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 & louche, courageous & unpredictable, the traitor was a patriot inside, & the villain a hero. The problem for Chapman, his many lovers & his spymasters was knowing who he was. Ben Macintyre weaves together diaries, letters, photographs, memories & top-secret MI5 files to create the exhilarating account of Britain`s most sensational double agent.
