Suddenly, a faint moan emanated from the cantonment. Distant lungs blowing the neck of a wine bottle.
"What's that big weird noise?" demanded Katrinko, all alert interest.
"Aw no," said Pete. "Dang."
Steam was venting from a hole in the bottom of the thirteenth dome. They'd missed the hole earlier, because the rim of that dome was overgrown with big thriving thornbushes. The bushes would have been a tip-off in themselves, if the two of them had been feeling properly suspicious.
In the immediate area, Pete and Katrinko swiftly discovered three dead men. The three men had hacked and chiseled their way through the containment dome–from the inside. They had wriggled through the long, narrow crevice they had cut, leaving much blood and skin.
The first man had died just outside the dome, apparently from sheer exhaustion. After their Olympian effort, the two survivors had emerged to confront the sheer four-story walls.
The remaining men had tried to climb the mighty wall with their handaxes, crude woven ropes, and pig-iron pitons. It was a nothing wall for a pair of City Spiders with modern handwebs and pinpression cleats. Pete and Katrinko could have camped and eaten a watermelon on that wall. But it was a very serious wall for a pair of very weary men dressed in wool, leather, and homemade shoes.
One of them had fallen from the wall, and had broken his back and leg. The last one had decided to stay to comfort his dying comrade, and it seemed he had frozen to death.
The three men had been dead for many months, maybe over a year. Ants had been at work on them, and the fine salty dust of the Taklamakan, and the freeze-drying. Three desiccated Asian mummies, black hair and crooked teeth and wrinkled dusky skin, in their funny bloodstained clothes.
Katrinko offered the cable lead, chattering through her mask. "Man, look at these shoes! Look at this shirt this guy's got–would you call this thing a shirt?"
"What I would call this is three very brave climbers," Pete said. He tossed a tethered eye into the crevice that the men had cut.
The inside of the thirteenth dome was a giant forest of monitors. Microwave antennas, mostly. The top of the dome wasn't sturdy sintered concrete like the others, it was some kind of radar-transparent plastic. Dark inside, like the other domes, and hermetically sealed–at least before the dead men had chewed and chopped their hole through the wall. No sign of any radwaste around here.
They discovered the little camp where the men had lived. Their bivouac. Three men, patiently chipping and chopping their way to freedom. Burning their last wicks and oil lamps, eating their last rations bite by bite, emptying their leather canteens and scraping for frost to drink. Surrounded all the time by a towering jungle of satellite relays and wavepipes. Pete found that scene very ugly. That was a very bad scene. That was the worst of it yet.
Pete and Katrinko retrieved their full set of intrusion gear. They then broke in through the top of the dome, where the cutting was easiest. Once through, they sealed the hole behind themselves, but only lightly, in case they should need a rapid retreat. They lowered their haul bags to the stone floor, then rappelled down on their smart ropes. Once on ground level, they closed the escape tunnel with web and rubble, to stop the howling wind, and to keep contaminants at bay.
With the hole sealed, it grew warmer in the dome. Warm, and moist. Dew was collecting on walls and floor. A very strange smell, too. A smell like smoke and old socks. Mice and spice. Soup and sewage. A cozy human reek from the depths of the earth.
"The Lieutenant Colonel sure woulda have loved this," whispered Katrinko over cable, spexing out the towering machinery with her infrareds. "You put a clip of explosive ammo through here, and it sure would put a major crimp in somebody's automated gizmos."
Pete figured their present situation for an excellent chance to get killed. Automated alarm systems were the deadliest aspect of his professional existence, somewhat tempered by the fact that smart and aggressive alarm systems frequently killed their owners. There was a basic engineering principle involved. Fancy, paranoid alarm systems went false-positive all the time: squirrels, dogs, wind, hail, earth tremors, horny boyfriends who forgot the password... . They were smart, and they had their own agenda, and it made them troublesome.
But if these machines were alarms, then they hadn't noticed a rather large hole painstakingly chopped in the side of their dome. The spars and transmitters looked bad, all patchy with long-accumulated rime and ice. A junkyard look, the definite smell of dead tech. So somebody had given up on these smart, expensive, paranoid alarms. Someone had gotten sick and tired of them, and shut them off.
At the foot of a microwave tower, they found a rat-sized manhole chipped out, covered with a laced-down lid of sheep's hide. Pete dropped a spy-eye down, scoping out a machine-drilled shaft. The tunnel was wide enough to swallow a car, and it dropped down as straight as a plumb bob for farther than his eye's wiring could reach.
Pete silently yanked a rusting pig-iron piton from the edge of the hole, and replaced it with a modern glue anchor. Then he whipped a smart-rope through and carefully tightened his harness.
Katrinko began shaking with eagerness. "Pete, I am way hot for this. Lemme lead point."
Pete clipped a crab into Katrinko's harness, and linked their spex through the fiber-optic embedded in the rope. Then he slapped the neuter's shoulder. "Get bold, kid."
Katrinko flared out the webbing on her gripgloves, and dropped in feetfirst.
The would-be escapees had made a lot of use of cabling already present in the tunnel. There were ceramic staples embedded periodically, to hold the cabling snug against the stone. The climbers had scrabbled their way up from staple to staple, using ladder-runged bamboo poles and iron hooks.
Katrinko stopped her descent and tied off. Pete sent their haulbags down. Then he dropped and slithered after her. He stopped at the lead chock, tied off, and let Katrinko take lead again, following her progress with the spex.
An eerie glow shone at the bottom of the tunnel. Pay day. Pete felt a familiar transcendental tension overcome him. It surged through him with mad intensity. Fear, curiosity, and desire: the raw, hot, thieving thrill of a major-league intrusion. A feeling like being insane, but so much better than craziness, because now he felt so awake. Pete was awash in primal spiderness, cravings too deep and slippery to speak about.
The light grew hotter in Pete's infrareds. Below them was a slotted expanse of metal, gleaming like a kitchen sink, louvers with hot slots of light. Katrinko planted a foamchock in the tunnel wall, tied off, leaned back, and dropped a spy eye through the slot.
Pete's hands were too busy to reach his spex. "What do you see?" he hissed over cable.
Katrinko craned her head back, gloved palms pressing the goggles against her face. "I can see everything, man! Gardens of Eden, and cities of gold!"
The cave had been ancient solid rock once, a continental bulk. The rock had been pierced by a Russian-made drilling rig. A dry well, in a very dry country. And then some very weary, and very sunburned, and very determined Chinese Communist weapons engineers had installed a one-hundred megaton hydrogen bomb at the bottom of their dry hole. When their beast in its nest of layered casings achieved fusion, seismographs jumped like startled fawns in distant California.
The thermonuclear explosion had left a giant gasbubble at the heart of a crazy webwork of faults and cracks. The deep and empty bubble had lurked beneath the desert in utter and terrible silence, for ninety years.
