"In the 1960s 17 people die of cyanide poisoning at a large party at the Aosawas, owners of a prominent clinic in an ancient castle city on the coast of the Sea of Japan. The only survivor is their teenage daughter Hisako, blind, beautiful, admired by all, but soon suspected of masterminding the crime." --Publisher.
