Takeyori Oikawa claims that the Phantom Thief Kid is targeting his painting which is to be unveiled to the world live that day. The painting is a final part of a set of four. He hires Kogoro to protect the painting from Kid. They place the painting in a secluded room with guards at the door and outside the window. When a black out occurs, the painting is stolen and Oikawa's father, who was in the room, is murdered. While the police speculate how the murder was done and whether Kid is the culprit, Oikawa receives a letter from Kid which claims he will steal the truth of him. Oikawa disfigures the letter to incriminate Kid for the murder and hands it to Conan. Conan who had suspected Oikawa murdered his father is now certain he is the culprit.
