's fairly easy to guess who the fake one is based on the set-up of the story, but I do like some of the clues and the logic behind proving that a lot: some of the clues allow for quite some deep logical reasoning, considering the length of the story, but I think the surprise is a bit weakened because you can instinctively guess the solution to the main problem pretty easily even without those otherwise well-planted clues.

Dial 7 was written in 1979 by Awasaka Tsumao and deals with the underworld: Kitaura Shinya, boss of the Kitaura gang is found murdered in his house. As a gangster boss, he of course has many enemies, ranging from enemy gangs to people in his own gang who may have found themselves treated unfairly. The police have more than enough suspects, but can't seem to find any good clues at the crime scene until they notice the murderer must have used the phone after the murder. While the murderer was smart enough to not touch the phone directly, and used a pencil to turn the dial on the phone, the police was able to find out that the murderer called a number that did not use the numbers 8, 9 or 0. However, this was enough for the police to find the murderer. Though modern-day detectives might have problems with solving this mystery. I like the clues and set-up of this story a lot, but even if you know those old-fashioned phones with a dial, you still probably lack certain "common knowledge" information to solve this mystery, as it really isn't common knowledge now anymore. I do think it's a really clever story with subtle hints, that however is really strongly imbedded in the time/setting it was written for.

Sei Valentine Day no Satsujin ("The Murder on Valentine's Day", 1984) is a very short story by Okajima Futari, set at a baking school, where a group of nine students all made a chocolate-based sweet for Valentine's Day. The idea was to judge each other under the watchful eye of a teacher. They would all bring their creation, cover them up and the chocolates would be assigned a number. They'd then draw lots, and each person had to try out the sweet with the number they got and honestly review the sweet. The second person to try a sweet died however, as it turned out the sweet had been poisoned. But when they match the sweets to the creators, it turns out... the victim ate his own poisoned sweet. What happened here? Very short story, so the solution is also very short and simple. Neat idea, not sure if it's really suitable for this format though.

Hitori ja shinenai ("I Won't Die Alone", 1989) was originally written by Nakanishi Tomoaki as a guess-the-culprit scenario for the Kyoto University Mystery Club, but was also reprinted in a literary magazine in 1990 for a special on the Guess-the-Culprit tradition of the Mystery Club, with Ayatsuji Yukito and Norizuki Rintarou acting as the reader's guide. This is a very complex story and revolves around a group of friends, of whom most are either current or graduated members of a high school cooking club who often hang out with each other. Kouichi, a graduate, recently committed suicide, as his girlfriend Remi (a current member of the club) left him for someone else in the club. They still have gatherings where they cook together, but at the first gathering after the funeral, one of the members falls dead after consuming something: the food was poisoned, but the police thinks it's likely not murder, as no murderer could make sure one specific person would consume that food. They suspect it's suicide, but then the same thing happens again at the after-funeral gathering... If it is murder, how is the murderer making sure their intended victim dies? The answer lies in a series of intermezzos for the reader, where the murderer confesses they are just doing things randomly until their truly intended victim dies, but how is that fair to the reader? Well, it's still incredibly fair, with Nakanishi parading some clues very daringly in front of the reader, and yet, it's likely they will miss it. This is a very good example of a great guess-the-criminal story and certainly among the best in this collection. It's a bit long, but there's so much going on, it never bores and in hindsight, you'll see it's a very tightly writte story due to all the clues.

The final story, Tokeikan no Satsujin ("The Clock House Murder", 1990) by Imamura Aya has a somewhat confusing title. Ayatsuji Yukito has indeed written The Clock House Murders, known as Tokeikan no Satsujin in Japanese (disclosure: I translated the book in English!), but while both stories are pronounced the same in Japanese, they are written differently (different kanji). Both are about houses with clock collections though. In the Tokeikan no Satsujin in this anthology, an elderly man who had been many collecting clocks in his house, but his wife, thinking the house is too big for just the two of them, has them reform part of the house so it can function as a boarding house. Two clocks remain in this boarding house, though these clocks give the wrong time, because the owner likes his clocks to be 'free' and not chained to time. Ookuzu Junya, a writer of mystery stories became their first tenant, and since then, he has introduced more industry-related tenants to his landlord, like an editor and critic. The owner's nephew and niece also stay there, resulting in a rather crowded house. One winter evening, after dinner and Ookuzu has retreated upstairs, an editor arrives at the Clock House to visit Ookuzu to pick up a manuscript. When Mariko, story narrator, niece of the landlord and huge mystery buff, goes up to Ookuzu's room, she finds a letter, where Ookuzu says he's sorry he didn't his manuscript and that he will sneak out of the house and return when he's done. However, Ookuzu couldn't have left the house, as there were people in the sitting room (with a view on the entrance door) that whole evening. Ookuzu however is indeed gone. The following morning Mariko and her brother go out to make a snowman, but they find... a dead Ookuzu outside, covered in snow. How did Ookuzu leave the house, and reappear in the garden as a snowman? This is a delightful story: Mariko is so much fun as the snarky narrator badmouthing people as she sets the scene for the mystery. The mystery of how Ookuzu disappeared from his room is simple in essence, but Imamura builds on that simple concept to turn it into something much more complex, with plenty of clues that allow for some deep reasoning. What is also great is that this story also includes a bookending narrative, that adds another meta-layer to the mystery, making this perhaps my favorite of the collection.

So Yokochou no Meitantei - Hanninate Shousetsu Kessakusen is a very solid collection indeed. It collects stories from the late seventies until 1990, so most of the stories are quite a bit older than the Guess-the-Culprit stories I usually read, but some of these are really good, and I think the collection on the whole is worth a read. I have more of these books already purchased by the way, so expect more reviews about these game-like stories in the future too!
