They were taken out another way, where three heavy trucks and several smaller vehicles were drawn up. The Senyans in them wore a distinctive harness and were armed, and the vehicles all had armor plated bodies. Durham and Karlovic were lifted into one of the trucks, which was already filled with Senyan soldiers. The convoy moved off. Durham braced himself in a corner and looked at Karlovic. "Happened fast, didn't it? Awfully fast." "Violent things always do. You're not much used to violence, are you? Neither am I. Neither are most people. They get it shoved at them." "I don't think we're through with it yet," said Durham. Karlovic said, "I told you." For some time there was only the rushing and jolting of the truck, the roar of motors and a kind of dim uneasy background of sound as though the whole city stirred and seethed. Durham was frightened. The food he had eaten had turned against him, he was stifling in his own sweat, and he thought of Morrison cruising comfortably somewhere out in space, smoking cigarettes and drinking good whiskey and sending down a message now and then, the way a man pokes with a stick at a brace of beetles, stirring them casually toward death. He ground his jaws together in an agony of hate and fear, and the taste of them was sour in his mouth. Somebody said to them, "We're on the spaceport highway now. It won't be long." A minute later somebody shouted and Karlovic caught the Senyan word and echoed it. "Barricade!" The truck rocked and whirled about and there were great crashes in the night that had fallen. Durham was thrown to his knees. The truck raced at full speed. There were sounds of fighting that now rose and now grew faint, and the truck lurched and swerved, and then there were more roars and crashes and it came violently to a halt. The Senyans began firing out of the loopholes in the armored sides. Some of them leaped out of the truck, beckoning Durham and Karlovic to come after them. A large force of rioters was attacking what remained of the convoy, which had been forced back into the city. Four of the Senyan soldiers ran with the two men into a side street, but a small body of rioters caught up with them. The soldiers turned to fight, and Karlovic said in a voice that was now curiously calm, "If we're quick enough they may lose sight of us in the darkness." He turned into an areaway between two buildings, and then into another, and Durham ran beside him through the cold green mist and the dim glow of lamps that glimmered on the alien walls. The sound of the fighting died away. They turned more corners, hunting always for the darkest shadows, hoping to meet a patrol. But the streets were deserted and all the doors barred tight. Finally Durham stopped. "How much oxygen you got left?" Karlovic peered at the illuminated indicator on the wrist of his suit. "Hour. Maybe less." Both men were breathing hard, panting, burning up the precious stuff of life. Durham said,
