Thomas Carnacki is a fictional occult detective created by English fantasy writer William Hope Hodgson. Carnacki was the protagonist of a series of six short stories published between 1910 and 1912 in The Idler magazine and The New Magazine.
These stories were printed together as Carnacki, the Ghost-Finder in 1913. A 1947 Mycroft & Moran (an imprint of Arkham House) edition of Carnacki, the Ghost-Finder edited by August Derleth added three stories: "The Haunted Jarvee", published posthumously in The Premier Magazine in 1929; "The Hog", published in Weird Tales in 1947; and "The Find", a previously unpublished story.
