According to his British passport, Douglas Renwick's occupation for many years was 'Government Service'. This included spells in Libya, Malta, Cyprus, Ireland and Germany. He also worked at the Ministry of Defence in London, the Supreme Headquarters of the Allied Powers in Europe in Belgium, the Pentagon in Washington DC, and White Sands Missile Range in New Mexico.
He has spent time in East Berlin, Mexico, Guatemala, Ecuador, Argentina, Egypt, Kenya, Namibia, South Africa, Burma, Cambodia, Laos and Vietnam. He has jumped out of planes, swum across Valetta harbour, skied across the Alps and the Rockies, and been transferred by breeches buoy from one Royal Navy ship to another, at sea and under full steam. He has been down a coal-mine in Yorkshire, a salt-mine in Poland and a nuclear bunker in Essex.
Now retired and living in Kent, time allows him to commit some of his experiences to paper. He prefers writing fiction on the grounds that it is safer.
