Kodansha Bunko, Price including tax: 858 yen (current new purchase price) Although there is some minor unevenness on both the front and back covers, I don't think there are any noticeable folds, tears, scratches, snags, or discoloration. Also, there are no markings or writing whatsoever. I watched part of a TV show based on this series recently and was intrigued by the seemingly interesting story, so I obtained and read the book. I believe the main theme is an unsolved kidnapping case, but it doesn't just end there. It's a well-crafted work that intricately emphasizes the mystery by involving many people, such as the ransom collection and the intervention of a third party who caught wind of it. I was also moved by the victims' couple's grief over losing their child and the sadness of the children who were caught up in the adults' machinations. In my eyes, it's a high-quality work that includes various themes. If you are interested, please feel free to purchase! Immediate purchase without comments is welcome.
