The Decagon House Murders

Available for the first time in English, Ayatsuji's debut novel was first published in Japan in 1987, the same year as the debut of Paul Halter, another giant of locked room mysteries. Ayatsuji reinvigorates the classical English mysteries of Agatha Christie, Dorothy Sayers, Ellery Queen, and John Dickson Carr by stripping them down to their essentials and examining their moving parts. In this novel, six members of the Kyoto University Mystery Club—each taking the alias of a famous mystery writer—assemble on an abandoned island and take up residence in a decagonally shaped house. Naturally, soon enough the students begin to be killed off, and the race is on to discover the murderer's identity. Meanwhile, back on the mainland, two members of the club who chose not to go receive mysterious letters that lead them to believe that something is afoot on the island. Along with an enthusiastic partner, they set about trying to solve another mystery from years past, which has connections to the island. Ayatsuji leaves no doubts about his intentions, making copious references to Christie's And Then There Were None, and even the characters are well aware that they have stumbled into a work of their favorite type of fiction. The metafictional trappings are good fun, but they wouldn't mean much if the mystery itself wasn't equally fun and tricky. And it is.
