It is the late 1930s, and a young Christopher bears witness to an unspeakable atrocity committed by a remorseless SS officer. When the action moves forward to the height of the Cold War, the SS man emerges out of the ruins of post-war Germany to destroy the last living witness to his crime. It's a case of tiger chasing tiger as Christopher is pursued by the only man who can match his craft or his instincts. With ferocious suspense and masterful pacing, Charles McCarry delivers a haunting parable of a man confronted with the ghosts of an entire generation's brutal history.
