Kogoro wins a horse race with the price money being 100 times the original bet, which turns out to be 1 Million Yen. But he admits that it is a ticket he accidentally picked up. Regardless, they go to the neighborhood sushi restaurant to celebrate. There they meet Wakita who turns out to be proficient in deductive reasoning. He correctly predicts the horse Kogoro bet on just by listening to their conversation. While introducing himself, Wakita says that he is a detective maniac and that he struggles to stay in one place and is constantly moving. He wanted Kogoro to narrate some cases he had solved. It seems that Wakita has a 'bad' eye, much to the suspicion of Conan as an eligible 'Rum' suspect.
