Operation Terror by Murray Leinster (top 10 most read books in the world .txt) 📗

was its birthplace and its home. It moved with great deliberation toward the small town of Maplewood, twenty miles from the border of the Park.

Jeeps and motorcycles scurried ahead of it, just out of reach of its beams. They made sure that houses and farms and all inhabited places were emptied of people before the moving terror beams could engulf them. They went into the town of Maplewood itself and frantically made sure that nothing alive remained in it. They went on to clear the countryside beyond.[85]

The unseen thing from the Park moved onward. High overhead there was a dull muttering like faraway thunder, but it was planes with filled bomb racks circling above the starlit land. There were men in those planes who ached to dive down and destroy this separated fraction of an invasion. But there were firm orders from the Pentagon. So long as the invaders killed nobody, they were not to be attacked. There was reason for the order in the desire of the government to be on friendly terms with a race which could travel between the stars. But there was an even more urgent reason. The aliens had not yet begun to murder, but it was suspected that they had a horrifying power to kill. So it was firmly commanded that no bomb or missile or bullet was to be used unless the invaders invited hostilities by killing humans. Their captives—the crew of a helicopter—might be freed if aliens and men achieved friendship. So for now—no provocation!

The thing which nobody saw moved comfortably over the ground between the park and Maplewood. In the center of the weapon field there was a something which generated the terror beam and probably carried passengers. Whatever it was, it moved onward and into Maplewood and for seven miles in every direction troops watched for it to move out again. Artillerymen had guns ready to fire upon it if they ever got firing coordinates and permission to go into action. Planes were ready to drop bombs if they ever got leave to do so. And a few miles away there were rockets ready to prove their accuracy and devastating capacity if only given a launching command. But nothing happened. Not even a flare was permitted to be dropped by the planes far up in the sky. A flare might be taken for hostility.

The thing from the Park stayed in Maplewood for[86] two hours. At the end of that time it moved deliberately back toward the Park. It left the town untouched save for certain curious burglaries of hardware stores and radio shops and a garage or two. It looked as if intensely curious not-human beings had moved from their redoubt—Boulder Lake—to find out what civilization human beings had attained. They could guess at it by the buildings and the homes, but most notably in the technical shops of the inhabitants.

It went slowly and deliberately back into the Park. Humans moved cautiously back into the area that had been emptied. Not many, but enough to be sure that the thing had really returned to the place from which it had come. Soldiers were tentatively entering the again-abandoned town of Maplewood when the unseen thing changed the range of its weapon bearing on that little city. It was then presumably not less than seven miles on its way back to Boulder Lake. The military had congratulated themselves on what they'd learned. The beam projectors at the lake had a range of much more than seven miles, but this movable, unidentifiable thing carried a lesser armament. From it, men and animals seven miles away were safe. This was notable news.

Then the unseen object did something. The terror beam that flicked back and forth doubled in intensity. The soldiers just reentering Maplewood smelled foulness and saw bright lights. Bellowings deafened them. They fell with every muscle rigid in spasm. Beyond them other men were paralyzed. For five minutes the invaders' mobile weapon paralyzed all living things for a distance of fifteen miles. Then for thirty seconds it paralyzed living things for a distance of thirty miles. For a bare instant it convulsed men and animals for a greater distance[87] yet. And all these victims of the terror beam knew, thereafter, an invincible horror of the beam.

The thing from the Park which nobody had seen went back into the Park. And then men were permitted to return to exactly the same places they'd been allowed to occupy before the thing began its excursion.

It seemed that nothing was changed, but everything was changed. If there were mobile carriers of the invasion weapon, then victory could not be had by a single atom bomb fired into Boulder Lake. There might be a dozen separate mobile terror beam generators scattered through the Park. Any atomic attack would need to be multiplied in its violence to be certain of results. Instead of one bomb there might be a need for fifty. They would have to destroy the Park utterly, even its mountains. And the fallout from so many atom bombs simply could not be risked. The invaders were effectively invulnerable.

While this undesirable situation was being demonstrated, Jill slept heavily between two roots of a very large tree, and Lockley dozed against a nearby tree trunk. He believed that he guarded Jill most vigilantly.

He awoke at dawn with the din of bird song in his ears. Jill opened her eyes at almost the same instant. She smiled at him and tried to get up. She was stiff and sore from the hardness of the ground on which she'd slept. But it was a new day, and there was breakfast. It was porcupine cooked the night before.

"Somehow," said Jill as she nibbled at a bone, "somehow I feel more cheerful than I did."

"That's a mistake," Lockley told her. "Start out with a few premonitions and the day improves as they turn out wrong. But if you start out hoping,[88] the day ends miserably with most of your hopes denied."

"You've got premonitions?" she asked.

"Definitely," he said.

It was true. As yet he knew nothing of last night's temporary occupation of a human town, but he believed he knew how the terror beam worked even if he couldn't figure out a way to generate it. He could imagine no defense against it. But if Jill had awakened feeling cheerful, there was no reason to depress her. She'd have reason enough to be dejected later, beginning with proof of Vale's death and going on from there.

"We might listen to the news," she suggested. "A premonition or two might be ruled out right away!"

Silently, he turned on the little radio. Automatically, he set it for the lowest volume they could hear distinctly.

The main item in the news was a baldly factual but toned-down report of the thing from the lake which had left the park and examined a small human town in detail and then had returned to the Park. There were reports of peculiar hoofprints found where the invaders had been. They were not the hoofprints of any earthly animal. There was an optimistic report from the scientists at work on the problem of the beam. Someone had come up with an idea and some calculations which seemed to promise that the beam would presently be duplicated. Once it was duplicated, of course a way to neutralize it could be found.

Lockley grunted. The broadcast was enthusiastic in its comments on the scientists. It talked gobbledegook which sounded as if it meant something but was actually nonsense. It barely touched on the fact that human beings were now ordered out of a much larger space than had been evacuated before. There[89] was a statement from an important official that panic buying of food was both unnecessary and unwise. Lockley grunted again when the newscast ended.

"The idea that anything that can be duplicated can be canceled," he announced gloomily, "is unfortunately rot. We can duplicate sounds, but there's no way to make them cancel out! Not accurately!"

Jill had eaten a substantial part of the porcupine while the newscast was on. It was not a satisfying breakfast, but it cheered her immensely after two days of near-starvation.

"But," she observed, "maybe that won't apply to this business when you report what you know. It's not likely that anybody else has stood just outside a beam and made tests of what it's like and how it's aimed and so on."

They started off. For journeying in the Park, Lockley had the advantage that as part of the preparation for making a new map, he'd familiarized himself with all mapping done to date. He knew very nearly where he was. He knew within a close margin just where the terror beam stretched. He'd smashed his watch, which during sunshine substituted admirably for a compass, but he could maintain a reasonably straight line toward that part of the Park's border the terror beam would cross.

They moved doggedly over mountain-flanks and up valleys, and once they followed a winding hollow for a long way because it led toward their destination without demanding that they climb. It was in this area that, pushing through brushwood beside a running stream, they came abruptly upon a big brown bear. He was no more than a hundred feet away. He stared at them inquisitively, raising his nose to sniff for their scent.

Lockley bent and picked up a stone. He threw it.[90] It clattered on rocks on the ground. The bear made a whuffing sound and moved aggrievedly away.

"I'd have been afraid to do that," said Jill.

"It was a he-bear," said Lockley. "I wouldn't have tried it on a she-bear with cubs."

They went on and on. At mid-morning Lockley found some mushrooms. They were insipid and only acute hunger would make them edible raw, but he filled his pockets. A little later there were berries, and as they gathered and ate them he lectured learnedly on edible wild plants to be found in the wilderness. Jill listened with apparent interest. When they left the berry patch they swung to the left to avoid a steep climb directly in their way. And suddenly Lockley stopped short. At the same instant Jill caught at his arm. She'd turned white.

They turned and ran.

A hundred yards back, Lockley slackened his speed. They stopped. After a moment he managed to grin mirthlessly.

"A conditioned reflex," he said wryly. "We smell something and we run. But I think it's the old familiar terror beam that crosses highways to stop men from using them. If it were a portable beam projector with somebody aiming it, we wouldn't be talking about it."

Jill panted, partly with relief.

"I've thought of something I want to try," said Lockley. "I should have tried it yesterday when I first smashed my watch."

He retraced his steps to the spot where they'd caught the first whiff of that disgusting reptilian-jungle-decay odor which had bombarded their nostrils. Jill called anxiously, "Be careful!"

He nodded. He got the coiled bronze watchspring out of his pocket. He went very cautiously to the spot where the smell became noticeable. Standing well[91] back from it, he tossed one end of the spring into it. He drew it back. He repeated the operation. He moved to one side. Again he swung the gold-colored ribbon. He dangled it back and forth. Then he drew back yet again and wrapped his left hand and wrists with many turns of the thin bronze spring, carefully spacing the turns. He moved forward once more.

He came back, his expression showing no elation at all.

"No good," he said unhappily. "In a way, it works. The spring acts as an aerial and picks up more of the beam than my hand. But I tried to make a Faraday cage. That will stop most electromagnetic radiation, but not this stuff! It goes right through, like electrons through a radio tube grid."

He put the spring back in his pocket.

"Well," he grimaced. "Let's go on again. I had a little bit of hope, but some smarter men than I am haven't got the right gimmick yet."

They started off once more. And this time they did not choose a path for easier travel, but went up a steep slope that rose for hundreds of feet to arrive at a crest with another steep slope going downhill. At the top Lockley said sourly, "I did discover one thing, if it means anything. The beam leaks at its edges, but it's only leakage. It doesn't diffuse. It's tight. It's more like a searchlight beam than anything else in that way. You can see a light beam at night because dust motes scatter some part of it. But most of the light goes straight on. This stuff does the same. It's hard to imagine a limit to its range."

He trudged on downhill. Jill followed him. Presently, when they'd covered two miles or more
