44

When Kogoro, Ran and Conan are on the way to work on a case, they pick up Hotta Kosaku whose having car troubles on the side of the road. In return for the ride, Kosaku invites them to his birthday party where they meet Hotta Ryoji, Hotta Koichi, Hotta Harumi, and the groundskeeper Yamauchi Masahiro. Hotta Fumiko, Kosaku’s estranged daughter, makes an appearance and Kosaku quickly dismisses her. An argument leads Kosaku to excuse himself to his room, where he is killed when a massive explosion occurs. Fumiko denies involvement but is happy to see her father dead. Conan investigates and determines the bomb was homemade after Kosaku’s corpse is found covered in fertilizer. Kogoro is put to sleep and Conan declares the groundkeeper Masahiro to be the killer as he is the only one with access to chemicals and also possesses skills to engineer a bomb strong enough to destroy one room and kill one person. Masahiro confesses saying that his son, who was a pianist, was driven to suicide by Kosaku because when Kentaro asked for his permission to date his daughter Fumiko he broke Kentaro's hand in response which made him unable to play piano anymore. Masahiro was planning to murder Fumiko, who he sent a fake invitation to, but that failed when Conan warned her of the situation. (Source: Wikipedia)
