hey could in fact be controlled precisely. The superficial mechanics of the process were known. Each ship possessed five main-drive verfliers, and five auxiliaries. They located coordinates in space (how?), and, once set, the ship went there. Again, how? It then returned unerringly to its place of origin, or usually did, if it did not run out of fuel or encounter a mischance-a triumph of cybernetics that S. Ya. knew no human agency could reproduce. The difficulty was that until this very second no human being knew quite how to read the controls. But what about the next second, or the one after that? With information pouring in, from the Food Factory and Heechee Heaven; with Dead Men talking; with at least one semicompetent human pilot, the boy, Wan-with all this, and especially with the flood of new knowledge that might be unlocked from the prayer fans... How long before some of the mysteries were solved? Perhaps not very long at all. S. Ya. wished she could be a part of it all, as her classmates had become. As her husband had become. She wished even more that she did not suspect what part he most wanted to play. But the suspicion remained. If Robin could make a Heechee ship fly him to any destination he chose in all the universe, she thought she knew what that destination would be. Semya Yagrodna Lavorovna-Broadhead called to her secretary, "How much time do I have?" The program appeared and said, "It is now five twenty-two. Dr. Liederman is expected at six forty-five. You will then be prepared for the procedure, which will occur at eight o'clock. You have a little more than an hour and a quarter. Perhaps you would like to rest?" S. Ya. chuckled. It always amused her when her own programs offered her advice. She did not, however, feel any need to respond to it. "Have menus been prepared for today and tomorrow?" she asked. "Nyet, gospozha." That was both a relief and a disappointment. At least Robin had not prescribed more fattening foods for today-or perhaps his prescription had been overruled, because of the operation? "Select something," she ordered. The program was quite capable of preparing menus. It was only because of Robin himself that either of them ever gave a thought to such routine chores. But Robin was Robin, and there were times when cooking was a hobby for him, cutting onions paper-thin for a salad and standing to stir a stew for hours. Sometimes what he produced was awful, sometimes not; Essie was not critical, because she was not very interested in what she ate. And also because she was grateful that she felt no need to concern herself with such matters; in this respect, at least, Robin surpassed her father. "No, wait," she added, struck with a thought. "When Robin comes home he will be hungry. Serve him a snack-those crullers, and the New Orleans coffee. As at the Cafe du Monde." "Da, gospozha." How devious you are, thought Essie, smiling to herself. One hour and twelve minutes left. It would do no harm to rest. On the other hand, she was not sleepy. She could, she thought, interrogate her medical program again. But she had no real wish to hear about the procedures she faced an additional time. Such large pieces to take from someone else's body for the sake of her own! The kidney, yes. One might well sell that and still have something left. As a student, Essie had known comrades who had done that, might even have done it herself if she had been just a shade poorer than she actually was. But, although she knew very little more of anatomy than her father had taught her at his knee, she knew enough to be sure that the person, or persons, who had given her all those other tissues would not have enough left to go on living with. It was a queasy feeling. Almost as queasy as that other feeling that came with knowing that, even with Full Medical, from this particular invasion of her person by Wilma Liederman's knives she might not return. Still an hour and eleven minutes. Essie sat up once more. Whether she was to live or not, she was as dutiful a wife as she had been a daughter, and if Robin wished her to concern herself with prayer fans and Heechee she would. She addressed the computer terminal. "I wish the Albert Einstein program." 12 Sixty Billion Gigabits When Essie Broadhead said, "I wish the Albert Einstein program," she set a large number of events in motion. Very few of these events were visible to the unaided senses. They did not take place in the macroscopic physical world, but in a universe composed largely of charges and pathways operating on the scale of the electron. The individual units were tiny. The total was not, being made up of some sixty billion gigabits of information. At Akademogorsk, young S. Ya. 's professors had schooled her in the then current computer logics of ion optics and magnetic bubbles. She had learned to trick her computers into doing many marvelous things. They could find million-digit prime numbers or calculate the tides on a mud-flat for a thousand years. They could take a child's scribble of "House" and "Daddy" and refine it into an engineer's rendering of an architectural plan, and a tailor's dummy of a man. They could rotate the house, add a sunporch, sheath it in stucco or cover it with ivy. They could shave off a beard, add a wig, costume the man for yachting or golfing, for boardroom or bar. These were marvelous programs for nineteen-year-old Semya. She found them thrilling. But she had grown since then. By comparison with the programs she was now writing, for her secretary, for "Albert Einstein" and for her many clients, those early ones were slow and stumbling caricatures. They did not have the advantage of circuits borrowed from Heechee technology, or of a circulating memory store of 6 X b'9 bits. Of course, even Albert did not use all sixty billion gigabits all the time. For one thing, they were not all shared. Even the shared stores were occupied by tens of thousands of programs as subtle and complicated as Albert, and by tens of millions of duller ones. The program called "Albert Einstein" slipped through and among the thousands and the millions without interference. Traffic signals warned him away from occupied circuits. Guideposts led him to subroutines and libraries needed to fulfill his functions. His path was never a straight line. It was a tree of branching decision points, a lightning-stroke of zigzag turns and reverses. It was not truly a "path", either; Albert never moved. He was never in a specific place to move from. It is at least arguable whether Albert "was" anything at all. He had no continuous existence. When Robin Broadhead was through with him and turned him off he ceased to be, and his subroutines picked up other tasks. When he was turned on again he recreated himself from whatever circuits were idle, according to the program S. Ya. had written. He was no more real than an equation, and no less so than God. "I wish..." S. Ya. Lavorovna-Broadhead had said. Before her voice was halfway through the first vowel the sound-activated gate in the monitor's receiver summoned up her secretarial program. The secretary did not appear. She read the first trace of the name that followed... "-the Albert Einstein..." -matched it against her command store, made a probabilistic assessment of the rest and issued an instruction. That was not all the secretary did. Before that she had recognized the voice of S. Ya. and confirmed that it was that of an authorized person-the person who had written her, in fact. She checked her store for undelivered messages, found several, and weighed their urgency. She made a quick sweep of Essie's telemetry readings to estimate her physical condition, retrieved the memory of her proximate surgery, balanced them against the messages and the present instruction, and decided the messages need not be delivered, and in fact could be handled by Essie's surrogate. All that took very little time and involved only a minor fraction of the secretary's full program. She did not need to remember, for instance, what she was supposed to look like or how her voice was supposed to sound. So she did not bother. The secretary's instruction woke "Albert Einstein". He did not at first know that he was Albert Einstein. As he read his program he discovered several things about himself. First, that he was an interactive information-retrieval program, whereupon he searched for and found addresses for the principal categories of information he was supposed to supply. Second, that he was heuristic and normative, which obliged him to look for the rules, in the form of go and no-go gates, that determined his decision-making. Third, that he was the property of Robin a. k. a. Robinette, Rob, Robby, Bob or Bobby-Stetley Broadhead and would be required to interact with him on a basis of "knowing" him. This impelled the Albert program to access the Robin Broadhead files, and rehearse their contents-by far the most time-consuming part of his task so far. When all this was done he discovered his name and the details of his appearance. He made a series of arbitrary choices of costume-pullover sweater, or stained gray sweatshirt; slippers or frayed tennis shoes with a toe poking out; socks or none-and appeared in the tank of the monitor in the guise of the real Albert Einstein, pipe in hand, mild eyes humorously inquiring, before the last echo of the command had died. "...program." He had had plenty of time. It had taken Essie nearly four-tenths of a second to speak his name. As she had spoken in English, he greeted her in the same language. "Good..." quick check of local time, "morning," fast assessment of Essie's mood and condition, "Mrs. Broadhead." If she had been dressed for the office he would have called her "Lavorovna." Essie studied him appraisingly for several seconds, an infinity of time for Albert. He did not waste it. He was a shared-time program, and the parts of his capacity that were not in active use at any particular pico-second busied themselves at other tasks. Whatever task was going. While he waited, parts of him were excused to help other programs make a weather forecast for a sport-fishing vessel leaving Long Island Sound, teach the conjugation of French verbs to a little girl, animate a sexual doll for a wealthy, and quirky, old recluse, and tally gold prices received from the Peking exchange. There were almost always other tasks on line. When there were not, there were the waiting batch-process files of less urgent problems-nuclear particle path analysis, the refinement of asteroid orbits, the balancing of a million checkbooks-that any of the sixty billion gigabits might turn a hand to in an idle moment. Albert was not the same as Robin's other programs-the lawyer, the doctor, the secretary, the psychoanalyst, or any of the surrogates who functioned for Robin Broadhead when Robin was busy or disinclined. Albert shared many memories with them. They freely accessed each other's files. Each had a specific universe of action, tasked for specific needs; but they could not carry out their tasks without awareness of each other. Apart from that, they were each the personal property of Robin Broadhead, slaved to his will. So sophisticated was Albert that he could read contextual clues and deduce imperatives. He was not limited in his responses by what Robin said to him. He was able to read deeper questions from the totality of everything Robin had ever said, to any of his programs. Albert could not betray a confidence of Robin's, or fail to recognize what was confidential. Generally. There were exceptions. The person who had written Albert's program in the first place could easily write an overriding command, and had. "Robin instructed you to prepare summaries for me," Essie told her creation. "Give them to me now." She watched critically and also admiringly as the program she bad written nodded, scratched its ear with its pipestem and began to speak. Albert was quite a good program, she thought with pride. For a collection of electronic impulses living in rag stores-weakly crystalline dichalcogenides with the structure of a wet dishrag-Albert was a rather attractive person. She adjusted her tubes and piping and leaned back against pillows to listen to what Albert had to say. It was all most exceedingly interesting. Even to her, even at this time when in-what was it? in less than one hour ten minutes she would be sponged and stripped and shaved and basted for further invasions of her inner person. As all she demanded of the Albert program at this time was edited memories of conversations that had already occurred, she knew that he had dismissed large parts of himself to other work. But what was left, she observed critically, was quite solid. The transition from the interactive Albert waiting for her question to the remembered Albert talking to her husband was done smoothly and without jumps-if one did not look for such minor imperfections as that the pipe was suddenly alight, and the socks abruptly pulled up over the ankles. Satisfied, Essie paid attention to the content of what was going on. It was not just one conversation, she perceived. There were at least three. Robin must have been spending a lot of time talking to his science program in Brasilia, and while one part of her mind was listening to the exciting news from Heechee Heaven another part was smiling at herself. How amusing that she should be pleased at this evidence that he had not used his hotel suite for other purposes! (Or at least not exclusively, she amended.) He could not have been blamed if he had chosen a living companion instead. Even a female one. Under the circumstances, with a main lover in no condition to be very responsive, she would certainly have felt free to do the same. (Well, not certainly. There was enough early Soviet prudishness left in Essie for at least a doubt.) But she admitted to herself that she was pleased, and then made herself attend to the truly fascinating things that were being said. So much happening! So much to absorb! First, the Heechee. The Heechee in Heechee Heaven were not Heechee! Or at least those Old Ones were not. It was proved by the bio-assay of the DNA, Albert was earnestly assuring her husband, punctuating his arguments with pipe thrusts. The bioassay had produced not an answer but a puzzle, a basic chemistry that was neither human, nor yet inhuman enough to come from creatures evolved around some other star. "Also," said Albert, puffing, "there is the question of the Heechee seat. It does not fit a human being. But neither does it fit the Old Ones. So for whom was it designed? Alas, Robin. We do not know." A quick flicker, the socks now gone, the pipe out and being filled, and Albert was talking about prayer fans. He had not, Albert apologized, unriddled the fans. The literature was vast but he had searched it all. There was no imaginable application of energy and no instrumentation that had not been applied to them. Yet they had stayed mute. "One can speculate," Albert said, striking a match to his pipe, "that all of the fans left for us by the Heechee are garbled, perhaps to tantalize us. I do not believe this. Rafliniert 1st der Herr Hietschie, aber Boshaft 1st er nicht," In spite of everything, Essie laughed out loud. Der Herr Hietschie indeed! Had she written this sense of comedy into her program? She thought of interrupting him to command that he display this section of his instructions, but already that replay had ended and a slightly less rumpled Albert was talking about astrophysics. Here Essie almost closed her ears, for she quickly had enough of curious cosmologies. Was the universe open-ended or closed? She did not strongly care. Was some large quantity of mass "missing", in the sense that not enough could be observed to account for known gravitational effects? Very well, then let it stay missing. Essie felt no need to go looking for it. Someone's fantasy of storms of indetectible pious, and someone else-someone named Kiube's-notion that mass might be created from nothing, interested her very little. But when the conversation switched to black holes, she paid close attention. She was not really concerned with the subject. She was concerned with Robin's concern for it. And that, she told herself justly as Albert rambled on, was petty of her. Robin had kept no mean secrets. He had told her at once of the love of his life, the woman named Gelle-Klara Moynlin whom he had abandoned in a black hole-had told her, actually, far more than she wanted to know. She said, "Stop." Instantly the three-dimensional figure in the tank abandoned the word it had been speaking in midsyllable. It gazed politely at her, awaiting orders. "Albert," she said carefully, "why did you tell me Robin was studying question of black holes?" The figure coughed. "Why, Mrs. Broadhead," Albert said, "I have been playing a recording prepared especially for you." "Not this time. Why did you volunteer this information other time?" Albert's expression cleared and he said humbly, "That directive did not come from my program, gospozha." "I thought not! You have been interacting with the psychoanalytic program!" "Yes, gospozha, as you programmed me to do." "And what was the purpose of this intervention from the Sigfrid von Shrink program?" "I cannot say for sure-but," he added hastily, "perhaps I can offer a guess. Perhaps it is that the Sigfrid estimates your husband should be more open with you." "That program is not charged with care of my mental health!" "No, gospozha, not with yours, but with your husband's. Gospozha, if you wish more information, let me suggest that you consult that program, not me." "I can do more than that!" she blazed. And so she could. She could speak three words-Daite gorod Polymat-and Albert, Harriet, Sigfrid von Shrink, every one of Robin's programs would be subsumed into the powerful program of her own, Polymath, the one she had used to write them in the first place, the overriding program that contained every instruction they owned. And then let them try cunning evasions on her! Then let them see if they could maintain the confidentiality of their memories! Then "God," Essie said aloud, "am actually planning to teach lesson to my own programs!" "Gospozha?" She caught her breath. It was almost a laugh, nearly a sob. "No," she said, "cancel above. I find no fault with your programming, Albert, nor with shrink's. If shrink program judges Robin should release internal tensions, I cannot overrule and will not pry. Further," she corrected herself fairly. The curious thing about Essie Lavorovna-Broadhead was that "fairness" meant something to her, even in dealing with her constructs. A program like Albert Einstein was large, complex, subtle, and powerful. Not even S. Ya. Lavorovna could write such a program alone; for that she needed Polymath. A program like Albert Einstein learned, and grew, and redefined its tasks as it went along. Not even its author could say why it gave one bit of information and not another. One could only observe that it was working, and judge it by how it carried out its orders. It was unfair to the program to "blame" it, and Essie could not be so unfair. But, as she moved restlessly among her pillows (twenty-two minutes left!) it came to her that the world was not entirely fair to her. Not fair at all! It was not fair that all these fairytale wonders should be pouring in upon the world-not now. It was not fair that these perils and perplexities should manifest themselves, not now, not while she might not live to see how they came out. Could Peter Herter be dealt with? Would the others of his party be saved? Could the lessons of the prayer fans and the explorers make it possible to do all the things Robin promised, feed the world, make all men well and happy, allow the human race to explore the universe? All these questions, and before this day's sun had set she might be dead and never to know the answers! It was not fair, any of it. And least fair was that if she died of this operation she would never know, truly, which way Robin would have chosen, if somehow his lost love could be found again. She became aware that time was passing. Albert sat patiently in the tank, moving only occasionally to suck his pipe or scratch under the hem of his floppy sweater-to remind her, that is, that he was still in standby mode. Essie's thrifty cybernetician's soul was indignantly ordering her to use the program or turn it off-what a shocking waste of machine time! But she hesitated. There were questions still to ask. At the door the nurse was looking in. "Good morning, Mrs. Broadhead," she said when she saw that Essie was wide awake. "Is it time?" Essie asked, her voice suddenly unsteady. "Oh, not for a few minutes yet. You can go on with your machine if you want to." Essie shook her head. "Is no point," she said and dismissed the program. It was a decision lightly taken. It did not occur to her that some of the unasked questions might be consequential. And when Albert Einstein was dismissed he did not allow himself to disintegrate at once. "The whole of anything is never told," said Henry James. Albert knew "Henry James" only as an address, the information behind which he had never had occasion to seek. But he understood the meaning of that law. He could never tell the whole of anything even to his master. He would fail in his programming if he tried. But what parts of the whole to select? At its lowest structural level, Albert's program was gated to pass items of a certain measured "importance" and reject others. Simple enough. But the program was redundant. Some items came to it through several gates, sometimes as many as hundreds of gates; and when some of the gates said "go" and others said "no go," what was a program to do? There were algorithms to test importance, but at some levels of complexity the algorithms taxed even the resources of sixty billion gigabits-or of a universe full of bits; Meyer and Stockmeyer had proved, long ago, that, regardless of computer power, problems existed which could not be solved in the life of the universe. Albert's problems were not quite that immense. But he could not find an algorithm to decide for him, for instance, whether he should bring up the puzzling implications of Mach's Principle as applied to Heechee history. Worse. He was a proprietary program. It would have been interesting to pass on his conjectures on the subject to a pure science research program. But that his basic programming did not permit. So Albert held himself together for nearly a millisecond, reconsidering his options. Should he, next time Robin summoned him, volunteer his misgivings about the potentially terrifying truth that lay behind Heechee Heaven? He reached no conclusion in all that long one thousandth of a second, and his parts were needed elsewhere. So Albert allowed himself to come apart. This part he poured into slow memory, that part into ongoing problems as needed, until all of Albert Einstein had soaked into the 6 x 10 bits, like water into sand, until not even a stain was left. Some of his routines joined with others in a simulated war game, in which Key West was invaded from Grand Cayman. Some turned up to assist the traffic-controller program at Dallas-Fort Worth, as Robin Broadhead's plane entered its landing pattern. Much, much later, some of him helped to monitor Essie's vital functions as Dr. Wilma Liederman began to cut. One little bit, hours after, helped to solve the mystery of the prayer fans. And the simplest, crudest, tiniest part of all stayed on to supervise the program that prepared Cajun coffee and beignets for Robin when he arrived, and to see that the house was clean for him. Sixty billion gigabits can do much. They even do windows. 13 At the Halfway Point To love someone is a grace. To marry someone is a contract. The part of me that loved Essie, was loving her wholeheartedly, sank in pain and terror when she relapsed, surged in fearful joy when she showed signs of recovering. I had plenty of occasion for both. Essie died twice in surgery before I could get home, and again, twelve days later, when they had to go in again. That last time they made her clinically dead on purpose. Stopped heart and breath, kept only the brain alive. And every time they reanimated her I was frightened to think she would live because if she lived it meant she might die one more time, and I could not stand it. But slowly, painfully, she began to gain weight, and Wilma told me the tide had turned, as when the spiral begins to glow in a Heechee ship at the halfway point and you know you're going to live through the trip. I spent all that time, weeks and weeks of it, hanging around the house, so that when Essie could see me I would be there. And all that time the part of me that had contracted to be married to her was resenting the bond, and wishing I were free. How do you account for that? That was a good occasion for guilt, and guilt is a feeling that comes readily to me-as my old psychoanalytic program used to tell me all the time. And when I went in to see Essie, looking like a mummy of herself, the joy and worry filled my heart and the guilt and resentment clogged my tongue. I would have given my life to make her well. But that did not seem a practical strategy, or at least I could not see any way to make that deal, and the other guilty and hostile part of me wanted to be free to dwell on lost Kiara, and whether somehow I might find her again. But she mended, Essie did. She mended fast. The sunken bags of flesh under her eyes filled to be only bruises. The tubes came out of her nostrils. She ate like a pig. Before my very eyes she was filling out, the bust beginning to swell, the hips regaining their power to startle. "My compliments to the doctor," I told Wilma Liederman when I caught her on her way in to see her patient. She said sourly, "Yes, she's doing fine." "I don't like the way you said that," I told her. "What's the matter?" She relented. "Nothing, really, Robin. All her tests are fine. She's in such a hurry, though!" "That's good, isn't it?'" "Up to a point it is. And now," she added, "I have to get in to see my patient. Who will be up and about any day now and, maybe, back to normal in a week or two." What good news that was! And how reluctantly I received it. I went through all those weeks with something hanging over me. Sometimes it seemed like doom, like old Peter Herter blackmailing the world and nothing the world could do to resist it, or like the Heechee stirring into anger as we invaded their complex and private worlds. Sometimes it seemed like golden gifts of opportunity, new technologies, new hopes, new wonders to explore and exploit. You would think that I would distinguish between hopes and worries, right? Wrong. Both scared the hell out of me. As good old Sigfrid used to tell me, I have a great talent not only for guilt but also for worry. And when you came right down to it, I had some fairly real things to worry about. Not just Essie. When you reach a certain age you have, it seems to me, a right to expect some parts of your life to stay stable. Like what, for instance? Like money, for instance. I was used to a lot of it, and now here was my lawyer program telling me that I had to watch my pennies. "But I promised Hanson Bover a million cash," I said, "and I'm going to pay it. Sell some stock." "I've sold stock, Robin!" He wasn't angry. He wasn't programmed to be able to be really angry, but he could be wretched and he was. "So sell some more. What's the best to get rid of?" "None of it is 'best,' Robin. The food mines're down because of the fire. The fish farms still haven't recovered from losing the fingerlings. A month or two from now..." "A month or two from now isn't when I want the money. Sell." And when I signed him off and called Bover up to find out where to send his million, he actually seemed surprised. "In view of Gateway Corp's action," he said, "I thought you'd call our arrangement off." "A deal is a deal," I said. "We can let the legalities hang. They don't mean much while Gateway has preempted me." He was suspicious immediately. What is it that I do that makes people suspicious of me when I am going miles out of my way to be fair?' "Why do you want to hold off on the legalities?" he demanded, rubbing the top of his head agitatedly-was it sunburned again? "I don't 'want' to," I said, "it just doesn't make any difference. As soon as you lift your injunction Gateway will drop theirs on me." Alongside Bover's scowling face, my secretary program's appeared. She looked like a cartoon of the Good Angel whispering into Bover's ear, but actually what she was saying was for me: "Sixty seconds until Mr. Herter's reminder," she said. I had forgotten that old Peter had given us another of his two hour notices. I said to Bover, "It's time to button up for Peter Herter's next jab," and hung up-I didn't really care if he remembered, I only wanted to terminate the conversation. Not much buttoning up was involved. It was thoughtful-no, it was orderly-of old Peter to warn us each time, and then to perform so punctually. But it mattered more to airline pilots and automobus's than to stay-at-homes like me. There was Essie, however. I looked in to make sure she was not actually being perfused or catheterized or fed. She wasn't. She was asleep-quite normally asleep, with her dark-gold hair spilling all around her, and gently snoring. And on the way back to my comfortable console chair I felt Peter in my mind. I had become quite a connoisseur of invasions of the mind. It wasn't any special skill. The whole human race had, over a dozen years, ever since the fool kid, Wan, began his trips to the Food Factory. His were the worst, because they lasted so long and because he shared his dreams with us. Dreams have power; dreams are a kind of released insanity. By contrast, the one light touch we'd had from Janine Herter was nothing, and Peter Herter's precise two-minute doses no worse than a traffic light you stop a minute, and wait impatiently until it is over, and then you go on your way. All I ever felt from Peter was the way he felt-sometimes the gut-griping of age, sometimes hunger or thirst, once the fading, angry sexual lust of an old man all by himself. As I sat down I remember telling myself that this time was nothing at all. More than anything else, it was like having a little dizzy spell, too much crouching in one position, when you stand up you have to pause a moment until it goes away. But it didn't go away. I felt the blurriness of seeing things with two sets of eyes at once, and the inarticulate anger and unhappiness of the old man-no words; just a sort of tone, as though someone were whispering what I could not quite hear. It kept on not going away. The blurriness increased. I began to feel detached and almost delirious. That second vision, that is never sharp and clear, began to show things I had never seen before. Not real things. Fantasy things. Women with beaks like birds of prey. Great glittering metal monsters rolling across the inside of my eyelids. Fantasies. Dreams. The two-minute measured dose of reminder had gone off track. The son of a bitch had fallen asleep in the cocoon. Thank God for the insomnia of old men! It didn't last eight hours, not much more than one. But they were sixty-odd unpleasant minutes. When I felt the unwanted dreams slide tracelessly out of my mind, and was sure they were gone, I ran to Essie's room. She was wide awake, leaning back against the pillows. "Am all right, Robin," she said at once. "Was an interesting dream. Nice change from my own." "I'll kill the old bastard," I said. Essie shook her head, grinning up at me. "Not practical," she said. Well, maybe it wasn't. But as soon as I had satisfied myself that Essie was all right, I called for Albert Einstein: "I want advice. Is there anything that can be done to stop Peter Herter?" He scratched his nose. "You mean by direct action, I assume. No, Robin. Not by any means available now." "I don't want to be told that! There must be something!" "Sure thing, Robin," he said slowly, "but I think you're asking the wrong program. Indirect measures might work. As I understand it, you have some legal questions unresolved. If you could resolve them, you might be able to meet Herter's demands and stop him that way." "I've tried that! It's the other way around, damn it! If I could get Herter to stop, then maybe I could get Gateway Corp to give me back control. Meanwhile he's screwing up everybody's mind, and I want it stopped! Isn't there some kind of interference we could broadcast?" Albert sucked his pipe. "I don't think so, Rob," he said at last. "I don't have a great deal to go on." That startled me. "You don't remember what it feels like?" "Robin," he said patiently, "I don't feel anything. It is important for you to remember that I am only a computer program. And not the right program, really, to discuss the exact nature of the signals from Mr. Herter-your psychoanalytic program might be more helpful. Analytically I know what happened-I have all the measurements of the radiation involved. Experientially, nothing. Machine intelligence is not affected. Every human being experienced something, I know because there are reports to say so. There is evidence that the larger-brained mammals-primates, dolphins, elephants-were also disturbed; and maybe other mammals were too, although the evidence is sketchy. But I have not experienced it directly.... As to broadcasting an interfering pattern, yes, perhaps that could be done. But what would be the effect, Robin? Bear in mind that the interfering signal would come from a nearby point, not one twenty-five light-days away; if Mr. Herter can cause some disorientation, what would a random signal do at close range?" "It would be bad, I guess." "Sure thing, Robin. Probably worse than you guess, but I could not say without experimentation. The subjects would have to be human beings, and such experiments I cannot undertake." Over my shoulder Essie's voice said proudly, "Yes, you exactly cannot, as who would know better than I?" She had come up behind me without a sound, barefoot in the thick rug. She wore a neck-to-ankle robe and her hair was done up in a turban. "Essie, what the hell are you doing out of bed?" I demanded. "My bed has become excessively tedious," she said, kneading my ear in her fingers, "especially occupied alone. Do you have plans for this evening, Robin? Because, if invited, I would like to share yours." "But..." I said, and, "Essie..." I said, and what I wanted to say was either "You shouldn't be doing this yet!" or "Not in front of the computer!" She didn't give me a chance to decide which. She leaned down to press her cheek against mine, perhaps so that I might feel how round and full it had once again become. "Robin," she said sunnily, "I am far more well than you believe. You may ask the doctor, if you wish. She will tell you how very rapidly I have healed." She turned her head to kiss me quickly and added, "I have some affairs of my own for the next few hours. Please continue chatting with your program until then. I am sure Albert has many interesting things to tell you, isn't that so, Albert?" "Sure thing, Mrs. Broadhead," the program agreed, puffing cheerfully on his pipe. "So, then. It's settled." She patted my cheek and turned away, and I have to say that as she walked back to her room she did not in the least look unwell. The robe was not tight, but it was shaped to her body, and the shape of her body was really fine. I could not believe that the wadding of bandage all along her left side was gone, but there was no sign of it. Behind me, my science program coughed. I turned back, and he was puffing on his pipe, his eyes twinkling. "Your wife is looking very well, Robin," he said, nodding judiciously. "Sometimes, Albert," I said, "I don't know just how anthropomorphic you are. Well. What very interesting things do you want to tell me about?" "Whatever you want to hear, Robin. Shall I continue on the subject of Peter Herter? There are some other possibilities, such as the abort mode. That is, setting aside for the moment the legal complications, it would be possible to command the shipboard computer, known as 'Vera', to explode the fuel tanks on the orbital craft." "Hell it would! We'd destroy the greatest treasure we've ever found!" "Sure thing, Robin, and it's even worse than that. The chance of an external explosion damaging the installation Mr. Herter is using is quite small. It might only anger him. Or strand him there, to do as he chooses, as long as he lives." "Forget it! Don't you have anything good to tell me about?" "As a matter of fact, Robin," he grinned, "I do. We've found our Rosetta stone." He shrank away to a dwindling spray of colored flecks and disappeared. As a luminous spindle-shaped mass of lavender color replaced him in the tank, he said, "That is the image of the beginning of a book." "It's blank!" "I haven't started it yet," he explained. The shape was taller than I, and about half as thick as it was tall. It began to shift before my eyes; the color thinned out until I could see through it clearly and then one, two, three dots began to appear inside it, points of bright red light that spun themselves out in a spiral. There was a sad chittering sound, like telemetry or like the amplified chirps of marmosets. Then the picture froze. The sound stopped. Albert's voice said: "I have stopped it at this point, Robin. It is probable that sound is language, but we have not yet been able to isolate semantic units from it. However, the 'text' is clear. There are one hundred thirty-seven of those points of light. Now watch while I run a few more seconds of the book." The spiral of 137 tiny stars doubled itself. Another coil of dots lifted itself from the original and floated to the top of the spindle, where it hung silently. The chitter of language began again and the original spiral expanded itself, while each of the dots began to trace a spiral of its own. When it was finished there was one large spiral, composed of 137 smaller spirals, each composed of 137 dots. Then the whole red pattern turned orange and it froze. "Do you want to try to interpret that, Robin?'" Albert's voice asked. "Well, I can't count that high. But it looks like 137 times 137, right?" "Sure thing, Robin. 137 squared, making 18,769 dots in all. Now watch." Short green lines slashed the spiral into ten segments. One of the segments lifted itself off, dropped to the bottom of the spindle and turned red again. "That's not exactly a tenth of the number, Robin," said Albert. "By counting you find that there are now 1840 dots at the bottom. I'll proceed." Once again, the central figure changed color, this time to yellow. "Notice the top figure." I looked closely, and saw that the first dot had turned orange, the third yellow. Then the central figure rotated itself on the vertical axis and spun out a three-D column of spirals, and Albert said, "We now have a total of 137 cubed dots in the ce
