her sudden departure. Norberg tells Ted that he plans to experiment on a monkey's head, keeping it alive, with a clear plastic dome over its cranium so that he can observe its brain function, then transfer what he learns to humans. Ted readily agrees to help. But then Norberg unexpectedly has the opportunity to use a human head, for Karl had drugged Elsa and taken her to the laboratory, not the train station. Norberg and Karl find Elsa dead in the lab, with Prisoner no. 3 standing over her body, smiling. Norberg later impresses Ted with a wall of amputated human arms, which he can control through electrical stimulation. After Ted agrees to tell no one of what he is about to see, Norberg trustingly shows him Elsa's head, alive, its skin a horrid blue color and its brain covered by a clear plastic dome. That night, Jean has a nightmare. She tells Ted that she has dreamed that Elsa is dead and that her head is in the laboratory. To keep from further upsetting her, Ted dismisses it as just a bad dream. In truth, Elsa's head is communicating telepathically with Jean as she sleeps. Not knowing this, Jean persists in trying to find her friend, consulting railway station personnel and a Mrs. Smith (Ann Tirard), who may know something about Elsa's whereabouts. Mrs. Smith denies any knowledge of Elsa, but she is, in reality, Mrs. Schmidt, another Nazi living undercover in England. Jean does not discover this and asks Police Inspector Witt (Tom Chatto) to investigate. After seeing Elsa's head, Ted wonders about Norberg's real intent. As he walks toward the lab, Karl knocks him unconscious. When he comes to, Norberg tells him that he was attacked by Norberg's brother, whom Norberg describes as having been "mentally ill" since the war. He asks Ted not to tell Jean, as no. 3 is her father and she has believed since childhood that he died in a concentration camp, not a Nazi but a victim of the Nazis. Lubeck and Tirptiz torture Karl to find out if he has told anyone about their plot. He confesses that he has told the Schmidts, who are members of his own family. After Karl tries to prove his loyalty to the Nazis by attempting to murder Jean and Ted, Lubeck forces Norberg to freeze Karl as punishment. Norberg tries to demonstrate to Lubeck
