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

The detail from W. W .Jacobs’s "The Monkey’s Paw" that most clearly helps to create the tension is the time where Mr Morris seems scared to keep the monkey’s paw when Mr White asks him to.

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.
