Pottery Class Case

Anime Episode 228-229: The Murderous Pottery Class

File 307 - The Hidden Word

It appeared that Kikuyo had a 10 million yen debt and needed the insurance money to pay it. So, the police staff and Muneyuki started accusing her and as she was about to be taken to the police station, Sonoko was stunned by Conan's stun watch and stopped them. After explaining the trick used and the evidence, Muneyuki gave himself in. It turned out that during Christmas, while Muneyuki was cleaning the things of her late daughter, he found the broken box of the tie her daughter gave to Motoo, her husband. And when he went to the airport, wanting to give the tie to Motoo, instead of seeing a griefing man, he saw a cheerful man together with Kikuyo. Three days later, Sonoko received a picture from Makoto after she sent her tea cup. It turned out that he used it as a vase, thinking that the gigantic tea cup is one. When Ran told Conan to help her take her potato chips, he noticed that she has used her tea cup as a place for stationery. Curious of what she carved in the cup, she too it and saw the words "Stupid Detective" under the cup, there was another carving- "I'll be waiting for you". Conan then gave Ran her chips and was overjoyed as he played his games.
