Agent Zigzag : the true wartime story of Eddie Chapman - lover, traitor, hero, spy

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 and louche, courageous and unpredictable, the traitor was a patriot inside, and the villain a hero.

The problem for Chapman, his many lovers and his spymasters was knowing who he was.

Ben Macintyre weaves together diaries, letters, photographs, memories and top-secret MI5 files to create the exhilarating account of Britain's most sensational double agent.
