Duncan MacLaughlin, 40 years old and a police officer all his life, is one of the elite. SAS-trained for special missions, his expertise was 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 drug cartels and nailed the ruthless barons who control them. Filled with black humour, exotic slang and facinating investigative detail that only an ex-copper could reveal, Duncan's story provides an rinsight into the world of major crime.
