"Seventeen years after the fall of the Third Reich, Max Weill has never forgotten the atrocities he saw as a prisoner at Auschwitz--nor the face of Dr. Otto Schramm, a camp doctor who worked with Mengele on appalling experiments and who sent Maxs family to the gas chambers. As the war came to a close, Schramm was one of the many high-ranking former-Nazi officers who managed to escape Germany for new lives in South America, where leaders like Argentina's Juan Perón gave them safe harbor and new identities. With his life nearing its end, Max asks his nephew Aaron Wiley--an American CIA desk analyst--to complete the task Max never could: to track down Otto in Argentina, capture him, and bring him back to Germany to stand trial. Unable to deny Max, Aaron travels to Buenos Aires and discovers a city where Nazis thrive in plain sight, mingling with Argentine high society. He ingratiates himself with Ottos alluring but wounded daughter, whom hes convinced is hiding her father. Enlisting the help of a German newspaper reporter, an Israeli agent, and the obliging CIA station chief in Buenos Aires, he hunts for Otto--a complicated monster, unexpectedly human but still capable of murder if cornered. Unable to distinguish allies from enemies, Aaron will ultimately have to discover not only Otto, but the boundaries of his own personal morality, how far he is prepared to go to render justice"--.
