Late at night, Sam took the office elevator down from the ninth floor. The display counted down: 8, 7, 6, 5, 4. Then it showed a floor he had never seen: 3½.
With a soft chime, the doors opened onto a dark hallway lined with his coworkers' desks. Every chair was turned to face him.
He jabbed the close button, and the doors began to slide shut. From the dark, a hand stopped them.
