第 408 集: 柯南與平次破解鏡子走廊的幻覺，揭發道爾為兇手。
Conan recreates the trick used by the killer, disappearing and reappearing in front of everyone in the creepy long hallway. It is revealed that Tenko's corpse was there the entire time, and Heiji shows that it involves how the house is built. They reveal the hallway has mirrors on the doors with identical rooms on the side, topped off with a projector screen to cause an illusion. Dogo is revealed to be the murderer, evidenced by his under clothes stained with Tenko's blood. Dogo confesses that Tenko stole Mr. Masakage's trick, her new trick, "Return of the Witch", is a rip-off of their mentor's "Return of the Devil." Tenko's blatant disrespect and sense of arrogance drove Dogo to murder her, and Mari knew Dogo had a hand to play in Tenko's murder but didn't say anything. Dogo is arrested for murder.
