Stephen is a retired police officer having served with Essex Police as a constable for thirty years between 1983 and 2013. He is married to Tanya and has two sons, Luke and Ross, and a daughter, Aimee. His sons served five tours of Afghanistan between 2008 and 2013 and both were injured. This led to the publication of his first book, Two Sons in a Warzone - Afghanistan: The True Story of a Father's Conflict, published in October 2010.

Both Stephen's grandfathers served in and survived the First World War, one with the Royal Irish Rifles, the other in the Mercantile Marine, whilst his father was a member of the Royal Army Ordnance Corps during the Second World War. When not writing Stephen can be found walking his three German Shepherd dogs with his wife Tanya, at some unearthly time of the morning, when most normal people are still fast asleep.
