L'Île Noire
Title of a French aristocrat and the fictional author of "Cultes des Goules", inspired by the ancestral form of Mythos author August Derleth's name. The fictional writer is first mentioned in Robert Bloch's 1935 story "The Suicide in the Study", which calls his book "ghastly". Lovecraft uses the name in two 1935 stories, "The Shadow Out of Time" and "Haunter of the Dark", the latter of which calls d'Erlette's work "infamous". Derleth himself refers to d'Erlette in “The Adventure of the Six Silver Spiders” (1950) and “The Black Island” (1952).
