We are stuck with Montresor for a guide through this story. As we have seen, he totally sucks. He only wants to show us icky morbid things. Like Fortunato, all we want is a little pleasure, and this tour is all about pain. We’ll be lucky to make it out alive. A guide like Montresor, a guy we mistrust from the beginning, forces us to think, to be on guard, to analyze everything Montresor tells us carefully. Which is what Poe claimed he wanted his stories to do: help us exercise our brains.
