In the 1940s, as the world was in the throws of World War II, strange and violent murderers, like Gordon Cummins, London's Blackout Ripper; John George Haigh, the acid-bath murderer and Ray Fernandez and Martha Beck, America's Lonely Hearts killers, took hold. Also included in this volume are accounts of Paul Ogorvov, who travelled Berlin's underground pushing innocent commuters onto the tracks, and 17-year-old William Heirans of Chicago who wrote on the wall above one of his victims For God's sake catch me before I kill more. This is part of Colin Wilson's True Crime File series: a history of 20th-century murder, by the author of The Mammoth Book of True Crime.
