On a dark night in 1944, OSS agent Craig Osbourne floated helplessly in the sea of the coast of Brittany. Hearing the rumble of engines, he thought he was finished when the wrong torpedo boat coasted out of the fog to pick him up – a German E-boat, the Lili Marlene. As the Kriegsmarine sailors pulled him over the rail and the Fregattenkapitan on the bridge turned to look down at him, Osbourne knew his war, and his life, were really over – until he found himself face-to-face with a man he had last seen at Harvard in 1939.
