Gladia’s brows drew together in a puzzled frown. “But—” she began and then subsided.
Giskard went on, “It strikes me that it might be well for you to inform the crew of this. It might well ease their distrust of Lady Gladia if you stress what her initiative and courage have meant to every man in the crew, since it has kept them alive. It might also give them an excellent opinion of your own foresight in insisting on having her on board on this occasion, perhaps even against the advice of your own officers.”
D.G. let loose a great shout of laughter. “Lady Gladia, I see now why you will not be separated from these robots. They are not only as intelligent as human beings, they are every bit as devious. I congratulate you on your having them. And now, if you don’t mind, I must hurry the crew. I don’t want to stay on Solaria for one moment more than necessary. And I promise you that you won’t be disturbed for hours. I know you can use freshening and rest as much as I can.”
After he was gone, Gladia remained for a while in deep thought, then turned to Giskard and said in Auroran Common, a patter version of Galactic Standard that was widespread on Aurora and difficult for any non-Auroran to understand, “Giskard, what is all this nonsense about the burning out of circuits?”
“My lady,” said Giskard, “I advanced it only as a possibility and nothing more. I thought it well to emphasize your role in putting an end to the overseer.”
“But how could you think he would believe that a robot could bum out that easily?”
“He knows very little about robots, madam. He may traffic in them, but he is from a world that doesn’t make use of them.”
“Yet I know a great deal about them and so do you. The overseer showed no signs whatever of balancing circuits; no stuttering, no trembling, no behavior difficulty of any kind. It just—stopped.”
Giskard said, “Madam, since we do not know the precise specifications to which the overseer was designed, we may have to be content with ignorance as to the rationale behind the freeze.”
Gladia shook her head. “Just the same, it’s puzzling.”

D.G.’s ship was in space again, surrounded by the everlasting changelessness of the endless vacuum.
It had not come too soon for Gladia, who had but imperfectly suppressed the tension that arose from the possibility that a second overseer—with a second intensifier—might arrive without warning. The fact that it would be a quick death if it happened, an unexperienced death, was not quite satisfying. The tension had spoiled what would have otherwise been a luxuriant shower, along with various other forms of renewal of comfort.
It was not till after actual takeoff, after the coming of the soft, distant buzz of the protonic jets, that she could compose herself to sleep. Odd, she thought as consciousness began to slip away, that space should feel safer than the world of her youth, that she should leave Solaria with even greater relief the second time than she had the first.
But Solaria was no longer the world of her youth. It was a world without humanity, guarded over by distorted parodies of humanity; humanoid robots that made a mockery of the gentle Daneel and the thought-filled Giskard.
She slept at last—and while she slept, Daneel and Giskard, standing guard, could once more speak to each other.
Daneel said, “Friend Giskard, I am quite certain that it was you who destroyed the overseer.”
“Mere was clearly no choice, friend Daneel. It was purely an accident that I arrived in time, for my senses were entirely occupied with searching out human beings and I found none. Nor would I have grasped the significance of events if it were not for Lady Gladia’s rage and despair. It was that which I sensed at a distance and which caused me to race to the scene—barely in time. In that respect, Lady Gladia did save the situation, at least as far as the captain’s existence and yours were concerned. I would still have saved the ship, I believe, even if I had arrived too late to save you.” He paused a moment and added, “I would have found it most unsatisfactory, friend Daneel, to arrive too late to save you.”
Daneel said, with a grave and formal tone of voice, “I thank you, friend Giskard. I am pleased that you were not inhibited by the human appearance of the overseer. That had slowed my reactions, as my appearance had slowed hers.”
“Friend Daneel, her physical appearance meant nothing to me because I was aware of the pattern of her thoughts. That pattern was so limited and so entirely different from the full range of human patterns that there was no need for me to make any effort to identify her in a positive manner. The negative identification as nonhuman was so clear I acted at once. I was not aware of my action, in fact, until after it had taken place.”
“I had thought this, friend Giskard, but I wished confirmation lest I misunderstand. May I assume, then, that you feel no discomfort over having killed what was, in appearance, a human being?”
“None, since it was a robot.”
“It seems to me that, had I succeeded in destroying her, I would have suffered some obstruction to the free positronic flow, no matter how thoroughly I understood her to be a robot.”
“The humanoid appearance, friend Daneel, cannot be fought off when that is all one can directly judge by. Seeing is so much more immediate than deducing. It was only because I could observe her mental structure and concentrate on that, that I could ignore her physical structure.”
“How do you suppose the overseer would have felt if she had destroyed us, judging from her mental structure?”
“She was given exceedingly firm instructions and there was no doubt in her circuits that you, and the captain were nonhuman by her definition.”
“But she might have destroyed Madam Gladia as well.”
“Of that we cannot be certain, friend Daneel.”
“Had she done so, friend Giskard, would she have survived? Have you any way of telling?”
Giskard was silent for a considerable period. “I had insufficient time to study the mental pattern. I cannot say what her reaction might have been had she killed Madam Gladia.”
“If I imagine myself in, the place of the overseer”—Daneel’s voice trembled and grew slightly lower in pitch, “it seems to me that I might kill a human being in order to save the life of another human being, whom, there might be some reason to think, it was more necessary to save. The action would, however, be difficult and damaging. To kill a human being merely in order to destroy something I considered nonhuman would be inconceivable.”
“She merely threatened. She did not carry through the threat.”
“Might she have, friend Giskard?”
“How can we say, since we don’t know the nature of her instructions?”
“Could the instructions have so completely negated the First Law?”
Giskard said, “Your whole purpose in this discussion, I see, has been to raise this question. I advise you to go no further.”
Daneel said stubbornly, “I will put it in the conditional, friend Giskard. Surely what may not be expressed as fact can be advanced as fantasy. If instructions could be hedged about with definitions and conditions, if the instructions could be made sufficiently detailed in a sufficiently forceful manner, might it be possible to kill a human being for a purpose less overwhelming than the saving of the life of another human being?”
