Dr. Aribert Heim worked at the Mauthausen concentration camp for only a few months in 1941 but left a horrifying mark on the memories of survivors. According to their testimony, Heim euthanized patients with injections of gasoline into their hearts. He performed surgeries on otherwise healthy people. Some recalled prisoners" skulls set out on his desk to display perfect sets of teeth. In the chaos of the postwar period, Heim was able to slip away from his dark past and establish himself as a reputable doctor in the resort town of Baden-Baden. He was tall, handsome, a bit of a charmer, and quickly settled down with a wife and children in peace and comfort. But certain rare individuals in Germany were unwilling to let Nazi war criminals go unpunished. Among them was a police investigator named Alfred Aedtner, who turned finding Heim into an overriding obsession; his quest took him across Europe and across decades, and into a close alliance with legendary Nazi hunter Simon Wiesenthal. This is the incredible story of how Aribert Heim evaded capture, living in a working-class neighborhood of Cairo, praying in Arabic, beloved by an adopted Muslim family, while inspiring a manhunt that outlived him by many years. He became the ETERNAL NAZI a symbol of Germany"s evolving attitude toward the sins of its past, which finally crested in a desire to see justice done at almost any cost.
