There is no ozzer one who has quite his touch at dreaming, mighty one." The headwaiter spread his hands in a gesture indicating ecstasy. "It is my great regret that I must do ze work tonight instead of being wiz ze dreamers. Ah, ze great Unger hisself!" The headwaiter kissed the tips of his fingers. "Um," Johnson said. "The great Unger!" His voice expressed surprise, just the right amount of it. "I'll have a tarmur to start but when does "In one zonar or maybe less. Shall I make ze reservations for ze mighty one?" As he was speaking, the headwaiter was deftly conducting Johnson to the bar. stool and carry her away for sleeping purposes? And Venusians were "They are "I am very knowing," the girl said, smiling. "Are you sufficiently knowing to be here?" For an instant, as if doubt crossed her mind, the smile flickered. Then Johnson choked as bubbles from the tarmur seemed to go suddenly up his nose. "My dear child ..." he sputtered. "I am not a child," she answered with a firm sureness that left no Vee Vee." "Vee Vee? Um. That is...." "I certainly do. Probably the rest of it is even nicer."

"You look as if you were considering some very grave matter," Vee Vee said. "Not any longer," he laughed. "Yes." "Every last one of them?" "Oh, there might be one or two matters undecided somewhere, say out on bowing and scraping in front of him. "The great one has decided, yes?" "The dreaming!" Vee Vee looked suddenly alert. "Of course. We must see moment. That there was danger in it, he did not doubt. But there might be something else. And "Oh. But very good. Ze great Unger, you will love him!" The headwaiter clutched the gold coins that Johnson extended, bowed himself out of sight. In the suddenly hushed place little sounds began to appear as Venusians and humans began to shift their feet and their bodies in anticipation "What a sweet, charming child you—" "I told you before, I'm not a child." interrupt." She was silent. A smile, struggling to appear on her face, seemed to "Um!" Surprise sounded in his grunt. "But apples don't grow on Venus." the room was in darkness, a fit hiding place for ghosts or Venusian throbbing of the lutes was louder. It was Venusian music the lutes were inside the human organism was touched by something, some force, some coldness now. Vee Vee's fingers left off patting his arm. "What is it?" "How would I know?" "Shouldn't I recognize one of Earth's foremost scientists, even if he is incognito on Venus?" Her voice had a teasing quality in it. "John Michael Johnson, known as Johnny to his friends, Earth's foremost expert in the field of electro-magnetic radiations within the human "Who are you?" His words were blasts of sound. "Please, darling, you are making a scene. I am sure this is the last thing you really want to do." He looked quickly around them. The Venusians and humans moving into Again she patted his arm. "Relax, darling. Your secrets are safe with me." A gray color came up inside his soul. "But—but—" His voice was suddenly weak. The fingers on his arm were very gentle. "No harm will come to you. Am I not with you?" "That's what I'm afraid of!" he snapped at her. If he had had a balance. Didn't she know that this was true? And as for Martin—But Caldwell had said that she had been asking about Martin. What connection did she have with that frantic human genius he sought here? a ramp, found a Venusian was beating him to them, deftly changed to operation but they knocked out a human or a Venusian in a matter of seconds. True, the person they knocked unconscious would be all right the next day. For this reason, many people did not regard the zit guns as had been empty, the next second the Venusian, smiling with all the impassivity of a bland Buddha, was in the light. He weighed three hundred pounds if he weighed an ounce, he was clad in a long robe that would impede movement. He had appeared in the bright beam of the spotlight as if by magic. Vee Vee's fingers dug deeper into Johnson's arm. "How—" "Shhh. Nobody knows." No human knew the answer to that trick. Unless perhaps Martin— Unger bowed. A little ripple of something that was not quite sound A few minutes earlier, she had been a very certain young woman, able to take care of herself, and handle anyone around her. Now she was had suddenly become a frightened child looking for protection. "Haven't you ever seen this before?" he whispered. Under the circle of light pouring down from the ceiling, the Dreamer lay motionless. Johnson found himself with the tendency to hold his breath. He was waiting, waiting, waiting—for what? The whole situation Around him, he saw that the Venusians were already going ... going ... to them. They went rapidly. Humans went more slowly. The Venusian watchers had relaxed. They looked as if they were asleep, that sent Johnson's thoughts pounding.

Beside him, Vee Vee was silent, her face ecstatic, like the face of a woman in love. and there with a multitude of tiny pinches, like invisible fleas biting him. Venus to see. This ... this...." The first voice went into silence. this is something that is not real, that is not possible! No Venusian We are seeing it. We are reporting accurately to you.

Do something." "Quiet!" Johnson ordered. if action is taken before the time for it—if that time ever comes—we can all die." "Die?" the chorus quavered. "Yes," Johnson said. "Now be quiet.

"I hear a whirring sound," his ears reported. "Please!" Johnson said. Venusian being jarred out of his dream. the voices. Although the language was Venusian, Johnson got most of the Venusians were attacking a man. Struck by the gas-driven corvel charges, Venusians were falling. But "Vee Vee!"
