[DeepL Translation - needs review] A student guidance teacher has died of cyanide poisoning in the school locker room. A problem child who invites the teacher on a private trip, a beautiful and intelligent girl, the head of the kendo club, and the head of the archery club who picks up the teacher - the candidates for the murderer appear one after another. And then there is a second murder at a field day costume parade ....... A coming-of-age mystery that won the Rampo Award.
