The original 1987 mystery novel by Ayatsuji is often credited by mystery fans in Japan as launching the shinhonkaku (New Orthodox) mystery sub-genre. The sub-genre includes many elements of classical mystery fictions, such as elaborate locked rooms and game-like puzzles that audiences are also expected to piece together, but also including elements of postmodernism and metatextual references, veering away from realism and embracing fantastical playfulness, nihilism, and absurdity.

Locked Room International published an English translation of the novel (translated by Pushkin Press published a new version of the book (with the same translation) in May 2021. Pushkin Press describes the novel:

Taking its cues from Agatha Christie's locked-room classic And Then There Were None, the setup is this: The of a university detective-fiction club, each nicknamed for a favorite crime writer (Poe, Carr, Orczy, Van Queen, Leroux and — yes — Christie), spend a week on remote Tsunojima Island, attracted to the place, and its eerie 10-sided house, because of a spate of murders that transpired the year before. That collective curiosity will, of course, be their undoing.

As the students approach Tsunojima in a hired fishing boat, 'the sunlight shining down turned the rippling waves to silver. The island lay ahead of them, wrapped in a misty veil of dust,' its sheer, dark cliffs rising straight out of the sea, accessible by one small inlet. There is no electricity on the island, and no telephones, either.

A fresh round of violent deaths begins, and Ayatsuji's skillful, furious pacing propels the narrative. As the students are picked off one by one, he weaves in the story of the mainland investigation of the earlier murders. This is a homage to Golden Age detective fiction, but it's also unabashed entertainment."

final volume shipped in May 2022.

Ayatsuji published the Another horror mystery novel in Japan in 2009. The novel inspired a 2012 anime by published both the original novel and the manga adaptation in English.
