Last year, I came across the work of fan-lator Mitsuda Konno, formerly known as Mitsuda Madoy, who's translating first-rate Japanese detective fiction with "cosmmiicnana" such as Kie Houjou's superb "The Ryuuzen Clan" series and Danro Kamosaki's insane "Murder in the Golden Age of Locked Rooms" series – which have become personal favorites. I keep my fingers crossed Houjou's Jikuu ryokousha no sunadokei (The Time Traveler's Hourglass, 2019), Katou no raihousha (Visitors to the Isolated Island, 2020) and Meitantei ni kanbi naru shi wo (Delicious Death for Detectives, 2022) get official releases one day. I consider them to be the classics of tomorrow and a glimpse of what the detective story could involve into over the course of this century. That's a story for another day.
Mitsuda Konno has a few more pieces of
Mikito Chinen's Garasu no tou no satsujin (The Glass Tower Murders, 2021) is described by Konno as "a mystery fan's mystery novel" that's "extremely tropey, and extremely self-aware about how tropey it is," which incidentally also makes it "good as an introduction to modern J-mystery" – dedicating "a lot of page time to explaining the appeal of its own genre." Ho-Ling Wong praised The Glass Tower Murders in his 2022 review for the meaningful way it used the genre's familiar tropes and concepts to create "a very entertaining puzzles that presented a surprising deep look at the genre" ("...basically a love letter to the shin honkaku subgenre"). Chinen's The Glass Tower Murders sounded like a trickier, more complicated and deeper shin honkaku version of Leo Bruce's Case for Three Detectives (1936). Well, I'm game!
The glass tower of the title is the setting of the story and home to Kozushima Tarou, a retired professor of biotechnology, who invented TRIDENT that "completely altered the course of gene therapy." This invention also made him a very rich man and allowed him to built the tower. A towering, cone-shaped building erected on the slope of Mt. Chogatake with glass walls and a spiral staircase at the center linking together the floor and rooms. The point of this cone-shaped building is called the Display Room where the "Kozushima Collection" is kept. Kozushima is not only a biotech genius, but "a devotee of mystery fiction" and has accumulated a huge collection of detective memorabilia from across the world ("is this Columbo's coat?"). Fittingly, the normally reclusive Kozushima has invited a small group of people to the Glass Tower to make an important announcement.
First of all, there's Kozushima's doctor, Ichijou Yuma, who pulls double duty as a Dr. Watson narrating the story. Sakaizumi Taiki, a chef, who's always called upon to cook lavish meals for Kozushima's events. Aoi Tsukiyo, a self-proclaimed Great Detective, styles herself after Sherlock Holmes, but another guest, Kagami Tsuyoshi of the Nagano Prefectural Police, says she always turns down cases that look too difficult to solve. Kuruma Koushin is a celebrated mystery novelist who made his name during the early days of the shin honkaku movement and "particularly known for his skill at creating locked room mysteries." Yumeyomi Suishou, a TV psychic, is the star of the Psychic Detective Case Files. Sakyo Kousuke is the editor-in-chief of Super Mystery Monthly Magazine known for its "scattershot approach" by "placing proper honkaku stories of logic and reasoning next to unbelievable tales of the paranormal." Lastly, the loyal butler and maid.
So there you have a fairly basic and typical setup for a conventional shin honkaku mystery novel. Conventional to the point you almost get déjà vu, however, that's the point as the story slowly, and playfully, begins to take a different track with these classic, time-honored tropes. Yuma not only narrates the story, playing the witless Watson to Tsukiyo's Sherlock Holmes, but this Watson is also a murderer who has an urgent reason to slip his employer a poisoned pill loaded with tetrodotoxin – which is the poison in pufferfish. Yuma figured if he declared Kozushima's death the result of a heart attack, "it won't be considered a crime," but his plan is completely derailed when Kozushima cries out for help over the telephone. That gives Yuma precious little time to get out of the room and create a very basic locked room setup, which he hopes will do the trick. When the door is opened with the master key, Yuma discovers Kozushima left a clue before dying. The letter "Y" written on the floor ("it must be a dying message"). Tsukiyo, of course, rejects any notion Kozushima died from natural causes or committed suicide. She gets to play detective as an avalanche blocked the road and the police won't be able to get to them for another day or two.
Roughly, the first quarter of The Glass Tower Murders plays out like a darkly humorous inverted mystery in which the murderer finds himself assisting the self-appointed Great Detective investigating his own crime. Something that could have come straight from an Anthony Berkeley or Leo Bruce novel! Yuma is not the only murderer roaming the Glass Tower. A second locked room murder soon follows the second one as Oita Shinzo, the butler, is brutally stabbed to death in the dining room with the door securely latched from the inside. The door being latched from the inside is not even the strangest aspect of the case. Somehow, the dining table was on fire with a message, "SPIRITED AWAY FROM CHOGATAKE," written on the tablecloth ("...a reference to a series of murders that happened in this region over a decade ago").
So now Yuma has a potential scapegoat and more than ever determined to help Tsukiyo find the murderer by being her Watson. However, the murderer is not done yet with creating locked room murders and other impossible situations. The Glass Tower Murders is not about its locked room murders and tricks. It's a detective novel about detective fiction with a cast of genre-savvy mystery readers who discuss various authors, novels, styles and history of the genre – particularly the development of the shin honkaku mystery. Not to mention the plot-thread about an mysterious, unpublished manuscript Kozushima's claims to have discovered that "completely overturn the history of the genre." And, of course, occasionally winking at the fourth wall ("maybe we are characters in a honkaku mystery set in a creepy mansion and just don't realize it"). Don't mistake The Glass Tower Murders for lightweight fluff or an excuse for Mikito Chinen to fanboy all over his favorite mystery writers, novels and series. The Glass Tower Murders is an incredibly dense, layered detective novel pulling off something truly amazing.
The Glass Tower Murders basically gives you three different, deeply intertwined mystery novels for the price of one. Firstly, there's the Berkeley-style inverted mystery involving Yuma poisoning Kozushima. Secondly, the conventional, classically-styled shin honkaku mystery ticking every box needed for such a novel. And that includes two challenges to the reader! This conventional portion of the novel concludes with Tsukiyo's equally conventional solution to exactly such a mystery, but the story is not over yet. So the last part offers an alternative take turning everything that happened before upside down. And brilliantly so! I can't say much more without risking serious spoilers, except how it reminded me just how popular and influential Ellery Queen is in certain non-English speaking parts of the world. Something that's not always appreciated or even noticed in the West.
Mikito Chinen's The Glass Tower Murders stands as a truly exceptional, self-aware meta-mystery novel that demonstrated you can have your cake and eat it too. You have, on the one hand, a typical shin honkaku mystery with a eccentric mansion, locked room murders, a dying message, cracking codes and a closed circle of suspects – completely shut off from the outside world. The solutions to the various mysteries of this conventional shin honkaku novel aren't half bad. Like the locked room-tricks behind the second and third murders, which give you everything you hope to get from a series of impossible crimes in a bizarre mansion. At the same time, the story goes much deeper than merely references to Hercule Poirot or the “Bizarre House Mysteries” series by Yukito Ayatsuji. Only to escape its own confines to prepare the firework show that would end the story. Simply fantastic!
I'm just not sure I would recommend The Glass Tower Murders as an introduction to the shin honkaku mystery, or the genre in general, because the plot demands some level of familiarity with the detective story. Not just for knowing who's who, or who wrote what and when, but in following the plot along as it twists and turns towards its inevitable conclusion. Today, it's easier than ever to read up on the Japanese shin honkaku mystery novel. Enough to fully appreciate The Glass Tower Murders.
So, in closing, all that's left to say is Chinen really took the meta-mystery to another level of consciousness with The Glass Tower Murders. Highly recommended.
