In this enthralling and eagerly anticipated (certainly by me) follow-up to his Baillie Gifford-winning East West Street, Sands investigates the truth behind what happened to one of the walk-on characters in that first book. As Nazi governor of Galicia, Otto von Wchter presided over a territory where hundreds of thousands of Jews and Poles were killed, including the entire family of Sands' grandfather. Indicted for mass murder when the war ended, Wchter went on the run, taking refuge in Rome, where he hoped to follow the "ratline" to Argentina, the destination of choice for Nazi fugitives. But in 1949, after lunching with an "old comrade" suspected of working for the Americans, he dies after a mysterious and violent illness. Was he poisoned? Sands investigates, weaving in the story of the enduring love between Wchter and his devoted wife; and exploring the Nazi legacy he left behind. Those who saw Sands' documentary "My Nazi Legacy" will know that his son Horst continues to deny that his father was responsible for mass murder. Here, alongside the brilliantly related story of what happened to Otto, Sands persists in his efforts to persuade Horst of the truth. Despite the gulf of horrors between them, he and Horst forge a friendship of sorts, and a degree of mutual understanding.
