To get good insightful answers, how the question is framed matters. I missed an opportunity on Thursday
The unbelievable and true story of Juan Pujol, the double-agent known as Agent Garbo who played a key role in the successful deception operation that tied up Nazi forces at Pal de Calais during the Normandy Invasion and played a key role in the Western Allies victory against Nazi Germany.
I enjoyed this book greatly, it was a thrilling story of Garica, a man who seems unlikely to achieve anything, who wants to fight "for the good of humanity", tries to become a British spy and after being brushed aside by the Brits convinces the German's that he's a valuable spy, then finally becomes a British spy.
The book tells this story and then follows Agent Garbo as he deceptions of the Germans seem often on the verge of falling apart, his personal life and marriage are in difficulty, and finally to success.
Highly recommend, I own this book.
