“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.”
