Holmes titled himself a "Consulting Detective". His powers of observation, his understanding of crime, and his insights into the criminal mind were brilliant. His knowledge of things not related to crime were extemely limited, except in opera and the violin.
Like many other authors famous for a single character, Arthur Conan Doyle attempted to "kill" Holmes. But the readers would not let this happen. Holmes eventually appeared in 56 short stories and 4 novels.
Many Holmes fans prefer Doyle's complete short stories, but their clockwork logic doesn't match the author's boast about this novel: it's "a real Creeper!" What distinguishes this particular Hound is its fulfillment of Doyle's great debt to Edgar Allan Poe--it's full of ancient woe, low moans, a Grimpen Mire that sucks ponies to Dostoyevskian deaths, and locals digging up Neolithic skulls without next-of-kins' consent. "The longer one stays here the more does the spirit of the moor sink into one's soul," Watson realizes. "Rank reeds and lush, slimy water-plants sent an odour of decay ... while a false step plunged us more than once thigh-deep into the dark, quivering mire, which shook for yards in soft undulations around our feet ... it was as if some malignant hand was tugging us down into those obscene depths."
