MYIILYN TEBENS was not a man of action. He told himself that as an excuse, since now, leaving the spaceport, he found his mind paralyzed.

He had to pick his pace carefully. Not too slowly, or he would seem to be dawdling. Not too quickly, or he would seem to be running. Just briskly, as a patroller would walk, a patroller who was about his business and ready to enter his ground-car.

If only he could enter a ground-car! Driving one, unfortunately, did not come within the education of a Florinian, not even a Florinian Townman, so he tried to think as he walked and could not. He needed silence and leisure.

And he felt almost too weak to walk. He might not be a man of action but he had acted quickly now for a day and a night and part of another day. It had used up his lifetime's supply of nerve.

Yet he dared not stop.

If it were night he might have had a few hours to think. But it was early afternoon.

If he could drive a ground-car he could put the miles between himself and the City. Just long enough to think a bit before deciding on the next step. But he had only his legs.

If he could think. That was it. If he could think. If he could suspend all motion, all action. If he could catch the universe between instants of time, order it to halt, while he thought things through. There must be some way.

He plunged into the welcome shade of Lower City. He walked stiffly, as he had seen the patrollers walk. He swung his shock stick in a firm grip. The streets were bare. The natives were huddling in their shacks. So much the better.

The Townman chose his house carefully. It would be best to choose one of the better ones, one with patches of colored plastic briquets and polarized glass in the windows. The lower orders were sullen. They had less to lose. An "upper man" would be falling over himself to help.

He walked up a short path to such a house. It was set back from the street, another sign of affluence. He knew he would have no need of pounding the door or breaking it in. There had been a noticeable movement at one window as he walked up the ramp. (How generations of necessity enabled a Florinian to smell the approach of a patroller.) The door would open.

It did open.

A young girl opened it, her eyes white-rimmed circles. She was gawky in a dress whose frills showed a determined effort on the part of her parents to uphold their status as something more that the ordinary run of "Florinian trash." She stood aside to let him pass, her breath coming quickly between parted lips.

The Townman motioned to her to shut the door. "Is your f ather here, girl?"

She screamed, "Pa!" then gasped, "Yes, sir!"

"Pa" was moving in apologetically from anothei~ room. He came slowly. It was no news to him that a patroller was at the door. It was simply safer to let a young girl admit him. She was less apt to be knocked down out of hand than he himself was, if the patroller happened to be angry.

"Your name?" asked the Townman.

"Jacof, if it please you, sir."

The Townman's uniform had a thin-sheeted notebook in one of its pockets. The Townman opened it, studied it briefly, made a crisp check mark and said, "Jacof! Yes! I want to see every member of the household. Quickly!"

If he could have found room for any emotion but one of hopeless oppression, Terens would almost have enjoyed himself. He was not immune to the seductive pleasures of authority.

They filed in. A thin woman, worried, a child of about two years wriggling in her arms. Then the girl who had admitted him and a younger brother.

"That's all?"

"Everyone, sir," said Jacof humbly.

"Can I tend the baby?" asked the woman anxiously. "It's her nap time. I was putting her to bed." She held the young child out as though the sight of young innocence might melt a patroller's heart.

The Townman did not look at her. A patroller, he imagined, would not have, and he was a patroller. He said, "Put it down and give it a sugar sucker to keep it quiet. Now, you! Jacof!"

"Yes, sir."

"You're a responsible boy, aren't you?" A native of whatever age was, of course, a "boy."

"Yes, sir." Jacof's eyes brightened and his shoulders lifted a trifle. "I'm a clerk in the food-processing center. I've had mathematics, long division. I can do logarithms."

Yes, the Townman thought, they've shown you how to use a table of logarithms and taught you how to pronounce the word.

He knew the type. The man would be prouder of his logarithms than a Squireling of his yacht. The polaroid in his windows was the consequence of his logarithms and the tinted briquets advertised his long division. His contempt for the uneducated native would be equal to that of the average Squire for all natives and his hatred would be more intense since he had to live among them and was taken for one of them by his betters.

"You believe in the law, don't you, boy, and in the good Squires?" The Towuman maintained the impressive fiction of consulting his notebook.

"My husband is a good man," burst in the woman volubly. "He hasn't ever been in trouble. He doesn't associate with trash. And I don't. No more do the children. We always-"

Terens waved her down. "Yes. Yes. Now look, boy, I want you to sit right here and do what I say. I want a list of everyone you know about on this block. Names, addresses, what they do, and what kind of boys they are. Especially the last. If there's one of these troublemakers, I want to know. We're going to clean up. Understand?"

"Yes, sir. Yes, sir. There's Husting first of all. He's down the block a way. He-"

"Not like that, boy. Get him a piece of paper, you. Now you sit there and write it all down. Every bit. Write it slowly because I can't read native chicken tracks,"

"I have a trained writing hand, sir."

"Let's see it, then."

Jacof bent to his task, hand moving slowly. His wife looked over his shoulder.

Terens spoke to the girl who had let him in. "Go to the window and let me know if any other patrollers come this way. I'll want to speak to them, Don't you call them. Just tell me."

And then, finally, he could relax. He had made a momentarily

• secure niche for himself in the midst of danger.

Except for the noisy sucking of the baby in the corner, there was reasonable silence. He would be warned of the enemy's approach in time for a fighting chance at escape.

Now he could think.

In the first place, his role as patroller was about over. There were undoubtedly road blocks at all possible exits from the town, and they knew he could use no means of transportation more complicated than a diamagnetic scooter. It would not be long before it would dawn on the search-rusty patrollers that only by a systematic quartering of the town, block by block and house by house, could they be sure of their man.

When they finally decided that, they would undoubtedly start at the outskirts and work inward. If so, this house would be among the first to be entered, so his time was particularly limited.

Until now, despite its black and silver conspicuousness, the patroller uniform had been useful. The natives themselves had not questioned it. They had not stopped to see his pale Floninian face; they had not studied his appearance. The uniform had been enough.

Before long the pursuing hounds would find that fact dawning upon them. It would occur to them to broadcast instructions to all natives to hold any patroller unable to show proper identification, particularly one with a white skin and sandy hair. Temporary identifications would be passed out to all legitimate patrollers. Rewards would be offered. Perhaps only one native in a hundred would be courageous enough to tackle the uniform no

matter how patently false the occupant was. One in a hundred would be enough.

So he would have to stop being a patroller.

That was one thing. Now another. He would be safe nowhere on Florina from now on. Killing a patroller was the ultimate crime and in fifty years, if he could elude capture so long, the chase would remain hot. So he would have to leave Florina.

How?

Well, he gave himself one more day of life. This was a generous estimate. It assumed the patrollers to be at maximum stupidity and himself in a state of maximum luck.

In one way this was an advantage. A mere twenty-four hours of life was not much to risk. It meant he could take chances no sane man could possibly take.

He stood up.

Jacof looked up from his paper. "I'm not quite done, sir. I'm writing very carefully."

"Let me see what you have written."

He looked at the paper handed him and said, "It is enough. If other patrollers should come, don't waste their time saying that you have already made a list. They are in a hurry and may have other tasks for you. Just do as they say. Are there any coming now?"

The girl at the window said, "No, sir. Shall I go out in the street and look?"

"It's not necessary. Let's see now. Where is the nearest elevator?"

"It's about a quarter of a mile to the left, sir, as you leave the house. You can-"

"Yes, yes. Let me out."

A squad of patrollers turned into the street just as the door of the elevator ground into place behind the Townman. He could feel his heart pound. The systematic search was probably starting, and they were at his heels.

A minute later, heartbeat still drumming, he stepped out of the elevator into Upper City. There would be no cover here. No pillars. No cementalloy hiding him from above.

He felt like a moving black dot among the glare of the garish buildings. He felt visible for two miles on every side and for five miles up in the sky. There seemed to be large arrows pointing to him.

There were no patrollers in view. The Squires who passed looked through him. If a patroller was an object of fear to a Florinian, he was an object of nothing-at-all to a Squire. If anything would save him, that would.

He had a vague notion of the geography of Upper City. Somewhere in this section was City Park. The most logical step would have been to ask directions, the next most logical to enter any moderately tall building and look out from several of the upperstory terraces. The first alternative was impossible. No patroller could possibly need directions. The second was too risky. Inside a building, a patroller would be more conspicuous. Too conspicuous.
