“ Peter cagily backed away. The wizard hurled himself in a bruising body-block against Peter, battering him off his feet and falling on the young man. Instinctively Peter bridged his body, arching it off the floor. Almarish, grunting fiercely, gripped his arm and turned it slowly, as though he were winding a clock. Peter snapped over, rolling on the wizard's own body as a fulcrum. He had his toe in his hand, and closed his fist with every ounce of muscle he had. The sorcerer screamed and fell over on his face. Peter jammed his knee in the wizard's inside socket and bore down terribly. ”
