Kakuz? shows Kogoro a photograph of Tango's body in a pool and points to a white glove Tango is wearing. He reveals that the glove was the same glove their previous butler wore before a car accident killed him, and that Tango's murder occurred on the anniversary of the butler's death. Kakuz? tells Kogoro that, three days after Tango's death, he received a white glove and now presumes the murderer plans to kill him next. After the discussion, Kogoro and Conan investigate the house searching for clues. When a blackout occurs and the sound of a vase is heard from Kakuz?'s room, they arrive to find him hanged. Conan investigates and realizes three suspicious points: glue was used to keep the knot of the rope together, the broken vase with sweat near the top, and a book titled "Killer of Hades" (in kanji) with blood on it. The police declare that if the book is a dying message, the murderer must be one of the three suspects.
