To his left there was a faint animal-like noise. It sounded like a subdued cackle. An elf or tiny demon pleased with his or her work. There was another small cackle on the other side of him. A third behind Ariel. In a moment there were cackles all around them, and they had become louder. Whatever was inside this building seemed to like chattering to each other.
Taking Ariel’s hand, Derec fled backward toward the door that was faintly outlined from outside daylight. Near the door, before the two of them had flung it open and fled from the building, he nearly tripped over something, something that screeched back angrily at him.
Chapter 4
THE WATCHFUL EYE
THERE WAS NO such thing as an all-seeing eye in Robot City, but the Watchful Eye believed it must come close. Even though it usually sat safe in its haven, its rudimentary body drawn snugly inside, it could observe and examine whatever happened in the city.
Since the time it had arrived in the city through an underground tunnel that had originally been meant for human sewage (of which there had so far been so little that the sewer’s walls were brightly pristine and its clear water smelled fresh and pleasant), it had gradually taken over all Robot City systems.
The Watchful Eye had no idea how it had arrived on the planet. After coming suddenly to awareness in a field outside the city, it had molded itself into simple but functional form. Searching the countryside, it located the sewer tunnel. At first it had transported itself by the kind of carts used for supply and passenger transport through the intricate network of tunnels, and eventually found its way to the lair of the central computer. It had taken a while to learn that the computer was merely a machine and not a living being. It took some more time to discover how to operate it. For one period it roamed at will around the inside of the computer and absorbed random bits of knowledge. Now it had collected a considerable amount of the computer’s information, much of which it was not certain how to use. The only way to find out, it had discovered, was to practice.
First it practiced on the numerous robots that roamed the huge city’s streets. Although it had not yet seen a robot up close, it knew about them from studying the view-screens set up in the underground computer center. As it became more computerlike itself, it began using the computer to communicate with the robots. It convinced the robots that it was human and, according to Second Law, should be obeyed as a human. (As long as they could not see it, the Watchful Eye was able to carry off the illusion convincingly. It had forbidden the highest ranking robots to come into its presence or have any sight of it.)
Although it had accessed much information about humans — visual data, anthropological studies, physiological and anatomical maps, psychological data — it believed it hadn’t yet reached an understanding of what a human really was. It yearned to see one.
There had been no problem in making working models of humans, no difficulty in creating thousands of computer visualizations of human beings. Where it had failed, however, was in really knowing what a human was. All the information files had been entered by humans who already knew what they were. Essential things had been left out, and the Watchful Eye needed to fill in those blanks.
The next step on its agenda had been to study and then obtain control of the city itself. From computer files the Watchful Eye evolved an extensive, albeit distorted, view of the place. Since it had no previous knowledge of humans or robots, it couldn’t always interpret the data it collected. But that didn’t matter. Knowing bits and pieces was enough for the time being. After all, it had learned something about quests and felt that if it continued its Robot City experiments, it could eventually control the place completely. It did not know what it would do when it became that powerful, but it believed that life must, if nothing else, be a learning process. The computer’s philosophical files reinforced that conclusion. When it had power, it would know what to do with it. Once it had not known what a computer was; now it had completely subjugated one. Domination of the city would present little difficulty.
It liked to think of itself as the Watchful Eye because it could keep track of so many parts of the city without moving from its haven. The screens displayed any place it wanted to view, and it could keep track of several points at once. Not that there was much need to oversee the robots. They accepted orders readily and acted upon them with dispatch and without further questions. That was good, because it did not have time to keep specific attention on the individual robots. There was so much to do, so many experiments to conduct, so much to think about....
Eve Silverside walked behind the others, pleased that Wolruf had decided they should walk into the city rather than search out a proper-sized vehicle. Her head often turned to examine the city’s immensity. She had previously seen only the pastoral landscapes of the blackbody planet, with its natural wonders and its robot-made agricultural community. Adam, who had seen a robot city, had described it to her, but she had not been prepared for the overpowering qualities of the real thing. She was now in human form, resembling a chunkier and silver-colored Ariel, and her startlingly humanlike eyes were open wide in amazement.
Even though she had been told about Robot City’s incredible mass of architectural wonders, she had not been prepared for its dazzling array of colors, its intricate walkways, the geometric perfection of its buildings. Although she tended to examine the scene around her with a robotic objectivity, she was impressed and thought Robot City was indeed a splendid place.
Ahead of Eve, Wolruf hunkered down, peered at the edge of a curb, and picked up something.
“What is it, Wolruf!” Mandelbrot asked.
She held up a crumpled piece of paper. Adam took it out of her hand and examined it. “It seems ordinary, not unlike paper I have already seen,” he commented.
“Not that it’ss paperr,” Wolruf said, “it’ss strrange it’ss here at all.”
“I do not understand.”
When Adam talked with Wolruf, his face seemed to change slightly, its human aspects taking on a suggestion of Wolruf’s caninoid features. Adam’s nose seemed to lengthen and his face became flatter, like Wolruf’s.
“Paperr shouldn’t be here, that’ss all. Here on thiss street it iss litterr. Small robotss take care of litterr wheneverr it occurss, which iss rare. Robotss, aft’err all, do not use paperr. The small robotss detect litterr, ‘u see, then collect it, then dispose of it.”
“I see no utility robots in this area,” Mandelbrot said. There were, in fact, no robots of any kind to be seen. “Perhaps one will come soon.”
“Maybe,” Wolruf said, then loped a few steps farther and pointed at the pavement. “Thiss iss slidewalk,” she said.
“Yes,” Mandelbrot said.
“Shouldn’t it move? We stand on it, it remainss still when ourr body weight should make it move.”
“That is truly puzzling. Perhaps it is inoperative.”
“If so, where are Slidewalk Maintenance Robotss? When something in city breakss down, maintenance robotss are ssupposed to appearr immediately.”
“Perhaps they are busy elsewhere with a different slidewalk.”
“Maybe. But thingss don’t break down in Robot City at such rate. Two areass of slidewalk down at same time in same sector iss unusual, ‘u see.”
“Yes. I should inform you also of another matter.”
“What, Mandelbrot?”
“Since you have been observing these flaws, I have been trying to contact other robots through my comlink to obtain answers for your questions, and so far none have responded. Based on data from my previous visits to this city, such a phenomenon, even on the outskirts here, is highly anomalous.”
“‘U believe ssomething iss wrrong here, Mandelbrot?”
“Yes, I do.”
“Let’ss go on then.”
Eve wasn’t sure what to make of the conversation between the caninoid and the robot with the strange arm, itself something of an anomaly. The arm, which had once belonged to a robot of a different class than Mandelbrot, was
shaped differently and, because it was thicker and longer than his other arm, looked awkward on his body. It was malleable and Mandelbrot could change its shape, although, unlike the Silversides, he could not transform any other part of his body.
Thinking of her shape-changing ability seemed to start up a mechanism in her body. She looked around for something to change into. Adam had explained to her that there seemed to be an urge inside them to seek out new beings and imprint upon them. It was very humanlike, he said, or at least Derec had informed him so. “Derec says that humans love to seek out new experience. A new experience for us is a previously unseen kind of being whose shape we can take. Although we are not supposed to have emotions about it, I think the mechanisms inside our bodies are engaged when we think about changing ourselves or when we see a being on which we can imprint.” Whatever it was, a simple mechanism or a genuine yearning for new experience, Eve now felt a strong urge to form herself into a new shape.
But what shape could she choose? She had been human like Ariel, caninoid like Wolruf, a robot like Mandelbrot.
There must be some different kind of life here, she thought. She walked closer to a building, a strange structure, narrow and tall. Staring up at its top, she saw a row of ugly birdlike creatures staring down at her from under the building’s eaves. They were still, impassive, although she thought she perceived a meanness in their eyes. Stepping back to try to see them better, she pointed upward and asked Mandelbrot, “What are those, please?”
Mandelbrot glanced up at them. “They are not alive,” he said. “They are some kind of ornament placed along the upper rim of the building. I think they are called gargoyles. These are made of Robot City material, but in the past they have often been sculpted from stone.”
“They are interesting. Adam? Do you think we could become like that?”
Adam had adopted a quite humanlike shrug, copied accurately from Derec. “We could become statues, yes, but I see no point in it. There is little for us to learn from representations of life, Eve, unless we actually encounter the creatures that were the models for these statues.”
“I doubt that that would be a pleasant experience,” Eve said. She looked away from the gargoyles and walked a few steps farther, then she turned and went back.
There was something here, inside this building, and it was not gargoyles. She sensed there was something on the other side of the wall, just standing still but perhaps with life inside it.
“Mandelbrot?”
“Yes, Eve?”
“How does one gain entrance to such a building as this?”
Mandelbrot had been instructed by Derec to cooperate with the Silversides as much as possible unless he sensed danger for them. There did not seem to be any threats hereabout, so he replied, “I believe the door for this building is located on the north side. Up those steps.”
Eve immediately went up the steps. Climbing was one of the few activities that made her appear more robotlike than humanlike. There was a certain mechanical awkwardness to the way she proceeded from stair to stair.
At the top of the stairs, there was indeed a door, and it was slightly ajar. From below, Mandelbrot saw the door hanging open and cautioned, “The open door. That is another anomaly. Do not go in there, Eve.”
One thing that Eve had “inherited” from copying Ariel was stubbornness. Once she had a goal set in her mind, she would not easily veer from it. She pushed the door open and went inside.
With a faint crackle, some light came on. To Eve it was clear that the illumination was not full power. That didn’t matter to her; she increased the power of her optical sensors. The room was dim, and there were many shadowy areas. She increased her olfactory sensors and observed that the hint of an unpleasant odor in the room was more than just a hint. There was a heavy pervading sense of decay in it. Something might be dead in here.
The room was cluttered. Broken glass littered the floor (she recalled what Wolruf had said about utility robots keeping things clean); some furniture had been heaped in one corner, most of it with missing pieces or chunks; metal debris was all over the room in piles of varying sizes; everything was laden with dust.
She walked through the room boldly, scrutinizing its contents. Behind her, Mandelbrot came through the doorway.
“Eve, Derec has instructed me to keep you and Adam away from harm. We don’t know anything about this building, so please come with —”
“What is this, Mandelbrot?” She held up what appeared to be a long jointed tube made of metal wires and strips, plus some electronic wiring.
“I would say part of the skeleton of a robotic limb. Well-articulated if complete. Now, Eve —”
“There’s something over here.”
As she neared a shadowy niche, she saw that there was someone in it. However, she could detect no life coming from the figure. Even though it was standing, its legs were crossed unnaturally. There were shreds of cloth remaining from an outfit that was not definable. Its torso seemed ravaged and scarred. Its eyes were so deepset that at first she wasn’t sure there were any. There were black circles around them. Its arms hung at odd angles.
“Mandelbrot, this looks like a —”
As she came close, the figure’s head moved slightly as if about to slide onto its left shoulder, and it reached out its left arm toward Eve. She was tempted to ignore Mandelbrot’s warnings to back away from it and instead take the hand.
The Watchful Eye had detected Robot City’s new arrivals and was quite gleefully keeping track of them. They might be human, it thought. The first two it saw on its view-screens answered many of the requirements it had deduced for humans, requirements that it had laboriously formulated from the visual and technical information in the many computer files. Still, its uncertainty as to what actually constituted a human made it want to continue observation at a distance.
The Watchful Eye had a need to know about humans. So far it had been frustrated in its studies and experiments by the lack of any genuine humans to observe. Now perhaps they had returned to the city apparently built for them.
Listening in on their conversation, it detected that the new arrivals’ names were Ariel and Derec. There was a lot of data about a Derec in the files. This might be he. Derec had been so important he had one of the access codes to the computer. It had been extremely difficult for the Watchful Eye to bypass and then cancel it.
After Derec and Ariel had entered the warehouse where some of the Watchful Eye’s failures (Series B, Batch 29) were housed and had been attacked by the cackling monstrosities, it became confused. The humans, if they were indeed humans, just ran away, out to the street. Why did they run? What kind of emotional weakness could cause such cowardice? Maybe they were not humans, then; maybe they were failed entities, just like its own creations.
It didn’t have much time to consider their behavior because it detected another set of intruders. First he saw the small furry being who was so assiduously examining whatever she found in her path. Her intelligence was clear, and she was observant. It listened in on her comments about the litter she had found. That was perceptive of her, observing that discarded paper was a rare thing in the city and that utility robots should have removed it long ago. It was not sure where the paper had originated, but it suspected that it came from one of its experimental creations in the building that Eve had inspected. It recalled that the place was a warehouse for some more of its abandoned experiments. There had been some ritual among these creations that had involved paper. It had not liked the ritual, in which strange-looking marks were made on paper, and so had forgotten it. As far as the litter problem went, perhaps it would reactivate the robots that had once had that job.
Next in line was clearly a robot, but even the robot was a variation on what it was used to. Mandelbrot, as it heard the robot called by the fur-creature, whose name was apparently Wolruf, had an arm that did not seem to belong on his body.
The figures following Mandelbrot confused the Watchful Eye, who was not easily
disturbed. It recognized right away that they resembled the two humans it had seen earlier. They had similar faces and bodies, but their skin was a sort of silvery blue as compared with the faint pink tone of the earlier arrivals, and there was a bit more rigidity in their movements. Otherwise, they could have been twins of the pink beings. Further, there was assurance in their walks and the way their arms swung calmly at their sides.
It had a new problem to consider now, one that increased its interest. Both sets of intruders resembled humans as described in computer files. The first set seemed more awkward and not as self-assured as the second set. However, the second duo, who had the proper bearing and look of intelligence, were, in coloring, more like the city’s robots. Its first impression was that while both sets could be human, the second might be an advanced version of the species.
When Eve entered the warehouse, it was very pleased. It found that a circuit inside one of its creations there was still operable (though very weak), and it was able to make it move by remote control. It liked Eve’s cool response to the event. She seemed much more in command of her emotions than the skittish pair who had entered the other warehouse then scampered out of it at their first opportunity. If the Watchful Eye could have smiled (and it could have but had never bothered to learn the manipulation for the physical display of amusement), it would have smiled with satisfaction at what it now perceived as the superior human, Eve Silverside.
Chapter 5
TIMESTEP AND BOGIE
AS THE WAREHOUSE door slowly and creakily shut, Derec thought he saw many eyes looking back at him from the closing sliver illuminated by daylight. Even after the door was closed, he still felt there was a good chance he would see the eyes again in his next nightmare.
Ariel, now relaxed in his arms, snuggled her head against the side of his neck. Since she was a bit taller than he, she had to slouch awkwardly in order to perform the act.
