A History of Murder

"Step by Step" (Ziggy)

Personally, when it comes to titles of short story collections, I actually prefer those with an original title, rather than being named after a story featured in the collection.

Sashichi is an okappiki, a kind of private detective who is hired by a doushin, the official Edo-period police detective, to serve as the doushin's eyes and ears on the ground in the capital of Edo. The woman-loving Sashichi works in Kanda and is known all around as 'the doll Sashichi', as his handsome face resembles those of Kyoto dolls (kyouningyou). Married to an older woman, with whom he often bickers, Sashichi runs around town, solving mysterious crimes as they happen, usually assisted by his two footmen Tatsugorou and Mameroku. The crimes Sashichi encounters are set in the world of the lowest classes, from merchants, actors to simple restaurant owners, but that doesn't make his mysteries less appealing: from a serial killer who targets women who have lately become models for illustrations hagoita paddles, to a series of murders that appear to mimic a serialized story, there's more than enough to do for Sashichi in Yokomizo Seishi's short story collection Meigetsu Ichiya Kyougen - Ningyou Sashichi Torimono-chou Kessakusen ("Kyougen on A Full Moon's Night - The Doll Sashichi Torimono-chou Masterpiece Selection", 2023). 

While Yokomizo Seishi is now best known for his creation Kindaichi Kousuke, and the books starring him, Yokomizo had other long-running series before he created Kindaichi after World War II: one of them is Yuri Rintarou, but his greatest success, and the series people knew him best for, was the Sashichi series. This is a so-called torimono-chou series, a historical detective series starring a character in a role close to what a modern police detective is. Readers of Japanese fiction in translation might know Okamito Kidou's Hanshichi series, which was the pioneer in that genre. Mind you, when I say historical, I don't mean Yokomizo really minded historical accuracy very much. While the 17(!) stories found here are definitely set in the past, and often do interesting things because they're not taking place in the modern world, the language used is fairly modern, and these stories are really easy to read. 

The Sashichi stories are really short, meaning they were pretty easy to write, and Yokomizo wrote 180 of them between 1938 and 1968! For this volume, editor Suekane Yoshimi selected the 17 stories he deemed as the best ones mystery-wise, and he also penned a very informative afterword, where he goes over every single story and explains precisely why they were chosen for this book and the unique points of each of them. Usually, I discuss all stories in a short story collection in detail, but 17 are just too many, and while the selection itself is varied enough, the stories are usually very simple in set-up and besides a core plot, feature a lot of "series tropes" (Sashichi being a womanizer, him bickering with his wife etc), so it's pretty hard to say something substantial about them without basically telling the whole story.

But I think Suekuni's afterword does a fantastic job at pointing out the more interesting points of these stories. Most importantly, or at least, what I thought the most engaging, is the fact that you can recognize ideas in some of these stories that would later be developed further in some of the more famous Kindaichi Kousuke novels. Some of these tricks in the Sashichi series are a bit simple, and because of the very short length of the stories, often it feels like clues are introduced just moments before the denouement, but at the very least, they are plotted as proper mysteries and often feature just enough of unique historical elements, ranging from popular culture like kabuki to women's sumo wrestling, to keep the reader engaged. But it is really seeing how for example one of these stories utilized a trick that you'd later see developed in much more interesting form in the Kindaichi Kousuke novel Gokumontou. Mind you, I don't really mean you see "proto-versions" of the trick in these stories, like how Agatha Christie's The Second Gong became the longer Dead Man's Mirror, but it's more like you see Yokomizo tackling a trope from mystery fiction here, which you'd also would see in a Kindaichi novel later on in his career. You can thus see him grow as a mystery writer, trying ideas out here and returning to them a decade, or more, later. 

And Yokomizo does also come up with interesting situations with his historical settings. In a few cases for example, there's a killer who removes the arm or hand of a victim, but in a world where you don't have fingerprints or DNA testing, why would a killer remove such part? In a contemporary world murderers might do that to hide the identity of their victim, but why would someone do that in the Edo period? Some of the answers provides are memorable because they are based on historical facts, so that make these stories feel firmly set in this setting, while others feel like they could have been easily rewritten to have taken place in a contemporary setting. Among the 17 stories are for example the first Sashichi story Hakoita Musume ("The Girls on the Hakoita"), where three young women have been featured as models for the art on hakoita paddles die one after another, with their own paddle lying next to thier bodies. In Ikiteiru Jiraiya, a thief thought to have died returns, but this time, the "non-violent thief" has committed murders. Or did he? In the title story Kyougen on A Full Moon's Night, Sashichi visits a party, where he is asked by a mysterious woman to pass on a note to one of the other guests, but later this guest is found dead, and three different clues found on his body, point to three different suspects. Horimonoshi no Musume deals with someone trying to identify his granddaughter, whom he has not met but does know has a certain tattoo on her back, but then two women with that tattoo appear before him. As Suekuni also points however, sometimes the underlying trick/solution does feel familiar to some classical Western mystery fiction, with Yokomizo adapting similar concept to the Edo era.

Personally, I thought having 17 of these stories in one volume was a bit overkill, but overall, Meigetsu Ichiya Kyougen - Ningyou Sashichi Torimono-chou Kessakusen is a fun, and especially very readable short story collection, that gives you a good idea of the torimono-chou subgenre and whereas Okamoto Kidou's Hanshichi series felt rather Holmesian, I would say Yokomizo's plotting in this selection of stories, is definitely closer to the puzzle-type plotting like Christie. Personally I found this book especially interesting having read a lot of Kindaichi novels, because you could really tell how Yokomizo first experimented with some ideas he'd later revisit, but even without that knowledge, the stories here are entertaining, even if quite simple. On the other hand, if these are really the best of the best in terms of mystery plotting of Sashichi, I can't say I am very interested in reading the other 150+ stories.

The Poet and the Lunatics

I like this cute cover!

Publisher Tokyo Sogensha has been offering a fantastic platform for mystery writers who haven't been published yet for decades now with the prestigious Ayukawa Tetsuya Award: the award includes a publishing contract for the winning manuscript, and writers like Ashibe Taku, Asukabe Katsunori, Aizawa Sako, Aosaki Yuugo, Amon Junichi, Ichikawa Tetsuya, Ichikawa Yuuto, Imamura Masahiro, Houjou Kie and many more have all made their professional debuts by winning this award aimed at novel-length works. In the meantime, Tokyo Sogensha has also provided a platform for short stories, which would also be rewarded with publication in their literary magazine. 2022 was the last time this award was called the Mysteries! Newcomer Award, as it is now called the Sogen Mystery Short Story Award. The last winner of the Mysteries! Newcomer Award was Mamon Kouhei, with the short story Lunatic Retriever. This short story is included in Mamon's 2024 short story collection Bokura wa Kaishuu Shinai ("No Pay-Off for Us", 2024), which provides a nice showcase of his mystery plotting skills, as well as his talent for writing characters.

The book opens with Gaitou Interview ("Street Interview"), which offers a seemingly harmless mystery: Kirito is approached by classmate Fujiwara, who needs some help, and Kirito is known for having a very keen eye for details. Fujiwara's sister was recently interviewed on the street about a few topics, like the trend of younger people not reading newspapers anymore. Her sister thought the interview went well, but after it was broadcast, people on the internet started bashing her sister for giving stupid answers, and some even just bad-mouthed her appearance. Fujiwara doesn't know what Kirito can do, but hopes he can somehow make it stop. After a careful examination of the street interview video, Kirito is however indeed able to miraculously stop the bashing. This is a unique kind of mystery, as it doesn't involve any real crime, but it is set-up in a convincing manner, even if some of the clues are introduced too close to Kirito's proposed solution to resolving this matter. It's a mystery you could imagine happen in real-life, and I really like how the story eventually wraps back to Kirito's own backstory of how he became known at school as a kind of detective.

Kaeru-Goroshi ("The Murder of a Frog") is about the comedy duo Frogs in the Well, consisting of Shougo and Mitsunori.  Shougo is introduced to Miki, a great fan of the duo, via a mutual friend, and the two start seeing each other more often, eventually leading to them dating officially. While the two comedians have been working hard on their act, they never had their big break, until they finally manage to win first place in a prestigious comedy contest, which results in them getting more offers for appearances on television. The two are not used to their new succes, getting drained by the constant stream of gigs and to make things worse, Shougo is suddenly rejected by Miki, who, despite still being fond of him, somehow can't stand being with him anymore. It's during this period a comedian from the same agency, who has been in the trade for a very long time without any succes, finally wins his first contest. Masuoka Hideki never had much success, but he was always super nice to his juniors at the agency, so everyone is beyond happy for him, and they all gather at the offices of the agency to celebrate his long-awaited award. They all have something to drink and after a while, people walk in and out the room to make phone calls and smoke, but when Mitsunori goes out on the balcony on the third floor, he spots a dead Masuoka on the street below, and lying next to him, is a squished frog. Considering Masuoka just won an award and had his big break that very night, it doesn't seem likely this is a suicide, and suspicion falls on all who were in the building at the moment, but because it is not clear at first when Masuoka left the room and died, it is difficult to establish who was where when, and therefore who has an alibi or not. After reading the first story, I had mistakenly assumed this book would not feature murders at all, so this was a pleasant (?) surprise. Mamon spins a very Queen-esque whodunnit tale, where you use the various physical clues sprinkled across the tale to cross out suspects off the list, and there are some clever twists hidden in this process too, but what is the most memorable about this story, is definitely the motive for the murder. While a motive is a very subjective thing (one can find a motive satisfying, while someone else not at all), I find Mamon's efforts in presenting this aspect too as a fair-play mystery, and the way he set-up the motive with foreshadowing quite memorable. Considering how the whodunnit-part clewing went and the way the motive was so thoroughly foreshadowed, I can easily imagine this same short (very short!) story be fleshed out into a full novel, and it would've worked as well.

Tsuisou no Ie ("The House of Memories") is a very short story, where a father and his two adult children visit the home of the grandfather, who recently passed away. While going through his stuff, the narrator realizes something odd's going on: he has vivid memories of visiting his grandpa's study, which had bookcases filled completely with books. He hadn't visited his grandfather at home for many years, especially not because they had a fight a few years ago, but he knows his grandfather kept on buying books and that he never ever sold his books... But where have all the books his grandfather had bought after he last visited him, have gone to, as the bookcases in the study were already completely full back then? Cute little mystery that may have a very simple solution, but it just works very well with the theme of childhood memories.

Hayami Shirou wo Oikakete ("Chasing after Hayami Shirou") is a two-party mystery, where the narrator first tells how his classmate Hayami Shirou once saved him from a false accussation at school: trash had been thrown around the pool, and because the narrator had a fight with the teacher of the swimming club at the time, he was accused of the vandal act. Hayami however very ingeniously, and swiftly proves who the real culprit was. The narrator and Hayami now go to the same high school, and Hayami's talents are once again needed, when the football (soccer) club find their storeroom ransacked, with balls and other equipment stolen. The stolen items however are found the following day, having been left somewhere on the school grounds. The way Hayami deduces who the culprit is, and why, is clever and I do like the clues are based on physical senses that usually aren't featured as strongly in written fiction, though at the same time, that is also why the story kinda falls flat for me, as we read a lot about these senses, but while your mileage may vary, I did find it hard to believe how "exactly" for example a character could recognize a lingering smell. I do like the little twist at the end of the deduction process that allowed Hayami to point at the one and only culprit, and the motive works well in this school setting too.

Lunatic Retriever is set at a college mixed dormitory, which has one 'famous' inhabitant: Yoshida Haruka won a literary award at age 20 and has been publishing books these last two years. She's also quite arrogant and doesn't mingle much with the other students living in the dorm. However, that doesn't mean her death isn't a shock. On the day a solar eclipse happens, she is found dead in a storeroom inside the dorm. The storeroom was originally a smoking area inside the common room, with two doors (one opening in, the other door opening out). Before the eclipse, people tried going to the storeroom to get something, but found both doors locked for some reason. After the eclipse, the students find it odd the doors are still closed, so they force the doors open. They not only learn the doors were "locked" because they had been taped tight with duct tape, they also find a dead Haruka lying on the floor, as well as a burning stove. The room being taped shut and the burning stove suggests Haruka committed suicide by carbon monoxide poisoning, but on the other hand, they also are of the opinion Haruka would be the last person to commit suicide. But if it was murder, how did the murderer escape the taped storeroom? This is a very dense story, with a lot to offer: a taped locked room, Ellery Queen style deductions to determine who the murderer is, and we even have a solar eclipse... Because of the clue density, we even have room for multiple people presenting their theories, and interestingly, I think that in terms of the locked room mystery, the final solution isn't even as impressive as the earlier ones. What is really memorable about this story however, is the ending, when we are confronted with what is thematically an absurdly shocking revelation. It is a funny, meta-level observation that in a different work could have catastrophic implications, but it works in this short story setting and gives you some food for thought regarding the mystery genre, while also still functioning as a mystery story itself. The theme, in hindsight, can be found in other stories in the volume too, which wraps things up nicely.

This is the first time I read anything by Mamon Kouhei, and while I am generally more a fan of short stories, and I did enjoy the short stories found here, I have to admit they left me wanting for more, for stories that show the same type of plotting, clewing and ways in identifying whodunnit, but with more room for depth and that is also the case for the motives, there are some really originaly character motivations at display here that result in interesting mystery settings, and I'd love to see Mamon for example trying to do a longer detective novel with such themes. So I'll keep an eye out for Mamon's future output!

"Yellow Yellow Happy" (Pocket Bisquits)

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!

The Bear Detectives

Look for the bare necessities, the simple bare necessities
Forget about your worries and your strife

"The Bare Necessities" (Phil Harris, Bruce Reitherman) 

While I am not in direct contact with current members of the Kyoto University Mystery Club, as a former member I do still follow their social media. Personally speaking, my favorite activity at the club were the sessions with whodunnit/guess-the-culprit scenarios: these were short mystery stories written by club members which were clearly divided in a "problem" and "solution" part. The idea is that everyone is first handed the problem part, which traditionally ends with a Challenge to the Reader. The participants get about 45~60 minutes to read the story and (logically!) figure out who the culprit is of the story. If you think you know whodunnit, you can discuss that with the author and they'll tell you whether you got it right or wrong, and after the initial session is over, the author hands out the solution parts to everyone. In a way, the stories do tend to be a bit formulaistic in form, often following Queen-style deduction methods to prove who the culprit is (the culprit knew fact X. Y is proven to not have known fact X, therefore they can't be the killer), but it's exactly the type of mystery story I love, and it was great seeing different members using this form to tell different tales. And while these stories remain "private" for the club generally, I still liked seeing the KUMC social media account briefly tweeting about once in a while about how they did this or that story this week, and how it was received at the session.

Because of that, I still remember how last year, the KUMC account posted how one of their members had written a Danganronpa fanfic as a whodunnit scenario. As someone who enjoys the quirky mystery game series, I was of course intrigued by this concept, as at least in the year I was at the KUMC, people always opted for "original" settings (i.e. not based on existing IPs). But as with most of these stories, I assumed I'd never get a chance to ever read it as I wasn't an active member anymore, and you generally only get to read the story the time it's read at a club session. However, a few weeks ago, I learned the author, Kunou Junki, had actually self-published their fanfic late 2023, selling it at doujin markets. Which was cool, but again, I wasn't really in the position to visit those doujin fairs to pick the booklet up. It was apparently received pretty well though, and Atsukawa Tatsumi even mentioned the story in his ongoing column on mystery fiction, praising it as a whodunnit scenario and as a Danganronpa fanfic. But then.... a few days ago, Kunou announced they were finally selling the fanfic via Booth. So I finally got to read it.

Danganronpa FF - Ame no Kigou, Soshite Happy Birthday ("Danganronpa FF - Rain Code, and Happy Birthday", 2023) is set at the aptly Doujin Academy, where a group of students, each being extremely skilled in a very specific field, are held captured by Monokuma, a cute-looking, but horrifyingly sadistic robotic bear who has set up a game of death among the students. If a student kills a fellow student, a class trial will be held, in which the participants must decide (vote) on a culprit. If the students manage to identify the real culprit, the latter will receive "punishment" (be executed) and the game will continue (more of these rounds) until there are two survivors left, who are free to go. However, if the real culprit manages to elude suspicion at the trial, they are the one will be released, and all the rest of the students will receive "punishment". Monokuma has been feeding the fears and desires of the captured students, making some of them desperate enough to want to kill their fellow students in an attempt to escape Doujin Academy, but fortunately, up until now, the remaining students have been able to correctly identify the real culprit each time, allowing the rest to survive while the real culprits have been executed. At the start of Danganronpa FF, about half of the initial group of students is already dead, either having become a murder victim, or having been executed as a murderer.

The story is told from the POV of Yomikura Suzu, the Ultimate Narrator, who has been acting as a kind of Watson to Aizawa Seishun, the Ultimate Detective, who has been the MVP in the class trials until now: not only has he been solving most of the murders, he is also trying to figure out a way to escape from Monokuma's prison. After the latest execution, Aizawa hopes to set a plan in motion that will allow them to go against Monokuma, and he decides to rope in Yomikura as his accomplice. While the gymnasium is closed off during the night (22:00 - 08:00), all other rooms in the school are accessible, and Aizawa has found out the dressing rooms in the corner of the lecture hall, in front of the passage to the gymnasium, do have cameras, but no microphones, and are also completely soundproofed, so he spends the whole night discussing his plans with Yomikura there, assured Monokuma can't overhear them. When they leave the dressing room the following morning however, they are shocked to find two murdered bodies lying in the lecture hall and that they have been penetrated with a spear. There's also a bloody trail leading from the gymnasium, through the passage, to the lecture hall. A new game of life and death begins, as the remaining students need to figure out who the killer is, or else they themselves will be executed.

Save for the occasional pastiche, I generally don't read fanfics, so I have no real idea of what the standard is, but I sure found Danganronpa FF to be a very effective one. It starts already with the great cover art and the next page introduces you to the various school rules of Doujin Academy, which will be a familiar sight to those who have played the original Danganronpa games: there are the general rules that explain under what conditions a student can escape the school, but also rules about the night time, about ownership of student notebooks and even about how many people a killer may kill (as in: you can't just kill everyone and win the game in that way.). Most of the rules are exactly the same as the games, so it really feels like this is a story set in that world, even if we're now at Doujin Academy. While the characters are original, the characters have concepts that would seem to fit perfectly in the Danganronpa world, from the Ultimate Narrator, to characters like The Ultimate Twin, the Ultimate Ninja and the Ultimate Mountaineer. This story is set after half of the cast has already been wiped out, so it's a bit of a shame some characters are only mentioned briefly by name only, and I'd love to have seen more of them (I wonder of Kunou is planning more stories/"chapters" set in this world?). However, I do have to say that for the most part, you don't really need much prior knowledge of Danganronpa to enjoy this story as a tale of mystery: the essentials are explained adequately (especially with the rule book at the start of the booklet) and ultimately, the mystery really revolves around these specific murders, committed at this specific point in the ongoing story, so no knowledge is necessary about what happened before, or what happens later or about Danganronpa in a meta way. In Danganronpa terms: this is a specific chapter, with its own case.

As a pure whodunnit mystery, I have to say I was surprised how dense this was. It's been a while since I did a 'real run' of a whodunnit scenario, so I'll be the first to admit my deductive senses aren't what they used to be, but Danganronpa FF seems about a full step more complex than the usual KUMC whodunnit scenario, making it unlikely anyone could have gotten all the points within the usual session time (though perhaps they held a longer session than usual). So yeah, this is a really deep whodunnit story following the Queen format, where you can logically deduce who the killer is by identifying criteria the killer must answer to, and then figuring out who of the suspects answers to all of those criteria. Some of these criteria are relatively easy to notice, allowing you to cross off some names early, but others are really cleverly done, and I am the first to admit that I wasn't even close to the answer model provided by the detective at the end. There are quite a few (very devilish!) twists and turns in the long deduction process (which is why I think it would have been difficult for someone to solve all of the story during a normal club session), but for Ellery Queen logic-lovers, this is really great stuff  and I love a lot of the logical processes shown in this story (the initial step alone of the long elimination process is already really good!). What is even more commendable is how cleverly Kunou makes use of the Danganronpa setting. A lot of the things pulled off here in terms of logic only make sense in a Danganronpa-inspired world, with the school rules and Monokuma antics and stuff like that. So I really agree with Atsukawa here about Danganronpa FF is satisfying as both a mystery story, and a Danganronpa fanfic.

The third act of Danganronpa FF wasn't originally part of the scenario presented at the KUMC, as after the initial murder problem and the subsequent solution part, we are treated to what is basically an in-depth essay on the Danganronpa games as mystery games. If you have played the games (or you don't care for spoilers at all), there are some interesting points made (ha, I hadn't expected Kunou to quote Morooka's academic work on shin honkaku mystery and games!), but it is certainly a part that 'takes you out of the story', so your mileage on this closing part may vary. This part has no direct influence on the logical parts of the mystery, so you could choose to ignore it if you wish to do so.

At any rate, I did really enjoy Danganronpa FF - Ame no Kigou, Soshite Happy Birthday, as both a really well-plotted whodunnit scenario as well as a mystery story written with a lot of love for the Danganronpa franchise. Danganronpa FF was apparently also a reason why Kunou was asked to pen an original whodunnit story for the Mystery Carnival event of publisher Seikaisha held last week. I haven't read that story, but I do hope I get to read more of Kunou in the story, as what I have read here really makes me curious to what more they can come up with. Hopefully, we'll see more of them in the future!

Regarding the English translation of The Labyrinth House Murders

My translation of The Labyrinth House Murders (Yukito AYATSUJI) was released three weeks ago in the UK by Pushkin Press. I hope the people who have read it enjoyed it, and that those who still have to read it, will find it as entertaining as I did when I first read the work. As much as I love the original work however, there was one point in the original work that wasn't likely to work "as is" in an English translation, and after deliberation with the editor and Ayatsuji himself, it was decided I'd change part of the mystery slightly, in order to keep the fair play spirit of the original work intact for the English-language reader. However, I still want people to know what the real idea was Ayatsuji had planted in his book, so I decided to write a piece explaining about what was changed and why, and go over a few other translation-related points while I am at it.

As you probably can guess, I'll be discussing major spoilers for The Labyrinth House Murders in that piece, so you should only read it after reading the book.

You can find the page here, and I will be re-posting this announcement when the US version of the book will be released coming Spring.

"Heroes" (David Bowie)

Gorgeous cover!

Earlier this year, I discussed Yuuki Haruo's Salome no Guillotine, a very memorable mystery set in the Taishou era, revolving around a series of murders among artists. It was only after reading the book I learned it was actually the latest entry in a series. In fact, I only realized that after I first opened the book of today's review, and saw the names of the protagonists of Salome's Guillotine on the first page... Yuuki Haruo's Tokeidorobou to Akunin ("Clock Thieves & Crooks" 2023) is the second book featuring the adventures of painter Iguchi Sakuta and his friend and former burglar Hasuno in the late Taishou era, with the handsome Hasuno with his criminal experience of course being the detective, while Iguchi functions as our Watson. Iguchi and his wife are good friends with the loner Hasuno, who after a short career in relieving people of their possessions has now become mostly an upstanding citizen, though the adventures of the two occasionally force Hasuno to make use of his unique talents again. And yes, this is the second book in the series apparently, so I'm reading these out of order and I have no idea how much about their initial meeting is explained in the first book, but in Tokeidorobou to Akunin, they form a great team. The book is technically a short story collection, but the stories do flow from one into the next, even if there's no tight overarching storyline. 

The book opens with Kaemon-shi no Bijutsukan ("The Art Museum of Mr Kaemon"), where Iguchi has a major problem. Long ago, his father had bought an antique Dutch clock which once belonged to the Dutch royal family. When he purchased the clock, he also received a very well-made imitation of the clock, as the previous owner had been scared of theft. When Iguchi's father sold the clock to the collector Kaemon, he gave the imitation to Kaemon. The latter never noticed it, and Iguchi suspects his late father did it on purpose. The elderly Kaemon has not long to live anymore, and has recently had his country house renovated to include an art museum to display the art collection he gathered throughout the years. This would include the Dutch table clock, and Iguchi is afraid fellow art connoisseurs who will visit the museum will realize it's a fake, and that it will become public his father sold Kaemon imitation art. Iguchi and Hasuno visit Kaemon at his house, to see if they could just apologize and give him the real clock, but the attitude of the grumpy old man makes it clear there is only one solution: Iguchi and Hasuno have to break in the museum and swap the fake clock for the real one themselves. What follows is a fun adventure of Iguchi and Hasuno trying to sneak inside the museum, but while they are there, they notice something is off about the museum, but what? This is one of those mysteries where you don't really know what the mystery is until the conclusion, so I can't say too much about the mystery. But I'd definitely say it's a memorable one! The ingenious twist is definitely set-up very well with both physical and psychological clues, and I love the themes (motive) behind this story. Great opening of the book, especially with the banter between Iguchi and Hasuno.

Akunin Ikka no Misshitsu ("The Locked Room of the Family of Crooks") follows Atsuko, the maid of the Minoda family, who live in a large manor in Yokohama. Patriarch Akiyoshi lives in England with his wife, while his four children live in their parental home in Japan. None of the children, all of different mothers, really like their father, nor each other, but money is a great binding tissue, so they all live together. Oldest son Yukimasa one day receives a letter from his father telling him he is returning from England and he has also sent boxes full of furniture back to Japan. It appears his wife died, and now he's coming back, but his father wants his home in England replicated perfectly in the annex of their Japanese home, hence Akiyoshi not only sending back sofas and chairs, but even the doors. Yukimusa arranges for builders to come and construction starts based on the photographs his father sent him. One night however, as the maid Atsuko returns, she notices a figure floating in the rooms under construction, and when she peeks through the window, she sees Yukimasa's body hanging from a rope, with his legs resting on the bolted door latch (which was also imported from England). She calls the other siblings, but they can only enter the room by breaking the door down: meaning this was a locked room. At first sight, this therefore looks like a suicide, but when Iguchi and Hasuno visit the place (Iguchi's patron had sent Iguchi and Hasuno to sort out something with Yukimasa), they soon uncover not only that all of Yukimasa's siblings had a motive to kill him,, but they also find clues that indicate this was indeed a murder. But how could the murderer have left the locked room? On a purely technical level, the locked room mystery is not very original perhaps, but the way it ties to the motive is really great! It provides a fantastic reason why such a rudimentary trick was used, and the small unique elements of this locked room, like balancing the victim's feet on the latch, do transform it enough to create a good story. But it's definitely the motive, and the final implication regarding the victim, that makes this another good entry.

Yuukai to Ooyuki - Yuukai no Shou ("Abduction and Heavy Snow: Abduction") and Yuukai to Ooyuki - Ooyuki no Shou ("Abduction and Heavy Snow: Heavy Snow") is a two-part story, each focusing on a different mystery. In the first part, Hasuno asked to come disguised as a salesman to Iguchi's sister-in-law's place. When he arrives there, he learns Iguchi's niece Mineko has been abducted and a ransom note has been left in their letter-box. They ask Hasuno for advise, but the latter soon notices several odd points about the ransom note, leading to a surprising conclusion regarding why Mineko was abducted. The story then deals with the drop-off for the ransom, which is done by Iguchi's father-in-law, while Hasuno and Iguchi, in disguise, try to spot the abductors. Again, Hasuno quickly sees through the trickery of the abductors and soon the two are on their way to save Mineko. This chapter is the most adventurous of the whole book, I think, with a good deal of suspense as Hasuno slowly deduces the bigger story behind Mineko's abduction simply based on the instructions in the ransom note. The trick regarding the ransom money drop-off is fairly simple, but it's basically just a set-up to lead into the second part of the story. There we follow the story first from Mineko's point of view, as she finds herself abducted by a group of men. In the night, she's taken by one of the leaders to a hut outside and thrown on a hay bed: Mineko fears the worst and is knocked out by the man. When she wakes up however, she finds that man stabbed to death lying next to her. It is at that time her uncle arrives together with Hasuno, having found out where she was being held, but they have two problems: one is that their car broke down and even if they try to get away on foot now, they'll probably be caught by the rest of the gang in the house next door. The second problem is that the only footprints leading to the hut are those of the dead man, Mineko and Iguchi and Hasuno who arrived just now, meaning the only person who could've killed that man is Mineko. While Mineko has no recollection of killing the man, and Iguchi and Hasuno also don't believe that is the case, who then did kill the man, and how? While it might be hard to guess the details of how this was done, I think the general idea behind the locked room is probably fairly easy to guess, even if it can be a bit tricky figuring out the exact timing. The story then ends in a kind of reverse Home Alone, where Iguchi, Hasuno and Mineko try to round up the whole gang themselves, which results in some funny swashbuckling scenes.

Iguchi, like many of his fellow artists, has found a patron in the art-loving businessman Harumi. In Harumi-shi no Gaikoku Tegami ("Mr Harumi's Letter from Abroad"), Harumi asks Iguchi for some help, or to be exact, he needs the help of Iguchi's friend Hasuno. Not because Hasuno was a burglar, but because Hasuno also knows languages and Harumi needs a translator. His wife passed away some time ago, and he only now got around to sorting out her possessions, but he came across a strange letter from France, even though she did not have any friends there. Hasuno translates the letter, which is sent by the nephew of Marcel Champlain, stating he writes on behalf of his recently deceased uncle, who implored him to write a letter to Japan to express his thanks, and love to Ms Harumi. Harumi has no idea who this Marcel Champlain is, and asks Iguchi and Hasuno to figure out who he is and what his relationship was with his wife. The two dig into the history of Harumi's late wife, which is rather complex: Harumi's recently deceased wife was actually his second, and his first wife was actually her twin sister, who also passed away early, and there was another older sister too. The precise relationship between Harumi and his wife and sister-in-laws is rather complex and can make this story a bit confusing, and again, this is the type of mystery you don't really know was even present until it is explained to you, though I do like the truth Hasuno eventually uncovers, and it gives a very sad, but memorable meaning to the letter sent on Marcel's behalf.

In Mitsukawamaru no Ayashii Bansan ("The Alluring Dinner on the Mitsukawa-Maru"), Iguchi, Hasuno and fellow artist Ootsuki find themselves on the ship Mitsukawa-Maru, as representives of Harumi. The Mitsukawa-Maru recently returned from India, but ran into trouble just off the coast: while the ship itself is in no direct danger of sinking and the crew safely returned to the mainland, it will take a few days before the ship itself can be pulled free. However, the ship was carrying a unique cargo: two tigers.... which are going to be served at dinner. Hirokawa Koutarou, the owner of the ship, also runs a shady secret club where the members can enjoy strange things, which is why he had planned a dinner party with tiger meat. Due to the ship's troubles however, he has decided to hold the party on the ship itself now, with the invitees being brought especially on the Mitsukawa-Maru as it lays off the coast.  While one tiger has already been prepared, the other is bit more troublesome: the ship's troubles led to one tiger cage being broken, and now that tiger is running free in two connected rooms in the hold. Terue is Hirokawa's maid, and she's on the ship too to take care of her boss' guests, but she comes across the dead body of one of them! She reports to her boss, but when they return to the place, the body is gone, and her boss is not really believing her. Hasuno and Iguchi however have reason to believe Terue might be right, as the victim was a reporter on the trail of a serial killer, who might be one of the other guests, and they start poking around and looking for the body. This is by far the longest story of the bunch, offering a closed circle mystery with unique elements like a friggin' tiger in the hold, but I feel this story was way longer than it needed to be, and even felt a bit tiring after a while. Hasuno and Iguchi are already aware of much of the background story by the time the story starts, so the reader is always at a disadvantage, and unfortunately, this story has no floorplan even though the characters move around a lot on the ship. Eventually, Hasuno deduces who the murderer is based on the actions they took, but to be honest, the whodunnit wasn't nearly as impressive as the whydunnit. At least, the whydunnit regarding the direct motive for the second death and the implications of that death was absolutely great, and I would perhaps have preferred a story focusing solely on that.

Houseki Dorobou to Okidokei ("A Jewel Thief and the Table Clock") brings up back to the Dutch table clock from the first story. Iguchi receives a letter from the (son of the) previous owner of the clock, who hopes to buy back the clock. Iguchi has two major problems: due to the conclusion of the first story, Iguchi is still in possession of the clock, even though it belongs to Kaemon and two: the clock was stolen. He had kept it wrapped up in a cloth in the bedroom, but for some reason someone stole the clock, and just the clock, with nothing else in the bedroom being disturbed. This was also only one theft in a series of thefts among friends of his wife: several rubies have been stolen, but all under nearly impossible circumstances: for example, one friend had a bracelet with a ruby embedded in it, and hidden it within an orange cloth, put in a box with many other wrapped up cloths, but the thief managed to steal only the one with the bracelet in it, without opening the other cloths. In another theft, the thief stole a ruby which had been put on a dress, but there had been four identical dresses, with the other three having very well made imitations, so how could the thief so quickly found the real ruby, not even having to touch the other three dresses? While the tricks behind each of these cases is fairly simple, I do like how some of them are connected, leading to some nice synergy moments: the explanation for the ruby on the dress theft for example is pretty clever on its own, but it also gives a great explanation for how the thief managed to find the antique clock in Iguchi's home. While I don't really think this is a very memorable story (I think I had expected it to connect a bit more strongly to the previous stories), it's an okay one, and it also leads directly into the events of Salome's Guillotine.

Overall though, I did really enjoy Tokeidorobou to Akunin. I think Yuuki Haruo especially excels in coming up with cool motives that not only are memorable, but they also often naturally lead to the core mysteries of howdunnit or whodunnit. I already noticed that in Salome's Guillotine, but as a short story collection, you of course see more instances of that here. The banter between Hasuno and Iguchi is also fun, and while some of the stories can become a bit darker, there is usually a slight comedic tone to them (the two stories told from the maid's POV for example have some funny moments where they lament having to work for their employers). So another recommended read! I should probably read the first book too...

"Labyrinths: Selected Stories & Other Writings"

I wasn't aware the full title of this book was so long until I started writing this review...

Shizuku is a detective. At least, she plays one, in the virtual reality MMORPG Alfheim Online. As "Spica", she has her own detective agency, with even her very own Watson (her childhood friend, and narrator Endou). In reality, she has never ever taken a case, and the two just hang out in the office every day after school, but don't say that out loud in front of Spica. One day, the narrator finds a mysterious object in his inventory: he has no memories of ever picking up such an item, so how could it have been added to his inventory? When the two take a look at the diary, they realize they have in their possession an impossible object. For this diary purports to be written by a player of the VR MMORPG Sword Art Online, and written within SAO. Which is impossible: Sword Art Online was the infamous brainchild of Kayaba Akihiko, who made a revolutionary virtual game system with a helmet that stimulates all 5 senses, but when the game launched, the players found themselves trapped inside Sword Art Online by Kayaba. Players were unable to log out and they were told that if they died in-game, the helmet would also kill them in real-life, which would also happen if someone tried to forcibly log them out by messing with the hardware. In the end, players did manage to beat the game and escape, but many of the players had suffered deaths in the meantime. After the game was beaten, most of the data of Sword Art Online and all the records of what happened within the world was deleted however. The in-game world was completely lost, though the very basics of the system survived, allowing the creation of the (safer) Alfheim Online as a spiritual successor. So how could Spica and the narrator now have a diary that was written by one of the players in Sword Art Online during that period, and how did it appear in Alfheim Online?

The diary itself is written by a player called Jason, who is the leader of a party called the Argonauts. While they are fairly powerful, they are not strong enough to be leading the attempt to clear all 100 floors of Sword Art Online. The Argonauts however do fulfill an important role. Because the frontline parties try to clear each floor as quickly as possible, they are not able to explore each floor completely. Parties like the Argonauts are active a few floors behind the frontline parties and help explore every corner of each floor, because they might find hidden equipment, items or hints that may help the frontline parties. It is during one of these exploration missions Jason, and his comrades Orpheus, Hercules, Asklepios, Atalanta and Caenis find themselves transported in an underground labyrinth. While they explore the place, they are suddenly attacked by a menacing Blind Minotaur. While the party display fantastic teamwork, they soon realize that the Blind Minotaur is faaaaar more powerful than they are, and they are hardly able to chip off even a little of his hit points. As a hopeless battle, all they can do is flee, and then soon learn that they are safe if they manage to stay inside one of the few rooms in the labyrinth and keep the door closed, as the Minotaur is not able to get inside "uninvited." The Argonauts try to find a way out, but run into a different party who just made it here: the Legendary Heroes consist of Arthur, Evelyn, Rocky, Azrael, Mark and Omega, but unlike the Argonauts, it's clear this party isn't really a team, and their whole strategy revolves around Arthur alone. The two parties don't really trust each other, and decide to try to find a way out on their own, while avoiding the Blind Minotaur, who seems to have a set pattern of appearing from an underground lair once in a while and then return again. However, the Argonauts are later contacted by the Legendary Heroes with shocking news: it appears Arthur had gone out into the labyrinth on his own during the night, and was killed by the Blind Minotaur (something his party members can see "on screen" happen, as you can always check a party member's hit points and status). There are however suspicious points to Arthur's death, as why did he sneak out in the night and why would he try to take on the Minotaur alone? The two parties agree to find a way out together, and they suspect this dungeon isn't about beating the Blind Minotaur, but finding some kind of secret that solves the dungeon, but while they are trying, more and more people are killed, and they soon start to realize some of these deaths weren't commited by the Minotaur, but one of their own. But why?

As long as it's a mystery, I'm interested, so I occasionally consume mystery media based on IPs I don't even know or have ever seen/read. In the past I have for example discussed the Fate/Grand Order mystery novels by Van Madoy, even though I don't play the game and have still not ever played any of the Fate games or seen any of the anime series. I also originally had no interest in watching Oppenheimer, until someone told me you could totally watch it as a mystery film, and... he was right. So when I learned Konno Tenryuu had written a mystery novel for Sword Art Online, the franchise based on the light novels by Kawahara Reki. I was immediately interested, even though I have not seen or read the series. Yes, I know it's really popular, but I'm from the generation where "an isekai series of a boy having to clear floors to beat a RPG-like world" equals Mashin Eiyuuden Wataru. Anyway, I have read a few of Konno's books too, many of them dealing with fantasy elements, and I like his work, so I knew I wanted to read Sword Art Online Alternative: Mystery Labyrinth - Meikyuukan no Satsujin (2023), or as the cover also says: Murder in the Labyrinth Pavillion.

I can at least say that even with zero prior knowledge of the Sword Art Online franchise, this was pretty accessible. It is, as far as I know, not directly connected to any events from the series, and is mostly a standalone story, though it is set after the original Sword Art Online was beaten, so the first series/book. The mystery plays at two levels, the series of murders that occur in the Labyrinth Pavillion dungeon and the parties' attempts at finding an exit out of the maze, and a meta-mystery where Spica and the narrator try to figure out how this diary could've made it out of Sword Art Online, a world that has been destroyed, and into Alfheim Online.

The murders in the Labyrinth Pavillion are of course the meat of the mystery and I found it highly entertaining. Konno does a great job at actually incorporating the game-element of Sword Art Online to create highly original mysteries, that are truly only possible in such a setting. For example, we have characters witnessing a murder and learning the exact time of a death not because they seeing the death with their own eyes, but because they can see their party member's HP bar dropping in the party member status screen: where else could you ever see such a way to establish a time of death and alibis for the suspects!? Other cool things are how there are no corpses in the world of Sword Art Online, with the player's body simply disappearing from the game world if they are killed, though they do leave whatever they have equiped at the time, again opening up possibilities for shenanigans as the murderer doesn't have to deal with hiding bodies. As a closed circle setting, the Labyrinth Pavillion is also interesting, as the rules of the game make it a place you can't easily get in or out to, making it a very convincing confined location. Add in the rules of how many people can stay in a room and how you have to invite people inside, and the characteristics of the Blind Minotaur (the players slowly learn its attack and reaction patterns through their various encounters, which again tells them how the Minotaur could've been used to faciliate the murders) and you end up with a novel that is just fun to read because you're constantly confronted with new ways to present a mystery due to the unique setting. Clever things are done here, and the fact the Blind Minotaur (a force of nature/a game enemy) is used as a "murder weapon" is of course also really interesting. The motive for the murders is also rather unique to this series: while I don't think it's completely convincing, I do think Konno did a great job at really making this a motive that works in Sword Art Online. The one thing that didn't really work for me was solution to beating the Labyrinth Pavillion: that part of the mystery is just too farfetched, and nobody would be ever able to solve such a puzzle...

Meanwhile, the meta-mystery at the Alfheim Online level is probably easier to guess, as Spica seems to know what the trick is from a very early stage and gives out hints. The answer might seem a bit predictable once you reach about the middle of the book, but overall, I think it provides a nice side-story to Sword Art Online, being completely seperate of the main story, but still firmly set within that world. It probably helps the book was based on an idea by series creator Kawahara, and also supervised by him!

So even without ever having seen any Sword Art Online, I can safely say Sword Art Online Alternative: Mystery Labyrinth - Meikyuukan no Satsujin is a fun mystery novel, that makes great use of its VR MMORPG setting to present a mystery with elements you won't find in other mystery novels. It is a book that fully utilizes the fact it is based on an existing IP, building on the story and rules of the franchise, yet at the same time is not at all dependent on the main story. It's really impressive what Konno managed to do here in that sense.
