The two weeks' training around Miami Base eventually cost us eleven lives. Twelve, if you count Dahlquist. I guess having to spend the rest of your life on Charon, with a hand and both legs missing, is close enough to dying.
Little Foster was crushed in a landslide and Freeland had a suit malfunction that froze him solid before we could carry him inside. Most of the other deaders were people I didn't know all that well. But they all hurt. And they seemed to make us more scared rather than more cautious.
Now darkside. A flier brought us over in groups of twenty, and set us down beside a pile of building materials, thoughtfully immersed in a pool of helium II.
We used grapples to haul the stuff out of the pool. It's not safe to go wading, since the stuff crawls all over you and it's hard to tell what's underneath; you could walk out onto a slab of hydrogen and be out of luck.
I'd suggested that we try to boil away the pool with our lasers, but ten minutes of concentrated fire didn't drop the helium level appreciably. It didn't boil, either; helium II is a "superfluid," so what evaporation there was had to take place evenly, all over the surface. No hot spots, so no bubbling.
We weren't supposed to use lights, to "avoid detection." There was plenty of starlight, with your image converter cranked up to log three or four, but each stage of amplification meant some loss of detail. By log four, the landscape looked like a crude monochrome painting, and you couldn't read the names on people's helmets unless they were right in front of you.
The landscape wasn't all that interesting, anyhow. There were half a dozen medium-sized meteor craters-all with exactly the same level of helium II in them-and the suggestion of some puny mountains just over the horizon. The uneven ground was the consistency of frozen spiderwebs; every time you put your foot down, you'd sink half an inch with a squeaking crunch. It could get on your nerves.
It took most of a day to pull all the stuff out of the pool. We took shifts napping, which you could do either standing up, sitting, or lying on your stomach. I didn't do well in any of those positions, so I was anxious to get the bunker built and pressurized.
We could build the thing underground-it'd just fill up with helium II-so the first thing to do was to build an insulating platform, a permaplast-vacuum sandwich three layers tall.
I was an acting corporal, with a crew of ten people. We were carrying the permaplast layers to the building site-two people can carry one easily-when one of "my" men slipped and fell on his back.
"Damn it, Singer, watch your step." We'd had a couple of deaders that way.
"Sorry, Corporal. I'm bushed, just got my feet tangled up."
"Yeah, just watch it." He got back up all right, and with his partner placed the sheet and went back to get another.
I kept my eye on him. In a few minutes he was practically staggering, not easy to do with that suit of cybernetic armor.
"Singer! After you set that plank, I want to see you."
"O.K." He labored through the task and mooched over.
"Let me check your readout." I opened the door on his chest to expose the medical monitor. His temperature was two degrees high; blood pressure and heart rate both elevated. Not up to the red line, though.
"You sick or something?"
"Hell, Mandella, I feel O.K., just tired. Since I fell I've been a little dizzy." I CHINNED THE medic's combination. "Doc, this is Mandella. You wanna come over here for a minute?"
"Sure, where are you?" I waved and he walked over from poolside.
"What's the problem?" I showed him Singer's readout.
He knew what all the other little dials and things meant, so it took him a while. "As far as I can tell, Mandella…he's just hot."
"Hell, I coulda told you that," said Singer.
"Maybe you better have the armorer take a look at his suit." We had two people who'd taken a crash course in suit maintenance; they were our "armorers."
I chinned Sanchez and asked him to come over with his tool kit.
"Be a couple of minutes, Corporal. Carryin' a plank."
"Well, put it down and get on over here." I was getting an uneasy feeling. Waiting for him, the medic and I looked over Singer's suit.
"Uh-oh," Doc Jones said. "Look at this." I went around to the back and looked where he was pointing. Two of the fins on the heat exchanger were bent out of shape.
"What is wrong?" Singer asked.
"You fell on your heat exchanger, right?"
"Sure, Corporal-that's it, it must not be working right."
"I don't think it's working at all," said Doc.
Sanchez came over with his diagnostic kit and we told him what had happened. He looked at the heat exchanger, then plugged a couple of jacks into it and got a digital readout from a little monitor in his kit. I didn't know what it was measuring, but it came out zero to eight decimal places.
Heard a soft click, Sanchez chinning my private frequency. "Corporal, this guy's a deader."
"What? Can't you fix the damn thing?"
"Maybe…maybe I could, if I could take it apart. But there's no way…"
"Hey! Sanchez?" Singer was talking on the general freak. "Find out what's wrong?" He was panting.
Click. "Keep your pants on, man, we're working on it." Click. "He won't last long enough for us to get the bunker pressurized. And I can't work on that heat exchanger from outside of the suit."
"You've got a spare suit, haven't you?"
"Two of 'em, the fit-anybody kind. But there's no place…say…"
"Right. Go get one of the suits warmed up." I chinned the general freak. "Listen, Singer, we've gotta get you out of that thing. Sanchez has a spare unit, but to make the switch, we're gonna have to build a house around you. Understand?"
"Huh-uh."
"Look, we'll just make a box with you inside, and hook it up to the life-support unit. That way you can breathe while you make the switch."
"Soun's pretty compis…complicated t'me."
"Look, just come along…"
"I'll be all right, man, jus' lemme res'…"
I grabbed his arm and led him to the building site. He was really weaving. Doc took his other arm, and between us we kept him from falling over.
"Corporal Ho, this is Corporal Mandella." Ho was in charge of the life-support unit.
"Go away, Mandella, I'm busy."
"You're going to be busier." I outlined the problem to her. While her group hurried to adapt the LSU-for this purpose, it need only be an air hose and heater-I got my crew to bring around six slabs of permaplast, so we could build a big box around Singer and the extra suit. It would look like a huge coffin, a meter square and six meters long.
We set the suit down on the slab that would be the floor of the coffin. "O.K., Singer, let's go."
No answer.
"Singer!" He was just standing there. Doc Jones checked his readout.
"He's out, man, unconscious." My mind raced. There might just be room for another person in the box. "Give me a hand here." I took Singer's shoulders and Doc took his feet, and we carefully laid him out at the feet of the empty suit.
Then I laid down myself, above the suit. "O.K., close 'er up."
"Look, Mandella, if anybody goes in there, it oughta be me."
"No, Doc. My job. My man." That sounded all wrong. William Mandella, boy hero.
They stood a slab up on edge-it had two openings for the LSU input and exhaust-and proceeded to weld it to the bottom plank with a narrow laser beam. On Earth, we'd just use glue, but here the only fluid was helium, which has lots of interesting properties, but is definitely not sticky.
After about ten minutes we were completely walled up. I could feel the LSU humming. I switched on my suit light-the first time since we landed on darkside-and the glare made purple blotches dance in front of my eyes.
"Mandella, this is Ho. Stay in your suit at least two or three minutes. We're putting hot air in, but it's coming back just this side of liquid." I lay and watched the purple fade.
"O.K., it's still cold, but you can make it." I popped my suit. It wouldn't open all the way, but I didn't have too much trouble getting out. The suit was still cold enough to take some skin off my fingers and butt as I wiggled out.
I had to crawl feet-first down the coffin to get to Singer. It got darker fast, moving away from my light. When I popped his suit a rush of hot stink hit me in the face. In the dim light his skin was dark red and splotchy. His breathing was very shallow and I could see his heart palpitating. First Iunhooked the relief tubes-an unpleasant business-then the bio sensors, and then I had the problem of getting his arms out of their sleeves.
It's pretty easy to do for yourself. You twist this way and turn that way and the arm pops out. Doing it from the outside is a different matter: I had to twist his arm and then reach under and move the suit's arm to match-and it takes muscle to move a suit around from the outside.
Once I had one arm out it was pretty easy: I just crawled forward, putting my feet on the suit's shoulders, and pulled on his free arm. He slid out of the suit like an oyster slipping out of its shell.
I popped the spare suit and, after a lot of pulling and pushing, managed to get his legs in. Hooked up the bio sensors and the front relief tube. He'd have to do the other one himself, it's too complicated. For the nth time I was glad not to have been born female; they have to have two of those damned plumber's friends, instead of just one and a simple hose.
I left his arms out of the sleeves. The suit would be useless for any kind of work, anyhow; waldos have to be tailored to the individual.
His eyelids fluttered. "Man…della. Where…the hell…"
I explained, slowly, and he seemed to get most of it. "Now I'm gonna close you up and go get into my suit. I'll have the crew cut the end off this thing and I'll haul you out. Got it?"
He nodded. Strange to see that-when you nod or shrug in a suit, it doesn't communicate anything.
I crawled into my suit, hooked up the attachments and chinned the general freak. "Doc, I think he's gonna be O.K. Get us out of here now."
"Will do." Ho's voice. The LSU hum was replaced by a chatter, then a throb; evacuating the box to prevent an explosion.
One corner of the seam grew red, then white, and a bright crimson beam lanced through, not a foot away from my head. I scrunched back as far as I could. The beam slid up the seam and around three corners, back to where it started. The end of the box fell away slowly, trailing filaments of melted 'plast.
"Wait for the stuff to harden, Mandella."
"Sanchez, I'm not that stupid."
"Here you go." Somebody tossed a line to me. That would be smarter than dragging him out by myself. I threaded a long bight under his arms and tied it behind his neck. Then I scrambled out to help them pull, which was silly-they had a dozen people already lined up to haul.
Singer got out all right and was actually sitting up while Doc Jones checked his readout. People were asking me about it and congratulating me when suddenly Ho said "Look!" and pointed toward the horizon.
It was a black ship, coming in fast. I just had time to think it wasn't fair, they weren't supposed to attack until the last few days, and then the ship was right on top of us.
