Paperback | 256 pages
A twisty and ingenious classic Japanese murder mystery from the author of The Decagon House Murders
Every year, a small group of acquaintances pay a visit to the remote, castle-like Mill House, home to the reclusive Fujinuma Kiichi, son of a famous artist, who has lived his life behind a rubber mask ever since a disfiguring car accident. This year, however, the visit is disrupted by gruesome murder, a baffling disappearance and the theft of a priceless painting.
The brilliant Kiyoshi Shimada arrives on the scene, but as he investigates the seemingly impossible events of that evening, death strikes again, and again...
 Can Shimada get to the truth before the killer gets to him? And can you solve the mystery of the Mill House Murders before he does?
