And the glow grew.
And suddenly the hissing of the exploding rocket fuel began to diminish in volume. The apex of the flight was nearly at hand then.
And the glow around Gaddon began to color. From a weird phosphorescent whiteness it changed to a dull but intense yellow. And with the change, a strange feeling crept through his body.
It tugged at him with invisible hands. It played upon his every nerve, his every fiber, the innermost feelings of his sensibility. It grew stronger, this alien probing within him, grew as the glow pulsed in the chamber around him.
And suddenly, instead of a fierce feeling of triumph, a sense of dread swept through him. He fought at the gripping sensations within him, tried to dispel them, to no avail. They grew stronger, like invisible hands that were changing the very essence of life inside him.
And as the thought passed through his suddenly tortured mind, he realized that was exactly what was taking place. A change. A change beyond his comprehension, beyond the understanding of any man. Beyond-- And the whining fearful mew of the cat beside him changed. It tensed against his body, and the whine in its animal throat became an irate hiss. He looked down and saw the hackles rising on the back of the cat, saw the creature looking up at him now, not with wide frightened eyes of appeal, but with a ferocity of wildness that brought a chill to his inner being.
And the glow grew around him, brilliant yellow in texture now. And with the increasing brilliance of the light, the feeling of change grew within him.
It was stronger than he now. It held his every heartbeat in its pulsing grip. It throbbed in his temples, ached to the ends of his toes, set his body aflame with it.
And the cat suddenly lunged against him, its sharpened claws biting through his garments and into his flesh.
His hands reached down in a quick movement and gripped the body of the cat. He tore the raking claws away from his body and held the cat in the air beside him.
The creature writhed in his grasp, fighting madly to escape. And as his grip tightened on the animal, the eyes of the cat suddenly locked with his.
He felt the forces within him reach a crescendo at that moment. And his body was frozen immobile, his eyes locked on the cat's eyes, burning into the animal, the animal burning into him. Burning and burning ...
It could only have been a matter of seconds, he knew. But they were seconds that stretched into the farthermost reaches of eternity. Seconds that lived a million years and passed in another fleeting instant.
And then he could move again.
And he felt strange as he moved. It was as if he was another person, as if the body he moved was alien to him, as if it had never belonged to him, to any man, to any thing.
And his eyes tore away from the now dulled expression in the cat's eyes. He did not find it strange that this was so. He knew in some inner sense that the mighty life force in him had quelled the cat. Had stilled the fighting in its feline eyes.
And he saw his hands clutching the body of the cat.
He stared at them for a long disbelieving moment. For they were not the hands he had known. They were not the hands of Blair Gaddon. They were not the hands of any man. They were long and tapered and claw-like. There was dark fuzzy fur around them, fur that was cat-like.
Deep within him a fear struggled upward through his mind. A cold dread that forced his lips to move, to utter a gasp of the terror he felt.
And the sound left his lips.
It left his lips and echoed terribly in his ears. A harsh sound. A mewing sound. A cat sound ...
The creature in his grasp struggled feebly then. It was a small movement, a movement without vitality, almost without life. And as the creature moved, a sense of rage welled up inside him. A rage that he could not control, an anger that he wanted to unleash to its fullest. And as it took possession of him, the human part of his mind shrieked and forced words from his lips.
"You fiend! You fiend of hell!"
And his fingers crept up to the neck of the cat and closed in a mighty grip. He felt the animal give a single desperate effort in his grasp, but his grip tightened and he saw the mouth of the creature open wide and heard a faint hissing gasp as its tongue stuck far out and its eyes bulged in a last moment of life.
Then the animal lay limp in his claw-like hands and he dropped it to the floor of the rocket chamber, a growl of frustration leaving his lips.
He stared at the cat's body for a moment, then his fingers stole up and touched his face. He felt the hairy coarseness of it, the furry tingle of his once smooth skin. And he screamed into the now fading glow that he knew was the energy of the cosmic rays.
"No! No! It can't be true! I haven't changed like this! I--I--meowrr ..."
Around him the thunder of the rocket fuel suddenly vanished into silence, and then the rocket gave a lurch.
Deep within his mind he knew that the instrument section had been released from the main body of the projectile, and even now he knew the sealed chamber was falling back toward the earth, back toward the atmosphere where the parachute would take hold and drift the chamber safely down to the Arizona soil.
And a dread closed over him in that moment. Back to the men. Back to the things of men. Back he must go, a mewing thing that was not a man. A thing that he felt was taking hold of him, driving the last vestige of human instinct from him.
He fought it. He fought it mewing on the floor of the rocket chamber.
"He must have gone mad!"
Fred Trent pulled his gaze from the sky and looked with stunned eyes at the figure of Dr. Mathieson standing beside him. The scientist was trembling with an inner feeling, and his head was shaking in disbelief.
"Gaddon! The man is going to his death! It's insane!"
Again Mathieson's voice broke the silence in the huddled group of men. Then the newspapermen came to life and excited talk became a jabber of words around them. Trent took the arm of Mathieson and turned him. He tried to lead the scientist away from the newspapermen but one of them stepped forward and grabbed his arm.
"But why did he do it, doctor? The man must have had a reason!"
Mathieson shook his head numbly.
"I--I don't know, unless ..." his voice trailed off for a moment and then he spoke again. "Unless he really believed what he said ..."
"What did he say, doctor?" the newsman asked.
There was a puzzled note to Mathieson's voice as he answered.
"He disagreed with me on the supposed effects of the cosmic rays. It has been my contention that they are of lethal effect, and Gaddon maintained that I was wrong. He kept insisting that they were a source of life energy. That was why we decided to experiment with an animal--to see what effect the rays would have on a living creature ...
"But this! I never dreamed of such a possibility--to prove his point he signed his own death warrant!"
"That's a story, doctor, a real story!"
Trent heard the newsman exclaim excitedly. And then it came to him that the real story was as yet untold. The real story that had been unfolded in his car earlier that day.
Fred moved suddenly away from the clamor of the newsmen around the scientist. He knew what he had to do.
He hurried across the ground to his waiting coupe outside the Administration building. Then he got behind the wheel and started the motor.
He drove to the gate and waited until the guard passed him through, then he turned up the road toward Tucson.
As he drove he felt an odd tenseness sweep through him. For he was thinking of what Gaddon had said on the drive up to the Proving Grounds. He was remembering the man's words on the cosmic rays and the secret of eternal life they held. And Fred Trent knew that this was the biggest story. The story that he alone held. It was the big break that he had been waiting for. It would be his exclusive. The inside, personal story of a man who had died to prove his theory. Told as Gaddon himself had related it. With all the vanity of the man, all the pompous assurance he had shown. It would make the headlines and feature sections all over the country. The story of a man who had flown to his death in quest of immortality.
And then Trent's thoughts grew sober suddenly. But was he going to his death? Could he be sure that Mathieson was right? That Gaddon was suffering from some streak of insanity that had manifested itself in this final venture of madness? Or could it be that Gaddon might be right, that ...
Trent set his lips and sighed. No, that couldn't be true. It was beyond the comprehension of man.
What mattered now was the story. The story that would put his name in a thousand papers all over the country. And he thought in that moment of Joan Drake. A warm smile pulled at his lips as he thought of her. This would force her to quit her job now and marry him. The one condition she had made--he had finally overcome.
He thought of the date he was supposed to have with her that evening. It would have to be postponed until later. The story came first. And then ...
He drove his car swiftly through the outskirts of the city and into the main part of town. Then he pulled up before the offices of the Tucson Star and left his car at the curb.
He entered the building, took the elevator to his floor and walked into the city room. The clatter of typewriters met his ears and the sound was sweet to him in that moment.
He crossed swiftly to his desk and sat dawn. Then he motioned to a copy boy. The boy came up to his desk.
"Jerry, tell the chief to hold up the form on page one. I've got a special--an accident out at the Proving Grounds. Headline copy."
The youth hurried away toward the office of the City Editor, and Fred picked up his phone and dialed a number. He waited a moment and then the voice of Joan Drake came across the wire.
"Dr. Fenwick's office."
"Joan, this is Fred."
The girl's voice laughed across the wire. "Don't tell me you're planning to break our date? Just when I get all dressed up."
A smile crossed Trent's lips. "You're almost psychic, honey. Fact is, I was calling to tell you I'll be a little late."
There was a pause and when the girl spoke again there was an injured note in her voice.
"Well, that's a fine thing. I wait here deliberately after hours for you to pick me up and now you tell me you'll be late! Just what's so more important than me right now?"
"I haven't got time to tell you now, Joan, but believe me, I've got the break of the year. A story that will rock the front pages across the country. I'll tell you all about it later. You can wait at Fenwick's place. He won't mind, will he?"
He could hear the girl sniff on the other end of the wire.
"I don't suppose he will, but I don't think I can say the same for myself."
"That's a good girl," Trent laughed. "Just wait for me. It may be an hour or so--"
"An hour or so! What are you writing, the great American novel?"
He looked up and saw the frowning face of the City Editor approaching his desk. He spoke hurriedly.
"I've got to sign off now. The boss is coming up. I'll see you later. Give my regards to Brutus."
He replaced the phone as the editor reached his desk.
"What's all this about a remake on the front page, Trent?"
Fred nodded. "That's right, chief. The biggest story since the atom bomb. Listen!"
He gave a short account of what had happened, and then added the personal details of his talk with Gaddon. He saw the eyes of the editor widen as he went on, and by the time he had finished, there was a look of excitement on the editor's face.
"Get to that story, Trent. Write it hot, and write it fast. I'll hold the first form and tear down the front page. Stress the human interest angle. Play it up big. We'll hit the news wires with it after we go to press."
Then a smile crossed the editor's face. "And you'll get a by-line on this, Trent, that ought to put you in for some big money. Nice work."
Then he turned on his heel and was hurrying across the city room toward his glassed-in office, hollering for a copy boy as he went.
Trent turned back to his desk and slipped a sheet of paper into his typewriter. There was a tenseness around his eyes as he brought his fingers down on the keys. For a moment the old questions rose again in his mind. Was Gaddon right? Could it be possible that ...
Then he forgot everything but the story. And his fingers clicked against the keys, putting it down on paper.
The rocket chamber swayed gently through the night air, whistling its way slowly downward, moving more slowly as the great parachute above it caught in the rapidly thickening density of the cabin's atmosphere.
Inside it, the thing that had been Gaddon, the thing that was no longer a man, sat on the floor of the chamber, idly toying with the dead body of the cat.
Strange thoughts coursed through the mind inside its head. Half of the mind that belonged to Gaddon, and half of the mind that was an alien thing, a creature unnamed.
There was a thought of killing and the thought was good. The claw-like hands played with the cat's dead body, fondling it idly, wishing it were still alive so that it might die again.
And the other part of its mind, the part that still knew it was Gaddon, rebelled against the thought. Tried to drive it away. Tried to move that alien intelligence into the rear of his consciousness.
A growl left his lips as he struggled with it. And then a whimpering sound.
For now the alien thought of killing and the joy it had experienced as the cat died scant moments before, was replaced by another thought. A thought of loneliness.
It was a weird feeling, an utter loneliness that came from the great void beyond man's planet. It cried out in silent protest for it knew it was alone in this world of men.
And it knew it would remain alone, friendless. For what manner of men such as the other part of its mind showed would react in a friendly fashion? Where would be their common meeting ground? There could only be one, it knew. And that one was fear. Fear and the hate that went with it.
A growl left its lips again, and Gaddon's thoughts tried to force their way through. Tried and failed again.
But was it necessary to want companionship? It thought about that for a moment. And then the alien beast thoughts grew sharper, clearer. It knew suddenly that it did not want man's compassion. It knew that there was only one driving thought in it. Hate. Hate that would inspire fear. Fear that would freeze its victim into terror. And terror that would be replaced by death. And then it would be happy again. Happy to sit and fondle the thing that had been alive. And it knew something else. It knew that a hunger would have to be satisfied. A hunger that called for flesh.
Deep, primeval thoughts raced through it then. Thoughts that were spawned in the ancient jungles of a new and steaming world. A world where great cats roamed, where screams of cat-rage split the air as tawny bodies arced in lightning leaps to land on the trembling bodies of their victims. It was a satisfying thought. A thought that spanned the ages of Earth, a sense that was inherent in all cat minds through the ages.
And as the thought raced through that portion of its mind, the part that was Gaddon struggled to fight it back. For it realized with a sickness that spread horror through it that the thought was part of the animal existence that had been created in him. Part of the monster that lay by instinct in all feline creatures. And Gaddon knew that the dead creature at his feet, the limp and twisted body of the cat, had died long before his hands had crushed it in their mighty grip. For the essence of that life, that animal existence, had been merged with him, fused by a mighty source from outer space.
And as he struggled with the thought, fought to regain the balance of control of the strange body that was now his, the rocket chamber swayed in a gust of wind from without. And as he clutched the sides of the chamber with his strong claw-like hands, the chamber gave a bounding lurch as it struck the ground a glancing blow.
There was a grating sound as the metal chamber gouged into the earth, sank its weight upon the Arizona soil. And the thing was thrown violently against the side of the chamber.
Then there was quiet again.
