A shocking account of Nazi genocide and the inhuman conditions in Auschwitz, but equally shocking is the initial disbelief with which the revelations were met.

Alfred Wetzler was a true hero. His escape from Auschwitz, and the report he helped compile, telling for the first time the truth about the camp as a place of mass murder, led directly to saving the lives of 120,000 Jews. No other single act in the Second World War saved so many Jews from the fate that Hitler and the SS had determined for them.Sir Martin Gilbert

Together with another young Slovak Jew Rudolf Vrba, both deported in 1942, the author succeeded in escaping from the notorious death camp in the spring of 1944. There were some very few successful escapes from Auschwitz during the war, but it was these two who smuggled out the damning evidence a ground plan of the camp, constructional details of the gas chambers and crematoriums and, most convincingly, a label from a canister of Cyclone gas.

The book is cast in the form of a novel to allow information not personally collected by the two fugitives but provided for them by a handful of reliable friends, to be included. Nothing, however, has been invented.

From the Introduction by Dr. Robert Rozett
Wetzler is a master at evoking the universe of Auschwitz, and especially, his and Vrba's harrowing flight to Slovakia. The day-by-day account of the tremendous difficulties the pair faced after the Nazis had called off their search of the camp and its surroundings is both riveting and heart wrenching. [...] Shining vibrantly through the pages of the memoir are the tenacity and valor of two young men, who sought to inform the world about the greatest outrage ever committed by humans against their fellow humans.
