Kieran said, "I'll keep her quiet."

He took her from Bregg. She collapsed against him and began to cry. "Murderers," she whispered. "That little girl, those old people—"

Webber said, "You could exterminate those beasts. You don't have to let them hunt the people like that. It's—it's—"

"Unhuman is the word you want," said Bregg. His voice was exceedingly weary. "Please get into the car."

They climbed in. The car churned around and sped back toward the building. Paula shivered, and Kieran held her in his arms. Webber said after a moment or two, "How did you happen to be here, Bregg?"

"When we caught the flitter and found it empty, it was obvious that you were with the people, and it became imperative to find you before you came to harm. I remembered that the trail ran close by this old outpost building, so I had the patrol ship drop us here with an emergency vehicle."

Kieran said, "You knew the people were coming this way?"

"Of course." Bregg sounded surprised. "They migrate every year at the beginning of the dry season. How do you suppose Webber found them so easily?"

Kieran looked at Webber. He asked, "Then they weren't running from the Sakae?"

"Of course they were," Paula said. "You saw them yourself, cowering under the trees when the ship went over."

"The patrol ships frighten them," Bregg said. "Sometimes to the point of stampeding them, which is why we use them only in emergencies. The people do not connect the ships with us."

"That," said Paula flatly, "is a lie."

Bregg sighed. "Enthusiasts always believe what they want to believe. Come and see for yourself."

She straightened up. "What have you done to them?"

"We've caught them in a trap," said Bregg, "and we are presently going to stick needles into them—a procedure necessitated by your presence, Doctor Ray. They're highly susceptible to imported viruses, as you should remember—one of your little parties of do-gooders succeeded in wiping out a whole band of them not too many years ago. So—inoculations and quarantine."
