Gromek and his motorcycle are then buried. The taxicab driver (Peter Lorre Jr., uncredited) who drove Armstrong to the farm, however, reports on Armstrong's behavior to the police. Visiting the physics faculty of Karl Marx University in Leipzig, Armstrong's interview with the scientists ends abruptly when he is questioned by security officials about the missing Gromek. The faculty try to interrogate Sherman about her knowledge of the American "Gamma Five" anti-missile program, but she refuses to cooperate and runs from the room, even though she has agreed to defect to East...
