Sherlock Holmes and Dr. Watson investigate the legend of a spectral hound that haunts the Baskerville family on the desolate moors of Devon. Tasked with protecting the heir to the Baskerville estate, Sir Henry, from a potential supernatural threat, Holmes must apply his rigorous deductive logic to a case steeped in local folklore and atmospheric dread. The narrative unfolds primarily through the eyes of Dr. Watson, who serves as the boots-on-the-ground investigator while Holmes orchestrates the strategy from the shadows. The physical environment of Dartmoor acts as a primary antagonist, with its treacherous mires and fog-laden landscape complicating the search for a rational explanation behind the family curse.

Readers frequently highlight the effectiveness of the moor as a character in its own right, noting how the setting amplifies the sense of isolation and impending danger. Discussion often centers on the balance between the rational, clinical approach of Holmes and the encroaching supernatural atmosphere that threatens to overwhelm the investigation. Critics often point to the pacing of the novel as a model for the genre, as it maintains a steady build of suspense until the final confrontation. The interplay between the logical detective and his more grounded companion remains a central point of interest for those examining the evolution of the mystery genre. Many readers appreciate how the text manages to sustain a high level of tension without relying solely on action, instead prioritizing the slow unraveling of a complex, multi-layered mystery.
