S01E672: Detectives' Nocturne (Kidnapping)

Arriving at Katshitsuka's home, Ran receives a phone call from Masumi. The phone call receives noise which Tooru deduces to indicate the house is bugged. While Kogoro, Ran, and Tooru investigate the house, Conan notices Katshitsuka sneaking out and accompanies her for a drive. Meanwhile, Tooru finds a dead man in the apartment and realizes he was the one actually living there. Meanwhile, Katshitsuka drugs Conan to sleep and sends a ransom to Kogoro to prevent him from calling the police. The three at the apartment discover the victim has recordings of a recent bank robbery indicating he was related to it and that the victim of the bank robbery, Kenya Shouno, was the man in the picture with Katshitsuka. Ran tells Agasa to use the tracker to find Conan. Agasa, Haibara, and Subaru proceed to follow the signal. Meanwhile, Masumi also decides to search for Conan.
