Doyle, Arthur Conan - The Hound of the Baskervilles

This legend has been passing from age to age of Baskervilles family. Once upon a time two hundreds years ago or more at Baskerville Hall near bog was living Sir Hugo Baskerville. He was an aristocrat, alcoholic and rowdy. Once he was killed by a big black dog with shining eyes and mouth nearby of bogs. This dog punished his evil. Since than a lot of Baskervilles had passed away from dog's jaws. Two hundred years later Hugo's descendant named Sir Charles Baskerville has gone out in the evening for a walk in his park. Nobody saw him alive anymore. He died from the heart attack. Around his body were a lot of dog's tracks, but he never walked near bog's, because was afraid by the ghost of dog, he knew about Baskerville legend very well. Put a point in this deadly history would try Sherlock Holms.
