Consider other stories from the horror genre, such as The Legend of Sleepy Hollow by Washington Irving or The Yellow Wallpaper by Charlotte Perkins. Many works by Edgar Allan Poe or HP Lovecraft would also be appropriate.
Consider another famous story from Ambrose Bierce, "An Occurrence at Owl Creek Bridge." To understand Bierce's style and wit outside of the horror genre, consider The Devil's Dictionary.
Consider stories that fit the genre in a less obvious way, such as Alice Sebold's "The Lovely Bones."
