Ep. 331: Kogoro, Ran, Sonoko, and Conan seek shelter during a rainstorm and discover a suspicious death.

Kogoro, Ran, Sonoko, and a sick Conan meet tennis instructor Hiroto Akashi while on a trip to play tennis. It starts to rain heavily and their van is washed away, forcing the group to take shelter at Hiroto’s house nearby. Hiroto introduces his adoptive father, Iwao, to everyone and has made spicy curry for dinner. When Ran goes to get Iwao’s plate, she hears a muffle sound and goes back to the living room. She goes back a second time, at Hiroto’s request, but finds Iwao hanging in his room, bleeding from his mouth. Inspector Yamamura is called to investigate; both he and Kogoro conclude that Iwao took his own life. Hiroto is considered the prime suspect, but he was washing dishes and witnesses to back his claim. Conan gets involved and finds a napkin with bite marks on it, a knotted lamp string, thin marks on Iwao’s wrists, and something missing from the incident.
