During his 28 years working as a prison officer, David Berridge has had to deal with it all: serial killers and gangsters, terrorists and sex offenders, psychopaths and addicts. Inside Parkhurst is his raw, uncompromising look at what really goes on behind the massive walls and menacing gates. Thrown in at the deep end, David quickly had to work out how to deal with the most cunning and volatile of prisoners, and learn how to avoid their many scams. He has been assaulted and abused; he has tackled cell fires and attempted suicides, riots and dirty protests; he has helped to foil escape plans, talked inmates down from rooftop protests, witnessed prisoners setting fire to themselves, and prevented prisoners from attempting to murder other prisoners. And now he takes us inside this secret world for the first time.
