The whole earth had the jitters because of the apparently inevitable trial of strength between its two most gigantic powers. Their rivalry seemed irreconcilable. Most of humanity dreaded their conflict with appalled resignation because there seemed no way to avoid it. Yet it was admittedly possible that an all-out war between them might end with all the world dead, even plants and microbes in the deepest seas. It was ironic that the most reasonable hope that anybody could have was that one or the other nation would come upon some weapon so new and irresistible that it could demand and receive the surrender of the other without atomic war.
Atom bombs could have done the trick, had only one nation owned them. But both were now armed so that by treacherous attack either could almost wipe out the other. There was no way to guard against desperate and terrible retaliation by survivors of the first attacked country. It was the certainty of retaliation which kept the actual war a cold one—a war of provocation and trickery and counter-espionage, but not of mutual extermination.
But Lockley had suggested—because it was the worst of possibilities—that America's rival had developed a new weapon which could win so long as it was not attributed to its user. If the United States believed itself attacked from space, it would not launch missiles against men. It would ask help, and help would be given even by its rival if the invasion were from another planet. Men would always combine against not-men. But if this were a ship from no farther than the other side of the earth, and only pretended to be from an alien world ... America could be conquered because it believed it was fighting monsters instead of other men.
This was not likely, but it was believable. There was no proof, but in the nature of things proof would be avoided. And if his idea should happen to be true, the disaster could be enormously worse than an invasion from another star. This first landing could be only a test to make sure that the new weapon was unknown to America and could not be countered by Americans. The crew of this ship would expect to be successful or be killed. In a way, if an atom bomb had to be used to destroy them, they would have succeeded. Because other ships could land in American cities where they could not be bombed without killing millions; where they could demand surrender under pain of death. And get it.
Lockley looked at the sun. He glanced at his watch.
"That would be south," he indicated. "It's the shortest way for us to get to where you'll be reasonably safe and I can tell what I know to someone who may use it."
Jill followed obediently. They disappeared into the woods. They could not be seen from the highway. They could not even be detected from aloft. When they had gone a mile, Jill made her one and final protest.
"But it can't be that they aren't monsters! They must be!"
"Whatever they are," said Lockley, "I don't want them to lay hands on you."
They went on. Once, from the edge of a thicket of trees, they saw the highway below them and to their left. It was empty. It curved out of sight, swinging to the left again. They moved uphill and down. Now the going was easy, through woods with very little underbrush and a carpet of fallen leaves. Again it was a sunlit slope with prickly bushes to be avoided. And yet again it was boulder-strewn terrain that might be nearly level but much more often was a hillside.
Lockley suddenly stopped short. He felt himself go white. He grasped Jill's hand and whirled. He practically dragged her back to the patch of woods they'd just left.
"What's the matter?" The sight of his face made her whisper.
He motioned to her for silence. He'd smelled something. It was faint but utterly revolting. It was the smell of jungle and of foulness. There was the musky reek of reptiles in it. It was a collection of all the smells that could be imagined. It was horrible. It was infinitely worse than the smell of skunk.
Silence. Stillness. Birds sang in the distance. But nothing happened. Absolutely nothing. After a long time Lockley said suddenly, "I've got an idea. It fits into that broadcast. I have to take a chance to find out. If anything happens to me, don't try to help me!"
He'd smelled the foul odor at least fifteen minutes before, and had dragged Jill back, and there had been no other sign of monsters or not-monsters upon the earth. Now he crouched down and crawled among the bushes. He came to the place where he'd smelled the ghastly smell before. He smelled it again. He drew back. It became fainter, though it remained disgusting. He moved forward, stopped, moved back. He went sideways, very, very carefully, extending his hand before him.
He stopped abruptly. He came back, his face angry.
"We were lucky we couldn't use the car," he said when he was near Jill again. "We'd have been killed or worse."
She waited, her eyes frightened.
"The thing that paralyzes men and animals," he told her, "is a projected beam of some sort. We almost ran into it. It's probably akin to radar. I thought they'd put watchers on the highways. They did better. They project this beam. When it blocks a highway, anybody who comes along that highway runs into it. His eyes become blinded by fantastic colored lights, and he hears unbearable noises and feels anguish and they smell what we smelled just now. And he's paralyzed. Such a beam was turned on me yesterday and I was captured. A beam like that on the highway at the lake paralyzed three men who were carried away, and later two others whose car ditched and who stayed paralyzed until the beam was turned off."
"But we only smelled something horrible!" protested Jill.
"You did. I rushed you away. I'd smelled it before. But I went back. And I smelled it, and I crawled forward a little way and I began to see flashes of light and to hear noises and my skin tingled. I pushed my hand ahead of me—and it became paralyzed. Until I pulled it back." Then he said, "Come on."
"What will we do?"
"We change our line of march. If we drove into it or walked into it we'd be paralyzed. It's a tight beam, but there's just a little scatter. Just a little. You might say it leaks at its edges. We'll try to follow alongside until it thins out to nothing or we get where we want to go. Unless," he added, "they've got another beam that crosses it. Then we'll be trapped."
He led the way onward.
They covered four miles of very bad going before Jill showed signs of distress and Lockley halted beside a small, rushing stream. He saw fish in the clear water and tried to improvise a way to catch them. He failed. He said gloomily, "It wouldn't do to catch fish here anyhow. A fire to cook them would show smoke by day and might be seen at night. And whatever's at the Lake might send a terror beam. We'll leave here when you're rested."
He examined the stream. He went up and down its bank. He disappeared around a curve of the stream. Jill waited, at first uneasily, then anxiously.
He came back with his hands full of bracken shoots, their ends tightly curled and their root ends fading almost to white.
"I'm afraid," he observed, "that this is our supper. It'll taste a lot like raw asparagus, which tastes a lot like raw peanuts, and a one-dish meal of it won't stick to your ribs. That's the trouble with eating wild stuff. It's mostly on the order of spinach."
"I'll carry them," said Jill.
She actually looked at him for the first time. Until she found herself anxious because he was out of sight for a long time, she hadn't really regarded him as an individual. He'd been only a person who was helping her because Vale wasn't available. Now she assured herself that Vale would be very grateful to him for aiding her. "I'm rested now," she added.
