The "Angel of Death" is what the prisoners of Auschwitz called Josef Mengele. Tens of thousands became victims of his "medical experiments", the description of which makes the blood run cold. After the war, they searched for him, but they could not find him. Who was he, this humble scion of a wealthy family, a medic of average abilities, who fearlessly accepted the inhuman ideas of Nazism? French writer Olivier Guez investigates one of the terrifying myths of the twentieth century in his stunning novel, resurrecting the fate of "Doctor Death" right up to the very end, when Mengele, persecuted by the whole world, changing names and countries, finds himself face to face with the ghosts of a terrible past.
