Murder in F Sharp

"How do you go about writing a detective story?"

- ""Well, you forget detection and concentrate on crime. Crime's the thing. And then you imagine you're going to steal something or murder somebody."

"Dial M for Murder"

When it comes down to it, I do really like reading series though, not because of recurring characters per se, but because it gives me a framework (settings/themes) of what I can reasonably expect. Which is why I often stick with series and seldom seem to try "new" things.

The Box of Genesis is a coffin-like box created in medieval times, of which it is believed it can make objects appear out of nowhere. While most believe it is an urban legend, its powers were proven to be true in 1982, when a German scientist who managed to obtain the Box of Genesis held a reception to show the Box off. Early in the party, a reporter asked to take a look inside, and everyone saw the Box was empty. The Box was left in the middle of the room, with the party going on around it, until near the end of the reception the reporter asked to have have another look inside. To the shock of everyone present however, they found a cut-up corpse inside the Box of Genesis, even though the Box had been right in the middle of the reception all that time and nobody could've just walked up to the box to put a bloody body inside without anyone noticing. While for some time, the police suspected its new owner of foul play, they never managed to figure out how where the body had come from, cementing the legend of the Box of Genesis. 

Eventually, the Box of Genesis found a new owner in Japan. The art collector Iwakura is also the owner of the Alphabet House, a mansion in the mountains that used to house missionaries. Long ago, these missionaries placed sculptures of some letters of the alphabet in the courtyard, and subsequent owners all added similar sculptures, and by now, all 26 letters of the alphabet are found in the mansion's main building, its annex and the courtyard that connects the two buildings. Iwakura often has house parties, and it's in 1998 that he invites a rather curious bunch, from a private detective to a doctor to Mikutsuki Miyuki, an actress in the theatre troupe Polka, who is accompanied by felllow actress/roommate Miiko and "De", a friend with a mysterious past. "De" has lost all memories of his past, but is a brilliant detective specializing in impossible crimes, hence his name "De" (from "Detective"). Once they arrive at the Alphabet House, the guests learn that their host isn't present yet, though the two part-time servants he has hired have all the instructions they need to entertain his guests. But Miiko hears from one of the guests that their host Iwakura might actually have been murdered some months ago already, leading to the question who actually invited them here. The guests also find the Box of Genesis in the large hall in the annex, and one of the people present happens to know about this out-of-place artifact (OOPart), telling them about the legend and the 1982 murder. The following morning, one of the guests staying in the annex can't be found anywhere there, despite the lack of footsteps in the snow in the courtyard, meaning they must still be in the annex. The Box of Genesis is missing. When the guests move to the main building, they find the Box of Genesis in the large hall on the second floor of the main building... with the murdered missing guest inside! But how did the victim, and the Box of Genesis go to the main building without leaving any footprints in the snow in the courtyard? The people are still wondering about what has really happened when another murder happens and a decapitated head appears inside a locked Box of Genesis. Can De figure these murders out in Kitayama Takekuni's Alphabet-sou Jiken (2002), which also has the English title The Case of Alphabet? 

I have read more than a few mysteries by Kitayama, but in a way, my reading of him is also very limited, as everything I have read of him fall into just two series: either it's his own four-novel Castle series, or it's the work he has provided for the Danganronpa franchise, like the Danganronpa: Kirigiri novels. Kitayama's best known for his technically-constructed locked room mysteries, with ingenious (and slightly over-the-top, ridiculous) mechanisms that create these impossible situations, and this aspect of his work is very clearly visible in the above-mentioned two series. Alphabet-sou Jiken was originally published in 2002, being a revised version of a novel he had written before his professional debut. The book had been published in a label of publisher Hakusensha, which was surprising to me, as it was not a publisher I immediately associate with mystery novels, even though they have mystery manga (like the classic Puzzle Game ☆ High Schooi). The book had been out of print for a long time, but saw a re-release by a different publisher in 2021 with a brand-new cover, and I figured it'd be an interesting way to read something beyond the two series I already knew.

Which is why it surprised me that thematically, Alphabet-sou Jiken is basically a side-story to the Castle series. There's a brief mention of a legend of the "Six Daggers of the Headless Knights" in this book, which is a recurring motif in the four books in the Castle series: while the settings/characters of those books are all completely unrelated, they do all refer to legends concerning cursed daggers and headless knights. But besides the cheeky reference, I'd say Alphabet-sou Jiken also feels very close to the Castle books in terms of atmosphere, with somewhat stange, almost cartooney characters and a distinct, fantasy-like vibe that delves into themes of fate and destiny, as well as a focus on legends. Had this been touted as a "full" spin-off of the Castle series, I would have believed it, and as this book was written before Kitayama's professional debut, I can't help wonder whether this book served as a prototype in terms of characterization and world-building for the Castle books, or whether he added these elements later when he revised it for the publication. One of the more obvious parts is early in the story, when one of the characters remarks the setting they are in is basically a detective story, and the character proceeds to destroy/damage the landline phone and the mobiles of the people present to intentoinally create a closed circle situation, to intentionally tempt fate so a murder will happen. This is also why, together with the harsh weather conditions the following day, the people inside the Alphabet House are not able to send for help immediately after the discovery of the murder. This is the type of meta-action we've seen in the Castle series before (especially 'Alice Mirror Jou' Satsujin Jiken), which have a distinct, fantasy-mystery-like atmosphere, but the first time you come across it in Alphabet-sou Jiken, it is rather surprising. Some may not like these kind of characters/actions, but it's another reason why I thought this book was basically a stealth entry in the Castle series.

As for the mysteries in this book, I felt the book does feel less refined than other works by Kitayama, probably because it was based on an older story. Most importantly, the two plot elements of the Box of Genesis and the alphabet structures in the Alphabet House feel completely unrelated, and you keep wondering why the book is about these two things: a box which can conjure objects out of nowhere, and a house with letters of the alphabet spread across the two wings and the courtyard. These are two completely different themes, so it just feels weird this book is about these two curious themes. I would've liked it if there was some kind of stronger backstory linking the two parts, rather than just "the current owner of the Box of Genesis also happens to be living in the Alphabet House." This book is fairly short, but I think it would have benefitted from more pages, allowing to build a stronger link between these elements and flesh out some of the events more.

As for the mysteries, I think the solutions are a bit simply, and perhaps undeveloped at times. For example, eventually, De also decides to tackle the 1982 case and he proves the cut-up body appearing in the Box of Genesis during a reception wasn't magic, but foul play, but the trick used there is in concept perfectly fine, even if simple, but doesn't quite practical, as it'd be easy for anything to go wrong with that method, (especially timing!), resulting in a botched plan rather easily. I do like how the fundamental concept of this trick is used in a very different, but related way in one of the 1998 murders, even if the method used there also seemed rather risky and prone to early discovery. The biggest mystery in this novel is of course the first 1998 murder, where the Box of Genesis and the first victim manage to disappear from the annex and reappear in the main building in one night, without anyone leaving any footprints in the snow in the courtyard. This part of the mystery is probably fairly easy to solve if you've already read a few Kitayama novels: it's the kind of trick he likes to use, and especially once a certain prop is introduced in the story, it's rather easy to guess how the murderer managed to pull the thing off. I think the misdirection that's pullled off here is interesting though: while I do honestly think it's easy to guess what happened even now, I think it is hidden in a way that can works best in its current form, in prose, in the letters on the page. If you'd visualize everything, I think the trick would have been even more obvious, so I did like that, because I only realized how really easy it'd be to guess the trick if you actually saw everuthing. That happens quite often with Kitayama's work I suppose, because of his love for more mechanical tricks, utilizing space and making use of moving object in general.

The ending has a nice bitter-sweet taste to it, like we often have in the Castle series (another similarity!). I like how the ending, almost surprisingly, does address some of the lingering questions I still had, specifically why these people had been invited to this party, and the themes of romance, fate and destiny touched upon in this ending are also themes we see developed more further in the Castle books, cementing Alphabet-sou Jiken as a proto-entry in the series. If you like the tone of those books, you'll definitely like this book too.

So in the end, I did not manage to move away from my familiar corner of Kitayama Takekuni's work by reading Alphabet-sou Jiken. It fits perfectly in the model of the Castle novels I already knew, but I do think I enjoyed the book more exactly because of it. As a mystery novel, Alphabet-sou Jiken does feel a bit lacking compared to the other Kitayama novels I've read: the tricks used are a bit simple and practical problems are ignored a bit too easily. Had it been a longer novel, some of these problems could've been helped I think, though I guess that ultimately, the four Castle novels are exactly that: more developed versions of the story found within the pages of this book. I wouldn't consider this book a must-read, but definitely interesting for those who have already read a few Kitayama works, to see what they can recognize in this work.
