Tenderness Of The Wolves - Tenderness Of The Wolves - Blu-ray

Fritz Haarmann, aka the Butcher of Hanover and the Vampire of Hanover, was a German serial killer responsible for the murders of two dozen boys and young men during the so-called 'years of crisis' between the wars. His case would partly inspire Fritz Lang's M, and it's central character portrayed by Peter Lorre, as well as this forgotten gem from 1973.
