The Man in the Mist

"Very few of us are what we seem."

"The Man in the Mist"

This will probably be the longest novel I'll read this year, being slightly longer than Asukabe Katsunori's Massatsu Goth Gods, which I reviewed two weeks ago. 

After the events that occured in the house of the wealthy Jewish financier François Dassault in 1978, Nadia Maugars, daughter of Inspector Maugars, and Yabuki Kakeru, a Japanese student studying in Paris and amateur detective, are invited to attend a dinner at the house. Other guests include Hannah Kauffman, a political theorist whose work interests Kakeru (yes, she's based on Hannah Arendt). While Nadia and Kakeru were deeply involved in solving the triple-locked-room murder at the Dassault residence, this is the first time they meet more of the family, as most of them were not present at the time the other case occured. Among then are Veronica Laurent, François' second wife, Sophie, François' daughter of his deceased first wife and Christian Hovora, François' friend and confidential secretary. Early in the evening however, François receives a phone call, with a voice telling him his daughter Sophie has been kidnapped and demanding a great sum of money as well as The Tear of Nicole, a family heirloom jewel. However, it turns out Sophie is... all safe at home. However, it doesn't take long for them to realize that the kidnapper must have taken Sara Lerouge, the daughter of Etienne, François' chauffeur. Sara and Sophie are the same age and have grown up together as the best of friends and it turns out Sara had been wearing Sophie's clothes today. While François does inform the kidnapper of his mistake, the kidnapper still demands the money and jewel, unless they want to see Sara dead, and François immediately assures the kidnapper he will comply, as both Etienne and Sara are dear to him too. The kidnapper demands that Nadia, a guest at the party, bring the money and the jewel, packed in a bag, to a certain place in Paris by a certain time, alone of course and without contacting the police. They realize that the kidnapper must somehow have visual knowledge of the people at the dinner party, but with little time to think, Nadia accepts her mission to transport the ransom money. 

Meanwhile, her father Inspector Maugars is called to investigate the murder of the headmistress of a Catholic school: the woman was found shot through the head in her office in the early evening. While there were no classes today, the school's girls choir had to rehearse for a recital in two weeks, so the doors of the school were left open to let the girls in and out. The police is wondering how the murderer got in and out the school: while a hooded figure was seen fleeing the school just as the students had finished their rehearsals and about to leave the school too, they can't establish a proper route for the murderer to get in, especially as the route that leads into the school via the back entrance was found "locked": some doors on this route were locked with a key that was found in the headmistress' office, meaning they were locked from the "inside". But why didn't the murderer just use that key to escape via the back exit route? During his investigation however, Maugars learns of a connection to the kidnapping going on at the Dassault house, but this connection only seems to confuse things even more in Kasai Kiyoshi's 2025 novel Yoru to Kiri no Yuukai, which has the French title Nuit et brouillard enlèvement on the cover, but we'll call it A Kidnapping into Night and Fog here.

And yes, that's a reference to the Nacht und Nebel decree. 

Yoru to Kiri no Yuukai is the eighth book in the Yabuki Kakeru series, which has a rather interesting publication history. After writing the first five-or-so stories as direct-to-novel publications, Kasai Kiyoshi would be serializing the newer stories in the series, usually taking a few years for each new book as he tends to have rather lengthy books. However, that doesn't mean all those stories actually got proper collected book releases. In some cases, it'd take years after a serialization for a story to actually get a proper standalone release. Yoru to Kiri no Yuukai is one of those cases: while the book is published in 2025 (making it eligible for all kinds of "2025" rankings), the original serializaiton of the book occured back in 2010, meaning it took 15 years for the publisher to decide to actually put the story out as a book. There are more examples of that in this series, like a story that's been in serialization since 2017, and another book that's been fully serialized and finished in 2015 but still hasn't been released as its own release.

Anyway,  Yoru to Kiri no Yuukai is directly linked to Tetsugakusha no Misshitsu, the fourth book in the series and actually the first one I read. I haven't even read that much of this series, but Tetsugakusha no Misshitsu is quite well-known for its triple-locked-room setup, so if you're like me and not particular about reading things in order, it's quite likely someone will start the series with that book. Anyway, while Yoru to Kiri no Yuukai is connected to Tetsugakusha no Misshitsu and features both familiar faces as well as similar themes, I wouldn't say it's necessary to read Tetsugakusha no Misshitsu first in order to understand Yoru to Kiri no Yuukai. On the other hand, and this is a Yabuki Kakeru series staple, Kasai doesn't mind spoiling his books. There is a developing storyline in these books, in which Kakeru is after a certain person, and author Kasai has no qualms at all at spoiling previous books, like explicitly saying who the murderer was in a previous adventure. So reader, beware.

The other reader warning is of course that other Yabuki Kakeru staple: the books being used as a device to have the characters talk about philosophy, politics and history. Like in Tetsugakusha no Misshitsu, this time themes of anti-semitism, nazism, authoritarianism and the denial of the holocaust play a major role in this story. Kakeru finds a very willing discussion partner in Hannah Kaufman, with whom he talks and talks and talks in this book, and I will once again gladly reveal I'm never a big fan of these segments as I'm not as interested in the philosophical discussions like Kakeru is, whether it's on nazism this time or nuclear plants in another book. I really enjoy the mystery parts though, so when I hit another one of those lengthy philosophical discussions it makes me even more aware how I don't really enjoy them at all. The discussions also come at the weirdest moments: one occurs after Nadia returns from dropping off the ransom money/jewel and returns to the Dassault home. You'd think she has plenty to discuss with Kakeru about how the dropoff went and all of that and worrying about the fate of poor Sara as she still hasn't been returned yet, but now, we have Kakeru and Mrs. Kaufman talking about deniers of the Holocaust.

So let's talk about the mystery plot of the book, because that part I really enjoyed! We're dealing with a two-part mystery this time, one concerning a kidnapping of a girl that's gone wrong, and a "conventional" murder that occured in a school, both crimes happening around the same time. Of course, the reader can guess there's something that links these two crimes together, but fortunately, this connection is revealed relatively early on, with the rest of the mystery focusing more on the contradictions and further mysteries and questions that arise when you arrive at the realization of the connection between the two cases.

Because "solving" a kidnapping case is different from simply identifying a murderer in a murder case, kidnapping cases in puzzle plot mysteries tend to use similar ideas, often playing with the concept of "there's another crime/event going on that's being hidden via the kidnapping case" and in essence, I wouldn't say Yoru to Kiri no Yuukai provides a paradigm shift, but Kasai does manage to add some surprises the twists that seem predictable at first. The whole ransom dropoff sequence with Nadia follows familiar beats, with Nadia being given little time to go from location A to B, to C per the kidnapper's orders, but there are minor mysteries along the way for Nadia and the reader to solve. Furthermore, Kasai manages to hide some really good clues in this segment too that only become relevant further in the book. Meanwhile, the murder on the headmistresss in the school seems a conventional murder investigation, with most of the mystery revolving around who could've gained access into the school without being seen, and the mystery of why the murderer would choose to leave through the front door, instead of how they got in. This part is a bit technical and mechnical at times, with time tables about where everyone in the school was at what time and where keys were etc., but on the whole, it's a fairly solid puzzle. 

The book however becomes really interesting once the hostage is found: newly obtained evidence lead to the shocking conclusion both the kidnapping and the school murder were connected all along, but it's this very conclusion that adds confusion to the investigation: things that seemed possible and simple when the two incidents were seen as seperate events, now become impossible and unexplicable once they are connected. Kakeru in particular finds the "form" the two cases take on after their connection is discovered frustating, as he knows that if these cases are really connected, they shouldn't have ended up the way they did. I have only read four of the Yabuki Kakeru books now, but of those books, I do think this book does the best job at showing how Kakeru's interest in phenomenology is used to solve these mysteries, with him analyzing the whole event as is and then realizing it doesn't make sense. All the questions that bug Kakeru are of course answered in the end by him, but one good thing of these books is that while Kakeru always finds the final, true solution, the other recurring characters often come up with very good theories themselves. Narrator Nadia is always just barely one step behind Kakeru, and even a character like Jean-Paul, who could easily just have been the "Velie" to Inspector Maugar's Inspector Queen, is a bright detective with plenty of good suggestions. The book juggles a few false solutions in front of the reader, and while I do think it's a shame the reader can easily intuitively guess who the murderer is without going through the whole chain of clues, I do like the mystery as plotted by Kasai here, and the themes are worked well into the mystery.

So while I am still not very charmed by the long philosphical discussions in this series, I did like Yoru to Kiri no Yuukai a lot, being a mystery novel that does a good take on the trope of the kidnapping case in a murder mystery, and one that especially does a good thematic exploration into certain tropes of the mystery genre and using that exploration to set-up a great route to the truth for Kakeru. The who and how might be a bit easy to guess, but the construction of the mystery is honestly done well enough for me to not care too much about that actually. I don't know whether I'd recommend this book as one's first Yabuki Kakeru book, because you'll get spoiled on the lore of the series, regarding both small and big issues, and yet, I do have to say I think the core mystery as it is set-up, and the way we see Kakeru solve this case, would really work well as a series introduction. Perhaps in a different universe, this mystery plot would've been used for the first book.

The Big Four

"From the ashes of this world I will build a better one. Go forth, my horsemen and let chaos cleanse the world."

"X-Men The Animated Series"

Hmm, funny how a lot of the reviews posted this winter are set in the summer...

After a murder case that involved her own friends, Nadia Maugars, daughter of Inspector Maugars, still doesn't know quite how to move on, especially as in contrast, Yabuki Kakeru, a Japanese student who studies philosophy in Paris who tutors her in Japanese, seems eerily cold and untouched by the incident. Kakeru is in fact far more interested in Nadia's friendship with Giselle Rochefort, daughter of August Rochefort, one of the major names in the financial world of southern France. Giselle is studying history under the tutelage of Charles Sylvain: Kakeru wants to view certain documents involving the Cathars, which Charles can provide him. Kakeru and Nadia learn Giselle will be staying at her father's holiday home in the south of France this insanely hot summer, as her father is trying to get a nuclear power plant in that region. Charles will also be there due to an excavation where they expect to find objects related to the Cathars, and others are also expected to be there, like Giselle's boyfriend Julian, a nuclear researcher connected to the Rochefort nuclear plant, and his sister Simone, a teacher and activist. Kakeru and Nadia also travel to the same village, as Jean-Paul Barbes, a subordinate of Nadia's father, hails from there. Everyone is hanging around the holiday home of the Rocheforts, when a loud crash surprises everyone. They gather in front of the second floor room where the noise came from, which they find locked from the inside. Kakeru enters the room via the garden and outside balcony, and inside they find the murdered body of Fest, a visiting antiquarian. For some reason, Fest was knocked out on the head and then an arrow was stabbed in his chest, with the bow and arrow being part of the room's decoration. When Kakeru finds Fest had first been knocked out with an object with one of the biblical Johns on it, and he also later learns a white horse belonging to the Rocheforts was killed too at the same time, he realizes what is going on: this murder was styled after the Book of Revelation: the segment regarding the first horseman of the Apocalypse says: "A white horse appears, whose crowned rider has a bow with which to conquer." But that begs the question: does this mean three other people will be murdered too, and why commit a murder like this? Meanwhile, Kakeru has more things to think of, as an attempt on his life has been made due to his interference in the previous incident. Can he solve all of these problems in Kasai Kiyoshi's Summer Apocalypse (1981)?

The first novel by mystery author, critic and philosopher Kasai featuring Yabuki Kakeru I read was back in 2015, but after reading Tetsugakusha no Misshitsu ("A Locked Room for Philosophers", 1992), it took me about ten years to return to that series with Oedipus Shoukougun ("Oedipus Syndrome", 2002), which I read last year. Perhaps it's therefore surprising I'm reading another entry in this series so soon, but what shouldn't surprise frequent readers is that I once again read the series completely out of order. After reading the fourth and then the fifth novel, I decided to go back to the second novel: Summer Apocalypse. To be completely honest, the Yabuki Kakeru is really not the best series to read out of order: Kasai really likes to start each new book with a recap of the events of the previous book and he doesn't mind spoiling major events, including the identity of the murderers, in these prologues. That holds even for this second book, which freely spoils the identity of the murderer of the first book (Bye Bye Angel), which I haven't read yet. The prologue also builds directly on the ending of the previous book, with shocking incidents happening to Nadia and Kakeru due to what happened in Bye Bye Angel. This storyline is also of importance later in the book, as Kakeru remains invested in the aftermath of what happened in the first book throughout his investigations in this second book. Why did I start with this book then, you might ask. Well, I wasn't really planning to read "a Yabuki Kakeru" novel when this book found its way on my reading pile to be honest. I had in fact been looking for mystery fiction themed after the Book of Revelation and the Apocalypse, and this book was one that was mentioned a lot in Japanese sources (in the past, I also reviewed the manga Father Sakura which had a story involving the Apocalypse too).

My previous experience with this series already taught me Kasai likes to write long novels, and that likes to use them as vehicles to talk about philosophy, history and other topics that might interest him, and to be honest, I have often felt he went too far with that for my taste, having to wade through pages of characters discussing philosophy while they're in imminent danger of being murdered. Fortunately for me (your mileage may vary), this book is a bit shorter than the previous two novels I read, and therefore it stays a bit more focused on the core mystery plot, though there's still plenty of talk about Catharism and the characters' stances regarding art, nuclear plants and more of that. Ironically, the one thing I did hope he'd write more extensively about, that being the Book of Revelation and the meaning of the Apocalypse, is surprisingly less of an important theme, and while they of course do discuss the topic over the course, I do have to say I was a bit disappointed it never went as deep as I hoped it'd go: I'd loved to have read more about the historical background or for example interpretations of the Book of Revelation.

Nonetheless, a mystery novel about a series of murders modelled after the Four Horsemen of the Apocalypse is of course an exciting idea: each time a murder is commited, a victim is killed with an object invoking the respective horseman, and you might want to avoid this book if you love horses, because yep, horses are also murdered each time. Many of the murders have slightly impossible aspects to them too, at least, if you assume the murderer is someone in the main cast of characters, as each time, all or at least most of them seem to have fairly good alibis for the murders. For the first murder for example, most characters arrive in front of the room very soon after they hear the noise made by the murderer, making it unlikely any of them had been inside the room seconds ago: with the door locked from inside, the murderer would have needed to take the long way around via the balcony and the garden to get back inside. To be honest, I was not a big fan of the solution to this quasi locked room: the solution is one of the type that can work in some situations, but here I think the hinting to the existence of such a thing seemed a bit too weak, though I do like how it tied to the horseman imagery. In fact, I think the manner in which Kasai integrated the Horseman themes into the mystery is the most interesting part: they fit very well with the motive of the mastermind behind these murders and the props indicated in each of the verses are used in interesting manners to faciliate said murders. Obviously, 'dressing up' each murder to correspond with the Horseman verses is partially done to act as misdirection, and I think that is executed really well here, but Kasai does go beyond just using it as misdirection, giving a proper thematical (character driven) reason to have these murders indicate the end of times.

What I also liked about Summer Apocalypse is that Kasai has more surprises beyond the allusions to the Apocalypse: the way the murders are ultimately explained is done in a rather surprising way, and while at first you might be wondering why it is done in this particular way, it all does come together in the end, and mystery-wise, I think this was an interesting approach by Kasai. I can't talk too much about this unfortunately, but it's a theme I generally do like in mystery novels, and while you see it relatively often nowadays, it would have been far less common in 1981, and in that sense, Summer Apocalypse still feels very modern despite it predating shin honkaku novels.

While Summer Apocalypse didn't go as deep in the topic of the Apocalypse and the Four Horsemen as I had initially hoped, I still think this is a fine example of a mitate (themed) murder mystery: murders committed in a way to allude to the Book of Revelation is just a really exciting theme, and Kasai manages to use the theme in a very clever way that is also deeply connected to what moves the characters in this novel. While I wasn't a fan of all the individual murders, the Apocalypse glue did make this a fun mystery to read, and in terms of the mystery plot, page count and Kasai talking about philosophy and other topics, this was definitely the one book that managed to feel like it balanced these elements the best, at least, it fitted my own personal preference much better than for example Oedipus Shoukougun, which felt much slower and meandering. At this point, it is likely I will also read Bye Bye Angel one day, but beyond that, I feel like I'm not really reading these books because I am invested in the story and characters of this series, and I'll probably just return to it if one of the books happen to be about a theme I want to read about, rather than me wanting to read a Yabuki Kakeru novel.

The Red Bull

"Come along, my friend! You want to see the Bull's Head, yes?" 

"Broken Sword: Shadow of the Templars"

While this post won't be posted until 2024, I read this book in 2023. I tend to prefer shorter books, but I think read like three or four of these 1000+ pages books in just a few months last year...

After a strange arson incident at the Pasteur Laboratory, Nadia Maugars learns via her father Inspector Maugars and his subordinate that her old friend François Duval, who works at the laboratory, is back in Paris. They lost contact after he moved abroad, where he researches viruses. His return however is not one to be happy about: he had to return to Paris, because he is suffering from a newly discovered virus, which he had been researching and for which there is no treatment yet. Nadia visits François at the hospital, and he asks her to bring a report he had been working on regarding the new virus to his co-worker Pierre Madocq, who is currently in Athens. The thing is highly confidential, so he wants her to personally hand it to Madocq and he also gives her enough money to buy tickets tomorrow, and to stay in Greece for a while after she's done so she can have fun there. Nadia brings her friend Yabuki Kakeru, a Japanese student of philosophy and her tutor in Japanese, along, because she fears his life is in danger in Paris, as his arch-nemesis is in Paris. When they arrive in Athens, Nadia is surprised to learn Madocq is not there, but on Minotaur Island, a small private island off the coast of Crete. She's sent off to Crete ahead, while Kakeru has to make a phone call, and at Crete, she runs into another old friend: Constant, who disappeared a few years ago after getting too involved with the extreme left-wing student movement, but has now become a published philosopher. Nadia convices him to come along too, as Kakeru is not here now. When Nadia arrives at the village near Minotaur Island, she learns there are more people slated to go to Minotaur Island, including a doctor from Sweden and a few Americans, who are all invited by a "Laurence Bloom", even though the island is the property of one Paul Alexander, of the pharmaceutical company Biocross. On the day Nadia and the others are to arrive at the island however, a fellow guest of Nadia's hotel is found dead, having dropped off a cliff. The victim's name Dedalus reminds Nadia not only of Joyce's Ulyesses, but also the Deadalus myth (even though it's Icarus who fell), and it already gives her a bad feeling. Meanwhile, Kakeru has also caught up, but Kakeru told her to pretend to not know her, as for some reason, he's pretending to be the assistant of one of the other invited guests, a philosopher. When they arrive at the Deadalus House on Minotaur Island, they find a grand manor built in the style of a Minoan palace, with a big courtyard with ten bull statues. Nadia manages to hand the report to Madocq, who acts as the host as neither "Laurence Bloom" nor Alexander are present yet, but she quickly realizes the other guests have all been invited her for a secret reason, which nobody wants to tell her about. As the boat back to Crete won't go until the following day, she and Constant are offered to stay for the night too, but after dinner, one of the guests is found dead: the man seemingly fell of the balustrade on the third floor, falling right on top of the horns of one of the bull statues below in the courtyard. It could be an accident, they think, but when they discover one person on the island has taken off in the island's only boat and they learn the phone line's been cut, they suddenly realize this is really close to And Then There Were None. And indeed, one by one, people are killed on the island, but by whom and why? That is the question in Kasai Kiyoshi's Oedipus Shoukougun ("Oedipus Syndrome", 2002) 

It's been many years since I read Tetsugakusha no Misshitsu ("A Locked Room for Philosophers", 1992) by mystery author, critic and philosopher Kasai Kiyoshi. That was the fourth book in the Yabuki Kakeru series, starring Yabuki Kakeru, a Japanese student of philosophy who solves baffling crimes and mysteries through phenomenology, i.e. the analysis of structures of experience and conciousness and who because of that, usually doesn't start solving a case until the end because he needs to see the whole structure in order to analyse it. It was also the first time I read a fiction book by Kasai (I had read a few of his critical works on mystery fiction), so it took quite a while for me to get started on my second. Interesting to note it also took Kasai ten years to follow up on Tetsugakusha no Misshitsu with Oedipus Shoukougun. I didn't pick Oedipus Shoukougun because I wanted to read things in order or anything like that by the way (I still haven't read the first three books in this series). In fact, I wasn't even planning to read a Yabuki Kakeru novel in particular. I had been looking for Japanese mystery novels inspired by Greek mythology, so I ended up finding this one. Like the previous book though, Oedipus Shoukougun seems to be written really like the fifth installment of an on-going story, and especially in the opening chapters there are segments that are probably spoilers for earlier adventures.

One thing to mention right away however is that 1) this book is long (more than 1000 pages), and that 2) Kasai likes to write about a lot of topics that are not directly related to the mystery plot. Depending on how much you can stand the latter, this can be a very interesting book, or an extremely long-winded one. I personally tend to fall in the latter category, and I certainly didn't enjoy the book as much as I perhaps could have, because there's just so much chatter about topics that didn't really interest me, but your mileage may vary there. In a way, it's very similar to the writing style Shimada Souji also has in his Mitarai Kiyoshi novels after the first few ones or something like Alcatraz Gensou, where he just starts writing about whatever topic that happens to be interesting him at the moment in a book, making them bloated works. In Oedipus Shoukougun, Kasai's pet peeve is of course philosophy, and characters will sometimes have extended discussions on philosophy. It's a topic that doesn't interest me personally, so I found these parts extremely tedious, but I guess some people will like it. Still, I think some of these discussions don't really make sense. There's a part where the closed circle situation on the island has been going on for a while, and they fear there's a murderer on the island. While some of them go search the house to see if it's safe inside, two others remain outside to wait for the clear sign. And what do these two do? They have a philosophical discussion. Topics range from sex to why a society condems murder, and there are also other discussions regarding the gay community and other topics, but I didn't really like the constant derailing that much, especially as they are only tangentially relevant to the core mystery plot (and certainly didn't need to take up such a large part of the narrative).

Because of the above, it also takes ages for the plot to finally move to Minotaur Island and to have the And Then There Were None-inspired plot to be set in motion (I have books that were shorter than the whole first section of Oedipus Shoukougun). Oh, for some reason this book also makes numerous references to how their situation resembles "a certain famous mystery author by a British novelist" and even spoils that book, but it never actually says the title. The same with the Ulysses references. Anyway, once it gets started, the plot becomes a bit smoother. After the first death, the caretaker disappears from the island with the boat... but is surprised by the storm raging outside, which overturns the boat. Which effectively traps everyone here on the island. But the following day, the murders continue, with more people being pushed down into the courtyard and other attacks being made on people. There's even a simple locked room mystery near the end, though that gets resolved pretty soon after it pops up. Overall though, the murders are fairly straightforward, and it's more a question of "Who could've committed these murders alibi-wise ?" For all the set-up regarding the Minosian palace, bull statues and other references to Greek mythology though, it's a bit disappointing these elements weren't played stronger, as the few links there are, are rather weak and not extremely important to the plot. 

There are clever parts in the mystery plot but I think they kinda get buried by the amount of other things going and being told to the reader, and overall, I thought that as a closed circle murder mystery, Oedipus Shoukougun was just okay, with the potential for being a lot better had it been trimmed down and been focused more. A person obtaining a perfect alibi because of what he saw was done really well for example, and while not every part of the motive of the murderer worked for me, I think one part, the specific reason for why the closed circle was created, was an inspired move: it invokes a certain famous book perhaps, but here it is implemented in a far more natural way in-universe. Some of the clues pointing to the murderer were quite subtle too, allowing for Queen-like deductions, but I do think that due to few likeable characters and the constant derailing because Kasai wants to talk about something, the book overall feels tedious as a mystery novel, especially considering the enormous page count. If you just look at the mystery plot itself, it's a decently constructed story, with a few memorable moments, but it's not mind-blowing or anything.

For people who like their mystery novels to be a bit more pure literature-like though, I guess Oedipus Shoukougun might be interesting? It will certain tick those boxes better than a "straightforward" mystery novel. For me, this mode doesn't really work that well, and just looking at the core mystery plot, it's a good closed circle mystery with some genuinely good ideas, but in its current form, it just doesn't quite manage to capture me. So a book that will choose its readers, I think.

Death Comes as the End

"It's our problem - free philosophy Hakuna Matata!"

"The Lion King"

It took me almost two years to work up the courage / spirit to go through today's book. The prologue was just too dense to get through. Of course, when I finally got past the prologue, it turned out to be not nearly as bad as I had feared. 

A distressed call screaming murder brings the police to the doors of the mansion owned by the wealthy Jewish financier François Dassault. Dassault however refuses to let the local cops inside and uses his connections to get Inspector Maugars in his house, who will hopefully help hush up what Dassault calls an unfortunate lethal accident that happened on his premises. One of Dassault's guests tripped and hit his head on the stone floor, it seems at first sight, but when Inspector Maugars discovers a knife wound in the dead man's back and a broken knife with the SS emblem on it, the case turns into a murder case. And a screwy one too. For one, it seems that Dassault's guest was not a voluntary guests, as the lack of luggage, the bare minimum of furniture in the room and the locks on the door suggest. And even more crazy is that after questioning all those in the house, it seems the man was stabbed in a triple locked space: (1) the third floor room in which the victim was discovered was locked from the outside, the third floor can only be reached from the second floor (which also houses the safe with the room's key), and (2) the staircase to the second floor was under constant watch by several witnesses on the ground floor and finally, (3) the only exit out of the mansion was also being watched. And the case seems to be connected to a group of Yewish people who survived the concentration camps... A most difficult situation, but Yabuki Kakeru (friend of the Inspector's daughter Nadia) is convinced he can bring light to the case with his phenomenology in Kasai Kiyoshi's Tetsugakusha no Misshitsu ("A Locked Room for Philosophers", 1992)

Tetsugakusha no Misshitsu is the fourth book starring Yabuki Kakeru, a Japanese student of philosophy who solves baffling crimes and mysteries through phenomenology, i.e. the analysis of structures of experience and conciousness. It is worth noting that Tetsugakusha no Misshitsu was published almost ten years after the third entry in the series, and while I have not read any of the other novels, it is said that Tetsugakusha no Misshitsu is a turning point for the series with a slightly different tone. Oh, and the long period between the third and fourth book certainly didn't stop Kasai from starting Tetsugakusha no Misshitsu with a long prologue where Kakeru and Nadia talk in detail about their previous adventure, including delicious spoilers, and discuss a bit of philosophy, so Reader Be Warned: the first sixty pages of this book can be difficult to get through.

But then again, what is sixty pages of a story that consists of 1100 pages spread over two volumes? It's certainly not the longest detective I've read (hello Jinroujou no Kyoufu and Ankokukan no Satsujin), but short, it is not.

The triple locked room murder happens early in the story and is great. It has the allure of one of those matryoshka dolls, with a locked room in a locked room in a locked room and Kasai adds enough twists and turns and fake solutions to the plot to keep the locked room mystery entertaining. Especially the way in which series detective Yabuki Kakeru manages to use the Amazing Powers of Philosophy to solve the crime is fantastic and like most of the best locked room murders: the solution itself is actually amazingly simple. And as if that wasn't enough, the story features another triple locked space mystery, one that happened in the past in a concentration camp. While the solution to this past murder is not nearly as elegant as that of the first one, these two mysteries do keep Tetsugakusha no Misshitsu going at a good pace for a fairly good time.

A fairly good time, I stress, because I have to be honest, I didn't enjoy all of the book(s). While this was the first novel by Kasai Kiyoshi I have read, this was certainly not my first encounter with him. I think that anybody who does any serious research on Japanese detective fiction will come across his name very early in the process, as he is also the author of a seminal series of books on the history of Japanese detective fiction and basically impossible not to know if you want to research Japanese detective fiction through the fields of sociology, philosphy and literary history and even formalism. So this might be my first meeting with series detective Yabuki Kakeru, I have been familiar with Kasai Kiyoshi and his thoughts on detective fiction for a good six, seven years now and we haven't always been the best of friends. I have the same with Tetsugakusha no Misshitsu.

There are quite some discussions on philosophy in this story, partly because Kakeru is in fact an international student in France to research philosophy, but an important philosopher who is Martin Heidegger in all but name also plays an indirect role in the plot and sometimes the characters start discussing the meaning of death and Dasein for a lot of pages and while I understand some do love philosophy, it's just not a field of interest to me. Especially not because I have read a lot of Kasai's ideas on philosophy in his academic works on detective fiction (the points he discusses in Tetsugakusha no Misshitsu will be very familiar to those who have read Kasai's Tantei Shousetsu Ron books). That said, I can imagine that someone with an interest in philosophy enjoying the discussions. I for example loved it when Kyougoku Natsuhiko wrote about folklore studies on youkai in Ubume no Natsu, which others might have hated. At any rate, philosophy does play a part in the themes of Tetsugakusha no Misshitsu, as the title A Locked Room for Philosophers suggests, so it's not just pedantry like in Kokushikan Satsjin Jiken. But considering this is a 1100 page story, with quite some talk on a discussion I do not particular like, so you can imagine I did find it a bit tiring. Heck, I think the book could have been half the length it is now and still work. But mileage may vary.

The funny thing about series detective Yabuki Kakeru is that he uses philosophy (phenemonology) to solve crimes. Which means he usually needs to see the whole phenomenon if he actually wants to analyse it. And yes, that in turn means he usually can't solve a crime until all elements of a crime have revealed itself. Kakeru can explain serial killings, but he can't stop serial killings because his method involves analyzing the meaning and connections of the whole picture. Kindaichi Kousuke also has a nasty habit of not being able to save anyone until the end of a case, by the way.

If you asked me if I enjoyed Kasai's Tetsugakusha no Misshitsu, I'd say "Yes, but...". It is a locked room for philosophers, which I am not, but the core locked room mystery is indeed well constructed. I am not sure whether it helped that I was already quite familiar with Kasai's academic works though. At one hand, it was kinda reading the same story again, but on the other hand, it did make the philosophic talk a bit more easier to follow because I knew where Kasai was going to. I think I might read some of the earlier novels in the series (which are less taxing, I heard), but I don't think I will read any of the later novels, if they all follow the tale as told in Kasai's academic work on detective fiction.
