They stared, still breathing deeply from their race through the trees. The City was close, closer than they had ever seen it before. Never had they gotten so close to it in times past. Terrans were never allowed near the great Martian cities, the centers of Martian life. Even in ordinary times, when there was no threat of approaching war, the Martians shrewdly kept all Terrans away from their citadels, partly from fear, partly from a deep, innate sense of hostility toward the white-skinned visitors whose commercial ventures had earned them the respect, and the dislike, of the whole system. "How does it look to you?" Erick said. The City was huge, much larger than they had imagined from the drawings and models they had studied so carefully back in New York, in the War Ministry Office. Huge it was, huge and stark, black towers rising up against the sky, incredibly thin columns of ancient metal, columns that had stood wind and sun for centuries. Around the City was a wall of stone, red stone, immense bricks that had been lugged there and fitted into place by slaves of the early Martian dynasties, under the whiplash of the first great Kings of Mars. An ancient, sun-baked City, a City set in the middle of a wasted plain, beyond groves of dead trees, a City seldom seen by Terrans--but a City studied on maps and charts in every War Office on Terra. A City that contained, for all its ancient stone and archaic towers, the ruling group of all Mars, the Council of Senior Leiters, black-clad men who governed and ruled with an iron hand. The Senior Leiters, twelve fanatic and devoted men, black priests, but priests with flashing rods of fire, lie detectors, rocket ships, intra-space cannon, many more things the Terran Senate could only conjecture about. The Senior Leiters and their subordinate Province Leiters-- Erick and the two behind him suppressed a shudder. "We've got to be careful," Erick said again. "We'll be passing among them, soon. If they guess who we are, or what we're here for--" He snapped open the case he carried, glancing inside for a second. Then he closed it again, grasping the handle firmly. "Let's go," he said. He stood up slowly. "You two come up beside me. I want to make sure you look the way you should." * * * * * Mara and Jan stepped quickly ahead. Erick studied them critically as the three of them walked slowly down the slope, onto the plain, toward the towering black spires of the City. "Jan," Erick said. "Take hold of her hand! Remember, you're going to marry her; she's your bride. And Martian peasants think a lot of their brides." Jan was dressed in the short trousers and coat of the Martian farmer, a knotted rope tied around his waist, a hat on his head to keep off the sun. His skin was dark, colored by dye until it was almost bronze.
