This time Harivarman approached the immobile death machine more closely, though still with slow ingrained caution. Now he could see the damage that must have knocked it out. Along one of the machine's flanks, on the side that had been hidden from him earlier, there ran a scar that could only have been inflicted by some powerful weapon. Maculations of molten metal, long ago hardened into slag, rimmed a head-sized hole that stabbed deep into the berserker's body. Small wonder that it was inert.
Straightening from his first inspection of the machine's wound, Harivarman dared to give the tilted headpiece a solid rap with the tool he had in hand. A film of dust, that must have been electrostatically acquired over lifetimes, jumped up to drift in vacuum. Certainly the thing was currently incapable of attacking anyone. There might of course be some last booby-trap built into it somewhere, but that risk the Prince had already decided he must accept.
Then on with the job.
Within a few minutes the Prince was well on the way to setting up his temporary workshop. He already had some lights in place around the dead machine, and had brought in some more tools from the flyer, and had about made up his mind on the best way to begin. It would probably be best first to disconnect the drive unit somehow from the larger portion of the berserker's body, and then move either the drive or the rest of the berserker away into another chamber. If he did that, then the origin of the device he was working on might not be so glaringly obvious. And then, when he brought Lescar out to help him, he might possibly be able to convince Lescar that the hardware they were trying to use was really Dardanian. Lescar's loyalty to his Prince was unshakable, Harivarman had no doubt at all of that; but the Prince also understood that the graying man lived with a monumental fear and loathing of berserkers.
Once he had the necessary minimum of tools and equipment in place, the Prince got to work. It was easy enough to decide to separate the drive unit from the rest. But there was of course the berserker's combat armor to be dealt with. And even here in near-weightlessness the inertia of some of the massive parts was going to make them hard to handle. Of course Harivarman had in the flyer a power-lifter that he could use.
Fortunately, these days even amateur archaeologists were often equipped with high technology. The Prince had an elaborate toolkit already assembled in his flyer. Enough equipment, perhaps, to enable him to get by, at least through the early stages of the job. If he needed more equipment, he could probably invent some convincing story that would let him obtain it.
It was time, he thought, that was going to be his real problem. It seemed certain that he was not going to be allowed the days he needed.
Several hours after his arrival at the site, the Prince had his bubble-workshop inflated. Not in the chamber where he had found the berserker, but in the one adjoining, which fortunately for his plan was connected to the berserker's room by a closable door. Inside his large plastic bubble there hung, almost drifting in the weak gravity, the interstellar drive. Still in its inner casing, it was a massive pod two or three times greater in volume than a man's body, and considerably heavier. Harivarman had tied it to supports in three dimensions to keep it more or less positioned where he wanted it.
Another hour passed. Now that portion of the berserker's control system that seemed to directly concern the drive had been extracted and was already in the process of being spread out for dissection, like some rare and complex biological specimen, on a series of folding boards. The Prince was probing into the control system's electronic nerves with a series of tools, several of which were connected to his flyer's onboard computer. He had had to move the flyer a little closer to the site, wanting to run cables to the computer and not use a wireless link whose signals might conceivably be intercepted.
The Prince's first objective in this examination was to see whether the circuits commanding the interstellar drive unit remained functional at all. The preliminary indications were positive. He had studied berserkers intensely in the past, the better to fight them, and he now had a fair idea of what he was looking for.
And presently he raised his head, sighing. Yes, he could assume now that these control circuits were functional. But how he was going to get them to function under his control was something else again.
Harivarman pushed on with his examination. More time passed, unnoticed by the man who had grown totally absorbed in what he was doing.
But less and less was he thinking of his plan for escape. Eventually an hour had gone by in which the thought of arranging a means of escape from the Fortress had not entered the Prince's mind at all.
He was, instead, making a discovery. The revelation was proceeding only in small steps, but they were steps whose sum was truly breathtaking.
Almost from the start it had been apparent that some very peculiar control information seemed to have been left in the memory banks connected to the interstellar drive of this particular berserker. And Harivarman very soon got the impression, from a certain lack of organization in the way the data was stored, that it might have been left where it was inadvertently. It was chiefly the nature of that information that concerned him now.
Near the beginning of the fourth hour of his investigation, the Prince really paused for the first time. He had to pause. And he had to put down for a while the electronic probe, because his hand was cramped and shaking from gripping it so hard in his excitement. Closing his helmet, resealing the spacesuit that he had been wearing half open inside the shelter, he went out through the shelter's airlock and out of the antique room, its walls almost the same color as those of the Contrat Rouge. In the airless, almost lightless corridor outside the room he paused, clinging to the rough stone wall. In one direction the corridor ran straight for a few hundred meters before coming to an abrupt termination, where some ancient attack, probably by berserkers, had blasted an enormous crater into the outer surface of the Fortress. Looking in that direction, the same direction that was so faintly down, the Prince could see the stars.
Harivarman thought that the discovery he was making, or was on the verge of making, had no parallel in human history.
The original berserkers had been constructed by a race now known only as the Builders, as their last, all-out, desperate bid to win an ancient interstellar war, a war they were fighting against living opponents who were now remembered only as the Red Race. Little information was now available about that war, because it had been fought at about the same time that humanity on Earth was beginning to chip flint and perhaps make arrows. The berserkers' Builders had been arrogant and powerful without a doubt. But they had long since vanished from the stage of Galactic time and space, following the Red Race into oblivion, more than likely victims of their own hideous creations.
The metal war-machines that humans called berserkers were the ultimate enemy of everything that lived. The creators of those inanimate weapons were gone, but the weapons themselves raged on across the Galaxy, endlessly repairing and replicating themselves, improving their own design, and refining their killing capabilities in an eternal effort to accomplish their basic programmed task, the elimination of all life, wherever and whenever they could find it.
Throughout the centuries since Earth-descended humanity had found itself locked in a struggle against the berserkers for survival, human intelligence had postulated and continually sought one great key to victory. Theory held that at least at the beginning of the Builders' ill-starred creative effort, there must have existed some sort of control system by which the Builders could turn the berserkers on and off. A safety code, perhaps. Some means by which the metal monsters could have been handled and tested in reasonable safety by mortal if unearthly flesh and blood.
As far as Harivarman in his earlier studies had discovered, no trace of any such control system or code had ever been found, by Earth-descended humanity or any other living race. Possibly no such code or system had ever existed. If the Earth-descended Dardanians were now a mystery to their cousins who had spread to other worlds, the unknown Builders, eighty or
a hundredfold more distant in time, and not of Earth at all, were that much more difficult to understand.
But it seemed now to Prince Harivarman, with neither his own skepticism nor his computer yet able to fault the truth of his discovery, that the answer to the riddle of the berserker control systems might be within his grasp—one answer to it, anyway. The control sequence that appeared to be revealing itself to him might, he supposed, work for only a certain model of berserker, or perhaps it might work only on machines that had been built in one particular factory or base . . . Harivarman supposed that this piece of hardware before him could hardly be one of the original machines, still largely intact even if not functioning after fifty thousand years or so . . . but he really had no way to judge.
Of course the first question he had to face was whether the controlling code he thought he saw—a relatively simple sequence of radio-frequency signals—was really what it seemed to be. As far as he could tell with the equipment and knowledge he had available, it was. Thank all the gods of space and time, he was not faced with the opportunity for a full practical test.
But if the code was genuine, why should it have been left here? Left here still intact, fifty thousand years after its intended usefulness to the Builders had ended, exposed to the possibility that enemies might someday capture and examine it?
Harivarman couldn't guess why, except that the Builders were demonstrably capable of making gross mistakes. Even colossal blunders. And he knew from experience that even berserkers could sometimes simply malfunction.
As part of his intensive study of the enemy during his years of fighting berserkers, the Prince had taught himself the Builders' ancient language too, or almost as much of it as any living human being knew. That was not much; it included the little that had been picked up from rarely captured records of the Builders and what little more had been deduced from that. The audible form of the language was all clicks and whistles, beyond any Earth-descended throat and vocal apparatus. But the written symbols could be manipulated. And the electronic signals of this code he was now uncovering ought to be easy to reproduce.
Never before, to Harivarman's knowledge, had anything like this seeming control code been found by any human seeker. Had such a discovery ever taken place, it would have been of tremendous importance for all humanity, for all Galactic life, and the news of it must have been spread rapidly. Of course, the only reasonable place to look for such a control code would be in a berserker device that had been captured more or less intact. The Prince knew that the total number of captured intact berserkers in the whole war had been no more than ten or twelve, an amazingly small number considering that the human war against them had raged through thousands of battles, fought across millions of cubic parsecs of the Galaxy, and had dragged on over a span of many centuries. The machines as a rule destroyed themselves when they could fight no more. Or they destroyed at least their own inner secrets. And if the ten or twelve other berserkers known to have been captured had ever carried similar controlling information in their memory banks, they had erased it before they fell into human hands.
But it had not been erased from this one. . . .

Harivarman at length had to force himself to lay down his tools for the day. He had to avoid rousing suspicions of any kind by an unusually prolonged absence from the City. He packed some of his equipment back into his flyer and commanded the machine to take him back into the City. And he was even more thoughtful on this return flight than he had been on the last one. But this time he immediately programmed the flyer to head for his own garage; all thought of announcing his discovery to the Templars had been abandoned for the time being. The realization that he had done this crossed his mind, and he told himself vaguely that he would make that announcement eventually, but in his own way, and in his own good time.
He had left his temporary workshop erected in the distant chamber, with the berserker drive and part of the control system inside it, open to discovery and inspection by anyone who might happen to come along. Doing so would save him time when he came back for the next work session, and time was all-important now. He would just have to risk discovery of his work site. If anyone should stumble on it or seek it out, there would be no doubt anyway as to what sort of work was going on, or who was doing it.
But no one, it appeared, was interested in his remote archaeological research. Harivarman spent the rest of the day unmolested, thinking and resting part of the time, and quietly obtaining a few more tools and materials.

Next morning Beatrix called him early.
"Harry. Am I going to see you? Or did I waste my time and effort completely in coming back here?"
"I . . . you'll see me, I promise you." He was known for not making promises lightly. "But not just yet. I appreciate your coming back."
"Do you? I wonder. I suppose I thought that perhaps at last you would."
He did his best to be brilliantly convincing. They talked a little longer. But what it came down to was that he put off seeing her, as tersely as he could—let her think that he was afraid of being spied on. He put off Lescar, too, by ordering him to remain in the City to gather information.
Harivarman was soon back at his lonely task.
By the end of his second long session of work on the berserker's drive-controlling circuits, the Prince considered that he had done all that was possible, under the conditions, to confirm his discovery. He had actually recorded a version of the basic control signal, and had loaded the recording into a handheld radio transmitter. His next experimental investigations, if he were ever able to conduct them, would necessarily be much more daring.
But it was time now to forsake science and get back to engineering, specifically to the driving necessity for escape. Periodically the Prince's memory, like some nagging robotic secretary, reminded him that any day now, any hour, another ship would arrive at the Fortress, a ship of his enemies, and he would almost certainly be arrested. A rational, conservative part of his mind was starting to argue that he should go to the Templars now, before that happened, go to them this hour, this minute, with what he had discovered.
The rational argument with which he tried to convince himself went like this: No human authority would allow the agent of such a discovery, an achievement of such great and glorious consequence for all life in the Galaxy, to be arrested for some crime committed in a place far from where he was, to be taken away and quietly murdered. But Harivarman had been involved in politics too long to allow mere rational argument to determine his decisions. Maybe the widely beloved Empress had come to believe that she could never be murdered either.
And there was still another reason why Harivarman held stubbornly to his secret. In his mind faint nagging doubts about the truth of his discovery persisted. Those doubts in themselves might have been enough to hold him back from making an announcement. Instinct whispered to him that something was not right, something about what he thought he had discovered . . . maybe it was only because the revelation seemed too perfectly well-timed, coming as it had.
But there it was. The interstellar drive was real and right enough. Not only the control circuits but the whole drive unit was functional, or ought to be, as far as Harivarman's rough tests could tell.
If the Prince was not going to be able to depend on the great value of his discovery to save his life, then escape, using the berserker's drive, appeared to be as much of a necessity as ever. For his third work session on the berserker the Prince brought Lescar out to the job site with him. He told Lescar very little more than he had told him at the start, and showed him only the room in which the innocent-looking drive unit now reposed, and got him started working on it. Lescar's first assigned task was to dissect the control system of the drive further, in preparation for its installation in a different kind of vehicle.
As Harivarman had expected, Lescar's only open reaction to this assignment was to signify his understanding of it and immediately take up a probe and get t
o work. The servant's willingness to take on any task the Prince assigned him was understood by both.
But the Prince was frowning, even as his assistant took his tools energetically in hand. To Harivarman himself, the necessity of explaining some of the technical details of the escape project to a helper, putting the whole idea into plain words, had been enough to make it begin to seem impossible.
And the more fiercely Harivarman tried now to reconvince himself, the more unlikely the whole scheme of using the drive unit began to appear in his thoughts. It was an interstellar drive they were concerned with here, and not the motor of a groundcar. It was even a drive of a largely unfamiliar type.
For a few moments the Prince hovered on the brink of changing his mind suddenly, of telling Lescar to abandon the project and go back to the house and forget what he had seen. But the Prince did not do so. Instinct forbade that too. The trouble was, thought Harivarman, that they had no choice. The more time he had in which to consider the political situation, the more firmly he became convinced that now, with the Empress gone, his enemies were soon going to attempt to finish him off, one way or another.
A day of intensive effort passed, and then another, with the two men working busily—most of the time not really side by side, but just out of each other's sight. Lescar's job in its present stage could rarely benefit from two pairs of hands, and the Prince was still keeping his own work secret even from Lescar. Harivarman labored in the adjoining room, now tracing the paths of control signals through the body and the main brain of the berserker, seeking additional memory banks, looking for more confirmation of his find. The indications that he found were intriguing, but still somewhat ambiguous. A large part of the thing's brain was evidently inaccessible, inside an inner seal of armor impervious to any of the tools he had on hand. In there, if anywhere, he thought, would also be a destructor device, a booby-trap.
