The Labyrinth House Murders by Yukito Ayatsuji

A group of visitors is lured to a remote, maze-like mansion built by an infamous architect, only to be ensnared in a succession of seemingly impossible murders that exploit the building’s confounding design. As fear and suspicion spiral, clues hidden in floor plans, optical tricks, and secret routes reveal old grievances and a carefully staged pattern of misdirection. A patient investigator untangles the architecture’s riddles to expose the culprit and the tragic past driving the killings.
