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 occasions when Johnson had thought the rain was falling straight up. Otherwise, how had the insides of his pants gotten wet? Johnson. Opening the door of the joint, it was noise instead of rain notes pounding and jumping through the smoke and perfume clouded room. 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 that he had ever seen this human before. Nor did Johnson seem to "I'll have a tarmur to start," Johnson said. "How are the dreams 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. the dreaming commence?" one?" As he was speaking, the headwaiter was deftly conducting Johnson below the necklace ... Johnson felt his pulse quicken, for two reasons. 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 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 periphery of the galaxy. But we will solve them when we get to them." He waved vaguely toward the roof and the sky of space hidden merriment that danced in them there was ice. Johnson felt cold. "The dreaming!" Vee Vee looked suddenly alert. "Of course. We must see clutched the gold coins that Johnson extended, bowed himself out of sight. "Say, I want to know more—" Johnson began. His words were drowned in a blast of trumpets. The band that had been playing went into sudden 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 The soul-quickening Perfume of the Dreamer was stronger here. The playing. Human ears found it inharmonious at first, but as they became accustomed to it, they began to detect rhythms and melodies that human minds had not known existed. The room was pleasantly cool but it had the feel of dampness. A world that was rarely without pelting rain would have the feel of dampness in its dreaming rooms. tingling feelings through his nose, Johnson entered the Room of the Dreamer. He suspected that other forces, unknown to him, were catching hold of his senses. He had been in dreaming rooms many times before but "What is it?" "How would I know?" "Please!" Her voice grew sharp. "I think Johnny Johnson ought to 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. "But—" "And how would I make certain you were Johnny Johnson, except by seeing me." A gray color came up inside his soul. "But—but—" His voice was suddenly weak. 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? 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 the man's coat, Johnson caught a glimpse of a slight bulge, the zit 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 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 "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 passed through the audience. Unger bowed again. He stretched himself flat on the mat, adjusted the rest to support his head, and apparently went to sleep. Johnson saw the Dreamer's eyes close, watched the chest 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 breath. He was waiting, waiting, waiting—for what? The whole situation was senseless, silly, but under its apparent lack of coherence, he Rooms of the Dreamers. Certainly Martin thought so. And Johnson himself perhaps in a hypnotic trance, lulled into this state by the music 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. his vision, out of nowhere, out of nothingness. The room, the Dreamer, knew they did exist, the memory of them, and of other things, was out on the periphery of his universe, perhaps of the universe. All he saw was the space ship. It was a wonderful thing, perhaps the most beautiful sight he had seen 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 "Your dream?" 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 He thought about the space ship he had seen. The vision would not come. He shook his head and tried again. He tried again for the space ship. It would not come. Anger came up instead. Somehow he had the impression that the whirring sound which kept intruding into his consciousness was stopping the vision. So far as he could tell, he was the only one present who was not dreaming, who was not in a state of trance. An invisible force seemed to twitch at Johnson's skin, nipping it here "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." "I—" Johnson whispered. him what they were doing. These were voices out of his training days when he had learned the names of these functions and how to use them. "Be quiet!" he said roughly. The little voices seemed to blend into a single chorus. "Action, Master! Do something." "Quiet!" Johnson ordered. "But hurry. We are excited." "I hear a whirring sound," his ears reported. "Please!" Johnson said. In the front of the room Unger floated ten feet above the floor. "Master, we are not lying!" his eyes repeated. "I sweat...." his skin began. "Watch Unger!" Johnson said. The Dreamer floated. If wires suspended him, Johnson could not see them. If any known force lifted him, Johnson could not detect that There was a split second of startled silence in the Dreaming Room. The the voices. Although the language was Venusian, Johnson got most of the meaning. His hand dived under his coat for the gun holstered there. At his left, Caldwell was muttering thickly. "What—what happened? I was back in the lab on Earth—" Caldwell's voice held a plaintive note, as if some pleasant dream had been interrupted. hungrily against his lips, pressed very hard, then gently drew away. "What—" he gasped. "I had to do it now, darling," she answered. "There may not be a later." Johnson had no time to ask her what she meant. Somewhere in the back
