Thomas Carnacki may well be considered one of the first true occult detectives, as he combined both knowledge and experience of what he calls “the ab-natural” with scientific deductive method and equipment. The adventures of Carnacki have been continued by a number of writers, including A. F. Kidd in collaboration with Rick Kennett in "472 Cheyne Walk: Carnacki, the Untold Stories" (2000), William Meikle in "Carnacki: Heaven and Hell" (Colusa, CA: Ghost House Press, 2011), Brandon Barrows in "The Castle-Town Tragedy" (Dunhams Manor, 2016), and others. In addition, writers Joshua M Reynolds and John Linwood Grant have each produced a separate series of stories which follow on from Carnacki's death, and feature occult detectives whose work relates to the original tales - "The Adventures of the Royal Occultist" and "Tales of the Last Edwardian" respectively.
