I’ll be careful not to give away any spoilers and make her dislike me.” (Shibuya, Hakubundo Main Bookstore) At the beginning of each chapter, there’s a “theft request.” We recommend parents and children have a game of guessing who, why, and how! An urban legend of a “legendary thief” whispered about in the seaside town of Umineko. He only takes requests from the children of Umineko Town, and his targets are often worthless items like broken toys and old tools!? Hisato, a sixth-grader, and his cousin Ken investigate the mystery of this strange thief. Just then, the recycled library book Ken had acquired was stolen! The crime scene was Hisato’s living room. It happened in the blink of an eye, when everyone took their eyes off their books. Hisato, Ken, and their classmate Kaori pursue the mystery of the phantom thief. As if to mock the three, one theft after another occurs! Why are worthless items stolen? Can you uncover the shocking truth? Episode 1: The adventure begins! Episode 2: Steal a Deleted Book from the Library Episode 3: Steal a Drumstick Episode 4: Steal an Out-of-Season Carp Streamer Episode 5: Steal the Broken Toy Author: Tatsumi Atsuga Tatsumi) Kodansha’s “Aoitori Bunko” series, featuring authors like Hayami Kaoru and Matsubara Hideyuki, was what got me into mystery novels. So, I’d always wanted to write a novel to introduce children to mysteries, and when I received the idea for this “Mystery Library” project, I thought, “I have to do it here!” (From the author’s message on the “Mystery Library” website)
