As he approached the farm where he had spent the past few days, he saw two passenger-vehicles standing by the road. One was a black one, similar to the one in which the physician had come to the farm, and the other was white with black trimmings and bore the same device he had seen on the cap of the policeman. A policeman was sitting in the driver’s seat of this vehicle, and another policeman was standing beside it, breathing smoke with one of the white paper cylinders these people used. In the farmyard, two men were going about with a square black box; to this box, a tube was connected by a wire, and they were passing the tube about over the ground.
The policeman who was standing beside the vehicle saw him approach, and blew his whistle, then drew the weapon from his belt. Hradzka, who had been expecting some attempt to halt him, had let go the right-hand steering handle and drawn his own weapon; as the policeman drew, he fired at him. Without observing the effect of the shot, he sped on; before he had rounded the bend above the farm, several shots were fired after him.
A mile beyond, he came to the place where he had hidden the blaster. He stopped the vehicle and jumped off, plunging into the brush and racing toward the hollow tree. Just as he reached it, he heard a vehicle approach and stop, and the door of the police vehicle slam. Hradzka’s fingers found the belt of his blaster; he dragged it out and buckled it on, tossing away the missile weapon he had been carrying.
Then, crouching behind the tree, he waited. A few moments later, he caught a movement in the brush toward the road. He brought up the blaster, aimed and squeezed the trigger. There was a faint bluish glow at the muzzle, and a blast of energy tore through the brush, smashing the molecular structure of everything that stood in the way. There was an involuntary shout of alarm from the direction of the road; at least one of the policemen had escaped the blast. Hradzka holstered his weapon and crept away for some distance, keeping under cover, then turned and waited for some sign of the presence of his enemies. For some time nothing happened; he decided to turn hunter against the men who were hunting him. He started back in the direction of the road, making a wide circle, flitting silently from rock to bush and from bush to tree, stopping often to look and listen.
This finally brought him upon one of the policemen, and almost terminated his flight at the same time. He must have grown overconfident and careless; suddenly a weapon roared, and a missile smashed through the brush inches from his face. The shot had come from his left and a little to the rear. Whirling, he blasted four times, in rapid succession, then turned and fled for a few yards, dropping and crawling behind a rock. When he looked back, he could see wisps of smoke rising from the shattered trees and bushes which had absorbed the energy-output of his weapon, and he caught a faint odor of burned flesh. One of his pursuers, at least, would pursue him no longer.
He slipped away, down into the tangle of ravines and hollows in which he had wandered the day before his arrival at the farm. For the time being, he felt safe, and finally confident that he was not being pursued, he stopped to rest. The place where he stopped seemed familiar, and he looked about. In a moment, he recognized the little stream, the pool where he had bathed his feet, the clump of seedling pines under which he had slept. He even found the silver-foil wrapping from the food concentrate capsule.
But there had been a change, since the night when he had slept here. Then the young pines had been green and alive; now they were blighted, and their needles had turned brown. Hradzka stood for a long time, looking at them. It was the same blight that had touched the plants around the farmhouse. And here, among the pine needles on the ground, lay a dead bird.
It took some time for him to admit, to himself, the implications of vegetation, the chickens, the cow, the farmer and his wife, had all sickened and died. He had been in this place, and now, when he had returned, he found that death had followed him here, too.
During the early centuries of the Atomic Era, he knew, there had been great wars, the stories of which had survived even to the Hundredth Century. Among the weapons that had been used, there had been artificial plagues and epidemics, caused by new types of bacteria developed in laboratories, against which the victims had possessed no protection. Those germs and viruses had persisted for centuries, and gradually had lost their power to harm mankind. Suppose, now, that he had brought some of them back with him, to a century before they had been developed. Suppose, that was, that he were a human plague-carrier. He thought of the vermin that had infested the clothing he had taken from the man he had killed on the other side of the mountain; they had not troubled him after the first day.
There was a throbbing mechanical sound somewhere in the air; he looked about, and finally identified its source. A small aircraft had come over the valley from the other side of the mountain and was circling lazily overhead. He froze, shrinking back under a pine-tree; as long as he remained motionless, he would not be seen, and soon the thing would go away. He was beginning to understand why the search for him was being pressed so relentlessly; as long as he remained alive, he was a menace to everybody in this
