After a while he heard a car come racing up the other side of the bridge. It came to a skidding halt just beyond the tanks and several clothed figures emerged, clumsily grasping hand weapons. They moved around the tanks and advanced upon him. Gary held his position, nervously alert but striving to hide any fear of them. When they were but ten feet distant the group stopped and a leader motioned with his arm. Gary obeyed by moving away from the truck, to lean on the bridge railing and watch.

The suited troopers closed in on the truck, yanking open the rear door to examine the interior and kneeling to peer underneath. They found the body of the lieutenant — with obvious surprise, the precious cargo, Gary's hijacked supplies and nothing more. Again the anonymous leader motioned and two of the troopers climbed into the truck to roll it forward across the state line. Heavy motors broke into sudden, noisy life as one of the tanks moved sluggishly aside. The truck shot past it, and the tank resumed its former position.

The remaining troops herded Gary forward.

They marched around the tanks and at an unspoken command, Gary climbed into the waiting automobile with the others pushing in behind him. The car turned about, jockeying back and forth on the bridge to return to the Missouri shore. The nearer faces in the seat peered at him curiously. The car shot forward. Gary slumped against the back of the seat, exhausted with tension. He was in! After two years of bitter struggle and constant dreaming, he had crossed the river.

AN ORNATE brick building flashed past his window, a building which had housed the toll-collector's offices back before a part of the world had ended; now it contained a command post with a pair of sentries before the door. They stared at the passing car, watched after it when it pulled up before a smaller and newer building a short distance down the road.

At a pressure on his arm, Gary left the automobile and followed the troopers toward the small building. Someone opened the steel door, pushed him in and then crowded in after him. The door was slammed and bolted from the inside. The leader made some sort of a signal and an instant later the whole ceiling seemed to open, showering down on them a thick gray fog. Gary jerked back nervously, fighting the swirling mist with ineffective fists. The man nearest him seized his arms, held him still, and then thumped his back encouragingly. At that moment he realized what it was, where he was — this was the decontamination chamber, erected to cleanse the troops returning from patrols. Or returning from the task of throwing bodies over the bridge rails.

The fog closed around him, hiding the others.

After an interval he detected a new note in the chamber and the mist began to dissipate as blowers sucked the gas away. The other men began peeling off their suits. He lifted a slow hand to open his, and was stopped.

“Hold it, buddy. Not yet. You've gotta be processed, so keep it on until we get out of here.”
