Whisperer in Darkness

The Whisperer in Darkness is a 26,000-word novella by American writer H. P. Lovecraft. Written February–September 1930, it was first published in Weird Tales, August 1931. Similar to The Colour Out of Space (1927), it is a blend of horror and science fiction. Although it makes numerous references to the Cthulhu Mythos, the story is not a central part of the mythos, but reflects a shift in Lovecraft''s writing at this time towards science fiction. The story also introduces the Mi-go, an extraterrestrial race of fungoid creatures. (Wikipedia)
