Agent Zigzag: A True Story of Nazi Espionage, Love, and Betrayal by Ben Macintyre, 364 pages

Ben Macintyre is a very readable non-fiction writer.  He writes about the British Secret Service and the brilliant way they dominated Hitler's Third Reich during World War II.

Eddie Chapman was a thief who had the bad luck of being in jail on Jersey Island when it was occupied by the Germans at the beginning of World War II.  He was savvy enough to convince the Germans he would make a great spy for them.  Instead, as soon as he was returned to England, he let the British Secret Services know what he was up to so he could instead spy for them.

He may have been an unapologetic thief, but he was also a great spy for the Allies.  Known as Eddie to his friends, code named Fritz by the Germans and Zigzag by the British Secret Service, he was a man who loved adrenaline and turned that into a daringly successful run as a spy.
