Meitantei Conan

Synopsis

Conan catches Ran leaving to go on a date, supposedly with Kudo Shinichi. Conan, knowing it's a lie, follows her to a coffee shop where she admits to be waiting for someone else important. Ran leaves to buy some cake for Conan who stays at the coffee shop. A woman named Himeno Yayoi is found murdered in a bathroom stall; the four people who came in around the time Yayoi did, Wakaoji Shiro, Sumeragi Yuichi, Tonoyama Juzo, and Kisaki Eri are suspects to the crime. The police arrive and assume the criminal crawled above the bathroom stall to leave the scene, cutting down the suspects to two people. Conan notices that there's blood on top of the stall. He realizes how the murder occurred and drops subtle hints. Suspect Kisaki Eri (who Conan thinks is vaguely familiar) picks up on the hints naming Juzo the murderer. She reveals that Juzo strangled Yayoi, threw her over the stall, tied a rope to a knife and stabbed her, and pulled his knife back after he threw her over the stall. As evidence, Conan notices the bandages around Juzo’s fingers have been tied around different fingers, showing the bandages were used to strangle Yayoi and were tied to the knife to throw it over. Juzo killed Yayoi in order to keep his affair with her a secret from his wife. Eri is revealed to be Kogoro’s ex-wife and Ran's mother; Conan then remembers how she used to scold him and Ran.
