Suddenly he shouted, a loud jubilant shout that echoed and bounced from wall to wall. He was deafened by the reverberation. He shut his eyes tight and clenched his fists. Joy filled him. He shouted again -- and let the roar of sound lap over him, his own voice reinforced by the near walls, close and hard and incredibly powerful.

The kids in school knew even before he showed up, the next morning. They greeted him as he approached, all of them grinning and nudging each other. "Is it true your folks got a new General Electronics Model S-72ft?" Earl Peters demanded.

"That's right," Mike answered. His heart swelled with a peaceful confi­dence he had never known. "Drop around," he said, as casually as he could. "I'll show it to you."

He passed on, conscious of their envious faces.

"Well, Mike," Mrs. Cummings said, as he was leaving the classroom at the end of the day. "How does it feel?"

He halted by her desk, shy and full of quiet pride. "It feels good," he admitted.

"Is your father contributing to the NATS?"

"Yes." ;

"And you've got a permit for our school shelter?"

He happily showed her the small blue seal clamped around his wrist. "He mailed a check to the city for everything. He said, 'As long as I've gone this far I might as well go the rest of the way.' "

"Now you have everything everybody else has." The elderly woman smiled across at him. "I'm glad of that. You're now a pro-P, except there's no such term. You're just -- like everyone else."

The next day the news-machines shrilled out the news. The first revela­tion of the new Soviet bore-pellets.

Bob Foster stood in the middle of the living room, the newstape in his hands, his thin face flushed with fury and despair. "Goddamn it, it's a plot!" His voice rose in baffled frenzy. "We just bought the thing and now look. Look!" He shoved the tape at his wife. "You see? I told you!"

"I've seen it," Ruth said wildly. "I suppose you think the whole world was just waiting with you in mind. They're always improving weapons, Bob. Last week it was those grain-impregnation flakes. This week it's bore-pellets. You don't expect them to stop the wheels of progress because you finally broke down and bought a shelter, do you?"

The man and woman faced each other. "What the hell are we going to do?" Bob Foster asked quietly.

Ruth paced back into the kitchen. "I heard they were going to turn out adaptors."

"Adaptors! What do you mean?"

"So people won't have to buy new shelters. There was a commercial on the vidscreen. They're going to put some kind of metal grill on the market, as soon as the government approves it. They spread it over the ground and it intercepts the bore-pellets. It screens them, makes them explode on the sur­face, so they can't burrow down to the shelter."

"How much?"

"They didn't say."

Mike Foster sat crouched on the sofa, listening. He had heard the news at school. They were taking their test on berry-identification, examining encased samples of wild berries to distinguish the harmless ones from the toxic, when the bell had announced a general assembly. The principal read them the news about the bore-pellets and then gave a routine lecture on emergency treatment of a new variant of typhus, recently developed.

His parents were still arguing. "We'll have to get one," Ruth Foster said calmly. "Otherwise it won't make any difference whether we've got a shelter or not. The bore-pellets were specifically designed to penetrate the surface and seek out warmth. As soon as the Russians have them in production --"

"I'll get one," Bob Foster said. "I'll get an anti-pellet grill and whatever else they have. I'll buy everything they put on the market. I'll never stop buying."

"It's not as bad as that." ^! '

"You know, this game has one real advantage over selling people cars and TV sets. With something like this we have to buy. It isn't a luxury, something big and flashy to impress the neighbors, something we could do without. If we don't buy this we die. They always said the way to sell something was create anxiety in people. Create a sense of insecurity -- tell them they smell bad or look funny. But this makes a joke out of deodorant and hair oil. You can't escape this. If you don't buy, they'll kill you. The perfect sales-pitch. Buy or die -- new slogan. Have a shiny new General Electronics H-bomb shelter in your back yard or be slaughtered."

"Stop talking like that!" Ruth snapped.

Bob Foster threw himself down at the kitchen table. "All right. I give up. I'll go along with it."

"You'll get one? I think they'll be on the market by Christmas."

"Oh, yes," Foster said. "They'll be out by Christmas." There was a strange look on his face. "I'll buy one of the damn things for Christmas, and so will everybody else."

The GEC grill-screen adaptors were a sensation.

Mike Foster walked slowly along the crowd-packed December street, through the late-afternoon twilight. Adaptors glittered in every store window. All shapes and sizes, for every kind of shelter. All prices, for every pocket-book. The crowds of people were gay and excited, typical Christmas crowds, shoving good-naturedly, loaded down with packages and heavy overcoats. The air was white with gusts of sweeping snow. Cars nosed cautiously along the jammed streets. Lights and neon displays, immense glowing store win­dows gleamed on all sides.

His own house was dark and silent. His parents weren't home yet. Both of them were down at the store working; business had been bad and his mother was taking the place of one of the clerks. Mike held his hand up to the code-key, and the front door let him in. The automatic furnace had kept the house warm and pleasant. He removed his coat and put away his schoolbooks.

He didn't stay in the house long. His heart pounding with excitement, he felt his way out the back door and started onto the back porch.

He forced himself to stop, turn around, and reenter the house. It was better if he didn't hurry things. He had worked out every moment of the process, from the first instant he saw the low hinge of the neck reared up hard and firm against the evening sky. He had made a fine art of it; there was no wasted motion. His procedure had been shaped, molded until it was a beauti­ful thing. The first overwhelming sense of presence as the neck of the shelter came around him. Then the blood-freezing rush of air as the descent-lift hurtled down all the way to the bottom.

And the grandeur of the shelter itself.

Every afternoon, as soon as he was home, he made his way down into it, below the surface, concealed and protected in its steel silence, as he had done since the first day. Now the chamber was full, not empty. Filled with endless cans of food, pillows, books, vidtapes, audio-tapes, prints on the walls, bright fabrics, textures and colors, even vases of flowers. The shelter was his place, where he crouched curled up, surrounded by everything he needed.

Delaying things as long as possible, he hurried back through the house and rummaged in the audio-tape file. He'd sit down in the shelter until dinner, listening to Wind in the Willows. His parents knew where to find him; he was always down there. Two hours of uninterrupted happiness, alone by himself in the shelter. And then when dinner was over he would hurry back down, to stay until time for bed. Sometimes late at night, when his parents were sound asleep, he got quietly up and made his way outside, to the shelter-neck, and down into its silent depths. To hide until morning.

He found the audio-tape and hurried through the house, out onto the back porch and into the yard. The sky was a bleak gray, shot with streamers of ugly black clouds. The lights of the town were coming on here and there. The yard was cold and hostile. He made his way uncertainly down the steps -- and froze.
