While at a camping trip, The Detective Boys are surprisingly greeted by Masumi Sera. While the Professor sets up camp and Conan chats with Sera, Ayumi, Genta, Haibara, and Mitsuhiko venture into the woods and come across a man burying a body.
Inspector Yamamura arrives to the scene of the body, and later has three suspects. The only clue is a dying message of her fingers being in an odd form behind her back.While the children run, Haibara alerts the police, and then they hide in a dark cabin, only to figure out it is where the culprit was earlier. To prevent them from talking, the culprit locks them in and sets the cabin blaze.
The culprit is Chouzou Usagi. The woman was Chouzou's girlfriend and a kindergarden teacher. The dying message was her fingers in the shape of a rabbit ([兎]usagi) shadow puppet. He killed her because she stuck him in a small dark cabin with her despite his claustrophobia. She was trying to cure him of it when Chouzou had a panic attack and killed her. He then states he trapped the Detective Boys in the cabin and set it on fire. Haibara uses an antidote she prepared to become Shiho Miyano and save the others. Mitsuhiko later sends a picture of Shiho Miyano "Sherry" to Kogorou to find her and say thanks and also shows the picture to Sera. Amuro and Subaru Okiya hack Kogorou's computer to find the image, with Sherry wearing a Mystery Train ring. The events that follow occur later in the Mystery Train case where the Black Organization returns to kill Sherry.
