23

On closer examination of the videotape, it appears that someone else was also in the warehouse before Dr. Kobayashi was killed. The ambitious Hospital director Terao appears to be the only one to benefit from the deaths. On their way to question Terao, his water mill house explodes with him inside. Sakon believes that he knows the killer, and catches and confronts Numata Mitsuru who is still alive after faking his own death. With these events, and the sight of a Takayama doll, Tsukiko recovers her memory, but has no recollection of recent events and is protected from the knowledge of her former fiance Mitsuri's murders.
