The Hound of the Baskervilles is easier to adapt to the screen than most of Conan Doyle’s other stories and novels. It all seems there for a film maker to visualize: the surroundings, the atmosphere, the monster … It’s a hellova horror story. Most of his stories aren’t that filmic, they’re more introspective, relying on detective work rather than action. The ‘atmosphere’, the sense of being there with Holmes and Watson, is of course created by Conan Doyle’s magnificent style. Compare his writings to those of the avarage thriller writer. There are exceptions (notably Patricia Highsmith), but style is often as important to crime writers than to others. The best crime writers, had a great style: Raymond Chandler, Dashiell Hammet, Ross MacDonald, Dorothy Sayers, Conan Doyle, Sebastien Japrisot, John Le Carré.
