Hardback. In the previous decade the world witnessed a frightening surge in mass murders and serial killings. This rash of multiple murders - in the sheer number of body counts and volume of blood spilled - shocked civilised society. Why this sudden proliferation of multiple murders, be they the bloody trail of carnage of serial murderer or the unexpected deadly explosion of a mass murderer? What makes someone go on a murderous rampage? How do serial killers and mass murderers differ? The authors have led the field in investigating these phenomena for over a decade. In this book they hold a magnifying glass to the minds of the perpetrators of these hideous crimes to explain the seemingly inexplicable. They produce profiles of the kinds of people who follow these murderous paths and examine the reasons behind their vicious acts. Featuring amongst others : Jeffrey Dahmer, Daniel Rolling, Joel Rifkin, Colin Ferguson, James Huberty etc. With Notes, References and Index. 267pp. 8vo. h/back. From the library of true-crime writer, Wilfred Gregg, with his personal b/plate. Nr. F. in Vg+ dw.
