Satomi attempts to leave her room and collapses; she is found holding onto broken Buddhist prayer beads with a black bead four down from the top. Later that night, they discover a letter signed by Miyuki confessing to the crime and is at the abandoned cabin. Conan head there and discovers the cabin covered in gasoline and the inugami running towards it. Conan catches the inugami revealing the fire effect was created by imitation fire clothing with remote-controlled lights. The flaming dog-prints were caused by modified lighters placed on the ground and tied to a wire with a hoop at the end. The dog had a mesh-enclosed charcoal tied to its tail, and when passing over the lighters, ignited them. When the dog retrieved the hoop, the lighter came with it, explaining how the lighters were not found after creating the dog-prints. Heiji points out Tomoaki as the culprit, evidenced by the inugami recognizing him as his master, and Satomi's prayer beads.
