Men kill each other for many reasons, but the two most common motives are greed and passion. Policemen and criminologists know that murders involving money and desire tend to be the most violent, for both impulses can drive the slayer to insane lengths. This book investigates nineteen of the most brutal murders ever committed by man. Readers will be shocked but fascinated by the black and sadistic trail of the Manson 'family' ; Lizzie Borden, whose story has passed into folk history ; Peter Kurten, the 'Vampire of Dusseldorf' and Leopold and Loeb, wealthy and well-born, who killed for amusement. Each story in this disturbing but compelling book is fully illustrated with black and white photographs sand diagrams.
