Diamond Are Forever Part 6

"Most of 'em are already sold. We kept some as a reserve, but given the way they work it's not like we're gonna try to hide 'em in the cellar. They're in the safety deposit down to the bank."

She grabbed my keys off the table. "Okay, then, Clint, let's head on down to the bank and make that withdrawal."

There was a distant rumble of thunder. I opened the door, expecting to see clouds, but the sky was clear blue. "What in-?"

Then I saw the cloud of gray-brown dust rising from the trees. "Father!" I started running towards the forest. Jodi and the rest of the family followed.

I skidded to a halt a hundred yards into the forest. "Holy Mother!"

The prior damage to the road had been nothing. A yawning pit over a hundred feet wide dropped straight into the earth, edges surrounded somehow by upthrust rock that formed a barrier that even my truck would never pa.s.s. It would take weeks to make a new way around.

Grandpa came puffing up behind everyone else, his b.u.m leg having slowed him up. "Kids! Kids! Get back to the house now!" He caught sight of the hole in the mountainside and cursed. "Listen!"

We listened. The forest was as silent as a grave.

Then we heard faint, deliberate movement. Heading towards us.

Slades aren't cowards, but we're not stupid either. The Nomes couldn't drop the homestead, sitting on that ma.s.sive, unsuspected foundation of nickel-iron, but they could take the ground where we stood out from under us. And they were aboveground, in force, in the daytime.

"Something about this last raid," I said, "seems to have really p.i.s.sed them off!"

"Never done this before?" Jodi asked.

"Nothing on this scale," said Mamma Bea, handing Jodi a length of steel bar.

As we rounded the bend towards the gate, something burst from the underbrush, a shining stone weapon leveled at Jodi, screeching like a berserk set of rusty springs running over potholes. In bright daylight, there was little human about it-sparkling crystals on its head, faintly fluorescent violet eye-crystals, and that howling screech from the tube in its face which made me and Father jump back.

Jodi didn't even flinch. Her steel bar parried the stone sword and carried it around in a disarming arc that sent the weapon spinning away.

"What, don't get pushy with me! I've seen taxi drivers scarier than you!" Her New York accent was strong enough to cut, the only sign of how scared she really was. Jodi poked her bar in its stony chest, making it shrink back in disorientation, holding its arms up defensively. "Back off!"

It stumbled backward, b.u.mping into another one that had belatedly decided to try to back up its buddy. We took advantage of the delay to make it through the gate and lock it.

"Power on, boy!" shouted Grandpa.

"Way ahead of you, Grandpa!" Jonah shouted, outsprinting me as he streaked towards the house. We saw a dozen-two dozen-gray figures at the fence, pulling at it. Strong and well fastened as we'd made it, I could see that they'd be through it in minutes.

Then tearing-metal shrieks echoed from stone throats and the Nomes leapt away from the now-electrified fence. A few of them shook weapons in our direction, but I swore that I heard a note, not of fury, pain, or anger, but desperation in the voices.

Voices?

We all collapsed to the ground, catching our breath. Finally I turned to Jodi. "It looks like we go to Plan B."

She drew a very shaky breath. "Okay, yeah, we're now surrounded, the road's gone, and they're waving sharp stone things at us. Let's do that Plan B." She looked at me. "Just what is Plan B?"

"Talk to them," I said, grinning. "I think we just might be able to do it now."

6. Voices of the Earth

"Tell me again just how this is supposed to work, Clint?"

I should have expected Mamma to ask again. I was never sure how much of her cluelessness was an act and how much was sincere lack of understanding. I compiled the subroutine, tested it with the main one, started running it on some test data. "It's what I do, Mamma. Signal processing is, well, it's teaching a machine to do some of the same stuff that we do naturally. If you figure out how, sometimes you can eventually get the machine to do it better than we do."

She continued making sandwiches for Jodi and me. "Can you give an example your silly mother could understand, dear?"

"You're not silly, Mamma." I thought for a minute. "Okay, try this. There's a big party here, everyone making a lot of noise. Evangeline spills hot water on herself and gives a holler. Do you think you'd notice?"

"Well, sure enough I would! Don't you think I could tell when one of my own children might be in trouble?"

"I know you could, Mamma. That's what we can do with our built-in signal processing. You've got twenty voices, all making a ton of noise, but somehow our brains can sort out the different voices and notice when one specific voice is doing something unusual, like shouting in pain, even if the actual volume in the room should, by rights, be drowning that voice out."

She nodded slowly. "Never thought of it that way, but you're right. A mother can hear even a small sound by her baby over a powerful lot of noise."

"Right. So we can program a computer to do that, too, if we know how to tell it the tricks of the trade. Turns out there's a lot of different ways to do that.

"For what we're doing, the important thing is that there's different kinds of sound, what we call frequencies; high-frequency sound's high-pitched, low-frequency's low-pitched. I had a project I was on, once, that had to sort out human voices that were whispering at a distance of, oh, about three hundred yards. The kinds of signals I got from that looked a lot like some of the ones I was getting from Jodi's sensors, except that these were up in frequencies you only see bats screeching on. So I'm guessing the Nomes talk way up out of our hearing range. This converter setup will shift ultrasonic frequencies down to our range, and kick ours up to the ultrasonic."

"And I hope you've got everything set, because I don't think our neighbors are going to wait much longer." Jodi set down the heavy packs.

"Got everything?"

"Steel weapons in case they stay hostile, three sources of light-caver's lamps, flashlights, candles and matches-radio relays, walkie-talkies, food, clothing change, rope and climbing gear, hey, you name it, plus the stuff we cobbled together out of our gear. This isn't the first of these hikes I've been on, you know. Just that this mishigas changes some of the extras we need to bring. You got the code for our little universal translators, Geordie?"

"Mr. Scott, please. You know Next Gen was a weak, pale imitation. Yeah, the code should work. It's not all that complex and I could adapt a lot of the code I already had. But it ain't really a translator, remember; we're not going to understand them." I took two smooth alloy cases in rubberized jackets from her. "Oh, that's right, we already had some of these set up for long-term monitoring."

"What else could I use? We don't know how long we'll be out or where we'll be, so it's a good thing we had ruggedized, sealed cases for this kind of thing." Jodi was right-in the cave environment we expected, the gadgets we brought had darn well better be awfully tough.

"I've got the code just about set. You've got extra battery packs?"

She patted me on the shoulder. "Hey, have a little faith in your techie fiancee, neh? I pirated all the batteries from our stuff. Taking no chances."

She glanced over at the rest of the family. "I admit, all the gadgets you people have not only surprised me, they'll come in handy. Wouldn't have expected you to have short-range radio repeaters."

Grandpa laughed. "Hain't much difference twixt this adventure of yours and some of the ones we've thought 'bout doing over the years. Never had to use 'em yet, but Adam durn near did for this last trip. If most of us come with you an' provide relays with our own radios, those relays should take y'all a good long ways in before we gets out of contact."

Radio, of course, would be attenuated real fast through all that water-soaked rock, but relays could really stretch that, especially if we used the family to stretch it farther. Evangeline, Grandpa, Mamma, and Helen would be staying topside; the rest would follow us down. We knew the Nomes hadn't-and couldn't-come up through the Slade entrance, not with all the iron around and below the entrance. The only question was whether they'd try to kill us when we got out of that area.

I transferred the code into our equipment and spoke into it. There was a faint sideband of whining high-pitched noise, but the instruments showed most of the output centered around the same waveband as the signals I thought were the Nomes' voices. I put the outdoor headphones on and walked out into the night, pointing a parabolic mike in the direction of the besieging force.

"Choura mon tosetta. Megni om den kai zom tazela ku," I heard, or something very much like that. The voice was tenor, with an odd, sc.r.a.ping quality to it.

"Zom moran! Zettamakata vos bin turano," replied another, deeper voice. Chills went down my spine. It was one thing to have figured it out intellectually, another to actually hear the voices of nonhuman creatures. I pulled the headphones off and turned back. "I was right. Voices. d.a.m.n!"

Jodi nodded. "Didn't have any doubt myself, love."

Jodi and I each clipped one of the little boxes that contained the signal processors, memory, and whatnot that did the conversion to our belts, ran compact headphone wires up inside our clothing, and put on the slim-profile headphones that fit under our caving helmets. No one goes caving with a bare head, unless they want to end up with lumps or worse. We tested all the connections, made sure all the power packs and other gadgets-repeaters, lights, and so on-were well distributed, and then turned towards the door. "Let's do it. Time's getting short. They've started testing the fence again."
