The much-reprinted “Fat Face” takes us into the seedy underworld of prostitutes and drug dealers in San Francisco, while other tales such as “Dagoniad,” “Copping Squid,” and “Tsathoggua” vividly meld Lovecraftian cosmic horror with the contemporary world of California, with its swimming pools and beachcombers. Shea was also fascinated with Lovecraft’s novel of Antarctic horror, At the Mountains of Madness, and his stories “Under the Shelf” and “Beneath the Beardmore” take us to that frozen land of death and terror.

The title story, “Demiurge,” is a previously unpublished novella that draws upon Lovecraft’s tales of psychic possession in its chilling portrayal of a nameless monster who may be the harbinger of the overthrow of the entire human race.

Michael Shea (1946–2014) was the award-winning author of The Color out of Time, the Nifft the Lean series of fantasy novels, and the classic tales “Polyphemus” and “The Autopsy.” This volume of his complete Cthulhu Mythos tales has been assembled by S. T. Joshi, a leading authority on Lovecraft and the Mythos.
