"Yes," said Baley. "I have to think and, after last night, a calm day like this - sunny, cloudless, mild scarcely seems dangerous. I'll go indoors if I get agoraphobic. I promise. So will you join me?"
"Yes, sir."
"Good." Baley led the way. They reached the tree and Baley touched the trunk gingerly and then stared at his finger, which remained perfectly clean. Reassured that, leaning against the trunk would not dirty him, he inspected the ground and then sat down carefully and rested his back against the tree.
It was not nearly as comfortable as the back of a chair would have been, but there was a feeling of peace (oddly, enough) that perhaps he would not have had inside a room.
Giskard remained standing and Baley said, "Won't you sit down - too?"
"I am as comfortable standing, sir."
"I know that, Giskard, but I will think better if I don't have to look up at you."
"I could not guard you against possible harm as efficiently if I were seated, sir."
"I know that, too, Giskard, but there is no reasonable danger at the moment. My mission is over, the case is solved, Dr. Fastolfe's position is secure. You can risk being seated and I order you to sit down."
Giskard at once sat down, facing Baley, but his eyes continued to wander in, this direction and that and were ever alert.
Baley looked at the sky, through the leaves of the tree green against blue, listened to the susurration of insects and to the sudden call of a bird, noted a disturbance of grass nearby that might have meant a small animal passing by, and again thought - how oddly peaceful it how different this peacefulness was from the clamor of the City. This was a quiet unhurried peace.
For the first time, Baley caught a faint suggestion of how it might be to prefer Outside to the City. He caught himself being thankful to his experiences on Aurora, to the storm most of all - for he knew now that he would be able to leave Earth and face the conditions, of whatever new world he might settle on, he and Ben - and perhaps Jessie.
He said, "Last night, in the darkness of the storm, I wondered if I might have seen Aurora's satellite were it not for the clouds. It has a satellite, if I recall my reading correctly."
"Two, actually, sir. The larger is Tithonus, but it is still so small that it appears only as a moderately bright star. The smaller is not visible at all to the unaided eye and is simply called Tithonus, when it is referred to at all."
"Thank you. - And thank you, Giskard, for rescuing me last night." He looked at the robot. "I don't know the proper way of thanking you."
"It is not necessary to thank me at all. I was merely following the dictates of the First Law. I had no choice in the matter."
"Nevertheless, I may even owe you my life and it is important that you know I understand this. - And now, Giskard, what ought I to do."
"Concerning what matter, sir?"
"My mission is over. Dr. Fastolfe's views are secure. Earth's future may be assured. It would seem I have nothing more to do and yet there is the matter of Jander."
"I do not understand, sir."
"Well, it seems settled that he died by a chance shift of positronic potential in his brain, but Fastolfe admits the chance of that is infinitesimally small. Even with Amadiro's activities, the chance, though possibly greater, would remain infinitesimally small. At least, so Fastolfe thinks. It continues to seem to me, then, that Jander's death was one of deliberate roboticide. Yet I don't dare raise this point now. I don't want to unsettle matters that have been brought to such a satisfactory conclusion. I don't want to put Fastolfe in jeopardy again. I don't want to make Gladia unhappy. I don't know what to do. I can't talk to a human being about this, so I'm talking to you, Giskard."
"Yes, sir."
"I can always order you to erase whatever I have said and to remember it no more."
"Yes, sir."
"In your opinion, what ought I to do?"
Giskard said, "If there is a roboticide, sir, there must be someone, capable of committing the act. Only Dr. Fastolfe is capable, of committing it and he says he did not do it."
"Yes we started with that situation. I believe Dr. Fastolfe and am quite certain he did not do it."
"Then how could there have been a roboticide, sir?"
"Suppose that someone else knew as much about robots as Dr. Fastolfe does, Giskard."
Baley drew up his knees and clasped his hands around them. He did not look at Giskard and seemed lost in thought.
"Who might that be, sir?" asked Giskard.
And finally, Baley reached the crucial point.
He said, "You, Giskard."

If Giskard had been human, he might have simply stared, silent and stunned; or he might have raged angrily; or shrunk back in terror; or had any of a dozen responses. Because he was a robot, he showed no sign of any emotion whatever and simply said, "Why do you say so, sir?"
Baley said, "I am quite certain, Giskard, that you know exactly how I have come to this conclusion, but you will do me a favor if you allow me, in this quiet place and in this bit of time before I must leave, to explain the matter for my own benefit. I would like to hear myself talk about it. And I would like you to correct me where I am wrong."
"By all means, sir."
"I suppose my initial mistake was to suppose that you are a less complicated and more primitive robot than Daneel is, simply because you look less human. A human being will always suppose that, the more human a robot is, the more advanced, complicated, and intelligent he will be. To be sure, a robot like you is easily designed and one like Daneel is a great problem for men like Amadiro and can be handled only by a robotics genius such as Fastolfe. However, the difficulty in designing Daneel lies, I suspect, in reproducing all the human aspects such as facial expression, intonation of voice, gestures and movements that are extraordinarily intricate but have nothing really to do with complexity of mind. Am I right?"
