They threshed about, hampered by the bulkiness of the fur clothing. Ross wondered fleetingly why the other had not made sure of him earlier. As it was he fought with all his might to keep Kurt immobile, to try and knock him out with a lucky blow.
In the end Kurt aided his own defeat. When Ross relaxed somewhat, the other pushed against him, only to have Ross flinch to one side. Kurt could not stop himself, and his head cracked against the wheel of the cat. He went limp.
Ross made the most of the next few moments. He brought his belt from under his parka, twisting it around Kurt's wrists with no gentleness. Then he wriggled about, changing places with the unconscious man.
He had no idea of where to go, but he was sure he was going to get away—at the cat's top speed—from that point. And with that in mind and only a limited knowledge of how to manage the machine, Ross started up and turned in a wide circle until he was sure the cat was headed in the opposite direction.
The light which had guided them was still on. Would reversing its process take him back to the base? Lost in the immensity of the frozen wilderness, he made the only choice possible and gunned the cat again.
Once again Ross sat waiting for others to decide his future. He was as outwardly composed as he had been in Judge Rawle's chambers, but inwardly he was far more apprehensive. Out in the wilderness of the polar night he had had no chance for escape. Heading away from Kurt's rendezvous, Ross had run straight into the search party from the base. He had seen in action that mechanical hound that Kurt had said they would put on the fugitive's trail—the thing which would have gone on hunting them until its metal rusted away. Kurt's boasted immunity to that tracker had not been as good as he had believed, though it had won them a start.
Ross did not know just how much it might count in his favor that he had been on his way back, with Kurt a prisoner in the cat. As his waiting hours wore on he began to think it might mean very little indeed. This time there was no show on the wall of his cell, nothing but time to think—too much of that—and no pleasant things to think about.
But he had learned one valuable lesson on that cold expedition. Kelgarries and the others at the base were the most formidable opponents he had ever met, and all the balance of luck and equipment lay on their side of the scales. Ross was now convinced that there could be no escape from this base. He had been impressed by Kurt's preparations, knowing that some of them were far beyond anything he himself could have devised. He did not doubt that Kurt had come here fully prepared with every ingenious device the Russians could supply.
At least Kurt's friends had had a rude welcome when they did arrive at the meeting place. Kelgarries had heard Ross out and then had sent ahead a team. Before Ross's party had reached the base there had been a blast which split the arctic night wide open. And Kurt, conscious by then, had shown his only sign of emotion when he realized what it meant.
The door to Ross's cell room clicked, and he swung his feet to the floor, sitting up on his bunk to face his future. This time he made no attempt to put on an act. He was not in the least sorry he had tried to get away. Had Kurt been on the level, it would have been a bright play. That Kurt was not, was just plain bad luck.
Kelgarries and Ashe entered, and at the sight of Ashe the taut feeling in Ross's middle loosened a bit. The major might come by himself to pass sentence, but he would not bring Ashe along if the sentence was a really harsh one.
"You got off to a bad start here, Murdock." The major sat down on the edge of the wall shelf which doubled as a table. "You're going to have a second chance, so consider yourself lucky. We know you aren't another plant of our enemies, a fact that saves your neck. Do you have anything to add to your story?"
"No, sir." He was not adding that "sir" to curry any favor; it came naturally when one answered Kelgarries.
"But you have some questions?"
Ross met that with the truth. "A lot of them."
"Why don't you ask them?"
Ross smiled thinly, an expression far removed and years older than his bashful boy's grin when playing shy. "A wise guy doesn't spill his ignorance. He uses his eyes and ears and keeps his trap shut—"
"And goes off half cocked as a result . . ." the major added. "I don't think you would have enjoyed the company of Kurt's paymaster."
"I didn't know about him then—not when I left here."
"Yes, and when you discovered the truth, you took steps. Why?" For the first time there was a trace of feeling in the major's voice.
"Because I don't like the set-up on his side of the fence."
"That single fact has saved your neck this time, Murdock. Step out of line once more, and nothing will help you. But just so we won't have to worry about that, suppose you ask a few of those questions."
"How much of what Kurt fed me is the truth?" Ross blurted out. "I mean all the stuff about shooting back in time."
"All of it." The major said it so quietly that it carried complete conviction.
"But why—how—?"
"You have us on the spot, Murdock. Because of your little expedition, we have to tell you more now than we tell any of our men before the final briefing. Listen, and forget all of it except what applies to the job at hand.
"Once Greater Russia emerged from the wreckage of the old Soviet Union and started gobbling up its neighbors, joint space ventures were out of the question. But they didn't start a new space race either. Not that we've sent men to the moon ourselves—" the major's voice tightened "—in more years than I care to count. So why weren't they interested in taking the high ground?"
Ross stared back blankly. Did "high ground" mean space?
"Any discovery in science comes about by steps. It can be traced through those steps by another scientist. But suppose you were confronted by a result which apparently had been produced without any preliminaries. What would you guess had happened?"
Ross stared at the major. Although he didn't see what all this had to do with time-jumping, he sensed that Kelgarries was waiting for a serious answer, that somehow Ross would be judged by his reply.
"Either that the steps were kept strictly secret," he said slowly, "or that the result didn't rightfully belong to the man who said he discovered it."
For the first time the major regarded him with approval. "Suppose this discovery was vital to your life—what would you do?"
"Try to find the source!"
"There you have it! Within the past five years our friends across the way have come up with three such discoveries. One we were able to trace, duplicate, and use, with a few refinements of our own. The other two remain rootless; yet they are linked with the first. We are now attempting to solve that problem, and the time grows late. For some reason, though the Russians now have their super, super gadgets, they are not yet ready to use them. Sometimes the things work, and sometimes they fail. Everything points to the fact that the Russians are now experimenting with discoveries which are not actually their own—"
"Where did they get them? From another world?" Ross's imagination came to life. Had a successful space voyage been kept secret? Had contact been made with another intelligent race?
"In a way it's another world, but the world of time—not space. Seven years ago we got a man out of Moscow. He was almost dead, but he lived long enough to tape some amazing data, so wild it was almost dismissed as the ravings of delirium. But we didn't dare disregard any hints from the other side. So the recording was turned over to our scientists, who proved it had a core of truth.
"Time travel has been written about in fiction; it has been discussed otherwise as an impossibility. Then we discover that the Russians have it working—"
"You mean, they go into the future and bring back machines to use now."
The major shook his head. "Not the future, the past."
Was this an elaborate joke? Somewhat heatedly Ross snapped out the answer to that. "Look, here, I know I haven't your education, but I do know that the farther back you go into history the simpler things are. We ride in cars; only a hundred years ago men drove horses. We have guns; go back a little and you'll find them waving swords and shooting guys with bows and arrows—those that don't wear tin plate on them to stop being punctured—"
"Only they were, after all," commented Ashe. "Look at Agincourt, m'lad, and remember what arrows did to the French knights in armor."
Ross disregarded the interruption. "Anyway," he stuck doggedly to his point—"the farther back you go, the simpler things are. How are the Russians going to find anything in history we can't beat today?"
"That is a point which has baffled us for several years now," the major returned. "Only it is not
how
they are going to find it, but
where
. Because somewhere in the past of this world they have contacted a civilization able to produce weapons and ideas so advanced as to baffle our experts. We have to find that source and either mine it ourselves or close it off. As yet we're still trying to find it."
Ross shook his head. "It must be a long way back. Those guys who discover tombs and dig up old cities—couldn't they give you some hints? Wouldn't a civilization like that have left something we could find today?"
"It depends," Ashe remarked, "upon the type of civilization. The Egyptians built in stone, grandly. They used tools and weapons of copper, bronze, and stone, and they were considerate enough to operate in a dry climate which preserved relics well. The cities of the Fertile Crescent built in mudbrick and used stone, copper, and bronze tools. They also chose a portion of the world where climate was a factor in keeping their memory green.
"The Greeks built in stone, wrote their books, kept their history to bequeath it to their successors, and so did the Romans. And on this side of the ocean the Incas, the Mayas, the unknown races before them, and the Aztecs of Mexico all built in stone and worked in metal. And stone and metal survive. But what if there had been an early people who used plastics and brittle alloys, who had no desire to build permanent buildings, whose tools and artifacts were meant to wear out quickly, perhaps for economic reasons? What would they leave us—considering, perhaps, that an ice age had intervened between their time and ours, with glaciers to grind into dust what little they did possess?
"There is evidence that the poles of our world have changed and that this northern region was once close to being tropical. Any catastrophe violent enough to bring about a switch in the poles of this planet might well have wiped out all traces of a civilization, no matter how superior. We have good reason to believe that such a people must have existed, but we must find them."
"And Ashe is a convert from the skeptics—" the major slipped down from his perch on the wall shelf— "he is an archaeologist, one of your tomb discoverers, and knows what he is talking about. We must do our hunting in time earlier than the first pyramid, earlier than the first group of farmers who settled by the Tigris River. But we have to let the enemy guide us to it. That's where you come in."
"Why me?"
"That is a question which our psychologists are still trying to answer, my young friend. It seems that the majority of the people of several nations linked together in this project have become too civilized. The reactions of most men to given sets of circumstances have become set in such regular patterns that they cannot break that conditioning, or if personal danger forces them to change those patterns, they are afterward so adrift they cannot function at their highest potential. Teach a man to kill, as in war, and then you have to recondition him later.
"But during these same wars we also develop another type. He is the born commando, the secret agent, the expendable man who lives on action. There are not many of this kind, and they are potent weapons. In peacetime that particular collection of emotions, nerve, and skills becomes a menace to the very society he has fought to preserve during a war. In a peaceful environment he becomes a criminal or a misfit.
"The men we send out from here to explore the past are not only given the best training we can possibly supply for them, but they are all of the type once heralded as the frontiersman. History is sentimental about that type—when he is safely dead—but the present finds him difficult to live with. Our time agents are misfits in the modern world because their inherited abilities are born out of season now. They must be young enough and possess a certain brand of intelligence to take the stiff training and to adapt, and they must pass our tests. Do you understand?"
Ross nodded. "You want crooks because they are crooks?"
"No, not because they are crooks, but because they are misfits in their time and place. Don't, I beg of you, Murdock, think that we are operating a penal institution here. You would never have been recruited if you hadn't tested out to suit us. But the man who may be labeled murderer in his own period might rank as a hero in another, an extreme example, but true. When we train a man he not only can survive in the period to which he is sent, but he can also pass as a native born in that era—"
"What about Hardy?"
The major gazed into space. "No operation is foolproof. We have never said that we don't run into trouble or that there is no danger. We have to deal with both natives of different times, and if we are lucky and hit a hot run, with the Russians. They suspect that we are casting about, hunting their trail. They managed to plant Kurt Vogel on us. He had an almost perfect cover and conditioning. Now you have it straight, Murdock. You satisfy our tests, and you'll be given a chance to say yes or no before your first run. If you say no and refuse duty, it means you must become an exile and stay here. No man who has gone through our training can return to normal life; there is too much chance of his being picked up and sweated by the opposition."
"Never?"
The major shrugged. "This may be a long-term operation. We hope not, but there is no way of telling now. You will be in exile until we either find what we want or fail entirely. That is the last card I have to lay on the table." He stretched. "You're slated for training tomorrow. Think it over. Then let us know your answer when the time comes. Meanwhile, you are to be teamed with Ashe, who will see to putting you through the course."
