From his vantage in the tiny balcony apartment overlooking Streeling University, R. Daneel Olivaw could not feel human grief, lacking the human mental structures necessary for that bitter reassessment and reshaping of neuronal pathways; but, like Lodovik, he could feel a sharp and persistent unease, somewhere between guilt at failure and the warning signals of impending loss of function. The news that one of his most valued cohorts was missing distressed him at the very least in that way. He had lost so many to the tiktoks, guided by the alien meme-entities, it seemed so recently-decades, however, and his discomfort (and loneliness!) still burned.

He had seen the newsfilm in a store window the day before, of the loss of the Spear of Glory and the probable end to any hope of rescue for the citizens of several worlds.

In his present guise, he looked very much as he had twenty millennia before, in the time of his first and perhaps most influential relationship with a human, Elijah Bailey. Of medium height, slender, with brown hair, he appeared about thirty-five human years of age. He had made some small accessions to the changes in human physiology in that time; the fingernails on his pinkie fingers were now gone, and he was some six centimeters taller. Still, Bailey might have recognized him.

It was doubtful that Daneel would have recognized his ancient human friend, however; all but the most general of those memories had long since been stored in separate caches, and were not immediately accessible to the robot.

Daneel had undergone many transformations since that time, the most famous of them being Demerzel, First Minister to the Emperor Cleon I; Hari Seldon himself had succeeded him in that post. Now the time was approaching when Daneel would have to intensify his direct participation in Trantor’s politics, a prospect he found distasteful. The loss of Lodovik would make his work all the more difficult.

He had never enjoyed public displays. He was far more content to operate in the background and let his thousands of cohorts act out public roles. He preferred, in any case, that his robots assert themselves in small ways here and there over time, at key locations, to effect changes that would in turn effect other changes, producing a cascade with (he hoped) the desired results.

In the centuries of his work he had seen a few failures and many successes, but with Lodovik he had hoped to insure his most important goal, the perfection of the Plan, Hari Seldon’s Psychohistory Project, and the settlement of a First Foundation world.

Seldon’s psychohistory had already given Daneel the tools necessary to see the Empire’s future in bleak detail. Collapse, disintegration, wholesale destruction: chaos. There was nothing he could do to prevent that collapse. Perhaps had he acted ten thousand years ago, with then-impossible foresight, using the crude and piecemeal psychohistory then at his disposal, he might have put off this catastrophe. But Daneel could not allow the Empire’s decline and fall to proceed without intervention, for too many humans would suffer and die-over thirty-eight billion on Trantor alone-and the First Law dictated that no human should be harmed or allowed to come to harm.

His duty for all of those twenty thousands of years had been to mitigate human failures and redirect human energies for the greater human good.

To do that, he had mired himself in history, and some of the changes he had effected had resulted in pain, harm, even death. It was the Zeroth Law, first formulated by the remarkable robot Giskard Reventlov, that allowed him to continue functioning under these circumstances.

The Zeroth Law was not a simple concept, though it could be stated simply enough: some humans could be harmed, if by so doing one could prevent harm for the greater number.

The ends justify the means.

This dreadful implication had powered so much agony in human history, but it was no time to engage in that ancient internal debate.

What could he learn from the loss of Lodovik Trema? Nothing, it seemed; the universe sometimes decided things beyond the control of rational action. There was nothing so frustrating and difficult to encompass, for a robot, as a universe indifferent to humans.

Daneel could move anonymously from Sector to Sector, along with the migrating unemployed now pandemic on Trantor. He could maintain contact with his cohorts through a personal communicator or his portable informer, as well as through illegal hookups to the planet’s many networks. Sometimes he dressed as a pitiful street beggar; he spent much of his time in a cramped, dirty apartment in the Trans-Imperial Sector, barely seventy kilometers from the Palace. Nobody wished to look at a figure so old, bent, filthy, and pitiful; in a way, Daneel had become a symbol of the misery he hoped to overcome.

No humans remembered a fictional character who had so enjoyed going out in disguise among the common people, the lower classes, a man of pure and impossibly discerning intellect, a detective much like Daneel’s old friend Elijah Bailey. With Daneel’s frequent memory dumps and adjustments, all that he remembered was a single name and an overall impression: Sherlock.

Daneel was one of the many robots who had become disguised Sherlocks among the masses; tens of thousands throughout the Galaxy, trying not just to solve a mystery, but to prevent further and greater crimes.

The leader of these dedicated servants, the first Eternal, brushed as much of the street’s filth from his rags as he could manage, and left the cramped and empty General Habitation Project hovel in search of finer clothes.

“They’ve searched the entire apartment,” Sonden Asgar moaned, rubbing his elbows and looking smaller and more frail than she had ever seen him before. Klia’s respect for her father had not been high in the last few years, but she still felt a pang for his misery-and an abiding sense of guilt that strengthened a sense of responsibility. “They went through our records-imagine that! Private records! Some Imperial authority…”

“Why your records, Father?” Klia asked. The apartment was a shambles. She could imagine the investigators pulling up cabinets and throwing out the boxes and few dishes within, tugging up the worn carpets…She was glad she hadn’t been here, and for more than one reason.

“Not my records!” Sonden shouted. “They were looking for you. School papers, bookfilms, and they took our family album. With all your mother’s pictures. Why? What have you done now?”

Klia shook her head and upturned a stool to sit. “If they’re looking for me, I can’t stay,” she said.

“Why, daughter? What could-”

“If I’ve done anything illegal, Father, it’s not worth the attention of Imperial Specials. It must be something else…” She thought of the conversation with the man in dusty green, and frowned.

Sonden Asgar stood in the middle of the main room, three meters square, hardly a room at all-more of a closet-and shivered like a frightened animal. “They were not kind,” he said. “They grabbed me and shook me hard…They acted like thugs. I might as well have gotten mugged in Billibotton!”

“What did they say?” Klia asked softly.

“They asked where you were, how you had done in school, how you made your living. They asked whether you knew a Kindril Nashak. Who is that?”

“A man,” she said, hiding her surprise. Kindril Nashak! He had been the kingpin in her greatest success so far, a deal that had put four hundred New Credits in her accounts with the Banker in Billibotton. But even that had been trivial-surely nothing worth their attention. Imperial Special police were supposed to seek out the Lords of the Underground, not clever girls with purely personal ambitions.
