Key Figures in Espionage is a collection of brief biographies of legendary heroes, infamous traitors, and courageous operatives who fought with their brilliance, their cunning, and their determination to succeed.

Using information gleaned from historical documents, original US military and intelligence documents, individuals and official records throughout allied countries, as well as personal experience, Bayard & Holmes reveal the fascinating lives of espionage greats like Billy Waugh and Virginia Hall, notorious turncoats like Robert Hanssen and Kim Philby, and brilliant operatives who used what their mamas gave them, such as Josephine Baker and Amy Thorpe. With dry humor and a digestible narrative style, this compilation both illuminates and informs.
