David Berridge joined the prison service in 1992, three weeks short of his 32nd birthday. He started his training at HMP Shrewsbury and then spent the next 22 years on the Parkhurst landings, dealing with the country's most violent and badly-behaved prisoners. During his time there he worked amongst Category A inmates, including serial killers, terrorists and armed robbers, in a dispersal unit, mentally ill inmates in a high security psychiatric unit, and high-risk inmates in a protected witness unit. Eight years ago he moved to HMP Albany.

David retired from the prison service in 2019 at the age of sixty. His first book, Inside Parkhurst, was an instant Sunday Times bestseller and helped to raise awareness for the ongoing problems within our prison service. This follow-up intends to build on this success. David will support and promote in full on publication.
