Safe to breathe here. As he took a deep breath a brilliant flashlight suddenly came on, s.h.i.+ning blindingly in his face from only two feet away. "I have a gun pointed at you," said the precise voice of the blond short teener. "Turn left and walk ahead in the directions I tell you. I could kill you here, and no one would find your body, so try to keep my good will."

"Where is Carl Hodges?" George asked, walking with his hands up. The flashlight threw his shadow ahead of him big and wavering across the narrow walls.

"We're all going to be holing down together. Turn left here." The voice was odd.

George looked back and saw that the short teener was wearing a gas mask. As he took a breath to ask why, the white fog rolled down from a night-sky crevice above them. It smelled damp and slightly alcoholic.

"Keep moving," said the teener, gesturing with his gun. George

turned left, wondering what happened next when you breathed

that fog. A busy day, a busy night. An experience of symbolic insight was often reported by people who had been flattened by police anti-riot gas. What had the day meant? Why were such things happening?

Floating in white mist, George floated free of his body over the city and saw a vast spirit being of complex and bitter logic who brooded over the city and lived also in its future. George spoke to it, in thoughts that were not words. "Ahmed uses the world view of his grandmother, the gypsy. He believes that you are Fate. He believes you have intentions and plans."

It laughed and thought: The wheels of time grind tight. No room between gear and gear for change. Future exists, logical and unchangeable. No room for change in logic. When it adds up, it must arrive at the same concluding scene. The city is necessity. The future is built. The gears move us toward it. 1 am Fate.

George made a strange objecting thought. "The past can change. So everything that adds up from the past can change."

There was a wail from the atmosphere. The vast spirit that brooded over the city vanished, destroyed, dwindling to nowhere, uncreated, never true, like the Wicked Witch of the West when Dorothy poured a bucket of water over her, leaving behind the same dwindling wail. "But all my beautiful disasters, the logic, the logic . . .

"No arithmetic;" George said firmly. "If you can see the future, you can change it. If you can't see the past, it can change by itself and be anything. It won't add up the same twice."

All the crystallized visions of the city of the future shattered and dissolved into white fog, a creative fog that could be shaped to anything by thought. George stood at the center of creation and felt stubborn. They were tempting him again, trying to get him into the bureaucratic game of rules and unfreedom. "No," he said. "I won't fence anyone in with my idea. Let them choose their own past."

He came to consciousness lying on the floor in a small tight room with the blond kid sitting on a bed pointing a gun at him.

"They got Carl Hodges back," the kid said. "You ruined everything. Maybe you are a cop. I don't know. Maybe I should kill you."

"I just had a wild dream," George said, lifting his head, but not moving because he did not want to be shot. "I dreamed I talked to the Fate of New York City. And I told Fate that the future can change anytime, and the past can change anytime. In the beginning was the middle, I said. And Fate started crying and boohooing and vanished. I mean, no more Fate. Vanished."

There was a long pause while the short blond kid held the pistol pointed at George's face and stared at him over the top of it. The kid tried several tough faces, and then curiosity got the better of him. He was basically an intellectual, even though a young one, and curiosity meant more to him than love or hate. "What do you mean? The past is variable? You can change it?"

"I mean, we don't know what happened in the past exactly. It's gone anyhow. It's not real anymore. So we can say anything happened we want to have happened. If one past is going to make trouble, we can change it just by being dumb, and everything will straighten out. Like, for example, we just met, right now, right here, we just met. Nothing else happened."

"Oh." The kid put away his gun, thinking about that. "Glad to meet you. My name's Larry."

"My name's George." He arranged himself more comfortably on the floor, not making any sudden moves.

They had a long philosophical discussion, while Larry waited for the police outside to finish searching and go away. Sometimes Larry took the gun out and pointed it again, but usually they discussed things and exchanged stories without accepting any past.

Larry was serious and persuasive in trying to convince George that the world had too many technicians. "They don't know how to be human beings. They like to read about being Tarzan, or see old movies and imagine they are Humphrey Bogart and James Bond, but actually all they have the guts to do is read and study. They make money that way, and they make more gadgets and

they run computers that do all the thinking and take all the challenge and conquest out of life. And they give a pension to all the people who want to go out into the woods, or surf, instead of staying indoors pus.h.i.+ng b.u.t.tons, and they call the surfers and islanders and forestfarmers Free Loaders, and make sure they are sterilized and don't have children. That's genocide. They are killing off the real people. The race will be descended from those compulsive b.u.t.ton pushers, and forget how to live."

It was a good speech. George was uneasy, because it sounded right, and he was sure no man was smart enough to refute the killer, but he tried.

"Couldn't a guy who really wanted children earn enough money to get a breeding permit for himself and an operation for his wife?"

"There aren't that many jobs anymore. The jobs that are left are b.u.t.ton-pusher jobs, and you have to study for twenty years to learn to push the right b.u.t.ton. They're planning to sterilize everyone but b.u.t.ton pushers."

George had nothing to say. It made sense, but his own experience did not fit. "I'm not sterilized, Larry, and I'm a real dope. I didn't get past the sixth grade."

"When did your childhood support run out?"

"Last year."

"No more free food and housing. How about your family-they support you?"

"No family. Orphan. I got lots of good friends, but they all took their pensions and s.h.i.+pped out. Except one. He got a job."

"You didn't apply for the unemployable youth pension yet?"

"No. I wanted to stay around the city. I didn't want to be s.h.i.+pped out. I figured I could get a job."

"That's a laugh. Lots of luck in getting a job, George. How are you planning to eat?"

"Sometimes I help out around communes and share meals. Everyone usually likes me in the Brotherhood communes." George s.h.i.+fted positions uneasily on the floor and sat up. This was almost lying. He had a job now, but he wasn't going to talk about Rescue Squad, because Larry might call him a cop and try to shoot him. "But I don't b.u.m meals."

"When's the longest you've gone without meals?"

"I don't feel hungry much. I went two days without food once.

I'm healthy."'

The kid sat cross-legged on the bed and laughed. "Really healthy! You got muscles all over. You've got muscles from ear to ear. So you're trying to beat the system! It was built just to wipe out muscleheads like you. If you apply for welfare, they sterilize you. If you take your unemployable support pension, they sterilize you. If you are caught begging, they sterilize you. Money gets all you muscleheads sooner or later. It's going to get you too. I'll bet-' when you are hungry you think of the bottle of wine and the big free meal at the sterility clinic. You think of the chance of winning the million dollar sweepstakes if the operation gives you the right tattoo number, don't you?"

George didn't answer.

"Maybe you don't know it, but your unemployable pension is piling up, half saved for every week you don't claim it. You've been avoiding it a year almost? When it piles high enough, you'll go in and claim your money and let them sterilize you and s.h.i.+p you out to the boondocks, like everyone else."

"Not me."

"Why not?"

George didn't answer. After a while he said, "Are you going to let them sterilize you?"

Larry laughed again. He had a fox face and big ears. "Not likely. There are lots of ways for a smart guy to beat the system. My descendants are going to be there the year the sun runs down and we hook drives to Earth and cruise away looking for a new sun. My descendants are going to surf light waves in s.p.a.ce. n.o.body going to wipe me out, and n.o.body's going to make them into b.u.t.ton pushers."

"Okay, I see it." George got up and paced, two steps one way,

two steps the other way in the narrow room. "Who are you working for, Larry? Who are you crying over? People who let themselves be bribed into cutting off their descendants? They're different from you. Do they have guts enough to bother with? Are they worth getting your brain wiped in a court of law? You're right about history, I guess. I'm the kind of guy the techs are trying to get rid of. You're a tech type of guy yourself. Why don't you be a tech and forget about making trouble?"

At the end of the room, faced away from Larry, George stopped and stared at the wall. His fists clenched. "Kid, do you know what kind of trouble you make?"

"I see it on television," Larry said.

"Those are real people you killed." George still stared at the wall: "This afternoon I was giving artificial respiration to a girl. She was bleeding from the eyes." His voice knotted up. Big muscles bulged on-his arms and his fists whitened as he tried to talk. "She was dead, they told me. She looked all right, except for her eyes. I guess because I'm stupid." He turned and his eyes glittered with tears and with a kind of madness. He glanced around the small room looking for a thing to use for a weapon.

Larry took out his gun and pointed it at George, hastily getting off the bed. "Oh oh, the past is real again. Time for me to leave!" Holding the gun pointed steadily and carefully at George's face, he used his other hand to put on black goggles and slung the gas mask around his neck. "Hold still, George, you don't want a hole through your face. If you fight me, who are you working for? Not your kind of people. Think, man." He backed to the door. George turned, still facing him, his big hands away from his sides and ready, his eyes glittering with a mindless alertness.

Larry backed into the dark hall. "Don't follow. You don't want to follow me. This gun has infrasights, shoots in the dark. If you stick your head out the door, I might shoot it off. Just stand there for ten minutes and don't make any trouble. The gun is silenced. If I have to shoot you, you don't get any medal for being a dead hero. No one would know."

The short teener backed down the dark corridor and was gone. George still stood crouched, but he shook his head, like a man trying to shake off something that had fallen over his eyes.

He heard Larry b.u.mp into something a long way down the corridor.

"I would know," a voice said from the ceiling. Ahmed let himself down from a hole in the ceiling, hung by both long arms and then dropped, landing catlike and silent. He was tall and sooty and filthy and covered with cobwebs. lie grinned and his teeth were white in a very dark face. "You just missed a medal for being a dead hero. I thought you were going to try to kill him."

He twiddled the dial of his wrist radio, plugged an earphone into one ear and spoke into the wrist radio. "Flushed one. He's heading west on a cellar corridor from the center, wearing a gas mask and infragoggles, armed and dangerous. Lie's the kingpin, so try hard, buddies."

George sat down on the edge of the bunk, sweating. "I get too mad sometimes. I almost did try to kill him. What he said was probably right. What he said."
