Dancing Demon in the Noh Mask Mansion (Part 2) While awaiting the police, more attempts to murder the museum curator occur. A fire breaks out and the group is locked inside one of the buildings. A woman wearing a mask resembling the conspiring ex-wife kills her two partners. The group manages to escape and calls the nurse over the internal phone to see if she and the curator are safe. The nurse reassures him, but then screams and hangs up. The group runs to the nurse's location and finds a scene with the nurse unconscious, the ex-wife stabbed to death, and the museum curator severely wounded. Inspectors conclude that the ex-wife tried to kill the curator, and that the nurse fought back in self-defense. Sleeping Kogoro reveals the nurse to be the true culprit. The curator survives thanks to Conan's earlier suggestion to wear armor under his clothes.
