"Then you aren't an ordinary human!" The instant he had blurted out the words, he was sorry he had spoken. It was possible to give away too much too soon.

"Then what am I?" Her voice was calm.

He dodged her question. "Aren't you even afraid to die?"

"When so many have died already, why should I hesitate to join them?" the nurse answered. She released his arm and brushed dust from the shoulders of her uniform. She glanced up at him and it seemed that some kind of a radiation flowed from her eyes, a wave of it that sent a tingle over his entire skin surface. Outside, another smaller boulder went bouncing past the entrance to the tunnel. Fumbling in his pockets for cigarettes, Zen found a crumpled package. He offered one to the nurse but she thanked him and refused it. He did not insist. Cigarettes were too precious to waste on people who didn't really want them. Outside, another man began to scream. The nurse moved automatically in that direction. He caught her arm and held her back.

"Wait until the rocks stop rolling, Nedra."

She did not protest. Looking up at him, she said, "You think I'm one of the new people, don't you?"

Zen coughed and swore at the cigarette, insisting that the tobacco was moist. This was a lie and both knew it. But—what to say? Her question was a complete stunner. "What makes you think that?" he asked, desperate for words.

"I just think it. It's true, isn't it?"

As an intelligence officer, Zen was accustomed to asking the questions, but this nurse had completely turned the tables on him. He took a deep drag on the cigarette. "I don't know. Are you?" He made his voice as casual as was possible.

Her eyes studied him. The trace of a smile came over her face and tugged at the comers of her lips. "Do you mind if I ask you a question?"
