After what seemed countless ages, the Venerians left him alone. Under the powerful effects of their cures, Parkinson began to recover. Hope welled up in his heart; perhaps the terrible experiments were ended.
When he was almost certain that the torture was over, his hopes were suddenly destroyed. The three Venerians approached again, each bearing a number of vessels containing germ cultures. These they placed on the table at Parkinson's side; then two of them withdrew, leaving the leader to continue his work. Uttering a few words in the Venerian tongue, he occupied himself with something on the table, and a moment later turned toward the bacteriologist, a long needle in his hands.
Parkinson felt a great burning pain in his left arm, as though a searing, hot needle had been thrust into his flesh. In a moment this vanished. Then a feeling of irresistible lassitude overwhelmed him; an unbearable weariness filled him with longing for rest, peace – death. This, too, was of short duration.
With the passing of the weariness, Parkinson became aware of a sharp throbbing in his arm. Rapidly this increased in violence, until suddenly an unbearable, excruciating agony seized him. Far greater was this than any pain he had suffered before. For a moment he struggled to scream, to move, to do anything to relieve his agony. There seemed to be a sudden snap – a cry of anguish burst from his lips – and his senses left him. Just as the bonds of paralysis had broken, he had lost consciousness.
Life returned to Parkinson very slowly. In a daze he stared around, uncomprehending. Then suddenly he realized that he was no longer paralyzed: nor was he in the operating room. The bed on which he lay was soft, comfortable; the room, unfamiliar. But not for long did his mind dwell upon this; in a few moments his eyelids closed, and he slept the sleep of complete mental and physical exhaustion.
Daring the weeks that followed, Parkinson did little other than sleep. Occasionally he arose, either to stretch himself, or to secure food, but for the greater part of the time he remained in bed. His body was a mere shadow of its former self as the result of his terrible experience on the white slab: his incessant sleeping, necessary because of his weakened condition, served to bring him back to his former health. The Venerians seemed glad to have it thus: asleep, he did not disturb their activities.

When he had awakened from his first period of natural slumber, he had received a terrible shock. His left arm was gone, amputated at the shoulder. Strangely, the wound had healed while he slept, probably the result of the Venerian doctoring, so there was no pain: but the shock had been terrible.
After he had recovered from the effects of that shock, he had resolved to make the Venerians pay for what they had done. And then he had realized that the inhuman brutes must be destroyed for a greater reason: unless he interfered, he believed that they would carry out their intention of destroying all human life.
As the weeks passed by, while strength was returning to Parkinson, he learned in a general way what the invaders were doing. They were engaged in developing vast quantities of microbes to be spread over Earth. When these were ready, a great amount of fine dust that the Venerians had brought with them, was impregnated with the bacilli. This was then taken up into the tower, where, as Parkinson learned later, it was blown out through the four tubes that spun around the tower's top, to drift through the air – to enter human bodies – to destroy life.
The Venerians worked with the cultures and impregnated dust without protection of any sort: evidently they were immune to the disease. Later Parkinson learned that he was likewise immune; they had rendered him so after trying the germs upon him.
Gradually the bacteriologist's health returned – so gradually that his captors seemed not to notice it. He was glad of this, for their vigilance had relaxed, and he did not want it renewed. Even when he was as strong and well as ever, he spent much time in bed, shamming illness. And when he could do so without danger of detection, he kept a close watch upon the three, waiting for a time when he would be entirely alone.

At last his opportunity came. The three Venerians rose to the surface together, leaving him in his room, to all outward appearances, asleep. But sleep was far from him at that moment; he had been watching.
Shortly after the sphere had vanished up the shaft, Parkinson emerged from his room. For a moment he surveyed the circle of doors: then he shrugged his shoulders. They all looked alike to him. Quickly he crossed the room, and pressed a button that mechanically opened a door. It was his purpose, first of all, to secure a weapon; one room would do as well as another for a beginning.
At first glance Parkinson was struck by the strange familiarity of this chamber: then, after a moment, he recognized it. A tall, high-backed metal chair in its center was its mark of identification. This was the chamber wherein the Venerians had transferred a record of his knowledge to their minds.
Carefully he looked around in search of a weapon, but the room held nothing but the chair and the thought transference device. In a moment he withdrew, closing the door behind him.
In the next room he entered, he was fortunate. This chamber was filled with strange devices of various kinds. While curiously inspecting the intricate machines, he saw something that brought a smile of satisfaction to his lips.
Against one wall stood a tall, glass case, one of the shelves of which held several metal devices that Parkinson immediately recognized as being the Venerians' weapons. Poignantly he remembered how a similar device had destroyed a ship.
Leaving the door slightly ajar, he crossed to the case and secured one of the weapons. For a moment he studied it. There was nothing complex about the mechanism; a cursory examination sufficed to reveal how it was operated. Pressure on a little knob at the back of the handle released the devastating ray.
He was about to slip the device into his pocket when he stiffened involuntarily. There was a sound of movement outside the room – he heard a step on the metal floor – then he whirled.
_______________________
One of the Venerians stood in the doorway, a menacing frown on his face. He was crouching, ready to spring upon Parkinson.
Quick as thought, the bacteriologist leveled his newly-acquired weapon, and pressed on the knob. There was a sudden spurt of flame from the Venerian's body; then it crumpled, sagging, shrinking together.
Hastily Parkinson released the pressure on the little knob, aghast at the destructive power of his little weapon. Then, as he remembered the torture he had endured at their hands, he directed the ray upon the ashes, until they, too, were consumed, leaving naught but a dark patch on the floor.
For several minutes Parkinson stood there in deep thought. There was no immediate danger from the two remaining Venerians, for they were up in the tower, while the sphere was in the meteor; so he could think with utmost safety. Deep thought and careful planning were necessary now, for he had taken the step that must mean either his death or the death of the Venerians.
Suddenly he leaped into action; he had decided upon his next move. Crossing to the case he secured another weapon. He wasn't sure that they could be effectively discharged without re-loading; handicapped as he was with one arm gone, he had to be certain of the reliability of his means of defense. Then he left the room, and crossed to the huge thoque sphere.
It was the work of a moment to enter this, and prepare to ascend. This done, he turned his attention to the numerous knobs on the wall. He had not seen them for quite a while; it was with difficulty that he recalled which knobs controlled the car's ascent. At last, hesitantly, but correctly, he pressed on the knobs, and the sphere rose slowly toward the surface.
At the proper moment, Parkinson, brought the vehicle to a halt, and slid back the door. Furtively he peered around. The Venerians were on the other side of the tower. Quickly he lowered the ladder and descended.
_______________________
As he stepped to the floor, a sudden cry of dismay fell upon his ears. One of the Venerians, coming around the car, had discovered him. Without a moment's hesitation, Parkinson aimed his little weapon, and pressed upon the knob. Like his fellow, the Venerian fell to the floor, a heap of charred ashes.
With the second Venerian destroyed, Parkinson dashed around the sphere, metal cylinder held in readiness. The leader of the Venerians was stealing stealthily around the other side of the car, his hand fumbling beneath his garment.
"Stop!" Parkinson cried. "Raise your hands above your head – empty!" A cylinder clattered to the metal floor as the Venerian's hands moved skyward.
"Keep your back turned!" Parkinson snapped as the invader began about. "I won't hesitate to press on this little knob, at your first hostile move! I'd thoroughly enjoy burning you to a crisp, so be very careful."
While talking, Parkinson had moved slowly toward the man from Venus; now, almost upon him, he quickly dropped his weapon into a pocket, and swung a terrible blow at the base of his skull. The Venerian fell to the floor without a groan, unconscious.
Parkinson stared at the recumbent figure rather dubiously for a moment. If only he had his other arm! But it was gone; with an impatient shake of his head he stooped and raised the senseless invader.
It was anything but an easy task for the bacteriologist to carry his seven-foot burden up the ladder and into the sphere, but finally, he succeeded in doing so. Then, without delay, he lowered the car into the meteor again.
As he bore the Venerian from the vehicle, he tried to decide upon his next move. Obviously, he had to secure the one surviving invader, so that he would not be a menace to Parkinson when he revived. And then the logical thing to do would be, in some way, to secure information from him as to how to cure the disease that was spreading over the world.
_______________________
The logical thing to do, yes – but how? With only one arm, the simple task of binding the Venerian presented considerable difficulty. How much more difficult would it be to force anything from him?
Then the solution of the first problem presented itself to Parkinson. What was to prevent his strapping this being into the high-backed chair to which he had been secured some time before? Quickly he crossed the circular room to the door he had first passed through while searching for a weapon.
Ten minutes later, when the Venerian regained his senses, he was fastened securely to the tall, metal chair.
"Well," Parkinson addressed him, "conditions seem to be reversed now, and you're the underdog. I've nipped your invasion in the bud. All your elaborate preparations are wasted."
Something resembling a sneer wreathed the Venerian's thin lips; a mocking gleam lit his cold, blue eyes.
"So our efforts have been wasted, have they? I'm afraid I can't agree with you. Already, enough bacteria have been released to destroy all life, though it will take longer than we desire. Even though you kill me, our goal will still be reached. The human race will die!"
A cloud of gloom fell upon Parkinson. He had expected this; but he had been hoping that he was wrong.
"Then there's only one thing for me to do, and that is: I'll have to force you to tell me how to undo the damage you've done."
The Venerian smiled mirthlessly. "You have absolutely no chance of accomplishing that," he said. "We've done our work too well to allow any interference now.
"You do not know this, but we have released upon your world the worst malady ever known to Venus. There is only one remedy; and I'm the only one who knows it, or who has the means wherewith to accomplish it. And I certainly won't tell!"
The worried expression on Parkinson's face increased in intensity. There was something in the Venerian's voice that convinced him that he meant what he said.
