The Filth

Duncan MacLaughlin, 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. 40 years-old and a police officer all his life, he 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.
