After dithering about like this in the cold for two or three minutes, Billy decided that he would walk on and take a look at The Bell and Dragon before making up his mind. He turned to go. And now a queer thing happened to him. He was in the act of stepping back and turning away from the window when all at once his eye was caught and held in the most peculiar manner by the small notice that was there. BED AND BREAKFAST, it said. BED AND BREAKFAST, BED AND BREAKFAST, BED AND BREAKFAST. Each word was like a large black eye staring at him through the glass, holding him, compelling him, forcing him to stay where he was and not to walk away from that house, and the next thing he knew, he was actually moving across from the window to the front door of the house, climbing the steps that led up to it, and reaching for the bell.
