by Unknown
He was tensed for a spring as Schwartzmann paused. From the wall beyond him a red light was flashing; a crystal flamed forth with the intense glare of a thousand fires. It checked the curses on the other's thick lips; it froze Harkness to a rigid statue in the darkness of his little room.
* * * * *
An emergency flash broadcast over the world! It meant that the News Service had been commandeered. This flashing signal was calling to the peoples of the earth!
What catastrophe did this herald? Had it to do with the Dark Moon? Not since the uprising of the Mole-men, those creatures who had spewed forth from the inner world, had the fiery crystal called!... It seemed to Harkness that Schwartzmann was hours in reaching the switch.... A voice came shouting into the room:
"By order of the Stratosphere Control Board," it commanded, "all traffic is forbidden above the forty level. Liners take warning. Descend at once."
Over and over it repeated the command--an order whose authority could not be disregarded. In his inner vision Harkness saw the tumult in the skies, the swift dropping of huge liners and great carriers of fast freight, the scurrying of other craft to give clearance to these monsters whose terrific speed must be slowly checked. But why? What had happened? What could warrant such disruption of the traffic of the world? His tensed muscles were aching unheeded; his sense of feeling seemed lost, so intently was he waiting for some further word.
"Emergency news report," said another voice, and Harkness strained every faculty to hear. "Highline ships attacked by unknown foe. Three passenger carriers of the Northpolar Short Line reported crashed. Incomplete warnings from their commanders indicate they were attacked. Patrol ship has spotted one crash. They have landed beside it and are reporting....
"The report is in; it is almost beyond belief. They say the liner is empty, that no human body, alive or dead, is in the ship. She was stripped of crew and passengers in the air.
"We await confirmation. Danger apparently centered over arctic regions, but traffic has been ordered from all upper levels--"
The voice that had been held rigidly to the usual calm clarity of an official announcer became suddenly high-pitched and vibrant. "Stand by!" it shouted. "An S. O. S. is coming in. We will put it through our amplifiers; give it to you direct!"
* * * * *
The newscaster crackled and hissed: they were waiving all technical niceties at R. N. Headquarters, Harkness knew. The next voice came clearly, though a trifle faint.
"Air Patrol! Help! Position eighty-two--fourteen north, ninety-three--twenty east--Superliner Number 87-G, flying at R. A. plus seven. We are attacked!--Air Patrol!--Air Patrol!--Eighty-two--fourteen north, ninety-three--twenty--"
The voice that was repeating the position was lost in a pandemonium of cries. Then--
"Monsters!" the voice was shouting. "They have seized the ship! They are tearing at our ports--" A hissing crash ended in silence....
"Tearing at our ports!" Harkness was filled with a blinding nausea as he sensed what had come with the crash. The opening ports--the out-rush of air released to the thin atmosphere of those upper levels! Earth pressure within the cabins of the ship; then in an instant--none! Every man, every woman and child on the giant craft, had died instantly!
The announcer had resumed, but above the sound was a guttural voice that shouted hoarsely in accents of dismay. "Eighty-seven-G!" Schwartzmann was exclaiming, "--Mein Gott! It iss our own ship, the Alaskan! Our crack flyer!"
* * * * *
Harkness heard him but an instant, for another thought was hammering at his brain. The position!--the ship's position!--it was almost above his experimental plant! And Chet was there, and the ship.... What had Chet said? He would fly it in two days--and this was the second day! Chet had no radio-news; no instrument had been installed in the shop; they had depended upon the one in Harkness' own ship. And now--
Walt Harkness' clear understanding had brought a vision that was sickening, so plainly had he glimpsed the scene of terror in that distant cabin. And now he saw with equal clarity another picture. There was Chet, smiling, unafraid, proud of their joint accomplishment and of the gleaming metal shape that he was lifting carefully from its bed. He was floating it out to the open air; he was taking off, and up--up where some horror awaited.
"Monsters!" that thin voice had cried in a tone that was vibrant with terror. What could it be?--great ships out of space?--an invasion? Or beasts?... But Harkness' vision failed him there. He knew only that a fast ship was moored just outside. He had planned vaguely to seize it; he had needed it for his own escape; but he needed it a thousand times more desperately now. Chet might have been delayed, and he must warn him.... The thoughts were flashing like hot sparks through his brain as he leaped.
* * * * *
He bore the heavier body of Schwartzmann to the floor. He rained smashing blows upon him with a furious frenzy that would not be curbed. The weapon with its deadly detonite bullet came toward him. In the same burst of fury he tore the weapon from the hand that held it; then sprang to his feet to stand wild-eyed and panting is he aimed the pistol at the cursing man and dragged him to his feet.
"The ship!" he said between heavy breaths, "--the ship! Take me to it! You will tell anyone we meet it is all right. One word of alarm, one wrong look, and I'll blow you to hell and make a break for it!"
The pistol under Harkness' silken jacket was pressed firmly into Schwartzmann's side; it brought them safely past excited guards and out into the storm; it held steady until the men had fought their way through blasts of rain to the side of the anchored ship. Not till then did Schwartzmann speak.
"Wait," he said. "Are you crazy, Harkness? You can never take off; the trees are close; a straight ascent is needed. And the wind--!"
He struggled in the other's grasp as Harkness swung open the cabin door, his fear of what seemed a certain death overmastering his fear of the weapon. He was shouting for help as Harkness threw him roughly aside and leaped into the ship.
Outside Harkness saw running figures as he threw on the motors. A pistol's flash came sharply through the storm and dark. A window in the chateau flashed into brilliance to frame the figure of a girl. Tall and slender, she leaned forward with outstretched arms. She seemed calling to him.
* * * * *
Harkness seized the controls, and knew as he did so that Schwartzmann was right: he could never lift the ship in straight ascent. Before her whirling fans could raise her they would be crashed among the trees.
But there were two helicopters--dual lift, one forward and one aft. And Walt Harkness, pilot of the second class, earned immediate disbarment or a much higher rating as he coolly fingered the controls. He cut the motor on the big fan at the stern, threw the forward one on full and set the blades for maximum lift, then released the hold-down grips that moored her.
The grips let go with a crashing of metal arms. The bow shot upward while a blast of wind tore at the stubby wings. The slim ship tried to stand erect. Another furious, beating wind lifted her bodily, as Harkness, clinging desperately within the narrow room, threw his full weight upon the lever that he held.
The full blast of a detonite motor, on even a small ship, is terrific, and the speedster of Herr Schwartzmann did not lack for power. Small wonder that the rules of the Board of Control prohibit the use of the stern blast under one thousand feet.
The roaring inferno from the stern must have torn the ground as if by a mammoth plow; the figures of men must have scattered like leaves in a gusty wind. The ship itself was racked and shuddering with the impact of the battering thrust, but it rose like a rocket, though canted on one wing, and the crashing branches of wind-torn trees marked its passage on a long, curving slant that bent upward into the dark. Within the control room Walter Harkness grinned happily as he drew his bruised body from the place where he had been thrown, and brought the ship to an even keel.
* * * * *
Nice work! But there was other work ahead, and the smile of satisfaction so
on passed. He held the nose up, and the wireless warning went out before as the wild climb kept on.
Forty thousand was passed; then fifty and more; a hundred thousand; and at length he was through the repelling area, that zone of mysterious force, above which was a magnetic repulsion nearly neutralizing gravity. He could fly level now; every unit of force could be used for forward flight to hurl him onward faster and faster into the night.
Harkness was flying where his license was void; he was flying, too, where all aircraft were banned. But the rules of the Board of Control meant nothing to him this night. Nor did the voluble and sulphurous orders to halt that a patrol-ship flashed north. The patrol-ship was on station; she was lost far astern before she could gather speed for pursuit.
Walter Harkness had caught his position upon a small chart. It was a sphere, and he led a thin wire from the point that was Vienna to a dot that he marked on the sub-polar waste. He dropped a slender pointer upon the wire and engaged its grooved tip, and then the flying was out of his hands. The instrument before him, with its light bulbs and swift moving discs, would count their speed of passage; it would hold the ship steadily upon an unerring course and allow for drift of winds. The great-circle course was simple; the point he marked was drawing them as if it had been a magnet--drawing them as it drew the eyes of Walt Harkness, staring strainingly ahead as if to span the thousands of miles of dark.
CHAPTER III - The Space Terror
The control room was glassed in on all sides. The thick triple lenses were free from clouding, and the glasses between them kept out the biting cold of the heights. The glass was strong, to hold the pressure of one atmosphere that was maintained within the ship. The lookouts gave free vision in all directions except directly below the hull, and a series of mirrors corrected this defect.
But Walt Harkness had eyes solely for the black void ahead. Only the brilliant stars shone now in the mantle of velvety night. No flashing lights denoted the passing of liners, for they were safe in the harbor of the lower levels. He moved the controls once to avoid the green glare of an ascending area, then he knew that there were no ships to fear, and let the automatic control put him back on his course.
Before him, under a hooded light, was a heavy lens. It showed in magnification a portion of the globe. There were countries and seas on a vari-colored map, and one pin-point of brilliance that marked his ever-changing position.
He watched the slow movement of the glowing point. The Central Federated States of Europe were behind him; the point was tracing a course over the vast reaches of the patchwork map that meant the many democracies of Russia. This cruiser of Schwartzmann's was doing five hundred miles an hour--and the watching man cursed under his breath at the slow progress of the tiny light.
But the light moved, and the slow hours passed, while Harkness tried to find consolation in surmises he told himself must be true.
Chet had been delayed, he insisted to himself; Chet could never have finished the work in two days; he had been bluffing good-naturedly when he threatened to fly the ship alone....
* * * * *
The Arctic Ocean was beneath. The tiny light had passed clear of the land on the moving chart.
He would be there soon.... Of course Chet had been fooling; he was always ready for a joke.... Great fellow, Chet! They had taken their training together, and Chet had gone on to win a master-pilot's rating, the highest to be had....
Another hour, and a rising hum from a buzzer beside him gave warning of approach to the destination he had fixed. The automatic control was warning him to decelerate. Harkness well knew what was expected of the pilot when that humming sounded; yet, with total disregard for the safety of his helicopters, he dived at full speed for the denser air beneath.
He felt the weight that came suddenly upon him as he drove through and beneath the repelling area, and he flattened out and checked his terrific speed when the gauges quivered at forty thousand.
Then down and still down in a long, slanting dive, till a landmark was found. He was off his course a bit, but it was a matter of minutes until he circled, checked his wild flight, and sank slowly beneath the lift of the dual fans to set the ship down as softly as a snowflake beside a building that was dark and forbiddingly silent--a lonely outpost in a lonely waste.
No answer came to his hail. The building was empty; the ship was gone. And Chet! Chet Bullard!... Harkness' head was heavy on his shoulders; his feet took him with hopeless, lagging steps to his waiting ship. He was tired--and the long strain of the flight had been in vain. He was suddenly certain of disaster. And Chet--Chet was up there at some hitherto untouched height, battling with--what?
* * * * *
He broke into a stumbling run and drew himself within the little ship. He was helpless; the ship was unarmed, even if the weapons of his world were of use against this unknown terror; but he knew that he was going up. He would find Chet if he could get within reach of his ship; he would warn him.... He tried to tell himself that he might yet be in time.
The little cruiser rose slowly under the lift of the fans; then he opened the throttle and swept out in a parabolic curve that ended in a vertical line. Straight up, the ship roared. It shot through a stratum of clouds. The sun that was under the horizon shone redly now; it grew to a fiery ball; the earth contracted; the markings that were coastlines and mountains drew in upon themselves.
He passed the repelling area and felt the lift of its mysterious force--the "R. A. Effect" that permitted the high-level flying of the world. His speed increased. It would diminish again as the R. A. Effect grew less. Record flights had been made to another ten thousand.... He wondered what the ceiling would be for the ship beneath him. He would soon learn....
He set his broadcast call for the number of Chet's ship. They had been given an experimental license, and "E--L--29-X" the instrument was flashing, "E--L--29-X." Above the heaviside layer that had throttled the radio of earlier years, he knew that his call from so small an instrument as this would be carried for hundreds of miles.
He reached the limit of his climb and was suddenly weightless, floating aimlessly within the little room; the ship was falling, and he was falling with it. His speed of descent built up to appalling figures until his helicopters found air to take their thrust.
And still no answering word from Chet. The cruiser was climbing again to the heights. The hands of Harkness, trembling slightly now, held her to a vertical climb, while his eyes crept back to the unlit plate where Chet's answering call should flash. But his own call would be a guide to Chet; the directional finders on the new ship would trace the position of his own craft if the new ship were afloat--if it were not lying crushed on the ice below, empty, like the liners, of any sign of life.
* * * * *
His despairing mind snapped sharply to attention. His startled jerk threw the ship widely from her course. A voice was speaking--Chet's voice! It was shouting in the little room!
"Go down, Walt," it told him. "For God's sake, go down! I'm right above you; I've been fighting them for an hour; but I'll make it!"
He heard the clash of levers thrown sharply over in that distant ship; his own hands were frozen to the controls. His ship roared on in its upward course, the futile "E--L--29-X" of his broadcast call still going out to a man who could not remove his hands to send an answer, but who had managed to switch on his sending set into which he could shout.
Harkness was staring into the black void whence the wireless voice had come--staring into the empty night. And then he saw them.
The thin air was crystal clear; his gaze penetrated for miles. And far up in the heights, where his own ship could never reach and where no clouds could be, were diaphanous wraiths. Like streamers of cloud in long serpentine forms, they writhed and shot through space with lightning speed. They grew luminous as they moved living streamers of moonlit clouds.... A whirling cluster was gathered into a falling mass. Out of it in a sharp right turn shot a projectile, tiny and glistening against the velv
et black. The swarm closed in again.... There were other lashing shapes that came diving down. They were coming toward him.
And, in his ears, a voice was imploring: "Down! down! The R. A. tension may stop them!... Go down! I am coming--you can't help--I'll make it--they'll rip you to pieces--"
The wraith-like coils that had left the mass above had straightened to sharp spear-heads of speed. They were darting upon him, swelling to monstrous size in their descent. And Walt Harkness saw in an instant the folly of delay: he was not helping Chet, but only hindering.... His ship swung end for end under his clutching hands, and the thrust of his stern exhaust was added to the pull of Earth to throw him into a downward flight that tore even the thin air into screaming fragments.
* * * * *
One glance through the lookouts behind him showed lashing serpent forms, translucent as pale fire; impossible beasts from space. His reason rejected them while his eyes told him the terrible truth. Despite the speed of his dive, they were gaining on him, coming up fast; one snout that ended in a cupped depression was plain. A mouth gaped beneath it; above was a row of discs that were eyes--eyes that shone more brightly than the luminous body behind--eyes that froze the mind and muscles of the watching man in utter terror.
He forced himself to look ahead, away from the spectral shapes that pursued. They were close, yet he thrilled with the realization that he had helped Chet in some small degree: he had drawn off this group of attackers.
He felt the upthrust of the R. A. Effect; he felt, too, the pull of a body that had coiled about his ship. No intangible, vaporous thing, this. The glass of his control room was obscured by a clinging, glowing mass while still the little cruiser tore on.
