Edmund Crispin is the pseudonym of Robert Bruce Montgomery, an English writer and composer best known for composing the soundtrack to the "Carry On" movies. Montgomery wrote his first novel, The Case of the Gilded Fly, on a bet—he bet a fellow Oxford student he could write better than John Dickson Carr, who was then all the rage. Under the Crispin pseudonym Montgomery wrote eight Gervase Fen novels and a collection of short stories between 1944 and 1953, and then stopped writing mysteries altogether, dedicating himself to composing and directing music. During this time he was also the London Sunday Times science fiction reviewer. Indeed, he was so successful at the latter that the Encyclopedia of Science Fiction claims "It would be difficult to exaggerate the importance of the early volumes [in the Best SF series] in establishing science fiction in the UK as a respectable branch of literature." In 1978 Gervase Fen reappeared in The Glimpses of the Moon; unfortunately, Montgomery died that same year.
