Before that Agent Zigzag by Ben Macintyre. Telling the true story of Eddie Chapman, a dubious character who was recruited by Nazi Germany and parachuted into Britain. He immediately gave himself up and became a double agent. It reminded me of The Man Who Never Was written by Ewan Montagu who was a naval intel officer and came up with the idea about the Allied deception about the Sicily invasion. It was made into a film in 1956
Ben Macintyre's Operation mincemeat is an updated version of "the man that never was". It's a much more comprehensive and satisfactory account than Montagu's original book, in that Montagu wasn't able to explain how we knew that the Germans had taken the bait because the Ultra Secret was still just that.
Incidentally, Ewen Montagu was the officer who implemented the plan, but the idea was Ian Fleming's.
