Two men had died before Syme Rector's guns

to give him the key to the ancient city of

Kal-Jmar--a city of untold wealth, and of

robots that made desires instant commands.

The tall man loitered a moment before a garish window display, his eyes

impassive in his space-burned face, as the Lillis patrolman passed.

Then he turned, burying his long chin in the folds of his sand cape,

and took up the pursuit of the dark figure ahead once more.

Above, the city's multicolored lights were reflected from the

translucent Dome--a distant, subtly distorted Lillis, through which the

stars shone dimly.

Getting through that dome had been his first urgent problem, but now he

had another, and a more pressing one. It had been simple enough to pass

himself off as an itinerant prospector and gain entrance to the city,

after his ship had crashed in the Mare Cimmerium. But the rest would

not be so simple. He had to acquire a spaceman's identity card, and he

had to do it fast. It was only a matter of time until the Triplanet

Patrol gave up the misleading trail he had made into the hill country,

and concluded that he must have reached Lillis. After that, his only

safety lay in shipping out on a freighter as soon as possible. He had

to get off Mars, because his trail was warm, and the Patrol thorough.

They knew, of course, that he was an outlaw--the very fact of the

crashed, illegally-armed ship would have told them that. But they

didn't know that he was Syme Rector, the most-wanted and most-feared

raider in the System. In that was his only advantage.

He walked a little faster, as his quarry turned up a side street and

then boarded a moving ramp to an upper level. He watched until the

short, wide-shouldered figure in spaceman's harness disappeared over

the top of the ramp, and then followed.

The man was waiting for him at the mouth of the ascending tunnel.

Syme looked at him casually, without a flicker of expression, and

started to walk on, but the other stepped into his path. He was quite

young, Syme saw, with a fighter's shoulders under the white leather,

and a hard, determined thrust to his firm jaw.

"All right," the boy said quietly. "What is it?"

"I don't understand," Syme said.

"The game, the angle. You've been following me. Do you want trouble?"

"Why, no," Syme told him bewilderedly. "I haven't been following you.

I--"

The boy knuckled his chin reflectively. "You could be lying," he said

finally. "But maybe I've made a mistake." Then--"Okay, citizen, you can

clear--but don't let me catch you on my tail again."

Syme murmured something and turned away, feeling the spaceman's eyes

on the small of his back until he turned the corner. At the next

street he took a ramp up, crossed over and came down on the other side

a block away. He waited until he saw the boy's broad figure pass the

intersection, and then followed again more cautiously.

It was risky, but there was no other way. The signatures, the data,

even the photograph on the card could be forged once Syme got his hands

on it, but the identity card itself--that oblong of dark diamondite,

glowing with the tiny fires of radioactivity--that could not be

imitated, and the only way to get it was to kill.

Up ahead was the Founders' Tower, the tallest building in Lillis. The

boy strode into the entrance lobby, bought a ticket for the observation

platform, and took the elevator. As soon as his car was out of sight in

the transparent tube, Syme followed. He put a half-credit slug into the

machine, took the punctured slip of plastic that came out. The ticket

went into a scanning slot in the wall of the car, and the elevator

whisked him up.

* * * * *

The tower was high, more than a hundred meters above the highest level

of the city, and the curved dome that kept air in Lillis was close

overhead. Syme looked up, after his first appraising glance about the

platform, and saw the bright-blue pinpoint of Earth. The sight stirred

a touch of nostalgia in him, as it always did, but he put it aside.

The boy was hunched over the circular balustrade a little distance

away. Except for him, the platform was empty. Syme loosened his slim,

deadly energy pistol in its holster and padded catlike toward the

silent figure.

It was over in a minute. The boy whirled as he came up, warned by

some slight sound, or by the breath of Syme's passage in the still

air. He opened his mouth to shout, and brought up his arm in a swift,

instinctive gesture. But the blow never landed. Syme's pistol spat its

silent white pencil of flame, and the boy crumpled to the floor with a

minute, charred hole in the white leather over his chest.

Syme stooped over him swiftly, found a thick wallet and thrust it into

his pocket without a second glance. Then he raised the body in his arms

and thrust it over the parapet.

It fell, and in the same instant Syme felt a violent tug at his wrist.

Before he could move to stop himself, he was over the edge. Too late,

he realized what had happened--one of the hooks on the dead spaceman's

harness had caught the heavy wristband of his chronometer. He was

falling, linked to the body of his victim!

Hardly knowing what he did, he lashed out wildly with his other arm,

felt his fingertips catch and bite into the edge of the balustrade. His

body hit the wall of the tower with a thump, and, a second later, the

corpse below him hit the wall. Then they both hung there, swaying a

little and Syme's fingers slipped a little with each motion.

Gritting his teeth, he brought the magnificent muscles of his arm into

play, raising the forearm against the dead weight of the dangling body.

Fraction by slow fraction of an inch, it came up. Syme could feel the

sweat pouring from his brow, running saltily into his eyes. His arms

felt as if they were being torn from their sockets. Then the hook

slipped free, and the tearing, unbearable weight vanished.

The reaction swung Syme against the building again, and he almost

lost his slippery hold on the balustrade. After a moment he heard the

spaceman's body strike with a squashy thud, somewhere below.

He swung up his other arm, got a better grip on the balustrade. He

tried cautiously to get a leg up, but the motion loosened his hold on

the smooth surface again. He relaxed, thinking furiously. He could hold

on for another minute at most; then it was the final blast-off.

He heard running footsteps, and then a pale face peered over the ledge

at him. He realized suddenly that the whole incident could have taken

only a few seconds. He croaked, "Get me up."

Wordlessly, the man clasped thin fingers around his wrist. The other

pulled, with much puffing and panting, and with his help Syme managed

to get a leg over the edge and hoist his trembling body to safety.

"Are you all right?"

* * * * *

Syme looked at the man, nursing the tortured muscles of his arms. His

rescuer was tall and thin, of indeterminate age. He had light, sandy

hair, a sharp nose, and--oddly conflicting--pale, serious eyes and a

humorous wide mouth. He was still panting.

"I'm not hurt," Syme said. He grinned, his white teeth flashing in his

dark, lean face. "Thanks for giving me a hand."

"You scared hell out of me," said the man. "I heard a thud. I

thought--you'd gone over." He looked at Syme questioningly.

"That was my bag," the outlaw said quickly. "It slipped out of my hand,

and I overbalanced myself when I grabbed for it."

The man sighed. "I need a drink. _You_ need a drink. Come on." He

picked up a small black suitcase from the floor and started for the

elevator, then stopped. "Oh--your bag. Shouldn't we do something about

that?"

"Never mind," said Syme, taking his arm. "The shock must have busted it

wide open. My laundry is probably all over Lillis by now."

They got off at the amusement level, three tiers down, and found a

cafe around the corner. Syme wasn't worried about the man he had just

killed. He had heard no second thud, so the body must have stayed on

the first outcropping of the tower it struck. It probably wouldn't be

found until morning.

And he had the wallet. When he paid for the first round of _culcha_, he

took it out and stole a glance at the identification card inside. There

it was--his ticket to freedom. He began feeling expansive, and even

friendly toward the slender, mouse-like man across the table. It was

the _culcha_, of course. He knew it, and didn't care. In the morning

he'd find a freighter berth--in as big a spaceport as Lillis, there

were always jobs open. Meanwhile, he might as well enjoy himself, and

it was safer to be seen with a companion than to be alone.

He listened lazily to what the other was saying, leaning his tall,

graceful body back into the softly-cushioned seat.

"Lissen," said Harold Tate. He leaned forward on one elbow, slipped,

caught himself, and looked at the elbow reproachfully. "Lissen," he

said again, "I trust you, Jones. You're obvi-obviously an adventurer,

but you have an honest face. I can't see it very well at the moment,

but I hic!--pardon--seem to recall it as an honest face. I'm going to

tell you something, because I need your help!--help." He paused. "I

need a guide. D'you know this part of Mars well?"

"Sure," said Syme absently. Out in the center of the floor, an AG

plate had been turned on. Five Venusian girls were diving and twisting

in its influence, propelling themselves by the motion of their

delicately-webbed feet and trailing long gauzy streamers of synthesilk

after them. Syme watched them through narrowed lids, feeling the glow

of _culcha_ inside him.

"I wanta go to Kal-Jmar," said Tate.

Syme snapped to attention, every nerve tingling. An indefinable sense,

a hunch that had served him well before, told him that something big

was coming--something that promised adventure and loot for Syme Rector.

"Why?" he asked softly. "Why to Kal-Jmar?"

Harold Tate told him, and later, when Syme had taken him to his rooms,

he showed him what was in his little black suitcase. Syme had been

right; it was big.

* * * * *

Kal-Jmar was the riddle of the Solar System. It was the only remaining

city of the ancient Martian race--the race that, legends said, had

risen to greater heights than any other Solar culture. The machines,

the artifacts, the records of the Martians were all there, perfectly

preserved inside the city's bubble-like dome, after God knew how many

thousands of years. But they couldn't be reached.

For Kal-Jmar's dome was not the thing of steelite that protected

Lillis: it was a tenuous, globular field of force that defied analysis

as it defied explosives and diamond drills. The field extended both

above and below the ground, and tunneling was of no avail. No one knew

what had happened to the Martians, whether they were the ancestors of

the present decadent Martian race, or a different species. No one knew

anything about them or about Kal-Jmar.

In the early days, when the conquest of Mars was just beginning, Earth

scientists had been wild to get into the city. They had observed it

from every angle, taken photographs of its architecture and the robots

that still patrolled its fantastically winding streets, and then they

had tried everything they knew to pierce the wall.

Later, however, when every unsuccessful attempt had precipitated a

bloody uprising of the present-day Martians--resulting in a rapid

dwindling of the number of Martians--the Mars Protectorate had stepped

in and forbidden any further experiments; forbidden, in fact, any

Earthman to go near the place.

Thus matter had stood for over a hundred years, until Harold Tate.

Tate, a physicist, had stumbled on a field that seemed to be identical

in properties to the Kal-Jmar dome; and what is more, he had found a

force that would break it down.

And so he had made his first trip to Mars, and within twenty-four

hours, by the blindest of chances, blurted out his secret to Syme

Rector, the scourge of the spaceways, the man with a thousand credits

on his sleek, tigerish head.

Syme's smile was not tigerish now; it was carefully, studiedly mild.

For Tate was no longer drunk, and it was important that it should not

occur to him that he had been indiscreet.

"This is native territory we're coming to, Harold," he said. "Better

strap on your gun."

"Why. Are they really dangerous?"

"They're unpredictable," Syme told him. "They're built differently, and

they think differently. They breathe like us, down in their caverns

where there's air, but they also eat sand, and get their oxygen that

way."

"Yes, I've heard about that," Tate said. "Iron oxide--very interesting

metabolism." He got his energy pistol out of the compartment and

strapped it on absently.

Syme turned the little sand car up a gentle rise towards the tortuous

hill country in the distance. "Not only that," he continued. "They

eat the damndest stuff. Lichens and fungi and tumble-grass off the

deserts--all full of deadly poisons, from arsenic up the line to

xopite. They seem intelligent enough--in their own way--but they never

come near our cities and they either can't or won't learn Terrestrial.

When the first colonists came here, they had to learn _their_ crazy

language. Every word of it can mean any one of a dozen different

things, depending on the inflection you give it. I can speak it some,

but not much. Nobody can. We don't think the same."

"So you think they might attack us?" Tate asked again, nervously.

"They _might_ do anything," Syme said curtly. "Don't worry about it."

The hills were much closer than they had seemed, because of Mars'

deceptively low horizon. In half an hour they were in the midst of a

wilderness of fantastically eroded dunes and channels, laboring on

sliding treads up the sides of steep hills only to slither down again

on the other side.

* * * * *

Syme stopped the car abruptly as a deep, winding channel appeared

across their path. "Gully," he announced. "Shall we cross it, or follow

it?"

Tate peered through the steelite nose of the car. "Follow, I guess,"

he offered. "It seems to go more or less where we're going, and if we

cross it we'll only come to a couple dozen more."

Syme nodded and moved the sand car up to the edge of the gully. Then he

pressed a stud on the control board; a metal arm extruded from the tail

of the car and a heavy spike slowly unscrewed from it, driving deep

into the sand. A light on the board flashed, indicating that the spike

was in and would bear the car's weight, and Syme started the car over

the edge.

As the little car nosed down into the gully, the metal arm left behind

revealed itself to be attached to a length of thick, very strong wire

cable, with a control cord inside. They inched down the almost vertical

incline, unreeling the cable behind them, and starting minor landslides

as they descended.

Finally they touched bottom. Syme pressed another stud, and above, the

metal spike that had supported them screwed itself out of the ground

again and the cable reeled in.

Tate had been watching with interest. "Very ingenious," he said. "But

how do we get up again?"

"Most of these gullies peter out gradually," said Syme, "but if we want

or have to climb out where it's deep, we have a little harpoon gun that

shoots the anchor up on top."

"Good. I shouldn't like to stay down here for the rest of my

natural life. Depressing view." He looked up at the narrow strip of

almost-black sky visible from the floor of the gully, and shook his

head.

Neither Syme nor Tate ever had a chance to test the efficiency of their

harpoon gun. They had traveled no more than five hundred meters, and

the gully was as deep as ever, when Tate, looking up, saw a deeper

blackness blot out part of the black sky directly overhead. He shouted,

"Look out!" and grabbed for the nearest steering lever.

The car wheeled around in a half circle and ran into the wall of the

gully. Syme was saying, "What--?" when there was a thunderous crash

that shook the sturdy walls of the car, as a huge boulder smashed into

the ground immediately to their left.

When the smoky red dust had cleared away, they saw that the left tread

of the sand car was crushed beyond all recognition.

Syme was cursing slowly and steadily with a deep, seething anger. Tate

said, "I guess we walk from here on." Then he looked up again and

caught a glimpse of the horde of beasts that were rushing up the gully

toward them.

"My God!" he said. "What are those?"
