[DeepL Translation - needs review] Takuichi Samejima was invited to the company chairman's villa for three days and two nights because his hobby is reading. He was told by the well-wishers who were waiting for him that there must be a rare book in the mansion, but he could not find it even after searching for more than 10 years. This is a gem of a mystery about a book that was allowed to be lent to only one person for only one night.
