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.

Can you keep a secret?

Maybe you can, but the United States government cannot. Since the birth of the country, nations large and small, from Russia and China to Ghana and Ecuador, have stolen the most precious secrets of the United States.

Written by Michael Sulick, former director of CIA’s clandestine service, Spying in America presents a history of more than thirty espionage cases inside the United States. These cases include Americans who spied against their country, spies from both the Union and Confederacy during the Civil War, and foreign agents who ran operations on American soil. Some of the stories are familiar, such as those of Benedict Arnold and Julius Rosenberg, while others, though less well known, are equally fascinating.

From the American Revolution, through the Civil War and two World Wars, to the atomic age of the Manhattan Project, Sulick details the lives of those who have betrayed America’s secrets. In each case he focuses on the motivations that drove these individuals to spy, their access and the secrets they betrayed, their tradecraft or techniques for concealing their espionage, their exposure and punishment, and the damage they ultimately inflicted on America’s national security.

Spying in America serves as the perfect introduction to the early history of espionage in America. Sulick’s unique experience as a senior intelligence officer is evident as he skillfully guides the reader through these cases of intrigue, deftly illustrating the evolution of American awareness about espionage and the fitful development of American counterespionage leading up to the Cold War.
