"Let's go down and meet this Bennett Keifer," Alan said. And, to Laura: "Don't worry about anything, Laura. It's going to be all right."

But when he reached for her hand, she withdrew it and would not meet his eyes directly.


There was nothing but the ochre wastelands of Mars, the dunes marching, windswept, from horizon to horizon. Far away to the east, a thin green line knifed across the rusty sands where vegetation clung precariously to the banks of a Martian canal, nurtured by the waters it brought down from the melting polar cap.

The militiamen flanked them on either side as they walked across the desert, two uniformed figures remaining behind long enough to cover the jet-copter with an ochre-colored tarpaulin which would effectively camouflage it from the air. It was like something from the Arabian Nights, Alan thought as they approached a low, rocky escarpment thrusting up through the sand. The leader of the militiamen placed his hand against a polished spot on the surface of the rock, which pulsed with the contact as a hidden device checked the pattern and whorls of the militiaman's fingerprints. The effect was the same as the Open Sesame of the Arabian Nights, for a great slab-like section of the escarpment rolled ponderously aside, revealing a dark cavity.

"Red Sands," the militiaman said proudly, and led the way inside.

Alan was totally unprepared for what happened next. The door in the rock rolled shut behind them. Lights blazed inside the cavern, brighter than the pale Martian day. A throbbing, busy city was spread out before them below the surface of Mars.

Throngs of men, women and children lined the short road to the city on both sides. A great cry went up from them as Alan, the militiamen, General Olmstead and his daughter approached.

"Hail, Tremaine!" The cry echoed from the rock walls of the underground city. "Hail, Tremaine!" It rolled from the far throbbing reaches of the bustling city. "Tremaine, Tremaine, Tremaine!"

Not for me, Alan thought. For my father. What actually did he know about all this? Perhaps a revolution directed from the secret base here at Red Sands had been his father's secret dream. The adulation with which the people of Red Sands greeted him filled him with a sense of pride. Not for his own accomplishments, but for his father's. Laura Olmstead was, quite suddenly and unexpectedly, part of a different world. Alan shrugged, deciding to suspend judgment until he met and talked with Bennett Keifer.
