It's war. Total war. And not just war for me. For my family. For just my house.

It's for your house, too. Your house and my house and all the houses. Here and in the next block, in the next town, the next state and country and continent. The whole world, like this. Shambles and ruins. Fog and dank weeds growing in the rusting slag. War for all of us. For everybody crowding down into the basement, white-faced, frightened, somehow sensing something terrible.

And when it really came, when the five years were up, there'd be no escape. No going back, tipping back into the past, away from it. When it came for them all, it would have them for eternity; there would be no one climbing back out, as he had.

Mary was watching him. The policeman, the neighbors, the white-clad interns—all of them were watching him. Waiting for him to explain. To tell them what it was.

"Was it the hot water heater?" Mrs. Hendricks asked timidly. "That was it, wasn't it, Tim? Things like that do happen. You can't be sure... ."

"Maybe it was home brew," a neighbor suggested, in a feeble attempt at humor. "Was that it?"

He couldn't tell them. They wouldn't understand, because they didn't want to understand. They didn't want to know. They needed reassurance. He could see it in their eyes. Pitiful, pathetic fear. They sensed something terrible—and they were afraid. They were searching his face, seeking his help. Words of comfort. Words to banish their fear.

"Yeah," Tim said heavily. "It was the hot water heater."

"I thought so!" Foley breathed. A sigh of relief swept through them all. Murmurs, shaky laughs. Nods, grins.

"I should have got it fixed," Tim went on. "I should have had it looked at a long time ago. Before it got in such bad shape." Tim looked around at the circle of anxious people, hanging on his words. "I should have had it looked at. Before it was too late."

SHELL QAME

A SOUND awoke O'Keefe instantly. He threw back his covers, slid from the cot, grabbed his B-pistol from the wall and, with his foot, smashed the alarm box. High frequency waves tripped emergency bells throughout the camp. As O'Keefe burst from his house, lights already flickered on every side.

"Where?" Fisher demanded shrilly. He appeared beside O'Keefe, still in his pajamas, grubby-faced with sleep.

"Over to the right." O'Keefe leaped aside for a massive cannon being rolled from its underground storage-chambers. Soldiers were appearing among the night-clad figures. To the right lay the black bog of mists and obese foliage, ferns and pulpy onions, sunk in the half-liquid ooze that made up the surface of Betelgeuse II. Nocturnal phosphorescence danced and flitted over the bog, ghostly yellow lights snapped in the thick darkness.

"I figure," Horstokowski said, "they came in close to the road, but not actually on it. There's a shoulder fifty feet on each side, where the bog has piled up. That's why our radar's silent."

An immense mechanical fusing "bug" was eating its way into the mud and shifting water of the bog, leaving behind a trail of hard, smoked surface. The vegetation and the rotting roots and dead leaves were sucked up and efficiently cleared away.

"What did you see?" Portbane asked O'Keefe.

"I didn't see anything. I was sound asleep. But I heard them."

"Doing what?'

"They were getting ready to pump nerve gas into my house. I heard them unreeling the hose from portable drums and uncapping the pressure tanks. But, by God, I was out of the house before they could get the joints leak-tight!"

Daniels hurried up. "You say it's a gas attack?" He fumbled for the gas mask at his belt. "Don't stand there—get your masks on!"

"They didn't get their equipment going," Silberman said. "O'Keefe gave the alarm in time. They retreated back to the bog."

"You're sure?" Daniels demanded.

"You don't smell anything, do you?"

"No," Daniels admitted. "But the odorless type is the most deadly. And you don't know you've been gassed till it's too late." He put on his gas mask, just to be sure.

A few women appeared by the rows of houses—slim, large-eyed shapes in the flickering glare of the emergency searchlights. Some children crept cautiously after them.

Silberman and Horstokowski moved over in the shadows by the heavy cannon.

"Interesting," Horstokowski said. "Third gas attack this month. Plus two tries to wire bomb terminals within the camp site. They're stepping it up."

"You have it all figured out, don't you?"

"I don't have to wait for the composite to see we're getting it heavier all the time." Horstokowski peered warily around, then pulled Silberman close. "Maybe there's a reason why the radar screen didn't react. It's supposed to get everything, even knocker-bats."

"But if they came in along the shoulder, like you said—"

"I just said that as a plant. There's somebody waving them in, setting up interference for the radar."

"You mean one of us?"

Horstokowski was intently watching Fisher through the moist night gloom. Fisher had moved carefully to the edge of the road, where the hard surface ended and the slimy, scorched bog began. He was squatting down and rooting in the ooze.

"What's he doing?" Horstokowski demanded.

"Picking up something," Silberman said indifferently. "Why not? He's supposed to be looking around, isn't he?"

"Watch," Horstokowski warned. "When he comes back, he's going to pretend nothing happened."

Presently, Fisher returned, walking rapidly and rubbing the muck from his hands.

Horstokowski intercepted him. "What'd you find?"

"Me?" Fisher blinked. "I didn't find anything."

"Don't kid me! You were down on your hands and knees, grubbing in the bog."

"I—thought I saw something metal, that's all."

A vast inner excitement radiated through Horstokowski. He had been right.

"Come on!" he shouted. "What'd you find?"

"I thought it was a gas pipe," Fisher muttered. "But it was only a root. A big, wet root."

There was a tense silence.

"Search him," Portbane ordered.

Two soldiers grabbed Fisher. Silberman and Daniels quickly searched him.

They spilled out his belt pistol, knife, emergency whistle, automatic relay checker, Geiger counter, pulse tab, medical kit and identification papers. There was nothing else.

The soldiers let him go, disappointed, and Fisher sullenly collected his things.

"No, he didn't find anything," Portbane stated. "Sorry, Fisher. We have to be careful. We have to watch all the time, as long as they're out there, plotting and conspiring against us."

Silberman and Horstokowski exchanged glances, then moved quietly away.

"I think I get it," Silberman said softly.

"Sure," Horstokowski answered. "He hid something. We'll dig up that section of bog he was poking around in. I think maybe well find something interesting." He. hunched his shoulders combatively. "I knew somebody was working for them, here in the camp. A spy for Terra."

Silberman started. "Terra? Is that who's attacking us?"

"Of course that's who."

There was a puzzled look on Silberman's face.

"Seemed to me we're fighting somebody else."

Horstokowski was outraged.

"For instance?"

Silberman shook his head. "I don't know. I didn't think about who so much as what to do about it. I guess I just took it for granted they were aliens."

"And what do you think those Terran monkey men are?" Horstokowski challenged.

The weekly Pattern Conference brought together the nine leaders of the camp in their reinforced underground conference chamber. Armed guards protected the entrance, which was sealed tight as soon as the last leader had been examined, checked over and finally passed.

Domgraf-Schwach, the conference chairman, sat attentively in his deep chair, one hand on the Pattern composite, the other on the switch that could instantly catapult him from the room and into a special compartment, safe from attack. Portbane was making his routine inspection of the chamber, examining each chair and desk for scanning eyes. Daniels sat with eyes fixed on his Geiger counter. Silberman was completely encased in an elaborate steel and plastic suit, configured with wiring, from which continual whirrings came.
