“Yes, Madam Gladia.”

“And all sorts of other things about them?”

“Yes, Madam Gladia. Dr. Fastolfe once asked me to gather astronomical data so that he could have them at his fingertips without having to consult his computer. He used to say it was friendlier to have me tell him than to have his computer do so.” Then, as though, to anticipate the next question, “He did not explain why that should be so.”

Gladia raised her left arm and made the appropriate gesture. Her house was at once illuminated. In the soft light that now reached her, she was subliminally aware of the shadowy figures of several robots, but she paid no attention to that. In any well-ordered establishment, there were always robots within reach of human beings, both for security and for service.

Gladia took a last fugitive glimpse at the sky, where the stars had now dimmed in the scattered light. She shrugged lightly. It had been quixotic. What good would it have done even if she had been able to see the sun of that now-lost world, one faint dot among many? She might as well choose a dot at random, tell herself it was Solaria’s sun, and stare at it.

Her attention turned to R. Daneel. He waited for her patiently, the planes of his face largely in shadow.

She found herself thinking again how little he had changed since she had seen him on arriving at Dr. Fastolfe’s establishment so long ago. He had undergone repairs, of course. She knew that, but it was a vague knowledge that one pushed away and kept at a distance.

It was part of the general queasiness that held good for human beings, too. Spacers might boast of their iron health and of their life-spans of thirty to forty decades, but they, were not entirely immune to the ravages of age. One of Gladia’s femurs fit into a titanium-silicone hip socket. Her left thumb was totally artificial, though no one could tell that without careful ultrasonograms. Even some of her nerves had been rewired. Such things would be true of any Spacer of similar age from any of the fifty Spacer worlds (no, forty-nine, for now Solaria could no longer be counted).
