Leading a Detective Around by the Nose Meitantei Conan : Season 1 Episode 979

A woman named Kanae who says "an important brooch was stolen" comes to Kogoro. Kanae said from the criminal, "I kept the treasure brooch. If you want me to return it, come to the other world. It's a park. However, if you notify the police, the treasure will be disposed of immediately.” Kogoro and Kanae headed to the designated park and found a new letter from the clock that was there. The text and the next place were specified, as if they were watching over their actions. Kogoro thinks that Kanae is being targeted for life because of the word "to that world" in the letter and the danger that often occurs. Kogoro, who had been moved from place to place one after another, remembered a certain incident that he solved two years ago.
