Uncivil War

"Avengers... assemble."

"Avenger: End Game"

So I will never forget that when I watched Avengers: End Game in theaters, just before Captain America said the line, a kid in the audience cried "Assemble!" just before Captain America could, kinda drowning him out...

Official crossovers between different mystery series from different authors are not non-existent, but they are certainly not common. And most of the time, you can guess that these crossovers will follow the familiar comic crossover pattern, which even people who don't read comics will be familiar with due to its usage in for example the Marvel Cinematic Universe: heroes first have a confrontation with each other due to a misunderstanding or shenanigans cooked up by the villain, and eventually the heroes work together to take the villain down together. But what if you had a crossover with various detectives who aren't series detectives? What if you had detectives with different powers (deduction methods) who would compete. Who would be the best one? That is the question in Nitadori Kei's Suiri Taisen ("The Great Deduction War", 2021), which also has the less interesting English title of Who is the Best One?. The grandfather of the two cousins Yamato and Meguru (the narrator) was a big fan of mystery fiction, and when he obtained a Christian relic, he saw his chance. He contacted several churches across the world and invited them to participate in a special game of wits, in which the winner would be awarded the relic. Yamato and Meguru were to help out with the game, but their grandfather passed away just before the game starts, meaning now they have to lead it together with the family attorney. What they had not expected however, was that the various churches across the world would send almost superhuman (or even non-human!) detectives to represent them in the big war for the relic. Yamato and Meguru had perhaps at best hoped for a Father Brown-esque person to participate in the mystery game their grandfather came up with, but instead, we have a detective who can detect lies just by listening to someone speaking, a detective with super-heightened senses who can see, smell, taste, hear and feel the smallest details, a detective who can "clock up" his brain to consider every possibility within seconds and there's even a detective AI! Who will be the greatest detective of them all when the game starts!?

Okay, this is one of those books that I basically bought based on the title alone, and a quick look at the blurb. Having detectives with different work methods duke it out sounds like an amazing premise, and whereas in series, you often end up with a foil detective who obviously isn't going to beat the series detective, or you have the crossover where "everybody has to win" at the end, having a single (standalone) work with different detectives, and giving them all a reason to want to win the game individually (because they are all hired to win the relic), sounds exciting, right? I had only read one other work by Nitadori before this one, Jojutsu Trick Tanpenshuu, which was a comedic book where each story featured a feat of narrative trickery, but with a much moodier cover and a more "serious" set-up, I was curious to see what Nitadori would do with the idea of a "war" between the detectives.

Though it takes a while before we get to the war! For the first half of the book is used to introduce the various detectives from the different countries, with all but one of the participants getting their own chapter/short story where we see them solve a case in their home country, using their own unique powers. The opening chapter for example introduces us to Charlotte, the "operator" of the AI Detective Judas, which can solve cases with its computing power, of course if and only if the correct and relevant data is entered in the program. Her case involves a rather interesting decapitation case inside a room which only one person had the key to, but it doesn't appear he is really the murderer, so how does this work out? This is a pretty clever locked room mystery, but it's not really realistic. I think the trick is brilliant actually, and like it a lot, but I hadn't really expected this trick in this book, and especially not as the opening story. I can imagine myself accepting it easier if this had been presented in a comic format or something like that, because I'm not sure whether this really works like this physically, and 'reading' the trick somehow feels less convincing than seeing it. The other introducing chapters are all relatively short, and usually revolve around a one-trick idea that is used to show off the different powers of the detectives. The Ukrainian detective Bogdan Korniyenko for example has "Clock Up" (no, he's not a Kamen Rider), meaning he can speed up his thought process and consider countless of theories and possibilities within a second (though this takes a physical and mental toll, of course). This not only means he can solve cases relatively fast, but he can also do things that normally would take hours and even smaller actions, like stumbling over something, could be avoided if he starts Clock Up to take the best actions "during" the fall. Maria from Japan has heightened senses, which is not super interesting because it basically only means she can find small clues normal people usually can't, while Brazilian Mattheus can detect someone lying with a 100% accuracy by listening to them. Each of their cases of course introduces an element that requires their specific powers to find certain clues or to make certain logical deductions, but I think that as a standalone story, the first one (AI Detective) is the most memorable, and the others are more "functional" than really memorable, so I'll not write more about them.

In the second half of the story, the detectives arrive in Hokkaido, where they are to participate in the game to win the relic, with the cousins Yamato and Meguru, and the attorney Yamakawa organizing the 'war for the relic', even though Yamato and Meguru don't really know what the game was their grandfather planned before his unexpected death: they only know the idea is that there'll be a battle of the wits between the detectives and that the winner will receive the relic. The detectives and the organizers are all staying in cottages in a snow-covered camp, divided in two sides by a river, but the snowfall is pretty heavy, covering large parts of the camp. The first day is just the arrival, but the following day, they find the attorney Yamakawa murdered in his room. It appears this is the game of wits, and the detectives are all eager to solve the murder of Yamakawa and obtain the relic for their employers. What follows is an entertaining back-and-forth of different theories about who the killer is and how the murderer managed to kill Yamakawa without leaving clear clues (like footprints in the snow). Each detective is intent on winning the relic, and because they all have different powers and don't work together, they all obtain different clues, which allows them to come up with different theories which of course point at different people. It reminded me a bit of Yamaguchi Masaya's The 13th Detective, which was originally a game book and at the start of the story, you can choose one out of three different partner detectives, who will lead you down a different path and allow you to find different clues (disclosure: I translated Yamaguchi Masaya's Death of the Living Dead). Here too you have different detectives competing, each holding on on clues only they have, with for example Mattheus being able to detect any person lying but of course not willing to share that information, or the AI Detective being able to make certain calculations no person can. Because the crime scene is on one side of a river, with an observed bridge, and some people staying in cottages on one side of the river and others on the other, there's also a nice "is it an impossible crime?" angle to it: if the murderer is one of the people staying on the side of the crime scene, how did they come up with an alibi (an impossible alibi [time] angle), and if the murderer was on the other side of the river, how did they make their way to the crime scene unseen (an impossible alibi [space] angle). This whole set-up is defnitely the best part of the book, with one case offering many solutions because everyone tackles it from a different angle, and while some solutions are a bit too simple, others are quite interesting and could've been used as "real" solutions too. And because we got the introductions of the abilities of the various detectives earlier, it also feels 'fair' in the sense we don't hear about Mattheus' lie detector ability midway.

Though I have to say, I was a bit disappointed not all the detectives' abilities are equal. An ability like having better senses, or have an AI do complicated calculations are still on the realistic side of things, and even a person being able to think faster is okay, but Mattheus can literally just sense people lying as if it were a mutant power, and a fifth detective introduced in the second half of the story has a power that is really far beyond anything realistic, so the balance is kinda off. The book is set in an, on the whole, realistic world, so having supernatural powers, rather than slightly better than normal human powers, felt a bit weird. The tone of the book is also a bit weird at times: it is not as blatantly funny as the other book by Nitadori I read (Jojutsu Trick Tanpenshuu), and most of the time definitely more serious, but there's also a lot of light-hearted banter, pop culture references and other comedic touches like the cheeky attitude the AI Detective has towards Charlotte, but it's not always funny, so like the detective powers, it sometimes felt like Nitadori didn't know exactly what the exact tone or setting of the story was supposed to be.

I have to admit though that when the battle for the relic has been fought and the war is over... the ending is not nearly as satisfying as the preceding parts. Of course, with all these detectives competing for the relic, the book needs to work towards a conclusion that gives everyone *something* and still resolve the matter of who gets the relic, but the final solution presented to the reader is not nearly as clever as some of the solutions presented earlier, and on the whole, it's not a solution I like in general. Sure, there were clues, but I have seen Nitadori use the same type of clues in this book and Jojutsu Trick Tanpenshuu in more convincing ways, so it was a bit disappointing to see a less impressing example used for the final solution. It's of course difficult to come up with different solutions for the different detectives, and a final solution to surpass those ones too, but the way it suddenly shifted towards this final solution was just too abrupt, and feels less polished compared to the much better build-up to this moment.

But despite a somewhat disappointing ending, I do like Suiri Taisen, as the parts introducing the detectives and having them compete each other is really fun. It's a book that worked because it was a standalone book though, because you really can't guess who will win and how, but I wouldn't mind seeing for example Bogdan Korniyenko return in his own book. Not all parts of the book are as good, so it's not a book I love unconditionally, but certainly worth a read!

The Reader is Warned

Caveat lector

I might be deceiving the reader about today's book's contents in this review without actually lying too. Or not. *dundundun*

I have read locked room mysteries with locked room lectures, I have read mysteries about a dying message with a dying message lecture, I have read mysteries about a perfect alibi with an alibi lecture, I have read mysteries with decapitated corpses with a decapitation lecture, but I have not yet read a mystery novel with narrative trickery or unreliable narrators that feature a lecture about narrative trickery. Today's book however comes close: Nitadori Kei's short story collection Jojutsu Trick Tanpenshuu ("A Collection of Short Stories With Narrative Trickery" 2018) is surprisingly open and up-front about the main gimmick of the stories in this collection. The book opens with a daring Challenge to the Reader and openly declares that each of the stories you are about to read, will feature some kind of narrative trickery aimed at the reader. The stories are all about some, usually light-hearted mystery to be solved, but at the same time, these stories are written in a way to deceive the reader in one way or another, making it impossible for them to solve the mystery. But a warned reader won't be fooled.... right?

I've been interested in this book ever since I first saw the very literal title and the cute cover. There have been many (excellent!) mystery novels that feature some kind of narrative trickery aimed at the reader themselves, but usually, this is kept a secret until the twist ending where it's suddenly revealed that even though the reader believed that something was X, it was actually Y. Never before have I seen a detective story advertise the fact that it's about to deceive the reader directly and then dare them to see through the trickery! Note that 'narrative trickery' is broader than just the 'unreliable narrator' trope. I think these stories are actually at their best when they don't feature an unreliable narrator who blatantly lies to the reader in the narration or intentionally omits crucial facts that pertain to the mystery. A good mystery story with a narrative trick uses its narration to make the reader assume a certain fact, without ever saying so in that many words. The reader should be tricked to believe some fact, for example that character A is a male while she's actually a female, but the narration should never blatantly lie about it. A good mystery story with narrative trickery is simply written very carefully and skilfully to make the reader mistakenly assume something, but never resorts to simple lies. Some people find the unreliable narrator or narrative trickery in general unfair in mystery fiction, but I don't agree: a well-written mystery story with narrative trickery is fair in the sense that the wrong assumptions are always made by the reader themselves, and nobody (narrator/author) explicitly told them lies.

What's also important is that the mystery plot should never only revolve around the truth behind this narrative trickery and I think that's where Jojutsu Trick Tanpenshuu especially shines. Each of the stories in this volume revolve around a core mystery plot, though usually fairly light-hearted. The reader can usually solve most of the mystery 'as usual', but the reader is also always led to mistakenly assume certain facts or circumstances, and that's what prevents the reader from making that one final step to solve the mystery completely: this is not the case for the characters in the story themselves, which is why they do manage to solve the mystery before the reader and that's also what makes these stories feel fair, because the stories are solvable as shown by the characters who don't make the same false assumptions like the reader.

The collection opens with Chanto Nagasu Kamisama ("The God Who Makes Sure to Flush"), which is set at a small office. One of the toilets in the women's room upstairs has been clogged and the repair man has already been called, when the people at the office find out the toilet has now been unclogged. But the strange thing is: nobody at the office will admit to the fact they unclogged the toilet. But why would anyone lie about it, and why not just wait for the repair man who had been called already? What deepens the mystery is the fact there were witnesses outside in the corridor, so nobody could've brought all the necessary cleaning tools from the floor below to the bathroom without being seen, and yet that's what happened. A very fun opening story: the mystery of finding the 'culprit' who cleaned the bathroom is so wonderfully silly yet mundane. The motive of the culprit to remain silent about the act ties wonderfully to the narrative trickery aimed at the reader, who is expertly led to believe certain circumstances which makes the case harder to solve for them, but the characters in-universe quickly figure out who did it and why. The story's an excellent showcase for the narrative trickery employed in the book, for any assumptions about that made are entirely on the head of the reader.

The second story is relatively easier to solve: Senaka Awase no Koibito ("Lovers Back to Back") juggles between two narratives. At one hand, we follow Horiki Hikaru, a second-year college student who one day stumbles upon the SNS of a certain 'drizzle', the username of a girl called Hiramatsu Shiori. Hikaru loves the photographs and the interesting comments she posts on SNS and he slowly starts to become interested in the person behind the pictures. Surprisingly, he starts to recognize the backgrounds of the photographs however and comes to the realization that Hiramatsu Shiori is actually a student at the same university. Harboring feelings for her, he starts to look for her. Meanwhile, we also follow the story of Hiramatsu Shiori, an introverted member of the university's Photography Club, who has fallen in love with a kind senior student whom she doesn't know personally, but has seen helping other people around campus. She eventually learns the name of this student: Horiki Hikaru, brother of a fellow member of the club. The two come closer, when an incident occurs at the Photography Club: someone has switched the filters in the darkroom, ruining the photographs of the club president and both Shiori and Hikari get involved in this case. This one was the easiest case to solve in this collection, as it revolves around a certain narrative trick that is seen relatively often (the first story in comparison was really original), but the clewing in this story is also well-done, with a few lines of dialogue that should allow the reader to escape the misdirection if they hadn't caught on already.

Tojirareta Sannnin to Futari ("The Confined Trio and Duo") is the shortest story and starts with Adam, Hamilton and Will arguing over the death of Samson: the four of them have just committed a robbery and hid in a little cabin in the mountains, figuring the oncoming storm will certainly prevent the police from finding their trail. They found two Japanese persons in the cabin, who were promptly tied to their chairs. When the four armed robbers notice there's no connection on their phones, Adam, Hamilton and Will go out to see whether there's reception somewhere, leaving Samson alone. When they return however, they find Samson lying dead beneath the cliff outside the cabin. None of the robbers believe Samson just fell of the cliff, but the Japanese hostages are still tied tight to their chairs, so the shotgun-wielding robbers start to suspect each other of killing Samson to get a better cut. There's not much hinting to signify the 'punchline' of this story, but it's really funny and once you read the story again, you notice how wonderfully careful this story was written and how ingeniously the misdirection was set-up.

Nantonaku Katta Hon no Ketsumatsu ("The Ending of the Book Bought on a Whim") has the narrator recount the plot of the latest Inspector Saejima novel she recently bought to her boss, a bored bartender who likes puzzles and quizzes. The story is about a murder committed on an ordinary man who was out fishing on a Sunday. Rocks were thrown from the cliff overlooking his fishing spot, and it appears the man was targeted especially. Inspector Saejima starts poking around and ultimately arrives at the family of a faint acquaintance of the victim. Saejima figures the motive out, but can't seem to figure out which of the three family members did it, as they all have an alibi. The solution to this problem might perhaps miss the impact of other stories in this collection. The 'problem' is that the impossibility of this story isn't dwelled upon long enough, which kinda weakens the 'shock' the story could have, but I do think it's one of the best set-up stories, with an act of misdirection that is sooooo easy to miss and yet so ordinary. It's one of the most realistic narrative tricks, one hat any of us might have encountered in real life too by accident too and also a great example of how (socio-)linguistics can be featured in mystery fiction (socio-linguistics being a personal field of interest).

Binboushou no Kaijiken ("A Curious Incident With Poor People") is set in the Yuumeisou, a university dormitory reminiscent of Kyoto University's infamous Yoshida dormitory: it's an old, decrepit building (almost a ruin), but that's also reflected in the ridiculous low rent. Yuumeisou is mostly inhabitated by poor Japanese students, and poor international students from China, Thailand and more Asian countries. One night, the Chinese student Li cries out that something has been stolen from his room: a culinary delicacy which his mom sent over from China has been stolen from his bedroom. All the students in the dorm are gathered and eventually, they find out during what period in the night it must have been stolen, but it seems that none of the suspects could've stolen it, whether because they have a solid alibi or because they have proven to have not broken into Li's room. The story kinda plays with cultural stereotypes in terms of characterization, but it ultimately does tie in with the mystery plot in a meaningful manner and to be honest, I thought that piece of misdirection was a bit mean towards the reader, but I have to admit I fell for it completely.  There's also a deduction scene about who entered Li's room based on a set of sake bottles which was surprisingly clever: these stories aren't just about fooling the reader.

Side note: I've visited the Yoshida dormitory once while I was studying at Kyoto University. It was nuts inside.

In Nippon wo Seou Kokeshi ("The Kokeshi That Carries The Weight of Japan"), the narrator and her boss (the owner of a detective agency) are hired by a retired big-name politician of the ruling party. He wants them to track down the Headhunter, a progressive-liberal activist who has been active in Japan lately. The Headhunter's M.O. is to pull of some prank with statues all over Japan: in one case, a Darth Vader mask was put over a statue's face, while in another case, the head of a statue made from plastic was cut off and replaced with something different. While their client won't explain his reasons in detail, he ensures the detectives that "the fate of Japan" depends on them tracing down the Headhunter, and acting on a tip, everyone of the detective agency is sent to Sendai, as they have reasons to believe the gigantic kokeshi figure in Saikawa-chou will be targeted. The almost seven-meter tall doll at the station attracts tourism, so it's important they will protect it from the Headhunter's pranks. While the trains are still running, there's little fear of the Headhunter due to passenger traffic and the stores in the gallery, but things are different after the last train. The only way to reach the kokeshi is through the station gallery passage, so the detectives split up in two teams and monitor both the east and west exit of the passage. They carefully keep their eyes on everyone who passes through the gallery at night, as they can only perform a citizen's arrest if they catch the prankster red-handed. But the stake-out fails and they discover that the Headhunter succeeded in drawing two extra faces on the sides of the kokeshi doll. But strangely enough, they did not see one suspicious person enter or leave the passage: as the kokeshi's face is about six meters above ground, the Headhunter must have used some equipment, be it a ladder or rope, to climb up there, but nobody caught on camera had that much luggage with them, nor was anyone long enough in the passage to be able to draw two extra faces on the kokeshi. The explanation behind how the prank was pullled off is a bit silly if you visualize it, but it's a good ending to the book, as it incorporates elements from earlier stories.

Be sure to read what follows next to: I usually skip or just skim through afterwords, but points raised in the Challenge to the Reader at the beginning of the book are explained in detail here. The Challenge to the Reader also contained vague hints for the stories that followed, and the explanation of those hints (what they actually meant) can also be found here, so be sure to read on after Nippon wo Seou Kokeshi.

I enjoyed Jojutsu Trick Tanpenshuu a lot more than I had even anticipated though! It's really dangerous to declare out loud that you'll be trying to deceive the reader with the narration: by alerting the reader beforehand, the reader might be more inclined to see through the trickery employed and some people might find misdirection aimed explicitly at the reader to be unfair. I find that Nitadori Kei did a great job with Jojutsu Trick Tanpenshuu in terms of these points: the misdirection aimed at the reader employed is clever and often original, but always fair in the sense that he never blatantly lies and the attentive reader can actually avoid falling for his traps as long as they don't assume facts or circumstances just because they want to. And the way the misdirection aimed at the reader also ties in with the core mystery plot is also done well: the mysteries don't depend solely on the deceiving of the reader, but the misdirection is only one step in the process, and anyone who doesn't fall for the misdirection can just skip that step in the thinking process. The individual stories are actually quite interesting on their own too, even without the narrative trickery gimmick. Definitely one of my favorite reads of the year!
