    Hearing Doctor Mortimer's narration, Holmes told the doctor to go to the station to meet Mr. Henry and come back the next morning. For the whole day that followed, Holmes kept thinking about the complicated and confusing case. After the analysis of the clues the doctor provided, he plotted that the dead saw a frightening monster while waiting for somebody in front of a little gate of his fence. He was so scared that he had to try to run away and he died of heart failure. But whom he was waiting for remained another mystery.
The next early morning, Doctor Mortimer brought the new owner of Baskerville. Henry had hardly arrived in London when he received a strange letter. It was pieced together with the words from newspapers. It said, "Stay away from the moors if you were reasonable and value your life." Who had learned of Henry's lodging place and sent this warning so quickly? Holmes did not find anything after a careful investigation.
