Everything was lost now—even the hills.

Unless ... one chance. The only chance, and it was nearly hopeless.

"Get in the back, Lisa," he said. "Climb over the seat and hide in that storage compartment. And stay there."

The two nearest cars had swung about now and paralleled his course, flanking him, drifting in nearer and nearer.

"Why?" Lisa clung to him. "What are you going to do?"

"They don't know you're with me. They probably don't even know I went back to the canyon. They think I'll land at the museum, not suspecting anything's wrong. So I'll do just what they expect me to. Go back, and pretend I don't know a thing."

"You're mad."

"It's our only chance, Lisa. If only they don't lock me up tonight...."

She clung to him for still another minute and then she climbed over the seat and he heard the luggage compartment panel slide open and, a moment later, shut.

The nearest aircar drifted still closer to him, escorting him west-ward, toward the museum. Behind him, other cars closed in.
