Part 1

BENEATH THE RED WORLD'S CRUST

By Erik Fennel

The ancient leviathan heaved mightily in the vast buried cavern, pumping water upward as it had been told. Only hunted Nick Tinker knew that more than just water was coming to the dust-dry surface!

The hot, high whine scorched past his face and the slug splatted into the eroded grey wall beside him. He should have died then, but his instinctive recoil at feeling something sticky and moist beneath his feet saved him.

Nick Tinker let himself crumple and fall, a trick which during the War days back on Earth had fooled more than one sniper. His left hand slid under his padded jacket toward his gun, but the movement looked as though he were clutching his chest. His right arm landed outstretched, and he let that hand clutch convulsively at the air. Then he lay very still beneath the unwinking Martian stars while the thin, chilling night wind whispered through the deserted, sand-drifted streets.

The Gravinol was gradually leaving his brain, leaving him feeling fully alive for the first time since he had entered the Special Corps back on Earth at the age of seventeen. He wasn't sure he liked being so completely alive, for it was all he could do to keep his body from cringing under the expectation of another, better-aimed bullet. The stoic fatalism was gone.

He lay motionless, but his trained senses were busily sorting the eerie impressions of this undead Martian city, picking out a sensation of--someone watching. The feeling localized itself on an oval opening in the hulking black building across the wide street. His gun hand moved imperceptibly and his jacket tore and smoldered as he fired. The recoil slide of the heavy automatic thumped a bruise against his ribs, and even as the explosive bullet flared against the window's edge he was on his feet, zigzagging across the street in a stooping rush to flatten himself against the wall.

He watched the greenish light of a glow-plate seeping from the window, hoping for a glimpse of the sniper's silhouette. The window had been dark before, but his bullet had evidently damaged the screen-creature that covered the window. He knew the screen-creatures well, the living, amorphous and deadly remnants of a Martian civilization that still guarded almost every opening in this abandoned city, rendering it so hazardous for unwary Earthmen.

His groping hands found the narrow entrance to the building and he ducked in. Someone had been there before him, and recently, for the door-creature inside the alcove hung in tattered shreds. One of its torn, limp folds touched his hand as he passed, and with a sudden resurgence of alien life it contracted around his wrist. It tried to unleash its deadly shock, but it was weak and Nick felt only a faint tingle.

He jerked free and went up the inside ramp at a fast but quiet run, his finger ready on the trigger as he neared the top.

Then Nick stopped dead as he saw his target. The girl looked hardly more than a child. Her tattered blouse was pulled aside and she was mopping blindly at a bleeding gash low on one shoulder. The back of her other hand scrubbed at her closed eyes. Her face, framed in uncombed coppery hair, was peppered with grey freckles of rock dust thrown by Nick's explosive bullet.

His boots gritting in the dust, warned her, for she whirled, opening red-rimmed, watering eyes and snatching up a heavy rifle.

It would have been an easy shot, but Nick did not fire.

* * * * *

Her rifle spat once into its silencer as he dived across the room and they went to the floor together. For a minute he was fully occupied in avoiding her teeth and fingernails and shrewdly placed kicks as she fought with the desperation of terror, but at last he got a grip on her hair and clipped her once on the point of the chin.

He spat out a mouthful of acrid dust and tore the remains of her blouse into strips. There was haste and no gentleness in the way he tied her hands and feet. The exertion left him panting in the thin Martian air, so he took a breath of oxygen from his pocket sniffer bottle. Then, wanting to talk to the girl at once, he held the nosepiece to her face.

He knew when she recovered consciousness, for her head twisted suddenly and her teeth sank into his hand. He slapped her face hard, and she lay staring up at him with hatred and terror.

"You're Susan Jones," he declared.

"Murderer!" she spat, her face twisted with loathing.

He followed her glance to his uniform and laughed mirthlessly. "I'm outlawed," he snorted. "The Mec is after me just as hot as they're after you. I disobeyed orders."

She looked at him unbelievingly, suspecting some sort of trap. She knew from experience the ruthless resourcefulness of the Martian Exploitation Company.

"You couldn't disobey," she said incredulously. "You couldn't."

"Like hell," he snapped. "I've had no Gravinol for six weeks. Now, where's your father?"

His temper flared as her lips set in a stubborn line. He had no time to lose.

"I'll make you talk, damn you!"

The rush of treads and whine of brakes from the street interrupted him, sending him to the window with gun ready. The screen-creature, still alive with the almost unkillable vitality of those alien things, had dragged itself together to cover the opening again. Nick was careful not to touch it. He peered out, knowing that to the men climbing from the armored half-track the window would appear dark. The screen-creatures passed light in one direction only. As quietly as possible he closed the sliding panel at the top of the ramp and pushed in the locking plug.

"Remember, get the old man alive. Stun him if necessary, but alive. That's orders from The Man himself." Nick recognized Colonel Hammer's voice. The search must be tightening if the commandant himself took charge of a patrol. They were after Professor Jones and his daughter, but Nick knew that he too would be shot on sight. This time he was with the hunted instead of the hunters.

The girl's face went white as he drew his sheath knife. Then she stared uncomprehendingly as the blade slit her bonds instead of her throat.

"Over the roofs," he whispered. "Which way out?"

She pointed, still uncertain of his intentions.

A big man in a uniform like Nick's own lay sprawled on the floor of the adjoining room, a black circle between his eyes. Nick spared him just one glance. And then he understood the sticky-moist splotch he had encountered in the street. The man with the straggly beard had caused it, bleeding his life away through the gaping rent in his chest.

The girl ignored Nick's ready pistol and ran to the low couch on which the old man reclined. "Dad!" she called softly, shaking his shoulder. "Dad!"

Nick pulled her away and shook his head. Jackson Jones, the first man to reach Mars, was dead.

"Shoot that panel down!" someone yelled from the ramp. "He's in there!"

"Wanna get took by the back-blast?" another voice complained. "Stand back."

"Which way?" Nick asked quietly.

The girl darted to a window and Nick caught his breath as she reached toward the guarding screen-creature. Then he stared for, instead of killing her with its strange powers, the rubbery, no-color, living stuff flowed back into grooves in the edge of the stone. Susan gave one last backward glance at her father's body and scrambled through.

Nick followed nervously and sprawled beside her on a narrow roof ledge. She touched the screen-creature again and it closed with a silent, oily motion.

"It felt my thoughts," she whispered.

He dragged her to her feet and they ran through the dim starlight, climbing across the uneven roofs, leaping the chasms between buildings in the darkness. Excited yells as the patrol broke through the panel and found the two bodies speeded them onward. The girl held her own, keeping the fast pace Nick set, although a few times he had to help her swing her slender body from a lower roof to a higher one.

"Down!" he barked suddenly. A jet of orange light flung itself upward and outward behind them as someone turned a flame gun on the window through which they had escaped.

"There she is!"

An automatic roared a long burst. From a roof in the opposite direction from where they crouched behind a projecting cornice a _cajora_ screamed as it tumbled, astonishingly like a woman in agony.

"You got her, Fred!" someone yelled triumphantly. "Nice shooting!"

Susan shivered, not entirely from the cold.

"What now?" she asked.

"Hide."

* * * * *

The pause had given Nick time to get his bearings. Searchlights from a dozen cars were lancing through the city, and he knew they had to get under cover before flares flooded the roofs with brilliance. He found the hole in which he had hidden during the day, a spot of deeper blackness beneath an overhanging ledge, and motioned Susan inside.

Instead of following immediately he belly-crawled to the edge of the flat roof. Two armored cars were approaching, still hidden from each other by the curving street, but he could see them both.

Anger at his pursuers burned fiercely inside him, anger and the deep-seated prejudice against purely defensive action that was a legacy from the Special Corps days on Earth.

Smiling grimly, he unslung the rifle he had taken from the girl and sent a single bullet ricocheting harmlessly off the turret of each car.

Then he followed Susan. Even through the massive stone walls of the building they could hear the whistling roar of two proton cannon--firing at each other. Colonel Hammer would be displeased with the survivors, Nick reflected with grim amusement.

They paused just inside the black hole to let their labored breathing return to normal. It seemed to go right through the building, between inner and outer shells.

"We'd better climb down and hope it goes deep enough," he said at last. The Martian Exploitation Company had a little gadget, outgrowth of the last War on Earth, which could detect the presence of living creatures through a hundred feet of solid rock.

"This passage will join the tunnels," the girl said with quiet confidence. "We can dodge their detectors."

"What tunnels? You been here?" he asked sharply, trying to see her face in the blackness.

"No, but a _vora_ made this."

Nick didn't understand, but there was no time for hesitation. They climbed down, into an underworld of blackness and silence. He went first, searching out niches in the almost vertical shaft with his toes, lowering his body, reaching overhead to guide Susan's feet. Once one of them dislodged a sliver of rock that bounced and clicked into the depths for what seemed like minutes. His mind was seething with questions but the treacherous shaft required his full attention.

Only the light gravity of Mars made the climb possible, and even then his muscles were stiff and aching when at last his feet touched a solid floor and they sprawled in what the echoes of their heavy breathing told them was a roughly horizontal tunnel. He estimated they had come at least a mile straight downward, perhaps more.

For a long time they lay without moving in the powder-fine sand that had penetrated even here.

"We've got to steal a ship," he voiced the thought uppermost in his mind. Already he had accepted this girl as a partner in his venture, for she too was a fugitive from the tyranny of the Martian Exploitation Company.

Her body jerked suddenly at his words, and then he had to fumble for her in the darkness and shake her with brutal insistence until her hysterical laughter stopped.

"Just steal a ship!" she gasped finally, her voice still unsteady. "Dad and I tried for a year, ever since the Exploiters came and wrecked our _Trailblazer_. And now they've killed him!" She began to sob, but this time in sadness rather than hysteria.

Nick was frantic for the missing fragments of the puzzle, but he knew it would be useless to question her now. She began to shiver in the chill, so he removed his torn jacket and slipped it around her naked shoulders. After a while she sobbed herself to sleep, too exhausted and grief-stricken to care any more what happened to her.

Nick dozed too, but the dregs of Gravinol still in his system denied him the release of complete forgetfulness. In disconnected, nightmarish flashes his mind reviewed the chain of events that had made him a hunted outlaw upon an alien planet.

There was a bittersweetness to his thoughts of Earth, a nostalgic homesickness for the planet of great cities and green foliage and free-flowing water it had been before the War--and might some day be again.

And then the War itself. The boyish, unthinking enthusiasm with which he had enlisted in the Special Corps. The new drug, Gravinol, touted by the laboratories of the great Harmon Enterprises as the discovery that would win the War. Twisting, writhing rocket fights high above the atmosphere, pilots of the Corps immersed in hypnotic, Gravinol-induced blind loyalty to the Cause, immune to fatigue and pain and fear.

City after city crumbling to atomic dust. Rocket bases blasted out of existence and no more targets worth bombing. Complex weapons giving way to more primitive ones as industrial systems broke down. The Special Corps transferred from air to ground duty. Crumbling battle lines, disintegration of organized warfare into deadly confusion in which friend and foe were indistinguishable.

* * * * *

Peace. Peace without victory, without decision. Peace of destruction. Battles dying into scattered skirmishes that eventually died of their own inertia. Disillusion and disgust. But it was peace.

Realization that Gravinol, hurriedly released upon the world without proper testing, was incompatible with any civilized system and at the same time incurably habit forming. Gravinol outlawed by the reviving New Governments. The few hundred survivors of the Special Corps, Nick among them, roaming the face of Earth in a desperate, frustrating search for the few grams still in existence, ready to commit any crime to ease their torment, clinging with fanatical, drug-inculcated loyalty to a Cause that had died with the War's end, looking endlessly for a new Cause to which to fasten their drug-inflamed energies, shunned and avoided and feared and hated by those persons not in the grip of Gravinol.

The whispered rumor that had led him to that office, miraculously untouched amid the ruins of Chicago. Listening to the young man with the cold eyes--he had never learned his name--as he told of the Jones Drive and the double Cause of protecting Earth and making Mars a fit new world for human colonization.

"And this," the man had said, casually rolling a tiny red pellet of Gravinol across the broad desk into Nick's clutching fingers. "All you want."

Central Camp, the Martian Exploitation Company's base on the red desert, and indoctrination under the thought machines. Plenty of Gravinol, to be had for the asking, and the companionship of other old members of the Corps. Flashing out in a wonderfully responsive fighter rocket to strafe and destroy a skulking Martie or two. Months without unhappiness, without a single emotional response not conditioned by the Gravinol and the thought machines.

Then one night the glow of a spaceship landing far to the East, and Colonel Hammer's orders.

"That ship is not authorized by Headquarters. Bomb it! And you, Tinker, photograph the results. The Man wants proof."

Silvery hull against red sand. Small derrick drilling for the water Nick knew they would never find, for even the Exploiters had failed. A few tents. Men and women and half a dozen children waving excited greetings. Ship and tents obscured as the bombs detonated. And when the dust cleared--nothing.

Liquidation of the potential independent colony had made no impression at the time, but now in this tunnel far beneath the surface Nick clenched his fists and bit his lip as he thought of the callous brutality of it.

* * * * *

Then, weeks afterward, that card game quarrel with Jake Alaimo. Patrol the next day, and rockets failing far out over the bleak and deadly desert. Fuel gauges showing full but tanks empty, radio dead, and Alaimo's note on the mechanic's service card.

Starting the impossibly long walk back to base. Eyes tortured by the harsh sunlight. Thirst. Beginnings of the gnawing craving for Gravinol.

Memories of the tortures he had endured brought Nick wide awake in the tunnel, all his muscles tightening momentarily as though to begin the twitching spasm typical of denied Gravinol addiction.

He seemed to remember collapsing in the shadow of a rocky outcropping, and as he had fainted he had known he was dying. He had been so near dead that his eyes remained vacantly open, and in his unconsciousness he had seen--he thought--strange creatures that were tall and green and somehow _thin_ in consistency. Like Marties. And there had been darkness and coolness after the blazing heat of the desert. Yes, and even wetness, wetness on arid Mars where all water was tanked in from Earth. He couldn't remember, but something had happened.

Days later a patrol had found him by chance, and back at Central Camp the medical staff had been skillful. But they were human and had therefore overlooked the obvious fact that he had gone three weeks without Gravinol. And for some reason he himself could not understand he had remained silent, battling the recurrent temptation as he recovered. Something--perhaps bodily dehydration, perhaps heat, perhaps the actinic rays of the sun that had turned his skin almost to leather--something out there on the desert had enabled him to evade the death that usually followed deprivation of Gravinol.

One day when he was stronger and the recurring craving had all his nerves screaming, he had called Jake Alaimo out for a barehanded duel and snapped his neck with an edgewise chop of his palm. But when Colonel Hammer had congratulated him he had only felt annoyance. He was beginning to think for himself once more.

II

A sound in the tunnel broke into his reverie, bringing him instantly to the alert. Soft padding footsteps. He drew his gun and aimed at the sound.

"Don't!" Susan's hand dragged his gun down. "It won't hurt us."

"Huh?" Indoctrination had taught that everything that moved upon Mars was hostile, to be killed on sight. The impulse was still strong.

"It's a _cajora_. The Martians keep them as pets," she insisted.

Nick's scalp crawled as the big animal glided through the darkness and its coarse fur made sandpaper sounds against Susan's legs. He had seen the six-legged beasts on the surface, large as Earth tigers.

"_Mel nikko twa Klev_," Susan said soothingly. "_Mel nikko twa Klev?_"

The creature purred.

Nick kept his gun ready and swung toward the girl. She could feel him tense with suspicion. Indoctrination had impressed upon Nick's mind the story that Jackson Jones and his daughter had turned traitor to Earth, siding in with the dangerous and degenerate Marties.

"What'd you say?" he asked.

"That's Martian." Her answer was matter-of-fact. "I asked him where Klev is."

"Martian?" Nick was astonished. "Have they a real language? Then they're really intelligent?" He had suspected but hadn't known.

"Of course," she whispered. "Ssh! You're disturbing the _cajora_."

"What's Klev? What do you want?"

"He's a Martian. My friend," she answered, and talked to the _cajora_ again as though it were a dog or cat.

"I think he understands," she said after a little. "Keep your hand on him and follow."

Nick was hesitant, but the only alternative was to remain in the pitch black, musty tunnel.

For hours they shuffled blindly along, their hands meeting in the loose fur of the beast's neck. The tunnel sloped downward, turning right and left so that within minutes Nick was hopelessly lost. Time and again his outstretched fingers, trailing along the wall, encountered the emptiness of side tunnels and branchings, but the _cajora_ moved purposefully ahead. Several times Nick tried to talk, to ask the questions which were perplexing him, but each time the girl silenced him.

"You'll distract the _cajora_," she warned.

The animal stopped short as they rounded a turn and saw a glimmer of light ahead.

"They don't like light," she explained. "We'll have to go on alone."

The light came from a cross tunnel, from patches of some glowing substance in the hard, smooth walls. The tunnel was roughly circular in section, large enough for Nick to walk upright despite his height.

He whistled in amazement.

"Who built these?" he asked, for they had come several miles in darkness and now the lighted tunnel stretched away into the distance, a major engineering project.

"The Martians."

"How?"

"With their _voras_."

He wanted to ask her to explain, but she was examining some markings on the walls, combinations of triangles and curved lines that were obviously writing. She seemed to understand them, and Nick began to understand now how she and her father had evaded the Mec patrols so long. The leaders of the Martian Exploitation Company did not even suspect the existence of this extensive underground labyrinth.

"We're a long way from Klev's home," the girl declared. "The faster we get there the better."

"Why? What's the danger? The Mecs won't follow us down here?"

"Martians."

"Huh? I thought you were friends with them."

She shook her head sadly.

"Only a few now. The rest have grown to hate us. Come on."

They had covered several more miles when they were stopped. Susan's faint gasp sent Nick's hand automatically to his holster and he looked up to see three Martians emerging from a side tunnel just ahead.

He stared. They were the first living Martians he had seen at really close range, and the bodies of those hunted down by the patrols had always been as crumpled and collapsed as spiders caught in the flame of a blowtorch.

* * * * *

They were slightly taller than humans, with great glowing eyes in their bulging heads and thin, many-fingered arms that reached almost to the knee joints of their stubby legs. Their noses were almost flat and their mouths too small, and their heads were topped by erect crests of skinlike material. Two of them were a dull greenish color, but the third, evidently the leader, had a marked bluish tinge to his face. All three wore shapeless brown clothing.

The three made no threatening move at first, but training and the habit of self-preservation were still strong in Nick. He raised his gun.

Before he could fire something uncoiled itself from the shoulders of the leading Martian and flapped down the tunnel like an ugly, distorted bat. It knocked him off balance as it struck his head and shoulders and clung there, heavy and warm and _alive_. Numbness raced through his body wherever it touched. His muscles refused to respond when he tried to squeeze the trigger and his struggles only brought part of the thing around his throat in a powerful, strangling grip.

Susan called out something in the same language she had used to the _cajora_ and took the pistol from his helpless fingers. But to his dismay she did not raise it.

The Martian made a chirping, almost inaudible sound and the thing relaxed its throttling grasp. Feeling began to return to Nick's arms. He could feel tiny pulsations running through the boneless, rubbery mass that still clung tightly to his shoulders.

Susan had made no move to help him. Now she cringed back at the look on his face, a look that spelled murder. He reached for her, but instantly his arms fell limp and numb again as the Martian chirped.

"You sold me out to these--these," he gritted. "You slimy little doublecrosser!"
