These are the stories that you don't read in the papers or see on "Crimewatch" - and if they do appear they only skim the surface of what really happened. A senior detective and undercover agent in the Drug Squad and Regional Crime Squad - Britain's equivalent of the FBI - has broken ranks to reveal the stark truth behind the headlines. Duncan MacLaughlin, 40 years-old and a police officer all his life, is one of the elite. SAS-trained for special missions, his expertise is in surveillance and undercover work that could have got him killed at any moment. The dangerous tightrope he walked included cases involving master criminal Kenneth Noye, kidnap victim Julie Dart and the slaying of PC Keith Blakelock. He also penetrated international drug cartels and nailed the ruthless barons who control them.
The Filth is Duncan McLaughlin's first book. In addition to writing, MacLaughlin is a director of Saraigh Ltd, an investigation company he formed to undertake enquiries worldwide. He currently divides his time between homes in England and America. William Hall is a celebrated writer, broadcaster, film critic and show business journalist. His published works include biographies of celebrities such as James Dean, Norman Wisdom and Frankie Howard, as well as Raising Caine, the critically acclaimed biography of Michael Caine.
