On a warm summer night in July 1940, a sedan carrying agents of G2 military intelligence and the presidential secret service picked up a defector being held in the bachelor's officers quarters at Fort Myer Virginia. The prisoner was a German national named Ernst Hanfstaengl, known throughout his life as Putzi. Hanfstaengl was an agreeable fellow with considerable charm, well known through the salons of the Third Reich. Beyond his engaging personality, there was another reason for his popularity.
