Asimov's Future History Volume 4 (5 page)

“Jehoshaphat,” said Baley between his teeth. “I’m going. I’m going.” He got up from his desk, headed for the office, and R. Sammy was silent.

Baley said as he entered, “Damn it, Commissioner,
don’t
send that thing after me, will you?”

But the Commissioner only said, “Sit down, Lije. Sit down.”

Baley sat down and stared. Perhaps he had done old Julius an injustice. Perhaps the man hadn’t slept after all. He looked fairly beat.

The Commissioner was tapping the paper before him. “There’s a record of a call you made to a Dr. Gerrigel at Washington by insulated beam.”

“That’s right, Commissioner.”

“There’s no record of the conversation, naturally, since it was insulated. ‘What’s it all about?”

“I’m after background information.”

“He’s a roboticist, isn’t he?”

“That’s right.”

The Commissioner put out a lower lip and suddenly looked like a child about to pout. “But what’s the point? What kind of information are you after?”

“I’m not sure, Commissioner. I just have a feeling that in a case like this, information on robots might help.” Baley clamped his mouth shut after that. He wasn’t going to be specific, and that was that.

“I wouldn’t, Lije. I wouldn’t. I don’t think it’s wise.”

“What’s your objection, Commissioner?”

“The fewer the people who know about all this, the better.”

“I’ll tell him as little as I can. Naturally.”

“I still don’t think it’s wise.”

Baley was feeling just sufficiently wretched to lose patience.

He said, “Are you ordering me not to see him?”

“No. No. You do as you see fit. You’re heading this investigation. Only..

“Only what?”

The Commissioner shook his head. “Nothing.–Where is
he?
You know who I mean.”

Baley did. He said, “Daneel’s still at the files.”

The Commissioner paused a long moment, then said, “We’re not making much progress, you know.”

“We’re not making any so far. Still, things may change.”

“All right, then,” said the Commissioner, but he didn’t look as though he really thought it were all right.

R. Daneel was at Baley’s desk, when the latter returned.

“Well, and what have
you
got?” Baley asked gruffly.

“I have completed my first, rather hasty, search through the files, partner Elijah, and I have located two of the people who tried to track us last night and who, moreover, were at the shoe store during the former incident.”

“Let’s see.”

R. Daneel placed the small, stamp-size cards before Baley. They were mottled with the small dots that served as code. The robot also produced a portable decoder and placed one of the cards into an appropriate slot. The dots possessed electrical conduction properties different from that of the card as a whole. The electric field passing through the card was therefore distorted in a highly specific manner and in response to that specification the three-by-six screen above the decoder was filled with words. Words which, uncoded, would have filled several sheets of standard size report paper. Words, moreover, which could not possibly be interpreted by anyone not in possession of an official police decoder.

Baley read through the material stolidly. The first person was Francis Clousarr, age thirty-three at time of arrest two years before; cause of arrest, inciting to riot; employee at New York Yeast; home address, so-and-so; parentage, so-and-so; hair, eyes, distinguishing marks, educational history, employment history, psychoanalytic profile, physical profile, data here, data there, and finally reference to the photo in the rogues’ gallery.

“You checked the photograph?” asked Baley.

“Yes, Elijah.”

The second person was Gerhard Paul. Baley glanced at the material on that card and said, “This is all no good.”

R. Daneel said, “I am sure that cannot be so. If there is an organization of Earthmen who are capable of the crime we are investigating, these are members. Is that not an obvious likelihood? Should they then not be questioned?”

“We’d get nothing out of them.”

“They were there, both at the shoe store and in the kitchen. They cannot deny it.”

“Just being there’s no crime. Besides which, they can deny it. They
can
just say they weren’t there. It’s as simple as that. How can we prove they’re lying?”

“I saw them.”

“That’s no proof,” said Baley, savagely. “No court, if it ever came to that, would believe that you could remember two faces in a blur of a million.”

“It is obvious that I can.”

“Sure. Tell them what you are. As soon as you do that, you’re no witness. Your kind have no status in any court of law on Earth.”

R. Daneel said, “I take it, then, that you have changed your mind.”

“What do you mean?”

“Yesterday, in the kitchen, you said there was no need to arrest them. You said that as long as I remembered their faces, we could arrest them at any time.”

“Well, I didn’t think it through,” said Baley. “I was crazy. It can’t be done.”

“Not even for psychological reasons? They would not know we had no legal proof of their complicity in conspiracy.”

Baley said, tensely, “Look, I am expecting Dr. Gerrigel of Washington in half an hour. Do you mind waiting till he’s been here and gone? Do you mind?”

“I will wait,” said R. Daneel.

Anthony Gerrigel was a precise and very polite man of middle height, who looked far from being one of the most erudite roboticists on Earth. He was nearly twenty minutes late, it turned out, and quite apologetic about it. Baley, white with an anger born of apprehension, shrugged off the apologies gracelessly. He checked his reservation on Conference Room D, repeated his instructions that they were not to be disturbed on any account for an hour, and led Dr. Gerrigel and R. Daneel down the corridor, up a ramp, and through a door that led to one of the spy-beam-insulated chambers.

Baley checked the walls carefully before sitting down, listening to the soft burr of the pulsometer in his hand, waiting for any fading of the steady sound which would indicate a break, even a small one, in the insulation. He turned it on the ceiling, floor, and, with particular care, on the door. There was no break.

Dr. Gerrigel smiled a little. He looked like a man who never smiled more than a little. He was dressed with a neatness that could only be described as fussy. His iron-gray hair was smoothed carefully back and his face looked pink and freshly washed. He sat with a posture of prim stiffness as though repeated maternal advice in his younger years concerning the desirability of good posture had rigidified his spine forever.

He said to Baley, “You make this all seem very formidable.”

“It’s quite important, Doctor. I need information about robots that only you can give me, perhaps. Anything we say here, of course, is top secret and the City will expect you to forget it all when you leave.” Baley looked at his watch.

The little smile on the roboticist’s face winked away. He said, “Let me explain why I am late.” The matter obviously weighed upon him. “I decided not to go by air. I get airsick.”

“That’s too bad,” said Baley. He put away the pulsometer, after checking its standard settings to make last-minute certain that there was nothing wrong with
it
, and sat down.

“Or at least not exactly airsick, but nervous. A mild agoraphobia. It’s nothing particularly abnormal, but there it is. So I took the expressways.”

Baley felt a sudden sharp interest. “Agoraphobia?”

“I make it sound worse than it is,” the roboticist said at once. “It’s just the feeling you get in a plane. Have you ever been in one, Mr. Baley?”

“Several times.”

“Then you must know what I mean. It’s that feeling of being surrounded by nothing; of being separated from–from empty air by a mere inch of metal. It’s very uncomfortable.”

“So you took the expressway?”

“Yes.”

“All the way from Washington to New York?”

“Oh, I’ve done it before. Since they built the Baltimore-Philadelphia tunnel, it’s quite simple.”

So it was. Baley had never made the trip himself, but he was perfectly aware that it was possible. ‘Washington, Baltimore, Philadelphia, and New York had grown, in the last two centuries, to the point where all nearly touched. The Four-City Area was almost the official name for the entire stretch of coast, and there were a considerable number of people who favored administrational consolidation and the formation of a single super-City. Baley disagreed with that, himself. New York City by itself was almost too large to be handled by a centralized government. A larger City, with over fifty million population, would break down under its own weight.

“The trouble was,” Dr. Gerrigel was saying, “that I missed a connection in Chester Sector, Philadelphia, and lost time. That, and a little difficulty in getting a transient room assignment, ended by making me late.”

“Don’t worry about that, Doctor. What you say, though, is interesting. In view of your dislike for planes, what would you say to going outside City limits on foot, Dr. Gerrigel?”

“For what reason?” He looked startled and more than a little apprehensive.

“It’s just a rhetorical question. I’m not suggesting that you really should. I want to know how the notion strikes you, that’s all.”

“It strikes me very unpleasantly.”

“Suppose you had to leave the City at night and walk cross country for half a mile or more.”

“I–I don’t think I could be persuaded to.”

“No matter how important the necessity?”

“If it were to save my life or the lives of my family, I might try....” He looked embarrassed. “May I ask the point of these questions, Mr. Baley?”

“I’ll tell you. A serious crime has been committed, a particularly disturbing murder. I’m not at liberty to give you the details. There is a theory, however, that the murderer, in order to commit the crime, did just what we were discussing; he crossed open country at night and alone. I was just wondering what kind of man could do that.”

Dr. Gerrigel shuddered. “No one I know. Certainly not I. Of course, among millions I suppose you could find a few hardy individuals.”

“But you wouldn’t say it was a very likely thing for a human being to do?”

“No. Certainly not likely.”

“In fact, if there’s any other explanation for the crime, any other
conceivable
explanation, it should be considered.”

Dr. Gerrigel looked more uncomfortable than ever as he sat bolt upright with his well-kept hands precisely folded in his lap. “Do you have an alternate explanation in mind?”

“Yes. It occurs to me that a robot, for instance, would have no difficulty at all in crossing open country.”

Dr. Gerrigel stood up. “Oh, my dear sir!”

“What’s wrong?”

“You mean a robot may have committed the crime?”

“Why not?”

“Murder? Of a human being?”

“Yes. Please sit down, Doctor.”

The roboticist did as he was told. He said, “Mr. Baley, there are two acts involved: walking cross country, and murder. A human being could commit the hatter easily, but would find difficulty in doing the former. A robot could do the former easily, but the latter act would be completely impossible. If you’re going to replace an unlikely theory by an impossible one–”

“Impossible is a hell of a strong word, Doctor.”

“You’ve heard of the First Law of Robotics, Mr. Baley?”

“Sure. I can even quote it: A robot may not injure a human being, or, through inaction, allow a human being to come to harm.” Baley suddenly pointed a finger at the roboticist and went on, “Why can’t a robot be built without the First Law? What’s so sacred about it?”

Dr. Gerrigel looked startled, then tittered, “Oh, Mr. Baley.”

“Well, what’s the answer?”

“Surely, Mr. Baley, if you even know a little about robotics, you must know the gigantic task involved, both mathematically and electronically, in building a positronic brain.”

“I have an idea,” said Baley. He remembered well his visit to a robot factory once in the way of business. He had seen their library of bookfilms, long ones, each of which contained the mathematical analysis of a single type of positronic brain. It took more than an hour for the

average such film to be viewed at standard scanning speed, condensed though its symbolisms were. And no two brains were alike, even when prepared according to the most rigid specifications. That, Baley understood, was a consequence of Heisenberg’s Uncertainty Principle. This meant that each film had to be supplemented by appendices involving possible variations.

Oh, it was a job, all right. Baley wouldn’t deny that.

Dr. Gerrigel said, “Well, then, you must understand that a design for a new type of positronic brain, even one where only minor innovations are involved, is not the matter of a night’s work. It usually involves the entire research staff of a moderately sized factory and takes anywhere up to a year of time. Even this large expenditure of work would not be nearly enough if it were not that the basic theory of such circuits has already been standardized and may be used as a foundation for further elaboration. The standard basic theory involves the Three Laws of Robotics: the First Law, which you’ve quoted; the Second Law, which states, ‘A robot must obey the orders given it by human beings except where such orders would conflict with the First Law,’ and the Third Law, which states, ‘A robot must protect its own existence as long as such protection does not conflict with the First or Second Law.’ Do you understand?”

R. Daneel, who, to all appearances, had been following the conversation with close attention, broke in. “If you will excuse me, Elijah, I would like to see if I follow Dr. Gerrigel. What you imply, sir, is that any attempt to build a robot, the working of whose positronic brain is not oriented about the Three Laws, would require first the setting up of a new basic theory and that this, in turn, would take many years.”

The roboticist looked very gratified. “That is exactly what I mean, Mr...”

Baley waited a moment, then carefully introduced R. Daneel: “This is Daneel Olivaw, Dr. Gerrigel.”
