How would you define the mood throughout the story "The Monkey's Paw"?

The type of mood that is established at the beginning of the story is dark and foreboding. this mood pretty much stays throughout the story, but fear and sadness are developed later when their son dies, and as his corpse is dragging itself up the road. There is also a sense of sadness as the father wishes the son away, using the final wish from the paw, and then burning it. Also, there is a sense of fear every time the gate creaks.
