"It is well to avoid actually recognized myths such as vampirism, reincarnation, etc., and invent one’s own obscure violations of cosmic law. What common myth, for example, does Blackwood use in The Willows? Or Chambers in "The Yellow Sign"? Or Hodgson in The House on the Borderland? These writers create a sort of distinctive awe of their own and manage to say something fresh despite all that has been said before."
