The Hound of the Baskervilles brings Sherlock Holmes to his closest encounter with 
the supernatural. There are no vampires or ghosts, but a purported 
hound from hell measures out a good dose 
of horror. 
The novella is also one 
of Sir Arthur Conan Doyle's most Gothic tales, set along 
the mores 
of England and in an ancient mansion that borders them. What we have is Doyle at his best and his excellent character Sherlock Holmes--who is derived from Edgar Allan Poe's Dupin as I pointed out in 
Edgar Allan Poe Annotated and Illustrated Entire Stories and Poems--does not disappoint with his sleuthing prowess, either. If Poe had written one 
of Sir Arthur Conan Doyle's stories, this would have been it. A must read!
