Suspicion

Chapter 3. The Extruder

Derec rode the aqueduct like a log in a sluice, his body numb, his senses and his fate out of control. The waters raged in his ears as his entire existence turned on the simple act of trying to keep his head above water. Nothing else mattered; life had reduced itself to its essence. There was no fear, no time for it, and any yearnings to have his life pass before his eyes went unsatisfied, since he had no life to reflect upon. There was only the water and the numbing cold-and the ubiquitous companionship of Death.

His ride could have lasted a minute or an eternity-he was beyond calculating time-but when he felt himself free-falling in midair, his brain snapped to the new reality and questioned.

He was falling, surrounded by a hot, moist wind. A bare glow of light seemed to envelope him, but before he had a chance to appreciate it, he splashed into hot water.

He had gulped down water with his quickly sucked breath, and when he bobbed to the surface like a cork, he was choking and coughing, his head pounding with a heartbeat throb. He panicked, then forced himself into control when he realized the water he was in wasn’t flowing, but pooling.

As he treaded water, he found himself grateful to his former life for giving him the lifesaving advantage of swimming lessons. He leaned back and floated on his back, small currents pulling him this way and that. His body ached horribly from the battering he had taken in the aqueduct; every bit of strength had drained from him.

There was a ceiling of some sort above him, tiny lights making it dimly visible. The roar of waterfalls filled the hollow cavern completely, and he turned his head to the side to get a glimpse of his surroundings.

He was a hundred meters from the edge of a large square pool that stretched perhaps a thousand meters across. Red lights set at regular intervals bathed the entire area in an eerie glow. In the middle of each side of the pool were aqueduct runoffs, four in all, their cascades shimmering like fading pulsars in the red haze. These four runoffs provided the incredible noise that churned inside his head, all of it echoing within the confined space.

Where was he? A collection point of some kind, perhaps a reservoir. Any city needed a water supply. This was probably connected to a water treatment plant meant to sustain the human population that didn’t live there. This only strengthened Derec’s earlier speculation that this was not a city simply meant for robots. What was going on here was serious colonization.

Another realization occurred to him, too. The reservoir had saved his life. He had been showing the beginning signs of hypothermia during his wild ride down the aqueduct, but the hot water of the reservoir was thawing him out.

Why hot water? The water was definitely warmer than human body temperature, perhaps as much as fifteen degrees, and incredibly hot winds were raging through the chamber, competing with the charging runoff waters in loudness. In fact, the soothing heat and the rest were already beginning to lull his senses, and he realized that if he wasn’t careful, he could end up at the other end of the physical spectrum with hyperthermia. Whether hypo or hyper, though, the results were still the same. He was going to have to get out of the water or risk overburdening his heart.

Still on his back, he churned his legs lightly while propelling himself with his arms. There seemed to be robotic movement at the far end of the reservoir, but he didn’t have the strength to swim that far. Having no idea of which way to go, he simply moved toward the closest shoreline. The process was time-consuming, though, for the runoffs created their own currents.

He swam with leisure, but determination, taking the time to check out his body. He had taken a beating in his wild ride down the aqueduct, but besides general bruises, nothing major seemed to be wrong.

As he neared the edge of the pool, he could see that the runoff streams had slowed considerably, leading him to speculate that the rain had stopped outside. Fuzzy light was also beginning to seep in around the dark edges of the covered pool, and he realized that day had broken.

He finally reached the edge of the pool, its surface made from the same material as the rest of the city. Metal ladders were set at regular intervals around the edge, and he floated to the nearest one to begin his climb out.

The water was barely three meters from the top of the pool, and fortunately so, because as soon as Derec began his climb he knew he wasn’t doing well. His body, so light in the water, felt like it weighed a ton. The combination of emotional stress, the ordeal of the aqueduct, and the overheated water of the pool had all had an effect on his body. He dragged himself slowly up the ladder, then rolled, gasping, onto the edge of the pool and lay there.

He closed his eyes, just for a minute, and he was gone. He didn’t know how long he had slept, but when he awoke, it was with a start. A loud rumble assailed his hearing. He sat up quickly, darting his head around, and saw a large vehicle moving around the pool toward him, its engine noises amplified to a roar in the cavern-like surroundings.

Standing was a problem, since Derec still felt weak. But he got up on shaky legs and moved toward the areas of light beyond the reservoir. While he was still out and on the loose, he wanted to see as much as he could. For, this time, the robots wouldn’t be so quick to let him out of their sight.

As he moved toward the light, he passed open caverns that were filled with conduits for moving water. The huge pipes were twisted like knotted rope and seemed to be moving, writhing, like a snake pit-almost as if they were alive. He was taken over these areas by railed walkways that simply extended from the edges of the pit at his approach, growing-like crystals-before his eyes.

After the pits, he passed several squat buildings where he surmised the actual water treatment was performed. Drone robots moved in and out of the facilities rapidly, mostly moving machinery in both directions. Derec briefly considered going into one of the structures to search for a terminal, but the still-approaching vehicle made him change his mind.

“HUMAN!” came a loudspeakered voice. “YOU WILL HALT YOUR PROGRESS WHERE YOU ARE. IT IS UNLAWFUL FOR YOU TO PROCEED.”

He turned to the sound. It was coming from the robot-controlled vehicle that was rapidly closing the distance on him. It was time to move!

He ran past the building toward glowing walls of light just beyond.

“HUMAN!” the loudspeaker called again.

He raced to the wall, his legs heavy. The entire wall seemed lit and wrapped a circle around the reservoir area. It was translucent, like a shower curtain, and he realized that it was simply so thin that outside light passed right through. He pushed on it, but it felt solid. He pushed harder, and it gave under his hand, just like the wall last night.

Just then, he saw a drone approach the wall twenty meters distant and move right through it. He hurried there, with the robots in the vehicle closing rapidly on him. He stood at the spot, seeing no entry, but when he raised his hands to push against it, the wall irised open and he stepped through into the daylight.

It was morning, bright and calm, with no sign of the deluge that had taken place the previous night. The sun was still low in the sky, but Robot City was alive and active.

He was in the very heart of it here, the hub upon which the wheel of the city turned. He could see the aqueduct that had brought him cutting through the city like a spoke, and he could see other aqueducts, other spokes, slicing through the wheel of the city. And he began to think of the areas between the spokes as quadrants.

Robots in large numbers hurried quickly through the streets, always going somewhere, always busy with predetermined tasks. Many of them were disappearing into the treatment plant.

He moved a small distance from his exit point, then looked back at the reservoir, shocked to find a forest there! Then he realized that the forest had been planted above the reservoir, the land area serving double duty. But why a forest? Not for robots, certainly.

Out of the corner of his eye, he noticed the large, wheeled vehicle that had been tracking him within the reservoir moving through the exit point to the outside. He looked back at the city, then up at the forest. He would find escape in its random chaos.

Angling himself away from his pursuers, he ran back toward the huge reservoir building, preparing to climb one of the struts that helped support the outside edge of the forest. But as soon as he reached the place and put his hands on the arched strut, it seemed to melt away, changing into a gently sloping stairway.

He hurried up the stairs without a question and entered the forest. The ground was moist and spongy, muddying his already-soaked shoes. The trees were small, in many cases smaller than the underbrush that grew thick around them. A haze seemed to fill the entire forest, and the farther he plunged into it, the hazier it became.

Derec was no expert in vegetation, but he assumed the trees were all offspring, many generations removed, of trees that had once grown on Earth. Spacers, though hating to mention any connection to the planet of their ancestry, nevertheless made it a point to bring Earth vegetation and animal life to whatever planet they colonized. Where he’ gotten such information, he had no idea; the small glimpses of his own mind were maddening in their incompleteness.

He wandered the forest, pushing through the haze and the dense undergrowth, feeling jittery in untamed surroundings. And he knew that these were also the feelings of a Spacer pushing through his mind. He didn’t much like the forest; he longed for the order of the city. But for a human being, this had its place. Untamed but finite, aesthetically pleasing without being uncontrollable. This place existed for the aesthetics-for human aesthetics.

His foot hit something hard and uncompromising, and he tripped, going hard to soft ground, getting mud all over himself. He turned to the object that had caused his fall and found a small section of pipe sticking out of the ground. A fog-like haze was pumping from the pipe, the same haze that filled the entire area, and Derec began to see a master plan at work here.

He stood, then ducked when he saw a shadow moving through the haze not five meters from him. It was one of the robots. He listened and could hear them thrashing through the brush all around. They were slowly cordoning off the entire area, boxing him in.

He took a deep breath, then scrunched up into a ball and lay on the ground, listening as they moved near him. The forest was built over the reservoir so that condensing water could feed up to the trees from beneath and nourish the roots directly. Further, the haze was probably carbon dioxide vapor feeding the forest to promote health and growth. Where did the CO2come from? Perhaps a bleed-off from their industrial processes, which could also explain the heat in the reservoir area. The set-up was sophisticated and civilized, a city built around its ecological needs. Was it all of robot design?

A metal foot clanked down just an arm’s reach away from his position. He stifled the urge to rise up for a breath of normal air. Within seconds, the robot moved on.

As he heard the search party sweep past, he jumped to his feet and charged back in the direction he had come. The robots were much faster and stronger than he was, so he was going to have to make things happen quickly at this point.

He reached the edge of the forest in minutes, and rushed to the place where he had climbed up. The strut was already solid again, the steps nowhere to be seen. He looked over the edge of the forest. It was ten meters to the ground; jumping was out of the question.

“You, Derec!” came a robot voice behind. “Stop now! Stop!”

He sat on the ground and dangled his legs over the edge of the strut. Steps miraculously formed again. He ran down just as several robots reached the edge of the forest, calling for him to stop.

Amidst the confusion near the water treatment facility, he saw a large flatbed vehicle, filled with what looked like broken computers, ready to pull out. He took the last steps in leaps and charged the machine, the robots behind already reaching the bottom of the stairs.

The truck pulled out before he reached it, but with a burst of speed, he caught it and jumped into the back. A small, round drone the size of his head squeaked at him from among the broken computers.

Katherine stood at the wash basin, watching the lukewarm water flow from the tap, and wondered how plumbing could possibly be accomplished in a city that didn’t stand still. She splashed her face with water, then stared into the small mirror that was inset above the basin. Her eyes were puffy and dark, showing the results of no sleep, but her face remained calm, remarkably calm considering the terror that had been flashing through her for most of the long night.

He was gone, perhaps dead, and she was alone on this crazy world. Though David/Derec, whatever he wanted to call himself, had never looked on this place as anything but an adventure, to her it had been nothing but a prison. A first priority for anyone marooned in a Spacer port would be access to radio communications to inform search parties and anxious waiters; yet the robots seemed reluctant-no, evasive-when it came to the topic of communications. That frightened her more than anything else that was going on.

“Did you sleep well?”

She jumped to the sound, turning quickly to see Rydberg standing in the doorway, a light static issuing from his loudspeaker.

“I didn’t invite you in here!” she said in anger and frustration. “Get out! Now!”

The robot turned without a word and moved from the door, Katherine following him out into a small hallway.

“What do you want?” she asked. “Has there been any… news about Derec?”

Rydberg turned back to her. “I did not mean to intrude upon your privacy,” he said. “Please accept my apologies. I’ve brought you food.”

“I’m not hungry.”

Rydberg just stared at her.

“Has there been any word about Derec?” she asked again, softly this time.

“Yes,” the robot replied. “He was seen not three decads ago, but ran away when another of our supervisors called to him.”

She clapped her hands together loudly. “So, he’s alive!”

“Apparently so. Why would he run away? Is this a sign of guilt?”

“It’s a sign that he wants to check out this crazy place without a gaggle of robots hanging all over him.” She moved past him toward the living room. “Now, where’s that food? I’m so hungry I could eat a… ” She stopped herself, then looked at the robot. “I’m hungry.”

“But you just said… ”

“Forget what I just said. Correction!” She caught herself before the robot could explain its memory. “I mean never mind. Where’s the food?”

He led her back down the hall to the living room, where the food sat at the same table she had eaten at the night before. Strangely enough, the room was different, squatter, wider than it had been the previous night, the table closer to the wall.

She moved quickly to the table. There was a variety of what appeared to be fruits and cooked vegetables there. She sat down and tentatively ate a small piece of greenish fruit. It was delicious. Rydberg stood nearby as she greedily sampled everything on the table, all of it good. She didn’t invite the robot to sit with her as Derec had done. The machines were servants and needed to be treated as such. She’d never understand his insistence on treating them as anything other than the machines they were.

“When do we get to make outside radio contact?” she asked once the initial hunger pangs had died down.

“We will all meet later and discuss those questions.”

“Are you going to put us on trial,” she asked, “for the murder of this other human? We are entitled to a trial, you know.”

“Derec has told us that he will try to solve this mystery,” Rydberg said.

Katherine stopped eating and stared at him. “And what if he doesn’t? What if we don’t ever discover what really happened? You have no right to hold us here as it is. We can’t go on indefinitely like this.”

“If he cannot find out the truth of the matter,” Rydberg said, “then we will assume our original supposition to be correct.”

“I don’t believe you,” she said. “You have no right to determine my guilt or innocence without proper evidence. I’m not Derec, and I hold no romantic visions of a robot-controlled world. You cannot be allowed to have any power over the way I live my life. If you want to hold me for murder, you must put me on trial and prove it. If you put me on trial, I must be allowed to defend myself. I therefore demand immediate access to a radio so that I may provide myself with proper defense representation. I want a certified legal rep, and I want one now!”

“We will discuss the situation later today,” the robot said, “after Friend Derec has been returned to us. Meanwhile, your food is getting cold and will lose its appeal.”

“It already has,” Katherine returned, pushing the plate away from herself. She didn’t like the way this was turning. The radio seemed to get more and more distant to her, and with it, any hopes of ever leaving this place. Her arguments to Rydberg were based solely on laws and customs common to Auroran society. But all law, all freedom, was merely a rationalization away where a robot civilization was concerned.

The final result to her was quite simple: the machines were in charge and they could do anything they wanted.

Derec knew nothing with which to compare the size of Robot City, but as he drove its breadth, he couldn’t help but feel its vastness.

As the parts truck moved quickly through the city streets, the round drone bounced from one machine to another, squeaking loudly, its silver body lighting up in dozens of places, then winking out again as it performed automatic (but definitely sub-robotic) pre-troubleshooting functions on the broken machinery. Finally, it came to rest on Derec’s lap, all of its lights blinking madly, its squeaks turning into a high-pitched whine.

“So, where are we going?” he asked the troubleshooter while idly stroking its dome.

The machine whirred and bounced, but never answered. All at once, its whine turned to a loud, siren-like wail.

“Stop it!” Derec ordered, turning to the front of the truck to make sure he wasn’t attracting attention. He bent double over the thing, trying to muffle its sound without success.”

You’re going to have to stop,” he told the thing. “I can’t just… ”

It sent a jolt of electricity through its body, shocking Derec, moving him off.

“All right,” he said, pointing a shaking finger at the silver ball. “I don’t have to take that from you.”

The thing started bouncing up and down, higher and higher. Derec looked both ways over the truck back, then calmly brought up a foot and shoved the thing right off the truck, where it hit the street angrily, its wail louder as it bounced around like a rubber ball.

Within a few blocks, the vehicle slowed its pace, then got in line behind several other trucks, all filled with equipment. Derec got on his knees and looked over the piles of computers.

The trucks were pulled up to a gate, where a whole line of robots were moving up to the truck back, each taking a single piece of equipment and returning with it to a blockhouse that wasn’t much larger than a single doorway. Beside the blockhouse was the most amazing thing Derec had ever seen in his short memory.

A huge, gray machine rumbled softly, yet with undeniable strength and power. From it issued what could only be described as a ribbon of city. In five-meter-square slabs, the city appeared to be simply extruding from underground through the medium of the gray machine.

It pushed itself along, the slabs gradually forming and reforming as they moved, following some incredible preprogramming that actually let them build themselves. And as the slabs formed walls and floors and corners and stories and windows, they spun off in every direction in a slow, graceful dance that pushed against the already existing buildings, the mechanism that triggered the entire magnificent clockwork of Robot City.

It was as if the entire city were one mammoth, living organism always growing outward, always changing and replicating like the cells in a body, moving in imprinted patterns toward a complete, fully formed being.

It was a plan of monumental scale, an atmosphere of total, logical control for a given end. As he watched a skyscraper literally build itself from the ground up, each story pushing up the story above it and self-welding according to some unseen plan, he experienced the grandeur of an idea so vast that his limited knowledge was humbled by its power. This civilization was the product of a mind that refused to believe in limited options, a mind that accepted that what the imagination could conceive, the hands could make.

To such a mind, anything was possible. Even, perhaps, Perihelion.

The truck lurched, nearly knocking him from his knees. It had pulled up to the gate. The line of robots was now reaching into his bed for their equipment.

If all the action was happening below ground, that’s where Derec wanted to be. Hurrying out of the truck, he grabbed a small terminal that looked as if it had been shorted out by water, and took his place behind a robot heading toward that doorway into the ground.

He reached the doorway, cradling the computer like a baby. Warm air greeted him as he stepped through into barely lit darkness. He was confronted by a short flight of stairs leading down, and followed the robot that walked down before him.

The stairs terminated in a large holding area, brightly lit, frenetic with activity. Automated carts carried robots and mining equipment at breakneck pace. The cars zipped around one another in seemingly rehearsed fashion, their movements perfected over time, since it seemed impossible to Derec that they could move so quickly without hitting one another.

On the far wall sat a bank of elevators, perhaps twenty in all, some of them remarkably large. The robots that moved down the stairs headed toward these elevators, apparently going from here to a lower level where repair or scrap work was being done.

Having no idea of where to go, Derec chose an elevator at random and moved toward it with his burden. A large elevator nearby slid open, and a group of minerbots, covered with mud and soot, moved out bearing the non-operating carcass of one of their own above their shoulders.

Derec reached the elevator. It had no formal controls, but opened for him as soon as he stepped near.

A voice boomed behind him. “Nothing awaits you below, but death!”

He turned to see a huge supervisor robot, twice the size of a man, glaring down at him with red photocells. The robot’s body was burnished a bright, shimmering black.

“I’ve come to inspect your operation,” Derec said, feigning authority. He turned back to the elevator and began to step in.

The robot’s arm flashed out, his mammoth pincers clanging loudly around Derec’s forearm, squeezing tightly but not painfully.

“You are caught,” the machine said, and Derec’s computer crashed loudly at his feet.
