For the first time since being freed from the sealed room, her fears began to overcome her anger at the situation as she turned her body to edge herself off the dizzying height to begin her climb downward. The wind pulled viciously at her like cold, prying hands; her ears and nose went numb, and her fingers tingled with the cold.
Though the pyramid was made from the same material as the rest of the city, it wasn’t the same in any other respect. It was rigid and unbending, its face set with patterns of holes that she and Derec had used as hand and footholds previously, and in which they had hidden the Key on their first descent.
Her mind whirled as she climbed, slowly, so slowly. How far down had it been? She had been moving fast, and Derec, carrying the Key, had been unable to keep up. They had stopped for a conference and decided to hide the Key and continue without it. How far down? A fourth of the climb, barely a fourth, in the leftmost hole of the pattern that ran down the center of the structure.
She continued downward, her fingers hurting now, her eyes looking upward, trying to gauge her distance just right. She began testing the holes in the repeated pattern, to no avail. She still hadn’t reached the place. Something wet and cold hit her hard on the back. Her hands almost pulled out of their holds reflexively. It was a raindrop, and it wet the entire back of her one-piece.
She was running out of time.
The pattern of holes repeated again as she inched downward, and when she looked up, squinting against the frigid wind, she knew she had reached the place.
Hugging the pyramid face with the last of her strength, she slowly reached out, sticking her hand into the leftmost hole of the pattern.
The Key was gone.
“No!” she screamed loudly into the teeth of the monster, and, as if in response, the rain tore from the heavens in blinding, bludgeoning sheets to silence her protests.
Derec stood at the exit door to the Extruder Station and listened to the rain pounding against the door, and watched the small puddle that had somehow made its way under the sealed entry. Katherine was out there somewhere, and Wohler. Nothing had been heard from either of them since before the start of the rain. Avernus had made contact with the Compass Tower, and though both had been seen there, neither was there now.
With the rain controlling the day, everything had come to a standstill, making searching impossible, making contact with the central core impossible, making everything except the almighty building project slow to nothing. It was maddening.
He pounded the door, his fist sinking in, cushioning. He wanted to open those doors and run into the city and find her for himself-but he knew what that meant. Most likely, nothing would be known until the rain abated the next morning.
He turned from the door and walked down the stairs to the holding area and the six robot supervisors who awaited him there. His mind was awash in anxiety.
“Supervisor Rydberg has proposed a plan, Friend Derec,” Euler said. “Perhaps you will comment on it.”
Derec looked at Rydberg, trying to bring his mind back to the present. Why did the woman affect him this way? “Let’s hear your plan,” he said.
“We can go ahead and devise our evacuation schedule for the robots working underground,” Rydberg said. “It seems that when morning comes, you will be able to contact the core and halt the replication. It will be too late to dig through to the cavern in time, but at least we will have the opportunity to spare our mine workers before the floods.”
“Why do you have to give up like this?” Derec said, exasperated. “You’ve heard the reasons for the defenses. Can’t you just stop them now and use the digging equipment to begin excavating the cavern?”
Waldeyer, the squat, wheeled supervisor, said, “The central core is our master program. We cannot abandon it. Only the central core can judge the veracity of your statements and make the final decision.”
“I’m going to reprogram the central core,” Derec answered, too loudly. “I’m going to change its definition of ‘veracity.’ And besides, the Laws of Robotics are your master program, and the Second Law states that you will obey a human command unless it violates the First Law. I’m commanding you to halt the mining processes and begin digging through to the drainage cavern.”
“The defensive procedures were designed by the central core to protect the city, which is designed to protect human life,” Waldeyer replied. “The central core must be the determining factor in any decision to abandon the defenses. Though your arguments sound humane, they may, ultimately, be in violation of the First Law; for if the central core determines that your conclusions are erroneous, then shutting down the defenses could be the most dangerous of all possible decisions.”
Derec felt as if he were on a treadmill. All argument ultimately led back to the central core. And though he was sure that the central core would back off once he programmed the information about human blood into it, he had no way to prove that to the robots who, in turn, refused to do anything to halt the city’s replication until they’d received that confirmation from central.
Then an idea struck him, an idea that was so revisionist in its approach that he was frightened at first even to think out its effects on the robots. What he had in mind would either liberate their thinking or send them into a contradictory mental freeze-up that could destroy them.
“What do you think of Rydberg’s plan?” Avernus asked him. “It will save a great many robots.”
Avernus-that was it-Avernus the humanitarian. Derec knew that his idea would destroy the other robots, but Avernus, he was different. Avernus leaned toward the humane, a leaning that could just possibly save himself and the rest of Robot City.
“I will comment on the evacuation plan later,” Derec said. “First, I’d like to speak with Avernus alone.”
“We make decisions together,” Euler said.
“Why?” Derec asked.
“We’ve always done it that way,” Rydberg said.
“Not any more,” Derec said, his voice hard. “Unless you can give me a sound, First Law reason why I shouldn’t speak with Avernus alone, I will then assume you are violating the Laws yourselves.”
Euler walked to the center of the room, then turned slowly to look at Avernus. “We’ve always done it this way,” he said.
Avernus, the giant, moved stoically toward Euler, putting a larger pincer on the robot’s shoulder. “It won’t hurt anything, this once, if we go against our own traditions.”
“But traditions are the hallmark of civilization,” Euler said.
“Survival is also one of the hallmarks,” Derec replied, looking up at Avernus. “Are you willing?”
“Yes,” Avernus answered without hesitation. “We will speak alone.”
Derec led Avernus to the elevators, then had a thought and returned to Euler. He unwrapped the fabric bandage from his cut arm and handed it to the supervisor. “Have the blood analyzed, the data broken down on disc so I can feed it to the core.”
“Yes, Derec,” Euler said, and it was the first time the supervisor had addressed him without the formal declaration, Friend. Maybe they were all growing up a little bit.
Derec then joined Avernus in the elevator, pushing the down arrow as the doors slid closed. They only traveled down for a moment before Derec pushed the emergency stop button; the machine jerked to a halt.
“What is this about?” Avernus asked.
“I want to make a deal with you,” Derec said.
“What sort of deal?”
“The lives of your robots for one of your digging machines.”
Avernus just stared at him. “I do not understand.”
“Let’s talk about the Third Law of Robotics,” Derec said. “You are obligated by the Third Law to protect your own existence as long as it doesn’t interfere with the First or Second Laws. In your case, with your special programming, I can easily extend the Third Law to include the robots under your control.”
“Go on.”
“My deal is a simple one. Rydberg has suggested an eva
cuation plan that could save the robots in the mines from the flooding that is sure to occur if the cavern is not excavated. The evacuation plan depends completely on my reprogramming the central core to halt the replication. For if I don’t, the city will have to keep replicating, even to its own destruction… that destruction to include the robots who are working underground.”
“I understand that,” Avernus said.
“All right.” Derec took a deep breath. What he was getting ready to propose would undoubtedly freeze out the positronics of any of the other robots; the contradictions were too great, the choices too impossible to make. But with Avernus… maybe, just maybe. “Unless you give me one of the digging machines so I can begin the excavation myself, I will refuse to reprogram the central core, thereby condemning all your robots to stay underground during the flooding.”
Avernus red eyes flared brightly. “You would… kill so many?”
“I would save your city and your robots!” Derec yelled. “It’s all or nothing. Give me the machine or suffer the consequences.”
“You ask me to deny the central core program that protects the First Law.”
“Yes,” Derec said simply, his voice quieting. “You have got to make the creative leap to save your robots. Somewhere in that brain of yours, you’ve got to make a value judgment that goes beyond your programming.”
Avernus just stood there, quaking slightly, and Derec felt tears welling up in his eyes, knowing the torture he was putting the supervisor through. If this failed, if he, in effect, killing Avernus by killing his mind, he’d never be able to forgive himself.
The big robot’s eyes flashed on and off several times, and suddenly his body shuddered violently, then stopped. Derec heard a sob escape his own lips. Avernus bent to him.
“You will have your digging machine,” the robot told him, “and me to help you use it.”
Chapter 13. The Central Core
Even as Katherine clung doggedly to the face of the pyramid, she knew that her ability to hold on could be measured in no more than minutes, as the rain lashed savagely at her and the winds worked to rip her off the patterned facade.
The ground lay several hundred meters below, calling to her. As her body went totally numb in the freezing downpour, her strong survival instinct was the only thing keeping her hanging on.
Her brain whirled, rejecting its own death while trying desperately to prepare for it, and through it all, she could hear the wind calling her name, over and over.
“Katherine!”
Closer now, the sound grew more pronounced. It seemed to come from below.
“Katherine!”
For the first time since she’d begun her climb, she risked a look downward, in the direction of the sound. She blinked through the icy water that streamed down her face only to see an apparition, a gray mass moving quickly up the face below her, proof that her mind was already gone.
“Katherine, hang on! I’m coming!”
In disbelief, she watched the apparition coming closer. And as her arms ached, trying to talk her into letting go and experiencing peace, she saw a golden hand reach from under the gray lump and grasp a handhold in one of the cutouts.
Wohler!
“Please hold on!”
“I can’t!” she called back, surprised to hear the hysteria in her own voice. And as if to reinforce the idea, her left hand lost its grip, her arm falling away from the building, the added pressure sending cramping pain through her right arm still lodged in the hole.
The robot below hurried his pace. The wind, getting beneath the tarp he wore to protect himself from the rain, pulled it away from his body to float like a huge, prehistoric bird.
“P-please… ” she called weakly, her right arm ready to give out.
“Hold on! Please hold on!”
The urgency in his voice astounded her, giving her an extra ounce of courage, a few more seconds when seconds were everything. And as she felt her hand slip away for good and all, his large body had wedged in behind her, holding her up against the facade.
Wohler clamped solidly in hand and footholds just above and below hers and he completely enveloped her, protecting. She let herself relax, all the strength immediately oozing out of her, Wohler supporting her completely.
“Are you unhurt?” the robot asked in her ear.
“I-I think so,” she answered in a small voice. “What happens now?”
“We can only wait,” Wohler said, his voice sounding somehow ragged. “An old Earth proverb says, ‘Patience is a bitter plant but it has sweet fruit.’ Survival w-will be our fruit… Friend Katherine.”
“Friend Wohler,” she responded, tears mixing with the cold rain on her face. “I want to th-thank you for coming up here for me.”
But Wohler didn’t answer.
The supervisors as a group stood behind the gateway excavator that Derec and Avernus operated. Neither helping nor hindering, they simply took it all in, no doubt unable to appreciate the thought processes that had led the big robot to pull the machine away from his mining crews and their replication labors, to put it to work simply clearing a path for something that, at this point, was no more than mere potential.
Derec had seen excavators like these before. On the asteroid where he had first awakened to find he had no identity, the robots had used identical machines to cut out the guts of the asteroid in their search for the Key to Perihelion.
The gateway was a marvel, for it demolished and rebuilt at the same time. Derec sat with Avernus at the two cabin control panels, watching the boom arms cutting into rock face nearly a hundred feet distant. One of the boom arms bore rotary grinders, the other microwave lasers that tore frantically at the core of the planet, chewing it up as it went. There were numerous conveyors and pulleys for the removal and scanning of potential salvage material, but none of these were in use right now. They were simply grinding and compressing the excavated rock and earth, the gateway itself using the materials to build a strong tunnel behind-smooth rock walls, reinforcing synthemesh, even overhead lamps.
They were creeping toward the cavern, every meter a meter closer to possible salvation. They had been working through the night, Derec desperately trying to let the effort keep his mind off Katherine and Wohler. It wasn’t working. There had been no word of them since before the storm had begun nearly ten hours ago. Had they been alive, he would have heard by now.
There was always the chance that Katherine had retrieved the Key and left, perhaps waiting out the rain in the gray void of Perihelion, or perhaps finding her way to another place. But that didn’t explain Wohler’s absence.
During the grueling hours spent working the gateway, Avernus and Derec had conversed very little, both, apparently, lost in their own thoughts. Derec worried for Avernus, who he knew was going through a great many internal recriminations that could only be resolved with a satisfactory outcome and subsequent vindication of his actions.
“Derec!” came Euler’s voice from the newly built tunnel behind; it was the first time the robot had spoken to them since the operation had begun.
Derec looked at his watch. It was nearly five a.m. He shared a glance with Avernus. “Yes!” he called back.
“The rain has abated,” Euler returned. “The missing have been located!”
Derec resisted the urge to jump from the controls and charge out of there. He still had work to do. He looked at Avernus. “What now?”
“Now we will see,” the robot said. “We must locate the core and reprogram.”
“Should I leave you here to continue operations and go with someone else to the core?”
“No,” Avernus said with authority. “I am supervisor of the underground and know my way around it. I also… must know the outcome. Can you understand that?”
Derec reached out and punched off the control board, stopping new digging and bringing all operants to the standby position. “You bet I can understand it. Let’s go!”
They moved out of the gateway, squeezing
past stacked up cylinders to join the other supervisors in the tunnel behind. It was the first time Derec had looked back at their handiwork. The tunnel he and Avernus had made stretched several hundred yards behind them, nearly as far he could see.
“Where are Katherine and Wohler?” he asked. “Are they all right?”
“No one knows,” Rydberg said. “They are clinging to the side of the Compass Tower, nearly a hundred meters above the surface, but they have not responded to voice communication, nor have they attempted to come down.”
Derec’s heart sank. They’d been out all night in the rain.
It looked bad.
“Are rescue operations underway?” he asked.
“Utility robots are now scaling the Tower to determine the extent of the problem for emergency disposition,” Euler said.
“The central core,” Avernus said to Dante. “Tell me where it is right now.”
“Tell me honestly, Euler,” Derec said. “Will my presence at the Tower facilitate the rescue operation?”
“Tower rescue has always been part of our basic program, for reasons no one can fathom,” the robot said. “Standard operating procedure has already been initiated. You could only hinder the operation.”
“Good,” Derec said. Of course Tower rescue was standard. The overseer had worried that, should the trap door to the office below become jammed, he would be caught on the Tower, unable to get down. The almighty overseer didn’t mind letting everyone else twist slowly in the wind, but he wasn’t going to let himself be uncomfortable on the Tower.
Dante spoke up from the terminal in his tram car. “The central core is in Quadrant 2, Tunnel D-24, moving to the north.”
Avernus nodded and looked at Derec. “We must hurry,” he said, “lest all our work be in vain.”
“Work is already in vain,” Waldeyer said to Avernus. “Because of your unauthorized impoundment of the gateway excavator, the on-hand raw iron consignments have dropped dangerously low. Within an hour, replication efforts will begin falling behind schedule.”
The big robot simply hung his head, looking at the floor.
