Lupe made a swift move for which Travis was ready. His grip on the other's body helped to tumble them both around a rock which lay between them and the Red. There was the crack of another shot and dust spurted from the side of the boulder. But they lay together, safe for the present, as Travis was sure the enemy would not risk an open attack on their small fortress.

With Travis' aid Lupe struggled back up to the site where Nolan waited. Jil-Lee was there to make competent examination of the boy's wound.

"Creased," he reported. "A sore head, but no great damage. Perhaps a scar later, warrior!" He gave Lupe an encouraging thump on the shoulder, before plastering an aid pack over the cut.

"Now we go!" Nolan spoke with emphatic decision.

"He saw enough of us to know we are not Tatars."

Nolan's eyes were cold, his mouth grim as he faced Travis.

"And how can we fight him—?"

"There is a wall—a wall you cannot see—about him," Lupe broke in. "When I would strike at him, I could not!"

"A man with invisible protection and a gun," Jil-Lee took up the argument. "How would you deal with him, younger brother?"

"I don't know," Travis admitted. Yet he also believed that if they withdrew, left the Red here to be found by his own people, the enemy would immediately begin an investigation of the southern country. Perhaps, pushed by their need for learning more about the Apaches, they would bring the helicopter in over the mountains. The answer to all Apache dangers, for now, lay in the immediate future of this one man.
