gives Schlager the information and receives $50 a month, Mrs. MacLaughlin's address, and a list of new objectives. Kassel is called back to Germany. He takes his mistress, Erika Wolff, and leaves his wife behind. The narrator provides a dramatic description of the fascist way of life. Kassel is put in charge of all Nazi activities in the United States. Under the slogan, "America for Americans," the country is swamped by propaganda while spies target military operations. Thanks to the postman's curiosity, British Military Intelligence uncovers Mrs. MacLaughlin's role as postmistress for a worldwide network of spies. (In a moment that is chilling in hindsight, one letter is from Japan.) American military intelligence in New York consists of Major Williams and one assistant. Williams turns to the FBI for help, although it has never played that role before. FBI Agent Ed Renard takes the case. Kassel visits Camp Horst Wessel, where German-American children are trained in Nazi ideals and military skills. Schneider uses an alias to obtain passports, arousing suspicion. The FBI follows the package and arrests him. Knowing his true identity, they realize that they have a letter that he sent to MacLaughlin. Renard flatters his ego for hours and extracts a detailed confession. Through Schneider, Renard finds Wenz, Kleinhauer and Kassel. Kassel proudly shows Renard his files on important Americans that document racial impurity. He tries to burn the code key, but Renard stops him. Renard confronts him with Kleinhauer, who confirms his link with Schlager. When Renard reveals that he knows about Erika, Kassel confesses everything about the German spy organization, revealing the intricacy and scope of the network. He is released, and the Gestapo are waiting. He swears that he revealed nothing, but the men are arrested outside his apartment building. A federal dragnet captures many agents and their accomplices. On March 13, 1938, Hitler annexes Austria. Renard warns Kassell's wife that the Gestapo men have made bail. Karl returns home from meeting Erika and lies to his wife. He packs, refusing to take her with him. She does not warn him. The Gestapo capture him and take him to the Bismarck. In Germany, he is told to claim that he was tortured. In New York, Hilda receives the same instructions. Eighteen people are indicted. Four are in custody: Schneider, Wenz, Kleinhauer and Helldorf.
