On a sunny May morning in 1990, a bank courier strode out of the Bank of England and, minutes later, was robbed at knifepoint of 301 bearer bonds valued at £292 million. It was the biggest theft in British history. The thing is... when Keith Cheeseman received a call from a disbarred lawyer connected to London's underworld and attended a meeting on the night of the robbery, he counted £427 million in bonds - £135 million more than the Bank of England had reported. As Keith set out to launder the bonds, Scotland Yard and the FBI were always one step ahead in tracking them down. In this breathtaking adventure, featuring colourful characters from showbusiness alongside royalty, the IRA and even Pablo Escobar, Clifford Thurlow reveals Keith Cheeseman's incredible true story for the first time.
