Bodyguard of Lies by Anthony Cave Brown

Bodyguard of Lies is the definitive account of the vast, secret war of deception that helped ensure the Allied victory in World War II. Anthony Cave Brown uncovers the extraordinary web of double agents, codebreakers, and master strategists who misled Hitler about the D-Day invasion — a campaign so intricate and audacious that its full scope was hidden for decades. Through meticulous research and gripping narrative, Brown reveals how intelligence, secrecy, and illusion became as decisive as firepower in defeating Nazi Germany. This monumental work remains one of the most compelling studies of espionage and deception in modern warfare.
