Birrel looked ahead, saw the sign that marked a crossroad, and said, "Turn there!"

Next moment, he thought they were all three done for. For Holmer turned into the dark side road without slowing down at all, and the sedan careened on screaming tires and threatened to go over.

Birrel, slammed into a corner of the back seat, felt Kara bump against him. He held her with one arm and groped frantically for something to hold onto when they rolled over.

They didn't roll over. By scared reaction, Holmer spun the wheel at the right second. The sedan tottered, then thumped back onto all four wheels, its motor stalled.

Out on the main highway, a car flashed by fast.

"These cursed Earth vehicles!" said Holmer, in a shaky voice. "No gyroscopic controls, no built-in stability factor at all!"

Birrel felt like yelling, "What the devil made you think you could turn a right angle at full speed?" But he didn't. It would give him away, as Rett he mustn't know too much more about automobiles than the others did.

But for the sake of survival he had to get Holmer away from the wheel.

He said, "Let me drive it—since I saw you last I've learned to handle them pretty well."

Holmer crowded over in the front seat, holding the black box in his lap. Birrel climbed over fast, and took the wheel.
