Episode 10

Investigation Team 1 is called to a scene where a middle-aged man is found at the bottom of a 4m pit. They see it as an accident and assign the case to Sgt. Nogawa, the Takuma investigation team's liaison. He brings them in, and Takuma finds a stick nearby. The victim,Tomoyuki Itano, was walking his dog before going to bed, as usual, as seen in a security camera video. The stick was thrown to the dog by someone out of camera coverage. A playing card found in Itano's wallet has the first character of his name on it, along with an aphorism. Autopsy results show that a blow to the head and not the 4m fall killed Itano. Thus begins "Mayhem at the Toy Company."
