His voice, grown shrill and sharp, was chopped off by the explosion. It was a noise such as Terry had never heard before--like a tremendously condensed and powerful puff of wind. There was not a sharp jar, but he felt an invisible pressure against his body, taking his breath. The sound of the explosion was dull, muffled, thick. The door of the safe crushed into the flooring. Terry had nerved himself for two points of attack--Lewison from the front of the building, and the guard at the rear. But Lewison did not yell for help. He had been dangerously close to the explosion and the shock to his nerves, perhaps some dislodged missile, had flung him senseless on the sand outside the bank. But from the rear of the building came a dull shout; then the door beside which Terry stood was dragged open--he struck with all his weight, driving his fist fairly into the face of the man, and feeling the knuckles cut through flesh and lodge against the cheekbone. The guard went down in the middle of a cry and did not stir. Terry leaned to shake his arm--the man was thoroughly stunned. He paused only to scoop up the fallen revolver which the fellow had been carrying, and fling it into the night. Then he turned back into the dark bank, with Red and Pat cursing in frightened unison as they cowered against the wall behind him. The air was thick with an ill-smelling smoke, like that of a partially snuffed candle. Then he saw a circle of light spring out from the electric lantern of Denver and fall on the partially wrecked safe. And it glinted on yellow. One of the sacks had been slit and the contents were running out onto the floor like golden water. Over it stooped the shadow of Denver, and Terry was instantly beside him. They were limp little sacks, marvellously ponderous, and the chill of the metal struck through the canvas to the hand. The searchlight flickered here and there--it found the little drawer which was wrenched open and Denver's stubby hand came out, choked with greenbacks. "Now away!" snarled Denver. And his voice shook and quaked; it reminded Terry of the whine of a dog half-starved and come upon meat--a savage, subdued sound. There was another sound from the street where old Lewison was coming to his senses--a gasping, sound, and then a choked cry: "Help!" His senses and his voice seemed to return to him with a rush. His shriek split through the darkness of the room like a ray of light probing to find the guilty: "Thieves! Help!" The yell gave strength to Terry. He caught some of the burden that was staggering Denver into his own arms and floundered through the rear door into the blessed openness of the night. His left arm carried the crushing burden of the canvas sacks--in his right hand was the gun--but no form showed behind him.
