Simon Beaufort is the pseudonym of Susanna Gregory and Beau Riffenburgh when they write jointly. Together they have written eight Geoffrey Mappestone novels and contributed to several Medieval Murderer books. In recent years, they have ventured into more modern times - the two Alec Lonsdale novels take place in Victorian London and The Nimrod Murders is set in Edwardian London, while The Murder House takes place in 21st century Bristol and The Killing Ship in the modern-day Antarctic.
