In O’Connor’s story “A Good Man Is Hard to Find,” when she talks about suspense moving from the surface to the interior, I believe she means that the real suspense in the story comes from deeper ideas and feelings, not just the things that happen. Inside the story, it’s about how people are not always good, how they struggle with what is right and wrong, and how they can change. The story is not just about a family on a trip, but about their moral choices, like the grandmother being selfish, and their encounter with the Misfit, who challenges their beliefs. The suspense comes from their inner conflicts and the big questions about good and evil that they face. So, the story’s “interior” is all about these deep thoughts and feelings that make you wonder what will happen next and what it all means.
