The remarkable story of Josef Hartinger, the German prosecutor who risked everything to bring to justice the first killers of the Holocaust and whose efforts would play a key role in the Nuremberg tribunal. Before Germany was engulfed by Nazi dictatorship, it was a constitutional republic. And just before Dachau Concentration Camp became a site of Nazi genocide, it was a state detention center for political prisoners, subject to police authority and due process. The camp began its irrevocable transformation from one to the other following the execution of four Jewish detainees in the spring of 1933. Timothy W. Ryback's gripping and poignant historical narrative focuses on those first victims of the Holocaust and the investigation that followed, as Hartinger sought to expose these earliest cases of state-condoned atrocity.
