A sequel to the "Encyclopaedia of Murder", this is an account of the most famous murderers and murder cases since 1962, more than two decades which have seen a frightening increase in apparently motiveless murders. The authors are supplying new entries and some revisions to bring it up-to-date. Colin Wilson is author of some 50 books, many of which are studies of criminology and sexuality past and present. His best known are "Outsider Cycle", "Originals of the Sexual Impulse" and "A Case-book of Murder". Donald Seaman was on the staff of the "Daily Express" for 25 years working variously as a crime reporter, feature-writer and foreign correspondent. He has written six thrillers and one expose of the intelligence network "The Great Spy Scandal".
