INTERNATIONAL BESTSELLER The "compelling," untold story of the man who captured and brought to trial Rudolf H�ss--one of Nazi Germany's most notorious war criminals and subject of the Oscar-nominated film The Zone of Interest--"fascinates and shocks" (The Washington Post). May 1945. In the aftermath of the Second World War, the first British War Crimes Investigation Team is assembled to hunt down the senior Nazi officials responsible for the greatest atrocities the world has ever seen. One of the lead investigators is Lieutenant Hanns Alexander, a German Jew who is now serving in the British Army. Rudolf H�ss is his most elusive target. As Kommandant of Auschwitz, H�ss not only oversaw the murder of more than one million men, women, and children; he was the man who perfected Hitler's program of mass extermination. H�ss is on the run across a continent in ruins, the one man whose testimony can ensure justice at Nuremberg. Hanns and Rudolf reveals for the very first time the full, exhilarating account of H�ss's capture, an encounter with repercussions that echo to this day. Moving from the Middle Eastern campaigns of World War I to bohemian Berlin in the 1920s to the horror of the concentration camps and the trials in Belsen and Nuremberg, it tells the story of two German men--one Jewish, one Catholic--whose lives diverged, and intersected, in an astonishing way. This is "one of those true stories that illuminates a small justice in the aftermath of the Holocaust, an event so huge and heinous that there can be no ultimate justice" (New York Daily News).
