Thom nodded, wiping a sleeve across his mouth. "Maybe. I wish we'd brought some water."

Raj grinned. "I wish you hadn't said that," he said. "I really do."

"Mirrors," Thom said. For the first time in Raj's memory, there was real awe in his friend's voice. "I've never seen mirrors like this.

"I've never seen a light like that, either," Raj said.

The room was circular, floored and roofed with mirrors, and with a single seamless sheet of mirror for the walls. The center of the circle was a pillar of light; white, glareless, heatless, odorless, shining on the endless repeated figures of the two men. Raj felt himself stagger in place, lost and splintered in fractions of himself. It was a moment before he noticed the last, the intolerable strangeness.

"Thom," he said urgently. "Why don't the mirrors reflect the light?" There it was before their eyes, a column as physically real as their own hands, a light that was all that kept this place from being as dark as a coffin. Yet in the mirrors there was no trace of it, only the two men and their equipment.

Thom blinked for an instant; then his eyes widened and he turned to run. Did run, one single step before freezing in place as if turned to stone. Even his expression froze, and Raj could see that his pupils shared the paralysis. The doorway that had been Thom's goal had. . not closed, simply vanished; only the direction of the living statue that had been his friend enabled Raj to tell it from any other part of the smooth mirror curve. The light-pillar in the center of the room blazed higher.

Raj fired, with his second finger on the trigger and the index pointing along the barrel, the way the armsman had taught him: at close range, you just pointed and pulled.
