A NAZI WAR CRIMINAL WHO IS SUPPOSED TO BE DEAD  When Schramm escaped to South America after the war, Max swore to one day bring him back to Germany to stand trial. With his life now nearing its end, he asks his nephew Aaron Wiley - a CIA desk analyst - to capture the doctor.

PRAISE FOR JOSEPH KANON:  ​ 'Joseph Kanon owns this corner of the literary landscape and it's a joy to see him reassert his title with such emphatic authority' Lee Child 'Clever, devious and morally complex' Sunday Times 'Sensational!

Kanon writes beautifully, superbly . . . he is the master of the shadows of the era' The Times 'The critical stock of Joseph Kanon is high, and Defectors will add further lustre to his reputation . . .
