Outside the enclosure, a squat, fat man, the perspiration rolling in streams down his face, tugged at his collar with frantic, nervous jerks, as he leaned in over the side of a high-powered car, and with his other hand gripped at the arm of the young man in the driver's seat. "Dave, listen to 'em! My God, listen to 'em!" snarled the fat man. Dave Henderson, with the toe of his boot, moved the little black satchel that the other had dropped on the floor of the car farther to one side; and, by way of excuse for disengaging his arm, reached into his pocket for his cigarettes.
