"The Dunwich Horror" is a horror short story by American writer H. P. Lovecraft. Written in 1928, it was first published in the April 1929 issue of Weird Tales. It takes place in Dunwich, a fictional town in Massachusetts. It is considered one of the core stories of the Cthulhu Mythos.
In the isolated, desolate, decrepit village of Dunwich, Massachusetts, Wilbur Whateley is the hideous son of Lavinia Whateley, a deformed and unstable albino mother, and an unknown father (alluded to in passing by mad Old Whateley, as "Yog-Sothoth"). Strange events surround his birth and precocious development. Wilbur matures at an abnormal rate, reaching manhood within a decade. Locals shun him and his family, and animals fear and despise him due to his odor. All the while, his sorcerer grandfather indoctrinates him into certain dark rituals and the study of witchcraft. Various locals grow suspicious after Old Whateley buys more and more cattle, yet the number of his herd never increases, and the cattle in his field become mysteriously afflicted with severe open wounds...
