Peter Hewitt was born in Windsor with the Great Depression looming. At age 18, following an MoD engineering apprenticeship, he was conscripted and served for eight years in the Fleet Air Arm. Upon release he entered Colonial Police Service, a career change that took him first to Kenya, followed by tours in Cyprus and Nyasaland. His police career concluded with a nine-year spell in the Royal Papua New Guinea Constabulary. Retuning to England in 1972 he took up an appointment with the Foreign and Commonwealth Office, where a succession of postings took him to diplomatic missions in Sierra Leone, East Berlin (GDR), Guyana and Lisbon-until a surfeit of `foreign parts' prompted him and his wife to settle in north London.
