Stephan Talty has written a work of non-fiction dealing with the allied strategy of misinformation as it relates to the onset of D Day. The book reads like a novel as the author follows the life of Juan Pujol as he transformed himself into one of, or possibly the most important spy the allies developed during World War II. Even though the reader is fully aware of the outcome of wartime events, the author keeps you on the edge of your seat as operations are planned and executed. If you want a wonderful biography written in the context of the nether world of espionage during World War II, this book will be very satisfying.
