The CONJURER of VENUS By CONAN T. TROY A world-famed Earth scientist had disappeared on Venus. When Johnson found him, he found too the secret to that globe-shaking mystery—the fabulous Room of The Dreaming. Johnson got rain in his eyes, his nose, and his ears. That was the way Johnson. Opening the door of the joint, it was noise instead of rain Feeling states came at him, intangible, but to his trained senses, 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. Caldwell, sitting in a booth next to the door, glanced up as Johnson that he had ever seen this human before. Nor did Johnson seem to "Is the mighty human wanting liquor, a woman or dreams?" His voice was all soft syllables of liquid sound. The Venusian equivalent of a "I'll have a tarmur to start," Johnson said. "How are the dreams tonight?" "Ze vill be the most wonserful of all sonight. The great Unger hisself one?" As he was speaking, the headwaiter was deftly conducting Johnson at the bar. Behind it, a Venusian was bowing to him. "Tarmur," Johnson 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 Johnson choked as bubbles from the tarmur seemed to go suddenly up his Sombrely, Johnson regarded her. What was she doing here? Was she in thick, his tongue heavy. Johnson's eyes went back to the girl but out "Um," Johnson said, his eyes on Vee Vee. "How—" merriment that danced in them there was ice. Johnson felt cold. the dreaming. Everyone wants to see the dreaming. We will go, won't we darling?" She hooked her hand into Johnson's elbow. "Certainly," Johnson said. The decision was made on the spur of the 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 Vee Vee, her hand on Johnson's elbow, rose. Johnson stood up with 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." Moving toward the open door that led to the Room of the Dreaming, Johnson saw that Caldwell had risen and was following them. Caldwell's signs. Johnson ignored them. With Vee Vee's fingers lightly patting his tingling feelings through his nose, Johnson entered the Room of the "Please!" Her voice grew sharp. "I think Johnny Johnson ought to know." "And who besides Johnny Johnson would recognize the Karmer nerve grip "And how would I make certain you were Johnny Johnson, except by seeing thing you really want to do." He looked quickly around them. The Venusians and humans moving into 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 Johnson felt his skin crawl. He moved toward a nest of cushions on thick and heavy. He sprawled to the floor on Johnson's left. Under effective weapons, but Johnson had a fondness for them. The feel of the Johnson felt his chest muscles contract, then relax. Vee Vee's fingers No human knew the answer to that trick. Unless perhaps Martin— dug at Johnson's arm as if they were trying to dig under his hide for lay motionless. Johnson found himself with the tendency to hold his sensed a pattern. Perhaps the path to the far-off stars passed this way, through such scented and musical and impossible places as these Rooms of the Dreamers. Certainly Martin thought so. And Johnson himself 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 ... watching a space ship float in an endless void . As Unger had come into the spotlight, so the space ship had come into his vision, out of nowhere, out of nothingness. The room, the Dreamer, the sound of the music, the sweetness of the perfume, Vee Vee and the universe. All he saw was the space ship. It was a wonderful thing, perhaps the most beautiful sight he had seen in his life. At the sight of it, a deep glow sprang inside of him. Back when he had been a kid he had dreamed of flight to the far-off 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 thrilled him. Something told him that this was real that here and now he was making contact with a vision that belonged to time. "Please, darling. You startled me. Don't move." Vee Vee's voice. Who was Vee Vee? The fingers dug into his arm. Pain came up in him. The space ship vanished. He looked with startled eyes at Vee Vee, at the Dream Room, at Unger, dreaming on the mat under the spot. "But, didn't you see it?" "See what?" "The space ship!" "No. No." She seemed startled and a little terrified and half asleep. "I ... I was watching something else. When you moved I broke contact with my dream." "Your dream?" He asked a question but she did not answer it. "Sit down, darling, and look at your damned space ship." Her voice was a taut whisper of sound in the darkened room. Johnson settled down. A glance to his left high-speed whirring. It was, somehow, a familiar sound, but Johnson had not heard it before in this place. He thought about the space ship he had seen. The vision would not come. He shook his head and tried again. Beside him, Vee Vee was silent, her face ecstatic, like the face of a woman in love. He tried again for the space ship. It would not come. Anger came up instead. So far as he could tell, he was the only one present who was not dreaming, who was not in a state of trance. His gaze went to Unger, the Dreamer.... An invisible force seemed to twitch at Johnson's skin, nipping it here "This is another damned vision!" the second voice said. "This ... this is something that is not real, that is not possible! No Venusian Dreamer, and no one else, can levitate, can defy the laws of gravity, We are seeing it. We are reporting accurately to you. That Venusian Buddha is levitating. We, your eyes, do not lie to you!" "You lied about the space ship!" the second voice said. "We did not lie about the space ship!" the eyes insisted. "When our master saw that ship we were out of focus, we were not reporting. Some other sense, some other organ, may have lied, but we did not." together." the voices. Although the language was Venusian, Johnson got most of the Johnson had no time to ask her what she meant. Somewhere in the back "It's Martin!" Caldwell shouted. "He "To hell with the woman!" Caldwell grunted. "Martin's the important Johnson followed.
