been here to steady it." Her father? "You seem determined to punish me," he said unsteadily. He could hear the ambulance car rocketing across the field now. They were coming for Jerry. "I'll go on punishing you," she said. "If it hadn't been for you, Dad wouldn't be dead now, laying over there in that ship." Dad? Jerry Graham? "You're not...?" Her nod was barely discernible. "Jerry Graham lived on Vestena for many years," she said. "When mother died, he put me into a community school. He came here. He never told anyone...." Her voice broke. "Through my father, I worshipped you. It's all dead now. If I can find a way to hurt you, I'll do it." She whirled and was gone, a slim, windswept figure in the vast darkness of the field. He started to run after her. Then he saw the tiny, sport-model rocket plane parked at the edge of the apron. She was in it and the rockets were exploding before he could reach her. She waved her arm at him as the ship leaped forward. She shouted something that was drowned in the roar of rocket exhaust. Then she was gone. Peter Folley was talking. "The jig's up, Blair. The Vestena merchants have signed an oath to refuse further trade with Parma. You know what that means?" Blair Freedman nodded. It didn't make any difference to him now. Not, at least, until he found Sheila Graham and made her understand how he really felt about Jerry's death. "I suppose we'll close the tunnel?" Folley shook his head and frowned. "No, that's the bad part of it. We've got to hold the tunnel open." He leaned forward, tapping his pencil.
