John Sutherland is a father of three who lives with his wife and children in south London. For more than twenty-five years he served as an officer in the Metropolitan Police, rising to the rank of Chief Superintendent before his retirement on medical grounds in 2018. John is a sought after public speaker and commentator on a broad range of issues, who regularly appears on TV and radio and writes for major newspapers. His first book, BLUE, written and published while he was still serving in the Met, was a Sunday Times bestseller. It tells the remarkable stories of his policing life and describes his long road to recovery following the serious nervous breakdown that ended his operational policing career.
