The House of Crooked Walls

Japan, Christmas 1983. Wealthy industrialist Kodaburō Hamamoto gathered friends and acquaintances in his mansion. The guests are astonished by his house – a whimsical structure with numerous rooms, slanted floors, and staircases leading nowhere, with a “falling” tall tower reminiscent... of the Leaning Tower of Pisa. They all admire the owner's imagination and prepare to joyfully celebrate Christmas.
But their expectations are not destined to come true. Because on Christmas Eve, a murder occurs in the house. The chauffeur of one of the guests dies from a knife wound. The urgently summoned police are completely bewildered. For the murder could not have been committed – all circumstances and conditions are against this. Moreover, no one has a motive…
While the inspector and his assistants are scratching their heads, and the guests are in a daze, another even more incredible murder takes place in the house. Contacting their superiors, the stunned police learn that a person capable of finding the criminal is on their way. This is – an astrologer and fortune teller from Tokyo, Kiyoshi Mitarai. And only he alone is able to unravel this mind-boggling puzzle…
You will have all the necessary keys. But will you be able to find the answer before the detectives do?
