S1E835 — The Man Who Died Twice (2)

Takarada's wife, Mika, has no alibi, and she becomes the prime suspect in the strangling when material evidence is discovered, meaning Koji will inherit Takarada's fortune. Conan suspects Koji set up Mika and questions him, but it becomes clear that Koji has an alibi. Conan goes over the facts again and gradually closes in on the truth.
