Ep. 11: Moonlight Sonata Murder Case
Aired on April 8, 1996

11
Kogoro, Ran, and Conan visit Tsukikage Island after pianist Asoh Keiji hires them. They learn Keiji died twelve years ago, allegedly killing his family before burning his estate while playing Beethoven. His piano sits in the community hall, where former mayor Kameyama Isamu was previously found dead with the same melody playing. During Isamu’s funeral, Kawashima Hideo is found drowned, and the song plays again. Conan suspects more murders are coming. Police reveal Keiji had a son, Seiji, who survived because he was in a Tokyo hospital. The next day, during interrogations, the second movement of the sonata is heard, and current mayor Kuroiwa Tatsuji is stabbed to death in the PA room.
