Kindaichi Shounen no Jikenbo EP31 - Ghost Ship Murder Case File 4

Hajime now accuses the young crew member Yoko Katori of being the killer, saying that Kentaro Otsuki grabbing Mizuzaki was part of his plan to expose her. He claims that Takamori, Wakaouji, Kanou and Akai were all involved in the sinking of the Orient, and that Katori and Tokihara were somehow related to victims. Yu Tokihara admits that she wanted revenge because she saw Wakaouji jeopardize her husband to save himself. However, she could not kill him, and after he apparently suicided she no longer had a reason to live. Yoko Katori says that Akai's article about the sinking alleged that her father, the captain of the tanker, was drunk and he was assigned blame for the collision, but she maintains that he did not drink. Hajime then explains how Yoko committed the murders. Suddenly, Mizuzaki breaks down and admits that he was also on the Orient, and was responsible for the collision because he joined Captain Wakaouji at a party. Wakaouji, Takamori and Kanou then lied to cast the blame on the tanker captain to save their careers. Yoko is arrested for the murders, however her father's name is finally cleared. Mizuzaki and Yoko still love each other, and he promises to marry her on her eventual release from prison.
