Episode 243: Kogoro Mouri's Imposter (Part 1)
Scenario: Tatsuo Mori, a Mori Kogoro impersonator, arrives at the Aoiya Hotel near a creepy forest where he is invited to investigate a case where a long-haired man is said to have committed suicide 4-5 years ago. The real Kogoro, with Ran and Conan, is heading there as well and runs into Detective Yamamura who explains the case; the man who committed suicide was wearing a winter coat but died in the summer, had keys, but no driver's license, and cigarettes but no lighter. Kogoro says he was hired by Yoshiro Onda, the hotel's owner to search into the matter. After a brief investigation, they head to the inn where Kogoro bumps heads with his imposter and meets Eiji Urakawa and Masao Jinbo, who gives Ran her cell phone. He decides to play along and not reveal his identity. Later that night, Tatsuo is found hanging in his room.

Kogoro goes there without knowing about the double. On the way the trio is picked up by Detective Yamamura. Yamamura tells them about a man who committed suicide four-five years ago. There were a lot of strange things about the body. It had car keys, but no drivers license, cigarettes, but no lighter, and it was wearing a red winter coat, despite that a recipe, proved that he died in summer. Kogoro explains that the inn owner has hired him to investigate a mystery. Five years ago a long-haired man wearing a red coat arrived and paid the owner to keep a letter and a briefcase for him for a year. The instructions were that if the long-haired man came back, he should give him the briefcase, if someone else comes, the owner shall give him the letter. The day after another man came and ask for the briefcase. The owner gave him the letter as told to, and the man became mad upon reading it, torn it to pieces and left and was never seen again. The owner pieced together the letter, on which were written in red 'I kill you with my curse'. When they all arrive, they learn of the double. Kogoro is first enraged, but then he decides to play along and not reveal his identity. Later that night, Tatsuo is found hanged in his room.
