Ep. 42: Karaoke Box Murder Case involves pop star Kimura Tatsuya’s cyanide poisoning death.

42

Sonoko invites Ran and Conan to a karaoke bar to meet pop star Kimura Tatsuya of the band Lex, alongside guitarist Shibazaki Mieko, manager Terahara Mari, and drummer Yamada Katsumi. Tatsuya displays an arrogant personality while performing his song "Bloody Venus." Former member Sumii Go delivers food, and Tatsuya collapses after eating a rice ball. Conan detects cyanide and deduces murder. He examines a photograph showing Tatsuya, Katsumi, and two women, one identified as Mari despite her altered appearance. Using Shinichi’s voice, Conan explains that cyanide coated Tatsuya’s jacket, which transferred to his hand when he removed it, and subsequently to the rice ball. The killer is revealed to be Mari, who switched jackets to hide evidence and possessed Tatsuya’s lighter. She confesses that plastic surgery strained their relationship, but Tatsuya actually loved her original appearance. A love song on the photograph’s back reveals his true feelings, causing Mari to weep in regret.
