A needle of blue light jutted from either end of the big gun and made smoking trenches in the opposite wall of the garage and the wall behind them. Then Billig brought the gun steadily downward, lengthening the forward and rearward trenches. The air smelled acid, as if laced with ozone. The blue beam dimmed the bright lights and made everything shadowy.

The green cat still looked up at Billig curiously. Billig didn't look straight back at it. The little muscles in his jaw and temple bulged around the hand clamping shut his mouth and nose.

The forward trench dug itself across the wall and floor, swung drunkenly past Mitzie and the doddering jeep, got ten feet from the green cat and hesitated. It swung this way and that, as if it had encountered a magic circle it couldn't pierce—and stopped.

Jack murmured, "Sash was right."

Billig gave a great gasp and began to squeal.

The blue beams winked out. The gun clanked on the floor. The squeal changed to a clucking and Billig swayed. Jack jumped to catch him.

Phil sprang forward and his fingers touched buttons he'd seen Billig touch. The bars in the garage gateways shot up. Phil was on the telescoped stairs almost before they began to move, and rode them to the ground through layers of stinging ozone and golden harmony. The jeep had trembled to a stop just short of Mitzie, who stared at it groggily, her whole figure slack, as if a puff of wind could have felled her.

When the stairs touched the floor, momentum carried Phil forward a half dozen steps but he kept his footing and circled back at a run. When he plunged into the area between the green cat and the spot where the jeep had been abandoned, he felt a shiver of sudden and extreme terror, which even as he felt it, began to fade.

But he hardly had time to ask himself whether that was what had stampeded Carstairs and the rest, for the next instant he was calling, "Lucky!" and Lucky was saying "Prrt!" and he was scooping up the unresisting cat, his fingers trembling as they touched the green fur, and darting back toward Mitzie and the jeep. Her groggy look had now become a dazed smile of triumph and pride.

He grabbed her by the elbow and pulled her toward the jeep. "Get in!" he shouted in her ear. "We're getting out of here. You're driving."
