Britain’s most notorious twins - Ron and Reg Kray - ascended the underworld to become the most feared and legendary gangsters in London. Their escalating mayhem culminated in murder, for which they received life sentences in 1969.

While incarcerated, they received letters from a schoolboy from Tyneside, Steve Wraith, who was mesmerised by their story. Eventually, Steve visited them in prison and a friendship formed. The Twins hired Steve as an unofficial advisor, which brought him into contact with other members of their crime family. At Ron’s funeral, Steve was Charlie Kray’s right-hand man.

Steve documents Ron’s time in Broadmoor - a high-security psychiatric hospital - where he was battling insanity and heavily medicated. Steve details visiting Reg, who served almost 30 years in a variety of prisons, where the gangster was treated with the utmost respect by the staff and the inmates.
