But the door did not open. The key he held in his hand was the wrong key.

He was defeated. The door and the key did not match. Either he had been wrong, or the key was to be used someplace else. But where? Jennings looked frantically around. Where? Where could he go?

To one side a door was half open, a regular bolt-lock door. He crossed the corridor, pushing it open. He was in a storeroom of some sort. He slammed the door, throwing the bolt. He could hear them outside, confused, calling for guards. Soon armed guards would be along. Jennings held the Boris gun tightly, gazing around. Was he trapped? Was there a second way out?

He ran through the room, pushing among bales and boxes, towering stacks of silent cartons, end on end. At the rear was an emergency hatch. He opened it immediately. An impulse came to throw the code key away. What good had it been? But surely he had known what he was doing. He had already seen all this. Like God, it had already happened for him. Predetermined. He could not err. Or could he?

A chill went through him. Maybe the future was variable. Maybe this had been the right key, once. But not any more!

There were sounds behind him. They were melting the storeroom door. Jennings scrambled through the emergency hatch, into a low concrete passage, damp and ill lit. He ran quickly along it, turning corners. It was like a sewer. Other passages ran into it, from all sides.

He stopped. Which way? Where could he hide? The mouth of a major vent pipe gaped above his head. He caught hold and pulled himself up. Grimly, he eased his body onto it. They’d ignore a pipe, go on past. He crawled cautiously down the pipe. Warm air blew into his face. Why such a big vent? It implied an unusual chamber at the other end. He came to a metal grill and stopped.

And gasped.

He was looking into the great room, the room he had glimpsed beyond the steel door. Only now he was at the other end. There was the time scoop. And far down, beyond the scoop, was Rethrick, conferring at an active vidscreen. An alarm was sounding, whining shrilly, echoing everywhere. Technicians were running in all directions. Guards in uniform poured in and out of doors.

The scoop. Jennings examined the grill. It was slotted in place. He moved it laterally and it fell into his hands. No one was watching. He slid cautiously out, into the room, the Boris gun ready. He was fairly hidden behind the scoop, and the technicians and guards were all the way down at the other end of the room, where he had first seen them.

And there it was, all around him, the schematics, the mirror, papers, data, blueprints. He flicked his camera on. Against his chest the camera vibrated, film moving through it. He snatched up a handful of schematics. Perhaps he had used these very diagrams, a few weeks before!

He stuffed his pockets with papers. The film came to an end. But he was finished. He squeezed back into the vent, pushing through the mouth and down the tube. The sewerlike corridor was still empty, but there was an insistent drumming sound, the noise of voices and footsteps. So many passages—They were looking for him in a maze of escape corridors.

Jennings ran swiftly. He ran on and on, without regard to direction, trying to keep along the main corridor. On all sides passages flocked off, one after another, countless passages. He was dropping down, lower and lower. Running downhill.

Suddenly he stopped, gasping. The sound behind him had died away for a moment. But there was a new sound, ahead. He went along slowly. The corridor twisted, turning to the right. He advanced slowly, the Boris gun ready.

Two guards were standing a little way ahead, lounging and talking together. Beyond them was a heavy code door. And behind him the sound of voices were coming again, growing louder. They had found the same passage he had taken. They were on the way.

Jennings stepped out, the Boris gun raised. “Put up your hands. Let go of your guns.”

The guards gawked at him. Kids, boys with cropped blond hair and shiny uniforms. They moved back, pale and scared.

“The guns. Let them fall.”

The two rifles clattered down. Jennings smiled. Boys. Probably this was their first encounter with trouble. Their leather boots shone, brightly polished.

“Open the door,” Jennings said. “I want through.”

They stared at him. Behind, the noise grew.

“Open it.” He became impatient. “Come on.” He waved the pistol. “Open it, damn it! Do you want me to—”

“We—we can’t.”

“What?”

“We can’t. It’s a code door. We don’t have the key. Honest, mister. They don’t let us have the key.” They were frightened. Jennings felt fear himself now. Behind him the drumming was louder. He was trapped, caught.

Or was he?

Suddenly he laughed. He walked quickly up to the door. “Faith,” he murmured, raising his hand. “That’s something you should never lose.”

“What—what’s that?”

“Faith in yourself. Self-confidence.”

The door slid back as he held the code key against it. Blinding sunlight streamed in, making him blink. He held the gun steady. He was outside, at the gate. Three guards gaped in amazement at the gun. He was at the gate—and beyond lay the woods.

“Get out of the way.” Jennings fired at the metal bars of the gate. The metal burst into flame, melting, a cloud of fire rising.

“Stop him!” From behind, men came pouring, guards, out of the corridor.

Jennings leaped through the smoking gate. The metal tore at him, searing him. He ran through the smoke, rolling and falling. He got to his feet and scurried on, into the trees.

He was outside. He had not let him down. The key had worked, all right. He had tried it first on the wrong door.

On and on he ran, sobbing for breath, pushing through the trees. Behind him the Plant and the voices fell away. He had the papers. And he was free.

He found Kelly and gave her the film and everything he had managed to stuff into his pockets. Then he changed back to his regular clothes. Kelly drove him to the edge of Stuartsville and left him off. Jennings watched the cruiser rise up into the air, heading toward New York. Then he went into town and boarded the Intercity rocket.

On the flight he slept, surrounded by dozing businessmen. When he awoke the rocket was settling down, landing at the huge New York spaceport.

Jennings got off, mixing with the flow of people. Now that he was back there was the danger of being picked up by the SP again. Two security officers in their green uniforms watched him impassively as he took a taxi at the field station. The taxi swept him into downtown traffic. Jennings wiped his brow. That was close. Now, to find Kelly.

He ate dinner at a small restaurant, sitting in the back away from the windows. When he emerged the sun was beginning to set. He walked slowly along the sidewalk, deep in thought.

So far so good. He had got the papers and film, and he had got away. The trinkets had worked every step along the way. Without them he would have been helpless. He felt in his pocket. Two left. The serrated half poker chip, and the parcel receipt. He took the receipt out, examining it in the fading evening light.

Suddenly he noticed something. The date on it was today’s date. He had caught up with the slip.

He put it away, going on. What did it mean? What was it for? He shrugged. He would know, in time. And the half poker chip. What the hell was it for? No way to tell. In any case, he was certain to get through. He had got him by, up to now. Surely there wasn’t much left.

He came to Kelly’s apartment house and stopped, looking up. Her light was on. She was back; her fast little cruiser had beaten the Intercity rocket. He entered the elevator and rose to her floor.
