Synopsis: Kogoro is invited by a famous fortune teller named Reika Shijo for an interview. Ran asks Shijo to read her fortune; Shijo tells her she will read it later and gives Ran her room key's diamond keychain as compensation. Later that evening, Shijo's guests realize she has been in her room for far too long. Unable to open her door, they see her through the outside window dead. One of her guests, Kensuke Katsuragi, climbs to the top of Shijo's room and breaks through the glass ceiling and unlocks the door. The police arrive and their investigation reveals that Shijo's room contained a specialized key which could not be copied. Conans investigates and after finding a few clues, tranquilizes Kogoro and impersonates his voice to reveal Kensuke Katsuragi to be the culprit. Conan reveals that Katsuragi met with Shijo in her room and murdered her. After doing so, he took the key to her rooms, locked it, and climbed from the outside to the top of Shijo's room, cracked a small piece of the ceiling, and dropped the keys into the room. As evidence, Conan reveals that despite the key being mixed in a pile of other keys, Katsuragi was able to find out which key opened the door in his first try. Katsuragi replies that he knew the key with the sapphire keychain was the one for the door; Conan reveals that the key was originally connected to a diamond keychain which is now in Ran's possession. This means that Katsuragi was the last person to meet Shijo before her death. Katsuragi confesses revealing that Shijo was extorting money from him. After the police arrest Katsuragi, Conan ask Ran what she wanted Shijo to read for her to which she replies Shinichi's current whereabouts.
