Ép. 75: Meurtre du président d'une société de prêt impliquant un empoisonnement au cyanure et une habitude du pouce

75

Richard is playing Mahjong with his friends, Oscar and Michael, and they call Jonathan Hyde, president of Hyde Finance, to play with them. He accepts but when he doesn't show up, they find Jonathan dead from cyanide poisoning and three of his employees are suspects: Morgan Cartwright, Allison Summers, and Jeremy Janus. The poison was only found on the victim's thumb, money, and door handle. Allison makes tea, and Jeremy, Allison, and Morgan use the bathroom. After finding bleach in the bathroom, Conan stuns Richard and reveals Allison to be the killer. She took advantage of Jonathan's thumb-licking habit and coated the kettle knob with cyanide knowing Jonathan would touch it with his right thumb. The poison was erased with bleach, evidenced by a drop of iodine that disappeared from Allison's handkerchief. Allison confesses how Kurt, her only friend, committed suicide; the I.O.U. loan from Jonathan found beneath his feet. (Source: Wikipedia)
