Jan and Mara looked at Erickson. "Go on," Jan said. "He knows who we are. Tell him the rest of the story."
"You might as well," Mara said.
Jan let out a sigh suddenly, a sigh of relief. "Let's put the cards on the table, get this weight off us. I'm tired of sneaking around, slipping—"
"Sure," Erickson said expansively. "Why not?" He settled back in his chair, unbuttoning his vest. "Certainly, Mr. Thacher. I'll be glad to spin you a story. And I'm sure it will be interesting enough to keep you awake."
They ran through the groves of dead trees, leaping across the sun-baked Martian soil, running silently together. They went up a little rise, across a narrow ridge. Suddenly Erick stopped, throwing himself down flat on the ground. The others did the same, pressing themselves against the soil, gasping for breath.
"Be silent," Erick muttered. He raised himself a little. "No noise. There'll be Leiters nearby, from now on. We don't dare take any chances."
Between the three people lying in the grove of dead trees and the City was a barren, level waste of desert, over a mile of blasted sand. No trees or bushes marred the smooth, parched surface. Only an occasional wind, a dry wind eddying and twisting, blew the sand up into little rills. A faint odor came to them, a bitter smell of heat and sand, carried by the wind.
Erick pointed. "Look. The City— There it is."
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.
"You look fine," Erick said to him. He glanced at Mara. Her black hair was tied in a knot, looped through a hollowed-out yuke bone. Her face was dark, too, dark and lined with colored ceremonial pigment, green and orange stripes across her cheeks. Earrings were strung through her ears. On her feet were tiny slippers of perruh hide, laced around her ankles, and she wore long translucent Martian trousers with a bright sash tied around her waist. Between her small breasts a chain of stone beads rested, good-luck charms for the coming marriage.
"All right," Erick said. He, himself, wore the flowing grey robe of a Martian priest, dirty robes that were supposed to remain on him all his life, to be buried around him when he died. "I think we'll get past the guards. There should be heavy morning traffic on the road."
They walked on, the hard sand crunching under their feet. Against the horizon they could see specks moving, other persons going toward the City, farmers and peasants and merchants, bringing their crops and goods to market.
"See the cart!" Mara exclaimed.
They were nearing a narrow road, two ruts worn into the sand. A Martian hufa was pulling the cart, its great sides wet with perspiration, its tongue hanging out. The cart was piled high with bales of cloth, rough country cloth, hand dipped. A bent farmer urged the hufa on.
"And there." She pointed, smiling.
A group of merchants riding small animals were moving along behind the cart, Martians in long robes, their faces hidden by sand masks. On each animal was a pack, carefully tied on with rope. And beyond the merchants, plodding dully along, were peasants and farmers in an endless procession, some riding carts or animals, but mostly on foot.
Mara and Jan and Erick joined the line of people, melting in behind the merchants. No one noticed them; no one looked up or gave any sign. The march continued as before. Neither Jan nor Mara said anything to each other. They walked a little behind Erick, who paced with a certain dignity, a certain bearing becoming his position.
Once he slowed down, pointing up at the sky. "Look," he murmured, in the Martian hill dialect. "See that?"
Two black dots circled lazily. Martian patrol craft, the military on the outlook for any sign of unusual activity. War was almost ready to break out with Terra. Any day, almost any moment.
"We'll be just in time," Erick said. "Tomorrow will be too late. The last ship will have left Mars."
"I hope nothing stops us," Mara said. "I want to get back home when we're through."
Half an hour passed. They neared the City, the wall growing as they walked, rising higher and higher until it seemed to blot out the sky itself. A vast wall, a wall of eternal stone that had felt the wind and sun for centuries. A group of Martian soldiers were standing at the entrance, the single passage-gate hewn into the rock, leading to the City. As each person went through the soldiers examined him, poking his garments, looking into his load.
Erick tensed. The line had slowed almost to a halt. "It'll be our turn, soon," he murmured. "Be prepared."
"Let's hope no Leiters come around," Jan said. "The soldiers aren't so bad."
Mara was staring up at the wall and the towers beyond. Under their feet the ground trembled, vibrating and shaking. She could see tongues of flame rising from the towers, from the deep underground factories and forges of the City. The air was thick and dense with particles of soot. Mara rubbed her mouth, coughing.
"Here they come," Erick said softly.
The merchants had been examined and allowed to pass through the dark gate, the entrance through the wall into the City. They and their silent animals had already disappeared inside. The leader of the group of soldiers was beckoning impatiently to Erick, waving him on.
