Detective Conan: Detectives' Nocturne (The Case)

Overview

Kogoro prepares to meet with the client Kei Katshitsuka. While waiting, he receives mail of Katshitsuka who changes their meeting location to a local restaurant. There, Kogoro realizes the cell phone address is different from the first message he received from the client. He, along with Tooru, Ran, and Conan return to the agency where they discover Katshitsuka tied up with her kidnapper dead. The police arrive and determine the kidnapper killed himself since no gunpowder was found on Katshitsuka. The four accompany Katshitsuka home; during the ride, Conan ponders on why the kidnapper's wallet was full of coins and small bills, his cellphone having only a history of one message and the lack of gunpowder on Katshitsuka.
