An elite Customs investigator, Michael Knox lived a clandestine and sometimes dangerous life of stakeouts, phone taps, intrigue and villainy. He's worked high-profile cases with a list of targets that would include the alleged chief of staff of the IRA, the man who became Britain's most famous entrepreneur, some of the first international drug traffickers and the importers of notorious porn film Deep Throat. The Investigator is the first ever biography of a senior Customs investigator and a revealing insight into a murky word where everyone's a suspect and few can be trusted.
