Astro nodded.

"Must be more of those Solar Guardsmen," said the guard, relaxing. "We have two of them in here, another in the hospital, and one of them working in the machine shop."

Hospital! Astro gulped. That would be Roger. But he dared not ask too many questions. "What's going to happen to them?" he asked casually.

"I don't know," said the guard, "but I wish we'd hurry up and attack Venusport. I'm getting tired of living out here in the jungle."

"Me too," said Astro. "Well, you'd better get going."

The guard nodded and started to walk away. Suddenly Astro stiffened. Two other guards were rounding the corner of the building. He called to the departing guard quickly. "Who's on duty with you tonight?"

"Maron and Teril," replied the guard, and then strode off into the darkness.

"So long," said Astro, turning to face the two men walking toward him. He would have to get rid of them.

"Hello, Maron, Teril," he called casually. "Everything quiet?"
