TYPED LETTER SIGNED (TLS). 1 page, dated 15 March 1978, to "Dear Kirby" [McCauley], signed "Brian." On Lumley's pictorial letterhead with typed return address Roussillon Barracks, Chichester, W. Sussex. Lumley informs his literary agent, Kirby McCauley that he has finished his novel, IN THE MOONS OF BOREA, a sequel to CLOCK OF DREAMS and SPAWN OF THE WIND, and, in case Jove Books doesn't like it, he has written it in three easily-divided parts, so that it could be serialized. Plus, he's almost halfway through a short novel (which will include "Haggopian" as a chapter), here titled RETURN OF THE DEEP ONES, which he is writing for Arkham House at the suggestion of Jim Turner. Lumley, who started his career, like so many others, as a Lovecraft disciple, has been a prolific author of supernatural horror (of which his occult/Cold War Necroscope series is his best and best-known work), even while he was serving, as at this time, in the Royal Military Police. Kirby McCauley was probably the most important literary agent of horror, fantasy and sf writers in the boom years of the 1970s and 1980s. Faint creases where folded for mailing, a bit of creasing at the corners, near fine. (#102645).
