The Cask of Amontillado by Edgar Allan Poe always freaks the students out a bit. If you want to freak them out even more, use this download that introduces the Catacombs of Paris.
10 questions, one after each paragraph of the Wikipedia article (linked and legal to use), followed by open source photos of the catacombs. Yes, you could easily create this on your own, but you don't want to spend another prep period or night at home creating this assignment when it's right here for you.
