Detective Conan: Shinichi Kudo's Written ChallengeTV Show

Ran video-chats with Yukino Mizutani, Kogoro's client who apparently is under domestic abuse and being stalked by her lover, Kensuke Kubo. In the middle of the conversation, Yukino seems to be attacked by Kubo and screams for help. Ran calls Shinichi to Beika Mansion where Yukino lives; rushing there, she bumps into Kubo and later deduces that he is the culprit. However, Yukino is nowhere to be found – her corpse is discovered 6 hours later at a weekly mansion in Saitama, which is 200 km far from Beika Mansion; therefore, it's impossible for Kubo to be the culprit..
