Dave was on the roof of the cab, wedged between the light bar and the slope of the ambulance. He leaned over the driver’s side. There was a big side mirror there. He could see an ugly black-bearded man, driving and shouting. He knew the man was going to hurt Jamie. He could see the man baring his teeth in a sign of rage. Dave leaned down, resting his weight on the side mirror, and swung his arm in through the open window. His strong fingers grabbed the bearded man by the nose, and the man yelled and jerked his head. Dave’s fingers slipped, but he lunged back and bit down hard on the man’s ear, and held on. The man was screaming at him in rage. Dave could feel that rage, but he had plenty of his own. He pulled hard, and felt the ear come away with a gush of hot blood. The man screamed, and spun the wheel. The ambulance tilted, the left wheels came up off the ground, and the vehicle slowly turned over and crashed down on its right side. The sound of screeching metal was incredibly loud.
