D-Day, June 6, 1944. Some 150,000 Allied troops land successfully on the beaches of Normandy, sustaining only 5000 casualties. How did they manage it? Through a vast act of deception called Operation Bodyguard aimed at persuading the Germans that attacks would come at Calais and Norway, where German armies then massed. The spies drafted to perpetuate this trickery ranged from a Polish pilot to the wild daughter of a Peruvian diplomat to a Serbian playboy code-named Agent Tricycle. Actually, sounds like a great movie; meanwhile, best-selling author Macintyre (Operation Mincemeat) should turn in an absorbing read about a little-acknowledged facet of the war.

In Double Cross, New York Times bestselling author Ben Macintyre returns with the untold story of one of the greatest deceptions of World War II, and of the extraordinary spies who achieved it.

On June 6, 1944, 150,000 Allied troops landed on the beaches of Normandy and suffered an astonishingly low rate of casualties. D-Day was a stunning military accomplishment, but it was also a masterpiece of trickery. Operation Fortitude, which protected and enabled the invasion, and the Double Cross system, which specialized in turning German spies into double agents, deceived the Nazis into believing that the Allies would attack at Calais and Norway rather than Normandy. It was the most sophisticated and successful deception operation ever carried out, ensuring Allied victory at the most pivotal point in the war.

This epic event has never before been told from the perspective of the key individuals in the Double Cross system, until now. These include its director (a brilliant, urbane intelligence officer), a colorful assortment of MI5 handlers (as well as their counterparts in Nazi intelligence), and the five spies who formed Double Cross's nucleus: a dashing Serbian playboy, a Polish fighter-pilot, a bisexual Peruvian party girl, a deeply eccentric Spaniard, and a volatile Frenchwoman. The D-Day spies were, without question, one of the oddest military units ever assembled, and their success depended on the delicate, dubious relationship between spy and spymaster, both German and British. Their enterprise was saved from catastrophe by a shadowy sixth spy whose heroic sacrifice is revealed here for the first time.

With the same depth of research, eye for the absurd and masterful storytelling that have made Ben Macintyre an international bestseller, Double Cross is a captivating narrative of the spies who wove a web so intricate it ensnared Hitler's army and carried thousands of D-Day troops across the Channel in safety.
