Well, there is definitely an interest in horror and fear; that is a common element in E.A.P.'s work. I think that there is also the juxtaposition of rationality and irrationality, and an exploration of the psychology of the narrator. Thinking about it, those are both also common elements in his work, as well. I think, not for sure, but I think a mysterious, decaying setting could also be an answer, but I'm not one hundred percent sure.
I hope this helps. Please let me know what the answers are; I'm a HUGE fan of Edgar, I'd love to know how well I helped. :)
