Meitantei Conan

Synopsis

Okida, CEO of a computer software company, is found dead from a heart attack. Conan finds it strange that Okida was sweating a lot before his death, and that flowers that had been delivered the day before had already wilted. Conan notices that Tokito, Okida's driver, is the only one with a motive to murder him. Tokito once owned a computer company himself but signed everything over to Okida, who berated and humiliated Tokito whenever the opportunity presented itself. Conan realizes that the heart attack was caused by thermal shock in a short period of time, noting the dead flowers and solidified chocolates. Using the voice changing bow-tie, he uses Kogoro and Inspector Joseph Megure‘s voices in order to have them meet at Tokito's house where Conan drops subtle hints to reveal Tokito as the murderer. Using the evidence that Tokito took Okida's cat home with him that day, Tokito confesses to murdering Okida by hacking the computer that regulates the houses temperature and turns himself in.
