第 89 集: Richard回顧Stefan遇害前的經過，Conan則揭開兇手使用的梯子與膠帶手法。

89

Richard reviews the events that took place before Stefan's murder. Conan finds a ladder in a closet and cellophane tape stuck to the curtain rack to discover the truth behind the case. Conan stuns Richard to reveal that the killer stole the stake from the memorabilia room by using a ladder as a bridge, a fruit cutter, and rigging the window in advance with a twig. There was no need to walk across the rooftop of the connecting corridor; the killer simply walked down it after obtaining the weapon, murdered Stefan, then used the film projector to lock the door behind them. The killer is revealed to be Jonathan Tradonio. He locked the study door using cellophane tape attached to the knob, over the railing, and when the projector pulls the tape, locks it. Jonathan claimed to hear the projector running before the body was discovered, yet the study door is soundproof; he already knew it was on. Jonathan confesses how Stefan ordered doctors to keep his sick sister Joella's condition stable, which worsen overtime and killed her. Later, Richard says his next client as a thing for Frankenstein.
