Plot
Part 1
The Detective Boys are stranded on a mountain when Agasa's car breaks down. Seeking shelter from the rain they come across a villa where piano music was heard and enter the house when their calls are unanswered. Inside, they explore and discover a diary on the table confessing to a plan of a kidnapping and murdering a boy; a blackout then occurs due to the storm. They find a small coffin planned for the murder and realize its empty and the possibility the boy is still be alive. At that moment, piano music is heard again. Conan assures them it will be safe to search the house as the culprit is playing the piano. Ayumi wanders off on her own and finds a photo of a family and a room with water leaking out of it.
Part 2
Realizing the piano playing they hear is a recording, they enter the piano room. Conan notices the piano chair was set to a child's height and deduces where the boy is. He has the Detective Boys sing a song in the piano room and catches the boy watching them and befriends him. The boy, Keita Onoda, is a piano prodigy to which the kidnapper abducted to allow his daughter to win a piano competition. Conan also reveals the dairy entry is out of order due to Keita's tampering and that the kidnapper felt increasingly guilty as the days went on. After reading the last page in the dairy, they realize the kidnapper plans to suicide in the bathroom and manage to save him. In the aftermath, Keita's mother does not push charges due to Keita's defense. The kidnapper's daughter meanwhile, revealed she skipped the piano competition as she was worried about Keita's disappearance.
