第 107 集: Matthew Kohler 尋求協助尋找失蹤的妹妹 Celia，懷疑是 Walter Rivers 所為的謀殺案。

107

Matthew Kohler, a co-star of the Masked Yaiba show, has come forth to Richard asking for help to find his sister Celia, who he believes was murdered and buried in the backyard of a man named Walter Rivers, Celia's last client before she disappeared. He suggests they dig around when Walter leaves for his Saturday treatment at a local hospital. Unfortunately, Richard declines due to a lack of evidence that a crime had been committed. The Junior Detective League, having already met Walter once attempting to get their baseball, goes to Walter's house to stop Matthew should he decide to take matters into his own hands, but they are shocked to learn that he is in police custody after just robbing a jewelry store. Conan wonders why Matthew left his getaway car where it could be spotted easily, why he didn’t bother covering his face, and notes the manhole near Walter's house and the construction site.
