This is the story of Latchmere House, code-name Camp 020, MI5's wartime holding centre where enemy agents were interrogated. Camp 020's extraordinary commandant, Major Robert Stephens, recorded details of over 400 spies, adding his own unique personal observations. Most agents were broken, some turned into double-agents and a few executed for treason.

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.

Agent Zigzag and Operation Mincemeat, two thrilling accounts of World War II espionage, are available together as an ebook—with an excerpt from the New York Times bestseller Double Cross. “Not since Ian Fleming and John le Carré has a spy writer so captivated readers.”—The Hollywood Reporter AGENT ZIGZAG • “Wildly improbably but entirely true . . . [a] compellingly cinematic spy thriller with verve.”—Entertainment Weekly Eddie Chapman was a charming criminal, a con man, and a philanderer. He was also one of the most remarkable double agents Britain has ever produced. Inside the traitor was a man of loyalty; inside the villain was a hero. The problem for Chapman, his spymasters, and his lovers was to know where one persona ended and the other began. Based on recently declassified files, Agent Zigzag tells Chapman’s full story for the first time. It’s a gripping tale of loyalty, love, treachery, espionage, and the thin and shifting line between fidelity and betrayal. OPERATION MINCEMEANT • “Brilliant and almost absurdly entertaining.”—The New Yorker Near the end of World War II, two British naval officers came up with a brilliant and slightly mad scheme to mislead the Nazi armies about where the Allies would attack southern Europe. To carry out the plan, they would have to rely on the most unlikely of secret agents: a dead man. Ben Macintyre’s dazzling, critically acclaimed bestseller chronicles the extraordinary story of what happened after British officials planted this dead body—outfitted in a British military uniform with a briefcase containing false intelligence documents—in Nazi territory, and how this secret mission fooled Hitler into changing military positioning, paving the way for the Allies to overtake the Nazis.

During the Second World War, just under 2000 British citizens were detained without charge, trial or term set, under Regulation 18B of the wartime Defence Regulations. This book provides a comprehensive study of Regulation 18B and its precursor in the First World War, Regulation 14B.

The first three volumes of the series dealt with the influence of intelligence on strategy and operations. Volume 4 analyzes the contribution made by intelligence to the work of the authorities responsible for countering the threats of subversion, sabotage and intelligence gathering by the enemy in the United Kingdom and British territories overseas, and neutral countries. It describes the evolution of the security intelligence agencies between the wars and the security situation in September 1939. This volume reviews the arguments about security policy regarding enemy aliens, Fascists and Communists in the winter of 1939-1940 and during the Fifth Column panic in the summer of 1940. It describes how the security system, still at that time inadequately organized and poorly informed, was developed into an efficient machine and how, with invaluable help from signals intelligence and other sources and by the skillful use of double agents, the operation of the enemy intelligence services were effectively countered. In conclusion, it notes the consistent subservience of the Communist Party to the interests of the USSR and the likely threat to British security.

The renowned espionage historian offers “a gripping account of British intelligence during the last days of empire” (The Daily Telegraph). Drawing on a wealth of newly declassified records and hitherto overlooked personal papers, intelligence expert Calder Walton offers a compelling and authoritative history of Britain’s espionage activities after World War II. A major addition to intelligence literature, this is the first book to utilize records from the Foreign Office’s secret archive, which contains some of the darkest and most shameful secrets from the last days of Britain’s empire. Working clandestinely, MI5 operatives helped to prop up newly independent states across the globe against a ceaseless campaign of Communist subversion. Though the CIA is often assumed to be the principal actor against the Soviet Union through the Cold War, Britain plays a key role through its so-called “special relationship” with the United States. In Empire of Secrets, Walton sheds new light on everything from violent counterinsurgencies fought by British forces in the jungles of Malaya and Kenya, to urban warfare campaigns conducted in Palestine and the Arabian Peninsula. The stories here have chilling contemporary resonance, detailing the use and abuse of intelligence by governments that oversaw state-sanctioned terrorism, wartime rendition, and “enhanced” interrogation. “An important and highly original account of postwar British intelligence.” —The Wall Street Journal

Agent Zigzag: One December night in 1942, a Nazi parachutist landed in a Cambridgeshire field. His mission: to sabotage the British war effort. His name was Eddie Chapman, but he would shortly become MI5's Agent Zigzag. Dashing and louche, courageous and unpredictable, inside the traitor was a hero, inside the villain, a man of conscience: the problem for Chapman, his many lovers and his spymasters, was knowing where one ended and the other began. Ben Macintyre weaves together diaries, letters, photographs, memories and top-secret MI5 files to create the exhilarating account of Britain's most sensational double agent. Operation Mincemeat: One overcast April morning in 1943, a fisherman notices a corpse floating in the sea off the coast of Spain. When the body is brought ashore, he is identified as a British soldier, Major William Martin of the Royal Marines. A leather attaché case, secured to his belt, reveals an intelligence goldmine: top-secret documents Allied invasion plans. But Major William Martin never existed. The body is that of a dead Welsh tramp and every single document is fake. Operation Mincemeat is the incredible true story of the most extraordinary deception ever planned by Churchill's spies - an outrageous lie that travelled from a Whitehall basement, all the way to Hitler's desk. Double Cross: D-Day, 6 June 1944, the turning point of the Second World War, was a victory of arms. But it was also a triumph for a different kind of operation: one of deceit... At the heart of the deception was the 'Double Cross System', a team of double agents whose bravery, treachery, greed and inspiration succeeded in convincing the Nazis that Calais and Norway, not Normandy, were the targets of the 150,000-strong Allied invasion force. These were not conventional warriors, but their masterpiece of deceit saved thousands of lives. Their codenames were Bronx, Brutus, Treasure, Tricycle and Garbo. This is their story.
