Magrs has also written licensed "Doctor Who" fiction without Wildthyme, including the 2007 novel, "Sick Building", (which made the shortlist for the Doncaster Book Award), a variety of audio plays for Big Finish and the BBC audio series, "Hornets' Nest", which marked the first time Tom Baker had returned to play the Doctor in a full-length drama since he left the role in 1981. After the success of Hornets' Nest, Magrs wrote two sequel series "Demon Quest" (2010) and "Serpent Crest" (2011).
