Bob Taylor retired as Detective Chief Superintendent of West Yorkshire Police with an unprecedented 100% clear-up record. In a career spanning 31 years, Taylor and his team were responsible for putting some of Britain's most evil criminals behind bars. That's why his officers called their guv'nor 'Crimebuster'. Taylor cut his teeth on the Yorkshire Ripper investigation. Then he tracked down some of the country's most notorious psychopaths and murderers, before becoming head of operations at the elite National Crime Squad, the UK's answer to the FBI. In this exclusive interview with Simon Ford, Bob Taylor talks about the Ripper enquiry, the shoe-fetish killer Christopher Farrow, the interrogation of psychopath Michael Sams, and the chilling case of the sadistic serial rapist, Clive Barwell.
