"Carnacki, the Ghost Finder" by William Hope Hodgson is a collection of short stories published between 1910 and 1913. The work features Thomas Carnacki, an occult detective who investigates unusual hauntings using scientific methods, photography, and his fictional invention, the Electric Pentacle. Inspired by Sherlock Holmes, each story follows Carnacki as he recounts his latest case to close friends. The twist: some hauntings prove genuinely supernatural, while others are merely human fakery—keeping readers guessing throughout. (This is an automatically generated summary.)
