Gotch struck off through the darkness with Crag at his heels. The stars shone with icy brilliance. Overhead Antares stared down from its lair in Scorpio, blinking with fearful venom. The smell of sage filled the air, and some sweet elusive odor Crag couldn't identify. A warmth stole upward as the furnace of the desert gave up its stored heat. He strained his eyes into the darkness; stars, the black desert ... and the hulking form of Gotch, moving with certain steps. He saw the rocket with startling suddenness--a great black silhouette blotting out a segment of the stars. It stood gigantic, towering, graceful, a taper-nosed monster crouched to spring, its finned haunches squatted against the launch pad. They were stopped, challenged, allowed to proceed. Crag pondered the reason for their visit to the drone. Gotch, he knew, had a good reason for every move he made. They drew nearer and he saw that most of the catwalks, guardrails and metal supports had been removed--a certain sign that the giant before them was near its zero hour. Another sentry gave challenge at the base of the behemoth. Crag whistled to himself. This one wore the silver leaf of a lieutenant colonel! The ritual of identification was exacting before the sentry moved aside. A ladder zigzagged upward through what skeletal framework still remained. Crag lifted his eyes. It terminated high up, near the nose. This was the Aztec! The real Aztec! The truth came in a rush. The huge silver ship at Burning Sands, which bore the name Aztec, was merely a fake, a subterfuge, a pawn in the complex game of agents and counter-agents. He knew he was right. "After you," Gotch said. He indicated the ladder and stepped aside. Crag started up. He paused at the third platform. The floor of the desert was a sea of darkness. Off in the distance the lights of Alpine Base gleamed, stark against the night. Gotch reached his level and laid a restraining hand on his arm. Crag turned and waited. The Colonel's massive form was a black shadow interposed between him and the lights of Alpine Base. "This is the Aztec," he said simply. "So I guessed. And the silver job at Burning Sands?" "Drone Able," Gotch explained. "The deception was necessary--a part of the cat and mouse game we've been playing the last couple of decades. We couldn't take a single chance." Crag remained silent. The Colonel turned toward the lights of the Base. He had become quiet, reflective. When he spoke, his voice was soft, almost like a man talking to himself. "Out there are hundreds of men who have given a large part of their lives to the dream of space flight. Now we are at the eve of making that dream live. If we gain the moon, we gain the planets. That's the destiny of Man. The Aztec is the first step." He turned back and faced Crag.
