30화: 명탐정 코난이 변호사 다쓰미 소우헤이의 아내 카즈미 살인 사건을 수사하다

30

Kogoro, Ran, and Conan are meeting with lawyer Tatsumi Souhei at his office inside a hotel. Souhei receives a call from his wife, Tatsumi Kazumi, and a musical melody can be heard from her end of the phone call. After the meeting, Kogoro explains to Conan that he was hired to tail his cheating wife, Kazumi. They walk home and pass by Souhei’s manor which is surrounded by police investigating the murder of Kazumi who was found bound, gagged, strangled to death, and stuffed into a bathtub. Conan finds a staple by the body and suspects Souhei to be the murderer, but Kogoro confirms his alibi, prompting Conan to head back to the hotel. He learns the hotel room beside Souhei's is reserved for guests and also learns the melody from a music box alarm clock is custom made for that hotel. At Kazumi’s funeral, a man named Hirose Shunzou reveals he was her lover. The officers plan to arrest him for the murder of Kazumi, but Conan tranquilizes Kogoro, revealing Souhei to be the killer. After Souhei was done with Kogoro, he murdered his wife who was in the guest room beside him, then placed his wife in a bag and threw her down a laundry chute to the bottom floor. He retrieved Kazumi’s corpse, put it in the trunk, and drove it home where he then placed her body in the bathtub. As evidence, Conan gives Megure a tape of the alarm clock in Souhei's guest room to compare with the recorded phone call; it is revealed to have a missing note and matches with the musical melody in the phone call. Souhei confesses to the murder and reveals Kazumi was blackmailing him for money in order to keep his corrupt deeds as a lawyer hidden. (Source: Wikipedia)
