Someone in the Dark is a collection of fantasy and horror short stories by author August Derleth.

In Thirty Years of Arkham House, Derleth implied that this title had sold out by the end of 1944.

The additional 300 copies were printed in offset by Hunter Publishing Co. in Winston-Salem in 1965, the reprint probably authorized by Derleth himself.

[1] Someone in the Dark contains the following tales: E. F. Bleiler noted that "the local, regionalistic American stories are best, while those in imitation of Lovecraft are weakest".

[2] New York Times reviewer Louise Maunsell Field gave the collection a relatively favorable review, saying that "The stories are for the most part well told, and lovers of tales of the occult will find the volume entertaining and congenial, although it has little of either sensitivity or beauty.
