the frame around until Kaelor was suspended in an upright position, eyes straight ahead, feet dangling a half meter off the floor. He stared straight ahead, his body motionless, his eyes sightless. The test meter cable still hung from his neck, and the meter’s display showed a series of diagnostic numbers, one after the other, in blinking red.
Seeing Kaelor strapped in that way, Fredda was irresistibly reminded of an ancient drawing she had seen somewhere, of a torture victim strapped down on a frame or rack not unlike the one that held Kaelor now. That’s the way it works, she thought. Strap them down, mistreat them, try and force the information out of them before they die. It was a succinct description of the torturer’s trade. She had never thought before that it might apply to a roboticist as well. “I bet you don’t like this any better than I do,” she said, staring at the robot. She was not sure if she was talking to Kaelor or Davlo.
Now Davlo looked on Kaelor, and could not take his eyes off him. “Yesterday, he grabbed me and stuffed me under a bench and used his body to shield mine. He risked his life for mine. He’d remind me himself that the Three Laws compelled him to do it, but that doesn’t matter. He risked his life for mine. And now we’re simply going to risk his life.” He paused a moment, and then said it in plainer words. “We’re probably about to kill him,” he said in a flat, angry voice. “Kill him because he wants to protect us—all of us—from me.”
Fredda glanced at Davlo, and then looked back at Kaelor. “I think you’d better let me do the talking,” she said.
For a moment she thought he was about to protest, insist that a man ought to be willing to do this sort of job for himself. But instead his shrugged, and let out a small sigh. “You’re the roboticist,” he said, still staring straight at Kaelor’s dead eyes. “You know robopsychology.”
And there are times I wished I knew more human psychology, Fredda thought, giving Davlo Lentrall a sidelong glance. “Before we begin,” she said, “there’s something you need to understand. I know that you ordered Kaelor built to your own specifications. You wanted a Constricted First Law robot, right?”
“Right,” said Lentrall, clearly not paying a great deal of attention.
“Well, you didn’t get one,” Fredda said. “At least not in the sense you might think. And that’s what set up the trap you’re in now. Kaelor was designed to be able to distinguish hypothetical danger or theoretical danger from the real thing. Though most high-function robots built on Inferno are capable of distinguishing between real and hypothetical danger to humans, they in effect choose not to do so. In a sense, they let their imaginations run away with them, worry that the hypothetical might become real, and fret over what would happen in such a case, and treat it as if were real, just to be on the safe side of the First Law. Kaelor was, in effect, built without much imagination—or what passes for imagination in a robot. He is not capable of making that leap, of asking, ‘What if the hypothetical became real?’ ”
“I understand all that,” Davlo said irritably.
“But I don’t think you understand the next part,” Fredda said with more coolness than she felt. “With a robot like Kaelor, when the hypothetical, the imaginary, suddenly does become real, when it dawns on such a robot that it has been working on a project that is real, that poses real risks to real people—well, the impact is enormous. I would compare it to the feeling you might have if you suddenly discovered, long after the fact, that, unbeknownst to yourself, some minor, even trifling thing you had done turned out to cause the death of a close relative. Imagine how hard that would hit you, and you’ll have some understanding of how things felt to Kaelor.”
Davlo frowned and nodded. “I see your point,” he said. “And I suppose that would induce a heightened First Law imperative?”
“Exactly,” Fredda said. “My guess is that, by the time you switched him off, Kaelor’s mental state was approaching a state of First Law hypersensitivity, rendering him excessively alert to any possible danger to humans. Suddenly realizing that he had unwittingly violated First Law already would only make it worse. Once we switch Kaelor back on, he’s going to revert to that state instantly.”
“You’re saying he’s going to be paranoid,” Davlo said.
“It won’t be that extreme,” said Fredda. “He’ll be very careful. And so should we be. Just because his body is immobilized, it doesn’t mean that he won’t be capable of committing—of doing something rash.”
Davlo nodded grimly. “I figured that much,” he said.
“Are you ready, then?”
He did not answer at first. He managed to tear his eyes away from Kaelor. He paced back and forth a time or two, rubbed the back of his neck in an agitated manner, and then stopped, quite abruptly. “Yes,” he said at last, his eyes locked on the most distant corner of the room.
“Very well,” she said. Fredda pulled an audio recorder out of her tool pouch, switched it on, and set on the floor in front of Kaelor. If they got what they needed, she wanted to be sure they had a record of it.
She stepped around to the rear of the maintenance frame, opened the access panel, and switched Kaelor back on. She moved back around to the front of the maintenance frame, and positioned herself about a meter and a half in front of it.
Kaelor’s eyes glowed dimly for a moment before they flared to full life. His head swiveled back and forth, as he looked around himself. He looked down at his arms and legs, as if confirming what he no doubt knew already— that his body had been immobilized. Then he looked around the room, and spotted Lentrall. “It would appear that you figured it out,” Kaelor said. “I was hoping for all our sakes that you would not.”
“I’m sorry, Kaelor, but I—”
“Dr. Lentrall, please. Let me handle this,” said Fredda, deliberately speaking in a cold, sharp-edged, professional tone. This had to be impersonal, detached, dispassionate if it was going to work. She turned to Kaelor, up there on the frame. No, call the thing by its proper name, even if she had just now realized what that name was. The rack. The torturer’s rack. He hung there, paralyzed, strapped down, pinned down, an insect in a collector’s sample box, his voice and his expressionless face seeming solemn, even a little sad. There was no sign of fear. It would seem Kaelor had either too little imagination, or too much courage, for that.
Suddenly she felt a little sick, but she forced herself to keep all hint of that out of her voice and expression. She told herself she was imposing human attributes on Kaelor, investing him with characteristics and emotions he simply did not have. There was no practical difference between having him up on that rack and having a malfunctioning aircar up on a hydraulic lift in a repair shop. She told herself all of that, and more, but she did not believe a word of it. She forced herself to look steadily, coolly, at Kaelor, and she addressed him. “Kaelor, do you know who I am?”
“Yes, of course. You are Dr. Fredda Leving, the roboticist.”
“Quite right. Now then, I am going to give you an order. You are to answer all my questions, and answer them as briefly as possible. Do not provide any information I do not ask for, or volunteer any information. Regard each question by itself. The questions will not be related to each other. Do you understand?” she asked.
“Certainly,” said Kaelor.
“Good.” Fredda was hoping, without much confidence, that she would be able to ask her questions in small enough pieces that no one question would present a First Law violation. And of course the questions would be related—that part was a baldfaced lie. But it might be a convincing enough lie to help Kaelor live through this. She knew for certain that asking, straight-out, the one big question to which they needed an answer would be absolutely catastrophic. She dared not ask for the big picture. She could only hope Kaelor would be willing and able to provide enough tiny pieces of the puzzle.
The trouble was, Kaelor had to know what she was doing as well as she did. How far would he be able to go before First Law imperative overrode the Second Law compulsion to obey orders?
There was one last thing she could do to help Kaelor. Fredda did not have any realistic hope that the Third Law’s requirement for self-preservation would help sustain Kaelor, but she could do her best to reinforce it all the same. “It is also vital for you to remember that you are important as well. Dr. Lentrall needs you, and he very much wants you to continue in his employ. Isn’t that so, Doctor?”
Lentrall looked up from the hole he was staring at in the floor, and glanced at Fredda before settling his gaze on Kaelor. “Absolutely,” he said. “I need you very much, Kaelor.”
“Thank you for saying so,” Kaelor said. He turned his gaze back on Fredda. “I am ready for your questions,” he said.
“Good,” said Fredda. It might well help Kaelor if she kept the questions as disordered as possible, and tossed in a few unrelated ones now and then. “You work for Dr. Lentrall, don’t you?” she asked.
“Yes,” said Kaelor.
“How long have you been in his employ?”
