"Medusa's Coil" is a short story by H. P. Lovecraft and Zealia Bishop. It was first published in Weird Tales magazine in January 1939, two years after Lovecraft's death. The story concerns the son of an American plantation owner who brings back from Paris a new wife. It mixes elements of Lovecraft's Cthulhu Mythos with the ancient Greek myth of Medusa, but it has also been noted for its racist aspects.
