The corridor I was in began angling left and slanting downward and I thought that was wrong, but I kept on walking. All I could hear was the empty sound of my own footsteps and I didn’t pass a soul. Then I heard that sort of hollow roar ahead that means open space and people talking. The tunnel turned sharp left; I went down a short flight of stairs and came out on the third level at Grand Central Station. For just a moment I thought I was back on the second level, but I saw the room was smaller, there were fewer ticket windows and train gates, and the information booth in the centre was wood and old-looking. And the man in the booth wore a green eyeshade and long black sleeve protectors.
