Some controversy exists among Lovecraft's admirers as to the ethics of presenting the stories as collaborative works. Upon this volume's publication, Donald Wandrei, one of Arkham House's founders, wrote letters to reviewers complaining that the stories were essentially Derleth's own works, incorporating fragments of unpublished Lovecraft prose. Gahan Wilson agreed that the stories "should really be billed as his [Derleth's] own, and merely based on the notes and letters of Lovecraft, and on the Lovecraftian mythos as he [Derleth] saw it, and no more than that."[1]
