occasions when Johnson had thought the rain was falling straight up. Otherwise, how had the insides of his pants gotten wet? On Venus, everything came at you from all directions, it seemed to Johnson. Opening the door of the joint, it was noise instead of rain that came at him, the wild frantic beat of a Venusian rhumba, the perceptible emotional nuances of hate, love, fear, and rage. But mostly love. Since this place had been designed to excite the senses of both humans and Venusians, the love feelings were heavily tinged with straight sex. He sniffed at them, feeling them somewhere inside of him, aware of them but aware also that here was apprehension, and plain fear. "Is the mighty human wanting liquor, a woman or dreams?" His voice was all soft syllables of liquid sound. The Venusian equivalent of a headwaiter was bowing to him. tonight?" in a gesture indicating ecstasy. "It is my great regret that I must do just the right amount of it. "I'll have a tarmur to start but when does "Not just yet," Johnson said. "See me a little later." "But certainly." The headwaiter was gone into the throng. Johnson was at the bar. Behind it, a Venusian was bowing to him. "Tarmur," Johnson said. The green drink was set before him. He held it up to the light, admiring the slow rise of the tiny golden bubbles in it. To him, watching the bubbles rise was perhaps more important than drinking itself. "Beautiful, aren't they?" a soft voice said. He glanced to his right. A girl had slid into the stool beside him. She wore a green dress cut very low at the throat. Her skin had the pleasant tan recently on below the necklace ... Johnson felt his pulse quicken, for two reasons. Women such as this one had been quickening the pulse of men since the days of Adam. The second reason concerned her presence here in this place where no woman in her right mind ever came unescorted. Her eyes smiled up at him unafraid. Didn't she know there were men present here in this space port city who would snatch her bodily from the bar stool and carry her away for sleeping purposes? And Venusians were here who would cut her pretty throat for the sake of the necklace that circled it? are "I certainly do. Probably the rest of it is even nicer." "What the devil are you doing here on Venus and here in this place?" "Growing." The blue eyes were unafraid. Sombrely, Johnson regarded her. What was she doing here? Was she in the employ of the Venusians? If she was being planted on him, then his purpose here was suspected. He shrugged the thought aside. If his purpose here was suspected, there would be no point in planting a woman the motives of the killer. "You have decided them?" "Yes." "Every last one of them?" "Oh, there might be one or two matters undecided somewhere, say out on the periphery of the galaxy. But we will solve them when we get to bowing and scraping in front of him. "The great one has decided, yes?" "Say, I want to know more—" Johnson began. His words were drowned in were blended, but one aroma was prominent among them, the sweet, cloying, soul-stirring perfume of the Dreamer. In the suddenly hushed place little sounds began to appear as Venusians and humans began to shift their feet and their bodies in anticipation of what was to happen. "And you're the first woman who ever tried it on me." "But—" you than by using the Karmer grip." "What way?" Her eyes sparkled. "Eve's way," she answered. "Um!" Surprise sounded in his grunt. "But apples don't grow on Venus." "Eve's daughters don't use apples any more, darling. Come along." werewolves. Pillows and a thick rug covered the circling ramps. The soul-quickening Perfume of the Dreamer was stronger here. The throbbing of the lutes was louder. It was Venusian music the lutes were playing. Human ears found it inharmonious at first, but as they became "Yes." "What is it?" "How would I know?" "Johnny! How do you know my name?" "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. "But—" "And who besides Johnny Johnson would recognize the Karmer nerve grip "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 this room seemed to be paying no attention to him. His gaze came back to her. connection did she have with that frantic human genius he sought here? Johnson felt his skin crawl. He moved toward a nest of cushions on a ramp, found a Venusian was beating him to them, deftly changed to another nest, found it. Vee Vee flowed to the floor on his right, moved cushions to make him more comfortable. She moved in an easy sort of way left. thick and heavy. He sprawled to the floor on Johnson's left. Under Johnson had not seen Unger appear. One second the circle of light 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 drew closer to him. A few minutes earlier, she had been a very certain young woman, able was not prepared to disagree. Around him, he saw that the Venusians were already going ... going ... going.... Some of them were already gone. This was an old experience to them. They went rapidly. Humans went more slowly. The Venusian watchers had relaxed. They looked as if they were asleep, perhaps in a hypnotic trance, lulled into this state by the music and the perfume, and by something else. It was this something else that sent Johnson's thoughts pounding. The Venusians were like opium smokers. But he was not smoking opium. He was not in a hypnotic trance. He was wide awake and very much alert. He was ... the stars. He had made models of space ships. In a way, they had shaped his destiny, had made him what he was. They had brought him where he was this night, to the Dream Room of a Venusian tavern. The vision of the space ship floating in the void entranced and "See what?" Venusians were quiet. The music had shifted. A slow languorous beat of hidden drums filled the room. There was another sound present, a high-speed whirring. It was, somehow, a familiar sound, but Johnson had woman in love. He tried again for the space ship. It would not come. "This is it!" a voice whispered in his mind. "This is what you came to Venus to see. This ... this...." The first voice went into silence. Another voice took its place. "This is another damned vision!" the second voice said. "This ... can float upward toward the ceiling. Your damned eyes are tricking you!" "We are not tricking you!" the eyes hotly insisted. "It is happening. We are seeing it. We are reporting accurately to you. That Venusian can all die." "Die?" the chorus quavered. Venusian being jarred out of his dream. "Damn it!" A human voice said. A wave as sharp as the tip of a sword swept through the room. "Who did that?" "What happened?" Venusians were attacking a man. "It's Martin!" Caldwell shouted. "He is Struck by the gas-driven corvel charges, Venusians were falling. But there seemed to be an endless number of them. one."
