The question asks whether the narrator of the story from 'The Stranger at Table Five' by T.A. Westacott is a reliable narrator or not. The reliability of a narrator in a first-person narrative depends on how much we can trust the voice telling the story. The degree of reliability can be determined by considering the narrator's perspective, biases, and mental state.
