"What do you think a grenade would do to the mirror?"

"Good God, you can't be seriousl" the man said.

"I can be. You go find us some outside gear for these two." He indicated Hardesty and me. "Garrett, you go with him. I'll keep the lady here with us. And if you're not back in five minutes, mister, that eye is going out."

"I would rather you threatened me," Lady Elizabeth said.

"Yeah, I thought so," Sarge told her. "Well?"

"Do as he says, Dereck," Lady Elizabeth said. "I believe he means it."

"There's a locker room just here," Dereck told me. He led me down the corridor and through a door. "I say, what is this all about?"

"I'm not sure myself," I told him. "You're in no danger. We just want to get the hell out of here."

"You're welcome to go. You've cost us a prime night of observation, you know. We're looking for a new planet. Lady Elizabeth knows where it must be, and tonight will be perfect for finding it."

He opened the door to the locker room. There was a lot of gear hanging on the wall. I grabbed stuff I thought would fit me, then more for Hardesty. "Let's go," I said.

It took more time to get the cold-weather gear on. We were just getting dressed when we heard alarm bells.

"Into the lock. Quick!" Sarge barked.

"What about them?" I pointed to our scientist prisoners.

"Leave 'em. You two want your eye to keep lookin', you better pray we're out before the guards get here. Move!"

We carried Farr into the air lock. While it was cycling, Sarge reached into the sack and set the regulator to four pounds. That should be enough pure oxygen, if the bottle didn't freeze. It had no heater system like the ones in our suits. We had it inside Farr's jacket to help keep it warm. He was breathing, but we didn't think he could manage for himself.

The outer door opened and we bolted for the ladder. Technicians looked up from their consoles. We couldn't see expressions through their faceplates, but they must have wondered what the hell we were doing.

Sarge swarmed up the ladder, then threw down a line. I knotted a cradle around Farr and Sarge hoisted. I waved Hardesty up next. He pushed from below while Sarge pulled. Then I started up after them.

When we reached the balcony, I thought we were safe. Sarge and Hardesty carried Mr. Farr around to the big gap the telescope looked through, and went on to the outside balcony.

Then the air-lock door opened and marines swarmed through. They had p-suits and coveralls, but no coldweather gear; they wouldn't be out here long. Without all my extra gear I was feeling the cold myself, despite the exertion of climbing.

They raised their rifles and orange flashes spurted silently. I drew my pistol and fired back, also in silence. No hits for either side. Then I was through to the outside balcony. By then Sarge had lowered Mr. Farr over the side, and he and Hardesty were busy paying out line. I stopped at the slit where I could cover the ladder.

Unlike me, the marines had very little target to shoot at. I saved my ammunition until one of them reached the ladder then took very careful aim and shot him off it. Two of his buddies ran over and picked him up. They were brave men. I held my fire; they were no threat to us, and the more tied down taking care of the wounded, the better for me.

"Okay, kid!" Sarge called. The voice was loud in my helmet radio.

"Right." I waited a little longer, on the theory that the marines might have been listening. They had been. Three of them rushed the ladder. I shot the leading one and he fell, carrying the two below back to the floor. Something tugged at my right sleeve, and I looked down. There was a big rip in the coveralls and insulation, but the slug had missed me by a good two inches; that foam was thick.

I fired once more, not caring if I hit anything, and ran around the balcony. They'd be coming up the ladder any moment. It was eighty feet to the ground below. Sarge and Hardesty were running across the badlands, carrying Farr, their helmet lights dancing across the ground.

No time to go down the rope, I told myself. Eighty feet. Mars gravity is about 40 percent Earth. But it's not the same, there's a squared factor in there. No time to work it out, and the marines couldn't be far behind me.

I swung over the edge and dropped toward the ground below.

I worked it out later: I fell for almost three seconds, which seems like forever, and I hit with the same force as if I'd jumped off an eighteen-foot ladder back on Earth.

It hurt like hell. I hit and went on down, all the way, rolling, letting the thick foam padding absorb most of the force, but I still felt as if my ankles had been rammed up to my knees.

I could get up, though. It hurt, but I could run. I ran like hell toward the tractor.

We threw Mr. Farr into the bunk and Sarge climbed in with him. I put Hardesty between Chris Martin and myself in the front seat. Chris had the tractor bouncing across the rocks before we got pressure up in the cab.

"Nearest tractor air-lock is a good five kilometers from here," Sarge said.

"The marines didn't have cold-weather gear," I told him. "They've probably gone in by now." I could still feel the cold, despite everything I'd worn. "How is Mr. Farr?"

"He's alive," Sarge growled. "Chris, get us out into the Basin. They'll never find us out there. Then head cross country for Ice Hill."

"Right. How'd it go?"

"Piece of cake." Sarge said.

They had five prisoners and one repairable tractor at Ice Hill. The other Federation tractor had been dynamited.

"Nothing to it," Sam Hendrix told us. "Their first warning that we would resist came when the leading tractor ran over ten sticks of 60 percent nitro. We had very little trouble with the second."

We got Mr. Farr inside. Erica was waiting for me. "Are you all right?"

"Piece of cake. " It felt good to be able to kiss her. "And you?"

"Johnny and Ezra stopped at Windhome on the way. We picked up the two marines they left behind. Just as well for them, there was no one to get them and they would have run out of air." She took my hand. "There's a meeting in a few minutes. We're supposed to go. But we have a little time first.. "

Commander Farr was propped up on a portable cot. Ruth Hendrix didn't want him to talk, but he insisted on having us all meet in the main hall. His voice was weak and his words tended to come out slurred, but he was all business.

"It's started," he said. "There's no turning back for any of us. Sam, did you get the word out?"

"Yes. The Rim is boiling mad. Ellsworth sent out three tanks today, but they did not go past Iron Gap. Instead they escorted the police van back, and Ellsworth has been sending messages to Marsport demanding help."

"Will he get it?"

Sam shook his head. "I do not think so. Not immediately. Some of our people in the north have begun sabotage raids. The monorail south has been cut in four places. Katrinkadorp is in revolt. They will need their marines up there for a while, I think."

"Then there's been a general revolt?" Farr demanded.

"No. Except in Katrinkadorp there is no uprising. Just our people, and sabotage."

Farr nodded to himself. "Independence. They want a meeting of the leaders. Committees and debates. Is this the proper time?" He sighed deeply. "Well, we've got no choice. We've got to do something to stir up the others."

There was a long silence. Erica took my hand. We stood, waiting for someone to say something, but no one did.

"It's too early," Farr muttered. "Everything only half planned. So we make do with what we have. The Rim is ours?"

"Yes," Sam said. "Solidly, I think. Ellsworth has done our work for us, here. We had doubters, even after the destruction of Windhome, but Mr. Ellsworth has told the Hellas Region Council that he intends to close all the stations and eliminate this rebellion once and for all. One of our people had a bug in the Council Chamber, and we have been broadcasting his speech all day. Yes, we certainly hold the Rim."
