"Much the same concept, though. This is just vastly more sophisticated—and more effective. It doesn't mirror what's actually happening on the stage. It reflects the audience's reaction to it. I don't pretend to know how it's done, but the screen—or the computer complex directing it—records the impulses of all our thought waves, selects and synthesizes them. What comes out, though it's often a montage, is not one viewer's reaction, but the total reaction. Ah! You see? Those two dancers on the left—see them down on the stage? Now look at the screen!"

Hendley saw. The tempo of the dance had quickened, the pantomime of the dancers had become more daring. But the stage performance remained essentially suggestive. The version of it which appeared on the thought-screen was a blunt and strangely hideous extension of that suggestion into the realm of the obscene.

Hendley tore his gaze away from the screen.

"Unbelievable, huh?" Nik murmured. "I've sometimes wondered if it might all be a hoax." When Hendley glanced at him sharply the young Freeman shrugged. With an urbane smile he said, "Why not? Whatever it is, it's a remarkable machine. But it could simply be showing what a very clever computer says the audience reaction would be. That would be much the same as showing the actual thoughts, wouldn't it? Who could tell the difference?"

Hendley closed his eyes. Any pleasure he might have found in the spectacle had long since vanished. But he could not shut his ears to the sensual rhythms of the music or erase the lurid images which danced in the darkness behind his eyelids. In the end he had to open his eyes—to seek out the willowy girl stained with crimson light, to torture himself with a glimpse of lips parted in a smile, a fleeting motion of long slim legs nimbly scissoring, a bobbing nest of short soft curls, now dyed from gold to red. He knew now why Ann had been evasive, and why she had run away. He had many answers now. What he did not know—and what continued to torment him—was whether or not everything that had happened between them, every sigh, every caress, had been no more than the dance on the stage—a pantomime of passion.

In the middle of a chord the music crashed to a stop. The dancers were motionless, frozen in various attitudes of pursuit and withdrawal, like figures on an urn. The audience, after an initial stir of talk and restless movement, became hushed, waiting. Slowly the woman in blue looked over her entourage. Her light-whip rose, whirled above her head, and struck across the stage. A kneeling figure, stung by the lash, obediently stood and walked to the center of the stage. She was the first girl who had appeared—her white tag bore the number 1. Around her the lights dimmed until there was only a single spotlight, fixing her in its bright red gaze. In the cylindrical materializer her beauty was imprisoned with startling realism. Her eyes and her lips smiled. Her head bent in sweet resignation.

Many times larger than life, the girl's image appeared on the giant screen directly over the stage. Above her head on the screen a number suddenly blazed in red light: Z11-3460. It blinked off, then on again. A woman's soft, caressing voice purred the number over the speaker system. From somewhere on the main floor came an excited shout. There were a few cheers, a sprinkling of laughter. But through most of the audience there rippled a sigh, as of held breath slowly released.

The lights went out briefly. When the spotlights stabbed on again, the girl in the center of the stage was gone. The dance took up as if it had never been interrupted. Hendley sank back onto his seat, unaware until then that he had half-risen. He felt limp, exhausted. And he could hear—he could feel—a change in the audience. It was quieter, abnormally still, betraying tense expectancy in the remark unmade, the weight unshifted, the glass untouched.

Hendley shook his head as if to break the spell. Deliberately he raised his own glass and drank. He knew he shouldn't. The dizziness had begun to return. He was passing the point of control. Watching the gyrations of the dance, the erotic version of it appearing in monstrous detail on the thought-screen, made his eyes ache, his head whirl. Knowing that Ann was a part of it brought a sting of anguish....

Crash! The music died, the movement on stage was arrested once more. Lights dimmed and a second girl took her place at stage center, a tall girl whose shapely contours were carved in provocative red shadows. Another ticket number stabbed its crimson message onto the screen above the stage. Another delighted yelp was heard, another general sigh.
