The Hound of the Baskervilles
who are the suspects in chapter 7,8,9

The suspects are basically the same for much of the story:
Dr. Mortenson could be a suspect, but he only stood to gain a thousand pounds in the will. The Barrymores are rather secretive but their reasons come out later in the story. The prisoner running around the moor could be suspect simply because he is a prisoner.
