"The cops," Erica said.

They went on calling.

"They can't raise Hellastown. They're in the shadow of the Wall!" I said. "They're on battery power, and out of line of sight to anywhere! The cops are cut off."

We'd run out of sun pretty soon, too. "Okay," I said. "Try to raise Zeke. I don't care if the cops hear us now. What can they do?"

"Right."

"Just a minute, Hon. Listen!"

The cop was still calling. There was a plaintive note in his voice. Then I heard it again: a big booming laugh.

"Shut up, Wechsung, or we'll shut you up!" the cop said.

"Sure." Sarge's voice was faint, too far from the mike to hear distinctly. "You boys are in big trouble. Maybe you better let me talk to my buddies out there before they roll rocks on top of this thing."

"Shut up, Wechsung. Four Love Victor, Mayday. Mayday!

It was pitch dark before Zeke guided us to where he and his sons had stationed themselves. He had two tractors, a big pressurized trailer with a portable powerpack, and oxygen-hydrogen fuel cells in another trailer. The police would have to rely on their internal batteries, but we had power to burn. We hooked Aunt Ellen into Zeke's system and went into his trailer.

Zeke was there with one of his sons, Ezra. John Appleby was there as well. They had a coffee pot going, and food.

"Cops have been callin' us," Zeke said. "I think they're scared. They keep tellin' us how Sarge doesn't have a helmet on. We haven't answered 'em yet."

"Think they'd let Sarge loose if we promise to leave 'em alone?" I asked.

Zeke shrugged. "Could be. Garrett, I haven't talked to 'em yet, because they don't know I'm in this. Might be a good idea not to tell 'em. Anyway, I thought I'd wait for you and Johnny here. You two got the biggest stake in this game -"

"They already want me," I said. "May as well let me do the talking. John has a pregnant wife. No point in getting you involved, John."

"Yeah, but -"

"If you have to be, you will be," Zeke said. "I was hoping you'd say something like that, Garrett. I blew out the road, and I'll go in after the bastards if that's what it takes. But I don't mind sayin' I'd as soon not see my station blown up the way Windhome was."

"What are we up against?" I asked.

John Appleby answered. "I've seen it. The tractor's no tank, but they've got a machine-gun turret mounted on top, and they've got thick plate on it. We could take it, no question about it. They've moved off into a clear space - they're going to be damned cold by morning if they stay out in the wind - so we can't drop rocks on their heads, but we could probably get close enough to throw dynamite. But I don't see any way we can get inside that thing without killing Sarge."

"Expect reinforcements?" I asked.

Zeke shrugged. "Don't think they got a message through. Hellastown isn't going to be anxious to send out a force in the dark. Never get tanks through the Gap anyway, they'd have to go around, and they won't do that at night. My other boy's watchin from up on the side of the Gap, and he'll tell us if he sees lights comin', but I think we've got till morning for sure."

"Yeah. Well, let's talk to them. Worse comes to worse, we'll offer a trade." I drank the coffee Zeke had given me, then went over and sat down in front of the radio. The trailer was big and cozy. Zeke used it as a mobile prospecting camp.

"One Dog Niner, are you listening? Over."

"Yeah, we're listening. You bastards better let us go! There'll be two battalions of marines with tanks out here by morning!"

"This won't last until morning," I said. "You've got troubles, fellows. Now let me hear Sarge talking."

"Why?"

"Because any time I ask to hear him and I don't. I'm going to assume he's dead, and there won't be any reason why we shouldn't be throwing dynamite. Clear? We've got more power than you have. You can't run away from us, so don't waste batteries. Just put Sarge on."

There was a pause. Then, "Hey kid. You're doin' okay."

"You all right, Sarge?"

"Sure. Look, don't let 'em talk you into nothing, they're -"

"That's enough," the policeman said. "He's all right."

"Good. You keep him that way. I'll be back in a bit. Out." I switched off the transmitter.

"The trouble is," I said, "they think they can wait for sunlight and just take off. With that machine gun they know they can put any tractor we've got out of action. And there probably will be reinforcements before noon. We need a way to convince them we can disable them without hurting Sarge -"

We thought for a moment. Then I had an idea. "John, you said you can hit them with dynamite. Can you hit them with paint?"

"Paint?"

"Yeah. In a plastic bag. If we splatter paint on their windscreen and solar cells, where are they going i n the morning?"

"Be damned," Zeke said. "Ezra, get on the photophone and tell your mother we need some paint down here. Paint and some bags." He turned back to me. "She won't like that. Damn bags are expensive and we can't make 'em."

"It's for a good cause. Maybe we won't need many."

"I'll throw," John said. "If I can't talk, I ought to be of some use."

It took half an hour to organize, and I let the cops stew for another half hour. We were in no real hurry. By now it would be getting cold in their tractor, even with the heaters going. Then John moved into position.

"Okay, ready," he said.

We had two radios, so we could keep John on one and use the other to talk to the cops. I called them.

"Yeah?"

"Let me hear Sarge."

"Still okay, kid."

"Good," I said. "Now. What's your name, whichever of you is in charge?"

"What's that to you?"

"I don't really care, but I ought to call you something -"

"Call him Stinky," Sarge said in the background.

"Shut up, Wechsung. My name is Larkin."

"All right, Larkin, watch close now." I switched to the other radio. "Let her fly!"

There was nothing for a moment. Then John's voice came through. "Right on target! Hit the windscreen."

"Beautiful." I called Larkin again. "Get the message? How far will you get in the morning with the solar panels covered with black paint? Oh, and don't try moving the tractor. You'll waste power you're going to need before the night's over, and there's no place you can go that we can't get upwind of you."

"He's shooting hell out of the rocks," John reported. "I wonder what he thinks he can hit?"

"Can you whap him again?"

"Sure. Here goes."

I called again. "Well, Larkin? How much air have you got? Think your relief can get through the Gap before you run out? Ready to give up, or should we paint the whole tractor for you?"

"Damn you! It's Pittson, isn't it? You're in trouble, Pittson. Let us go and we can straighten it out. Nobody's been hurt yet -"

I laughed at him.

He was off for five minutes. We waited. Then he came on. "Okay. You win. We'll turn Wechsung loose in the morning, if you hold off the paint until then -"

"Crap. You're no Marsman. Our word's good. Yours isn't," I said.

"Attaboy!" Sarge shouted in the background.

"Shut up, Wechsung. Pittson, if we let him go, will you leave us alone? Nobody around in the morning?"

"What about it, Sarge?" I asked.

"Take 'em up on it."

"Roger."

Appleby brought Sarge into the trailer a few minutes later. We got his helmet off. "You okay?" I asked.

"Few bruises. Nothing to worry about. Damn good to have friends. Thanks."

"Sure."

"Sandwiches and coffee here," Zeke said.

"Thanks." Sarge wolfed a sandwich and washed it down with black coffee. "But we got more troubles. Erica, did you kids get through to Sam? I think they went after him -"

"Yes," she said. She told him what we'd done. "Dad said he'd fight. I'm worried -"

"He'll be all right for now," Sarge said. "By now he'll have plenty of friends there. Okay, Sam's taken care of. Zeke, can you get through to Chris Martin's place?" Martin's station was on the other side of the Gap, toward Hellastown from us.
