Chapter I

The Menace from Space

THE big liner Pallas throbbed through space on its regular run from Venus to Earth. In the brightly lighted saloons of the big shop, throngs of men and women drank, laughed, talked or danced to the haunting music of the native Venusian orchestra.

Up in the televisor room, “Sparks” yawned over his instruments. Then the youthful Earthman operator looked up quickly as the stocky first mate of the liner entered the room.

“Call Earth Spaceport Four and tell them we’ll dock at ten sharp tomorrow,” the mate ordered.

Sparks punched his switches, pressed the call-button. The televisor screen broke into light. In it appeared the chief dispatcher, on duty at Earth Spaceport 4.

The dispatcher heard the report and then nodded.

“Okay, Pallas. We’ll have Dock Fifteen ready for—”

Then it happened!

The televisor went blank as an untuned wave of incredible power crowded onto it. Then the image of a man appeared in it.

“What the devil—” Sparks gasped. The man in the screen was an extraordinary-looking individual. He seemed an Earthman, yet his tall, gaunt, black-clothed figure, his enormous bulging forehead and skull, and his hypnotically burning black eyes, gave to his aspect some indefinable but startling aura of the superman.

“Doctor Zarro calling the Solar System peoples,” he rasped in a deep, harsh voice. “People of the nine worlds, I bring you warning of a dreadful peril—a peril which your bungling, stupid scientists have not yet even discovered.

“A huge dark star is rushing upon our Solar System from the boundless abyss of outer space! This colossal dead sun is coming from the direction of the constellation Sagittarius—its exact position is Right Ascension, seventeen hours, forty-one minutes, Declination, minus twenty-seven degrees, forty-eight minutes. It is coming straight toward us and will reach our System in several weeks, at its present speed. This on-coming monster will wreck our System—unless it is turned aside.”

DOCTOR ZARRO’S rasping voice deepened into a reverberating thunder.

“I can turn aside that oncoming dark star, if I am given power to do so in time!” he shouted. “I alone! I am master of forces unknown to your ignorant scientists, for I am not really a native of this System at all. Who I am or what I am does not matter in this emergency.

“I am going to form a legion of men who believe in me and will help me avert this peril—a Legion of Doom! But to prepare the forces that can turn aside the onrushing menace, I must have complete authority over all the resources of the System. I and my Legion must have temporary dictatorship over the System, if this terrible danger is to be averted.”

The figure of Doctor Zarro vanished from the televisor screen, leaving the operator and the mate of the Pallas thunderstruck.

“Who the devil was that?” gasped the stocky mate. “He didn’t look completely human!”

The young operator shook his head dazedly. Now the Earth Spaceport dispatcher, reappearing in the televisor, cried:

“Did you get that broadcast of the man who called himself Doctor Zarro? He crowded onto all wave-bands—every televisor in the whole System heard him!”

The dispatcher switched hastily off. Young Sparks looked excitedly up at the mate.

“Do you suppose there’s anything to his warning? If a dark star really is coming toward the System—”

“Nuts, there can’t be anything to it,” the mate declared. “It’s just a publicity stunt, but a queer one.”

“It didn’t sound like a stunt,” Sparks muttered uncertainly.

He pressed switches, tuning in on many stations. A kaleidoscope of faces passed across the televisor screen. A hurricane of messages was being flashed back and forth between planets, concerning the startling broadcast of the self-styled Doctor Zarro.

“He’s sure stirred up the System!” the operator declared. “And judging from the messages, not everybody is as skeptical as you.”

A buzzer sounded from atop the televisor set.

“General Government Call!” exclaimed Sparks, his youthful face stiffening. He reached and touched a stud.

An official of the System Government appeared in the televisor. He spoke with decisive firmness.

“This is to inform the System peoples that the so-called Doctor Zarro who broadcast a warning tonight is merely a cheap faker trying to scare the System,” said the official. “His assertions are not true. Astronomers have quickly checked the position in space he gave, and found nothing. The dark star does not exist!”

“What did I tell you?” scoffed the first mate as the System official switched off. “Just a crazy fake, that’s all.”

“Maybe,” muttered the operator. “But that man didn’t look like a faker. He looked queer, powerful—superhuman!”

“Rats—he’s just a crank alarmist,” repeated the stocky mate. “The Planet Police will soon hunt him down.”

BUT the Planet Police did not hunt Doctor Zarro down. Two weeks later the Mercurian newscaster was announcing:

“—and so the Planet Police have been completely unable to find the mysterious Doctor Zarro who made that broadcast, for his wave was of a strange new type whose source could not be located or analyzed.

“Karthak, Saturn: A disastrous atomic explosion in this colony today took toll of—”

The crowd of chromium-miners and engineers in this little drinking-shop in one of the Twilight Cities of Mercury paid no further attention to the news bulletins. One of them, a big, bald Earthman miner, had started arguing with a little Mercurian engineer.

“I tell you, I heard that broadcast,” the Mercurian insisted, “and that Doctor Zarro wasn’t any Earthman! He looked—”

“Look—there he is now!” yelled one of the crowd, pointing at the televisor.

They stared stupefiedly. The newscaster had been crowded off the ether, and the tall, gaunt, burning-eyed image of Doctor Zarro had appeared in the screen.

“You did not believe my warning, people of the nine worlds,” Doctor Zarro thundered, “you chose to believe your stupid ‘scientists’ instead. But now you shall see for yourself. The dark star approaching is now grown so large that it can be seen in small telescopes.

“Look for yourselves to the position in space I mentioned, and you will see that monster dead sun that is coming nearer to us each fateful minute. Look—and see for yourselves whether your ‘scientists’ or Doctor Zarro was right.”

The figure of Doctor Zarro vanished from the televisor, leaving the gathered miners and engineers gasping.

“Another fake warning!” cried the bald Earthman.

“I wonder,” muttered the little Mercurian engineer. He turned to a younger Mercurian. “Atho, you have a small telescope, haven’t you? Get it and set it up—we’ll see for ourselves.”

Presently, in the dark street of the metal Mercurian city, they were crowded around the small electro-telescope that was pointed toward a spot in the constellation Sagittarius.

“There is something there!” the young Mercurian cried. “I can see it!”

One by one, they stared through the eyepiece. They saw a tiny disk of darkness out there in the Milky Way.

“It’s a dark star, all right,” muttered the little engineer. “And it must be of great size, to present a visible disk far outside the System.”

THE motley interplanetary group of men looked at each other. A chill of doubt had settled on them.

“If a dark star is rushing toward the System, it will wreck the nine worlds as Doctor Zarro warns!” cried a wide-eyed Venusian. “Maybe we ought to give him the System-wide authority he asks for.”

“Aw, I still don’t believe it,” declared the bald Earthman miner. “Let’s see what the Government has to say on it.”

They crowded back to the televisor in the drinking shop. A Government announcer was on.

“People of the System, our scientists have now located a dark body of some kind in Sagittarius,” admitted the official; “But there is no danger from it! As far as the scientists have ascertained, it has almost no mass. So there’s nothing to fear.”

“See?” exclaimed the bald Earthman miner triumphantly. “I told you it was all nonsense.”

But the others looked worried. One of them, the younger Mercurian, voiced what all were thinking.

“The scientists said at first there was no dark star at all! Now they admit that Doctor Zarro was right, that there is a dark star. They claim it lacks sufficient mass to harm us, even though it’s big. Suppose the scientists are wrong again? Suppose Doctor Zarro’s warning is right?”

They looked at each other in wild surmise.

“If it is, then Doctor Zarro is the only one who can save us from the dark star! He was the one who told us about it when our scientists denied even its existence—”

The bald miner shook his head. Like all modern people, he had always had complete faith in the scientists of the System. That faith was still unshaken, even though Doctor Zarro had proved the scientists wrong once.

“I still take our scientists’ word against this mysterious Doctor Zarro’s,” he declared stubbornly. “They’d tell us if there was any real danger—”

This particular Earthman might persist in his faith. Others, in various quarters of the System, were losing it rapidly.

“There is danger! Terrible danger to the whole System! And only Doctor Zarro can avert it!”

The speaker was an Earthman colonist of Saturn, a deeply-tanned man of forty whose face could not conceal his deep-seated worry.

His wife and family and a few friends were gathered with him in his ranchhouse living room. Outside in the night stretched the vast plains of Saturn, with lanky Saturnians riding to and fro on their grotesque steeds in the light of the brilliant moons, herding the queer planetary cattle.

“The dark star exists—the scientists can’t dispute that—and it’s coming on toward the System at terrible speed, judging from the way its visible size increases,” the rancher continued earnestly. “If it isn’t turned aside somehow it will wreck the whole System. And Doctor Zarro’s the only one who can possibly turn it aside.”

“How do you know that even Doctor Zarro can do that?” demanded a Colonial Office clerk skeptically.

“I don’t know, but who could do it if he can’t? He discovered the approaching dark star long before the scientists could even see it. Hence, he must have powers greater than any known to our science. I say: give him the System-wide power he asks, and let him do what he can.”

“It means setting him up as a dictator over the whole System,” pointed out a neighbor Earthman rancher.

“It’s better to have a temporary dictator than to see the nine worlds wrecked by a catastrophe!”

The Earthman voiced what more and more people in the System were thinking. The scientists had been proved wrong once by Doctor Zarro. What if they were wrong again? The answer to that meant life or death for the System.

MORE and more people were proclaiming that they believed Doctor Zarro’s warnings. And the mysterious prophet’s followers, his Legion of Doom, had appeared throughout the System. They all wore a black, disklike emblem on their sleeves and carried a similar emblem on the bows of their space cruisers. They sped through the spaceways of the alarmed System, mysterious couriers of the enigmatic Doctor.

“Doctor Zarro always broadcasts at this time,” the rancher’s wife was saying. “Let’s see if he’s on tonight.”

They switched on the televisor. Minutes later, the impressive figure of the doctor crowded on the screen.

“People of the System, your scientists have told you there was no danger,” he shouted. “But where are those scientists now? Where is Robert Jons, the Mercurian astronomer who ridiculed my warnings? Where is Henry Gellimer, the astrophysicist who denounced me as a faker? Why have the great scientists who laughed at my warnings disappeared?

“Those scientists have escaped from the Solar System to avoid being trapped by the coming catastrophe!” Doctor Zarro thundered. “They have fled with their families, going outside the System in space ships to wait until the catastrophe is over, and then they will return to whatever worlds are spared. They are saving themselves, while you billions of people who believed in them will perish!”

As the dark prophet vanished from the screen, the Earthman rancher and his friends, stunned, looked at each other.

“If those scientists have really fled from the System, that proves that Doctor Zarro is right!” cried the rancher.

“We don’t know yet that it’s really happened—Doctor Zarro may be lying about it,” said the clerk worriedly.

“Here’s a Government bulletin!”

The harassed face of a System Government official on a System-wide hookup appeared in the screen, for the Government was now following each of Doctor Zarro’s broadcasts with reassuring statements. This statement was not reassuring.

“People of the System, it is true that many of our most eminent scientists and their families have disappeared. But we are sure they have not fled—we believe foul play is responsible. We beg the System not to credit the statements of this Doctor Zarro, but to have faith that there is no danger—”

“Have faith?” cried the rancher of Saturn. “How can we have faith in the scientists’ assurance that there’s no danger, when they’ve fled to save themselves? There is danger—and Doctor Zarro is the only chance we have to avert it!”

“I believe now you’re right,” his neighbor rancher agreed troubledly. “We’ll have to force the Government to turn over all power to Doctor Zarro!”

IN FRONT of the great tower that housed the System Government, in the city of New York on Earth, a vast crowd was demonstrating this night.

“The President—and Council—must resign—and yield their power—to Doctor Zarro—and the Legion—till the danger is past!” the crowd was shouting in unison.

James Carthew, the President of the System Government, stood at the window of his office, looking down at the surging, terrorized throng. His secretary waited anxiously beside him.

“This can’t go on,” Carthew said tightly as he looked down at the swaying crowd being held back by police. “A little more of this, and they’ll overturn the Government by force.”

His fist clenched.

“This Doctor Zarro is a cunning plotter playing upon the fears of the System to attain dictatorial power! He’s the most diabolically ingenious schemer that has ever threatened this Government!”

North Bonnel, the young secretary, shook his head in troubled doubt.

“But, sir,” he reminded, “Doctor Zarro did foretell the coming of the dark star, when our greatest scientists with the most powerful telescopes could not even see it.”

“I know, and I can’t understand that,” Carthew admitted. “But that doesn’t change the fact that we’re up against a devilish scheme to usurp power over the whole System. There can’t be any real danger in that approaching dark star when it has such a ridiculously low mass. The public only thinks there is danger, and Doctor Zarro is fanning their fears higher every hour.”

The door of the office burst open. The man who entered wore a dark uniform with silver stars on the shoulders. He was Halk Anders, commander of the Planet Police.

“Sir, I have to report,” he told the President breathlessly as he saluted, “that those crowds are getting out of hand. We can hardly hold them out of this building now. I’ve had calls from headquarters on the other planets, and the people there are rioting too, calling for Doctor Zarro to be given full emergency authority.”

Carthew’s lined face whitened.

“Haven’t you been able yet to locate this Doctor Zarro?” he cried. “If we could arrest him and stop those inflammatory broadcasts of his—”

The stocky commander shook his head.

“We’ve been unable to find Doctor Zarro’s headquarters. His broadcasts are on a new-type wave that we can’t track down. We’ve tried to trail the ships of his Legion of Doom, but they always manage to give us the slip in space.”

“What about Jons and Gellimer and all the other scientists who vanished?” Carthew asked. “Have you learned anything?”

“No, sir.”

North Bonnel turned haggardly to his superior.

“What are we going to do, sir? If the public terror increases like this, the Government will be in Doctor Zarro’s hands in a week!”

JAMES CARTHEW’S pale face set. He looked out through the eastern window of the tower room, at the fun moon that was rising majestically in the heavens like a great silver shield.

“There is one man who can smash Doctor Zarro’s plot, if anybody can,” he muttered. “I did not want to call upon him before this, for he is not the kind of man to be annoyed with matters the regular authorities can handle—”

The secretary stiffened. His lips trembled.

“You mean—Captain Future?”

“Yes, Captain Future,” the President said, his eyes still fixed on the rising moon. “If anybody can stop Doctor Zarro and his Legion, Captain Future and those three weird comrades of his can do it.”

He turned abruptly, desperate determination written on his kindly, bewildered face.

“Televise an order to have the North Pole signal-flare set off at once, Bonnel!”

A half hour later, amid the frozen wastes of eternal ice at the North Pole, there blossomed a huge flower of flame as a great, dazzling magnesium flare was detonated.

Far out in space that brilliant beacon was visible. Throbbing, winking and blinking, it cast its beams out through the void in silent, urgent appeal.

“Calling Captain Future!”

Calling the great, glamorous foe of evil, to a struggle with the mysterious Doctor Zarro’s plot against misled humanity!

Chapter II

The Futuremen

A BARREN, deathly white waste stretched across the surface of the Moon. Beneath the glare of the blazing sun, the lunar plains rolled in eternal silence toward the colossal craters that towered like menacing jagged fangs. Upon this desolate world there was no air, no sound, and no human life—except in one place.

Upon the floor of Tycho Crater glittered something like a round crystal lake. It was a big, glassite window set in the lunar rock. Underneath that window, excavated out of the soft rock, was the artificial cavern that was the laboratory and home of the most famous man in the System—Captain Future.

The big laboratory of the cavern home was bathed in light from the window above it. Here loomed mechanisms and racks of instruments in bewildering array. Giant generators and condensers that could furnish limitless atomic power. Big telescopes and spectro-telescopes whose tubes protruded through the lunar surface.

Chemical and electrical apparatus of bewildering complexity and design. All the crowded equipment of the System’s supreme master of science!

The two individuals working tensely in a corner of the laboratory could be heard over the throbbing of a machine.

“Time to shift the electron-flow, Simon?” the deep, clear voice of one was asking.

“Not yet, Curtis,” answered the other’s voice, a rasping, metallic, unhuman one. “Transmutation is not complete yet.”

These two were working with a spherical machine into which the great atomic generators were pouring vast power.

One of the two was a big, red-headed young man in a gray synthesilk zipper suit. His lithe, broad-shouldered figure towered six feet four. His tanned, handsome, debonair face and flashing gray eyes had a rollicking humor in them that could not hide keen intelligence and deep purpose.

He wore a big ring on his left hand—a ring whose nine jewels were motivated by a tiny atomic power engine that kept them moving slowly around a glowing central jewel. This ring, whose jewels represented the nine worlds, was known to the whole System as the identifying emblem of Captain Future, the wizard of science and the implacable foe of evil.

Captain Future—or Curtis Newton, by the name so few knew—stood ready by the lever of the spherical machine. On a pedestal, watching the gauges of the mechanism, was his fellow-worker.

This was Simon Wright, the Brain. He was just that—a living human brain that had no body. Instead, his brain was housed in a square, transparent serum-case, in the front of which was his resonator speech apparatus, on the stalks of which in turn were his lens-eyes.

“Transmutation’s almost complete now,” the Brain declared in his metallic artificial voice, his glass lens eyes closely watching the gauges. “Stand ready to shift the electron flow.”

A moment later he spoke quickly. “Now!”

Curt Newton slammed down the lever. The throbbing of power into the spherical machine ceased.

The red-headed scientific wizard undamped a door and opened it. Out of the mechanism poured a stream of white powder.

“That’s done it!” Curt exclaimed. “A hundred pounds of copper, transmuted into pure isotopic boron.”

HE STEPPED back and mopped his brow, and then grinned at the Brain. “Whew, that was a job! But it will save us a trip all the way to Uranus, to get that rare isotope.”

“Aye, lad,” rasped the Brain. “This transmutation of elements is one of your greatest achievements yet.” Curt’s gray eyes twinkled at him.

“You’re an old fraud, Simon,” he accused. “You know as well as I do that I could never have achieved it if you hadn’t worked with me.”

At that moment, there was a sudden explosion of angry, arguing voices from another chamber of the cavern home. One was a loud, Booming, mechanical-sounding voice. The other voice was hissing, sibilant and furious.

“Grag and Otho are at each other again!” exclaimed Captain Future impatiently. “I swear those two will drive me crazy yet.”

He raised his voice in a call. “Grag! Otho!”

Two creatures of unhumanly weird appearance entered the laboratory in answer to his call.

One of them was a rubbery white android, or synthetic man. Otho, the android, was manlike in figure, his synthetic flesh having been molded into human form when he had been made. But his hairless white head and face, his slitted green eyes that were flashing now with anger, were not like any human’s. Nor could any human move with his wonderful quickness and agility.

Grag, the metal robot, was the other disputant. Towering seven feet high, his mighty metal arms hinted incredible strength. The chief features in his bulbous metal head were his two photo-electric eyes that gleamed with living light, and the mouthlike opening of his speech mechanism. There was no creature in the whole System stronger than Grag, the robot.

Perched upon Grag’s shoulder was a queer, bearlike little animal of inorganic silicate flesh, with strong paws, a sharp, inquisitive snout, and bright little black eyes. It was a moon-pup, one of the strange non-breathing creatures found on the lunar plains, who assimilated food elements by direct ingestion of the mineral they could crush in their powerful teeth. The little gray creature was contentedly chewing on a piece of copper now.

“Now what’s the trouble between you two?” Captain Future demanded of the robot and android. “Can’t Simon and I work for a minute without you two getting into your arguments?”

“It’s Grag’s fault!” hissed Otho furiously. He pointed to the little gray bearlike animal. “That damned moon-pup pet of his has eaten up one of my best pistols!”

GRAG, the robot, cuddled the little gray moon-pup protectively with a great metal hand. “It’s not Eek’s fault, master,” he told Captain Future in loud indignation. “Eek was hungry—and he loves copper.”

“Either that moon-pup leaves here or I leave!” stormed the android. “The beast eats any metal it can get its paws on—and when it gets hold of some precious metal, it gets howling drunk on it! It’s got a lot of other habits that make it a pest. It was crazy of Grag to catch the cursed thing and make a tame pet of it.”

“We humans like to have pets,” the robot defended.

“Otho does not understand, master, because he is not human like us.”

“Not human like you?” Otho howled furiously. “Why, you walking machine-shop, anyone can see that I’m a flesh-and-blood human while you’re nothing but a clever mechanism! If I—”

“Now don’t start that argument again!” Captain Future interrupted hastily. “I’ve heard enough of it.”

“Aye, and so have I,” rasped Simon Wright, the Brain, his lens-eyes dourly surveying the two disputants. “You two are always arguing about which is the most human. And I, who really was human once, can tell you that it’s nothing worth arguing about.”

“Simon is right,” Curt Newton said severely. “Every time you two have any time on your hands, you start scrapping with each other, and I’m getting tired of it.”

Despite his severity of tone, there was a fond twinkle of affection in the gray eyes of the big red-headed scientific adventurer, as he surveyed the robot and the android and the Brain.

These were the Futuremen, the loyal trio of comrades who had fought and sailed around the whole System with him! These three weird comrades of his, un-human in form yet superhuman in abilities, had stood at his side in more than one great struggle out in the solar spaces. And, furthermore, the three had reared Curt Newton from babyhood to manhood, in this very cavern home on the Moon.

Twenty-five years before, Captain Future’s parents had come secretly to the moon. Roger Newton was a young Earth biologist who dreamed a great dream. He hoped to create life—artificial, intelligent living creatures who could serve mankind. But his work was in danger. Certain ambitious men coveted his scientific discoveries and tried to steal them.

Roger Newton had decided to seek refuge on the wild, uninhabited Moon. He had sailed secretly in a small rocket for the Moon. And with him had gone his young wife, Elaine, and his loyal co-worker and assistant, Simon Wright—the Brain.

Simon Wright had been a famous, aging scientist who was about to die of incurable disease. Newton had by brilliant surgery removed Simon’s brain and transferred it into a special serum-case. Ever since, the Brain had been his most loyal friend.

Newton and his young wife and the Brain had reached the Moon safely, and had built an underground home beneath Tycho Crater. There, soon after their arrival, a son was born to the man and woman—a boy whom they named Curtis. And there they began the work of creating artificial living creatures.

GRAG, the robot, was the first creature created by Roger Newton and the Brain. Their second creation was not of metal but of synthetic plastic flesh molded into a manlike android—Otho, the synthetic man. These two artificial creatures, intelligent, strong faithful, showed Roger Newton that he had at last realized his dream.

Then disaster struck. The evil plotters who coveted Newton’s scientific secrets had trailed him to the Moon. There was a fight—and Roger Newton and his young wife were slain, before the robot and the synthetic man killed the murderers.

Dying, Elaine Newton entrusted her infant son to the care of the three unhuman creatures, Brain, robot and android. She begged them to rear him to manhood and implant in him a hatred of all those who used scientific gifts for evil ends—to train him as a relentless foe of an such as would oppress or exploit the System people.

Simon Wright and Grag and Otho had kept that promise. They had reared little Curtis Newton to manhood. And the Brain, with its wonderful scientific knowledge, had so schooled him that he became a wizard of scientific ability surpassing his teacher. Grag, the robot, strongest of living beings, had fostered his strength until it was superhuman. And Otho the android, swiftest and most agile of all creatures, had taught him unmatchable speed and deftness.

Thus Curtis Newton had grown to manhood on the lonely Moon, with his three unhuman tutors. When he had reached manhood, the Brain had told him the story of his origin, and had repeated the dying wish of his mother that he become champion of the System’s peoples against those who would oppress them.

“Will you take up this crusade against interplanetary evil, Curtis?” the Brain had asked. “Will you embark on this crusade, this fight for the future of the System?”

Curtis Newton had made his fateful decision, one that was to change history.

“Yes, Simon—someone has to stand up for the System peoples against their exploiters. And, with you three helping me, I’ll do my best.”

He had added half-humorously: “Since you say I’ll be fighting for the future of the System, I think I’ll call myself—Captain Future.”

As Captain Future, then, Curt had offered his services to the System President in the war against interplanetary crime. At first doubtful of this strange, redheaded young man, the President had in a desperate emergency called upon his aid.

Captain Future and the Futuremen had demonstrated their power, swiftly, relentlessly. Since then, the President had called him time and again by the agreed signal. And time and again, Curt Newton and his three strange, loyal comrades had gone forth in perilous struggle.

CURT was thinking of all that now, as he faced his three comrades.

“You two are more than human to me,” he told Grag and Otho impulsively. “So why can’t you quit this continual jealousy about which is the most human?”

“Otho is too overbearing,” Grag boomed, cuddling the moon-pup in his metal arm. “He should remember that I was made before he was.”

“Of course you were—you were such a bad job that they had to try again and make me before they were satisfied,” Otho jeered, with a mocking gleam in his slitted green eyes.

“Will you let him talk so, master?” appealed Grag angrily to Curt Newton. “He—”

“The signal!” cried the Brain suddenly.

Simon’s lens-eyes had glanced up through the window overhead at the great green sphere of Earth. The cry of the Brain made the other three look up instantly.

There upon the great cloudy green planet hanging in starry space, upon the white patch at the North Pole, a blazing pinpoint of light was pulsing and throbbing.

“It is the signal!” Captain Future said gravely. “We’re needed.”

Captain Future’s debonair tanned face had changed, grown grim. His nostrils were flaring, his brilliant gray eyes had something chill and hard as steel in them now.

The Futuremen were gripped by the same strange emotion. The call from Earth! The tocsin that summoned these four to action! It was for this call that they waited through long weeks, living and working in the lunar laboratory.

Captain Future’s voice rang like a silver trumpet summoning to battle.

“To the Comet! That call admits of no delay. The President never calls for nothing.”

“Pick me up, Grag,” rasped the Brain’s calm, metallic voice.

The robot picked up the handle of the Brain’s case. With the moon-pup clinging to his other arm, Grag started with hasty strides after Curt Newton and Otho.

Ten minutes later a small ship shaped like an elongated tear-drop rose from an underground hangar on the lunar surface. It was the Comet, super-swift craft of the Futuremen, known far and wide through the System as the swiftest ship in space.

Two hours later, so swift was its flight, the Comet screamed down through the stratosphere of Earth’s night side. Curt Newton dropped the little craft straight toward the great Government Tower that rose above all other structures of brilliant New York.

The Comet came to rest on the truncated tip of the tower. As Curt and the Futuremen emerged, they saw in the plaza far below a great crowd that surged riotously against a line of Police.

Curt’s lip tightened.

“Something’s damned wrong, from the look of things. Come on—hurry—”

They hastened down a stairway that led directly into the private office of the System President. The three men in that office, Carthew, his secretary, and Commander Anders of the Planet Police, spun around startledly.

“Captain Future!” cried Carthew, his voice shrill with relief, his fine face working as he came hastily forward.

YOUNG Bonnel and the burly Commander stared, not without awe, at the tall young wizard of science and his companions.

Curt Newton’s big figure radiated power and confidence as he stood there, the weird trio of the Futuremen behind him—giant Grag, the Brain he held, and the rubbery android.

“What’s wrong, sir?” Curt demanded of the President. “What does that rioting crowd down there want?”
