The murder investigation narrowed to three suspects who were recent arrivals at the nearby inn. Conan deduced the culprit and the cause of the murder. He confronted the culprit at the murder site, but a shock waited him, Ran and Sonoko - the culprit was not alone! The culprit was a yakuza lieutenant who brought henchmen far too numerous for Ran to deal with alone. Makoto arrived in the nick of time, he and Ran fought them off until the police arrived.
