She hesitated, just for a second. Then she looked at Dio and said, "Yes."

Gray turned. Almost lazily, his fist snapped up and took Caron on his flabby jaw.

"Take care of him, Dio," he grunted. Then he entered the ship, herding the white-faced girl before him.

The ship hurtled up into airless s.p.a.ce, where the blinding sunlight lay in sharp shadows on the rock. Over the ridge and down again, with the Project hidden under a surf of storm-clouds.

Cutting in the air motors, Gray dropped. Black, bellowing darkness swallowed them. Then he saw the valley, with the copper cables fallen, and the wheat already on fire in several places.

Flying with every bit of his skill, he sought the narrowest part of the valley and flipped over in a racking loop. The stern tubes. .h.i.t rock. The nose slammed down on the opposite wall, wedging the ship by sheer weight.

Lightning gathered in a vast javelin and flamed down upon them. Jill flinched and caught her breath. The flame hissed along the hull and vanished into seared and blackened rock.

"Still willing to die for principle?" asked Gray brutally.

She glared at him. "Yes," she snapped. "But I hate having to die in your company!"

She looked down at the valley. Lightning struck with monotonous regularity on the hull, but the valley was untouched. Jill smiled, though her face was white, her body rigid with waiting.

It was the smile that did it. Gray looked at her, her tousled black curls, the lithe young curves of throat and breast. He leaned back in his seat, scowling out at the storm.

"Relax," he said. "You aren't going to die."

She turned on him, not daring to speak. He went on, slowly.

"The only chance you took was in the landing. We're acting as lightning rod for the whole valley, being the highest and best conductor. But, as a man named Faraday proved, the charge resides on the surface of the conductor. We're perfectly safe."

"How dared you!" she whispered.

He faced her, almost angrily.

"You knocked the props out from under my philosophy. I've had enough hypocritical eyewash. I had to prove you. Well, I have."

She was quiet for some time. Then she said, "I understand, Duke. I'm glad. And now what, for you?"

He shrugged wryly.

"I don't know. I can still take Caron's other ship and escape. But I don't think I want to. I think perhaps I'll stick around and give virtue another whirl."

Smoothing back his sleek fair hair, he shot her a sparkling look from under his hands.

"I won't," he added softly, "even mind going to Sunday School, if you were the teacher."
