THREE AUTOGRAPH LETTERS, SIGNED (ALsS). Total of 4 1/2 pages, and an AUTOGRAPH NOTE SIGNED (ANs) on a post card, dated 2 January 1931 through 2 February 1931, the first to "Dear Madam" [Dorothy Sayers], the remainder to "Dear Miss Sayers, letters signed "Arthur Machen," post card initialed "A.M." Machen gives Sayers permission to include his short novel "The Great Return" in her anthology, GREAT SHORT STORIES OF DETECTION, MYSTERY AND HORROR, SECOND SERIES (Gollancz 1931). "I should be glad to let you use 'The Great Return' in your 'Great Short Stories' new collection ... [It] is a great favorite of mine, & has the advantage (from your point of view) of being little known to the general reader ... Isn't Ten Guineas a very small fee for 10,000 words? However --. If the publishers fail to produce a copy, I believe Mr. Fytton Armstrong ... has a few copies ... As to the American Edition: what happens? ..." A carbon of Sayers' reply to Machen's question (in his third letter dated 28 January 1931) about reprinting the story in an American edition is present. The post card acknowledges receipt of her reply: "Many thanks for letter: contents noted." Old mailing folds, pin holes in last letter, else fine. (#96346).
