(from ebookjapan): Published in 1960, this is the mangaka's first full-length work, and it is a major work that spans two books, the first part and the second part. Part 1 - The story revolves around a secret hidden in a doll owned by the main character, and is a dramatic story that keeps the reader's hands sweating. Part 2 - The story takes place in Tokyo, Kyushu, and a hot spring resort deep in the mountains, all at a brisk tempo.
