Into that darkness : from mercy killing to mass murder
Only four men commanded Nazi extermination (as opposed to concentration) camps.
Franz Stangl was one of them; he commanded Treblinka and was found guilty of co-responsibility for the slaughter there of at least 900,000 people.
Aiming to discover how human beings were turned into instruments of such overwhelming evil, Gitta Sereny investigates Stangl's mind, and the influences which shaped him.
Having talked to him for weeks and conducted months of research, she portrays the man as he saw himself and as he was seen by others, including his wife.
