Detective Takagi and Detective Sato come to the detective agency Kogoro Mouri. “Recently, a number of strange incidents have occurred,” the two show Kogoro the materials of the incident. The content of the case was disjointed with marriage fraud, bank murder, burglary … However, these cases have something in common, and the “case plot” is always included in the evidence. According to the statements of the criminals caught, the “crime adviser” sold the crime plan. The two people who found their whereabouts set a white arrow on Kogoro as an advisor on the police side. Hamanaka, a crime advisor who claims to be a “Modern Moriarity,” admits what he has done by saying he is “selling plots of crime novels” and is arrested for abetting crime. Pushed by Detective Sato’s aggression, Hamanaka begins to talk about the case he is involved in, but only the suspect in the plot “Takashi Ishigami Review Plan” is missing.
