Sally said: "I don't think they know how the big brass thinks."

Haney and Joe said together, "No!" and Joe added: "Mike's not crazy! He

knows better! But it's a good story for somebody who doesn't know Mike."

Haney said in indignation: "I came out here to ask the Major to help us.

The Chief's gettin' a gang together, too. There's some Indians of his

tribe that work here. We can count on them for plenty of rough stuff.

And there's Joe and me. The point is that Mike's stunt makes it certain

that everything busts loose at a time we can know in advance. If the

Major gives us a free hand, and then in the last five minutes takes his

own measures--so they can't leak out ahead of time and tip off the gangs

we want to get--we oughta knock off all the expert saboteurs who know

the weak spots in the Platform. For instance those who know that

thermite in the gyros would mess everything up all over again."

Joe said quietly: "But Major Holt has to be told well in advance about

all this! That's absolute!"

"Yeah," agreed Haney. "But also he has got to keep quiet--not tell

anybody else! There've been too many leaks already about too many

things. You know that!"

Joe said: "Sally, see if you can get your father to come here and talk.

Haney's right. Not in his office. Right here."

Sally got up and went inside the house. She came back with an uneasy

expression on her face.

"He's coming. But I couldn't very well tell him what was wanted,

and--I'm not sure he's going to be in a mood to listen."

When the Major arrived he was definitely not in a mood to listen. He was

a harried man, and he was keyed up to the limit by the multiplied strain

due to the imminence of the Platform's take-off. He came back to his

house from a grim conference on exactly the subject of how to make

preparations against any possible sabotage incidents--and ran into a

proposal to stimulate them! He practically exploded. Even if provocation

should be given to saboteurs to lure them into showing their hands, this

was no time for it! And if it were, it would be security business. It

should not be meddled in by amateurs!

Joe said grimly: "I don't mean to be disrespectful, sir, but there's a

point you've missed. It isn't thinkable that you'll be able to prevent

something from being tried at a time the saboteurs pick. They've got

just so much time left, and they'll use it! But Mike's plan would offer

them a diversion under cover of which they could pull their own stuff!

And besides that, you know your office leaks! You couldn't set up a

trick like this through security methods. And for a third fact, this is

the one sort of thing no saboteur would expect from your security

organization! We caught the saboteurs at the pushpot field by guessing

at a new sort of thinking for sabotage. Here's a chance to catch the

saboteurs who'll work their heads off in the next twenty-four hours or

so, by using a new sort of thinking for security!"

Major Holt was not an easy man to get along with at any time, and this

was the worst of all times to differ with him. But he did think

straight. He stared furiously at Joe, growing crimson with anger at

being argued with. But after he had stared a full minute, the angry

flush went slowly away. Then he nodded abruptly.

"There you have a point," he said curtly. "I don't like it. But it is a

point. It would be completely the reverse of anything my antagonists

could possibly expect. So I accept the suggestion. Now--let us make the

arrangements."

He settled down for a quick, comprehensive, detailed plan. In careful

consultation with Haney, Joe worked it out. The all-important point was

that the Major's part was to be done in completely unorthodox fashion.

He would take measures to mesh his actions with those of Mike, the

Chief, Haney, and Joe. Each action the Major took and each order he gave

he would attend to personally. His actions would be restricted to the

last five minutes or less before shift-change time. His orders would be

given individually to individuals, and under no circumstances would he

transmit any order through anybody else. In every instance, his order

would be devised to mean nothing intelligible to its recipient until the

time came for obedience.

It was not an easy scheme for the Major to bind himself to. It ran

counter to every principle of military thinking save one, which was that

it was a good idea to outguess the enemy. At the end he said detachedly:

"This is distinctly irregular. It is as irregular as anything could

possibly be! But that is why I have agreed to it. It will be at

least--unexpected--coming from me!"

Then he smiled without mirth and nodded to Joe and to Haney, and went

striding away down the concrete walk to where his car waited.

Haney left a moment later to carry the list of arrangements to the Chief

and to Mike. And Joe went into the Shed to do his part.

There was little difference in the appearance of the Shed by night. In

the daytime there were long rows of windows in the roof, which let in a

vague, dusky, inadequate twilight. At night those windows were

shuttered. This meant that the shadows were a little sharper and the

contrasts of light and shade a trifle more abrupt. All other changes

that Joe could see were the normal ones due to the taking down of

scaffolding and the fastening up of rocket tubes. It was clear that the

shape of the Platform proper would be obscure when all its rocket tubes

were fast in place.

Joe went to look at the last pushpots, and they were ready to be taken

over to their own field for their flight test before use. There were

extras, anyhow, beyond the number needed to lift the Platform. He found

himself considering the obvious fact that after the Platform was aloft,

they would be used to launch the ferry rockets, too.

Then he moved toward the center of the Shed. A whole level of

scaffolding came apart and its separate elements were bundled together

as he watched. Slings lowered the bundles down to waiting trucks which

would carry them elsewhere. There were mixing trucks still pouring out

their white paste for the lining of the rocket tubes, and their product

went up and vanished into the gaping mouths of the giant wire-wound

pipes.

Presently Joe went into the maze of piers under the Space Platform

itself. He came to the temporary stairs he had reason to remember. He

nodded to the two guards there.

"I want to take another look at that gadget we installed," he said.

One of the guards said good-naturedly: "Major Holt said to pass you any

time."

He ascended and went along the curious corridor--it had handgrips on the

walls so a man could pull himself along it when there was no weight--and

went to the engine room. He heard voices. They were speaking a

completely unintelligible language. He tensed.

Then the Chief grinned at him amiably. He was in the engine room and

with him were no fewer than eight men of his own coppery complexion.

"Here's some friends of mine," he explained, and Joe shook hands with

black-haired, dark-skinned men who were named Charley Spotted Dog and

Sam Fatbelly and Luther Red Cow and other exotic things. The Chief said

exuberantly, "Major Holt told the guards to let me pass in some Indian

friends, so I took my gang on a guided tour of the Platform. None of 'em

had ever been inside before. And----"

"I heard you talking Indian," said Joe.

"You're gonna hear some more," said the Chief. "We're the first war

party of my tribe in longer'n my grandpa woulda thought respectable!"

Joe found it difficult to restrain a smile. The Chief took him off to

one side.

"Fella," he said kindly, "it bothers you, this business, because it

ain't organized. That's what this world needs, Joe. Everything figured

out by slide rules an' such--it's civilized, but it ain't human! What

everybody oughta be is a connoisseur of chaos, like me. Quit worryin'

an' get outside and pick up that security guy the Major was gonna send

to meet you!"

He gave Joe an amiable shove and rejoined his fellow Mohawks, each of

whom, Joe noticed suddenly, had somewhere on his person a twelve-inch

Stillson wrench or a reasonable facsimile to serve as a substitute

tomahawk. They grinned at him as he departed.

At the bottom of the flight of narrow wooden steps there was a third

security man. He greeted Joe.

"Major Holt told me to pick you up," he observed.

Joe walked to one side with him. Major Holt had promised to send a

first-class man to meet Joe at this place, with orders to take

instructions from Joe. Joe said curtly: "You're to snag as many Security

men as you can, place them more or less out of sight under the Platform

here, and tell them to turn off their walkie-talkies and wait. No matter

what happens, they're to wait right here until they're needed, right

here!"

He looked harassedly around him. The Security man nodded and moved

casually away. This was close timing. Something made Joe look up. He saw

the catwalk gallery nearly overhead. The expected guard was there.

Haney, though, was with him. There was nothing else in sight. Not yet.

But Haney was on the job. Joe saw a Security man step out of sight in

the scaffolding. He saw his own assigned security man speak to another,

who wandered casually toward the Platform's base.

Minutes passed. Only Joe could have noticed, because he was watching for

it. There were eight or nine Security men posted within call. They had

their walkie-talkies turned off and would be subject only to his orders

if an emergency arose.

Gongs began to ring all around the edge of the Shed. They set up a

horrendous clanging. This was not an alarm, but simply the notice of

change-of-shift time.

There was a marked change in the noises overhead. A crane pulled back.

Hammerings dwindled and stopped. There were the sounds of pipes,

combined to form the scaffolds, being taken apart for removal. A

sling-load of pipe touched the floor and stayed there. The crane's

internal-combustion motor stopped. Its operator stepped down to the

floor and headed for the exit. Hoists descended and men moved across the

floor. Other men scrambled down ladders. The floor became dotted with

figures moving toward the doors through which men went out to get on the

busses for Bootstrap.

Nothing happened. More long minutes passed. The shift brought out by the

busses was going through the check-over process in the incoming screen

room. Joe knew that Major Holt had, within the past five minutes,

gathered together a tight-knit bunch of armed security men to be

available for anything that might turn up. The men doing the normal

shift-change screening were shorthanded in consequence.

The floor next to the exits became crowded, but the central area of the

floor was cleared. One truck was stalled at the swing-up truck doors.

Its driver ground the starter insistently.

Suddenly there was a high-pitched yell away up on the Platform. Then

there was a shot. Its echoes rang horribly in the resonant interior of

the Shed. Joe's own special security man hurried to him, his face tense.

"What about that?"

"Hold everything," said Joe grimly. "That's taken care of."

It was. That was Mike's gang--miniature humans popping out of hiding to

offer battle with missiles carefully prepared beforehand against their

alleged associates in sabotage. One of the associates had drawn a gun

and fired. But Mike's gang had help. Out of small air locks devised to

make the Platform's skin accessible to its crew on every side--provided

they wore space suits--dark-skinned men appeared.

The security man's walkie-talkie under his shoulder made a buzzing

sound. He reached for it.

"Forget it!" snapped Joe. "That's not for you! You've got your orders!

Stay here!"

There was a sudden growling uproar where men were crowding to get out of

the Shed. Thick, billowing smoke appeared. There was a crashing

explosion. The men eddied and milled crazily.

The motor of the stalled truck caught. It moved toward the door, which

opened, swinging up and high. Two trucks came roaring in. They raced for

the Platform. And as they raced inside, their camouflaged loads

clattered off and men showed instead. The guards by the doorway began to

shoot.

"That's what we've got to stop!" snapped Joe.

He began to run, his pistol out. There was suddenly a small

army--gathered by his orders--which materialized in the dim space under

the Platform. It raced to guard against this evidently well-planned

invasion.

The harsh, tearing rattle of a machine gun sounded from somewhere high

up. Joe knew what it was. Mike's whole scheme had been intended to force

all sabotage efforts to take place at a single instant. Part of the

preparation was authority for Haney to drag in two machine guns from an

outer watching-post and mount them to cover the interior of the Shed

when the general attack began.

Those machine guns were shooting at the trucks. Splinters sprang up from

the wood-block floor. Then, abruptly, one of the trucks vanished in a

monstrous, actinic flash of blue-white flame and a roar so horrible that

it was not sound but pure concussion. The other truck keeled over and

crashed from the blast, but did not explode. Men jumped from it. There

must have been screamed orders, but Joe could hear nothing at all. He

only saw men waving their arms, and others seized things from the

toppled load and rushed toward him, and he began to shoot as he ran to

meet them.

Now, belatedly, the sirens of the Shed screamed their alarm, and choppy

yappings set up as the siren wails rose in pitch. Over by the exit

pistols cracked. Something fell with a ghastly crash not ten feet from

where Joe ran. It was a man's body, toppled from somewhere high up on

the structure that was the most important man-made thing in all the

world. A barbaric war whoop sounded among the echoes of other tumult.

A Security man shot, and one of the running figures toppled and slid,

his burden--which must certainly be a bomb--rolling ridiculously. There

had been two trucks that plunged through the swing-up door. They had

raced for the spaces under the Platform at the exact time when the floor

would be clear, because all work had stopped. Under the Platform, the

trucks were to have been detonated. At the very least, they would have

rent and torn it horribly. They might have broken its back. And surely

one truck should have made it. But there should not have been machine

guns ready trained to shoot. Now the load of desperate men from the

overturned survivor scurried for the Platform with parts of its cargo.

If they could fight their way inside the Platform, they could blast its

hull open, or demolish its controls or shatter its air pumps and its

gyros and turn its air tanks into sieves. Anything that could be damaged

would delay the take-off and so expose the Platform to further and

perhaps more successful attack.

There were more pistol shots. A group of men fought their way out of the

incoming screening rooms and raced for the center of the Shed. (Later,

it would be found they had slabs of explosive inside their garments, and

detonation caps to set them off.) Somewhere another door opened, and

Security men came out with flickering pistols, Major Holt leading them.

He had started out to fight off the truck-borne attack, but he was bound

to be too late. Joe's followers were trying to take care of that. The

scuttling men from the incoming rooms were Major Holt's first prey. They

were shot as they ran.

Joe stumbled and fell and he heard guns crackling. As he scrambled up he

pitched into a running figure that snarled as Joe hit him. And then he

was fighting for his life.

This was under the Platform and in the middle of confusion many times

confounded. Joe caught a wrist that held a gun. He knew his assailant

had a bomb slung over one shoulder and right now had one hand free for

combat. Joe instinctively tried to batter his enemy with his own pistol,

instead of pushing the muzzle against the man's body and pulling the

trigger. He struck a flailing blow, and his hand and the weapon struck a

metal brace. The blow cut his knuckles and paralyzed his fingers.

Despairingly he felt the pistol slipping from his grasp. Then his

assailant brought up his knee viciously, but it hit Joe's thigh instead

of his groin, and Joe flung his weight furiously forward and they

toppled to the ground together.

There was fighting all around him. The machine guns rasped again--there

was a burst of tracer-bullet fire. The panicked men by the exit tried to

surge out through the swinging doors. But the tracers marked a line they

must not cross. They checked. Once a gun flashed so close by Joe's eyes

that it blinded him. And once somebody fell over both himself and his

antagonist, who writhed like an eel possessed of desperate strength past

belief.

Joe could really know only his private part in the struggle down in the

murky tangle of the scaffold base. But there was fighting up on the

Platform itself. A savagely grinning Mohawk wrestled furiously with a

man on one of the rocket tubes. An incendiary device in the saboteur's

pocket ignited, and it flamed red-hot and he screamed as it burned its

way out of his garments. The Mohawk flung the man fiercely clear, to

crash horribly on the far-distant floor, and then kicked the incendiary

off. It fell after the man and hit and burst, and it was thermite which

surrounded itself with a column of acrid smoke from seared wood blocks.

There was fighting by the exit doors. There was an ululating uproar in

the incoming screening room, and a war whoop from the top of the

Platform. A saboteur tried to crawl into an air-lock entrance, and he

got his head and shoulders in, but a copper-skinned Indian held his

forehead still and chopped down with the side of his hand on that man's

neck. Underneath the Platform was panting chaos, with pistol shots and

hand-to-hand struggles everywhere. The force Joe had gathered fought

valiantly, but four invaders got to the foot of the wooden steps, where

there were two guards. Then there were only two saboteurs left to

scramble desperately up the steps over the dead guards' bodies and head

toward the Platform door, but the Chief appeared swinging a twelve-inch

Stillson. He let it go, precisely like a skillfully flung tomahawk, and

leaped down sixteen steps squarely onto the body of the other man. A gun

flashed, but then there was only squirming struggle on the floor.

Mike the midget, inside the Platform, found one bloodied, panting,

sobbing man who somehow had gotten inside. And Mike brought down a

spanner from a ladder step, and swarmed upon his half-conscious victim,

and hit him again, and then stayed on guard until somebody arrived who

was big enough to carry the saboteur away.

And all this while, Joe struggled with only one man. It was a horrible

struggle, because the man had a bomb and he might manage to set it off

or it might go off of itself. It was a ghastly struggle, because the man

had the strength and desperation of a maniac--and practiced the tactics.

Joe pounded the hand that held the gun upon the floor, and it hit

something and exploded smokily and fell clear. But that made things

worse. While struggling to kill Joe with the revolver, his antagonist

had had only five fingers with which to gouge out Joe's eyes or tear

away his ears or rend his flesh. But with no pistol he had ten, and he

fought like a wild beast. He even breathed like an animal. He began to

pant--thick, guttural pantings that had the quality of hellish hate. And

then there was a surging of bodies--Major Holt's reserve was arriving

very late in the center of the Shed--and then a struggling group

trampled all over the pair who squirmed and fought on the ground, and a

heavy boot jammed down Joe's head and he felt teeth sink in his throat.

They dug into his flesh, worrying and tearing....

Joe used his knee in a frenzy of revulsion--used his knee as the other

man had tried to use his in the first instant of battle. The man beneath

him screamed as an animal would scream, and Joe jerked his bleeding

throat free. In hysterical horror he pounded his antagonist's head on

the floor until the man went limp....

And then he heard a grim voice saying: "Quit it or you get your head

blown off! Quit it----" And Joe panted: "It's about time you guys got

here! This man came in on that truck. Watch out for that bomb he's got

slung on him...."

12

The incoming shift had a messy clean-up job to do. It was accomplished

only because security men abruptly took over the work of gang bosses,

and all ordinary labor on the Platform was put aside until normal

operations were again possible. Even that would not have been feasible

but for the walkie-talkies the security men wore. As the situation was

sorted out, it was explained to them, and they relayed the news for the

satisfaction of the curiosity of those who worked under them. No

work--no explanation. It produced immediate and satisfactory

co-operation all around.

There had been four separate and independent attempts to wreck the

Platform at the same time. One was, of course, the plan of those

sympathetic characters who had volunteered to help Mike and his gang win

the status of spacemen by firing the Platform's rockets. There were not

many of them, and they had lost heavily. They'd had thermite bombs to

destroy the Platform's vitals. Ultimately the survivors talked freely,

if morosely, and that was that.

There had been a particularly ungifted attempt to cause panic in the

incoming shift in the rooms where its members were screened before

admission to work. Somebody had tried to establish complete confusion

there by firing revolver shots in the crowd, expecting the workers to

break through to the floor and assigned gentlemen with slabs of

explosive to get to the Platform with them. The gentlemen with the

explosives had run into Major Holt's security reserve, and they got

nowhere. The creators of panic with revolver shots were finally rescued

from their shift-mates and more or less scraped up from the

screening-room floor--they were in very bad shape--and carted off to be

patched up for questioning. The members of this group had been

impractical idealists, and besides, some of them had lost their nerve,

as was evidenced by the discovery of abandoned explosives and detonators

in the locker room and men's room of the Shed.

The most dangerous attempt was, of course, that perfectly planned and

co-ordinated assault which had been merely carried out at its original

time, without either being hastened or delayed by Mike's activities.

That plan had been beautifully contrived, and it would certainly have

been successful but for the machine-gun bullets from the gallery and the

fight Joe's followers put up underneath the Platform.

The exact instant when the whole Shed would be most nearly empty had

been fixed upon, and three separate units had worked in perfect timing.

There'd been the man in the stalled truck. He'd delayed his exit from

the Shed to the precise fraction of a second to get the doors open at

the perfect instant. The explosive-laden trucks had raced in at the

exact second when they were most certain to get underneath the Platform

and detonate their cargoes. There'd been a perfect diversion planned for

that, too. Smoke bombs and explosions in the outgoing screening rooms

had created real panic, and but for Joe's order for his group's

walkie-talkies to be turned off would have drawn every security man on

duty to that spot.

Mike's trick, then, had brought some saboteurs into the open, but had

merely happened to coincide with the most dangerous and well-organized

coup of all. However, it was due to his trick that the Platform was not

now a wreck.

There was also another break that was sheer coincidence. It was a

discovery that could not possibly have turned up save in a situation of

pure chaos artificially induced. Joe had had to react in a personal and

vengeful way to the manner in which his especial antagonist had fought

him. One expects a man to fight fair by instinct, and to turn to

fouls--if he does--in desperation only. But Joe's personal opponent

hadn't tried a single fair trick. It was as if he'd never heard of a

fist blow, but only of murder and mayhem. Joe felt an individual enmity

toward him.

Joe didn't consider himself the most urgent of the injured, when doctors

and nurses took up the work of patching, but Sally was there to help,

and she went deathly pale when she saw his bloodstained throat. She

dragged him quickly to a doctor. And the doctor looked at Joe and

dropped everything else.

But it wasn't too serious. The antiseptics hurt, and the stitching was

unpleasant, but Joe was more worried by the knowledge that Sally was

standing there and suffering for him. When he got up from the emergency

operating table, the doctor nodded grimly to him.

"That was close!" said the doctor. "Whoever chewed you was working for

your jugular vein, and he was halfway through the wall when he stopped.

A fraction of an inch more, and he'd have had you!"

"Thanks," said Joe. His neck felt clumsy with bandages, and when he

tried to turn his head the stitches hurt.

Sally's hand trembled in his when she led him away.

"I didn't think I'd ever dislike anybody so much," said Joe angrily, "as

I did that man while he was chewing my throat. We were trying to kill

each other, of course, but--confound it, people don't bite!"

"Did you--kill him?" asked Sally in a shaky voice. "Not that I'll mind!

I would have hated the thought ordinarily, but----"

Joe halted. There was a row of stretchers--not too long, at that--in the

emergency-hospital space. He looked down at the unconscious man who'd

fought him.

"There he is!" he said irritably. "I banged him pretty hard. I don't

like to hate anybody, but the way he fought----"

Sally's teeth chattered suddenly. She called to one of the security men

standing guard by the stretchers.

"I--think my--father is going to want to talk to him," she said

unsteadily. "Don't--let him be taken away to the hospital until Dad

knows, please."

She started away, her face dead-white and her hand stone-cold.

"What's the matter?" demanded Joe.

"S-sabotage," said Sally in an indescribable tone that had a suggestion

of heartbreak.

She went into her father's office alone. She came out again with him,

and her father looked completely stricken. Miss Ross, his secretary, was

with him, too. Her face was like a mask of marble. She had always been a

plain woman, a gloomy one, a morbid one. But at the new and horrible

look on her face Joe turned his eyes away.

Then Sally was crying beside him, and he put his arm clumsily around her

and let her sob on his shoulder, completely puzzled.

He didn't find out until later what the trouble was. The man who'd tried

so earnestly to kill him was Miss Ross's fiance. She had met this man

during a vacation, as a government secretary, and he was a refugee with

an exotic charm that would have fascinated a much more personable and

beautiful woman than Miss Ross. They had a whirlwind romance. He

confided to her his terror of emissaries from his native country who

might kill him. And of course she was more fascinated still. When he

asked her to marry him she accepted his proposal. Then, just two weeks

before her assignment to the Space Platform project, he vanished. Miss

Ross was desperate and lovesick.

One day her telephone rang and his anguished voice told her he'd been

abducted, and if she told the police he would be tortured to death. He

begged her not to do anything to cause him more torment than was already

his.

She'd been trying to keep him alive ever since. Once, when she couldn't

bring herself to carry out an order she'd been given--with threats of

torment to him if she failed--she'd received a human finger in the mail,

and a scrawled and blood-stained note which cried out of unspeakable

torment and begged her not to doom him to more.

So Miss Ross, who was Major Holt's secretary and one of his most trusted

assistants, had been giving information to one group of saboteurs all

the while. She was the most dangerous security leak in the whole

Platform project.

But her fiance wasn't a captive. He was the head of that group of

saboteurs. He'd made love to her and proposed to her merely to prepare

her to supply the information he wanted. He needed only to write a

sufficiently agonized note, or gasp tormented pleas on a telephone, to

get what he wanted.

Incidentally, he still had all his fingers when Joe knocked him cold.

Sally had recognized him as the subject of a snapshot she'd once seen

Miss Ross crying over. Miss Ross had hidden it hastily and told her it

was someone she had once loved, now dead. And this inadvertent

disclosure that Miss Ross was the security leak the Major had never had

a clue to could only have come about through such confusion as Mike had

instigated and Haney and the Chief and Joe had organized. But Joe

learned those facts only later.

At the moment, there was still the Platform to be gotten aloft. And

there was plenty of work to do. There were two small rips in the

plating, caused by fragments of the exploded truck. There were some

bullet holes. The Platform could resist small meteorites at forty-five

miles a second, but a high-velocity small-arm projectile could puncture

it. Those scars of battle had to be welded shut. The rest of the

scaffolding had to come down and the rest of the rocket tubes had to be

affixed. And there was cleaning up to be done.

These things occupied the shift that came on at the time of the multiple

sabotage assaults. At first the work was ragged. But the policy of

turning the Security men into news broadcasters worked well. After all,

the Platform was a construction job and the men who worked on it were

not softies. Most of them had seen men killed before. Before the shift

was half over, a definite work rhythm was evident. Men had begun to take

an even greater pride in the thing they had built, because it had been

assailed and not destroyed. And the job was almost over.

Sally went back to her father's quarters, to try to sleep. Joe stayed in

the Shed. His throat was painful enough so that he didn't want to go to

bed until he was genuinely tired, and he was thoroughly wrought up.

Mike the midget had gone peacefully to sleep again, curled up in a

corner of the outgoing screening room. His fellow midgets talked

satisfiedly among themselves. Presently, to show their superiority to

mere pitched battles, two of them brought out a miniature pack of cards

and started a card game while they waited for a bus to take them back to

Bootstrap.

The Chief's Indian associates loafed comfortably while waiting for the

same busses. Later they would put in for overtime--and get it. Haney

mourned that he had been remote from the scene of action, and was merely

responsible for the presence and placing and firing of the machine guns

that had certainly kept the Platform from being blown up from below.

It seemed that nothing else would happen to bother anybody. But there

was one thing more.

That thing happened just two hours before it was time for the shift to

change once again, and when normal work was back in progress in the

Shed. Everything seemed fully organized and serene. Everything in the

Shed had settled down, and nothing had happened outside.

There was ample exterior protection, of course, but the outside-guard

system hadn't had anything to do for a very long time. Men at radar

screens were bored and sleepy from sheer inactivity and silence. Pilots

in jet planes two miles and five miles and eight miles high had long

since grown weary of the splendid view below them. After all, one can

get very used to late, slanting moonlight on cloud masses far

underneath, and bright and hostile-seeming stars overhead.

So the thing was well timed.

A Canadian station noticed the pip on its radar screen first. The radar

observer was puzzled by it. It could have been a meteor, and the

Canadian observer at first thought it was. But it wasn't going quite

fast enough, and it lasted too long. It was traveling six hundred

seventy-two miles an hour, and it was headed due south at sixty thousand

feet. The speed could have been within reason--provided it didn't stay

constant. But it did. There was something traveling south at eleven

miles a minute or better. A mile in five-plus seconds. It didn't slow.

It didn't drop.

The Canadian radarman debated painfully. He stopped his companion from

the reading of a magazine article about chinchilla breeding in the home.

He showed him the pip, still headed south and almost at the limit of

this radar instrument's range. They discussed the thing dubiously. They

decided to report it.

They had a little trouble getting the call through. The night

long-distance operators were sleepy. Because of the difficulty of making

the call, the radarmen became obstinate and insisted on putting it

through. They reported to Ottawa that some object flying at sixty

thousand feet and six hundred seventy-two miles an hour was crossing

Canada headed for the United States.

There was a further time loss. Somebody in authority had to be awakened,

and somebody had to decide that a further report was justified. Then the

trick had to be accomplished, and a sleepy man in a bathrobe and

slippers listened and said sleepily, "Oh, of course you'll tell the

Americans. It's only neighborly!" and padded back to his bed to go to

sleep again. Then he waked up suddenly and began to sweat. He'd realized

that this might be the beginning of atomic war. So he set phone bells to

jangling furiously all over Canada, and jet planes began to boom in the

darkness.

But there was only one object in the sky. Over the Dakotas it went

higher. It went to seventy thousand feet, and then eighty. How this was

managed is not completely known, because there are still some details of

that flight that have never been completely explained. But certainly

jatos flared briefly at some point, and the object reached ninety

thousand feet where a jet motor would certainly be useless. And then,

almost certainly, rockets flared once more and well south of the Dakotas

it started down in a trajectory like that of an artillery shell, but

with considerably higher speed than most artillery shells achieve.

It was at about this time that the siren in the Shed began its choppy,

hiccoughing series of warm-up notes. The news from Canada arrived, as a

matter of fact, some thirty seconds after the outer-perimeter radar

screen around the Platform gave its warning. Then there was no

hesitation or delay at all. Men were already tumbling out of bed at

three airfields, buckling helmets and hoping their oxygen tanks would

function properly. Then the radars atop the Shed itself picked up the

moving speck. And small blue-white flames began to rise from the ground

and go streaking away in the darkness in astonishing numbers.

The covers of the guns at the top of the Shed slid aside. Miles away,

jet planes shot skyward, and newly wakened pilots looked at their

night-fighting instruments and swore unbelievingly at the speed they

were told the plunging object was making. The jet pilots gave their

motors everything they could take, but it didn't look good.

The planes of the jet umbrella over the Shed stopped cruising and

sprinted. And they were the only ones likely to get in front of the

object in time.

Inside the Shed, the siren howled dismally and all the Security men were

snapping: "Radar alarm! All out! Radar alarm! All out!"

And men were moving fast, too. Some came down from the Platform on

hoists, dropping with reckless speed to the floor level. Some didn't

wait for a turn at that. They slid down one upright, swung around the

crosspiece on the level below, and slid down another vertical pipe. For

a minute or more it looked as if the scaffolds oozed black droplets

which slid down its pipes. But the drops were men. The floor became

speckled and spotted with dots running for its exits.

The siren ceased its wailing and its noise went down and down in pitch

until it was a baritone moan that dropped to bass and ceased. Then there

was no sound but the men moving to get out of the Shed. There were

trucks, too. Those that had been loading with dismantled scaffolding

roared for the doors to get out and away. Some men jumped on board as

they passed. The exit doors swung up to let them go.

But it was very quiet in the Shed, at that. There was no noise but a few

fleeing trucks, and the murmur which was the voices of the Security men

hurrying the work crew out. There was less to hear than went on

ordinarily. And it was a long distance across the floor of the Shed.

Joe stood with his fists clenched absurdly. This could only be an air

attack. An air attack could only mean an atom-bomb attack. And if there

was an atom bomb dropped on the Shed, there'd be no use getting outside.

It wouldn't be merely a fission bomb. It would be a hell bomb--a bomb

which used the kind of bomb that shattered Hiroshima only as a primer

for the real explosive. Nobody could hope to get beyond the radius of

its destruction before it hit!

Joe heard himself raging. He'd thought of Sally. She'd be in the range

of annihilation, too. And Joe knew such fury and hatred--because of

Sally--that he forgot everything else.

He didn't run. He couldn't escape. He couldn't fight back. But because

he hated, he had to do something to defy.

He found himself moving toward the Platform, his jaws clenched. It was

pure, blind, instinctive defiance.

He was not the only one to have that reaction. Men running toward the

sidewall exits began to get out of breath from their running. They

slowed. Presently they stopped. They scowled and raged, like Joe. Some

of them looked with burning eyes up at the roof of the Shed, though

their thoughts went on beyond it. The security guards repeated, "Radar

alarm! All out! Radar alarm! All out!"
