Have you ever read stories of Sherlock Holmes—a famous detective? Here is one of his cases.
Stapleton, Charles' younger brother, found that he would inherit (继承) the Baskerville lands if Charles and his nephew(侄子) —Henry both died.
Charles who had a weak heart believed super natural stories. After knowing this, Stapleton had the idea of buying a huge hound, and of using the phosphorus(磷) to make it shine like the hound in one story.
Then Stapleton asked his friend Laura to write a letter to bring Charles to the moor gate on that sad night. The hound, which was shining with phosphorus, chased Charles down the Yew Alley. Charles' fear was so great that his weak heart stopped, and he died but the animal did not touch the dead body. There was no sign of murder. It was difficult for Holmes to find the murderer.
Two weeks later, Stapleton learned that Henry had reached England. He took his wife and the hound with him. He wore a false beard and followed Henry in London. He wanted to use the same way to murder Henry there. He needed something to give the hound Henry's smell, so he paid a woman at Henry's hotel to steal one of his shoes. The first one was a new one, which was no use for the hound, so it was put back. And then another older shoe was stolen. Before he was ready to murder Henry, he wasn't sure if his wife would keep his secret, so he did not tell her the truth. He locked her up in their hotel. She knew that he must have some evil plans. She sent Henry a letter which was made of words cut from a newspaper.
After receiving the letter, Henry realized he was in great danger and it must have something to do with his uncle Charles' death. So he asked Holmes for help.
