The Dunwich Horror

"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 (pp. 481-508). It takes place in Dunwich, a fictional town in Massachusetts. It is considered one of the core stories of the Cthulhu Mythos.

Lovecraft took pride in "The Dunwich Horror", calling it "so fiendish that [Weird Tales editor] Farnsworth Wright may not dare to print it." Wright, however, snapped it up, sending Lovecraft a check for $240, equal to $2800 in modern dollars, the largest single payment for his fiction he had received up to that point.

Kingsley Amis praised "The Dunwich Horror" in New Maps of Hell, listing it as one of Lovecraft's tales that "achieve a memorable nastiness". Lovecraft biographer Lin Carter calls the story "an excellent tale... A mood of tension and gathering horror permeates the story, which culminates in a shattering climax". In his list of "The 13 Most Terrifying Horror Stories", T. E. D. Klein placed "The Dunwich Horror" at number four. Robert M. Price declares that "among the tales of H. P. Lovecraft, 'The Dunwich Horror' remains my favorite." S.T. Joshi, on the other hand, regarded "Dunwich" as "simply an aesthetic mistake on Lovecraft's part", citing its "stock good-versus-evil scenario". However, he has also noted that it is "richly atmospheric.

Although Lovecraft first mentioned "Yog-Sothoth" in the novel The Case of Charles Dexter Ward, it was in "The Dunwich Horror" that he introduced the entity as one of his extra-dimensional Outer Gods. It is also the tale in which the Necronomicon makes the most significant appearance, and the longest direct quote from it appears in the text. Many of the other standards of the Cthulhu Mythos, such as Miskatonic University, Arkham and Dunwich also form integral parts of the tale.

A librarian named Armitage appears in Don Webb's short story "To Mars and Providence", an alternate history where a juvenile Lovecraft is influenced by the events of H.G. Wells's The War of the Worlds.
