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 his celebrated bestsellers, Macintyre told the dazzling true stories of a remarkable World War II double agent and of how the Allies employed a corpse to fool the Nazis and assure a decisive victory. He returns with the untold story of the grand final deception of the war and of the extraordinary spies who achieved it.
