Revealing the secret world of one of Britain's highest security jails as no one on the outside could possibly imagine, Norman Parker has spent over half his life in prison. He was released from prison after 23 continuous years in prison. From his arrival in Parkhurst in the early 1970s as a category-A prisoner, he mixed with some of Britain's hardest cases. Parkhurst is immensely tough. But Norman Parker has one special quality that helped sustain him there - he is a natural observer of the human condition. There at close quarters he encountered: gangsters, such as Reg and Ron Kray and Eddie Richardson; armed robbers, including Great Train Robber Buster Edwards; characters such as Billy G, a well-known London club owner who went robbing with John McVicar; and "Lambo" Rony Lambrianou of the Krays, as well as a host of others who would prove that Parkhurst itself was such a dangerous place that you had to watch out for your life.
