What is the main idea of The Hound of the baskervilles?

Answer 1

The story starts when a man drops dead in the moors. A beggar tries to rob him. Holmes is told of an almost identical murder. They follow Mortimor and Henry Baskerville out so that nothing happens to him. Holmes and Watson find a man pointing a gun in a nearby cab and warn Henry. Watson and Henry later go out to the moors when they see a butler that looks like the gunman in the cab. He has a candle and is waving it about. Watson asks him of his actions. The butler disappears. They see a distant light that looks like a candle. They go out to the moors and find a lit candle in a stone cave. The beggar in the beginning of the story is spying on them.
