The Invisible Man

: Gold In The Sky

Crouching back into the shadow, Tom Hunter waited as the heavy footsteps

moved up the corridor, then back down, then up and down again. He peered

around the corner for a moment, looking quickly up and down the curving

corridor. The guard was twenty yards away, moving toward him in a slow

measured pace. Tom jerked his head back, then peered out again as the

footsteps receded.



The guard was a big man, with
heavy-duty stunner resting in the crook

of his elbow. He paused, scratched himself, and resumed his pacing. Tom

waited, hoping that something might distract the big man, but he moved

stolidly back and forth, not too alert, but far too alert to risk

breaking out into the main corridor.



Tom moved back into the darkened corridor where he was standing, trying

to decide what to do. It was a side corridor, and a blind alley; it

ended in a large hatchway marked HYDROPONICS, and there were no

branching corridors. If he were discovered here, there would be no place

to hide.



But he knew that he could never hope to accomplish his purpose here....



A hatch clanged open, and there were more footsteps down the main

corridor as a change of guards hurried by. There was a rumble of voices,

and Tom listened to catch the words.



"... don't care what you think, the boss says tighten it up...."



"But they got them locked in...."



"So tell it to the boss. We're supposed to check every compartment in

the section every hour. Now get moving...."



The footsteps moved up and down the corridor then, and Tom heard hatches

clanging open. If they sent a light down this spur ... he turned to the

hatch, spun the big wheel on the door, and slipped inside just as the

footsteps came closer.



The stench inside was almost overpowering. The big, darkened room was

extremely warm, the air damp with vapor. The plastic-coated walls

streamed with moisture. Against the walls Tom could see the great

hydroponic vats that held the yeast and algae cultures that fed the crew

of the ship. Water was splashing in one of the vats, and there was a

gurgling sound as nutrient broth drained out, to be replaced with

fresh.



He moved swiftly across the compartment, into a darkened area behind the

rows of vats, and crouched down. He heard footsteps, and the ring of

metal as the hatchway came open. One of the guards walked in, peered

into the gloom, wrinkled his nose, and walked out again, closing the

hatchway behind him.



It would do for a while ... if he didn't suffocate ... but if this ship

was organized like smaller ones, it would be a blind alley. Modern

hydroponic tanks did not require much servicing, once the cultures were

growing; the broth was drained automatically and sluiced through a

series of pipes to the rendering plant where the yeasts could be

flavored and pressed into surrogate steaks and other items for spaceship

cuisine. There would be no other entrances, no way to leave except the

way he had come in.



And with the guards on duty, that was out of the question. He waited,

listening, as the check-down continued in nearby compartments. Then

silence fell again. The heavy yeast aroma had grown more and more

oppressive; now suddenly a fan went on with a whir, and a cool draft of

freshened reprocessed air poured down from the ventilator shaft above

his head.



Getting into the orbit-ship had been easier than he had hoped. In the

excitement as the new prisoners were brought aboard, security measures

had been lax. No one had expected a third visitor; in consequence, no

one looked for one. Huge as it was, the Jupiter Equilateral ship had

never been planned as a prison, and it had taken time to stake out the

guards in a security system that was at all effective. In addition,

every man who served as a guard had been taken from duty somewhere else

on the ship.



So there had been no guard at the airlock in the first few moments after

the prisoners were taken off the Ranger ship. Tom had waited until the

ship was moored, clinging to the fin strut. He watched Greg and Johnny

taken through the lock, and soon the last of the crew had crossed over

after securing the ship. Presently the orbit-ship airlock had gone dark,

and only then had he ventured from his place of concealment, creeping

along the dark hull of the Ranger ship and leaping across to the

airlock.



A momentary risk, then, as he opened the lock. In the control room, he

knew, a signal light would blink on a panel as the lock was opened. Tom

moved as quickly as he could, hoping that in the excitement of the new

visitors, the signal would go unnoticed ... or if spotted, that the

spotter would assume it was only a crewman making a final trip across to

the Ranger ship.



But once inside, he began to realize the magnitude of his problem. This

was not a tiny independent orbit-ship with a few corridors and

compartments. This was a huge ship, a vast complex of corridors and

compartments and holds. There was probably a crew of a thousand men on

this ship ... and there was no sign where Greg and Johnny might have

been taken.



He moved forward, trying to keep to side corridors and darkened areas.

In the airlock he had wrapped up his pressure suit and stored it on a

rack; no one would notice it there, and it might be handy later. He had

strapped his father's gun case to his side, some comfort, but a small

one.



Now, crouching behind the yeast vat, he lifted out the gun, hefted it

idly in his hand. It was a weapon, at least. He was not well acquainted

with guns, and in the shadowy light it seemed to him that this one

looked odd for a revolver; it even felt wrong, out of balance in his

hand. He slipped it back in the case. After all, it had been fitted to

Dad's hand, not his. And Johnny or Greg would know how to use it better

than he would.



If he could find them. But to do that, he would have to search the ship.

He would have to move about, he couldn't just wait in a storage hold.

And with all the guards that were posted, he would certainly stumble

into one of them sooner or later if he tried leaving this spot....



He shook his head, and started for the hatch. He would have to chance

it. There was no way to tell how much time he had, but it was a sure bet

that he didn't have very long.



In the spur corridor again, he waited until the guard's footsteps were

muffled and distant. Then he darted out into the main corridor, moving

swiftly and silently away from the guard. At the first hatchway he

ducked inside, waited in the darkness, panting....



The guard had stopped walking. Then his footsteps resumed, but more

quickly, coming down the corridor. He stopped, almost outside the

hatchway door. "Funny," Tom heard him mutter. "I'd have sworn...."



Tom held his breath, waiting. This was a storage hold, but he didn't

dare to move, even to take cover. The guard stood motionless for a

moment, then grunted, and resumed his slow pacing.



When he had moved away Tom caught his breath in huge gasps, his heart

beating in his throat. It was no use, he thought in despair. Once or

twice he might get away with it, but sooner or later a guard would be

alert enough to investigate an obscure noise, a flicker of movement in

the corner of his eye....



There had to be another way. His eye probed the storage hold,

hopelessly, and then stopped on a metal grill in the wall.



For a moment, he didn't recognize what it was. Then there was a

whoosh-whoosh-whoosh as a fan went on, and he felt cool air against

his cheek. He held out his hand to the grill, found the air coming from

there.



A ventilation shaft. Every space craft had to have reconditioning units

for the air inside the ship; the men inside needed a constant supply of

fresh oxygen, but even more, without pumps to move the air in each

compartment they would soon suffocate from the accumulation of carbon

dioxide in the air they breathed out, or bake from the heat their bodies

radiated. On the other hand, the yeasts and algae required carbon

dioxide and yielded copious amounts of oxygen as they grew.



In Roger Hunter's little orbit-ship the ventilation shafts were small, a

loose network of foot-square ducts leading from the central pumps and

air-reconditioning units to every compartment in the ship. But in a ship

of this size....



The grill was over a yard wide, four feet tall. It started about

shoulder height and ran up to the overhead. The ducts would network the

ship, opening into every compartment, and no one would ever open them

unless something went wrong.



And then he was laughing out loud, working the grill out of the slots

that held it to the wall, trying to make his hands work in his

excitement.



He knew he had found his answer.



The grill came loose, lifted down in a piece. He stopped short as

footsteps approached in the corridor, paused, and went on. Then he

peered into the black gaping hole behind the grill. It was big enough

for a man to crawl in. He shinned up into the hole, and pulled the grill

back into its slot behind him.



Somewhere far away he heard a throbbing of giant pumps. There was a rush

of cool fresh air past his cheek, cold when it contacted the sweat

pouring down his forehead. He could not quite stand up, but there was

plenty of room for him to crouch and move.



Ahead of him was a black tunnel, broken only by a patch of light coming

through the grill that opened into the next compartment. He started into

the blackness, his heart racing.



Somewhere in the ship Johnny Coombs and Greg Hunter were

prisoners ... but now, Tom knew, there was a way to escape.



* * * * *



It was a completely different world, a world within a world, a world of

darkness and silence, of a thousand curving and intersecting tunnels,

some large, some small. For hours it seemed to him that he had been

wandering through a tomb, moving through the corridors of a dead ship,

the lone surviving crewman. There was some contact with the other world,

of course, the world of the spaceship outside ... each compartment had

its metal grill, and he passed many of them. But there were like doors

that only he knew existed. He met no one in these corridors, there was

no danger of sudden discovery and arrest in these dark alleys....



His boots had made too much noise as he started out, so he had slipped

them off, hanging them from his belt and moving on in his stocking feet.

As he went from duct to duct, he had an almost ridiculous feeling of

freedom and power. In every sense, he was an invisible man. Not one soul

on this great ship knew he was here, or even suspected. He had the run

of the ship, complete freedom to go wherever he chose. He could move

from compartment to compartment as silently and invisibly as if he had

no substance at all.



* * * * *



He knew the first job was to learn the pattern of the ducts, and

orientation was a problem. He had heard stories of men getting lost in

the deep underground mining tunnels on Mars, wandering in circles for

days until their food gave out and they starved. And there was that

hazard here, for every duct looked like every other one.



But there was a difference here, because the ducts curved just as the

main ship's corridors did. He could always identify the center of the

ship by the force of false gravity pulling the other way. Furthermore,

as the ducts drew closer to the pumps and reconditioning units, they

opened into larger vents, and the noise of the pumps thundered in his

ears. After an hour of exploration, Tom was certain that from any place

in the ship he could at least find his way to the outer layer, and from

there to one of the scout-ship airlocks.



Finding Greg and Johnny was quite a different matter.



He could not see enough through the compartment grills to identify just

what the compartments were; he was forced to rely on what he could hear.

The engine rooms were easily identified. In one area he heard the

banging of pots and pans, the steaming of kettles ... obviously the

galley. He found the control area. He could hear the clatter of typing

instruments, the click-click-click of the computers working out the

orbits and trajectories for the scout-ships as they moved out from the

orbit-ship or came back in. In another compartment he heard a dispatcher

chattering his own special code-language into a microphone in a

low-pitched voice. He passed another grill, and then stopped short as a

familiar voice drifted through.



Merrill Tawney's voice.



Tom hugged the grill, straining to catch the words. The company man

sounded angry; the man he was talking to sounded even angrier. "I can't

help what you want or don't want, Merrill, I can only report what we've

found, and that's nothing at all. Every one of those claims has been

searched twice over. Doc and his boys went over them, and we didn't find

anything they missed. I think you're barking up the wrong tree."



"There's got to be something," Tawney said, his voice tight with

anger. "Hunter couldn't have taken anything away from there, he didn't

have a chance to. You read the reports..."



"I know," the other said wearily, "I know what the reports said."



"Then what he found is still there. There's no other possibility,"

Tawney said.



"We went over that rock with a microscope. We blew it to shreds. Assay

has gone through the fragments literally piece by piece. They found low

grade iron, a trace of nickel, a little tin, and lots of granite. If we

never found anything richer than that, we'd have been out of business

ten years ago."



There was a long silence. Tom pressed closer to the grill. Then he heard

Tawney slam his fist into his palm. "You know what Roger Hunter's doing,

don't you?" he said. "He's making fools of us, that's what! The man's

dead, and he's making us look like idiots. If we hadn't been so sure we

had the lode spotted ..." He broke off. "Well, that's done, we can't

undo it. But this brat of his...."



"Any luck there?"



"Not a word. He's playing coy."



"Maybe he doesn't know anything. Doc made a bad mistake when he blasted

the other one ... suppose he was the only one that knew."



"All right, it was a mistake," Tawney snapped. "What was he supposed to

do, let him get back to Mars? We've got a good front there, but it's not

that good. If the United Nations gets a toehold out here, the whole Belt

will go into their pocket, you realize that. They're waiting for us to

make one slip." He paused, and Tom heard him pacing the compartment.

"But I think we've got our boy. This one knows. We've been spoiling him

so far, that's all. Well, now we start digging. When I get through with

him, he'll be begging us to let him tell. You just watch me, as soon as

the okay comes through...."



Tom drew back from the grill, moving on in the darkness. So far he had

not rushed his exploration ... there was a chance to use the ducts for

escape, he wanted to know them well. But now he knew the hour was

getting late. So far Greg and Johnny had been stalling Tawney ... but

Tawney was getting impatient.



He moved quickly and he thought again of what Tawney had said. Tawney

was right about one thing ... there was no way that Dad could have

hidden a Big Strike so nobody could find it. It had to be there....



And yet it wasn't. He and Greg hadn't found it. Tawney's men hadn't

found it, either. Why not? There must be a reason.



But he could not put his finger on it.



Half an hour later he was seriously worried. Half the compartments in

the area were deserted, the men leaving for the cafeteria. The thought

reminded Tom how hungry he was, and thirsty. His small emergency ration

kit was empty. He toyed with the thought of sneaking into a food storage

compartment, then thrust it out of his mind as too risky. He had to find

Greg and Johnny before anything.



He passed a grill, and heard a murmur of voices; something in the deep

bass rumble caught his ear, and he stopped, listened.



The voices stopped also.



He waited for them to begin, pressing against the grill. Johnny Coombs

was not the only man with a deep bass voice, he might have been

mistaken. He listened, but there was no sound. He heard the whir of a

fan begin, still no sound, not even footsteps.



And then it happened, so fast he was taken completely off guard. The

grill suddenly gave way, pitching him forward into the compartment.

Something struck him behind the ear as he fell; there was a grunt, a

sharp command, and he was pinned to the floor in the semi-darkness of

the compartment.



Then he heard a gasp, and he opened his eyes. He was staring into his

brother's startled face. Greg was pinning his shoulders to the carpeted

deck, and behind him Johnny Coombs had a fist raised....



But they had stopped in mid-air, like a tableau of puppets. Greg gaped,

his jaw falling open, and Tom heard himself saying, "What are you trying

to do, kill a guy? Seems to me one time is enough."



He had found them.
