In the mid-1930s, just as the United States was embarking on a policy of neutrality, Nazi Germany launched a program of espionage against the unwary nation. Rhodri Jeffreys-Jones’s fascinating history provides the first full account of Nazi spies in 1930s America and how they were exposed in a high-profile FBI case that became a national sensation.

The first full account of Nazi spies in 1930s America and how they were exposed. In the mid-1930s just as the United States was embarking on a policy of neutrality, Nazi Germany launched a program of espionage against the unwary nation. The Nazi Spy Ring in America tells the story of Hitler’s attempts to interfere in American affairs by spreading anti-Semitic propaganda, stealing military technology, and mapping US defenses. This fast-paced history provides essential insight into the role of espionage in shaping American perceptions of Germany in the years leading up to US entry into World War II. Fascinating and thoroughly researched, The Nazi Spy Ring in America sheds light on a now-forgotten but significant episode in the history of international relations and the development of the FBI. Using recently declassified documents, prize-winning historian Rhodri Jeffreys-Jones narrates this little-known chapter in US history. He shows how Germany’s foreign intelligence service, the Abwehr, was able to steal top secret US technology such as a prototype codebreaking machine and data about the latest fighter planes. At the center of the story is Leon Turrou, the FBI agent who helped bring down the Nazi spy ring in a case that quickly transformed into a national sensation. The arrest and prosecution of four members of the ring was a high-profile case with all the trappings of fiction: fast cars, louche liaisons, a murder plot, a Manhattan socialite, and a ringleader codenamed Agent Sex. Part of the story of breaking the Nazi spy ring is also the rise and fall of Turrou, whose talent was matched only by his penchant for publicity, which eventually caused him to run afoul of J. Edgar Hoover's strict codes of conduct.

An account of a virtually unknown pre-World War II counterespionage operation describes how naturalized German-American agent William G. Sebold became the FBI's first double agent and was a pivotal figure in the arrests of 33 enemy agents for the Nazis.

NEW YORK TIMES BESTSELLER • Turn: Washington’s Spies, now an original series on AMC Based on remarkable new research, acclaimed historian Alexander Rose brings to life the true story of the spy ring that helped America win the Revolutionary War. For the first time, Rose takes us beyond the battlefront and deep into the shadowy underworld of double agents and triple crosses, covert operations and code breaking, and unmasks the courageous, flawed men who inhabited this wilderness of mirrors—including the spymaster at the heart of it all. In the summer of 1778, with the war poised to turn in his favor, General George Washington desperately needed to know where the British would strike next. To that end, he unleashed his secret weapon: an unlikely ring of spies in New York charged with discovering the enemy’s battle plans and military strategy. Washington’s small band included a young Quaker torn between political principle and family loyalty, a swashbuckling sailor addicted to the perils of espionage, a hard-drinking barkeep, a Yale-educated cavalryman and friend of the doomed Nathan Hale, and a peaceful, sickly farmer who begged Washington to let him retire but who always came through in the end. Personally guiding these imperfect everyday heroes was Washington himself. In an era when officers were gentlemen, and gentlemen didn’ t spy, he possessed an extraordinary talent for deception—and proved an adept spymaster. The men he mentored were dubbed the Culper Ring. The British secret service tried to hunt them down, but they escaped by the closest of shaves thanks to their ciphers, dead drops, and invisible ink. Rose’s thrilling narrative tells the unknown story of the Revolution–the murderous intelligence war, gunrunning and kidnapping, defectors and executioners—that has never appeared in the history books. But Washington’s Spies is also a spirited, touching account of friendship and trust, fear and betrayal, amid the dark and silent world of the spy.

A 2018 FINALIST FOR THE PULITZER PRIZE “[Hitler in Los Angeles] is part thriller and all chiller, about how close the California Reich came to succeeding” (Los Angeles Times). No American city was more important to the Nazis than Los Angeles, home to Hollywood, the greatest propaganda machine in the world. The Nazis plotted to kill the city's Jews and to sabotage the nation's military installations: Plans existed for murdering twenty-four prominent Hollywood figures, such as Al Jolson, Charlie Chaplin, and Louis B. Mayer; for driving through Boyle Heights and machine-gunning as many Jews as possible; and for blowing up defense installations and seizing munitions from National Guard armories along the Pacific Coast. U.S. law enforcement agencies were not paying close attention--preferring to monitor Reds rather than Nazis--and only attorney Leon Lewis and his daring ring of spies stood in the way. From 1933 until the end of World War II, Lewis, the man Nazis would come to call “the most dangerous Jew in Los Angeles,” ran a spy operation comprised of military veterans and their wives who infiltrated every Nazi and fascist group in Los Angeles. Often rising to leadership positions, they uncovered and foiled the Nazi's disturbing plans for death and destruction. Featuring a large cast of Nazis, undercover agents, and colorful supporting players, the Los Angeles Times bestselling Hitler in Los Angeles, by acclaimed historian Steven J. Ross, tells the story of Lewis's daring spy network in a time when hate groups had moved from the margins to the mainstream.

After Hitler annexed Austria in 1938, the Gestapo began silencing critics. Many were shipped to concentration camps; those deemed most dangerous to the Reich were executed. Yet a few slipped through the Gestapo's net and organized resistance cells. One group, codenamed CASSIA, became America's most effective spy ring in Austria during World War II. This first full-length account of CASSIA describes its contributions to the Allied war effort--including reports on the V-2 missile, Nazi death camps and advanced combat aircraft and tanks--before a catastrophic intelligence failure sent key members to the guillotine, firing squad or gas chamber.

Leon Turrou was the FBI agent closest to the Nazi spy ring in America in the late 1930s. His leaks to the American press and the book he was allegedly writing led to him being fired from the Bureau by J. Edgar Hoover. But he did publish his book, this book, and then Hollywood made a movie of the case that starred none other than Edward G. Robinson. Turrou was one of America's original whistleblowers.
