BOB
BUCKLEY
The wind was out of the west. It
carried before it a ruddy haze of dust that whispered gently against the
deserted recreation dome. All about lay the canyon, an abyss of ragged,
multicolored stone. It seemed to cup the Noctis Lacus Mining and Exploration
Settlement with friendly, severe shelter.
Tom McCormick rested his broad
forehead against the cool plastic of the port a moment longer, enjoying the
view while he attempted to ignore the persistent twinges of conscience that
threatened to tear him away. The evening, descent of the sand spiders had
begun. The tiny wisps of life, not spiders at all but small insectoids with
limbs as attenuated as a king crab, whirled down the cheer crags like Duffs of
ebony snow, their unbelievable numbers concealing the brilliant exfoliations of
lichen that stippled the cliffs like heatless flames of orange, scarlet, and
chrome yellow. For the spiders the dunes that mounded the flats spelled
insulated safety from the rigors of the freezing Martian night.
The second man in the dome lounge
was not interested in the view. He was young, with plain, strong features, and
his large hands almost swallowed up his knees as he sat hunched on the edge of
the couch staring at the free-patterned floor of fused plastic.
"I've never asked you for
anything before, Tom, but . . ."
The little biologist turned away
from the port with a long sigh. "Then don't ask now, Paul. You know my
position, and I think you understand why I came to it. If it weren't that you
were being . . . well, we can let that drop for now. What matters is that I'm
rejecting an applicant I suspect to be unable to adjust to colony life. If
Jeanne won't fit into a crew successfully there's no way she can fit into the
colony. She might not even survive."
McCormick's light cotton tunic, an
import from the pressurized farms of Hellas City, revealed a well muscled, but
compact frame, for he was just barely over five feet tall. But it was his face
that caught and held the attention: the skin was patterned by a tangled web-
work of tiny wrinkles that puckered into tiny sunbursts about his deep-set
eyes.
"You probably think I'm being
paternalistic, Paul," he went on. "Perhaps I am. I'm remembering a
dome blow-out a long, long time ago when the Noctis settlement was a single
dome and three prospectors. One of them was a girl. Her name was Jeanne, too,
fresh out from Earth she was." McCormick glared at the other. "I
couldn't save her. But at my age a man's already made a lot of mistakes. He
avoids making them again because he just doesn't have the energy. If you were
older you'd understand."
"I understand just
fine," Culkin snapped. "What all this boils down to is
prejudice." But if the boy was expecting an angry retort he was
disappointed, for McCormick only smiled sadly. Behind him the port was glowing
with a soft, rosy-colored twilight. The flats were in deep shadow, now, and in
another few minutes the entire canyon would be dark.
"She's been pretty friendly,
hasn't she?"
Culkin flushed a deep crimson that
was not entirely due to the sunset flaming along the bluff-tops. "That's
not why I'm defending her."
"Isn't it?" McCormick's
eyes were as expressionless as polished glass.
"No! Jeanne's an excellent
geologist. And Sheldon's given her top scores in sandcar handling."
"And that's not all she
handles well." The overhead lighting of the lounge came on with a shimmer,
making it seem even more spartan. The Noctis Lacus Settlement was still little
more than an outpost. The main colonies at Claritas and Hellas were different,
both of them growing up around subsurface aquifers and rich loess soils with
the farming supplemented by ore extraction contracts leased to Lunar Industries
and Homeworld corporations. Noctis would grow, also; but in time, not
immediately. The caverns had to be mapped, the ore veins identified, before the
heavy work could begin. But there was a future in the great canyons. McCormick
knew it, and so did the slim brunette standing framed by the airseal of the
portal. It had been Norah who had convinced McCormick to bring the crew west
and hire their two cave buggies out to the Noctis division of the Bureau of
Extraterrestrial Lands, the only government on Mars. Waist-length braids swung
like glossy snakes about the girl as she moved into the lounge.
Culkin seemed to sense the arrival
of an ally. "Tom's rejected Jeanne Alexander as a replacement for Sally.
Can you believe that, Norah?"
The girl laughed as she threw
herself down on a couch. "Yep." Then she looked at McCormick
"Why?"
For an answer the biologist fished
in one of his tunic pockets and tossed a tiny object to the girl. She caught it
on the fly automatically and easily. "Know what it is?" he asked.
Norah turned the thing about in
her fingers. "Drug capsule with a red gel coating. So what?"
"I found it in my office
after Alexander had been there for an interview. She doesn't know she dropped
it."
"Must be pretty terrible from
the way you're looking at it, Tom."
"It's an engram transplant, a
memory capsule. No way of knowing precisely what it is without ingesting it.
Might be a technical journal article, or a joyride across the ice fields of
Titan."
"Oh!" Norah put the
capsule into an empty dish and wiped her fingers delicately on her pants-leg.
"I wonder how she got it past the customs inspection on Phobos?"
"It's no crime to possess
engram caps," Paul Culkin protested loudly. "Any of us could place an
order with Earth. The things are expensive, but certainly not the instruments
of destruction that Tom accuses them of being. The caps are even catching on at
Luna, and I think that's all the more reason for not rejecting Jeanne
just because she conforms to Homeworld technology and mores."
The landscape outside the port was
growing darker. The sky was almost black, holding a thin tracery of ice clouds
that were slowly drifting southward, toward the icebound pole. The highlands
atop the bluffs would have another thirty minutes of light, but for the canyon
abysses night had fallen already.
Norah shifted on the couch.
"Well,
we need a replacement for Sally, Tom. There's no getting around that. If you
delay any longer we're going to lose credits. It's no good just letting a buggy
go unused. And the Bureau won't like your rejecting an applicant without so
much as a trial run. I also agree with Paul that you can't reject her solely
because she lives up to Earth mores."
"You'd
have me sign on a New Guinea cannibal just so long as he could drive a cave
buggy," McCormick said with a sigh.
"That's
an idea." Norah grinned. "Let me propose a compromise. Give Jeanne a
chance to prove herself in the field. We can rearrange buggy crews."
"You
want me to double up with Paul?" McCormick glanced at Culkin thoughtfully.
"That would work. He's a geologist, and that maintains technical balance.
But still ..."
"I
like it," Culkin declared loudly, standing up to begin pacing the floor,
his hands clasped behind his back. "It gets you off the hook, Tom."
"It
gets nobody off any hook. Mars can still kill, especially in the caverns, and
your Jeanne doesn't understand us, nor does she understand how a crew
functions. On Earth the individual works for himself, and equality is
legislated. Put someone like that into the Bureau system and you've got all the
makings of bad trouble."
"I'm
willing to risk it," Culkin shot back angrily.
"Damned
decent of you, considering it's going to be Norah who's taking the
chances."
"Relax,
Tom." The girl was smiling. "If I don't mind a risk, don't you mind
it for me. I'm a big girl, and besides, it's a lot harder for a woman to fool a
woman."
The
golden bar of sunlight that had emblazoned itself across the east rim of the
canyon narrowed to a sliver and vanished. Black shadow swallowed up the port.
Off in the distance, where the sole roadway climbed out of the canyon on a
series of switchbacks, the headlamps of an ore truck threw banners of white
glare across the walls of rock, painting them for an instant in stark relief.
"One
patrol?" McCormick asked finally.
"It
only takes one to smoke out a loser," Norah said quietly. "Tomorrow
you can check her out on the buggies while Paul and I finish up that workdome
contract. That night we go down in the caverns, and when we get back the lady
might very well ask for a transfer on her own. The caves can do that to a
newcomer who goes deep for nothing more uplifting than a few credits."
2.
The
creature was without awareness, without identity. It could not comprehend the
endless dark, nor the slow ebb of heat energy into its jelly-like body through
the thermopods bedded deeply through adamantine rock toward the magma pockets
that underlay the deep caverns. In its structure, part protoplasmic, part
mineral, the creature was a curious combination of life and unlife. It had
existed in an unchanging state for millions of years. It had sensed when the
floods had come, it had sensed when the torrents had drained away. Its main
body lay unmoving within the ancient grotto with the evidence of its hunger all
about: empty crevices where once there had been rich veins of ore. The feeder
tentacles had etched the stone with powerful acids and left it pocked and
crumbling. Now the ores were played out. They had lasted long, but all things
come to an end. The creature was quietly, inevitably starving to death. It did
not "know" this, but its great bulk was permeated with foreboding.
The five simple ganglia, copies made from the brains of insectoids that had
blundered into its feeding tentacles at long intervals, were alert. But there
was no prey to be found, or absorbed. Dissolution was coming rapidly. Nothing
was left to it but division, the entire bulk disintegrating into a
thousand-plus mobile, diminutive reproductions, one or two of which might chance
upon another rich grotto and grow to maturity, sending thermopods down to suck
the heat of the planet. Already the process of division was beginning as
chromosomal structures within the central cell mass began aligning into a
precise and complex pattern.
3.
"Coffins
with wheels!" The girl's tone implied that she was not impressed by the
two cave buggies drawn up in the equipment dome. She put her gloved hands on
the hips of her suit and shook her head from side to side within the
transparent helmet.
McCormick
grinned. He knew the buggies weren't pretty and he didn't much care. They had
been designed for strength, and they gave off the massive presence of two
granite boulders. Neither was longer than twelve feet, nor wider than six, even
taking into account the six large wire wheels arrayed along the lengths of the
tubular hulls, three to a side. Each of the vehicles was double-ended, since
rarely did a buggyman find himself with the luxury of the room to turn around.
A pressure-tight bulkhead separated the forward control-room from the rearmost,
and the hull itself was 200mm machined Martian steel, the finest this side of
Luna, with a bright orange envelope of Teflon bonded over the metal. Two
hatches, one at the bow, the other at the stern, opened inward, and above their
rims were the inset, glassine-shielded driving lamps, three to, an end, and
above these the tiny driving ports arrayed in a curve before the padded couch
on which the driver had to lie, belly down, the entire trip. Caving was
profitable and interesting, but no one as yet had been foolish enough to
acclaim it as fun.
McCormick
reached through one of the open hatches and moved a switch on a control panel.
A section of hull rose with a hum, exposing a slim pod mounted on an extensible
pivot arm.
"This
is the sensor pod," he explained. "It contains a spectrographic
laser, a TV camera, and a searchlight. Both crewmen share it, but it is usually
operated by whoever isn't driving the buggy at the time. Now, climb
inside. You've got until 1400 to memorize the controls. I want you to be able
to work them in complete darkness, because even in a power outage the motors
run. They're fail-safe, and the wire wheels serve as sensing antennae even if
you can't see the cave walls. If you want to live to be an old caver you'll need
every trick we can teach you."
The girl dropped into a crouch and
peered through the open hatch into the interior of the buggy. "Not much
room in there, is there?" When McCormick didn't answer she frowned.
"Look, I spent most of last night going over the construction plans and
control schematics with Paul. It's all up here now." She tapped a gloved
finger against her helmet.
"Schematics in the brain
don't mean reflexes in the muscles. Inside." When the girl didn't move
McCormick sighed and gazed resolutely up at the straining plastic of the dome.
"It's that or the next ore train back to Claritas," he said firmly.
This time Jeanne moved, though not
without complaint.
4.
Paul Culkin put down the battered
melt-gun and studied the fresh seam of joined plastic critically. It seemed
secure. Satisfied, he put the tool down and sat back on his-haunches. The thin,
dry wind of Mars kicked up a flurry of orange dust and sent it whirling across
the flats. Culkin's suit was already coated, its brilliant scarlet subdued to
muted orange. As for Norah's, it was now an ugly brown, the blue color
completely obscured.
The girl glanced over.
"What's wrong?" She had been working all morning to assemble the
Central Equipment Base for the dome foundation.
Culkin looked away from the ore
train that was just starting to move out from the loading docks of the
bigstill experimentalore crusher. Behind it the Noctis Lacus settlement
showed as a cluster of twelve dark purple hemispheres, like a bunch of Concord
grapes half buried in orange dust. The sun was directly overhead, a tiny,
glaring point of light that always seemed too small, and far too bright. It
made the lead sandcar of the train glow like fire as the sunlight illuminated
the orange hull with the yellow pennant streaming back from the tip of the whip
antennae. In a day the train would be at the big colony at Claritas. There the
ore would be smelted, then shuttled up to Phobos for loading into the big
freighters . . ."lummoxes," as the ponderous, ion-powered vessels were
known among the colonists.
The geologist's cheek twitched.
"Nothing's wrong."
"Then you're daydreaming on
my air allotment. Get back to work."
"I bought the air
today," Culkin snapped irritably.
"Oh. That's different."
The girl studied the nearly completed framework, the basepad of fused plastic
that was puddled across the low rise of dolomite. "Dream all you
want."
"I wasn't daydreaming, I was
worrying."
"Might as well stop that. It
never accomplishes anything except to promote ulcers." Norah grinned.
"Is it Jeanne?"
"Yeah." Culkin began
joining brace frames again.
"You're afraid she's going to
shoot her mouth off at Tom and get sent back to Hellas, forthwith."
"That's about it,"
Culkin said flatly. "Jeanne's pretty, but I think her mouth is bigger than
her brain sometimes. And it amazes me that a girl so intelligent is so lacking
in common sense." He put the melt gun down again. "Know what she told
me last night?"
Norah waited expectantly.
"She wants to map out an ore
strike on her own, register it, and sell it to some corporation on the
homeworld. That's why she came out to Mars . . . to get rich!"
Norah laughed softly. "Quite
a feat if she can pull it off."
"I know." Culkin went
back to work. He finished the last joining and swung the entire assembly
upright, carrying it over to the Central Equipment Base. Norah helped him seat
it and bolt it down to the basepad. The steel footings for the meteor shield
were already in place and all that remained to be done was for a halftrack to
deliver the dome envelope and pump equipment. That part of the erection had
been contracted out to another crewthere were seven at the settlement, all
engaged in mapping the caverns spatially and geologically, and in the still
experimental ore extraction plant. Piecework, like the dome construction,
allowed the crews a chance to earn work bonuses, and when the month's
allowances for air, food, and other life supports were totaled up McCormick's
crew would be at least a hundred and fifty credits to the good.
Norah slid the last lock-nut into
place and fused its head with her gun. Culkin began a last recheck of their
work.
Norah holstered her melt gun and
stood up. She studied the colossal cliffs that seemed to lean over the flats,
always about to topple and crush them beneath a terrible weight. "You know
Tom was right last night, don't you?"
"I don't know any such
thing," Culkin snapped back.
"Jeanne's from Homeworld.
Anyone growing up with that population, under such fierce competition, is going
to think of herself first and the crew second."
Culkin looked across the flats to
the settlement. The huge halftracks that made up the ore train were nearly to
the base of the cliffs, and the roadway that snaked precariously up the stepped
bluffs. "I can bring her around," he said firmly. "When she sees
that her survival depends on the well-being of the crew she'll come
around."
5.
Martian caverns were curious to
see. They had not been formed by slow seepage of groundwater, but rather a
combination of seepage and scouring action. Thus there were no stalactites dangling
from the curved and deeply grooved ceiling; no stalagmites thrusting up from
the sloping, concave floor. The caverns almost seemed artificial in their
tubular appearance, as if they were colossal, pre-planned drains of a forgotten
race of burrowing aliens.
Like the layered walls of the
abyssal canyon complexes, a hundred million years of geologic history lay
exposed in the subterranean ramblings. The caves had been dug gradually over
the ages by sediment bearing torrents released periodically as the planet swung
nearer the sun. The polar caps had melted then, forming an unstable atmosphere
of water vapor and carbon dioxide that nightly condensed into blizzards of
planetary proportions, draping highland and valley alike with thin drifts of
snow. With dawn and the return of the sun, the new-formed snowfields melted
into a steamy runoff; a mere trickle at first, but a trickle that rapidly built
into flashflood proportions as the muddy liquid was gradually funneled into the
equatorial canyons. There the waters collected, seeping downward. Cracks became
caves, and the galleries lengthened and widened steadily. Through millennia the
process continued, and the caverns were never completely filled, for the water
percolated downward, and as it neared the mantle, flashed into steam. Ascending
crustal faults, it came out upon the surface again in hotsprings and geysers.
It was the caverns that allowed
life to exist at all on Mars, for without them the water vapor released at
intervals by the melting of the ice caps would have been lost to space. Because
of them, however, through a mechanism somewhat like the oceans of Earth, the
planetary waters were systematically recycled and doled out to the surface
lands in usable form, again and again.
But mankind enjoyed the caverns
for an entirely different reason. Already the two buggies were halfway through
the completion of their mapping patrol. Now they were descending a main
gallery, the run holding steady to a twenty-degree slope. McCormick's buggy was
in the lead, the biologist steering while Culkin kept up the charts. Prone on
the narrow couch in the forward compartment, the biologist watched his
reflection nod in the thick crystal of the ports. Beyond the crystal he could
see the beam of the mobile pod sweeping across the cave walls, pausing
momentarily as the geologist took readings with the laser.
"Iron ore," Culkin
reported at last. "If it's the same layer that runs back under the
settlement we're down to the 350-million-year level. I'll know for sure if we
hit oil shale at 390. Damn, I wish we had one of those mythical time-machines.
I'd give anything to be able to see Mars when it still had its lakes."
"When Tycho Base gets around
to inventing one I'll have it installed forthwith," McCormick promised.
"But you'd be disappointed. Lieberanz says the oil-forming lakes were
nothing more than stagnant mudflats with a meter or two of scummy, alkaline
water over them. He wrote a paper on it last year. Says effects of the wind
probably kicked up big bubbles of alkali froth and sent them tumbling across to
the shore where they piled up in big, sudsy ridges."
"Sounds nauseating. Look,
there's a fungus colony." The spot illuminated a knobby mass of pale
tissue wedged into a moisture-oozing crack in the ore. "Pretty small.
Looks unhealthy," Culkin decided.
"We're deep." McCormick
reminded him. "Too deep for most cave life, and that means too far away
from the sun."
Fungus colonies lived off decaying
particles of organic matter percolating down through the stone, like the
oceanic abyssal life on Earth. By the time a piece of foodstuff drifted down to
the bottom everything it passed for a distance of six kilometers or so had had
a bite of it. There was never much left, which was why such life-forms were so
small.
McCormick guided the buggy on.
Twenty meters behind came the second buggy. Jeanne Alexander was steering. Five
times, now, McCormick had had to order the girl to drop back to a safe
distance. She seemed determined to ride his tail, almost as if she were afraid he
might find something and not pass it on.
The slope steepened to thirty
degrees. The gallery narrowed.
"Just hit oil shale,"
Culkin reported with an air of triumph. "Looks like it's going to be a
sizable bed. So much for your scummy lakes."
Abruptly the gallery divided. A
shaft exited through the floor of the gallery leaving two narrow ledges barely
wide enough for the passage of a buggy on each side. McCormick took over
control of the spot and flashed it down into the pit. A ramp of silt became
apparent leading down into the darkness of a lower level. Apparently there had
been a collapse of the gallery floor in the distant past and the floods had
been diverted downward. He sent the buggy toward the left ledge and switched
the transceiver circuit into the outside antennae.
"Jeanne?"
"Here, Tom." The girl's
voice struck McCormick as being surprisingly calm.
"I want you to take your
buggy down. There's a ramp of silt, so the descent won't be difficult. Just
mind that you keep your speed low, and don't over-drive your lamps. Drop signal
boosters at twenty-meter intervals so we don't lose contact. Can do?"
"You're the crew chief."
The rear buggy accelerated, slewed about the other and whirred down the
cavernous drain. In a moment it was gone, even the brilliant glow of its lamps
swallowed up by the gloom. Tom McCormick watched uncomfortably. He was being
possessed by a terrible sense of wrongness. If this was a mistake . . . he
shook his head angrily. Why, when he had had the chance, hadn't he held firm? Why
hadn't he sent the girl back to Hellas?
6.
The creature stirred, ganglia
alert. The air pressure within the grotto had subtly changed. Something very
large was approaching. A sensory tendril reported the event and cellular
dissolution slowed and stopped. The multi-cellular gel that formed the central
mass began to re-form, spreading itself thinly across the grotto floor until it
became a vast, semi-liquid puddle of mindless hunger.
7.
The buggy careened wildly down the
broad ramp of crumbling silt, the grooved walls of the immense cavern painted a
livid, glaring yellow by the driving lamps.
"What a stroke of luck,"
Jeanne said gloatingly. "I wonder if Paul suggested to Tom that we take
this lower gallery by ourselves. If so, I love him."
"Womankind loves the
malleable," Norah replied dryly. "But slow down. This isn't supposed
to be a race to our graves." When the scene outside the rear cabin continued
to bounce wildly she tried again. "It you don't, ol' girl, I'll override
your controls and back this thing down myself."
The buggy slowed slightly in its
crazy descent. The walls ceased to be a blur and began to show strata of
mudstone and shale. There were also intrusions of pyroclastic stone, quartz
included. But there were curious cracks, or crevices winding through the stone,
as if veins of ore had been mined away. In some areas the stone showed porous
and badly eroded, as if by acid.
"Are you adventurous,
Norah?"
"What does that mean? The
question, that is." Inwardly she already knew, she had been expecting the
invitation for hours.
"I was wondering if you like
to ... well, gamble. An individual could become fantastically wealthy by making
just one strike down here. Both Luna and Earth need raw ores badly and they're
willing to pay for them handsomely."
Norah smiled. The cavern opening
was dwindling rapidly into a narrow archway of shadow. A thin cloud of
disturbed silt hung above the ramp. "What about Tom and Paul?"
"Paul I can handle. As for
Tom. I've seen those looks the two of you pass back and forth when you think
nobody's looking. You know a man's weakness. Grab him hard and make him walk
the line . . . your line. It's easy."
The buggy was speeding up again,
swaying from side to side on the uneven sediments of the ramp.
"You're asking a lot. And I'm
curious, once you make this big find, who are you going to sell to? Lunar
Industries and the Home-world corporations deal through the Bureau."
"There are other
groups," Jeanne answered mysteriously. "Some aren't quite-so open in
their dealings as the big corporations, but they wield as much clout. Also, they
don't care so much for laws."
Norah drummed her gloved fingers
thoughtfully on the rim of the port. "There are other details, you know.
Removal of the ore, processing, transportation and distribution. The Bureau
handles that for the crews. I don't see how a free-lance prospector could
manage."
"That's my contact's problem,
all I'm in this for is the credits. They say they can handle everything else,
and I believe them."
"The original rugged
individualist, huh? Unfortunately you're working with obsolete philosophies.
Mars isn't the frontier that Earth was in the Nineteenth Century. Teamwork is
what counts, now."
"That's OK by me, Norah.
Teamwork is just fine, so long as I'm the captain of the team. That's the only
safe position. It's a lot easier to step on a cat on the ground, than knock him
out of a tree. And that's where I want to be, up in that tree . . . the power
tree!"
The buggy dashed off the ramp with
a bounding leap that caused the tubular body to bounce on the wire wheels as if
they were springs. It sped across a wide fan of sediment into a huge grotto
whose floor was a smooth, white blanket of salt. The individual crystals
sparkled in the lamp glare like a graveyard of fallen stars.
"Jeanne, slow down!"
Norah shouted anxiously.
But it was already too late. The
buggy entered what seemed to be a wide poor of shiny tar. It lurched to a stop,
its stern hanging free over the salt, just as the tar began to contract,
balling up into a towering mass. Norah screamed.
8.
Paul Culkin fired off the laser
again. A pinpoint-sized spot on the cavern wall glowed white, then crumbled
into ash. "More oil shale," he reported, making a notation on the
rough chart. "Air's full of ammonia. Trace of water vapor, too. Probably
getting close to the mantle. Is Sheldon still trying to convince the circuit
agent from the Bureau to have a pilot heat exchange engine installed in one of
the deep galleries?"
McCormick cursed as his helmet
rang against the low ceiling. "Yes. The settlement's already got the
water, buried deep. All we need now to expand is a dependable power
source."
"Maybe Jeanne will want to
stay, then."
"Don't count on it. She'll
hang around until she builds up enough credits to leave, then skip off like a
wind demon. Her driving purpose in life is physical comfort. She's not a
builder, just an exploiter."
"Maybe not," Culkin
insisted stubbornly. "Last night I explained how the Bureau serves as a
planetwide clearing house for construction and settlement planning. How it finances
exploration and mining ventures."
"I know, she told me about it."
McCormick laughed for the first
time since the patrol began. "She sounded disillusioned. Told me that the
only people on Earth who swallow the official government line are in subsidized
homes eating soymush with rubber spoons. Said the joint assets accounts were
just a communistic scheme developed by the Bureau to keep the masses poor and
laboring."
The buggy began to climb over a
low mound of rubble that had fallen from the ceiling.
"Speed up, Tom!" Culkin
shouted suddenly. ,
The buggy spurted ahead as
McCormick twisted the throttle.
"Good. Now let me take over
steerage."
The biologist complied without
question. The buggy began to creep backward.
"What's the matter?"
"Something grabbed at us as
we went by ... There it is. I've got the spot on it. Looks like a blob of black
jelly. The tentacle is still contracting. Must have a slow metabolism like the
sand spiders.
"It looks like a length of
black string, but it's potent! Ate a long streak through the Teflon hull
coating, all the way down to the steel."
McCormick twisted on the couch,
straining to see the dark shape bathed by the harsh glare of the spot. It
seemed to have no definite form. Tentacles were budding out at random all over
its exterior, their tips inching caterpillar-fashion over the stone. One such
tentacle was crawling toward the buggy. It paused atop a ledge, swelled up like
a child's balloon, then darted toward the hull like a tiny, ineffective
jet-propelled projectile. The lump of flabby flesh impacted on the cave floor a
meter away from one of the coiled-wire tires.
"That thing shouldn't be
alive this deep," McCormick said thoughtfully. "I wonder if we dare
analyze it. I'd hate to sacrifice it, then discover that it was the only
specimen of its kind."
Culkin sent the spot leaping
across the stony arch of the ceiling and down the opposite wall. He laughed
suddenly. "We're in luck. There's a second one ... up on that ledge. See
it?"
"Yeah. Hit the big one with
the laser and let the computer chew on the data for a while."
The needle of coherent light
stabbed into the first blob and the creature flashed at once into greasy black
smoke. A cracking mass of glowing carbon was left behind. Culkin hummed
atonally as he waited for the read-out.
"Here it comes," he
started to say, but he was not to finish.
McCormick jumped as the emergency
call light began to pulse scarlet.
"What?" he demanded
sharply.
"Tom, Norah. We're in trouble
. . . two kilometers along the lower gallery. Something has the buggy . . .
can't see what . . . being up-ended . ." The noise of something falling
came through the pick-up. "Jeanne, get out of here. MOVE!"
The transmission broke off
abruptly, as if a sending antennae had been disabled. The last thing McCormick
heard was Norah cussing like a spacejack.
9.
The creature had no awareness, but
it had been stimulated, and that stimulation had triggered off reflex loops
from its ganglia. The unwieldy mass of protoplasm began to contract vigorously.
Fibrous cords stretched painfully. Thermo-pods snapped as they were forced to
expand beyond their tensile strength. Wisps of steam shot from the exposed
tubes. The severed length of one thermopod jumped from its tube in a long
streamer of dark jelly and splattered against the lofty ceiling of the grotto.
Its exodus was followed by a small tendril of molten rock that raced across the
salt a short distance, then froze into a gray rope of stone.
But the sacrifice of a few
thermopods was minor when weighed against the mineral wealth of the object
mired in the creature's soft mass. Ingestion began at once. Floods of smoking
acid vomited forth, bathing the buggy. The wire wheels vanished at once, as if
formed from spun sugar instead of high-grade steel. 10.
Brilliant lamps illuminated the
interior of the gallery with flickering white fire as the buggy descended the
silt ramp in a rush. It leveled out. The metal tires hummed as McCormick braked
violently. The buggy shuddered and slid sideways, coming to a stop against a
buttress of stone.
The figure continued its stumbling
advance over the salt, its suit and helmet bright in the lamp glare. McCormick
saw that the suit color was blue, not yellow, and knew joy. And guilt an
instant later. He tore an emergency-pack down from its clips and opened the
hatch, calling for Culkin to follow.
They met Norah ten meters on. The
girl held a hand torch, and one shoulder of her suit bore a long, ragged burn.
As McCormick daubed on sealer he tried to ignore the broken thermal webbing.
"Where's Jeanne?" Culkin
demanded anxiously.
Norah didn't answer at first.
Instead, she swung the torch beam around so that it pointed back the way she
had come. It showed a vast, dark shape mounded on the salt. It sparkled like
translucent jelly, and a bubble seemed to be forming on its dorsal surface,
bringing to McCormick's mind the image of gas rising through thick crude oil.
The girl made a sound like a sob.
"There," She said. "In there with the buggy."
11.
The creature accepted the feast of
nutrients with mindless satisfaction. Then, as its immediate metabolic hungers
were quenched, its feeding became more selective, for certain sensors were
reporting the presence of a uniquely complex protoplasmic structure, no simple
insectoid this time, but a rich template of new structures, and new behaviors.
The acids did their work swiftly, stripping
away cell walls, dissembling alien protoplasm into basic genetic components and
protein molecules. The chemical investigation was painstaking in its
thoroughness. Nothing was destroyed, instead it was copied. The creature began
to modify its own structure, drawing massive amounts of energy from the rock
through its thermopods. A new form began to grow, cell by cell, organ by organ.
Abruptly awareness burst upon it like a dawning sun. And with the awareness
came the memories, alien thoughts. The creature had conquered, and yet in
conquering, it had lost itself to its prey. For the first time the creature
"looked" upon its grotto and knew where and what it was.
12.
Norah screamed and took a panicky
step backwards. She bumped into McCormick and he seized her automatically in
his arms without thinking. What loomed above them banished thought.
"God!" Norah hissed.
"What is that horror?"
McCormick did not answer. The
hideous excrescence budding from the central mass of the blob glistened with an
evil sheen in the torch-light. Iridescent colors swam crazily as the figure
pulsed from within. This added to its dread aspect, for from the waist up it was
a perfect reproduction of Jeanne Alexander, like a nude statue carved from
flawless, jet-black obsidian. The hips and legs were still forming, their
detail crude, but sharpening with each passing moment. The upper parts of the
figure were stunningly accurate, though, exact even to individual eyelashes and
stray strands of hair. Were it not for the monochrome tint, and the huge
sizethe figure was nearly twenty meters tall alreadyit might have been easily
mistaken for the girl herself. At the moment the shapely mouth was even working
in slow pulsations that were a horrible parody of speech.
Norah screamed hysterically. The figure
had seen Paul, and it appeared to recognize him, for it bent toward the
cowering geologist, the huge arms reaching out.
"P-P-A-U-L-L-L!" The
deafening shout was hardly recognizable, being more like a drawn-out, modulated
groan, than a true voice. Then the ebony shape swayed unsteadily and tried to
take a step forward. But its misshapen feet and legs would not leave the salt.
"Jeanne!" Paul Culkin
shouted suddenly, his eyes wild. He tried to run toward the groping arms, but
McCormick seized his arm and pulled him back, with Norah's help. The geologist
struggled all the while, but they retreated, shambling backward toward the buggy,
whose lights glowed steadily in the darkness of the grotto like the last
gleamings of sanity in a world gone mad.
Norah was babbling by the time
they reached the open hatch and shoved Culkin inside.
"Go around to the rear and
open the center hatchway," McCormick ordered sharply. When Norah didn't
reply he shook her violently and repeated the command. This time she nodded
weakly and hurried off.
Soon he was passing Culkin back
through the center bulkhead, making room so that he could get to the buggy
controls. "Take care of him," he told the girl, at last, and squirmed
around until he faced the port. Carefully he closed the hatch, then started up
the buggy and turned it, spinning the wheel so sharply that the vehicle rose up
on its port tires and almost rolled over on the salt. Then he shot for the
distant ramp at half acceleration.
Behind, in the mirrors, he could
see the giant figure leaning after them, striving to lift its huge feet and
failing; its voice thundering off the grotto walls until the entire chamber
rang like a vast bell with a voice of pure anguish.
It was too much. With a tiny cry
of fear McCormick leaned on the throttle control and the buggy began to whine
under full acceleration, heading for the surface . . . and sanity.
13.
They were gone! Jeanne Alexander
watched the last pale gleam of light go dim and vanish. Darkness swallowed up
the grotto, a darkness tinged with red, for the salt and lower walls were alive
with infrared radiation. Once again the girl tried to move. Her right foot
lifted slightly this time. Cords tore and she felt a brief twinge of pain, but
with the pain came relief. She wasn't trapped in the salt! That had been her
greatest fear.
She swayed with the struggle to
free her left foot. It lifted sluggishly. The binding cords snapped abruptly,
and a plume of steaming lava squirted up through one of the deep channels bored
through the salt. The scant alien memories in her brain identified the cords as
thermopods, and the paired image of a dielectric heat engine swelled in her
mind. They were necessary to life. Without them she would lapse into
unconsciousness and die, for her mass was far too great, her brain far too
demanding of energy for her to be able to subsist in the old ways. The feast of
the buggy had presented her with a rich store of energy, that which had been
trapped in its powercells, but now she would have to find an alternative to the
thermopods . . . and quickly if she wished to live.
Did she? Of course! It was a
foolish question.
Carefully, haltingly, as if a
newborn, she began to totter massively toward the ramp. Beyond it lay the
surface, the sun, but most importantly, her own kind.
Paul had tried to come to her, she
had seen that. But McCormick, damn him, had stopped the boy. Well, she'd fix
him, and that catty little Norah as well. At the moment she felt chipper enough
to take on the entire Noctis Lacus settlement, and as she began to stride up
the steep incline of the ramp her lips tightened purposefully. There was a
whole planet over her head; a rich red ball hanging temptingly in space like an
apple. Maybe it was time she took a bite out of it!
