Alvar Kresh looked down at his desk and found his thoughts turning toward the routine business of running the department. Personnel reports. Equipment requisitions. The dull humdrum of bureaucracy seemed downright attractive after the chaos of the last few days. Best get to it. “That’s all for now, Donald.”
“Sir, before I go, there is one more datum of which you need to be apprised.”
“What is that, Donald?”
“The blow to Fredda Leving, s head, sir. The forensic lab has established that Caliban almost certainly did not do it.”
“What?”
“It is another part of the new patterns of evidence, sir. There were traces of red paint found in the wound, sir.”
“Yes, I know that. What of it?”
“It was fresh paint, sir, not yet fully dry. Furthermore, according to the design specifications for Caliban’s body type, a given robot’s color is integral to the exterior body panels. With that model robot body, dyes are blended into material used to form the panels. The panels are never painted. The body material is designed to resist stains, dyes, and paints. In short, nothing will stick to that material, which is why it must be imbued with a color during manufacture.”
“So that paint couldn’t have just flaked off Caliban’s arm.”
“No, sir. Therefore, someone else, presumably with the intent of framing Caliban, painted a robot arm red and struck Leving with it. I would further presume that person to be unknowledgeable concerning the manufacture of robot bodies, though that presents difficulties, as everything else suggests that the attacker knew quite a bit about robotics.”
“Unless the red paint was, if you’ll pardon the expression, a deliberate red herring.” Alvar thought for a moment. “It could still be Caliban, or someone else, who knew about the color process for that robot model. Caliban could have painted his red arm red merely to confuse the trail. He would know we would find out about the color issue, and therefore would know we’d think he could not have done it.”
“You are presupposing a great deal of knowledge and cunning for Caliban, especially considering that you suggested a minute ago that he did not know what a human being was.”
“Mmmph. The trouble with you, Donald, is that you keep me too honest. All right, then. If Caliban did not do it – then who the damned hell-devils did?”
“As to that, sir, I could not offer an opinion.”
Caliban came to another tunnel intersection and hesitated for a moment before deciding which way to go. He had yet to see a single human in the underground city, but it seemed unwise to be in the company of robots, either. There seemed to be less traffic on the left-hand tunnel branch, and so he went that way.
There had been moments, more than a few of them, since his awakening, when Caliban had experienced something very like the emotion of loneliness, but he certainly had no desire for companionship at the moment. Right now he needed to get away, to put as much distance and as many twists and turns as possible between himself and his pursuers. Then he needed to sit down somewhere and think.
The robots here underground were quite different from those he had seen on the surface. No personal-service robots down here, no fetchers and carriers of parcels. These passages were populated by burlier sorts, lumbering heavy-duty machines in dun colors. They had little resemblance to the brightly colored machines overhead. Compared to these robots, the ones above were merely toys. These underground robots were closer kin to the maintenance units that toiled on the surface only by night. By night, and underground, do the true workers toil, Caliban thought to himself. There was something disturbing about the thought, the image.
He was coming to understand that this was a world where real labor, work that accomplished something, was distasteful, something that had to be done out of sight. The humans seemed contemptuous of the very idea of work. They had taught themselves it was not a proper thing to see, let alone do. How could they live, knowing themselves to be useless, pampered drones? Could they truly live that way? But if they allowed themselves to be waited on hand and foot, then surely they must, as individuals, and as a people, be losing even the ability to do most things for themselves. No, it could not be. They could not possibly be making themselves so helpless, so vulnerable, so dependent on their own slaves.
The ways under the central part of the city were clean, dry, and bright, bustling with activity, robots going off on their errands in all directions. None of that suited Caliban’s purposes. He consulted his on-board map and headed toward the outskirts of the system.
The main tunnels and the older tunnels were lit in frequencies visible to humans, Caliban noticed. Perhaps that was some sort of holdover from the days when humans had trod these ways. The newer ones were lit in infrared, offering mute testimony to the absence of human use in these latter days.
Caliban moved farther and farther, out into the outskirts of the system, where even the infrared lighting got worse and worse. Infrared lights were supposed to come on as he approached, and cut off as he left, but fewer and fewer of the sensors seemed to be working. At last he was walking in complete darkness. Caliban powered up his on-board infrared light source and found his way forward that way.
The condition of the tunnels was deteriorating as well. Here, well out from the center of town, most of the tunnels were semi-abandoned, cold, dank, damp, and grimy. Perhaps the surface of Inferno was bone-dry, but clearly there was still deep groundwater to be found. Tiny rivulets of water ran here and there. The walls sweated, and drips of water came down from the ceiling, their splashing impacts on the walkway echoing loudly in the surrounding silence. Out here, on the perimeter, only a few lowly robots ventured, scuttling through the darkness, intent on their errands, paying Caliban no heed.
Caliban turned again, and again, down the tunnels, each time turning in the direction with the least traffic. At last he walked fully in the dark, fully alone. He came to a tunnel with a glassed-in room set into one side of it, a supervisor’s office, from back in the days when there was enough work of whatever sort had gone on here to justify such things. Or at least back in the days when they could imagine a future with an expanding city that would need a supervisor’s office out here.
There was a handle on the door, and Caliban pulled at it. He was not oversurprised to find that the door was jammed shut. He pulled harder and the whole door peeled away, hinges and all. He let the thing drop on the ground with the rest of the debris and went inside. There was a desk and a chair, both covered with the same moldering grit that seemed to be everywhere in the unused tunnels. Caliban sat down at the chair, put his hands flat on the desk, and stared straight ahead. He cut the power to his infrared light source and sat in the featureless blackness.
No glimmer of light at all. What a strange sensation. Not blindness, for he was seeing all that could be seen. It was simply that what he was seeing was nothing at all. Blackness, silence, with only the far-off echo of an intermittent water drip to stimulate his senses. Here, certainly, he would hear any pursuit echoing down the tunnels long before it arrived, see any glimmer of the visible or infrared light his pursuers would have to carry. For the moment, at least, he was safe.
But certainly he was not so for the long term. What was it all about? Why were they all trying to catch him, trying to kill him? Who were they all? Was it all humans everywhere that were pursuing him? No, that could not be. There had been too many people on the street who had done nothing to stop him.
It was not until he had dealt with that one man with the packages that things had spiraled out of control. Either he, Caliban, had done something that inspired the man to call in the uniformed people, or else that particular man was in league with the uniformed group, ready to call for them if he spotted Caliban. Except the man had not seemed to show any interest or alarm at first, and did not act as if he recognized Caliban. It was something about the way he, Caliban, had acted that had made the man upset. Some action of his set off the reaction of the man and the mysterious and alarm
ing uniformed people.
Who were they, anyway? He brought up a series of images of them, and of their uniforms and vehicles and equipment. The words Sheriff and Deputy appeared several times on all of them. The moment his mind focused on the words, his on-board datastore brought up their definitions. The concept of peace officers acting for the state and the people to enforce the laws and protect the community swept into his consciousness.
Some of the mystery, at least, faded away. Clearly these sheriff’s deputies were after him because they believed he had violated one law or another. It was of some help to get at least that much clear, but it was extremely depressing to realize that it was all but certain that the Sheriff would continue to hunt for him. The other group, the ones who had called themselves Settlers, had not continued to pursue him after their first encounter.
Were they, the Settlers, in any way connected with the deputies? There was nothing in his datastore that could tell him either way. And yet there was something furtive, something secret about the Settlers’ actions. And they were, after all, engaged in the destruction of robots, which did seem to be an offense under the criminal code. It had to have been the deputies that they were hiding from. Was it illegal to be a Settler? Wait a moment. There was a side reference to criminal organizations, and the Settlers were not in it. At least that told him something about what they were not. It was enough to conclude, at least tentatively, that the group in the warehouse was some sort of criminal offshoot of the Settlers.
Which still told Caliban nothing about them except that they wished to destroy robots generally and himself specifically.
But wait a moment. Back up a little. If destroying a robot was a crime –
With a sudden shock of understanding, Caliban recalled his own first moments of consciousness.
His arm outstretched before him, raised as if to strike. The unconscious woman at his feet, her life’s blood pooling around her...
The sheriff’s deputies dealt not in certainties, but in probabilities. They worked with evidence, not with proof.
And there was a profusion of evidence to suggest that he had attacked that woman. The possible charges spewed forth from his datastore. Aggravated assault. Attack with intent to murder. Denial of civil rights by inducing unconsciousness or death. Had she been dying when he had left her? Did she indeed die? He did not know.
With a shock, Caliban realized he had absolutely no objective reason to think that he had not attacked her. His memory simply did not stretch back before that moment of awakening. He could have done anything in the time before and not know about it.
But that did not address the issue of the police who were in pursuit of him. It seemed obvious they were chasing him because of the attack, but how did they connect him to the crime? How did they know? With a sudden flash of understanding, he remembered the pool of blood on the floor. He must have walked through it and then tracked it out the door. The police, the deputies, had merely to look at those prints to know they belonged to a robot.
Staring into the darkness, he looked back into his own past. His robotic memory was clear, absolute, and perfect. With a mere effort of will, he could be a spectator at all the events of his own past, seeing and hearing everything, and yet aware of being outside events, with the ability to stop the flow of sights and sounds, focus on this moment, that image.
He went back to the very moment of his awakening and played events forward for himself. Yes, there was the pool of blood, there was his foot about to go down into it. Caliban watched the playback with a certain satisfaction, congratulating himself on figuring out how the police had done it.
But then, with a sense of utter shock, Caliban saw something else in his memory. Something that had most definitely not registered when this sight had been reality, and not merely its echo.
Another set of footprints leading through the room, out a door he had not used. Footprints he had no recollection of making, and yet the pattern of the marks on the floor would seem to match his own. But how could that be? Caliban snapped out of his reverie, powered up his on-board light source again, stood up, and went back into the tunnel. He had to know for certain. He found a pool of water, splashed around in it, and then walked out of the puddle onto dry floor. He turned around and examined the resulting prints.
They were identical with the prints he had seen in his memory of his awakening. The bloody footprints were the twins of the watery ones he had just trod across the grimy floor.
They were his own. He must have made them, or else the world made even less sense than he thought it did.
But why would he have done it all? Why would he smash down his arm on the woman’s skull, tread through her life’s blood, form a set of prints, go out one door, clean his feet (for there were no prints leading back into the room), then return to his position over the body, raise his arm – and then lose his memory? And how could he lose his memory that cleanly, that completely? How could there be no residual hint of those past actions left in his mind? In short, how could being alive have left no mark on him?
Caliban could feel himself growing more sophisticated, more experienced, with every moment he was alive. It was not merely a question of conscious memory – it was understanding. understanding of how the city fit together, understanding that humans were different from robots.
It was knowledge of the world, not merely as a series of downloaded reports of rote fact, but the knowledge of experience, the knowing of the details of sensation. No datastore map would ever report puddles in the tunnel, or the echoing sounds of his footsteps down a long, empty, gritty walkway, or the way the world seemed a different place, and yet the same, when viewed through infrared. He turned and walked back down the corridor to the abandoned office and resumed his previous seat, powering down his infrared again to sit in the pitch-blackness. He felt that his train of thought was worth pursuing. He considered further.
There were things in the world, like the strange way seeing the darkness was distinct from blindness, that had to be experienced firsthand to be understood.
And he knew, utterly knew, that he had no such sophisticated experience when he woke up. None, not a flickering moment of it. He had literally awakened to a whole new world. He had come into memory with no firsthand experience.
The first thing he had done was to kneel down and stick his fingers in the woman’s blood, feel its warmth on his skin thermocouple, test his blood-covered finger and thumb against each other to confirm that drying blood was sticky. That moment, he was certain, was his first. There was nothing else before it.
Which either meant that he had not even been awake before his memory started, or else that everything had been wiped from his brain.
A disturbing thought, but Caliban considered it carefully. He had no knowledge of how his mind worked, or how, precisely, it related to his physical being. Beyond question, they were related to each other, and yet clearly distinct and separate. But how, he was not sure.
Once again, he was up against the desperately frustrating absence of any knowledge of robots in his datastore. He had no way of judging the mechanics of the idea, no way to know if there was some way simply to hit an erase button and destroy his mentality.
But if that had happened, if his mind and his memory had been destroyed so completely that even the sense of experience was gone, then could it even be said he was the same being as before?
Memory could be external to the sense of self. Caliban was sure of that. His memories could be removed, and he would still be himself, just as much as he would be if his datastore was removed. But if someone removed all experiential data from his brain, they would of necessity remove the being, the self, who had been shaped by those experiences. Erase his mind, and he would simply cease to be. His body, his physical self, would still be there. But it was not this body that made him Caliban. If it were mechanically possible to remove his brain from this body and place it in another, he would still be himself, albeit in a new body.
And there
fore, he, Caliban, had not attacked this woman. Of that much he was sure. Perhaps his body had done it, but if so, another mind than the one that currently inhabited it was in control at the time.
He found that conclusion to be most comforting, in its own way. The idea that he could be capable of an unprovoked attack had been most disturbing. Still, no matter what his conclusions might be to himself, they did little to improve his situation. Peace officers willing to use heavy weapons in a tunnel would be unlikely to wait long enough to listen to his explanation that it might have been his body, but not he himself, that had attacked the woman. Nor would any such arguments make them forget the fire at the warehouse. He had been there, the place had caught fire. Perhaps that was all they needed to know.
From the police point of view, all the evidence shouted out that he had attacked the woman, that he set fire to that building. After all, the police knew someone had attacked her. If he had not, then who had? As best he could see, there was no one else there who could have done it.
But perhaps there were more things in his visual memories of his awakening, other things that he had missed. The woman, for example. Who was she?
Sitting in the darkness, he once again brought the scene up before his eyes. Now he did not try merely to play back the events, but instead worked to build up as full and complete an image of the room as he could, using all the angles, running through all the images over and over again at high speed, trying to assemble as much detail as possible using all the momentary images at his disposal.
In the darkness, in his mind’s eye, he effectively made the room whole and then stepped into it, projecting the image of his own body into the imaginary reconstruction of the room. He knew that it was all illusion, but a useful illusion for all of that.
Yet it was flawed, deeply so. He turned around to look at the back of the room, and it was not there. He had not ever looked in that direction in real life. The jumble of objects sitting on this table or that looked real enough when he looked at them from the angles he had used in reality, but as he moved his viewpoint to other angles, that he had not used in reality, they melted into a bizarre mishmash of impossible shapes and angles. It was all most disturbing. Perhaps with further effort, he could refine the image, make reasonable educated guesses that could clear up such difficulties. But now was not the time.
