The Novelist Known as the Demon King Conan and Kogoro are walking through the residential area of Yonehana Town when they see a crowd of police and onlookers in front of a mansion. It is the home of Shintaro Tabun, a successful writer, where a body has been found shot to death. A rifle was found in his study, but there were no witnesses. His disciples, Naoya Akaike and Miyuki Izukawa, were the first to discover the body. There were four other disciples, including Ryunosuke Oto and Haruo Chigasaki. As we listened to their stories, we found out that Tabun's works were written by his disciples, and that they had a grudge against him.
