Takuichi Samejima was invited to the company chairman’s villa for three days and two nights because his hobby is reading. He is told by the elegant but strange people of the elderly who are waiting for him that there is a scarce book, “March in the Crimson Abyss” which is supposed to be in the villa, but has not been found even after a search for more than 10 years. This is a gem of a mystery surrounding a book that was allowed to be lent to only one person for only one night.
