They were moving rapidly across the field tarmac toward the battered rocket ship in its starting cradle, Duval's feet fairly twinkling to match Gerry's eager strides. The paralysis ray swung at her side. She nodded incisively.
"I see what you mean. We dive straight into the heart of Jupiter to gather terrific momentum, then cut over in a hump and utilize our speed to draw clear and make our objective. Splendid! I knew there must be some rocket-buster around here with the stuff to make this trip."
Duval beamed.
"You are willing to risk the life with me?"
"Perfectly."
Drawn by curiosity, some of the pilots drifted around as Duval made a swift final check-up before taking off. A few, a bit embarrassed by anything like a display of emotion, diffidently shook the Frenchman's hand in a manner clearly indicating they never expected to see him again. Just before they scaled the entrance port, Bullwer poked his head inside.
"Say! You really gonna shoot for V, Frenchy?" he asked incredulously.
Duval drew himself up to every inch of his five feet. "And why not? If there is anyone who can it achieve, I, Duval, am he, is it not?"
Bullwer grinned.
"Maybe so. But I'll lay a week's pay you can't."
"Done!" And Duval slammed the port shut, nearly decapitating Bullwer. Flames spewed from the rocket-tubes in tenuous streamers along the ground; thunder shook the ship. Scarcely waiting for the motors to warm up properly, Duval poured on the power, and the strangely assorted couple took off on perhaps the most hazardous journey in the history of rocketry.
Chapter XII.
Re-birth
Gerry always remembered that trip with the breathless terror of a nightmare. Once in the ship, there was no time to adjust herself to the danger, none of the usual hours of preparation, of preliminary approach, during which one can screw up courage to the sticking point. Instead, one instant the clang of the port was ringing in her cars, the next, the booming of the engines, and all at once they were dropping like a plummet straight into the maw of the gigantic golden bubble of Jupiter, which burgeoned before them like a mighty blossom of disaster.
Duval was a grim figure strapped in the pilot's seat, his magic hands flying over the control board, delicately probing, guiding the old cracker-box ship miraculously, wary of indications of Jovian magnetic storms which would mean destruction for them. Completely ignoring the physical effects of acceleration, Duval soon had the rocket ship hurtling down at speeds she had never achieved before, and for which she was never built.
Soon the sinister, swirling globe of Jupiter filled every corner of the visi-screen. Duval spoke sharply without turning his bead.
"The straps, Mademoiselle! Make certain they are tight! Soon we must make our move!"
Gerry set her teeth grimly, watching with almost impersonal admiration the skill of Duval. Too late to turn back now; already a faint scream was audible as they bulleted through the extreme upper reaches of the Jovian atmosphere. Then Duval's fingers plunged downward on the firing keys, and the underrockets flowered crimson petals of flame.
The ship lurched, groaned hideously in every joint as if in some strange cosmic labor, striving to tear itself free. Instantly the steely fingers of Jupiter's gravity wrenched powerfully at the ancient bull. Seams squealed, ripping open as the rivets sprung; the plates twisted tortuously under the unprecedented strains. Air pressure dropped as the precious mixture whistled out through a dozen tiny vents. The obsolete air-o-stat pumped valiantly in a grim losing battle.
Temperature suddenly rose, rapidly becoming intolerable as the outer air became thicker and friction heated the hull. Sweat poured into Gerry's eyes, but she maintained her stoic calm.
The picture of Jupiter on the visi-screen was shifting erratically; a matter of a few seconds would tell the story. . . .
They made it. Their incredible velocity defeated the greedy powers of Jovian gravity. One final burst in which the rockettube flames burst completely around the ship's nose, obscuring everything, and they had cleared the "hump," missed the surface of Jupiter c1eanly and burst through the layers of upper atmosphere into open space again. Ahead, moving round to its assignation with the ship, was Satellite Five, barren and bright in the Jupiter-glow.
The rest was comparatively simple. Jupiter's gravity still had a strong claim on them; it was as if they were chained to the giant planet by a cosmic rubber band, which tightened inexorably the further they coasted away. Handling this mighty force with dexterity, Duval jockeyed the ship so it was barely moving when it reached the appointed spot in space. They came to rest with a jar that completed the wrecking of the ship, but they were safe.
Gerry took Duval's hand and squeezed hard.
"You were magnificent, Duval; I'll never forget it. But now we've got work to do. Ready?"
They piled into space-suits, Gerry seized the paralysis equipment, and the two left the wreckage. There was nothing moving in sight on the fairly level plane, spawled off by Jupiter's fierce heat when the System was young, whose horizon was a scant mile away. So they started walking. Gravitation was surprisingly strong, indicating unusual density. This fact, plus the intense cold which slows down the dance of the atoms, accounted for the fact that Five still retained remnants of an atmosphere.
The hikers even saw traces of water vapor, in form of frost. Occasionally they passed clumps of mossy or lichenous growth. Twice they observed colonies of sluglike creatures growing, reproducing, and dying with amazing rapidity. And then, like an enormous silver cigar looming over the horizon, The Ark came into view. It looked almost as large as the Satellite itself, and there was furious activity going on. A half-dozen suited figures scurried about the nose of The Ark. From the pilot house another figure was throwing out instruments to those below.
Gerry and Duval drew quickly near, and she shouted into her head-set, "Hey. Tommy! Tommy Strike!"
All the moving figures turned sharply, in varying attitudes of astonishment. Then one of them gestured sharply and came lumbering over the plain as fast as possible.
As the two from Ganymede moved forward, Duval tripped and sprawled ludicrously, though harmlessly, on his face. He scrambled carefully to his feet and bent over to see what had caused his humiliation. He uttered a sharp exclamation.
"Name of a pipe! What a monster of the most incredible!"
Gerry, too, stopped to examine the thing stretched out on the rocky ground. It was something beyond even Gerry's vast experience in extra-terrestrial life. From tip to tip it might have measured as much as twenty feet, and its ugly, warty gray hide was divided into armored sections along its entire length with soft spots between the plates. It was oval-shaped in lateral cross-section, something like a gigantic cut-worm that has been stepped upon but not quite squashed. Duval was for leaving the nauseous horror strictly alone.
Gerry's clinical instinct, however, prompted her to turn it over with her foot. About a fourth of the way along the under side were six short legs, arranged with no particular symmetry, just stuck here and there. Sprouting about the front end of the thing was a forest of what looked like dead gloved fingers-sensory organs of some kind. The mouth parts resembled a funnel, much like the proboscis of the common house-fly. Two eyes set on either side of the head were glazed in death. While the entire lower half of the abdomen was slit wide open; inside was nothing but a sickening mess of half-devoured vitals.
At that moment Tommy Strike finally galloped up, spluttering.
"Gerry! How the dickens did you ever manage to get here? And why? And —"
"Never mind all that!" interrupted Gerry. "Duval here brought me from Ganymede by rocket. He's the greatest pilot in the System. And I came because the paralysis ray equipment you have is no good."
"No kidding!" Strike was bitterly sarcastic. "You came a long ways just to tell us that. We found it out a few hours ago. It cost us two lives. Leeds and Machen are gone, burned to cinders."
"Burned!" Gerry rocked back on her heels, stunned at the
loss. "Then this-this Cacus really does breathe fire?"
"And how it does! You've never seen anything like it. But what I want to know is about the ray apparatus. What — '
Gerry quickly explained about Trevelyan's treachery. "I have the genuine article with me now." She displayed Lunde's other model.
Strike seized it avidly.
"Then let me have it! Will we give that monkey what-for!"
"But wait a minute, Tommy. What about this thing here?" She kicked at the empty dead thing at their feet. "Is this the Cacus?"
"Well, it was the Cacus." Strike looked a bit befuddled. "Though now the Cacus has helped itself to The Ark. Just walked in and took over. The pilot-house and engine rooms are locked, keeping it out of there, but the boys trapped in the nose of the ship are jettisoning the valuable stuff in case the Cacus decides to burn its way in there." He swore. "It's a mess!"
Gerry shook her head.
"Then you mean there's more than one Cacus; you killed this one, but another showed up. That it?"
"No, that isn't it! There's only one Cacus. It — it — " Strike stopped and drew a deep breath. He rolled the carcass over on its side and began again. "See that heat-ray burn? Well, here's what happened. When we found the paralysis apparatus on the blink, we were practically here already, so we figured we'd take this freak with our regular equipment. We found it crawling around with little jets of fire occasionally licking out of its mouth or snout or whatever it is. It was burning this mossy junk that grows all over, and also toasting plenty of these snaillike things, and then siphoning them up. Omnivorous.
"Well, the job looked like a cinch, so I creased it across the spine with a heat-ray, just enough to double it up while we doped out a muzzle to cap that fiery mouth. It twisted into a knot, all right, but then the damnedest thing happened. The thing split down the middle like an over-ripe fruit and another Cacus popped out almost full-born. The new one spouted a terrific blast of fire at us, and while we ducked out of range, the new Cacus just sat down and made a meal off its mother's — or is it its father's-insides. You could see the creature grow by inches till it got about the size of the original. Then it made for the ship.
"Leeds and Machen were guarding the air-lock, and they gave the second Cacus full-power heat-ray. It never bothered the thing. It just burned the two of 'em to so much charcoal with a single breath and pushed on inside the ship." Strike's mouth twisted bitterly at the memory. "Most of the gang escaped, though a few are still in there, safe behind the emergency bulkheads and with some of the air still preserved. Don't think anyone else was hurt."
The trio hurried toward The Ark.
"So the Cacus is bisexuals" said Gerry wonderingly. "Self-fertilizing. That's amazing. And only one of them on the whole satellite! That's really amazing."
Strike looked at her queerly.
"You don't grasp the truly amazing part of it-the Cacus' imperviousness to Leeds' and Machen's heat guns. Don't you see, Gerry? When Cacus number one was attacked by the heatray, it promptly transferred all its life and intelligence to the youngster in its womb. But it also transferred the power of unbelievable adaptability, so when Cacus number two was born it was completely defended against that heat-ray forever henceforth.
"It'd be the same for any other weapon we have for capturing an animal alive; it would simply let itself be born again fully adapted and protected. The only way we can stop this monstrosity is by suspending instantly all its vital functions, or by killing it outright."
Gerry thought for a moment. "Well, why worry?" she said finally. "A cathode gun will always do the trick."
"That's just it," said Strike with melancholy triumph. "The door to the arsenal was open when the Cacus entered the ship. Everyone ran out of there in a hurry, and there isn't a cathode gun in the crowd."
Gerry snorted.
"You certainly have a genius for getting into trouble. But it can't be as bad as you say. For one thing, this business about instant adaptability is so much moon-truffle. It's fantastic. Leeds' and Machen's guns simply failed. Or maybe they shot wildly."
Strike expressed unutterable scorn. Gerry Carlyle's crew were all sharpshooters, and they simply never got rattled.
"You'll soon see for yourself," was all he said.
When the three of them approached The Ark, the crew gave a ragged cheer for their famous leader and rallied hopefully around, visibly heartened. Nothing in their experience had ever completely baffled Gerry Carlyle, except the strange case of the Venusian murri, and they had confidence she would get them out of this predicament.
Gerry looked over the familiar faces with relief-Kranz, Barrows, Michaels-most of her veterans were all right.
"Let's find out about this adaptability stuff first of all," she decided. "Anyone got a hypo rifle handy?"
The original hunting party had carried several, and presently one of them cautiously approached the open port of The Ark to act as decoy while Gerry stood within easy range, rifle ready. The decoy peered gingerly inside the ship, passed the two grim chunks of seared flesh and fabric that marked the pyres of two brave men, then finally vanished inside. Minutes dragged by. Then a faint shout rang in the watchers' helmets, and suddenly the man tore out of The Ark as fast as be could run.
Once outside, he gave a tremendous upward leap many feet high, and just cleared a sizzling tongue of hot flame that belched out of the door behind him.
The Cacus, bulgy-eyed and hot-breathed, crouched angrily at the door.
Quickly Gerry drove home three hypodermic bullets in the creature's soft flesh in the crevices between the armor-like coverings. They took quick effect. The Cacus' head drooped sleepily, and it moved uncertainly as if undecided whether to come out or stay in.
Then suddenly a series of hideous abdominal convulsions wracked the thing.
The monster rolled over, still inside the ship; as if an invisible surgeon slit the Cacus open for two-thirds its length, the abdomen parted. Like some strange phoenix of terror, a new Cacus struggled out of the dying body of the old, stood defiantly with the upper half of its body raised on the six legs.
Unerringly and with no sign of nerves, Gerry deliberately emptied the hypodermic rifle into the new Cacus. The creature lowered itself to the metal floor, hunching along like a caterpillar. Then it turned and commenced ravenously to devour the soft inner parts of its host's anatomy.
Jerkily it seemed to increase in size, like a speeded-up motion picture of subaqueous life.
The hypo slugs had absolutely no effect upon it.
Petulantly Gerry slammed the rifle to the ground, where it bounced lightly.
"That's impossible!" she cried. "I've never heard of such a thing before in the entire Solar System!"
"Maybe it got here from some other solar system," Tommy said. "Lord knows how, and isn't native here. But that won't help subduing it."
"Rats! How about anesthetic gas? Any bombs available?"
A dozen were turned up. The Cacus having disappeared from view, Kranz daringly ran up to The Ark, threw several of the bombs in, and shoved the port partly closed. In less than five minutes the port was nudged wide open again, and the Cacus, ugly and flame-wrapped, glared challengingly at the little group of scattered humans. Everyone saw instantly that the new Cacus was slightly smaller than the one before, and was still growing. The amazing re-birth had defeated the anesthetic gas as well.
"Well," said Gerry cheerfully, "I guess we'll just have to quit playing games."
Chapter XIII.
Duval the Magnificent
She quickly set up Lunde's model paralysis ray machine. It worked successfully on Kranz, to everyone's amusement, and Gerry advanced on The Ark. Instantly the Cacus, watchfully guarding the port, emitted a tremendous streamer of fire close to the ground, curling up at the end like an enormous prehensile tongue. Gerry marked the limit of that flame and stopped outside it. Aiming the paralysis ray at the Cacus, she flipped the activating switch.
Nothing happened. Gerry fiddled
with the lens to no avail. She moved closer, only to be forced to scamper out of range of the breath of fire. Then she remembered. Lunde had told her this was a small-scale model, with less than half the power of the working model. The Cacus out-ranged them; they couldn't get close enough to allow the smaller ray machine to take effect.
The Cacus blew another fiery lance at the crew, as if in derision, then turned at some vibration within the ship and moved into its depths. Abandoning its sluggish mode of crawling, the Cacus coiled and raised its tail over its back much in the manner of the scorpion, and trotted off on its six curious legs in search of some incautious engineer who was seeking, perhaps, to sneak out to safety.
Gerry wore a baffled expression.
"That," she pronounced, "beats me. It looks like stalemate."
"Pardon, mademoiselle. Not stalemate." Everyone turned to look at Duval, who had been completely forgotten in the excitement.
"No?" said Strike. "Then it's a pretty good imitation of stalemate. He can't catch us in the open; we can't do anything to him."
"But, monsieur, every second that passes works in favor of the enemy. Our oxygen supply grows short. It is a situation of the most desperate. I, Duval, say it."
Immediately, though no one had noticed the mustiness of their air before, every person there gestured toward his throat and fumbled quickly with the oxygen valves. Breathing became consciously shallow, slow. There was no sign of panic among these veterans, but uneasiness was a definite presence among them.
Gerry bit her lip. "Any suggestions, Duval? You've played aces every trick so far."
"Merci bien. Yes, mademoiselle, I have the suggestion to offer. To combat our enemy, it is necessary that we study him, find his points vulnerable, if such he has."
"And how'll you get that monstrosity under your microscope?"
Duval's teeth flashed. "Ah. To study the present Monsieur Cacus, that is not possible. But his ancestors-eh?"
Startled looks were exchanged.
"Say, that's a thought!" Strike cried, and led a rapid trek across the plain to where the carcass of the first Cacus lay disemboweled. While not scientists in the strict sense, all the Carlyle crew had had scientific education and training. Almost at once a remarkable discovery was made by Kranz.
