Steel turned to a man beside him. "What was the cargo?"

"That--that's what's so awful," the fellow said. "It was carrying a

load of Venusian tungsoid. And there ain't but two things you can make

with tungsoid--electrotubes or _suffo-gas_!"

Suffo-gas! A deadly vapor, its production had been banned on Earth ever

since mankind moved underground. One whiff of suffo-gas in New York's

ventilation pipes.... Steel turned back through the crowd.

He didn't take the belt to the hotel. He walked, big hands deep in his

pockets, thinking, thinking things he hardly dared think of.

That ship had been pirated close by. Its route in from Venus was from

the south-east. That cargo of tungsoid had been pirated over the

Jersey Ruins. He was on the right track and it was a hurry-up job.

There was little reason to believe The Bear had gotten interested in

electrotubes....

* * * * *

Next morning when the first yellow rays of the sun's dying ember

slanted across the ice, Steel's ski plane circled up from the Terminal

and headed south-east.

Crossing the sub-zero ice crevices on foot would have taken months

but it was just a short hop by plane. It was a hop, however, that few

planes took. Freight and liner traffic from the Terminal immediately

headed for the stratosphere. Near the surface, the glacier's fangs

probed every cloud and blizzards of liquid air roamed the uncharted

chasms. Only an occasional prospector or hunter attempted low-altitude

flying here and often these never returned.

This morning, however, Steel was lucky. The weather was clear and

ceiling unusually high, the peaks rearing from the shadow-filled

valleys like glittering icicles in the pale yellow light. When he

checked his instruments by the chart and headed the plane down over the

ice field that choked the Jersey Ruins, he grinned silently behind the

control lever. Now, if the blizzard would only hold off for an hour or

so....

The crumbling ruins of ancient buildings jutted up from the snow,

monuments of a long-departed civilization. Although never actually

explored, the Ruins were thought to extend for miles south of the

comet crater. More was known about the crater itself since it was only

a few centuries old. Its gigantic explosion had knifed a deep valley

in the ice mountains that was still relatively warm. Lichen grew on

the snow here, bats hung in the caves, and ice-bears had a shorter

hibernation. And _The_ Bear? Any crevice, any ruined building here

might be his lair.

Scanning the drifts below through his windows, Steel looked for

tracks, melting snow or rocket stains. As he looked, he kept an eye on

his auto-sextant. As it clicked off the changing coordinates of his

location, he marked his position on the chart. Vanish he might like

those other five cops who'd gone after The Bear, Steel thought, but not

without a trace--not as long as the little microphone in his helmet was

ready for an instant S.O.S. He'd tested it at the Terminal; Stahl's man

was on the job.

On a little plateau below, he saw a herd of bluish white snow-deer.

They looked up and then stampeded in all directions as he passed over.

Odd he hadn't seen any bears yet.

He was banking low over the half-buried top of a building, squinting

down at the white drifts, when he saw the ball.

"Now how the hell did that happen...."

He circled lower. It was a ball of solid ice. He could see all the way

through it. It was about six feet in diameter, smooth as glass. It was

perfectly round, like a huge green bubble. It lay there on the snow,

sparkling in the dull light. "Funny ice formation--"

Then the ball _moved_.

Watching, Steel almost rammed a building. He pulled up, staring at

the thing. The ball rose slowly, ten feet above the snow. Suspended

by nothing. Then it drifted slowly over the wastes, aimlessly, like a

bubble in the breeze.

Steel followed it, amazed. A strong air current? But it wasn't

affecting the plane. Besides, that chunk of ice probably weighed half a

ton!

The thing finally came to rest against an ice crag near one of the

wrecked buildings. Steel went in close and hovered, examining it with

bewildered eyes. And it was just a ball of ice. That's all it _was_.

Well, lots of queer things happened on the glacier.... Shaking his

head, he started to zoom away.

Then it happened.

More of the ice balls! Hundreds of them! Curving down upon him from

above!

Colorless, unseen until they were upon him, they blocked the plane on

every side.

"What in the--!" Steel banked, twisted the plane into every contortion.

But at every turn the glistening spheres stood before him, closing in

like a net, relentlessly forcing him down.

Fifty feet above the snow, he realized he'd have to ram them. The plane

was strong--maybe he could crash through.

Then, as if anticipating this very thought, the spheres moved in

suddenly against the plane, pressed upon it from above, forced it down.

It was pressed quickly down to the snow.

As it settled into the snow level with the cabin windows, the spheres

slowly melted together to form a rough-hewn roof and walls. The plane

was enclosed completely.

Steel's heart hammered. His breath fogged his helmet. He stared at the

encircling wall, jerked the control lever helplessly. It was only then

he remembered his microphone.

"Six-foot balls of ice!" he cried hoarsely. "Some kind of remote

control! X-26.9-18.7!" He started giving the coordinates of his

location.

"_That's hardly worth while now...._"

Steel shivered even in the electrosuit's warmth. Slowly, he turned

around.

The walls and roof that imprisoned him joined, behind him, the side

of one of the ruined buildings, a crumbling structure of weathered

concrete. The ruin had a door. In the door, an oxygen helmet topping a

snow-white electrosuit, stood a tall thin man. One gloved hand rested

lightly upon the butt of a volt pistol holstered at his hip.

"_Our little Trojan Horse--those balls of ice_," the man continued,

"_have several interesting properties. They're also a very effective

barrier against radio transmission._" His voice was coming into the

plane on the same radio frequency Steel had been trying to send on.

Behind his helmet, the man's face was lean, thin-lipped, deeply

tanned--a tan that wasn't of Earth. That tan had come through a

space ship's viewplate, close in the heat of some foreign sun. He

strode over to the plane and took out his pistol to rap impatiently on

the cabin window.

"_Get out of there! That hunting license on your ship doesn't fool me.

A few minutes ago you passed over a herd of snow-deer without firing a

shot. The Bear will be mighty interested in why you're up here snooping

around...._"

* * * * *

The Bear--the word hit Steel like an electric shock. He'd thought he

was on the right track, he'd hoped, but now that it was proved it was

something to think about. He'd found The Bear's hideout and what could

he do about it?

He didn't move at first. He sat there looking at the man through the

window, his mind running hot trying to figure out what to do. In the

middle of the glacier, a six-foot-thick wall in front of him, the man

with the gun outside. _And_ his radio useless--his ace card trumped

with the game just started. It looked like that insurance policy hadn't

been a bad idea....

The fellow banged on the plane with his pistol again. "_Come on! Open

up!_"

Steel opened up. At a wave of the pistol, he stepped out to the frozen

snow. At another wave, he raised his hands. The man stepped around

him, jabbed the gun in his spine and went over him expertly. He found

Steel's pistol and dropped it in the snow. "_Now start walking ahead

of me. And no foolishness._" The pistol shoved Steel ahead through the

ruin's door.

Inside it was just like ten million other surface ruins. You walked

into what had been about the thirtieth floor above the street and found

only drifted snow, shattered walls, a bleached skeleton perhaps. Now,

however, Steel had time for only a glance at the familiar scene when

the pistol moved him on through another door, then another, and this

one, he saw, only faked its weathered appearance. As he went through,

a metal panel slid silently shut behind them and he had his first

look at the tremendous organization he'd been fool enough to tackle

single-handed.

A bright warming glow drifted down from the luminous ceiling. Vent

slits in the floor whispered softly, oxygen pouring in. At the other

end of the room, a split traveling walk slid noiselessly up and down

a shaft past hundreds of offices, workshops, barracks. The place was

as big as the Terminal, as lavishly furnished as Stahl's Vita-Heat

Building. This place explained why The Bear had stolen as much

equipment as money.

He was given little time to marvel here however.

"_Take off your helmet_," the radioed voice behind him ordered. Steel

took it off. When he turned, facing the man and the gun, the man had

removed his own helmet. He was smiling, a thin tight-lipped smile with

no humor in his eyes. "You seem surprised," he said. "You really didn't

expect a bear's den, did you?"

"This is your show," Steel said quietly. "What comes next?" The man

held his helmet in one hand, his pistol in the other--both hands full.

Steel thought of his own helmet, a mighty handy weapon. If he got a

chance--Then suddenly he noticed something else, something that gave

him a chance cops dreamed about. The guy's pistol--the safety was _on_!

"Okay," the man said, "if this deer hunting trip of yours turns out to

be faked, you'll soon learn what's next." A quick motion of the pistol

ordered Steel around on the belt that led down the shaft.

Steel went. As he went, he shot quick glances into the rooms they

passed, waiting for the right moment to whirl around and knock that

pistol away.

The rooms they passed were filled with workers. There were drafting

stalls where scores of men--and women--bent over blueprint tables

and charts. There were plastic workshops where people operated

compression molds and lathes. Where did The Bear get all these

workers! They all couldn't have come from the upper levels! There were

glittering laboratories where white-aproned technicians huddled around

distillation vats and rows of test tubes. Steel thought of that stolen

cargo of tungsoid. Suffo-gas...?

A few yards ahead, on the left, he saw they were approaching an empty

room. On the right, a deserted tunnel branched off into whatever

labyrinth the place possessed. Okay, this was as good as anywhere else!

Wherever he was being taken, they'd be there shortly. Then it might be

too late.

Steel crouched slightly, ready to whirl on the fellow behind him.
