"The Pale Horse"

Today: a book that is mystery-wise not particularly memorable, but still a book I enjoyed a lot.

The students Mari and Sonoko are driving through a typhoon, on their way to the second house of Minori Kazunori, professor in American literature at their M University. Sonoko has had her eye on the handsome and very rich professor since forever, and the fact he's married, means nothing to her: she plans to have an affair with him, and have him divorce his wife eventually. He's been evading Sonoko's approaches for so long, Mari is rather surprised when this morning, Sonoko calls Mari out of bed with urgent news: apparently, the professor has finally given in to his urges. Professor "Kazu" owns a second house on a mountain on A Plains, near Sonoko's home town, and when she called Kazu this morning, she was told his wife would leave the house for a week later today, and Sonoko could come and stay there. Sonoko has no car of her own, so now she's on the phone to beg for a lift from Mari, who very reluctantly agrees to accompany Sonoko. But not for the reason you'd think: it turns out Mari is having an affair with Kazu for some time now, so why has Kazu now chosen for Sonoko!? Mari agrees to go along with Sonoko (to spring a surprise on Kazu) and together, they hop in Mari's car. When they arrive at the house however, they are surprised by the person answering the door: the young man they don't know seems as surprised as them. He explains he's a student of M University too, and that he was hired to watch the house for a week: he was picked up by the professor's wife earlier today and she drove off again, though she didn't explain where she was going, where the professor was and when she'd be back exactly. Sonoko is baffled, because this wasn't how things were to go: she was going to have her special night with Kazu! But as they are wondering what's going on, more people arrive at the house: first a police detective arrives at the scene, who explains he visited the hotel at the top of the mountain in relation to a case, but on his way back to town, he found the road further down the mountain collapsed due to the typhoon, so now he's stuck. He borrows the phone to call his boss and asks for permission to stay at the hotel back up the mountain, but then a family of three (a couple and the elderly father of the wife) arrive at the house too, who tell them the road further up the mountain, to the hotel has collapsed too. When later the hotel shuttle bus driver arrives at the house too, the party is complete: everyone is stuck in this house until the road's been restored. They divide the rooms among each other (Mari of course sleeps with Sonoko) and after dinner, some of them retreat to their rooms, while others hang out in the living room watching television. However, a very unfortunate chain of incidents leads to.... Mari killing six people one after another in the house. While it was certainly not intended, everyone besides Sonoko ends up killed by Mari (and some in rather gruesome manners). Mari is naturally in complete shock and returns to their room to wake up Sonoko, but it is then Mari discovers... Sonoko has also been murdered! A heavy vase was dropped on her head, and for some reason, her hair had been cut short. While a broken window seems to indicate the murderer came from outside, the fact they're completely shut-off from the outside world, quickly points Mari to one conclusion: one of the six people Mari just killed, must have killed Sonoko earlier! This quickly leads to Mari's one plan for salvation: Mari will make it seem the killer of Sonoko killed Sonoko and the rest, and set things up so it'll appear like then the killer was killed by Mari in self-defence. But in order to do that, Mari must figure out who killed Sonoko in Nishizawa Yasuhiko's Satsui no Tsudou Yoru ("The Night Murderous Intent Gathered", 1996).

I don't always remember where I first learned about a book, but I certainly remember where I first heard about this book: I read this book in August 2024, and a few weeks earlier, the book had been trending on Japanese social media, despite it being a rather old book. The reason is simple: the blurb was just so silly: how does Mari accidentally kill no less than six people!? For that is the honest truth: while Mari in some cases did act in self-defence, most killings were really just... unintended outcomes of sudden movements. The book is actually really funny, even though it is not written in an overt "comedic" manner: the way everything happens is just silly. From Mari "accidentally" doing a multi-kill combo to Sonoko just openly trying to seduce a professor to it turning out that professor is actually having an affair with Mari and Mari constantly bad-mouthing Sonoko both in front of her and behind her back... the characters are over-the-top, and act very comedic, even though the book's tone seems more serious.

The "intention" to be serious can also be seen in a secondary storyline, which follows the police detective Mimoro Katsuya (a co-worker of the police detective who ends up at the house): he's been working on the case of a killer with necrophilic tendencies who's been killing attractive women. During his investigation, he interviewed Kose Tomoe, and the woman has been on his mind since then. After some drinking in the earliest hours of the morning (on the same day as the main plot), he ends up in front of her apartment building and makes his way to her room; an impulse he knows is wrong, but he can't help it. He finds her door not locked and sneaks inside, only to see Kose having sex with a man... but then the man strangles her to death. Mimoro doesn't know what to do: while he wants to help her, he also knows that there's no way he can explain how he came here, sneaking like a stalker into the apartment of a woman he only interviewed once. He flees and several hours later, he's called by his boss who informs him of the murder, but to his great surprise, there's another dead woman lying in the apartment now, and the scene is set to make it appear like that woman killed Tomoe and then committed suicide. Mimoro is the only one who knows that isn't the truth, but can't of course explain he was actually witness to the murder. He tries to find out who the man was who killed Tomoe, which brings him on a curious trail that leads him to a house on the mountains in A Plain....

So the second storyline involves a serial killer of women, and we hear about some other odd cases that have been going on in the region, like a killer of children. In general, these chapters are a bit shorter, and feature a very flawed narrator: Mimoro clearly has stalkery tendencies and is even jealous of the man who killed Tomoe, as he felt somehow disgusted and disillusioned with Tomoe when he saw her having sex with another man. Despite that, he's still trying to do his job and find the killer, and part of the mystery of course revolves around finding out how this plotline relates to the story set at the mountain villa of professor "Kazu".

As you can guess, Satsui no Tsudou Yoru reads more like a thriller than a pure puzzler, though Mari does show off some not particularly memorable, but at the very least, still "logic-based" deductions regarding who could've killed Sonoko (with Mari's own killing spree functioning as an important event to determine where everybody was at a certain time). Ultimately though, this is not a fair-play whodunnit, and a lot of the mystery revolves just around seeing how we learn how several strands of plotlines turn out to be connected by... sheer coincidence. Coincidence is a strange thing in mystery fiction (ha! See this review for example), but as this book is just a thriller, I didn't mind the humongous pile of coincidences at work here: the result is just something so silly, it becomes good. I do like the ultimate manner in which the two plotlines of Mari in the house and the investigation of Mimoro connect, as that was the one thing I really didn't see coming, and there were other interesting hidden parts of the mystery that made an impression on me as they were revealed, and while I doubt many readers would actually have been capable of deducing those parts based on the clues, I can't help but admit Satsui no Tsudou Yoru was just hugely entertaining in its... unreserved manner to present such a ridiculous story, with a straight face.

It's funny though... Nishizawa Yasuhiko is best known for his mysteries with a supernatural setting, from people stuck in timeloops to supernatural abilities to push people to think. This is the first time I read a book by him that does not feature a supernatural/sci-fi element and in a way, it ends up the least realistic one because it's so deliciously silly.

Satsui no Tsudou Yoru is no masterpiece or a must-read by any means, but I did enjoy it immensely because of how ludicrous it could be. The concept of Mari just accidentally doing a multi-combo kill spree is funny on its own, and the thriller Nishizawa writes around that is entertaining enough to keep you hooked for the short, but sweet experience.

Original Japanese title(s): 西澤保彦『殺意が集う夜』

The Sound of Murder

「『ミステリ』では人が死ぬ。人が死なない『ミステリ』もあるが、ほとんどは人が奇妙な死に方をしている。串刺しされたり、バラバラにされたり・・・それは忌むべき物語だ。だがどうして昔の人たちは、『ミステリ』を書き、『ミステリ』を読んだのだろう。どうしてそれを喜んで受け入れたのだろう。人が殺されると嬉しいから『ミステリ』を読むのではないのか？もっとたくさん、人が死ねば、君たちは喜ぶのではないのか？」

 『オルゴーリェンヌ』

 

 "People die in mystery stories. There are mystery stories where nobody dies, but in most of them, people die in curious ways, like being impaled or cut in pieces... these are stories we should abhor. So why did the people of yore write mystery stories and read them? How could they embrace them with such joy? Does it mean they read mysteries, because they become happy when someone is killed? Don't you find it more joyous when even more people are killed?"

"Orgellienne"

I'm never sure what to think of when they change the cover of a book when they release the paperback pocket version, but still keep the same general style/idea of the trade paperback version. Why change it in the first place then...?

A long time has passed since books were banned from the world: books were seen as the source of evil, planting ideas in the minds of people and thus needed to be eradicated from the world. Mystery novels in particular were seen as a shameful past: how could people find pleasure in stories about killing others? However, before all the books were burned, some great mystery fans did everything to make sure future generations could still enjoy mystery fiction: they decided to store all mystery fiction as pure data. These people hid specialized data sets, like a set on "locked room mysteries" with the relevant books and secondary literary in so-called "Gadgets": jewels that hold the data sets and which are imbedded in other items, like a scarf. Chris has inherited such a Gadget, holding the set on The Narrator in mystery fiction, and since then, he has become interested in the forgotten art of mystery fiction, and he hopes to become a mystery writer himself. For that, he needs to find more Gadgets, and that is why he is travelling the world. However, that is a dangerous trip, as Censors are desperately hunting after any remaining books in the world: whenever they locate a book, it's not only the book that gets burned down, but the whole place it was found, just to be sure there are no other books there. The Boy Censors are particularly feared throughout the world: they have been trained since their childhood to look specifically for Gadgets and are relentless in their hunts. However, during a previous adventure, Chris became somewhat friendly with the young censor Eno, who let Chris go despite knowing he was carrying a Gadget.

During his travels, Chris learns an old friend, Kirie, has been looking for him, and he receives a message telling him to go to the place they first met. Chris carefully makes his way towards the harbor town, but on his way there, he runs into the mute girl Yuyu, who is being chased by censors. The two are detected and chased throughout the city, but are surprisingly saved by Eno, who picks the two up in his car. Eno drives to the harbor town, where they find Kirie at a small clinic, as he's very ill and has not long to live anymore. Eno explains Yuyu is being suspected of being in the possession of a Gadget. Yuyu is a housemaid who lives in Carillon House, a house located on one of the "new islands" that have emerged ever since the sea levels have been rising (i.e. it is a part of a city that has become mostly submerged, making it into an island). The censors got anonymous information a Gadget was hidden at the house, and the boy censor Karte and his lieutenant Eve are now at the house looking for it, but last night, Yuyu disappeared, which of course made her the prime suspect of having taken the Gadget away. It turns out that very rarely, once every few months, a cramped path appears between the island and the mainland at low tide, and last night happened to be such a time, which is why Yuyu managed to escape without a boat. Yuyu manages to explain that her master sent her away from the island, but she was not given a Gadget with her. Eno is torn between wanting to let Chris go, and his devotion to his work, and eventually, they decide to go to the island together: they can prove Yuyu's innocence by finding the Gadget in the Carillon House, which should resolve everything. 

The Carillon House is owned by Crowley, a wealthy man who loves music boxes above everything. He has allowed several people to live with him, paying for their food and life expenses, who create music boxes for him and the whole house is full of them. When Chris, Eno and Yuyu arrive at the house, tey find Karte and Eve are rather off-hands with their search for the lost Gadget, claiming it will find their way to them. While Chris and Eno start searching for the Gadget however, they stumble upon a horrible sight: one of the disciples of Crowley is discovered impaled on a steel beam at the light house. But how would one lift an adult body several meters up in the sky and drive their torso through a beam projecting towards the sea? As the search for the Gadget intensifies, more people end up dead, like someone found in the ruins of a toppled building and someone found killed in a tower room which was locked from the inside... Is someone using the knowledge of mystery fiction from the Gadget to commit all these murders in Kitayama Takekuni's Orgellienne (2014), or as the inner work also says: The Girl Who Became a Music Box.

Orgellienne is the second entry in Kitayama's Boy Censor series, and.... no, I haven't read the first one. Yep, I seldom read things in order. I am not sure how much this book spoils about the first, but the book explains the basic premises of the Gadgets and the Censors are the start of the story, and that's the most important thing to know, so it's not difficult to get into this world even if like me, you decide to start with the second book.

Besides Kitayama's Danganronpa Kirigiri series and a few short stories, all the books I have read by Kitayama are either formally, or informally part of his Castle series, which has a distinct, almost fantasy-like atmosphere. While the degree in which differs per book, some of them really don't take place in our world, but a more fantastical world and that's also in Orgellienne: while concepts like book burning and censors isn't fantasy per se, the way people think about books, Gadgets and the way Gadgets work as data sets that can only be activated by special means do make it sound like books are magic in this world. There's also a fairy tale-esque backstory to this book: the prologue tells about a young boy who is taken in by a master music box maker, becoming his youngest disciple and him falling in love with the master's blind daughter, and the ending is tragic, but very fantasy-like.This backstory that of course somehow connects to the current murders at the Carillon House, somehow. Chris' interactions with the mute girl Yuyu also have a dream-like element, as Yuyu shows him the ruins on the island, which is when the post-apocalyptic atmosphere of the series is felt the most, perhaps. The idea of an urban island, a part of a town + forest which has become an island due to the rising water, is pretty cool, as you have complete buildings (that have become ruins) on the otherwise almost empty island. And... for some reason I know had to think of Arkham City from the same-titled Batman game.

As Chris tries to learn more about the house and its inhabitants, he finds them all being rather secretive and before he knows it, people get killed in seemingly impossible manners. Which is of course Kitayama's bread and butter: impossible situations that are quite grand  and almost ridiculous, in this case best exemplified by the stabbed man hanging over a sea cliff, and later someone being murdered in a tower room full of music boxes. To be honest, the actual solutions to these impossible crimes are not the kind of absolute insanity I've come to expect from Kitayama: while they do rely on physical tricks as always, the solutions miss just the right amount of crazy I usually like about Kitayama's work (they are still pretty much of the string & needle variety though) and in that sense, this book was a bit disappointing.I think I liked the impossible death in a building that toppled over the best: the building was lying completely on its side, and the victim seemingly either fell down themselves, or was pushed down through the broken windows of one of the higher floors (which because it was lying on its side, basically became a huge pit). The trick behind the fall is pretty simple, but well hidden with the clues and a good example of Kitayama's focus on physical tricks.

Mystery-wise, I found Orgellienne more interesting in the way it explored multiple/false solutions: Kitayama has the various characters fire various theories and solutions at each other, resulting in a rather exciting story, as everyone has very different reasons for wanting to wrap up the case quickly, but they all come up with reasonably convincing theories and it keeps the reader guessing whether they themselves are on the right track or not. Interestingly, Karte isn't really used as a straight rival detective in this book: while he's younger than Eno, he knows Eno's gone a bit soft as a censor, and Karte definitely works more ruthlessly, but at the same time, he's also content at allowing things to develop on their own and see where it gets him, and he doesn't feel as much as a rival, rather than someone who may have conflicting goals, but can end up on either side depending on his mood and how he wishes to accomplish his goals in the end.

Orgellienne is not exactly the book I'd immediately think of when I think of Kitayama's work: while it does feature Kitayama's trademark locked room murders and physical trickery behind them, the actual tricks themselves are relatively tame, in comparison to his other work. The fantasy-like world he depicts here is perhaps the best I've seen in his work though, with a young boy in look for detective fiction, because it's been banished from this world, and a mysterious house full of music boxes with a romantic, but tragic background story. The series is only two volumes long at the moment, so it's likely I'll read the first one too in the future.

The Man in the Mirror

"Mirror, mirror on the wall..."

"Snow White"

For a change not writing a review of this series months (years) after reading it...

The Mirror House located in the outskirts of Kamakura belongs to Kurozawa Matsutarou, a wealthy man who has many mistresses. The manor was once the home of the twins Kirika and Sumika and their mother, who was Matsutarou's mistress, but after her death, the house was extended with an identical annex, like a mirror and no less than 48 mirrors of varying sizes were installed in both buildings, giving the building its name. When the twins were still young however, Kirika wanted to end her own life and since then, Sumika has learned to live without her sister, especially as Matsutarou kept telling her to forget about Kirika and live her own life. Matsutarou is not a loving father by any means however, and his interest in his daughters is purely political. While he lets his daughters live with their mothers while young, he has them all moved to the Mirror House when they reach a certain age, as he wishes to marry them off in political marriages, and their stay in the Mirror House is merely temporary until Matsutarou has found the perfect partner for them, regardless of their own life wishes. This has already led to tragedy one time, as last year, one of his daughters chose death rather than being forced such a life. At the moment, Sumika is joined by four of her half-sisters: Mahiru, Kurara, Sachiko and Ruri, as well as five servants. One of them is Shizuka, the half-Russian Mary Poppins-esque personal maid to Sumika who occasionally has a foul (Russian) mouth. Matsutarou only visits his daughters once a year to check up on them and to announce their upcoming marriages, but this year, his visit coincides with a heavy storm, which means three of the usual servants are stuck in town, leaving only Matsutarou, his daughters and two servants in the house. At dinner however, lightning strikes, illuminating one of the mirrors he has given to each of his daughters, and invisible lettering written on one of the mirrors is reflected on the wall, saying "Death". This angers Matsutarou and he retreats for the night, but that night, he is found murdered in one of the mirror rooms, being stabbed in the back, but for some reason he was lying on the floor with his feet towards a mirror and his arms thrown in front of him, almost as if he was trying to flee from a murderer inside the mirror.... With no means to notify the police, can the people in the manor be truly certain no more murders will occur in Tsukihara Wataru's Kagamiyakata no Satsujin ("The Murders in the Mirror House" 2020)?

Spoilers: more people die.

Kagamiyakata no Satsujin is the fourth entry in this series starring the pro-active maid Shizuka who each time works at a different place as a personal maid for young girls. The books sometimes namedrop the places/families she worked for earlier, but the books can all be read indepedently and in any order. They are all fairly formulaistic too: each book is set in the Meiji period, and set inside an isolated house with serial murders happening, and Shizuka's always there to eventually solve the case, but what makes this series memorable, despite some hick-ups, is how Shizuka is used: each time she's confronted with a killer, she not only detects, but tries to find ways to proactively stop the killer by interfering with their patterns and that leads to interesting twist on familiar tropes in mystery, for example when in an earlier novel, Shizuka notices the murders are modelled after a set of paintings, so she proposes to just destroy all the paintings to upset the killer's plans. It's these interactions with mystery tropes that make these books fun to read.

In theory, this book has interesting elements: there's a house with two mirrored sections, there are 48 different mirrors spread across the house, the first victim is seemingly killed by his own mirror image in a mirror and threatening messages are written on mirrors to announce the coming deaths. A lot of it is tropey, but that is the whole focus of this series so it never feels too reliant on tropes. However, of the four novels I have read until now, I do think this entry was by far the weakest.

The main trope of this book is the "murder announcement": the killer writes messages alluding to deaths on mirrors before committing the murders and sure, that's a trope, but... Shizuka doesn't really manage to do something really original with this, she doesn't come up with some outrageous plan to turn this "habit" around and have it backfire on the killer, or propose anything unexpected to counter this. Because of this lack of interplay with the trope at hand, Shizuka feels far more passive than in the other books. Because these books tend to be very short and rather light, Shizuka's actions usually felt as one of the major parts of the mystery, and having this aspect of the tale weakened hurts the overall experience a lot. "Announcing a murder" is just less exciting than a murderer who decapitates people, or tropes like locked rooms or mitate... While a large part of the story does ultimately revolve around the question why the murderer would chose to utilize this device of announcing their murders, the answer arrived it isn't that exciting, and gives us a rather mundane explanation you might have seen mentioned in other novels that don't even explicitly try to play with tropes.

This pattern also carries over to the whole theme of mirrors in this book. Like, cool, we have a building that is mirrored with an annex, and they feature over 40 mirrors installed here and there... but we never get a floorplan of the building, so the whole concept feels criminally underdeveloped! I wanted to see cool clever things with mirrors which become clear once you start drawing lines in the floorplans, not just vague descriptions of where mirrors are placed! The way the mirrors are used for the murders in this book is far from surprising, and also not really well-hinted, so it feels underwhelming. There is a neat twist regarding the theme of mirrors halfway through the book, but the implications it has for the murders feel a bit forced, and ultimately, I feel this is the book in this series that would've benefitted of more page real estate: the book has many ideas that could've been worked out in more detail, but this particular label releases light novels of a certain length (relatively short) and thus the reveal feels not as satisfying as it could've been, as I think more pages to set-up the twist more with more foreshadowing would have made it a bit more impressive.

Kagamiyakata no Satsujin is thus my least favorite of the Shizuka novels until now. It doesn't help the major trope it focuses on doesn't allow for that much original plays, but the murders themselves are also a bit disappointing, with some underdeveloped tricks and while there's one big twist halfway I do like as a concept, that too should have been given more build-up space for maximum effect. At the moment, there's one more volume, so I'll probably read that one too, but I might wait a bit, because this one was quite disappointing.

Original Japanese title(s): 月原渉『鏡館の殺人』

The World's End

"We cannot conceive of a life other than this one - of a life after death. We can visualize only a continuation of what we know. We have no real belief in a God."
"Death Comes as the End"

It's just a feeling, but I have a suspicion a majority of posts on snow-themed mystery stories on this blog are actually published in the warmer half of the year...

As I announced in my review of The Werewolf Murder Case in volumes 14~16 of Kindaichi 37-sai no Jikenbo ("The Case Files of Kindaichi, Age 37"), the plan was to wait until a full story was released before I'd do another review of this series within the Kindaichi Shounen no Jikenbo franchise, where we follow a now middle-aged Kindaichi Hajime as he gets involved in murder cases despite not wanting to solve mysteries anymore. But then it was announced this series would wrap up last year. So I figured, as stories in this series usually carrying over across multiple volumes, I might as well just wait until the last volume is released to do a review of the remaining volumes. So volume 18 of Kindaichi 37-sai no Jikenbo was released earlier this year... and I completely forgot to get the volume. So that explains why this review is coming now so late after its release. Anyway, volume 16 first starts with the very last chapter of The Werewolf Murder Case, where we learn about the motive for the murders in that case (yes, it's revenge, it's always revenge), but then it's back to business as Hajime's assigned to a new project for his event-organizing company: Hijiri Island, a mountainous island in Hokkaido wants to drive its economic activity by profiling itself as the perfect resort for backcountry/off-piste skiing. Hajime and his subordinate Marin are to check out the place and will be staying in a lodge high up in the mountains, a place only reachable via helicopter. They will be joined not only by someone from the municipality, but also by the backcountry ski team of the skiing club of the Imperial Women's University, a prestigious club whose members often appear in the World Cups. The team always trains here, so they know the grounds well, so Hajime and Marin will be questioning the young women about the mountains in order to develop the place as a resort. Everyone is to stay in a newly built lodge, but the evening they arrive, they find someone has tampered with the heating, and it's slowly starting to become freezing cold inside. 

Fortunately, the old lodge is 500 meters away from the new lodge, and everything should still work there, so they decide to move to the old lodge: the men go first to make sure heating there does work and to carry the kerosene, while the women will follow later with the food supplies. The men have just arrived at the old lodge and starting to prepare for their stay here, when the women in the new lodge use a walkie talkie to contact the men: one of the skiers has gone missing, and there's blood in the hallway. Two of them return to the new lodge, while Hajime and the municipal official stay in the new lodge, but then they discover the body of the missing skier: her head has been cut off, and placed on her lap! When everyone has moved to the new lodge, they learn that their radio is not working and the skis have gone missing, making it impossible to contact with the outside world nor to go down the mountains themselves. By discussing the case, they discover that while nobody has an actual alibi for the murder, as they don't know what time exactly the victim was killed, everyone does have a soft alibi: nobody could've carried the body from the new lodge to the old lodge unseen: the round-trip would've taken quite some time, but nobody was gone for long times/went unseen between the time the victim was last seen alive and the time the body was found. Soon one of the women suggests it's the headless skier: two years ago, a team of skiers got stuck on the mountains when the weather suddenly changed for the worse. Stuck in the cold and with no way to call for help, the team's leader volunteered to ski down the mountain alone to get help. However, after she left, a rescue helicopter found the remaining team members, but the leader never made it off the mountain alive. Only her cut-off head was later discovered: someone had strung piano wire between trees, so when the leader was hurrying down the mountain to get help...  Some say a headless skier is now haunting the mountains, but is this ghost also responsible for the murder, or is this the work of a living and breathing human?

You know, The Headless Skier Murder Case, which spans volumes 16 and 17, has a funny setting. Closed circle settings in this series are often either on an island or somewhere in the mountains... so why not set the story on a mountain, on an island, writer Amagi must've thought. But if this fusion of ideas sounds like he was trying to cook something grand, I'll have to disappoint you, as The Headless Skier Murder Case is a surprisingly simple case, basically revolving around one single trick. The mystery revolves around the fact nobody is ever gone long enough to allow them to carry a dead body and their head to the other lodge and return, which thus gives them all an alibi. This mystery is repeated later, as another dead body is found, this time at the new lodge while everyone was staying in the old lodge. The problem is that it is really just this mystery that drives this story, and the solution is not only a concept we have definitely seen previously in this series, in those stories we ususally get more than just this one idea, so there they can at least benefit from being presented as more difficult puzzles as they are interwoven with other ideas. Here, the problem is presented so bluntly it's nearly impossible to not guess what's going on. The big surprise is actually when the murderer is revealed and they start explaining their motive (yes, it's revenge, it's always revenge), as we learn how this person had been directed by a certain character to commit these murders: while the identity of this person won't be revealed until the next story, I *kinda* suspected who it was, though I thought it would be cheap, and then it turned out it was really that person and now I have no idea how this is going to develop in future series. 

The final volume of this series, The Sealed Space in the Sky Murder Case, starts with Hajime confronting his old nemesis The Puppeteer from Hell, a "crime consultant"-esque character who helps people bent on revenge by supplying them with perfect crime plans. While the Puppeteer has been in prison all this while, Hajime knows the Puppeteer has disciples: they call themselves the Olympian Gods, with the Puppeteer as Zeus the omni-god and Hajime has already encountered and captured a few of them. But after a conversation with the Puppeteer and a hint from his cousin Fumi, Hajime realizes one of the Olympian Gods, Hephaestus, is actually a person near him: he deduces Hephaestus is someone at his work, and that Hephaestus, with the help of another inside person at the company, has been keeping tabs on Hajime, which is why all these murder cases have been happening to Hajime each time he's gone on a business trip. Hajime has a pretty good idea of who Hephaestus's accomplice in the company must be, but the moment he decided to keep tabs on her, she ends up dead: ostensibly via suicide by throwing herself off the rooftop of the company building. She had borrowed the key to the rooftop to water the plants there, and as the key was found in her pocket, the rooftop door was indeed closed/locked and the guard kept the spare key safe, it looks like a genuine suicide, but Hajime knows better: Hephaestus must have killed their accomplice to silence her, and used a "sealed space in the sky" murder trick to challenge Hajime himself. But how could Hephaestus left the rooftop after the murder, as the door to the rooftop was locked (with the victim down below in possession of the key) and no way to reach the surrounding buildings? Hajime knows this is his chance to nab Hephaestus, and narrows the pool of suspects to a handful, but the list includes not only his direct superior, but even his faithful subordinate Marin...

For a story that is mostly about very quickly wrapping things up and features a very simple trick for its main mystery, I have to admit I liked it better than I had initially expected. A lot of the initial chapters is about trying to bring back the whole story about the Olympians back to the foreground again, as it's not been a priority plot element throughout, usually only being mentioned at the end of a case if the murderer happened to be one of the Gods and forgotten again, but here we get a crash-course on the related previous events and a rather cool deduction by Hajime about who he thinks Hephaestus' accomplice is and why. This is the type of hinting and plotting you very often see in Conan, using its serialized format to plant clues within various stories, across a longer period of time, but Kindaichi basically never uses this, with far more compartmentalized storytelling (and very loosely connected stories), so it's cool to see it utilized here. The 'Sealed Space in the Sky" mystery is relatively simple, with rudimentary visual clues and like the previous story in essence a one-trick-pony, but I do like that the focus in fact does not even lie on the howdunnit, but the whodunnit, as we see Hajime then utilize the howdunnit to cross off the suspects of the list, using Queenian logic to identify Hephaestus. This series more often uses a straightforward way to identify the killer (X making certain utterances/doing certain things/in possession of certain things), so seeing a Queenian chain, even if very short, is pretty cool.  The identity of Hephaestus is perhaps not as interesting as the direct aftermath, as the gameboard is reset to lead into the next series. We do get a brief explanation why Hajime swore off solving mysteries long ago, but we don't get the details, but then it's basically off to the next series. And very literally too, as this volume also included the first chapter of the new series: Kindaichi Papa no Jikenbo ("The Case Files of Dad Kindaichi"), in which Hajime has been a father for a few years while running his own detective agency.  Hajime's new client instructs him to go a certain place on a certain date, and because Hajime is a very responsible father and definitely knows what's going to happen whenever he goes to a remote place, he decides to take his son with him and the two find themselves arriving at an old decrepit hotel that's absolutely safe and where no murders will happen...

Anyway, that wraps up Kindaichi 37-sai no Jikenbo. I have to admit, the initial shock factor of seeing a suddenly aged Hajime quickly waned after the realization that storywise, these cases weren't that different from the usual affairs save for a few rare exceptions like stories with a more urban setting. Some ideas never really come to full fruition I think, but as a limited series, it at least had more direction than the 20th Anniversary series or 30th Anniversary series. The last story at least does a lot to make it feel more like a series on its own, so that helps, though I can't feel super excited about the deal of the Olympian Gods basically halting midway, and I'm still not sure what to think about that one character turning out to be one of the Gods too... I guess I'll have to keep on reading the new series to see if Amagi decides to actually end some of these plotlines anytime soon (I mean, I know Conan is long, but at least it has arcs that actually start and end).

L'Île aux trente cercueils

About midway in the short vista which my dreamy vision took in, one small circular island, profusely verdured, reposed upon the bosom of the stream.

 

 So blended bank and shadow there, 

 that each seemed pendulous in air — 

 

so mirror-like was the glassy water, that it was scarcely possible to say at what point upon the slope of the emerald turf its crystal dominion began. 

 "The Island of the Fay" 

 

You know, that would be an interesting setting for a mystery story, an island where they have these GIGANTIC crosses and some kind of impossible crime happens, like a body appears right on top of the highest cross...

Mephisto is a long-running magazine of publisher Kodansha focusing on mystery and other entertainment genre fiction, featuring columns on literature, but more importantly serializations of for example Ayatsuji Yukito's House novels. While it used to be distributed "normally" as a magazine, its current incarnation is only available if you are a member of the Mephisto Readers Club, with the seasonal release of Mephisto being one of the perks that come with a subscription. Currently the magazine is for example running running the serialization of Ayatsuji Yukito's Futagokan no Satsujin/The Twin House Murders while the last two years, it had Arisugawa Alice's Nihon Ougi no Nazo ("The Japanese Fan Mystery"), which got a book release in 2024. But the subscription also includes other content, including a series of flash fiction by various mystery authors who have to work with the same opening or ending line, and also regularly updated mini-columns on mystery fiction on various topics. Mystery Island was originally a series of short, one-page columns running in the first half of 2024 penned by six critics, who all discussed eleven mystery stories set on... an island. The closed circle setting of an island, where nobody can go to or escape from and you have a limited pool of suspects, is of course a very popular one in mystery fiction ever since And Then There Were None and there are quite a few worth recommending to others, but even I hadn't expected you could discuss 66 different stories. Later the same year, publisher Kodansha published all these columns as one book (with a great cover!), also titled Mystery Island.

The six critics are Aoto Shino, Ooya Hiroko, Katayama Daichi, Sengai Akiyuki, Masamune Q and Miyake Kaho, who each take on eleven mysteries set on an island. They obviously did have some discussion about how to divide the works, as they all will discuss a few of the really famous ones, like And Then There Were None, Jukkakan no Satsujin/The Decagon House Murders, Gokumontou/Gokumon Island and Evil Under Sun, but each of them will also tackle some minor titles you likely had never heard about or wouldn't have expected to be discussed specifically. There is a good selection of both older titles and new ones, with some titles so recent they basically released the same year as when the columns were originally running, like Yuuki Haruo's Jikkai ("The Ten Commandments"). There's also quite some variety in the works discussed, from classic puzzle plot mysteries like the titles mentioned above, but also horror-mysteries like Sawamura Ichi's excellent Yogen no Shima ("The Island of the Prophecy") and weird fantasy-hybrids like Shimada Soji's Alcatraz Gensou ("Alcatraz Fantasy").

The Mystery Island columns however are very short, as they were originally published via LINE (a Japanese social chat platform) and it's best not to look as Mystery Island as a reference book, but rather as a coffee table book, the type of book you just pick up to peruse for a few minutes to read a short column and which you'll lay down and only return to after a while. The tone of each of column is pretty casual, usually containing personal anecdotes of how the critic came into contact with the story in the first place. Each column is basically just a page long, so there isn't much space to discuss any work in detail: they mostly get away with giving a brief outline of the work in place, and add a paragraph on its merits as a mystery story/mystery story set on an island. So for those who want to really know why a specific story is interesting as an island mystery, the columns might feel a bit too short, as they can never really delve deep into the themes and specific characteristics of the work in question, but for those who simply want simple pointers to decide what to read next, Mystery Island is quite effective as they really don't discuss enough to even remotely spoil anything. Because the six authors together do manage to introduce a great number, and a great variety of works, it's likely any reader will find a work they hadn't known about that sounds interesting. At least, I know I have a few new titles on my 'someday, I will read this' list I had not ever considered before. That said, the definition of 'mystery fiction' is quite broad, and seeing a title like Battle Royale here does feel a bit like cheating, but oh well, it's 66 titles, they're allowed to use a (very) broad definition.

Originally, these columns were posted on the subscribers-only Mephisto Reader's Club LINE account, and each column would be followed by a short poll on something kinda connected to the book in question: the one on Gokumontou for example asks if you were the killer, which of the four modern-day actors of Kindaichi Kousuke would you like to have as your opponent. The book release includes the outcome of each of these polls and also contains a write-up of the editors' meeting with the six critics, where they decided how to divide the work, which gives the reader a bit more insight into the selection process.

Oh, and moving away from the contents of this book, and discussing this book as... a book: besides the great cover, it also features some really cool character art by Kikuni Masahiko for all the six critics, in the same style as the silhouette characters of the authors featured in the shin honkaku anniversary anthology 7-nin no Meitantei ("The Seven Great Detectives"). The physical release also has a rather unique slipcase: the slipase is actually open on two sides (instead of one), so normally a book you'd place inside could slip out from the other side... but because this is Japan, the book of course also features an obi (a thin paper wrapper), and it's the obi that keeps the book in place. Really odd design I have never seen before.

 Mystery Island is a rather interesting release now I think about it. It was originally written for subscribers to the Mephisto Readers Club, so in a way, for an audience that is probably more interested and knowledgeable about mystery fiction than the average reader, but as a book, Mystery Island works better as a casual coffee book table than a "reference book for die-hard mystery fans". It's easy to pick up, read a column or two and lay down again, and while none of the columns really go deep enough to really become informative or provide you with some eye-opening revelation, they do a good enough job to point you to the existence of some stories you may not have considered otherwise, or help you decide what famous mystery set on an island you should tackle next, if you hadn't read that one masterpiece before. I wonder if a project like this could be translated/released in English too to casually introduce both the well-known, as well as the lesser known island mysteries from Japan to an English-reading audience, considering its more casual tone.

Prediction: Murder

Six little Soldier Boys playing with a hive

"And Then There Were None"

For some reason, after reading the prologue, I thought this book would be difficult to read in terms of writing style, but I ended up finishing it in about a day...

After continued harrassment by his boss led to a suicide attempt which fortunately was foiled by Sousaku's father, Sousaku returns to his hometown to recover. His childhood friend Jun of course tries to help Sousaku, as does the third friend of the group, Haruo. They decide to go on a trip together, and Haruo suggests going to Mukui Island, a remote island in the Seto Inland Sea. Mukui Island advertises itself as having nothing to offer and it's only inhabitated by elderly people, with all the young people having moved away from the inconveniently located island long ago. The reason they decide to go to Mukui Island is because of the psychic Uzuki Yuuko, who was immensely popular in the late nineties. Jun and the others actually once sent a photograph to Yuuko, asking whether that shadow in the background was a ghost, and they got featured in one of her books. The elderly Yuuko passed away after her visit to Mukui Island during a tour along the islands of the Seto Inland Sea, where she and a television crew would seek out paranormal activity. When she arrived on Mukui Island, she sensed an evil spirit on one of the two mountains of the island, and when she visited that mountain in the night, she suddenly collapsed. She died two years later, but she never quite recovered from whatever got to her on Mukui Island. During her lifetime, Yuuko also left several prophecies, and one of them suggest that twenty years after her death, on August the 15th, six people will die on the island where she too fell. 

Intrigued by this story and because of their own link with Yuuko, they travel to the island, arriving late afternoon on the fourteenth. While Haruo had made arrangements before, he's surprised to learn the inn owner suddenly refuses to offer them lodgings, saying the evil spirit will be coming down the mountain soon. They fortunately find another inn, where a few other outsider guests are, some of them also seemingly lured by the prophecy left by Yuuko. That night, they fall asleep, but when they notice Haruo's gone in the early morning, they go looking for him, and find him floating in the harbor. He's obviously dead and the one policeman on the island determines Haruo must have gone out in the night to buy something to drink and fallen into the water. Mainland police is informed, but due to bad weather it might take a while before they can come. One of the other guests, Kazumi, is a nurse, and she points out that despite what the policeman claims, it's clear Haruo was actually murdered before he was thrown into the sea. But as they deal with Haruo's death, they realize the other villagers on the island are being very succesful at avoiding them. Why? Are they involved in Haruo's death? Or are they afraid of the evil spirit which is said to leave the mountains this day? Or has it to do with Yuuko's prophecy six people will die today? Will the prophecy of the six deaths come true on Mukui Island, and is it the work of a human, or something supernatural? Those are the big questions in Sawamura Ichi's Yogen no Shima ("The Island of the Prophecy", 2019).

In a way, the release of this book on its own is pretty creepy. A book about a group of people visiting an isolated location, of which a prophecy has said that on that specific day, people will die? This book was actually released only a month after Imamura Masahiro's Magan no Hako no Satsujin, released in English as Death Within the Evil Eye (disclosure: I translated the book), so it's basically a complete coincidence two mystery novels about prophecies coming true were released within just a month of each other. The funny thing is Sawamura is mainly a horror writer, though this book is touted as him taking on the challenge of writing a proper (horror) mystery story, so it just so happened that on the rare occassion he decides to do focuson mystery, someone else wrote a story with a similar theme. Fortunately, they both do very different things with the theme.

As Sawamura is mainly a horror writer, I had never read anything by him, but I can say Yogen no Shima is a proper mystery novel that is honestly a lot of fun to read. Of course, a lot of mystery stories do rely on horror tropes (or at least, tropes to stir up some tension/excitement), so in a way, it's no wonder Sawamura does a good job at portraying the creepy island of Mukui, without even showing that much of the island/villagers (as the villagers mostly ignore the visitors from outside). The book does a great job at setting atmosphere, especially as it shows you small fragments of local folklore on Mukui Island that seem connected to the villagers' fear of the evil that roams on the mountain, like creepy black idols being placed around houses, supposedly meant to ward off evil. The story also puts the backstory of Yuuko in the interesting context of the boom in popularity in psychics/spirit mediums in the media in the nineties in Japan. We get references to the works of Yokomizo Seishi (the isolated village with its own customs), but also Mitsuda Shinzou and Kyougoku Natsuhiko (local folklore and rituals, and the origins of said folklore) and I was surprised to see this book addressing issues you wouldn't really see in the works of those authors (also has to do with the time period in which this book is set). I really liked some of the points it made regarding this theme, and it worked all really well in the context of this book, both as clues to the main mystery, as well as just painting a surprising background for the prophesized deaths.

As a detective novel, the focus lies not as much on the individual deaths (yes, of course more people than Haruo die), which are committed relatively straightforward, but more on how these deaths tie to a grander mystery, which connects the whole island and the eerie questions about why the villagers are so genuinely afraid of the evil said to lurk in the mountain and the mystery of whether the prophecy will come true or not. A warning here: don't look in the bibliography of this book, because it might tell you more than you want to know in advance, but I do reallly like how Sawamura wrapped up this mystery. I have seen (well, technically listened to) a mystery with a very similar solution before (and with a similar setting and also with ties to folklore...), but the way Sawamura ties this solution convincingly to the unique setting and folklore of Mukui Island, as well as the backstory of the prophecy, and the execution is a lot better than  I had initially expected it to be.

The book sports a marketing slogan stating that the first time you read this book, it's a mystery novel, and the second time it's a horror novel and that honestly really is a great description. While you can read it safely as a straightforward mystery novel, some of the mysteries that are resolved at the end of the book really invite you to read the book a second time, as knowing a certain facts truly changes a lot of the seemingly innocent scenes in the book into something much creepier. Even knowing what is coming.... nay in fact, knowing what is coming really makes this a scary book. In that sense, Yogen no Shima is written and plotted very impressively, being both rewarding as a mystery novel and a horror novel. 

Yogen no Shima is fairly short and could easily have been just a dime a dozen horror novel, but it's a really effective mystery and horror novel, a good example of a piece of simply well executed entertainment media. I believe Sawamura might have written a few more detective stories, so I'll try to find out what the titles are exactly, for this book certainly made me curious to his other mystery output. I don't think this will end up as one of my favorite reads of the whole year, but certain points of this book I will certainly remember for years to come.

I wonder if at those detective fiction courses at university they actually have locked room murder lectures...

During a holiday, Narumi, the self-proclaimed great detective of the Sealed Door club, invites his fellow member Kakeru (who was recently made his debut as a mystery writer), to go on an adventure together. While Narumi hesitates to tell Kakeru exactly why, they are travelling to a small village deep in the mountains of Gifu called Kagerou Village. When they arrive, they notice a strange church-like building in the middle of the village. They chat a little with the local people there, when they hear a cry coming from the nearby cliff: one of the Jizou statues has toppled on top of her, trapping her legs. Narumi and Kakeru quickly help her, but she then tells them her friend Yasoshima Daisaku fell off the cliff down in the swamp below. There's a dangerous path along the cliff that climbs down to the swamp, so Narumi and Kakeru carefully make their way down to look for Daisaku, who fortunately is safe: he is a firefighter and has experience with this. A tremendous storm starts as they climb up the path however, and it's becoming too dangerous to walk up this way. Daisuku instructs Narumi and Kakeru to find shelter in a cave halfway up the cliff path, while he goes further up to secure a way for them. Narumi and Kakeru are just inside the cave when the ground shakes, causing a cave-in that blocks off the entrance. To their surprise, they find there were more people inside the cave, and as they talk with these people, they learn this cave runs beeneath Kagerou Village and that in recent years, it has actually been converted to a cave hotel: the "church" Narumi and Kakeru had seen above is a wedding venue, and an elevator there goes down to the main part of the cave, which is surrounded by several rooms. The hotel is a somewhat eccentric attempt to attract tourists to the region. They also learn that Daisaku is a local who is to be married soon to Tsugumi, who is one of the people in the cave, as she was being shown around.

The group makes their way back to the main "lobby cave" to take the elevator back up, but when the elevator doors open, they find the nearly deceased Nanako, a local high school student: she's been shot in the cage. When she's asked who did this to her, Nanako points her finger at... Kakeru before she dies. While Narumi can quickly prove it couldn't have been Kakeru who shot her considering they just arrived there, the local people are still a bit suspicious about these two outsiders. They learn the elevator doesn't work anymore and for some reason, there's also no answer when they try the intercom connecting to the wedding venue above, even though there should be people there, and Daisaku should also know they're there. While afraid the murderer might have attacked the people above too, the people below in the cave can only wait, so they stay in the hotel rooms for the night, with Narumi warning everyone to keep their doors locked in case the murderer is still down in the cave, but his warning is not enough to prevent another murder the next morning. When one guest doesn't respond to calls from outside, Narumi and Kakeru try to open the steel door, but are only able to bend it slightly to create a gap, but the gap is enough for them to see the inhabitant is lying dead on the floor. But she has also written something in blood on the floor that seems to point to Kakeru again! Who is the murderer in the cave, and can Kakeru prove this time he really isn't the murderer in Kirisha Takumi's Ragnarok Dou - Akazu no Tobira Kenkyuukai Kagerou Numa he ("The Cave of Ragnarok: The Sealed Door Goes to Kagerou Swamp", 2000)?

Ragnarok Dou is the third entry in Takumi Kirisha's Sealed Door series, about the colorful members of a college club specializing in opening sealed doors. Last year, I read the first book in this series, Doppelgänger-kyuu - Akazu no Tobira Kenkyuukai Ryuuhyoukan he ("The Doppelgänger Palace - The Sealed Door Club Goes to the Ryuuhou House", 1999), which was also Kirisha's debut work. You might wonder why I skipped the second book and went straight for the third book in the series. Well, like with Summer Apocalypse a few weeks ago, I didn't actually choose this book because it was a book in this series. I was looking for books with dying messages as the theme, so when I learned this book had a dying message lecture, it found a place in the to-be-read pile, despite it meaning I would be reading a series out of order. Again. As always.

So yeah, the theme of the book is dying messages and it might be surprising to learn Narumi, the self-proclaimed great detective, comes up with a dying message lecture fairly early on in the book. While he namedrops Doctor Fell, Nikaido Ranko, Mercator Ayu and Sorachi Masaya as eminent predecessors when it comes to presenting a lecture on a specific trope in mystery fiction (locked rooms, no footprints in the snow, motives for creating locked rooms and alibis, respectively), I do have to say I find Narumi's alibi lecture really original. While I have seen dying message lectures before (disclosure: I translated Arisugawa Alice's The Moai Island Puzzle), the one in this book is quite original in that because it is about a message: being there's a sender and receiver, this lecture actually consists of two seperate sections (chapters). In the first Narumi presents a categorization of the type of dying messages a victim may leave behind to denounce the murderer (writing, oral, etc.), so the medium of the message, while in the second part, the lecture goes in detail about why said message might be misinterpreted/not understood (so the signife of the message). But what I liked especially about this lecture, is that it is in fact not just a fourth wall-breaking moment, or just two chapters where Kirisha shows he has done his homework and to provide the reader with context to understand how his twist on the dying message in this book will work. While I can't give details because it spoils one of the cleverest elements of this book, Narumi actually has a fantastic reason to actually be holding a lecture about dying messages, and it's precisely because he does this, they're in the end able to solve the case. Narumi might be a self-proclaimed detective, but.... he's actually truly a very clever detective, who in every other series would have been the protagonist. Narumi's just not lucky here, as the club president Godou is just a little bit smarter than Narumi (though less active). At any rate, I have seldom seen a lecture in a mystery story used in such a clever way in-universe, and that alone makes this worth a read, I think.

As the proper cave entrance is blocked and the elevator broken, the people in the cave hotel find themselves in a closed circle situation, but an odd one, as at first, there's no reason to believe the murderer is still in the cave, and it in fact seems more likely the murderer is on the surface, having shot Nanako and then sending the elevator down. The pistol used to kill Nanako is believed to be the one that should have been enshrined in the shrine in the cave: it used to belong to a World War II pilot who crashed in the swamp. But if the murderer did go up, how come a second murder occured in one of the hotel rooms? The door was locked from the inside, and because it's a steel door with a very sturdy, submarine-esque turn-dial lock, Narumi and Kakeru can't even force the door open with a steel bar, only able to open a minor gap through which they could confirm the victim died. As the story progresses, more people are of course killed in the cave. Meanwhile, everyone is also worried about the people above, for Daisaku and other people should know people are trapped in the cave hotel (especially Daisaku, as his soon-to-be-wife Tsugumi is one of the people there!) and Daisaku's a firefighter who told Narumi and Kakeru he'd inform the rescue unit, but why is nobody coming to their rescue? This leads to a lot of speculation on Narumi's part, and it's here where the book kinda repeats some of the... I wouldn't call them faults per se, but it's definitely something that stood out when I read the first book.

For like the first book, this book does feature a large cast of characters like many closed circle murder mysteries... but the narrative is mainly focused on the recurring characters, in this case Narumi and Kakeru, and later other club members after everyone is rescued and they go over the case again to try and solve it. Most of the book revolves mainly around discussions between just the recurring cast as they go over theories and discuss what they could do next, and the side characters that only appear in this book barely get anything to say before they die. The worst example of this is Nanako, who appears as a dead person right away, and we hear some characters lament her death, but we don't actually hear about how they know Nanako, who she is, and why she was in the elevator or anything. She's just there, dead. Only much later you hear a throwaway line about how one character knew Nanako exactly. This happens with other parts of the story too, where you don't really understand what their role is and how character X knows character Y, because the story is focused on Narumi and Kakeru chatting among themselves, instead of with others. It does allow the story to focus on a lot of the detective plot, as Kakeru and Narumi obviously talk about the ongoing case, but some of the puzzle pieces remain vague because you don't hear the other characters speak up too often. And while I do think the members of the Sealed Door club are fun and their banter does mean we get intelligent, genre-savvy discussions regarding the mystery, like the first book, you do feel some of the other characters should have given more speaking lines to flesh out the mystery more.

As for the mystery itself.... it's really dense! You have multiple dying messages (in the broad sense of the meaning, so writing, gestures, in-actions etc.), a locked room murder, long deduction chains about how the murderer must have been moving both on the surface and in the cave, and while I do think sometimes feel a bit chaotic, ultimately, I think it worked out pretty well. The solution to the locked room isn't that interesting to be honest, and the closed circle situation is resolved in a rather easy manner, but the deductions regarding the dying messages and the reasoning chains that point to the murderer are more memorable, and they work really well in conjuction with the aforementioned dying message lecture. Parts of the backstory of the shrine in the cave, which ties directly to the motive, are interesting ideas, though it's debatable about how "fair" it was presented and at times, this backstory goes pretty weird ways: I wouldn't have found the revelations here in any way weird had this been for example a Nikaidou Reito novel, but this being my second book in the series, I hadn't quite expected Kirisha to tell us this kind of backstory. This is an element I think could have been worked out in more detail to feel both more shocking, but also less... coming out of nowhere. 

The book also provides some more insight into the history of the Sealed Door club and why club president Godou started the club, which likely will tie to the final, fourth book in the series, I assume. These books are easy and fun enough to read, so I will eventually get there, not sure whether I will read the second book first, or the last one though.

Ragnarok Dou - Akazu no Tobira Kenkyuukai Kagerou Numa he is a fun mystery novel that does some original things via its dying message lecture, and for that alone, I think this is worth a read. Like the first book, it's a story that focuses a lot on the recurring characters and often has a comedic tone to it, so like many character-focused mysteries, it's pretty easy to get into, and while because of that focus, I do feel the mystery isn't presented as strongly as it could be, overall, I do always end up enjoying these books. Solid entry, and I'll be sure to read the other two books in the series too.

No, this book is not set in a place where rocks levitate...

It has been three years since the traumatic events at Katsuragi Teruyoshi's family home, and now the great detective and his best friends Tadokoro Shinya and Mitani Rokurou are all studying at different universities, all having an idea of their future. They still see each other often, but they have not travelled together in ages, however, exceptions are made for special occassions: Katsuragi and Tadokoro have received a letter from Asukai Hikaru, the former high school student detective whom Tadokoro looked up to when he was young. A few years ago, Katsuragi and Tadokoro met her, now in her late twenties and working as an insurance agent, at the house of  mystery author Takarada Yuuzan, where they were confronted with a horrible murder. Katsuragi and Hikaru had clashed about their views about what a detective is, so Katsuragi and Tadakoro are surprised to learn she had written them a letter. She informs them she's going to be married to Dotou Kouki, the son of Dotou Raizou, the world famous multi-disciplinary artist, especially known for his paintings, sculptures and architecture. While Kouki is "a normal guy", his sisters have inherited their father's artistic talent, with Yukie being an accomplished illustrator, Tsukiyo a sculpter and Kanon a singer. Because of Kouki and Hikaru's engagement, they're going to have a rare gathering on the last day of the year at Raizou's home the Wasteland Manor: a house with four towers Raizou himself designed, located in what is basically a small, square valley, with the house surrounded completely by four rock walls. 

Raizou turns out to be a friend of Takarada Yuuzan, who has passed away since. It was Raizou who designed the house of Yuuzan, and in exchange, Yuuzan had written a mystery novel set in Raizou's home. It is this unpublished manuscript that worries Hikaru, prompting her to contact Katsuragi and Tadokoro. It appears Hikaru's presence at Yuuzan's manor three years ago had not been a coincidence, but set-up by Yuuzan, and she fears she's being manipulated again by this unpublished manuscript of Yuuzan. She hopes Katsuragi and Tadokoro will come to the house, as her "relatives" and see if they can get their hands on the manuscript and see what is hidden within the pages. Katsuragi has no intention of meeting Asukai again, but he agrees to at least join Tadokoro and Mitani on their way to the house. The three young men meet with Hikaru and Kouki outside the house to discuss what they'll do, but then they are surprised by a heavy earthquake. While they are all unharmed, the road has collapsed and trees have fallen on the road, blocking it completely. Very conveniently, Katsuragi alone finds himself on the outside world side of the road, while the rest are now trapped on the house-side of the road. Katsuragi says he'll go to the nearby town and stay there, while Tadokoro and Mitani will go with Hikaru and Kouki as planned. 

Things soon take a turn for the worse however. Tadokoro and Mitani are introduced to the rest of the family (as well as two other guests), though none of the Dotous seem very interested in them. Everyone is shocked to learn they have been cut off from the outside world, but they have enough supplies to last for about four days. And while there are occasional aftershocks, the house itself is sturdy enough to withstand the violent movements. However, the following day, patriarch Raizou is found dead in the courtyard of the house: the elderly man has been shish-kebab'd on a statue of a knight holding a sword up high and what's more: the murderer has left no footprints in the wet garden. When they go looking for Yuuzan's unpublished manuscript in Raizou's room, they find someone has taken it: is it a coincidence a manuscript about a murder case happening in this house is now missing? Meanwhile, Katsuragi has barely managed to find a room in the only inn in town, which is swarming due to the sudden earthquake and trains not running anymore. His attention is soon drawn to his roommate Ogasawara Tsuneharu, who is acting rather suspicious. Of course, Katsuragi has no way to know that Ogasawara is planning to kill the proprietor of the inn: not because he has a motive to kill her, but some hours ago, Ogasawara had agreed to do a murder exchange: when he was not able to go to Raizou's home due to the road collapse and fallen trees, a woman called out to him from the other side of the blocked road, who offered to kill Raizou for him, if he instead kills the inn proprietor for her. Can Katsuragi and Hikaru solve all the crimes happening in and outside the house in Atsukawa Tatsumi's Koudokan no Satsujin ("The Murder in the Earthy Yellow Manor" 2023)?

This is the third book in the series which now bears the name Manor Quartet, which obviously suggest this series will be four parts in total. The first book had fire and the summer as its theme, the second water and autumn and this third book revolves around earth and winter. So yes, that suggest the final book's theme will be wind (air) in the spring. A murder in a house during a typhoon? Anyway, I enjoyed the previous two books about Katsuragi, the young detective who has the ability to sense people lying to him, and while I had not read the premise of the book before, I was pleasantly surprised to learn that Asukai Hikaru from the first book returned too in a prominent role, so once I got started with this book, I had gone through it really fast.

The book takes on a rather interesting structure: the first third of the book is actually an inverted mystery: we follow Ogasawara Tsuneharu as he makes his way to the Wasteland Manor to kill Raizou, whom he hates for a very personal reason, only to find the road collapsed and blocked by fallen trees. When he grumbles out loud he now can't kill Raizou now, a woman calls out to him from the other side of the road. While they can't see each other, she offers to kill Raizou instead of him, if he then kills the propriator of the local inn. The woman suggest she'll kill Raizou first and use a flare signal so Ogasawara will know she has succeeded in her task, after which he'll kill the proprietor. Ogasawara accepts the offer for a murder exchange, and arrives at the inn, but can only stay he shares a room with Katsuragi. And so Ogasawara slowly starts to plan his murder (luckily, he was already planning to kill Raizou so he has things like poison with him). But as this is an inverted detective, we of course see how Katsuragi slowly starts to suspect his roommate isn't just some innocent guest. But how did he figure it out? This part is fairly short, but I do like the clewing Atsukawa employed to allow Katsuragi to get on the trail of Ogasawara. We know Katsuragi starts to have his suspicions very early on, but the clues that allowed him to zero on his roommate are fairly clever hidden. In the aftermath, Katsuragi learns about the murder exchange, finally realizing his friends Tadokoro and Mitani may be in danger, as there's a murderer in Wasteland House. 

At this point, the book jumps back to the last day of the year, and we now follow Tadokoro, who together with Mitani visit the Wasteland House. Kouki's sisters Yukie, Tsukiyo and Kanon seem not interested in the two men, nor are the two other guests (an art broker and Kanon's manager), but Raizou himself seems interested in Tadokoro, as Raizou is aware Tadokoro and Katsuragi where involved in the incident in the house of his friend Yuuzan, and Raizou also seems more interested in Hikaru's past as a high school student detective, rather than as his future daughter-in-law. The following day however, the man is found dangling from the sword of the knight statue in the courtyard, but how could anyone have lifted the victim and stabbed him on a five-metre high sculpture? As there's no landline phone and for some reasons, their mobiles don't have any reception, all they can do is wait until the road's been restored or outside help comes via some other way, but they don't have much time, as more mysterious happenings occur, from sightings of a masked butler who can escape from a tower room with only entrance even though they were being chased by Tadokoro and someone being shot inside another tower room, even though it was locked from inside and the only window in the room looks out... on a rock wall. With Katsuragi not present, and Asukai Hikaru having sworn off ever playing detective ever again, Watson Tadokoro finds himself forced to be the Holmes himself this time...

In Gurenkan no Satsujin and Aomikan no Satsujin, the respective themes of a mountain fire, and a flooded river added a note of excitement to the mystery: like Ellery in The Siamese Twin Mystery, it wasn't just that Katsuragi and Tadokoro found them having to deal with a musterious murder committed in a house, they also had to deal with an unstoppable force of nature, a force that also had its influence on the murders. In Koudokan no Satsujin, we have one major earthquake at the very start of the book, followed by unpredictable aftershocks, but I have to admit I found the theme not as strong here as in the previous books. The initial earthquake creates the closed circle setting, and also sets up the murder exchange, but from that point on, we just have aftershocks happening now and then. They don't really serve as a constant threat, as they come and go swiftly, and it's not like you can predict them. The earthquakes are not a theme that permeate throughout the novel, only popping up now and then, so that kinda weakens the "earth" theme, even if the couple of themes they do feature in the mysteries, they are integrated cleverly.

 What you can't accuse Atsukawa of, is him skimping on the mysteries though. We have Raizou skewered on a sword in the courtyard, even though there are no footprints left in the courtyard, even though rain had softened the ground last night. We have masked butlers being chased into rooms with only one entrance and disappearing from those rooms. We have a body which appears in a room, even though everyone has an alibi for the time between the discovery of the body, and the last time people visited the room, and many more. What I do like is that a lot of these mysteries do share a common thread, used in a few ways. I have to admit I have read so many of these books by now, I found the big trick a bit easy to guess because I have seen similar ideas quite often, but the execution is well-clewed and because Atsukawa utilized the idea in various ways, it feels fairly substantial, rather than a one-trick pony. The earthquakes in return are featured now and then in the mystery, for example forcing the murderer to do something in a certain manner, or the earthquake creating an unforeseen situation for everyone. As mentioned before, the synergy between this 'force of nature' theme and the mystery isn't as prominent as I had hoped, but when it's done, it definitely presents interesting parts of the mystery.

That said, I do find the whodunnit rather disappointing. The first part is an inverted mystery, so of course who the culprit is, but Ogasawara himself never learns who his partner in crime is, so we don't know who the murderer inside the house is. However, the way Atsukawa planted the clues to point to the murderer are a bit too obvious. While from an in-universe point of view, it makes sense it takes some time for the detectives on both sides to catch up as you need information obtained from both in and outside the house to solve everything, it doesn't mean the reader isn't already in possession of that knowledge, and it makes the attempts to present false solutions feel a bit weak, as you know the big elephant in the room hasn't been addressed yet. 

Overall though, I do like how this book is set three years after the previous books, with a more mature Katsuragi Teruyoshi who has learned to deal with his trauma gained in the previous two books, and we see how that also helps Asukai Hikaru, who has her own trauma. I'm not really that interested in character development, but for those looking for that in a detective character, you can definitely find it in this series, and what I do like is how Katsuragi's character does influence his detecting style a lot: it's his experiences that leads him to act like he does now as a detective, so in that sense, I do like seeing the change in him, as it's directly reflected in the way the mystery is plotted and how Atsukawa decides to have the story solved.

Koudokan no Satsujin is overall a solid third entry. While the earth theme isn't as strongly present here as the force of nature themes in the previous two books and it is overall a bit simpler, I do like the twists Atsukawa presents here, like having an inverted mystery section, and focusing on basically three detective figures in Katsuragi, Hikaru and Tadokoro. Can't wait to see how the last volume will wrap things up!
