Now a TV series on AMC
 
Basing his tale on remarkable original research, historian Alexander Rose reveals the unforgettable story of the spy ring that helped America win the Revolutionary War. For the first time, Rose takes us beyond the battlefront and into the shadowy underworld of double agents and triple crosses, covert operations and code breaking, and unmasks the courageous, flawed individuals who inhabited this wilderness of mirrors—including the spymaster at the heart of it all, George Washington.
