"Mm-hmm. Thought it would be easier to get it done all at once than take you through it step by step.

Maybe that way you will remember what you wrote." He tried to be more casual than he felt. "Come over this afternoon and I'll give you a first run-through of how it works."

"You bet. See you there."

The day dragged by. It was Dolly's afternoon to play bridge and the house would be empty.

"This is the final surgery," Snaresbrook dictated quietly. "The implants are all in place. The CPU put into position. The regrowth of new nerve connections to the damaged portions of the cortex is almost completed.

The replacements for the corpus callosum connections are being stimulated. The fiber-optic interfaces between the chips have been installed, the last of the intracranial procedures. The meningeal tissues have been repaired or replaced and I am now coating the edges of the section of bone that was removed to give access to the brain.

This will grow and seal the section of skull into place. The procedure now begins."

She did not add her silent thoughts that this was just the end of the surgical procedures. But the new and untried procedures that would hopefully restore the connections inside Brian's brain were only in their opening stages. New, unproven-would they work?

Stop thinking about it. Complete this and move on.

It was a muggy and torrid July afternoon when Brian finally got away from the computer lab. He had worked out what he hoped would be an improvement on LAMA, and AI programming language that his father had helped to develop. If he was right the cross-linking nemes of the CYC information nets could be speeded up by a factor of 10. But his new technique had to be tested and this would have taken days to work through on his own computer-so he managed to borrow some time on the Cray 5 and if all went well he should get some results by morning. Which meant there wasn't much else he could do until then.

And there was a good chance Kim might be waiting for him at home. He walked faster now and his sweat- soaked shut stuck to his skin. She had no classes this afternoon so she might come over for what she called tutoring. Yes, there would also be some tutoring because she really needed it. She was cutting classes now and ignoring lectures because she knew that he would be there to tell her what to do before the exams. She really hated the school work and was always happy to find something better to do. Brian slowed down when he realized he was gasping for breath. Easy did it in this heat or he would get back dead.

The cool air puffed out and embraced when he opened the front door.

"Anyone home?" he called out, but silence was his answer. Then he heard the music playing, smiled and pushed open the half-closed door to his room.

"I called-you didn't hear me."

The stereo was on, switched to the Mississippi soul food station, but the room was empty. His bed was rumpled and his pillows pushed into a backrest the way she liked them. He looked around for a note, Kim still wrote them, never thinking to access the network, found nothing. He turned off the music and the only sound was the whir of the fan on the computer. It muttered to itself while it accessed a disk. The kitchen-that was it.

Kim was the world's best nibbler. The glass and dirty dish in the sink proved it. But she wasn't there.

Nor did she answer her phone. He searched more carefully a second time; she had left him handwritten messages more than once, probably the only person in computer-happy UFE that did his anymore, but still couldn't find any note. Maybe she actually broke a long-standing dislike and actually left a message in the computer. He called up his communication program but there was nothing there.

Mysterious-and he was beginning to get worried. Could something have happened to her? The front door had been closed, but not locked. It usually wasn't locked except at night; the university was a cutoff and safe place.

Except no place was really safe. Hadn't they just caught the drug smugglers a few miles down the coast? The isolated rigs of UFE might be the ideal spot for another try. A sudden sound caught his attention as the computer whirred and a drive light came on.

Of course! This program had been running for a couple of days and the machine was in verbal command mode, left that way most of the time even when he was entering data from the keyboard, programmed to record any words or sounds and respond if necessary. There would be a record of her voice.

It was easy enough to find. He jumped back, turned on the speakers-and heard himself snoring. Jumped forward and heard the morning news he had listened to while dressing. Forward and forward-and there she was! Humming along with the radio. Nothing wrong here; he skipped forward, the sound track making Donald Duck sounds-then stopped when he heard her voice. Talking on the phone.

"Sure, yes. If you insist. Soon. Right. Bye."

Only one side of the conversation: he had never considered putting a tap on his phone. He did a high-speed forward, heard something, backtracked. It was Kim laughing.

Then a male voice said, "Do that again and there's no stopping me."

Brian rested his head on his fingertips, bent over the computer, the speaker close to his ear. Listening to what could only have been sounds of lovemaking. In his bed. With someone else. Listening to every humiliating sound and gasp, to her mounting little cries of delight.

Listened until it was all over. They were talking quietly but he listened no longer. The voices were nothing, meant nothing.

Finished. Through. The blood hammered in his temples as he was possessed by a terrible sense of betrayal. He had meant absolutely nothing to her-except maybe as an unpaid tutor, or maybe that was how she paid for his lessons! She had never been serious about him, never felt what he felt. What he realized shamefully now was that his puppy love had been completely one-sided. She hadn't shared it-probably didn't even know his overwhelming and consuming feelings for her. His fingers were trembling with rage, mortification, as he wiped the program and the voices of betrayal, struck out the file, deleted it. Then formatted tracks over it so it could never be restored. More destruction. He sought out every piece of work he had done for her and wiped the disk clean. Wiped out a com file of messages from her. His hands were shaking and there were tears of rage in his eyes. Love turned to anger, attraction to betrayal. His hands shook as he seized the keyboard, began to lift it to throw at the screen.

This was crazy. He dropped it and rushed from the room banged down the hall into the kitchen, stood in the doorway, fists clenched, shaking with conflicting emotions. The rack of knives was before him on the counter and he pulled out the largest, tested the edge with his thumb, longed to plunge it into her. Again and again.

Kill her? What was he thinking about? Did simple, rutting emotions control his life? What had happened to logic and intelligence? His hands were still shaking as he slid the knife back into the slot. He stood at the sink staring unseeingly out of the window.

You have a brain, Brian. Use it. Or let your emotions run your life. Kill her, get revenge, go to jail for murder. Not the world's greatest idea, really. What is happening? How come emotion has taken the place of intelligent thought?

A subunit had taken control, that was what had happened. Think of the society of the mind and how it works. The mind is divided into many subunits, subunits with absolutely no intelligence of their own. What was the example his father had used when he explained it? Driving a car. A subunit of the mind can drive the car while the conscious mind is occupied with other things. Turning back control only when something unusual happened. The society of mind usually worked in a state of cooperation between all of its units. Now one stupid subunit had taken over and was controlling everything. One dumb, irrational subunit of infatuation-with gonads for brains and involved only with betrayal and jealousy and rage. Is this what he wanted to control his life?

"Hell, no!" He opened the refrigerator and took out a can of soda, popped the seal, drank half of it in one long chugalug. Much calmer and more rational now. He knew what was happening, one part of his brain had taken over and was calling all the shots and suppressing everything else. There was no such thing as a central me, though it was easy to believe that there was. The more he had studied the operation of intelligence, the more he had come to believe that each person was sort of a committee. The brain was made up of a lot of little subanimals-protospecialists, that's what they were called.

The hunger-animal took over when looking for food. Or the fear-animal when there was trouble looming. And every night the sleep-animal took its place. It was King Solomon's ring. All the machinery that Lorenz and Tinbergen had discovered. Those intricate networks of brain centers for hunger, sex, defense that had taken hundreds of millions of years to evolve. Not only in reptiles, birds and fish-but in parts of his own brain.

And now his own internal sex-animal was chomping and salivating and taking over. A primitive agency way down in the brain stem-and he had to fight it!

"That's not me!" he shouted out loud, slamming his fist onto the table so hard it hurt. "Not the whole me. Just a singularly stupid but powerful part. Balls galore!"

He was more than a rutting animal. He had intelligence-so why couldn't he use it? How could he let a stupid subunit take control? Where was the mental manager that should have evaluated it and put it into proper perspective and place?

He took the can of soda with him, sipping at it slowly. Sat in front of his computer and opened a new file labeled SELF CONTROL, then leaned back and thought about what came next.

Most mental processes work unconsciously, because most subunits of his mind had to become autonomous-as separate as his hands and feet-in order to work efficiently.

When he had learned to walk as a baby he must have done it badly at first, stumbling and falling, then gradually improving by learning from mistakes. The old subunits for not-good walking must slowly have been replaced or suppressed by new agents for good-walking agents that worked more automatically, with less need for reflective thinking. So many agents, he thought, to be controlled by what? Right now, they seemed to be quite out of control. It was time for him to take them in charge; he must exercise more self-control. It was time that he, himself, must decide which of those subunits should be engaged. That mysterious, separate He, must be the manager, the central control that would correspond to the essence of Brian's own consciousness.

"Those stupid AI programs could sure use a managing machine like that," he said, then choked on the soda.

Was it that simple? Was this the missing element that would pull together all the separate pieces? The AI research labs were filling up with so many interesting systems these days at universities like Amherst, Northwestern, and Kyushu Institute of Technology. Rule-based logic systems, story-based language understanders, neural- network learning systems, each solving its own kind of problem in its own way. Some could play chess, some could control mechanical arms and fingers, some could plan financial investments. All separate, all working by themselves-but none of them seemed to really think. Because nobody knew how to get all those useful parts to work together. What artificial intelligence needed was something like that internal he. Some sort of central Managing Machine to tie all the subunits into a single working unit.

It couldn't be that simple. There can't be any such he in charge-because the mind doesn't contain any real people, only a lot of subunits. Therefore, that he could not be any single thing-because no single thing could be smart enough. So that he must itself be some sort of illusion created by the activity of yet another society composed of subunits. Otherwise there would still be something missing, something to manage that Manager.

"Not good enough. I haven't got it quite right yet. It will need a lot more working out."

He saved the file with his thoughts-then noticed that there was one KIM file left on disk. The term paper for Betser. She had a copy of it-but she would never understand it, much less explain it when she was queried.

Maybe he should save this one as well, after all she had been responsible for his idea about a managing program.

No way! He hit delete and it vanished with all the rest.

The very last thing he did was put a lock on the computer so it would not accept calls from her phone. But this wasn't good enough-she could still call from a public phone. He added a program that would turn away all incoming calls, no calls now or forever from anyone.

In the end he sat there tired and dry-eyed. Betrayed in every way.

Nothing like this was ever going to happen to him again. No one was ever going to get close enough to him to hurt him. He was going to think about his AI managing program and see if he could get it to work and forget about her. Forget about girls. Something like this was never going to happen to him again. Ever.

Coronado April 2, 2023

The helicopter came in over the bay, past the bridge that connected the hooked peninsula of Coronado to San Diego. The roads below were sealed tight by security: the copter was not only the safest but was the fastest way in and out of the base. It swooped low over the gray shapes of the mothball fleet, quietly rusting into extinction since the end of the Second World War. They dropped down to the HQ helipad, dust clouds roiling out, and saw a stretched limo pull up.

"This seems like an awful lot of trouble to go to for a meeting," Erin Snaresbrook snapped. "Some of us have work to do. This is totally ridiculous-when we could have had a teleconference."

"All of us have work to do, Doctor, all of us," Benicoff said. "You have only yourself to blame-this meeting was your idea. You must have realized that this was the only way that we could guarantee security."

"A progress report, that was all that I said." She raised her hand before Benicoff could speak. "I know. I hear the arguments. It is far safer here. The disappearances, the thefts, assassination attempt. It's just that I hate these infernal awful choppers. They are the most dangerous form of transportation ever invented. One of them fell off the Pan Am Building, you're too young to remember, dropped right into Forty-second Street.

They are death traps."

They drove into an underground entrance to the headquarters building. Past marine sentries, guards and locked gates, TV cameras and all the security apparatus so adored by the military. One last guarded door admitted them to a conference room with a panoramic view of the bay and Point Loma. An aircraft carrier was just coming in from the open sea. In front of the window at least a dozen dark-suited civilians and uniformed officers were gathered around the teak table.

"Is this room secure?" Snaresbrook whispered.

"You're being facetious, Doctor," Benicoff whispered back. "That window will stop a thirty-inch naval shell."

Erin turned to look at it, then caught Benicoff's smile. Like her, he was joking to relax the tension.

"Sit down," General Schorcht ordered, his usual charming self. His introductions were equally succinct.

"Dr. Snaresbrook is on the left. With her is Mr. Benicoff, whom you have met before and who is in charge of the ongoing Megalobe investigation."

"And who are all these people?" Erin Snaresbrook asked sweetly. General Schorcht ignored her.

"You have a report to make, Doctor. Let's have it."

The silence lengthened, the General and the surgeon radiating cold hatred at each other. Benicoff broke in, not wanting the situation to decay any further.

"I called this meeting because it appears that the operations undertaken by Dr. Snaresbrook have now reached an important and most vital stage. Since the rest of our investigation is stalled, I feel that everything now depends on Dr. Snaresbrook. She had been a pillar of strength, our only hope in this disastrous matter. And she seems to have worked a miracle. She will now bring us up to date. If you please, Doctor." Slightly mollified, still very angry, the surgeon shrugged and decided that she had had enough of the petty feuding. She spoke calmly and quiet ly.

"I am now approaching the end of the basic surgery on the patient. The superficial damage caused by the bullet has had a satisfactory resolution. The more important and vital deep repairs of the nerve bundles in the cortex have been completed. The film implants were successful and the connections have been made by the inbuilt computer.

Gross surgery is no longer called for. The skull has been closed."

"You have succeeded. The patient will talk..."

"I will have no interruptions. From anyone. When I have finished my description of what has been done and what my prognosis is I will then answer any questions."

Snaresbrook was silent for a moment. So was General Schorcht, radiating pure hatred. She smiled demurely, then went on.

"I may have failed completely. If I have, that is the end of it. I'll not open his head again. I want to tell you strongly that there is always a chance of this. Everything I have done is still experimental-which is why I make no promises. But I will tell you what I hope will happen. If I have succeeded the patient will regain consciousness and should be able to talk. But I doubt if I will be talking to the man who was shot. He will not remember any of his life as an adult. If my procedures succeed, if he regains consciousness, it will be as a child."

She ignored the murmur of dismay, waited until it died down before she continued.

"If this is what happens I will be very pleased. It will mean that the procedure has succeeded. That will be the first step. If it goes as planned I must then proceed with additional input and communication in the hopes that his memories will be brought forward to the period in time when the assault occurred. Questions?"

Benicoff got in first with the question so vital to him. "You hope to bring his memory right up to the day the assault occurred?"

"That may indeed be possible."

"Will he remember what happened? Will he tell us who did it?"

"No, that is impossible." Snaresbrook waited until the reactions had died away before she spoke again. "You must understand that there are two kinds of memory, long-term and short-term. Long-term memories last for years, usually for an entire lifetime. Short-term is what happens to us in real time, details of a conversation we might be hearing, a book that we are reading. Most short-term memories simply fade away in a few seconds, or minutes. But some parts of short-term memories, if they are important enough, will eventually become long-term memory. But only after about a half an hour. It takes the brain that much time to process and store it. This is demonstrated in what is known as posttrauma shock. Victims of car accidents, for instance, can remember nothing of the accident if they were rendered unconscious at the time. Their short-term memory never became long-term memory."

General Schorcht's cold voice cut through the other voices and questions.

"If there is no chance of your succeeding in this dubious medical procedure why did you undertake it in the first place?"

Erin Snaresbrook had her fill of insults. Her cheeks flushed and she started to rise. Benicoff was on his feet first.

"May I remind everyone here that I am in charge of this ongoing invest igation. At great personal sacrifice Dr. Snaresbrook volunteered to help us. Her work is all that we have. Though there have been deaths already, and the pat ient may very well die as well, it is the investigat ion that is of paramount importance.

Brian Delaney may not reveal the killers-but he can show us how to build his artificial intelligence, which is what this entire matter is all about."

He sat down slowly and turned in his chair. "Dr. Snaresbrook, will you be kind enough to tell us what procedures are still to come?"

"Yes, of course. As you know I have left a number of surgical implants within the patient's brain. They consist of various kinds of computers connected by microscopic terminals to the brain's nerve fibers.

Controlled measures of chemicals can be released through these. By combining this with a carefully monitored variety of stimuli, I hope he will soon learn how to access more of his later but now inaccessible memories. When these are integrated he should have a functional mind once again.

"There may be gaps-but he will not be aware of them. What I hope he will be aware of and remember is all of the work he did in developing his AI. So that he can rebuild it and make it function.

"I will of course use more than chemicals. I have also implanted computer film chips that will interface directly with nerve endings. On these chips are embryonic brain cells that can be induced to grow in various ways. They can be kept dormant as long as I want, waiting for an opportunity to make the correct connections. When they are activated each one will be tested. The ones that end up wrong will be disconnected so that only the successful will remain act ive. This can all be done by opening microscopic chemical holes implanted in the chips. Either a connection will be made-or a tiny package of neurotoxins will destroy the cell."

"I have a question," one of the men said.

"Of course."

"Are you telling us that you are installing a machine-mind interface inside that boy's skull?"

"I am-and I don't know why you sound so shocked. This kind of thing has been going on for many years now. Why, even in the last century we were hooking up neural connections in the ear to cure deafness. Many times in recent years we have been able to use nerve impulses from the spinal cord to activate prosthetic legs.

Connecting to the brain itself was a logical next step."

"When will we be able to talk to Mr. Delaney?" Schorcht snapped.

"Perhaps never." Dr. Snaresbrook stood up. "You have my report. Make of it what you will. I am doing my very best, with still-experimental techniques, to rebuild that shattered mind. Trust me. If I succeed you will be the first to know."

She ignored the voices, the questions, turned and left the room.
