When Ron and Reg Kray were sentenced to life imprisonment in 1968, most people thought that was the last they'd hear of two of the most notorious and vicious criminals Britain has ever produced. Instead, the twins and their evil doings have since achieved almost iconic status. Simultaneously, they have become 'Ronnie and Reggie', cuddly Robin Hood characters, little more than a couple of bad lads who loved their mum.

The Kray Files is an explosive investigative work which strips away the myths that have grown up around the brothers. It examines why the twins were put away, the true extent of their crimes and the truth about the last 30 years, which Ron and Reg spent at the expense of the country while making a quiet fortune through duplicitous dealings from behind bars. It looks at why their brother Charlie turned to drugs as his only way out of a life of deprivation and misery, and tries to discover the reason why some women have found the Krays fatally attractive.

For the first time ever, The Kray Files goes behind the scenes, painting a vivid picture of the brothers' world through psychological profiling, studying the sociology of the East End of London with the help of academics, and investigating the violent legacy the brothers have left behind.
