After missing their return boat, Kogoro, Ran, and Conan accept a ride from the wealthy Hatamoto family on their private vessel. The group includes clan head Hatamoto Gozo, his granddaughter Hatamoto Natsue, Natsue's husband Hatamoto Takeshi, Natsue's sister Hatamoto Akie, Akie's husband Hatamoto Tatsuo, his second son Hatamoto Joji, his grandson Hatamoto Ichiro, his eldest daughter Hatamoto Mariko, Mariko's husband Hatamoto Kitaro, and butler Suzuki Kenji. Gozo humiliates Ichiro while he sketches and privately meets Takashi, who is revealed to be the son of Edward Zimmers, a man Gozo ruined financially. That night, Gozo is murdered, and a bread crumb is found in his blood. Takashi, the only suspect with a motive, is locked in a cabin. The family learns Natsue inherits everything, shocking them. An enraged Tatsuo leaves but is found brutally murdered, and Takashi disappears from the storage room. Kogoro concludes Takashi escaped to continue killing.
