'When he met Sir Charles,he heard the story of the hell hound.He also learned that Sir Charles believed these super natural stories,and that he had a weak heart.
'Stapleton had the idea of buying a huge hound,and of using the phosphorus to make it shine like the hound in the story.I have found the place where he bought the animal.He took it by train to Devonshire and walked many miles over the moors with it so that it would not be seen near Baskerville Hall.
'He needed to get Sir Charles out of the Hall at night.This would be easy to do if his wife made Sir Charles fall in love with her.But,although he beat her,she refused to help him with his evil plan.
'Then Stapleton met Laura Lyons.We know that he made her write a letter to bring Sir Charles to the moor gate on that sad night.The hound,which was shining with phosphorus,chased Sir Charles down the Yew Alley.Sir Charles' terror was so great that his weak heart stopped,and he died,but the animal did not touch the dead body.
