save his neck in an emergency.

He turned to the problem of getting across the open field. He had little fear of being picked up by radiation detectors, thanks to his absorber. But direct contact could give him away. But most of those had to be buried. That meant that he could keep close to the bushes and not have to worry. The roots of the bushes fouled up the detection instruments if they got to them. He made his way, judging each step before he took it and at last stood by the door.

It was dark by then. He could see the stars in the clear darkness of the sky. They seemed somehow brighter than they had before. Nelson fished through his pack until he felt the familiar shape of the gadget he wanted. It was smaller, more compact than the one he had used to get over the fence; but it was more complex. He felt along the door frame for the alarm trip and found it. He placed the gadget there and switched it on. There was a short, low, buzzing sound as the gadget did its job and Nelson glanced around nervously, in fear it had been heard. The door's lock clunked back and Nelson released air from his lungs. He pushed the door open and found himself in darkness.

He was in a corridor with doors facing off from it. He could see light coming under two of the doors, meaning patrolmen behind them. He moved cautiously by the two doors, almost opposite each other, to a door at the end of the corridor. He grasped the handle and opened the door, realizing too late that the door should have been locked.

But by that time the door was open. His hand darted to his holstered furnace beamer and unlocked the safety. It was almost pitch dark in the room but he heard the room's occupant turning over on the bunk and mumble low, incoherently, in his sleep. Nelson waited a minute but the man didn't wake up.

Nelson closed the door.

He tried another door; this time, one that was locked. He had no trouble forcing the lock pattern; less than a minute later he was inside, with the door shut behind him. He took out a flashlight.

This was the storeroom, all right. It was piled with boxes mostly unopened. Nelson read the labels on the boxes and opened those which contained food he needed and supplies. He found another pack in an opened box in one corner and began outfitting it like his own. Or as nearly like his own as possible; he know that he could never duplicate or replace the gadgets Gardner had designed, and in a way he was bitter about it. He found the ammunition stores and took as many capsules for the furnace beamers as he could carry. He went to the door but slipped the furnace beamer out of his holster before opening the door.

The corridor was still dark. He stepped into it, alert for any sound or movement that might mean danger or herald discovery. His nervousness had given way to cool, detached determination. He almost made it to the door before he heard the footsteps.

His reaction was unconscious and reflexive. He turned, leveling his gun. He had passed the two doors light had shown under. One of them was opening and Nelson saw the shadow of the man who had opened it; then the man. The man saw Nelson at about the same time and stood gaping at him. Without realizing that he had fired, Nelson felt the recoil of the gun; the roar of the beam against the close walls hurt his ears, parts of the wall blistered and buckled, other parts of it charred black, some parts vaporizing in thin patches. The patrolman had flared instantly, never really knowing what had hit him. Smoke and heavy odors filled the corridor as Nelson slid out into the open. The patrol depots were fireproof, but the area Nelson had blasted would be far to hot to pass through for the rest of the night.

Nelson toned down the volume of his beamer and fired at a fence post. The tough plastic burst into splinters with a sudden explosion. A snapping wire whipped to within inches of Nelson's face but he didn't have to think about it. He was running up the hillside a short while later—he had lost track of time as such—hoping that Glynnis would use her gun if any patrolmen were following him.

He reached the hilltop in darkness, afraid to use his flashlight. Suddenly, he stumbled; was falling over something soft, like an animal or a man. Cursing low and involuntarily, he managed to roll over so that he fell on his back. He saw the form, a patch of irregular blackness in the darkness around him and knew it for a body. He got to his feet glancing around, not knowing what this meant. He bent over the form, keeping the furnace beam's muzzle only a few inches from it, but too far back to be grabbed suddenly. He couldn't see the man's clothing very plainly but he could tell it was a patrolman's uniform. Nelson reached down to feel for a heartbeat and drew his hand away sticky with what he knew must be blood. Nelson was shaken for a moment; but he put aside the strange kinship he so often felt for patrolmen because they were also wakers and drew back, peering round into the darkness, pretty certain that he knew what had happened to this patrolman.

He pushed himself erect and turned to see Glynnis, a dark figure but obviously her, standing near a clump of trees a few feet off.

"You move quiet as a cat," he said. "You do this?"

"Uh-huh." She came forward and stared down at the corpse. Nelson was glad he couldn't see her face in the darkness. "There were two of them. They split up and I followed after this one and came up behind him. I slit his throat. Then I went and got the other one the same way."

And it had been so simple, thought Nelson. He handed Glynnis the extra pack. "Take this." She accepted it wordlessly and slipped her arms into the straps. "Oh," he added, as an afterthought. "Let me show you something." He reached into the pack and drew out a knife. A good one with a long plasteel blade that would not chip or corrode like hers. He handed it to her and imagined her smiling face in the darkness.

"It doesn't feel like metal," she said, after she had taken the knife from its scabbard.

"It isn't. It's a kind of plastic, stronger than most metals. Do you like it?" He was wasting time, he knew, and he cursed himself for it. But it didn't matter.

"It's real nice," she answered.

"I'm glad you like it," he said, taking her elbow in his hand. "We'd better go now. They'll be after us."

They ran most of the night, although it wasn't always running. Nelson picked a lot of terrain that was too uneven or too thickly covered with growth for running. They kept to rocks and creekbeds as much as they could, and they stopped only a few hours before dawn to get a few hours sleep they were too exhausted to postpone any longer.

When Nelson awoke the sun was a little higher than he had wanted it to be. He got to his feet and scanned the morning sky but saw nothing to indicate sky patrol robots. He felt uneasy about not having made more territory; but the way had been erratic and uneven. A thorough search pattern could find him easily; the further away he got from the depot the better chance he stood of not being discovered by a robot. He wondered, briefly, just how many would be called out, but there was no reason to wonder. Three patrolmen dead meant a lot of searching to find the killers. He and Glynnis couldn't waste much time.

He nudged the still sleeping girl with his foot to wake her. She awoke suddenly, her hand darting toward her new knife and a low but startled cry came from her.

"Quiet." He had dug two cans out of his pack and handed one to her. "We overslept. Eat in a hurry."

She opened her breakfast. "We'll be traveling most of the day?" she asked. When he nodded, "yes," she said, "I can take it."

"I know you can; but they'll have a search out for us by now and a thorough one. If we hadn't met when we had they'd have picked you up for sure after I raided that depot—if I could have pulled it off alone."

She smiled.

"You ever see an air robot?" he asked.

"No."

"I hope you never do. They'll fly out a
