Double Cross: The True Story of the D-Day Spies by Ben Macintyre

4.0

It's title should perhaps be "The Amazing but True...". A fascinating and, yes, amazing history of the amateurish and haphazard espionage of WWII. Both sides really had no idea what they were doing; certainly the level of competence in this area had not progressed nearly as far as the technology and tactics of actual combat.
