 Several of the stories relate to the Cthulhu Mythos and had appeared previously in the earliest collections "The Lurker at the Threshold", "The Survivor and Others", "The Shuttered Room and Other Pieces", "The Dark Brotherhood and Other Pieces" and other Arkham House publications.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letters to reviewers complaining that the stories were essentially Derleth's own works, incorporating fragments of unpublished Lovecraft prose.
