This is the first volume of Nigel West's acclaimed presentation of these fascinating diaries from the heart of Britain's Second World War intelligence operations. 'No intelligence buff can be without this volume and anyone interested in British twentieth century history needs it too.' M.R.D. Foot, The Spectator 'Regarded by historians as the most important military intelligence documents from the whole of the Second World War.' Irish Independent '[A] unique insight into the espionage secrets of the Second World War. Its historical importance is enhanced by the editing of Nigel West who, apart from decoding several obscure references to the secret war, persuaded the Security Service to break their rule of maintaining an agent's anonymity.' BBC History Magazine WALLFLOWERS is the codename given to one of the Security Service's most treasured possessions, the daily journal dictated from August 1939 to June 1945 by MI5's Director of Counter Espionage, Guy Liddell, to his secretary, Margo Huggins. The document was considered so highly classified that it was retained in the safe of successive Directors General, and special permission was required to read it. No other member of the Security Service is known to have maintained a diary and the twelve volumes of this journal represent a unique record of the events and personalities of the period, a veritable tour d'horizon of the entire subject. As Director, B Division, Liddell supervised all the major pre-war and wartime espionage investigations, maintained a watch on suspected pro-Nazis and laid the foundations of the famous 'double cross system' of enemy double agents. He was unquestionably one of the most reclusive and remarkable men of his generation, and a legend within his own organization.

The world was at war, America precariously poised on the sidelines. But already a second secret war was well underway with the United States very much in the thick of it. While he fought on the home front to consolidate the FBI's intelligence gathering power, J. Edgar Hoover was conducting an all-out campaign to make his agency America's first foreign espionage service--a campaign that would lead to an uneasy alliance with British intelligence in a brilliantly successful operation to undermine Germany throughout the Second World War. While pieces of the story have been told before, only now, in this work by FBI historian and former agent Raymond Batvinis, does this crucial chapter in the history of World War II, and of the FBI, received its full due. Taking up the tale begun in his acclaimed Origins of FBI Counterintelligence, Batvinis mines a wealth of heretofore untapped resources to expose Hoover's remarkable connivances and accomplishments in concert--and occasionally contention--with the Allies in outsmarting German intelligence. Hoover's Secret War opens up a world of spy rings, secret and double agents, surveillance, codes and ciphers, wire taps, microdots, mail drops, invisible ink, radio transmissions, and deception and disinformation as it tracks the warring nations spreading their intelligence tentacles throughout Europe and North and South America. As it documents the rocky evolution of the FBI's relationship with Britain's vaunted M15 and M16, the book brings to light the feud between Hoover and William Stephenson, director of the British Secret Intelligence Service's U. S. operation, BSC. Batvinis reveals how the agency gained access to ULTRA intelligence, thanks to the British decryption of the ENIGMA code, along with the strenuous efforts to keep the Germans in the dark about it. He uncovers eye-opening details of the FBI's participation in the famed "Double-Cross System, which effectively "turned" German agents against the Fatherland, among them a flamboyant, larger-larger-than-life playboy, a world famous French flyer, and a lecherous Dutchman. Batvinis tells for the first time how the Bureau manipulated these agents, and how it transmitted deceptive information critical to the Normandy landings, the Allied invasion of the Marshall Islands, and the atomic bomb program, among other matters. Rich with secrets and surprises worthy of the finest spy fiction, this true story of espionage and counterintelligence gives us our first clear look at the secret second world war, and a significant moment in history--for the FBI, for America, and for the world.

He was GARBO to the Allies and ALARIC to the Germans – the most successful double agent of the Second World War. Indeed, his spy network across Britain was so highly regarded that he was decorated for his achievements ... by both sides. Throughout the war, GARBO kept the Germans supplied with reports from his ring of twenty-four agents. Hitler's spymasters never discovered or even suspected a double-cross, but all the agents in GARBO's network existed solely in his imagination. In one of the most daring espionage coups of all time, GARBO persuaded the enemy to hold back troops that might otherwise have defeated the Normandy landings on D-Day; without him, the Second World War could have taken a completely different course. For decades, GARBO's true identity was a closely guarded secret. After the war, he vanished. Years later, after faking his own death, Juan Pujol García was persuaded by the author to emerge from the shadowy world of espionage, and in this new edition of his classic account, now updated to include his agents' original MI5 files, GARBO reveals his unique story.

Examines the United States- efforts to create and project a strong counterintelligence capability both at home and abroad during the 1930s. Several federal agencies, governmental departments, and military divisions vied for that role before it was eventually handed to the FBI. The author, a former FBI agent, chronicles the evolution, achievements, and failure of that effort.

Picking up where the million-copy bestselling Spycatcher left off, here is the first book to use newly declassified documents to expose the shocking double lives of the most notorious Soviet spies of the postwar era--the Cambridge spy ring.

“A compelling examination of an aspect of World War II that always has a rapt audience: espionage . . . With a cast of colorful characters.” —Library Journal (starred review) Beating the Nazi Invader is a revealing and disturbing exploration of the darker history of Nazis, spies and “Fifth Columnist” saboteurs in Britain, and the extensive top-secret countermeasures taken before and during the real threat of invasion in 1940. The author’s research describes the Nazi Party organization in Britain and reveals the existence of the Gestapo headquarters in central London. The reader gains vivid insights into Nazi agents and terrorist cells, the Special Branch and MI5 teams who hunted them and investigated murders believed to have been committed by Third Reich agents on British soil. Accessing a host of recently declassified files the book explores the highly classified measures taken for the protection of the Royal Family, national treasures and gold reserves. The British government made extensive plans for the continuation of government in the event of invasion including the creation of all-powerful Regional Commissioners, “Black Lists” of suspected collaborators and a British resistance organization. We also learn of the Nazis’ own occupation measures for suborning the population and the infamous Sonderfahndungsliste G.B, the Nazi “Special Wanted List.” The result is a fascinating insight into the measures and actions taken to ensure that Great Britain did not succumb to the gravest threat of enemy invasion and occupation for centuries. “Provides fresh and incisive answers to some intriguing 80-year-old mysteries about wartime espionage.” —Britain at War “A truly engrossing work.” —History of War Magazine
