He didn’t want to let her go, but he had to. He grabbed the rifle again, pointed it at the wagon. Military routine, he thought, and then, military fiddlesticks. But since he wore a corporal’s stripes these days, he played the game by the rules. “Come on out, boys,” he called.

Ristin and Ullhass, the two Lizard POWs who accompanied the Metallurgical Laboratory’s wagon train on the way from Chicago to the Lab’s planned new home in Denver, poked their heads up over the side of the wagon. “It shall be done, superior sir,” they chorused in hissing English. They dropped down in front of Yeager and Barbara.

“Hard to think-things-so small could be so dangerous,” Barbara murmured. Neither of the Lizards came up even to her shoulder.

“They aren’t small with guns in their hands, or inside tanks, or inside planes, or inside their spaceships,” Yeager answered. “I fought against them, remember, before my unit captured these boys.”

“We thought you kill us,” Ullhass said.

“We thought you kill us, then eat us,” Ristin agreed.

Yeager laughed. “You’d been reading too much science fiction, both of you.” He laughed again, more reflectively. If he hadn’t been in the habit of reading science fiction himself to pass the time on trains and buses, he never would have volunteered-or been accepted-as the Lizards’ principal guard, translator, and explainer of matters Earthly.

He’d been with them continuously for better than six months now, long enough to come to see them as individuals rather than mere creatures. They never had been much like the bug-eyed monsters he used to read about. They were short and skinny and, even dressed in multiple layers of warm clothes that hung on them like sacks, complained all the time about how cold it was (it wasn’t just midwinter on the northern Great Plains, either; they’d complained about all but the hottest days back in Chicago, too).
