I cracked and reloaded; Albert finally got every- thing pointed in the right direction and loosed a volley of lead.

We had surprised the b.a.s.t.a.r.ds, and now they weren't even sure where we were shooting from. To make things worse, the zombie troops had zeroed in on the imps, catching them in a cross fire with us.

I pushed Arlene forward, and she charged, taking advantage of the distraction. Yanking Jill to her feet, I followed; but we were several steps behind our team- mates.

Arlene broke left and Albert kept on straight, taking after the two clumps of spinys-who made the fatal mistake of turning their attention to their own pathet- ic troops.

To my horror, I realized what this resistance meant: the tunnel was breached; if the aliens knew about the tunnel, then soon troops would come pouring down the pipe, lurching directly into the heart of the last human enclave for hundreds of klicks!

Albert must have realized the terrible danger at thesame moment. He took advantage of a lull to flash a frantic sign: explosives-tunnel-blow up-hurry!

I got the message. The Mormons had intelligently lined their own escape tunnel with high explosive; if we could somehow find the detonator, we could collapse the tunnel, saving the compound.

But how? Where? I doubted even Albert knew where the nearest fuse lay-and wouldn't blowing the tunnel blow us up as well?

But considering that it was I who brought this trouble upon them, it was clearly my duty to do it...

even at the loss of my own life in the explosion.

But first we'd have to take care of these brown, leathery b.a.s.t.a.r.ds.

Arlene had gone left and Albert straight; but one imp suddenly lurched out of the darkness to our right out of nowhere. I caught it out of the corner of my eye.

"Jill!" I shouted, violating my own orders. "Look out!"

Fortunately, like Rikki Tikki Tavi, she knew better than to waste time looking. She hit the deck face first as I unloaded both barrels over her body.

The imp landed nearly on top of the girl. If it had, it probably would have crushed her to death: those d.a.m.ned demons ma.s.s 150 kilograms!

Arlene and Albert finished killing their targets, and I started to relax.

Then I noticed what the imp I had just killed held in its claws. d.a.m.n, but it sure looked suspiciously like a satchel charge.

For an instant I froze, then that little voice behind my eyeb.a.l.l.s whispered, Fly, you know, standing like a statue might not be the best career move right about now. . .

"RUN!" I bellowed, bolting straight forward, pick- ing up Jill on the fly. I ran right up to the imp and right over it, gritting my teeth against the expected blast.

It didn't blow up. Not until we had all made about ten meters down the tunnel.

The explosion was loud, but not deafening; it was the sequence of seven or eight explosions after the satchel charge that rattled my brains.

We kept running like b.l.o.o.d.y lunatics as we heard the loudest report yet. It sounded like it was directly over our heads-and the tunnel began to collapse.

A million tons of rock and dirt crashed down on my head, and something hard and remarkably bricklike cracked my skull. I was hurled to the ground by the concussion . . . and when I swam back to conscious- ness, I found myself lying half underneath a huge pile of collapsed tunnel roof. Had we been just a few footfalls slower, we'd have all been buried under it.

A steel brace arched up from our position, slightly bent. About five meters overhead I saw daylight; but ahead of us there was only rubble.

"Congratulations," gasped Arlene, picking herself up and choking in the dust. "You found the only door frame for a hundred meters in each direction! You sure you never lived in L.A., say during an earth-quake?"

No one was crippled; Jill needed first aid for a nasty cut on her forehead, and I needed about five or six Tylenols.

Albert stared forward into the collapse, then up at the sky. "Course correction, Corporal," he said. "I think it's time we rose above all this."

We made a human ladder: I stood at the bottom, then Albert on my shoulders, then Arlene on his.

Reaching up, she caught hold of the bracing beam and held herself steady for Jill to climb like a monkey up and out. She secured a rope and threw the end back down for the rest of us.

Outside, the sun was just setting, a faint flash of green in the western sky. The exploding, collapsing tunnel left a long, plowed furrow running jaggedly along the hard-packed dirt of the desert floor.

We hurried away from the site, found a rocky hill and lay on our bellies on its top. When the stars appeared, Albert sighted on Polaris, then pointed the direction we should journey. "The ranch is another four klicks yonder," he said. "We ought to be there before midnight."

Three hours later we skulked onto the deserted, burned-out ranch. Near the barn was a huge haystack.

Inside the haystack, covered in a yellow, plastic tarp, was a surprise.

Ordinarily, I'd have rather run during the night and holed up in the daylight; but the aliens were more active at night. And more important, we were all utterly spent. Arranging a three-way watch over Jill's protest, we collapsed into sleep. Despite her threat, Jill didn't awaken until Arlene shook her the next morning.

The engine of the Humvee groaned into life, the coughing gradually diminishing. The thing might actually run, I thought. Jill almost jumped up and down with excitement as the machine started to move. She was a kid again, forgetting all the c.r.a.p of the universe in the presence of a new toy. The little things that bothered her sense of dignity vanished.

She was why we would win the war against the monsters, no matter how many battles were lost. And no matter what happened to us.

"Here we go," said Albert, holding an Auto Club map as if it were a dagger. He was a lot more dashing than the President.

"Let's kick some monster b.u.t.t," said the old Arlene.

After two hours of a steady, off-road seventy kilom- eters per hour, we'd seen no signs of the changed world; but I knew this illusion couldn't last. While it did, I enjoyed every minute of it. An empty landscape is the most beautiful sight in the world when it doesn't contain smashed buildings, burning remains of civili- zation, and fields of human corpses. Of course, it would have been nice to see a bird, or hear one.

There was a long line of straight road ahead, so I asked Jill if she would like to drive the Humvee.

"Cool," she said. "What do I do?"I let her hold the wheel, and she seemed satisfied. A Humvee is a big horse, and I wasn't about to put the whole thing in her charge. But she seemed comfort- able, as if she had driven large vehicles before , . .

possibly a tractor?

Our first stop was for a bathroom break. That's when I saw the first evidence that Earth wasn't what it used to be: a human skull all by itself, half buried in the dirt. Nothing else around it-no signs of a strug- gle. But dislodging it with my shoe revealed a small patch of clotted scalp still on the bone. The ants crawling over this spot provided the final touch. What was this fresh skull doing here all by itself?

"Ick," said Jill, catching sight of my find. I could say nothing to improve on that.

"What's that odor?" asked Arlene.

"It's coming from up ahead," observed Albert.

It was the familiar, old sour lemon smell. . .

unmistakable bouquet of finer zombies everywhere.

As we resumed the journey, the terrain altered.

There were twisted shapes on the horizon made of something pink and white that glistened in the sun.

They reminded me of the flesh blocks that might still be pounding endlessly up and down on Deimos.

These were shaped more like the stalagmites I'd seen in my spelunking days. They didn't belong out here.

The whiff of sour lemon grew stronger, which meant zombies shambling nearby or rotting in a ditch somewhere close. My stomach churned in a way it hadn't since Deimos.

The sky altered as well. The blue slowly shaded into a sickly green with a few red streaks, as if pools of green sludge were leaking into the sky.

We were all quiet now, fearing that to say anything was to ruin that last glow of quiet friendship before the storm. I glanced at Jill. She wore a determined expression better than the President of the Council of Twelve wore his gun.

Arlene and Albert checked out the ammo and guns, more for something to do. Jill was content to stay up front and help drive the vehicle.

Arlene finally broke silence: "You know, Fly, they gave us more than we can pack with us when we dump the Humvee, if we're going to be able to stow aboard the d.a.m.ned train when it slows down."

"Yeah," I said. "Take what you can."

Jill looked over her shoulder. "Can I help?" she asked.

"We're doing okay," said Albert.

"You're not throwing out my machine gun, are you?" she asked suspiciously.

Albert laughed, the first sound of happiness since we crossed over into what I was already dubbing Infernal Earth. "Honey, we'll toss food and water before we let go of a good weapon."

"My name's not-" she started to say, then noticed Albert's friendly expression. Context and tone of voice made a difference. I wouldn't be surprised if we weren't the first people in her life to treat her like a person.There was the sound of an explosion to the west. "Is that thunder?" asked Jill. She stared to the right, but there was nothing to see.

"No," I said. "Someone is playing with fire- crackers."

"Something, more likely," said Arlene.

"Behold," said Albert in a low voice, obviously speaking to himself, "that great city Zarahemla have I burned with fire, and the inhabitants thereof."

Jill suddenly surprised me by turning around and facing Albert, asking: "Are you saying the monsters are a judgment of G.o.d against the human race?"

"No," he said, "I think it is a testing."

Arlene had promised not to talk religion with the boss. Now the circ.u.mstances had changed. Albert was a comrade. She'd talk about anything to a comrade.

"Would you say what the n.a.z.is did to the Jews was a testing?" she asked angrily.

"The most important lesson from what Hitler did to the Jews," he said calmly, "was that at the end of the war, they were still in the world. I'd call that a testing, one they pa.s.sed by surviving when the 'Thou- sand Year Reich' was destroyed. If they'd been de- stroyed, it would have been a judgment."

Arlene fumed at Albert, but didn't say anything.

Obviously, his answer irritated her at some level, but she couldn't think of an intelligent response.

"In s.p.a.ce," she said finally, "on Phobos, we found a giant swastika." She let her observation hang in the air, waiting for the Mormon to respond.

"What do you think it means?" he asked.

Arlene sighed. "I don't know; except it's a reason for me to hate them more."

"I would hate them just as much," said Albert, "if you had found the cross up there, or the flag of the United States, which I believe was also inspired by G.o.d. A symbol used by aliens means nothing to me.

We know them by their fruits."

"Oh, fug," said Jill. "This is like being back in cla.s.s.

Don't give me a test, Albert."

I figured it was a good time to move on. "I'm with Albert," I said. "Symbols mean nothing outside of their context. But I never expected to hear that from a religious guy!"

"I'm full of mysteries," he said.

I was glad for our little debate. It took our mind off the fact that the sky kept changing. It was now completely green. Made me think of fat frogs and mold. The lemon stench was bad enough that it seemed the same as back on Deimos and Phobos. I had forgotten how after a while you get used to anything and then you could ignore it.

Albert reminded us he was in charge of the map by pointing out we were nearing the sabotage point. "I'd say we're a mile away," he said.

"Let me take the wheel back, Jill." The kid didn't argue, glad to say. I started slowing down the Humvee.

"We need to tip it over on the tracks just past that curve," said Albert. "We don't want to derail thetrain."

"Right," I said. "They should see it in plenty of time after they come around the bend."

"Have you given any thought to how we're going to tip this monster over?" asked Arlene. "It must weigh a couple of tons."

"I sure have. That's why I brought along-Block and Tackle in a Drum!"

She didn't seem to appreciate the humor.

15.

No, really, A.S. I'm not joking."

"I'm not laughing."

I held up the drum.

Arlene squinted. "C-4? Plastic explosive?"

"Just a soupcon. A bit of spice for an otherwise drab mission."

The others stood back at a safe distance as I parked the vehicle next to the tracks, molded a goodly glob on both front and rear left tires, then rolled it forward until the C-4 was against the ground. I fused both bunches with identical lengths of det cord, lay flat and closed the connection.
