Monk's smile faded. No, he thought, he hadn't acted too wisely. He'd expected the frightened girl to leap out of the sandcar and race away on her lozelle—and she had. But he hadn't expected her to return an hour later with a dozen revenge-hungry tribesmen. His mistake had been in letting her escape. He cursed silently. Then he spat. After all, it was over and done. The Martians had trussed him, buried him, and left him to die—but he'd at least been wise enough not to reveal his ace in the hole. His partner, old Stardust Luke, had left yesterday in the auxiliary sandcar to get fresh supplies from Chandler Field. Old Stardust was as honest as a baby and methodical as a clock.

He could imagine himself in a cool, dark bar on Earth, surrounded by smiling women, sipping iced drinks. "Ahhh," he breathed, opening his eyes. Then he saw the Aab. It squatted on a small, irregular-shaped dune some three feet from him in the
