Ep. 161: A murder occurs at Ryusuitei where food is delivered by computer-controlled boats on a stream.

161

Kogoro, Ran, and Conan visit Ryusuitei, a traditional restaurant where meals are served via small computer-controlled boats navigating a stream. A murder takes place, and Conan deduces that the crime required the perpetrator to be alone and utilize the waterway to access the room. He reveals that the killer hid inside the delivery boats to reach the victim. The culprit admits to the act, explaining that he was blackmailed by the victim, who demanded a substantial payment. This motive drove the individual to commit the homicide at the establishment.
