Stephen was born in Guernsey shortly before the outbreak of the Second World War and later illegally deported to concentration camps in Germany with his family. After these horrendous events, Stephen and his family returned to Guernsey where he was educated at Elizabeth College.
Stephen went on to join the Northern Rhodesia Police in 1959, with the express purpose of helping to Africanise the force prior to independence. His investigations took him over a great deal of the country, investigating horrendous and dangerous crimes, and securing more than 125 convictions for wildlife poaching.
The recipient of a plethora of awards and commendations, Stephen married Dr Xue Fen Matthews and now spends much of his time living in both France and China.
