This is a shinhonkaku murder mystery (another description) where the mystery is supposed to be "fair" and the reader is challenged to solve it before the solution is revealed.

There is a manga adaptation of that book. Huh.

Anyway, another Japanese mystery on sale for $1.99: Death on Gokumon Island by Seishi Yokomizo.

A fiendish, classic locked room murder mystery, from one of Japan's greatest crime writers

Loosely inspired by Agatha Christie's And Then There Were None, the brilliant Gokumon Island is perhaps the most highly regarded of all the great Seishi Yokomizo's classic Japanese mysteries.

Detective Kosuke Kindaichi arrives on the remote Gokumon Island bearing tragic news--the son of one of the island's most important families has died, on a troop transport ship bringing him back home after the Second World War. But Kindaichi has not come merely as a messenger--with his last words, the dying man warned that his three step-sisters' lives would now be in danger. The scruffy detective is determined to get to the bottom of this mysterious prophecy, and to protect the three women if he can.

As Kindaichi attempts to unravel the island's secrets, a series of gruesome murders begins. He investigates, but soon finds himself in mortal danger from both the unknown killer and the clannish locals, who resent this outsider meddling in their affairs.

I picked up books 1 (The Honjin Murders) and 6 (The Inugami Curse) of this series when they were on sale.
