<passage>:
Two men had died before Syme Rector's guns to give him the key to the ancient city of Kal-Jmar—a city of untold wealth, and of robots that made desires instant commands. [Transcriber's Note: This etext was produced from Getting through that dome had been his first urgent problem, but now he had another, and a more pressing one. It had been simple enough to pass himself off as an itinerant prospector and gain entrance to the city, after his ship had crashed in the Mare Cimmerium. But the rest would not be so simple. He had to acquire a spaceman's identity card, and he had to do it fast. It was only a matter of time until the Triplanet Before he could move to stop himself, he was over the edge. Too late, he realized what had happened—one of the hooks on the dead spaceman's harness had caught the heavy wristband of his chronometer. He was falling, linked to the body of his victim! Hardly knowing what he did, he lashed out wildly with his other arm, felt his fingertips catch and bite into the edge of the balustrade. His body hit the wall of the tower with a thump, and, a second later, the slipped free, and the tearing, unbearable weight vanished. The reaction swung Syme against the building again, and he almost lost his slippery hold on the balustrade. After a moment he heard the spaceman's body strike with a squashy thud, somewhere below. He swung up his other arm, got a better grip on the balustrade. He killed. He had heard no second thud, so the body must have stayed on the first outcropping of the tower it struck. It probably wouldn't be found until morning. inside him. "I wanta go to Kal-Jmar," said Tate. Syme snapped to attention, every nerve tingling. An indefinable sense, a hunch that had served him well before, told him that something big was coming—something that promised adventure and loot for Syme Rector. "Why?" he asked softly. "Why to Kal-Jmar?" Harold Tate told him, and later, when Syme had taken him to his rooms, he showed him what was in his little black suitcase. Syme had been right it was big. Kal-Jmar was the riddle of the Solar System. It was the only remaining city of the ancient Martian race—the race that, legends said, had risen to greater heights than any other Solar culture. The machines, preserved inside the city's bubble-like dome, after God knew how many thousands of years. But they couldn't be reached. For Kal-Jmar's dome was not the thing of steelite that protected Lillis: it was a tenuous, globular field of force that defied analysis as it defied explosives and diamond drills. The field extended both what had happened to the Martians, whether they were the ancestors of the present decadent Martian race, or a different species. No one knew anything about them or about Kal-Jmar. In the early days, when the conquest of Mars was just beginning, Earth scientists had been wild to get into the city. They had observed it had tried everything they knew to pierce the wall. Later, however, when every unsuccessful attempt had precipitated a bloody uprising of the present-day Martians—resulting in a rapid Thus matter had stood for over a hundred years, until Harold Tate. Tate, a physicist, had stumbled on a field that seemed to be identical in properties to the Kal-Jmar dome and what is more, he had found a force that would break it down. And so he had made his first trip to Mars, and within twenty-four hours, by the blindest of chances, blurted out his secret to Syme Rector, the scourge of the spaceways, the man with a thousand credits For Tate was no longer drunk, and it was important that it should not occur to him that he had been indiscreet. "So you think they might attack us?" Tate asked again, nervously. Tate peered through the steelite nose of the car. "Follow, I guess," Neither Syme nor Tate ever had a chance to test the efficiency of their blackness blot out part of the black sky directly overhead. He shouted, "Look out!" and grabbed for the nearest steering lever. The car wheeled around in a half circle and ran into the wall of the gully. Syme was saying, "What—?" when there was a thunderous crash that shook the sturdy walls of the car, as a huge boulder smashed into the ground immediately to their left. Syme was cursing slowly and steadily with a deep, seething anger. Tate Syme looked. "Those," he said bitterly, "are Martians." One Martian, who looked exactly like all the rest, stepped forward and on the outside of the helmet. " Kalis methra ," he began haltingly, "We had our reasons for not doing so," the Martian said. Tate looked interested. "But why this—this gigantic masquerade?" "You had nothing to give us," the Martian said simply. Tate frowned, then flushed. "You mean you avoided revealing yourselves because you—had nothing to gain from mental intercourse with us?" Tate thought again. "But—" "No," the Martian interrupted him, "revealing the extent of our The Martian looked at him appraisingly. "You already suspect. he could see no way out. He began to wonder, if he did, could he keep the Martians from knowing about it? Then he realized that the Martian "Will you tell us why?" Tate asked. Syme noticed that the other Martians had retired to the farther side of Tate squatted down comfortably on the floor of the cavern, apparently unconcerned, but his hands were trembling slightly. "First why—" he began. "There are many secrets in Kal-Jmar," the Martian said, "among them a very simple catalyzing agent which could within fifty years transform Mars to a planet with Terrestrially-thick atmosphere." Kal-Jmar Martians, I mean? I'd dearly love to know the answer to that one." "Neither of the alternatives in your mind is correct. They were not a "Several thousand years ago Mars' loss of atmosphere began to make itself felt. There were two ways out. Some chose to seal themselves into cities like Kal-Jmar our ancestors chose to adapt their bodies to "You see," he finished gently, "our deception has caused a natural "And yet," Tate mused, "you are being destroyed by contact with The Martian lowered his head. "That is for unborn generations." He It was like tangling with a draft horse. The Martian was astonishingly tear it out of the Martian's fingers. And all the time he could almost feel the Martian's telepathic call for help surging out. He heard the swift pad of his followers coming across the cavern. He put everything he had into one mighty, murderous effort. Every muscle fiber in his superbly trained body crackled and surged with power. He roared his fury. And the gun twisted out of the Martian's iron grip! weapon and snapped a shot at the nearest Martian. The creature dropped the rest in two terrible, lightning sweeps of his ray, then dropped the weapon from blistered fingers. He was gasping for breath, and realized that he was losing air from the seared-open right leg of his suit. He reached for the emergency it impartially over flesh and fabric. It felt like liquid hell on the burned, bleeding leg, but he kept on until the quick-drying fluid Only then did he turn, to see Tate flattened against the wall behind He led the way, wordlessly, back to the wrecked sand car. Tate followed didn't know what to do about it. Still silently, Syme refilled his oxygen tank, watched Tate do the
