Disclosure: I translated Ayatsuji Yukito's The Decagon House Murders, The Mill House Murders, The Labyrinth House Murders and of course, The Clock House Murders.
In 2024, Hulu released a wonderfully produced live-action adaptation of The Decagon House Murders. It just so happened I actually was going to meet author Ayatsuji Yukito the day after it was released, so I binged the series the night before, so I could actually talk about it to him. Like many others, I too was curious how they were going to actually film the book, as it is a very difficult work to adapt for certain media, but the result was honestly really, really good. So when I learnt last year they were going to do an adaptation of The Clock House Murders in 2026, I was thrilled: given how good The Decagon House Murders was, I have only high expectations for this new release, which was released this very week. Obviously, The Clock House Murders is a book dear to me: not only because it's easily one of my favorite books in the series, I also did the English translation of the novel, so I spent a lot of time on, and with the book.The live-action series releases today (Friday 27th), so I haven't seen the series yet at the time of writing this post. While they released the complete The Decagon House Murders series on the release day two years ago, this time they are splitting the release across two batches, with the first six episodes presenting the main problem released this week, and the last two episodes, with the solution, releasing next month. So I might binge everything next month in one go.
To celebrate the release of this adaptation, the literary magazine Shousetsu Gendai (published by Kodansha, the Japanese publisher behind Ayatsuji's House books) featured a The Clock House Murders special in its March 2026 issue, with not only interviews with Ayatsuji, Arisugawa Alice and one of the main actors of the series, the magazine also featured no less than five (!) original "House"-inspired mystery short stories, written by as many authors.
The first story featured is Aosaki Yuugo's Kubisogiyama no Kaiten Yashiki ("The Revolving Manor on Mt. Kubisogi"). The titular Revolving Manor is one of the six manors built by the legendary architect Kurotsubo Shinku. This particular building stands on Mt Kubisogi in the Hyogo Prefecture, and is best imagined as one of those revolving restaurants that offer a 360-degree panoramic view. The "entrance" of the house is actually just an elevator shaft: the elevator that leads up to the circular house built on top of that shaft tower. The house consist of three "rings". The fixed outer ring is the outer wall of the building, and is made of acrylic: the whole outer wall functions as a window, offering a panoramic view. The middle ring is built right against this outer window/window and holds most of the rooms, liking a sitting room, study and bedroom. This ring slowly revolves clock-wise, meaning each room not only has an amazing view, this view actually changes depending on the time! The inner "ring" is the static center of the house around which the second ring revolves, holding the elevator entrance, bathroom and kitchen.
The house is currently owned by Nishikubo Hiroyuki, who runs a make-up company. He and his wife are visited by a crew from a magazine on architecture for an article on the house. The crew are to stay for the night at this unique creation by the enigmatic architect Kurotsubo. The members all stay in a different room. The following morning however, a gigantic hole is found to have been carved out of the acrylic window. It's clear it wasn't just broken by accident, but someone actually bothered to open a hole in the outer wall. Down on the ground, at the base of the elevator shaft, they find one of the crew members lying dead, seemingly having fallen through the hole down the tower. Everyone is perplexed by the situation: did someone kill him and then cut a hole in the window to dump the body downstairs? But what purpose could that have?
This story is actually a sequel to an earlier Aosaki story, which features another house (The Glass Manor) by the architect Kurotsubo. I have the book, but I haven't read it yet. But it's no problem if you start here. The house in this story is actually pretty "normal" all things considered: I can easily imagine someone wanting a revolving house in the mountains with the complete outer wall acting as a window so you can always enjoy the view! It's not a particularly long story, which is why I was surprised Aosaki manages to pack quite a lot into the story, from a secondary storyline involving the narrator to a few (very short) wrong theories and then we have the actual explanation of what happened and it's... pretty hilarious if you visualize what happened and how the victim found their death. It's not mind-blowing good, but I do like the story for its subdued silliness and I'd love to see a live-action adaptation of this! I think Aosaki could even have gotten away with just that one main idea, so I do appreciate it how he decided to still add some more story details that weren't that necessary.
Ibuki Amon's Tsubaki Fujin no Subarashii Yakata ("Madam Tsubaki's Wonderful Home") is a historical mystery, as we may expect from Ibuki. Set in Manchukuo, we follow private detective Tsukisamu Sanshirou (also appearing in this collection), who is hired to find the brother of a young woman. When their father died, the whole family fortune was stolen by their uncle. The young woman and her mother managed to find some work to earn a humble living, but her brother ran away. He became a robber and eventually made it to the position of captain within his gang of robbers: his robbers already took revenge on their uncle. His sister had not seen her brother in a decade, but recently got a letter saying he had been wounded and was now recovering in a strict medical institution run by a Mrs. Tsubaki: patients aren't allowed to write or receive any letters, but he managed to get one of the suppliers to deliver a letter to his sister for him. He would write again later on, but she never got more news from him and when she asked the deliveryman to go ask at the institution, he was found out by guards and beaten to death. Tsukisamu happens to know Mrs Tsubaki from his time working for the railway ministry. He decides to pay the institution a visit, and is shown a truly wonderful place where wounded Manchurians, from criminals, to simple women and children, are slowly nursed back to health with all the love and care they need... but Tsukisamu knows there's something wrong about the house and the intentions of Mrs. Tsubaki.
I'd be lying if I didn't say I was a bit disappointed when I realized the "house" in this story was not as important as in the other stories in this feature: the focus of the mystery lies more on the intentions of Mrs. Tsubaki and why she is running this hospital. As one can expect from Ibuki, it's a great historical mystery though, set very firmly in the time period and setting of the story, which is of course also fairly original as you don't have many present-day mystery writers anymore who use Manchukuo as a setting. The motive for Mrs. Tsubaki's actions is set-up wonderfully and eventually, Tsukisamu arrives at a heinous plot hiding within Tsubaki's seemingly wonderful hospital. Less of a "add-clue 1-and-clue 2-to-arrive-at-answer 3" mystery, more of a "given-these-remarks, can-you-imagine-why-someone-would-do-this?" type of mystery, but still well-done.
Kesshoukan no Satsujin ("The Crystal House Murders") by Ooyama Seiichirou is set in November of 1990 and first introduces the reader to a group of friends, consisting of Ryouta, Kouji, Shuuichi, Rikka, Maki and Satomi. They are staying at the Crystal House, a small hexagon-shaped hotel in Hokkaido. They have been friends since primary school, and still meet once in a while even now they're all adults. The Crystal House is owned by Ryouta and not in business just yet, but he's giving his friends a sneak peek at his new business adventure. The friends have a pleasant night in the Crystal House, surrounded by nothing but nature and snow, but the following morning, Rikka is found murdered in her room: her head's been bashed in and for some reason, her left hand has been cut off. Rikka has always been the mysterious one of the group, with strange powers of clairvoyance, but is that why she got killed? When they try to call the police, they find the line's dead. Is the murderer someone from outside, or is it one of the friends, and why was the victim's hand cut off?
This is probably my favorite story in the feature, partially because the story feels the most like a story inspired directly by Ayatsuji's House series, with a few cool nods like the cut-off hand, as well as a great set-up of the narrative: the tale actually starts with a news report detailing how the Crystal House went up in flames and how everyone but one person staying at the hotel had died: one person made it out alive and was saved by the emergency services, but is seemingly suffering from amnesia, with no recollection of the events that led to the deaths of all the people in the hotel. This "book-ending" mystery of who the survivor actually is, and what their role was in the deadly events that occured inside the Crystal House starting with Rikka's death, add a great extra layer to the mystery. The mystery of the cut-off hand, as said, invokes a few moments from Ayatsuji's house series, but the way Ooyama develops this clue feels much more Queenian than Ayatsuji would generally do. So even though the "prop" is the same, Ooyama definitely makes best use of his own expertise, using the cut-off hand for a proper physical-clue-based chain of deduction. I really like what he does with the Crystal House here as a setting too, giving it a unique vibe, and the whole tale feels really complete.
Shasendou Yuuki's Goumonkan no Satsujin ("The Torture House Murders") has the WeTuber Kugi Hikage and her assistant visiting the Torture House, as Kugi is best known for visiting houses with a nasty background stories. Twenty years ago, Horikoshi Toutarou, the original owner of the house kidnapped a few people to torture them to death in his basement with his collection of torture device. One victim managed to escape eventually and notified the police, leading to Horikoshi's arrest. The house, now known as the Torture House, was later bought by Nukube Ikurou and he had an exact copy of the Torture House built next to the original. He has preserved the original Torture House and has a caretaker there keep an eye on things, while he lives in the copy. As this copy houses his collection of antique wares, he has dubbed it the Antique House. He has invited a few people interested in the Torture House and the torture devices kept in the basement to view them, with Kugi as one of his guests. The tour is to be held the next day, but when Nukube doesn't appear in front of the Antique House the next morning as agreed upon, the group crosses a snow-covered field to head for the Torture House themselves. The caretaker there states he did see his master come to the Torture House yesterday. He had assumed Nukube had returned to the Antique House for the night, but the complete absence of footprints in the snow suggest Nukube never left the Torture House. When the group enter the dark basement, they find a dead Nukube, who has been clearly tortured to death, with his joints and bones broken. Unfortunately for the caretaker, it seems that he's the main suspect as he was the only other person in the Torture House last night.
Setting-wise, I really love this story, as the backstory of the Torture House is really cool, as well as the idea of an Antique House full of weird curiosities. It's why I am a bit disappointed that due to the way this story was structured, one person stands out a bit too much as the only viable suspect, which immediately limits the ways the murder could've been committed. The story does make cool use of the torture theme though. I also like the idea of how Kugi manages to trap the murderer in principle, but the way it is written now, the clue depends very much on trivia, while I think it could probably have been written in a way to be a bit fairer towards the reader, if they happen to not have certain knowledge.
The last story, Kokushikan Satsujin Jiken ("The Black Arrow Mansion Murder Case") by Takemoto Kenji, is one I'm not going to discuss in detail. The story is about the detective Norimuzu Rintarou who's asked to look into the disappearance of the owner of the Black Arrow Mansion in Saga Prefecture. Some readers will probably already have realized it by now, but this is a full-on parody of Oguri Mushitarou's Kokushikan Satsujin Jiken, one of the most notorious anti-mystery novels from Japan. Takemoto goes full throttle here, doing not only direct mirrors to scenes from that book, but the story is also absolutely brimming with countless of literary references that may or may not be real and characters who don't speak like humans but like... well, I guess, like AI that tries to sound smart and well-read. The story is basically only fun if you know the original Kokushikan Satsujin Jiken and recognize what this story is mirroring exactly. For Takemoto does that really good, it feels as frustrating to read as the original! (Considering the author's intent, this is praise).
Overall, I think this The Clock House Murders feature in Shousetsu Gendai was pretty fun though, and it's great seeing all these authors doing a take on a house-based mystery. I'm looking forward to watching the live-action adaptation too. If you haven't already though, please consider reading the English translation of The Clock House Murders too, as it's really a great mystery novel!
