This story of police corruption is based on six years of probing by three award-winning journalists, and offers evidence of the betrayal, by one of its own officers, of Scotland Yard's investigations into Britain's biggest-ever cocaine deal. The authors claim that gangster Roy Garner, a former meat porter who became a multi-millionaire, avoided imprisonment for 20 years - protected by Scotland Yard and ignored when he smuggled into the country cocaine valued at #100 million. The book alleges that his immunity from prosecution hinged on a partnership with Tony Lundy, a detective who was allowed to retire when the investigators closed in.
