The Locked Village and the Eight Tricks (2024) by Danro Kamosaki

Last year, I discovered Danro Kamosaki's "Murder in the Golden Age of Locked Rooms" series, translated by Mitsuda Madoy and "cosmmiicnana," which aims to push the limits of the impossible crime story by pumping it full of performance enhancing substances – results didn't disappoint. That is, if you're addicted to locked room mysteries to the point it has family and friends worried. But if you're a locked room addict, the premise of this series is a dream come true.

A suspect on trial for Japan's first ever, real-life locked room murder was acquitted, because the prosecution could not provide a solution or theory explaining the locked room. So, "if the scene is a perfect locked room, it's the same as the culprit having a perfect alibi," became a legal precedent over night as impossible crimes started to dominate Japan's crime statistics ("...a third of all murders..."). Along with the rise of locked room murders came a whole new industry of experts ranging from detectives and criminals specialized in impossible crimes to appraisal companies checking houses for secret passages or hidden rooms.

Kasumi Kuzishiro, an 18-year-old high school student, often feels like he's involved in half of all locked room murders plaguing Japan. Usually, Kuzishiro is dragged along by his childhood friend, Yozuki Asahina, to go hunt for UMA (Unidentified Mysterious Animal) in a remote, isolated place that becomes the scene of a series of impossible murders. Misshitsu ougon jidai no satsujin – Yuko no yakata to muttsu no tricks (Murder in the Age of Locked Rooms – The House of Snow and the Six Tricks, 2022) brought them to the former house of a famous mystery novelist hosting half a dozen locked room murder, which is incidentally also the most conventional of the three. The second title in the series, Misshitsu kyouran jidai no satsujin – Zekkai no katou to nanatsu no trick (Murder in the Age of Locked Room Mania – The Solitary Island in the Distant Sea and the Seven Tricks, 2022), takes the isolated island trope, understandably popular in Japan, to the extreme and adds an extra impossibility to the tally – while maintaining a decent balance between quality and quantity. So every single one is a winner, but most show imagination, originality and some are so good they could have solo carried a locked room mystery novel. Even if they can be a little outlandish at times. Danro Kamosaki evidently wrote this series for the love of the game and the game here is a locked room extravaganza. The third title in the series is no exception.

Misshitsu henai jidaino satsujim – Tozasareto mura to yattsu no trick (Murder in the Age of Locked Room Fetishism – The Locked Village and the Eight Tricks, 2024) begins with Yozuki dragging Kasumi on another UMA hunt, but they get lost and end up in strange, remote village just in time to get embroiled in what came to be called "Yatsuwako Village Octuple Locked Room Murder Case."

Japanese detective fiction is littered with these strange, fictitious and isolated villages with their own unique history and customs. Seimaru Amagi's Ikazuchi matsuri satsujin jiken (Deadly Thunder, 1998) is always my go-to example, but Yatsuwako Village takes that concept and takes it to another extreme. Yatsuwako Village is tucked away inside a vast limestone cavern, "twenty times the size of the Tokyo Dome," shaped like a giant square with a massive fissure, dividing the village into east and west halves, connected by a bridge – where five hundred villagers lived and worked for generations. Stranger yet is its architecture and folklore. Every building in the village is a white, box shaped structure with steel doors and fixed windows. They're all plastered over until they're airtight. This is done to keep the kazeitachi, "a beast of the winds that can transform its body into air and infiltrate a house through the tiniest gap," out of their homes. Beside a wind yokai, Yatsuwako Village is also the home of a family of mystery writers dominating the locked room genre in Japan.

Zerohiko Monokaki, family patriarch, multimillionaire, all-purpose genius and occasional mystery writer, whose children would go on to dominate the Japanese mystery scene by combining the locked room puzzle with their own specialized subgenre/category of detective fiction. Ryouichirou Monokaki (social school), Kyoujirou Monokaki (hardboiled), Isaburou Monokaki (forensic/medical), Tabishirou Monokaki (travel mysteries), Fuika Monokaki (sci-fi mysteries), Funika Monokaki (YA mysteries), Fumika Monokaki (historicals), Mei Monokaki (Gothic). There's also Camembert Monokaki, the fifth son of the family, who's not a genius mystery novelist ("...just a pretty face"). Lastly, Fuichirou Monokaki, eldest son of Zerohiko and former head of the family, considered to be greatest locked room artist the country produced and passed away several months before the story's opening. So the Monokaki family dominated the ranking of publications like This Locked Room Mystery is Amazing! for years, but not wholly unopposed. Teika Ojou, the Young Empress of Japanese Mystery, took the #1 spot several times during their reign ("...state of locked room mysteries was a battle between the Monokaki Family and Teika Ojou").

Curiously, Teika Ojou is currently staying at the Monokaki mansion to dodge one of those pesky deadlines. The impossible crime lore of the village doesn't end there. The Eight Locked Room Masters of the Showa Era were "eight genius mystery novelists who appeared one after the other in the 1940s" and a collaboration between them was announced in 1953, which brought them to the village. And, of course, they were brutally murdered. A collection of their best locked room-tricks disappeared never to be found. So, in order to appease their spirits following a string of deaths and misfortunes, the murdered authors were enshrined as "a composite deity under the name Yazuwako Myojin" – dedicating a yearly festival to it. This festival is about to start when Kasumi and Yozuki wander into the village, just in time for the killing to begin. It starts out in a borderline cartoon-ish way.

During the festival, in the middle of a crowd, someone dressed as the kazeitachi, black cloak and a mask of a weasel, shoots Fuika Monokaki in the head, throws a smoke bomb and disappears alongside the body. However, this first murder is not the first impossibility of the story. That comes next! Nobody is allowed to enter or leave the village during the week long celebration and "anyone who violates this taboo will be killed by the curse of Yatsuwako Myojin" ("...the pain the curse inflicts as you die is beyond imagining"). Considering they have a shooting on their hands and murderer on the loose, they try to get out only to find the sole entrance cut-off. And then one of the villages, before bright red flames started streaming from his mouth and bursting into "an enormous pillar of fire." The man had burst into flames with nobody standing near him! From that point onward, Kasumi and Yozuki are confronted with apparently never ending series of locked room murders of various complexities.

There are more of them than the book title suggests. So the impossible crimes, like in the previous novel, are divided in more digestible lumps with the first five dominating the first-half. I already mentioned the spontaneous human combustion in the tunnel entrance, but soon they get confronted with four gruesome murders they dubbed "The Locked Villa," "The Locked Storehouse," "Locked Room of the Spiderwebs" and "Bloodstained Japanese Locked Room" – executed in both sections of the village. Kasumi and Yozuki briefly get separated when the bridge linking both parts goes down stranding Kasumi on the east side and leaving Yozuki on the west side. There some unusual detectives arise to give the first, mostly false-solutions to the locked room killings. You can argue this first badge of locked room murders can be paired, thematically speaking.

First of all, the murders in the villa (east village) and the spiderweb room (west village), which are first explained (independently) by a twin-switch trick. You see, three of the Monokaki daughters are triplets. While I normally detest "twin magic," the way they were used for the false-solutions here are perfectly fine or horrifyingly brilliant. Preferable to the correct solutions, especially the solution to spiderweb room. By the way, the spiderwebs refer to the spiderwebs blocking a secret passageway and provides a double-layered (false) solution. One with the kind of horror (concerning the body) you almost expect from Japanese mystery writers and the other feels like it belongs in a cozy mystery (involving the spiderwebs). The correct solution to the locked villa is certainly an inventive, very involved trick, but found it to be the least impressive trick of the bunch. My reaction to learning the answer was pretty much the same as Kasumi, "of course they did."

The murders in the locked storage room and Japanese room are examples of that shin honkaku specialty, the corpse-puzzle. The locked storehouse involves a mutilated body found hanging in a curious position, unlikely in hangings, but somehow the murderer had evaded being caught on the security footage. This is perhaps the easiest one to solve, but a nicely done locked room puzzle and a typical example of the corpse-puzzle and what can be done with it. However, the murder in the Japanese room is a highlight of the book! A decapitated body is found inside a so-called Japanese room with sliding doors, doors without locks, but "an extremely unique locked room" is created by the spray of blood from the decapitation. The spray of blood splattered on the sliding doors, where the doors touched, "dried to the consistency of dry oil paint." So how could the murderer have left the room after the murderer without disturbing the blood pattern on the door? The visual image the solution conjures up is pure, undiluted nightmare fuel that makes grisly scene of the murder itself seem warm and cozy. It almost feels wasted in a novel crowded with elaborate, often technical locked room murders and impossible crimes.

Yes, this is a very densely-plotted mystery that's all about tricks and locked room obsessed characters, but there was a short, too short, reflection on the impact of locked room murders becoming a major social issue on the character-driven, realism obsessed social school of crime fiction – whose writers struggled with their new reality. Basically, "the positions of locked room authors and social school authors had been completely reversed." I thought it was an interesting side effect on society and culture from locked room murders becoming an everyday reality. Back to the onslaught of locked room murders.

At this point, another friend of Kasumi turns up to assume the role of detective and solve the case, Shitsuri Mitsumura, who was to nobody's surprise in the village all along. She's one of those locked room obsessed character with a talent for seeing right through every trick. Kasumi calls her "an apostle of the locked room," because "if there was a God of Locked Rooms in this world, and that God had to pick one person from Earth to be his messenger, she would definitely be the one he'd choose." Once she destroyed the false-solutions and resolved the previously discussed murders, the process begins with a whole new array of stranger, more elaborate locked room murders. These are "The Locked Temple," "Locked Room of Four Color Boxes" and "Locked Underground Maze."

The locked temple is the least complicated, most straightforward of this badge, conventional even, but the next few get really bizarre and progressively larger in scale. Like the body they found in a room crammed with boxes of various sizes and colors blocking the door opening inwards, which looks like a game of Tetris was interrupted when a body materialized. A locked room premise that tickles the imagination and liked the explanation, but, at this point, the plot gets a crammed while the story needs to hurry on – lessening the impact of the tricks a little. Same goes for the murder in a massive, watched indoors maze giving away Danro Kamosaki is a Yukito Ayatsuji fan, but it honestly needed its own novel in combination with the bonus content. Why stop at eight? As the plot unravels further, it's revealed there's a ninth and tenth locked room mystery hiding in the Yatsuwako Village Octuple Locked Room Murder Case. The ninth locked room, a truly gargantuan locked room, shows the advantages of a customized setting designed to host a series of impossible crimes.

So, once all the locked room-tricks have been revealed, there only a few characters left standing who could have perpetrated this small scale massacre. It's not the murderer's identity that makes the solution memorable, but the motive behind the murders and locked room trickery. A unique motive that could have only emerged in this strange, locked room obsessed world.

Danro Kamosaki created a plot technical marvel in the impossible crime genre with his three "Murder in the Golden Age of Locked Rooms" novels, but, crazy as it may sounds, this series is not done yet! There's still the unresolved, ongoing storyline involving Kasumi Kuzishiro, Shitsuri Mitsumura and Japan's first unexplained locked room murder that started the locked room craze. So a fourth book is probably in the works, but no idea where Kamosaki could go from here. Maybe a locked room serial killer terrorizing an entire city or a trail of impossible crimes scattered across a hundred year period. Either way, I hope to get to read it. Let's tidy up this messy, overlong rambling review.

Like I said, The Locked Village and the Eight Tricks is overflowing with clever, often wildly original locked room-tricks and a buffet for impossible crime fanatics who want to read about ingenious locked room murders without storytelling and characterization distractions. However, the amount of tricks and ideas crammed into this novel is perhaps too much and came at the cost of the latter, much more elaborate and sometimes interconnected tricks – which needed more space to fully do them justice. That would have doubled the size of the book, but I would have taken a two volume treatment of the Yatsuwako Village Octuple Locked Room Murder Case. This simply packed too much in too short a novel making it harder to keep track of everything and detect along. Regardless, The Locked Village and the Eight Tricks is still a mind boggling achievement, technically speaking, even when compared to the previous novels. I stated in the past four impossibilities is magical number, or sweet spot, because you start running into quality control problems when trying to juggle five, six or more. You can't possibly deliver good, satisfying or even original solutions for each of them. Danro Kamosaki proved me wrong with this series. While overdoing it just a bit, I really shouldn't complain about a mystery giving me nearly half a dozen locked room murders littered with floor plans, diagrams and time tables.

Highly recommended for locked room fanatics, but to be avoided, like the plague, by everyone with a low tolerance for locked room and impossible crime fiction.

Note for the curious: here's my idea about what could be behind the first locked room murder that kicked off the locked room craze. Having now read all three, there's an increasing madness surrounding the locked room phenomena. From the rise in crime in the first novel to the religious sect in the second and finally descending into real madness in the third. An obsession manifesting in complex physical and technical locked room-tricks. So wouldn't it be ironic if that was first locked room murder was a non-impossible crime disguised and made to look like a locked room murder from fiction. A disguise protecting it from the then most well-known solution from fiction and forcing the police, prosecution and any amateur detective to chase a phantom trick. Not sure how it was done and, technically, it would count as a locked room-trick, but one subtle enough be overlooked in this universe obsessed with physical and technical, science-based tricks.

By the way, the phrase "phantom library" is used in reference to a fictitious library said to contain "every locked room mystery ever written" ("...2,628,000 locked room mysteries...").
