"No," she whispered. "No, Hendley." He kissed her. When he opened the door and took her hand to help her step down, she said, "We should go separately." Surprised, he pondered the suggestion a moment. "I don't think we were noticed. And the museum is open all night. We can just go back—" "It would be safer," she insisted. "I—I'll meet you in front of the museum in five minutes. I can find my way out." He caught the appeal in her voice. And she might be right after all. If they were to use this meeting place again, it was just being sensible to come and go separately. "All right," he said. "You go first." Her hand gave his a convulsive squeeze. She dropped down into the tunnel, her steps ringing faintly on the metal staircase. He waited until the sounds had faded off. The sky was a deep blue now, and a single bright star was visible above the horizon. What must it be like to see the whole span of the sky lit up with stars? Now that he knew the way, he could come out and see. There was nothing to prevent him. There had never been anything but the habit of obedience.

The sound had been that of a door closing gently under its own power—or slowly eased shut. No more than the click of a latch, magnified along the tunnel. Now there was only silence. He didn't want to be caught here. No explanation would be accepted without an investigation—and there would be signs on the surface revealing that two people had been out together, a man and a woman. Slowly, setting each foot cautiously onto the metal steps, he began to descend. When he was low enough he leaned down and away from the staircase to peer along the tunnel. The service tunnel fed into a larger passage. There was a door at this opening, and another between the passage and the air conditioning-heating room. The door at the end of the tunnel was open. Perhaps Ann had left the farther door slightly ajar, and a slight current of air had caused it
