This Japanese murder mystery was originally published in 1987 and is now available from Pushkin Vertigo in an English translation by Ho-Ling Wong. Having recently read two other reissued Japanese classic mysteries, The Honjin Murders by Seishi Yokomizo and Murder in the Crooked House by Soji Shimada, I jumped at the chance to read this one, especially when I saw comparisons with one of my favourite Agatha Christie novels, And Then There Were None.

After a brief prologue, the book begins with seven students, all members of their university Mystery Club, arriving on the lonely island of Tsunojima, where they are planning to spend the week. It’s the perfect location for a group of crime lovers because a series of unsolved murders took place there the year before, so the students are looking forward to exploring the island and using their skills as amateur detectives to investigate the mystery. Soon after their arrival, however, they discover that someone is planning to murder them one by one – but is the killer one of the seven or is someone else hiding on the island?

This is an interesting novel and a quick one to read; although it takes a while to get started, the pace rapidly picks up once the first murder takes place. The action switches between the island and the mainland, where Kawaminami, an ex-member of the Mystery Club, is carrying out some investigations of his own, having received a letter which leads him to question what really happened on Tsunojima Island the year before. The alternating narratives add some tension to the story as we wait to see whether Kawaminami will solve the mystery before everyone on the island is dead.

The similarities with And Then There Were None were obvious as soon as I started to read, but sadly this book doesn’t come close to the brilliance of the Christie novel – and the eventual solution and motive are quite different anyway. However, it’s clear that Yukito Ayatsuji must have been an admirer of Golden Age crime novels and he pays homage to them in various ways all the way through the book. The seven members of the Mystery Club have all taken the names of classic crime writers and are known as Ellery, Agatha, Leroux, Carr, Van Dine, Poe and Orczy, while Kawaminami’s nickname is Conan – or sometimes Doyle!

The characters themselves, though, never really come to life at all and feel interchangeable, with very little to differentiate one from another. This leads to a lack of emotional involvement and I found that I didn’t really care who was murdered or who the culprit was. I felt completely detached from what was happening and although I could appreciate the cleverness of the plot, it wasn’t a story that I could become fully absorbed in. To be fair, this seems to be typical of Japanese mystery novels in general, particularly the subgenre known as honkaku, of which this book is said to be a classic example. Honkaku books have been described as traditional plot-driven ‘puzzle mysteries’ with complex solutions and appear to be less concerned with character development.

Still, I found things to enjoy in this novel. The revelations at the end took me completely by surprise and, if I hadn’t had so many other books waiting to be read, I would have been tempted to go back and re-read at least the first few chapters to see how I could have missed the clues. And I loved the descriptions of the Decagon House, the building in which the students stay during their time on the island – a decagonal building with decagonal rooms, decagonal tables and even decagonal cups!
