Cornwell and wife Judy co-wrote a series of novels published under the pseudonym "Susannah Kells": "A Crowning Mercy" published in 1983, "Fallen Angels" in 1984, and "Coat of Arms" (aka "The Aristocrats") in 1986. Cornwell's strict Protestant upbringing forms the background of "A Crowning Mercy", which takes place during the English Civil War. He also published "Redcoat" in 1987, an American Revolutionary War novel set in Philadelphia during its 1777 occupation by the British.
