The Decagon House Murders is a milestone in the history of detective fiction. Published in 1987, it is credited with launching the shinhonkaku movement which restored Golden Age style plotting and fair-play clues to the Japanese mystery scene, which had been dominated by the social school of mystery for several decades. It is also said to have influenced the development of the wildly popular anime movement.
