ENCOUNTER WITH KIN
THE WOLF-CREATURES DID not attack again that day, though Derec and Mandelbrot heard them often or glimpsed them shadowing their progress through the trees. Derec watched them, his weapon at ready but not certain that he could fire it again, not with the knowledge that they were intelligent. Once or twice, he called out to the wolves or gestured to one of them slipping past, but they never responded.
By noon, the calls had faded behind them, and they were left alone in the forest.
“I think we must have passed only through a far comer of their territory,” Mandelbrot said. “The attack was simply to ensure that we came no closer to their den or whatever, and they stayed with us to be certain that we left. It is a lucky accident that our path did not lead us in the wrong direction.”
“It would have been luckier if it hadn’t led us to them at all,” Derec answered morosely.
“We must be very careful,” Mandelbrot said. “There are likely to be more tribes in the area. Master Derec, do you think that perhaps these wolf-creatures would be able to help us? Perhaps we do not have to find the Robot City.”
“No,” Derec replied, but the question made him glance over to Mandelbrot. “We need Robot City. Stone Age technology won’t do either of us any good. Are you going to repair your knee with a flint joint? Are you going to find servos and high-grade lubricants and a new optical circuit?”
Mandelbrot was silent after that, but Derec knew that the robot was experiencing a mental quandary after their encounter with the wolf-creatures. Mandelbrot was obviously troubled by their sentience. It showed in the questions he asked, in the way that he looked at Derec’s weapon, in the attention the robot paid to the movement of the wolf-creatures watching them.
Knowing the robot as he did and having seen the reactions of the original Robot City robots to Wolruf, Derec knew where the problem lay. He could almost hear balances shifting within the robot’s mind.
“Mandelbrot,” he said as they walked, “how do you regard the wolf-creatures? How do the Laws apply to them?”
“Are you asking if I consider them ‘human,’ Master Derec?”
“Yes. I suppose that’s the basic question. Are they human? I know you came to class Wolruf as human.”
“Positronic minds are as variable as those of humans, Master Derec. What is human? There are many ways to answer the question, all of them valid and all of them with shortcomings. Certainly it is more than simply the way a being looks; even among the humans I have seen there is a great variance.”
Derec was shaking his head. “But every one of them you’ve encountered has been Homo sapiens, a bipedal, upright-walking mammal descended from apes and able to trace their ancestry back to Earth. These wolf-things, whatever they are, aren’t bipedal, aren’t apes, and aren’t descended from anything on Earth.”
“That description fits Wolruf as well.”
“Point taken. But you haven’t answered my question yet. Let me give you a hypothetical situation: If I told old Balzac back on Aurora that Wolruf was a great danger to me and the only way to remove the danger was to kill her, would Balzac do it?”
“The danger would have to be demonstrated, Master Derec. Your word would not be enough.”
“All right, assume it was. Assume I can convince Balzac of the imminent risk. I know I couldn’t order Balzac to kill a human, but what about Wolruf? Balzac’s seen her walk and talk and use the computer and pilot a ship. Would he still be able to protect me?”
Mandelbrot’s eyes gleamed. His bad leg dragged through underbrush, and the robot came to a halt alongside Derec. “You are asking this because you are concerned that I will not be able to protect you should these wolf-creatures attack again.”
Derec shrugged. He patted his broken arm, then waggled the gun in his hand. “We’re not in the greatest of shapes, Mandelbrot. Neither one of us. First, I don’t want to have to use this thing, not after what we know now, but if I have to in order to stay alive, I probably will. What about you, Mandelbrot?”
The robot seemed to consider that for a long moment, and for a moment Derec wa
s afraid that he might have inadvertently driven the robot into positronic lockup. Then servo motors whirred as it began walking again. “I have searched my data banks and checked the functions of my logic system, Master Derec, and the readouts are very erratic. My priority circuits are almost in balance. Had I never met Wolruf, had I never seen sentient alien lifeforms, and did I not have memories of Robot City in my mind, I am sure it would be different.”
“What are you saying, Mandelbrot?”
“That I do not know what I would do, Master Derec. I do not know.”
He could have insisted. He could have made it a direct question and stressed the importance of an answer — the Second Law would have forced Mandelbrot to answer. “Mandelbrot, do you consider these wolf-creatures to be as human as me?”
But somehow it didn’t seem right to ask.
After all, Derec wasn’t sure of the answer himself.
All of the sudden, it was too late to ask.
They had continued to walk even after the sun had set. The moons were up and bright, and Derec wanted to cover as much ground as they could before settling for the night.
Mandelbrot’s comlink overheard the short-range call. “Derec,” it said. “There are robots in the near vicinity.” Mandelbrot’s flat, emotionless voice sounded strangely dispassionate. “They seem to be searching for Hunter-Seekers that are also supposed to be in this vicinity.”
Derec couldn’t help the grin that split his face. “That’s wonderful, Mandelbrot. Now we can finally get out of here.” He focused his thoughts inward, trying to contact the robots via the chemfets in his body, but the link was still not there. “Can you contact them, Mandelbrot? Tell them there’s a human in need of aid —”
Derec got no farther.
A fury in gray fur hit him from behind. Claws raked his shoulder as he was sent sprawling to the ground. His broken arm hit a root protruding from the earth. Derec screamed involuntarily as the world went dim. His attacker, a wolf-creature, had turned to attack again, snarling. Derec tried to raise himself up with his good hand and could not. The wolf-creature gathered itself to pounce.
Derec knew he was going to die.
The wolf-creature, sentient or not, was going to rip his throat out.
Derec struggled to crawl, to move. He saw a blur of metal and heard the whine of overtaxed gears. Mandelbrot had moved to intercept the wolf-creature. But the gear-whine became a wail and the robot’s leg seized up entirely. Mandelbrot started to fall, internal gyros protesting, as the wolf-creature leapt.
Mandelbrot’s Avery-type arm snaked out even as he fell, even as the body of the wolf-creature bounded over the robot’s prone body. Mandelbrot grabbed, held, and threw. It was all he could do. The wolf yelped in surprise and pain, then the body thudded against the tree next to Derec and slumped to the ground.
The stars in Derec’s head went away slowly. His vision cleared to see Mandelbrot lying next to him and staring. “Master Derec?” the robot asked. “I think I may have killed it.” His voice seemed to grind from his metallic larynx, halting. Derec understood immediately that the robot was very near lockup. His one good eye was dim, and his hand was fisted tightly.
“Mandelbrot,” he said desperately. “You had to do it. I would have died otherwise. I’m... I’m okay, I think. You saved my life, Mandelbrot. You had no choice. No choice at all. If you lockup now, you’re committing a First Law offense. I need you.”
Derec tried to rise and fell back again with a groan. He’d intended it as an act — it wasn’t. The pain was all too real.
His discomfort stirred Mandelbrot. The eye came back to full brilliance, the hand unclenched, and the robot stood up, his left leg sticking out stiffly in front of him. Gently, he helped Derec to his feet. “Thank you, Mandelbrot,” Derec said and went to the wolf-creature. It was not breathing. Up close, it was magnificent: muscular, the thick fur rich with glossy highlights in the moonlight, the face expressive even in death. Derec’s gaze was caught by the forepaws. They were true hands, despite the deadly curved claws, the long fingers delicate and jointed, the thumb opposed and ideal for grasping. The creature must walk on its knuckles, he realized, for the tops of those joints were wide, flat, and bony. Except for that difference, the hands might have been those of a human.
Derec sighed. Mandelbrot was right to be bothered by the death.
The massive head lolled, the neck broken. Derec stroked the fine, gray-tipped black fur of the creature with his good hand. “You couldn’t help it, Mandelbrot,” he said again, knowing the robot was watching him. “You have to know that.”
He stopped. His fingers had found something in the fur of the creature’s neck. Derec pulled it loose. It was a necklace of colored wire. Soldered to the end of one of the strands was a small circuit board. Derec’s breath hissed in with surprise. “Mandelbrot, look at this! Mandelbrot?”
Mandelbrot was no longer listening. The robot had suddenly straightened in an attitude of listening. “Master Derec! The robots I heard a few minutes ago — they are being attacked!”
From somewhere very close by, they could hear the sudden, savage howling of wolves.
Chapter 19
ESCAPE FROM THE CITY
SILVERSIDE’S REACTION TO being seen by the Hunters was swift and powered by the Three Laws. The Third Law forced her to try to save herself. Second Law demanded that she follow the orders of humans, and though she was their leader, KeenEye’s commands to save the kin still carried weight; the First Law compelled her to do whatever she could to keep her people alive.
Which meant the prime consideration was that Central be destroyed.
SilverSide changed her shape as the Hunters turned to look up at her. She drew back the parafoil and thickened the body. Even as the Hunters raised their hands to fire their lasers, she became a streamlined, compact mass instead of a glider, and she dropped the last thirty feet like a massive stone, crashing heavily into the central column of Central. Laser beams crisscrossed the air where she had been; delicate circuitry smashed under her fall. SilverSide changed back to wolf form even as she rose from the wreckage of the core unit. She went to the wide panels surrounding the core and pushed with all the strength of her durable body. A panel toppled, striking the next in line — the array went down like a row of dominoes, sparking and crashing, the thunder of their destruction ringing in the cavernous room.
SilverSide fled the room, howling the ritual triumph of a victor even as she anticipated the Hunters’ lasers cutting her down. It didn’t matter to her. She’d done what she’d come to do.
But nothing happened; the Hunters had stopped.
Already confusion was spreading through the city — she could hear it, a thousand voices crying out in the VoidTongue that the OldMother had given her. WalkingStones were asking Central for instructions, but Central was not replying, would never reply. The alarm was spreading out through the various levels of this krajal-like society.
EMERGENCY! Central core memory damaged and off-line Command program inactive: secondary routines down.
Activate supervisory backups.
Behind her, SilverSide heard the Hunters stir. She raced into the corridor beyond Central’s room. There were no WalkingStones in sight there. She quickly altered herself once more to appear as one of the Hill of Stars’ Hunters, depending on the disguise to give her cover as she headed for the exit from the place. She listened to the continuing dialogue in her head.
City command given to Supervisor units Alpha, Beta, Gamma. The general announcement went out first over all frequencies, then three new voices boomed in her head. The direction finder in her skull indicated that all three were in widely scattered sections of the city.
ALPHA: Normal city subroutines accessed. City functions on-line and programming reinstated.
BETA: Alert situation! Central computer destroyed. Attacking unit in shape of local wolf-creatures is rogue robot. Repeat, attacking unit is robot not under control of City Supervisors.
