Which detail from "the monkey paw" most clearly create tension?

Explanation:

On visiting the White family, Sergeant-Major Morris takes out the monkey's paw and tells them about the story he had been told. The summary of the story was that an old fakir had put a spell on it to demonstrate the fact that destiny controlled the lives of individuals. Also, that the spell conceded a total of three wishes. Listening to this story and the conditions Mr Morris seemed scared.
