Hummin hurried off, his hand gripping Seldon's upper arm. Seldon found the grip impossible to shake and, feeling like a child in the hands of an impetuous nurse, followed.

  They plunged into an arcade and, before Seldon's eyes grew accustomed to the dimmer light, they heard the burring sound of a ground-car's brakes.

  "There they are," muttered Hummin. "Faster, Seldon." They hopped onto a moving corridor and lost themselves in the crowd.

  7.

  Seldon had tried to persuade Hummin to take him to his hotel room, but Hummin would have none of that.

  "Are you mad?" he half-whispered. "They'll be waiting for you there."

  "But all my belongings are waiting for me there too."

  "They'll just have to wait."

  And now they were in a small room in a pleasant apartment structure that might be anywhere for all that Seldon could tell. He looked about the one-room unit. Most of it was taken up by a desk and chair, a bed, and a computer outlet. There were no dining facilities or washstand of any kind, though Hummin had directed him to a communal washroom down the hall. Someone had entered before Seldon was quite through. He had cast one brief and curious look at Seldon's clothes, rather than at Seldon himself, and had then looked away.

  Seldon mentioned this to Hummin, who shook his head and said, "We'll have to get rid of your clothes. Too bad Helicon is so far out of fashion-"

  Seldon said impatiently, "How much of this might just be your imagination, Hummin? You've got me half-convinced and yet it may be merely a kind of . . . of-"

  "Are you groping for the word 'paranoia'?"

  "All right, I am. This may be some strange paranoid notion of yours."

  Hummin said, "Think about it, will you? I can't argue it out mathematically, but you've seen the Emperor. Don't deny it. He wanted something from you and you didn't give it to him. Don't deny that either. I suspect that details of the future are what he wants and you refused. Perhaps Demerzel thinks you're only pretending not to have the detailsthat you're holding out for a higher price or that someone else is bidding for it too. Who knows? I told you that if Demerzel wants you, he'll get you wherever you are. I told you that before those two splitheads ever appeared on the scene. I'm a journalist and a Trantorian. I know how these things go. At one point, Alem said, 'He's the one we want.' Do you remember that?"

  "As it happens," said Seldon. "I do."

  "To him I was only the 'other motherlackey' to be kept off, while he went about the real job of assaulting you."

  Hummin sat down in the chair and pointed to the bed. "Stretch out, Seldon. Make yourself comfortable. Whoever sent those twoit must have been Demerzel, in my opinion-can send others, so we'll have to get rid of those clothes of yours. I think any other Heliconian in this sector caught in his own world's garb is going to have trouble until he can prove he isn't you."

  "Oh come on."

  "I mean it. You'll have to take off the clothes and we'll have to atomize them-if we can get close enough to a disposal unit without being seen. And before we can do that I'll have to get you a Trantorian outfit. You're smaller than I am and I'll take that into account. It won't matter if it doesn't fit exactly-"

  Seldon shook his head. "I don't have the credits to pay for it. Not on me. What credits I have-and they aren't much-am in my hotel safe."

  "We'll worry about that another time. You'll have to stay here for an hour or two while I go out in search of the necessary clothing."

  Seldon spread his hands and sighed resignedly. "All right. If it's that important, I'll stay."

  "You won't try to get back to your hotel? Word of honor?"

  "My word as a mathematician. But I'm really embarrassed by all the trouble you're taking for me. And expense too. After all, despite all this talk about Demerzel, they weren't really out to hurt me or carry me off. All I was threatened with was the removal of my clothes."

  "Not all. They were also going to take you to the spaceport and put you on a hypership to Helicon."

  "That was a silly threat-not to be taken seriously."

  "Why not?"

  "I'm going to Helicon. I told them so. I'm going tomorrow."

  "And you still plan to go tomorrow?" asked Hummin.

  "Certainly. Why not?"

  "There are enormous reasons why not."

  Seldon suddenly felt angry. "Come on, Hummin, I can't play this game any further. I'm finished here and I want to go home. My tickets are in the hotel room. Otherwise I'd try to exchange them for a trip today. I mean it."

  "You can't go back to Helicon."

  Seldon flushed. "Why not? Are they waiting for me there too?"

  Hummin nodded. "Don't fire up, Seldon. They would be waiting for you there too. Listen to me. If you go to Helicon, you are as good as in Demerzel's hands. Helicon is good, safe Imperial territory. Has Helicon ever rebelled, ever fallen into step behind the banner of an antiEmperor?"

  "No, it hasn't---and for good reason. It's surrounded by larger worlds. It depends on the Imperial peace for security."

  "Exactly! Imperial forces on Helicon can therefore count on the full cooperation of the local government. You would be under constant surveillance at all times. Any time Demerzel wants you, he will be able to have you. And, except for the fact that I am now warning you, you would have no knowledge of this and you would be working in the open, filled with a false security."

  "That's ridiculous. If he wanted me in Helicon, why didn't he simply leave me to myself? I was going there tomorrow. Why would he send those two hoodlums simply to hasten the matter by a few hours and risk putting me on my guard?"

  "Why should he think you would be put on your guard? He didn't know I'd be with you, immersing you in what you call my paranoia."

  "Even without the question of warning me, why all the fuss to hurry me by a few hours?"

  "Perhaps because he was afraid you would change your mind."

  "And go where, if not home? If he could pick me up on Helicon, he could pick me up anywhere. He could pick me up on . . . on Anacreon, a good ten thousand parsecs away-if it should fall into my head to go there. What's distance to hyperspatial ships? Even if I find a world that's not quite as subservient to the Imperial forces as Helicon is, what world is in actual rebellion? The Empire is at peace. Even if some worlds are still resentful of injustices in the past, none are going to defy the Imperial armed forces to protect me. Moreover, anywhere but on Helicon I won't be a local citizen and there won't even be that matter of principle to help keep the Empire at bay."

  Hummin listened patiently, nodding slightly, but looking as grave and as imperturbable as ever. He said, "You're right, as far as you go, but there's one world that is not really under the Emperor's control. That, I think, is what must be disturbing Demerzel."

  Seldon thought a while, reviewing recent history and finding himself unable to choose a world on which the Imperial forces might be helpless. He said at last, "What world is that?"

  Hummin said, "You're on it, which is what makes the matter so dangerous in Demerzel's eyes, I imagine. It is not so much that he is anxious to have you go to Helicon, as that he is anxious to have you leave Trantor before it occurs to you, for any reason-even if only tourist's mania-to stay."

  The two men sat in silence until Seldon finally said sardonically, "Trantor! The capital of the Empire, with the home base of the fleet on a space station in orbit about it, with the best units of the army quartered here. If you believe that it is Trantor that is the safe world, you're progressing from paranoia to outright fantasy."

  "No! You're an Outworlder, Seldon. You don't know what Trantor is like. It's forty billion people and there are few other worlds with even a tenth of its population. It is of unimaginable technological and cultural complexity. Where we are now is the Imperial Sector-with the highest standard of living in the Galaxy and populated entirely by Imperial functionaries. Elsewhere on the planet, however, are over eight hundred other sectors, some of them with subcultures totally different from what we h
ave here and most of them untouchable by Imperial forces."

  "Why untouchable?"

  "The Empire cannot seriously exert force against Trantor. To do so would be bound to shake some facet or other of the technology on which the whole planet depends. The technology is so interrelated that to snap one of the interconnections is to cripple the whole. Believe me, Seldon, we on Trantor observe what happens when there is an earthquake that manages to escape being damped out, a volcanic eruption that is not vented in time, a storm that is not defused, or just some human error that escapes notice. The planet totters and every effort must be made to restore the balance at once."

  "I have never heard of such a thing."

  A small smile flickered its way across Hummin's face. "Of course not. Do you want the Empire to advertise the weakness at its core? However, as a journalist, I know what happens even when the Outworlds don't, even when much of Trantor itself doesn't, even when the Imperial pressure is interested in concealing events. Believe me! The Emperor knows-and Eto Demerzel knows-even if you don't, that to disturb Trantor may destroy the Empire."

  "Then are you suggesting I stay on Trantor for that reason?"

  "Yes. I can take you to a place on Tmntor where you will be absolutely safe from Demerzel. You won't have to change your name and you will be able to operate entirely in the open and he won't be able to touch you. That's why he wanted to force you off Trantor at once and if it hadn't been for the quirk of fate that brought us together and for your surprising ability to defend yourself, he would have succeeded in doing so."

  "But how long will I have to remain on Trantor?''

  "For as long as your safety requires it, Seldon. For the rest of your life, perhaps."

  8.

  Hari Seldon looked at the holograph of himself cast by Hummin's projector. It was more dramatic and useful than a mirror would have been. In fact, it seemed as though there were two of him in the room.

  Seldon studied the sleeve of his new tunic. His Heliconian attitudes made him wish the colors were less vibrant, but he was thankful that, as it was, Hummin had chosen softer colors than were customary here on this world. (Seldon thought of the clothing worn by their two assailants and shuddered inwardly.)

  He said, "And I suppose I must wear this hat."

  "In the Imperial Sector, yes. To go bareheaded here is a sign of low breeding. Elsewhere, the rules are different."

  Seldon sighed. The round hat was made of soft material and molded itself to his head when he put it on. The brim was evenly wide all around, but it was narrower than on the hats his attackers had worn. Seldon consoled himself by noticing that when he wore the hat the brim curved rather gracefully.

  "It doesn't have a strap under the chin."

  "Of course not. That's advanced fashion for young lanks."

  "For young what?"

  "A lank is someone who wears things for their shock value. I'm sure you have such people on Helicon."

  Seldon snorted. "There are those who wear their hair shoulder-length on one side and shave the other." He laughed at the memory.

  Hummin's mouth twisted slightly. "I imagine it looks uncommonly ugly."

  "Worse. There are lefties and righties, apparently, and each finds the other version highly offensive. The two groups often engage in street brawls."

  "Then I think you can stand the hat, especially without the strap."

  Seldon said, "I'll get used to it."

  "It will attract some attention. It's subdued for one thing and makes you look as if you're in mourning. And it doesn't quite fit. Then, too, you wear it with obvious discomfort. However, we won't be in the Imperial Sector long. --Seen enough?" And the holograph flickered out.

  Seldon said, "How much did this cost you?"

  "What's the difference?"

  "It bothers me to be in your debt."

  "Don't worry about it. This is my choice. But we've been here long enough. I will have been described, I'm quite certain. They'll track me down and they'll come here."

  "In that case," said Seldon, "the credits you're spending are a minor matter. You're putting yourself into personal danger on my account. Personal danger!"

  "I know that. But it's my free choice and I can take care of myself."

  "But why-"

  "We'll discuss the philosophy of it later. -I've atomized your clothes, by the way, and I don't think I was seen. There was an energy surge, of course, and that would be recorded. Someone might guess what happened from that-it's hard to obscure any action when probing eyes and mind are sharp enough. However, let us hope we'll be safely away before they put it all together."

  9.

  They traveled along walkways where the light was soft and yellow. Hummin's eyes moved this way and that, watchful, and he kept their pace at crowd speed, neither passing nor being passed.

  He kept up a mild but steady conversation on indifferent topics.

  Seldon, edgy and unable to do the same, said, "There seems to be a great deal of walking here. There are endless lines in both directions and along the crossovers."

  "Why not?" said Hummin. "Walking is still the best form of shortdistance transportation. It's the most convenient, the cheapest, and the most healthful. Countless years of technological advance have not changed that. -Are you acrophobic, Seldon?''

  Seldon looked over the railing on his right into a deep declivity that separated the two walking lanes-each in an opposite direction between the regularly spaced crossovers. He shuddered slightly. "If you mean fear of heights, not ordinarily. Still, looking down isn't pleasant. How far does it go down?"

  "Forty or fifty levels at this point, I think. This sort of thing is common in the Imperial Sector and a few other highly developed regions. In most places, one walks at what might be considered ground level."

  "I should imagine this would encourage suicide attempts."

  "Not often. There are far easier methods. Besides, suicide is not a matter of social obloquy on Trantor. One can end one's life by various recognized methods in centers that exist for the purpose-if one is willing to go through some psychotherapy at first. There are, occasional accidents, for that matter, but that's not why I was asking about acrophobia. We're heading for a taxi rental where they know me as a journalist. I've done favors for them occasionally and sometimes they do favors for me in return. They'll forget to record me and won't notice that I have a companion. Of course, I'll have to pay a premium and, again of course, if Demerzel's people lean on them hard enough, they'll have to tell the truth and put it down to slovenly accounting, but that may take considerable time."

  "Where does the acrophobia come in?"

  "Well, we can get there a lot faster if we use a gravitic lift. Not many people use it and I must tell you that I'm not overjoyed at the idea myself, but if you think you can handle it, we had better."

  "What's a gravitic lift?"

  "It's experimental. The time may come when it will be widespread over Trantor, provided it becomes psychologically acceptable-or can be made so to enough people. Then, maybe, it will spread to other worlds too. It's an elevator shaft without an elevator cab, so to speak. We just step into empty space and drop slowly-or rise slowly-under the influence of antigravity. It's about the only application of antigravity that's been established so far, largely because it's the simplest possible application."

  "What happens if the power blinks out while we're in transit?"

  "Exactly what you would think. We fall and-unless we're quite near the bottom to begin with-we die. I haven't heard of it happening yet and, believe me, if it had happened I would know. We might not be able to give out the news for security reasons-that's the excuse they always advance for hiding bad news-but I would know. It's just up ahead. If you can't manage it, we won't do it, but the corridors are slow and tedious and many find them nauseating after a while."

  Hummin turned down a crossover and into a large recess where a line of men and women were waiting, one or two with children.

  Seldon said in a
low voice, "I heard nothing of this back home. Of course, our own news media are terribly local, but you'd think there'd be some mention that this sort of thing exists."

  Hummin said. "It's strictly experimental and is confined to the Imperial Sector. It uses more energy than it's worth, so the government is not really anxious to push it right now by giving it publicity. The old Emperor, Stanel VI, the one before Cleon who amazed everyone by dying in his bed, insisted on having it installed in a few places. He wanted his name associated with antigravity, they say, because he was concerned with his place in history, as old men of no great attainments frequently are. As I said, the technique may spread, but, on the other hand, it is possible that nothing much more than the gravitic lift will ever come of it."

  "What do they want to come of it?" asked Seldon.

  "Antigrav spaceflight. That, however, will require many breakthroughs and most physicists, as far as I know, are firmly convinced it is out of the question. -But, then, most thought that even gravitic lifts were out of the question."

  The line ahead was rapidly growing shorter and Seldon found himself standing with Hummin at the edge of the floor with an open gap before him. The air ahead faintly glittered. Automatically, he reached out his hand and felt a light shock. It didn't hurt, but he snatched his hand back quickly.

  Hummin grunted. "An elementary precaution to prevent anyone walking over the edge before activating the controls." He punched some numbers on the control board and the glitter vanished.

  Seldon peered over the edge, down the deep shaft.

  "You might find it better-or easier," said Hummin, "if we link arms and if you close your eyes. It won't take more than a few seconds."

  He gave Seldon no choice, actually. He took his arm and once again there was no hanging back in that firm grip. Hummin stepped into nothingness and Seldon (who heard himself, to his own embarrassment, emit a small squeak) shuffled off with a lurch.

  He closed his eyes tightly and experienced no sense of falling, no feeling of air movement. A few seconds passed and he was pulled forward. He tripped slightly, caught his balance, and found himself on solid ground.
