Sir Arthur Conan Doyle 
The Hound of the Baskervilles 

What really killed Sir Charles Baskerville? Is his nephew, Sir Henry, in danger from the legendary family curse, a gigantic black hound? Sherlock Holmes and Dr. Watson are on the case in this classic mystery, set on lonely Dartmoor in Devonshire. Neolithic ruins, a perilous quagmire, eerie sounds in the night, and (of course) fog all add to the fun, with an escaped convict thrown in for good measure.
