At the end of World War II, an estimated thirty thousand Nazi war criminals fled from justice. Many of them have names that resonate deeply in twentieth-century history -- Eichmann, Mengele, Martin Bormann, and Klaus Barbie -- not just for the monstrosity of their crimes, but also for the shadowy nature of their post-war existence. Guy Walters gives a comprehensive account of how the most notorious Nazi war criminals escaped justice; how they were pursued, captured, or able to remain free until their natural deaths; and how the Nazis were assisted while on the run by "helpers." Based on all-new interviews with Nazi hunters and former Nazi and intelligence agents, and travels along the actual escape routes, Hunting Evil authoritatively debunks much of what has previously been understood about Nazis and Nazi hunters in the post-war era, including the surprising truth about the world's most legendary Nazi hunter, Simon Wiesenthal.
