The File of Young Kindaichi (1997 ) Episode 22

The club members begin to fear for their lives but cannot leave the island because of an approaching typhoon. The next morning, student Harumi Kiryu is found dead, hanged from a tree in an apparent suicide, but Hajime proves she was murdered. Then, after she almost discovers someone in the sound room of the theater, teacher Natsuyo Ogata is found dead in a bathtub, in a replay of the plot from Phantom of the Opera. However, Hajime deduces that she was murdered elsewhere and placed in the bathtub. Student Ryoko Saotome's reaction to another death prompts her to confess that she, Kiryu and Hidaka had accidentally caused Fuyuko's disfigurement. Hajime later finds Fuyuko's diary in the kitchen in which she wrote about loving "R". Suddenly someone wearing a phantom mask, apparently Kagetsu, attacks Saotome and Miyuki. When Hajime runs into the room Kagetsu jumps from the window into the ocean and apparently dies, but Hajime is suspicious. He realizes that it was a trick to make them believe Kagetsu died from the fall.
