Dietrich travels to Hamburg, Germany, where he undergoes six months of intensive training in espionage. He is then sent back to the United States to set up a radio station and to act as paymaster to the spies already there. He is told that only a Mr. Christopher has the authority to change his assignment.Dietrich manages to pass along his microfilmed credentials to the FBI they are altered so that instead of being forbidden to contact most of the agents, he is authorized to meet them all. In New York, his contact, dress designer Elsa Gebhardt Signe Hasso, is suspicious of the modification and requests confirmation from Germany, but communication is slow. In the meantime, she has no choice but to give Dietrich full access to her spy ring. When questioned, Dietrichs other legitimate contact, veteran espionage agent Colonel Hammersohn Leo G. Carroll, denies knowing Mr. Christophers identity. ........
