Ep. 72: Serena invites Conan and Rachel to her villa where a murder occurs involving her brothers and their father.

Serena invites Rachel and Conan to her family's villa during the summer, where they meet her sister Angie's fiancée, Tod Appenheimer, and his baseball obsessed father, Rodrick, who expresses disdain over his sons' ways of life. Later that night while returning to his villa after watching a baseball game, Rodrick is brutally beaten to death and his watch stolen, allegedly by Todd. Conan and the others witness this. The next day, Tad and Ted, Tod's brothers, arrive, revealing them to be triples. Only Tod's has an alibi since he was talking to someone on the phone using a groundline, leaving his brothers prime suspects. Using Serena, Conan reveals that Ted, the novelist brother, killed Rodrick. He wiretapped his father's watch to track his movements, explaining why it went missing and made the mistake of setting the answering machine's clock ahead to the time of the blackout; no messages could have been recorded then. Defeated, he explains that he needed inspiration to continue his work, and since every writer has had a great tragedy in their lives, he needed to experience one himself.
