What devices does Poe use to create and heighten the suspense in the story? Is the outcome ever in doubt?

In
","creates tension out of his use of dramatic . In the story's very beginning, his
narrator, Montresor, vows vengeance against Fortunato, giving the reader insight into his
motivations. Yet Fortunato himself remains ignorant of Montresor's designs, continuing to trust
in him even as he is brought deeper into his enemy's web.

I would suggest
that this tension is key in Poe's creation of suspense. With that being said, however, keep in
mind that Poe does not reveal everything to his readers right away. While Montresor's malice is
clearly expressed throughout text, the specific details concerning his vengeance are withheld
until the end. This only creates further tension in the story. We can assume Montresor plans to
exact some monstrous revenge against Fortunato, but we don't necessarily know what that revenge
entails.
