Nick counted the days as he doled out the water from the canteens they had refilled in the underground lake. His concentrated emergency rations, shared with Susan and Klev, gave out at last. The Martian did not drink, but finally the last trickle of water went down Susan's throat and the period of torture began.

Nick slept during the torrid days now, panting and itching and thirst-tormented beneath an overhanging rock, and through the nights lay on the edge of the bowl watching the sky. They did not talk much, for the effort hurt their parched throats.

It seemed a vision born of wishful thinking when at last the distinctive fan-shaped trail of a spaceship showed against the stars, dim at first but steadily growing brighter. And then it was in the upper atmosphere, the scream of the braking jets rising and falling as the pilot jockeyed the throttles. Down it came in a flaming arc, to land amid the beckoning lights of Central Camp.

"What do we do now?" Susan asked.

"Steal it."

"But how?"

Nick shook his head wearily. "Wait for the Martians to attack. Then try to break through."

"But the barrier? We'll be killed too, just like the Martians."

He looked at her sharply.

"I'm going with you, of course."
