User:S261157/Kindaichi Case Files - Volume 1: The Opera House Murders
From Detective Conan Wiki
The Opera House Murders is the first Kindaichi mystery, and the story on which the first anime movie is based. Miyuki corrals Kindaichi into assisting the school drama club in rehearsing "The Phantom of the Opera" at an isolated island hotel. But a killer stalks the high school group, one who can walk across mud without leaving footprints, and it's up to Kindaichi to solve the case, fighting time, weather, and police detective Kenmochi, who fails to take the young man seriously (for the last time).
