Les Mason approached the huge gates of the prison with apprehension; he rapped on a highly polished brass knocker and a fierce man in uniform appeared and beckoned him in. Nothing could have prepared him for what he would see, what he would witness, what he would become a part of or the dramatic effect it would have on his young life. Prisons hold a profound fascination for people and the author grips the reader’s attention with a humorous but sometimes harrowing story inviting us into the unseen world of two of the most infamous prisons in Britain. ‘High Walls and Iron Bars’ is a true account of a Prison Officer’s long and dedicated career from the day of his recruitment until his eventual retirement.
