CHAPTER 1

..................

ROBERT ELLSMORE GRANDON STIFLED A yawn with difficulty as the curtain went down on the first act of Don Giovanni and wondered what was the matter. It wasn’t that opera bored him, or that tonight’s performance was inferior; in fact, what he had been able to give his attention to struck him as being among the best performances he had seen. But something was distracting him, something he could not put his finger on; and the effort to keep his attention on the music and the performers was tiring him. Perhaps it was just one of those days, he thought.

He was tired of life at twenty-four, he, decided—tired and disillusioned and somehow trapped. After his spell of military service, he’d broken away from family obligations and expectations to join revolutionaries in Cuba. The struggle there had seemed important, worth risking his neck for; but he’d seen, much earlier than some others, that the new regime was just a change of masters. He’d gotten out while getting out was easy and returned to take up the career in, insurance administration that his uncle wanted him to take —the uncle who had paid his college expenses. Now, Robert and Vincent Grandon would prepare for the position that. Uncle Arthur would be leaving in a few years. It would be a good career for both young men; for while only one could step into Arthur Grandon’s shoes, the second spot would be no less desirable.

Very likely, with full effort, he could make the top—but his cousin had the extra measure of devotion to the business that Robert Grandon simply couldn’t bring. Robert Ellsmore Grandon yearned for action, adventure, romance—something that seemed to be gone in this world of the Twentieth Century.

He made his way to the bar thinking that he’d chuck it all in a moment for a chance to think and act for himself, for a chance to accomplish something worth while according to his own lights. Yes—insurance was worthwhile, he thought as he sat at the bar and beckoned to Louis, but not worth his while.

Louis looked his way, nodded, and started to mix a Gibson for him. The bartender had a curious grin on his face as he set the glass down. “Did you get the message, Mr. Grandon?”

Robert Grandon blinked. “What message?”

“Didn’t you see the papers today?”

Grandon shook his head. “Just glanced at them. What’s up?”

Louis went back and bent down, to return with the Times, folded to a certain page, and placed it on the bar before him. To Grandon’s astonishment, he saw a sketch of himself staring him in the face.

“Had you planned in advance to come tonight, Mr. Grandon?”

Grandon looked up with a puzzled expression on his face. “No—now that you mention it, I hadn’t. I was going to ask a friend to come with me next Friday night. Came down this morning to see about tickets, and decided that I’d come tonight alone, when I found that there was a good seat available...Don’t know why, now that I think of it.”

Louis’ face wore a strange smile. “Read that ad, Mr. Grandon. Maybe you are the one.”

Grandon picked up the paper. The heading read, “I Want You!” There was no caption under the sketch; beneath it, the text said: “I do not know your name, or anything about you, except that you are in the city. I want to perform an experiment, and you may be the man I need. If you are, you will know by these tokens.

“You will feel an urge to go to a certain place tonight which you may or may not have been planning to go to, and you will want to get there around 8 p.m. Starting at 8:30 p.m., every half hour, I will send you a message. You may not hear it the first or second time, but you may feel distracted. If you are the man I want, it will seem as if a voice is speaking to you. It will be a voice in your mind; it will say `Doctor Morgan’ and direct you to go to a particular spot. There a man will be waiting for you; he will ask you a question which I shall also tell you of when I communicate with you. Please give him a hearing before you decide.”

“Looks as if you’ve gotten the first part of it, Mr. Grandon. You hadn’t expected to come tonight, but here you are.”

Grandon put the newspaper down. It had been just about half an hour after the performance started that he’d begun to feel distracted and a little irritated.

Louis said, “It’s two minutes of nine, Mr. Grandon. Maybe you’ll get the message this time.”

Grandon sipped the Gibson, with his eyes on the clock. He tried to relax, to let himself open to whatever thoughts might come into his head. He’d heard of experiments in telepathy, and while he didn’t find parapsychology too convincing, he had no strong bias against it. In fact, he’d thought that it might be fascinating if this sort of thing could be so. Here would be a new frontier if...

It wasn’t exactly a whisper, but there was a softness about a voice he now seemed to hear yet not to hear. It said, “Doctor Morgan.” Grandon sat up straight. Again it came: “Doctor Morgan.” A third time; then the voice said, “Go to the telephone booths in the lobby. A man wearing a tuxedo with a green lapel pin will offer you a cigarette.”

The voice ceased. Grandon waited a moment or two, but there was nothing more.

“Did you get it, Mr. Grandon?” asked Louis eagerly.

Grandon finished his Gibson and put a bill down on the bar. “Could be,” he said. “I have a pretty good imagination, you know. Think I’ll wait another half hour and see.”

He left the bar. Either this was or it wasn’t. If it was, then he might as well follow up now as wait another half hour. If it wasn’t, it didn’t make any difference; he couldn’t possibly pay any attention to the opera now, no matter who was singing.

He made his way to the phone booths in the lobby and looked around, oblivious to the feminine eyes that turned to glance at his broad shoulders and curly black hair. No one fitting the description he’d received was in sight. He waited a moment and began to feel foolish.

Just imagination, he decided a little sadly. Well, there was time for a cigarette before he had to get back to his seat. He was reaching for his case when a pleasant voice at his right said, “Try one of mine, won’t you?”

Grandon turned and looked into the smiling eyes of a man about his own age. A man wearing a tuxedo with a green lapel pin. He accepted with thanks.

“Excellent performance, don’t you think?” volunteered the smiling one, lighting a cigarette himself which he had, unnoticed by Grandon in his confusion, taken from the side of the case opposite the one which he had extended a moment before.

“I suppose so—ah—why, yes, of course...”

Grandon was beginning to feel unaccountably drowsy.

Suddenly he slumped forward, and would have fallen on his face, but for the quick assistance of the friendly young man. A moment later he lost consciousness.

An attendant came running up. “What’s the matter with your friend?” he asked.

“Fainted dead away. It’s his heart; he’s had spells like this quite often lately. Help me get him outdoors.”

The two of them carried Grandon outside, followed by the more curious bystanders. When he reached the sidewalk, the young man waved to the driver of a car parked on the other side of the street. It immediately swung across and drew up to the curb.

“Let’s put him in the car,” said the young roan. “I’m used to this —a spin on Michigan Boulevard will revive him. Just needs fresh air. His doctor has told me how to handle him.”

They lifted Grandon into the car and the driver put the top down. The young man handed a crisp bill to the attendant and got into the car, which drove away.


CHAPTER 2

..................

WHEN GRANDON REGAINED CONSCIOUSNESS HE was lying on a cot in a dimly lighted room. He looked about him in bewilderment as he saw four bare concrete walls, a heavy oak door studded with many large bolts, and a small window fitted with powerful iron bars more than an inch in diameter.

There was a chair and a small table with a lamp on it next to the cot. On the table, Grandon saw a sheet of paper. He rolled over and picked it up, switching on the lamp.

“Dear Mr. Grandon,” he read, “I must admit and apologize for technically kidnapping you; but I hope to be able to persuade you shortly that this was both necessary and to your advantage. Now I must ask you to be patient for a little while; I shall see you soon. The drug you were given should be wearing off by evening—you were kidnapped last night—and I can assure you that it will have no harmful after-effects, physical or mental.” The paper was signed, “Dr. Morgan.”

Grandon arose and tottered unsteadily toward the door. It was evidently locked from the outside, for he could not rattle it. He went to the window and peered out. Night had fallen, and a myriad of twinkling stars looked down at him from a clear sky. Not a tree, house, or earthly object of any kind was visible. There was only the starry sky above and the black void below.

He heard the sound of talking, and wheeled about as a bolt slid back and the door opened. Two men entered. The foremost was tall and of large structure; his forehead was high and bulged outward, so that his shaggy eyebrows, which grew together above the bridge of his aquiline nose, half-concealed his eyes. He wore a painted, closely-cropped beard, in which a few gray hairs proclaimed him as middle-aged. Behind him was the young man who had given him the drugged cigarette in the lobby of the opera house.

The young man advanced and extended his hand. “How are you feeling now, Mr. Grandon?” he asked. “Ah, you seem surprised that we know your name. That will be explained to you. I should have introduced myself sooner. My name is Harry Thorne. Allow me to present Doctor Morgan.”

The big man held out his hand and said in a booming bass voice, “This is a pleasure I have long anticipated, Mr. Grandon.”

It was nothing like the voice he had heard in his mind, and yet it was the same voice. Grandon realized that at once; and his curiosity, added to the feeling of confidence in these men’s intentions toward him that the note had imparted, washed away any resentment he might feel at their methods. He clasped the doctor’s muscular hand and muttered an acknowledgment.

“And now,” said Morgan, “if you will accompany us to dinner, we shall start the explanation due you. Afterwards, I shall ask you to read two interesting manuscripts before we talk further; they will tell you far more, and prepare you far better, for the experiment I have in mind than a lecture from me.”

In Dr. Morgan’s drawing room, where night had given way to day while Robert Ellsmore Grandon read two novel-length manuscripts, Dr. Morgan— who had entered just as Grandon was finishing the last chapter of the second box of neatly-typed pages—smiled at his guest quizzically. “What do you think of them?” he asked.

Grandon shook his head. “If I hadn’t had the experience of the past day or so, I’d think they were just good stories and nothing more. Even so, they sound fantastic:

“They are,” Morgan agreed. “But nonetheless true. To summarize briefly, I started experimenting with telepathy ten years ago, and finally succeeded in building a device which would pick up and amplify thought waves.”

“And thought waves, you found,” said Grandon, “are not limited by space or time. So you picked up the waves projected by another man who had built a similar device to project them—only this man was on Mars.”

“But not the present-day Mars—the Mars of some millions of years ago, when a high human civilization did exist there.”

“And you and this Martian scientist, Lal Vak, found that persons who are nearly doubles in physical appearance may have similar brain-patterns— enough alike so that consciousness may be exchanged between them. Your first experiment involved such an exchange between an Earthman named Harry Thorne and a Martian named Borgen Takkor. The man you now call Harry Thorne was born on Mars as Borgen Takkor, while the true Harry Thorne is now living on Mars —and leading a most adventurous and satisfying career from the account I just read.”

Dr. Morgan nodded. “He and his princess have had many adventures together beyond those related in the first manuscript. To us, of course, both have been dead millions of years. But it is possible for me to tune in on their lives at any point where Harry was transmitting to me. He has never regretted his choice.”

“Then”, went on Grandon, “you got in touch with a Venusian named Vorn Vangal, who is a contemporary of Lal Vak and Borgen Takkor. With his help you constructed a space-time vehicle through which your nephew, Jerry Morgan, was able to go to Mars in the flesh. And he, too, made out pretty well.”

Morgan nodded. “Yes. I sent Jerry to Mars that way, and hoped that I’d be able to send someone to Venus the same way. But my telekinetic control failed in some way on the return trip, and I never recovered the ship I built for Jerry. Vorn Vangal said he would build one on Venus and send it to Earth for me, so that I could visit him, but I do not know when this will be possible. It may be soon; it may not be for some years.” Morgan smiled. “And I’m not too patient a man. I know that it is possible for me to get an account of Venus as seen by Earthmen’s eyes—the Venus that was, in relation to the Mars that was—just as I learned about Mars in those two manuscripts you’ve read. So I asked Vorn Vangal if he could send me the brain waves of two Venusians, to see if I could find their counterparts here on Earth. Then Harry urged me to try to see if there was a Venusian with whom he could change personalities—so I sent his picture and brain-wave pattern to Vorn Vangal.”

“I see. And Vorn Vangal sent you the picture and brainwave pattern of a Venusian who was—me.”

“Yes. You’ll recall that Lal Vak had shown one how to construct a mind- compass, which would indicate whether there were any living persons here on Earth whose brainwaves corresponded with those of the Martians whose pictures he sent me. This would not only aid in my finding such people here on Earth, it would also protect me from disappointment on coming across someone who looked right, but whose brain-pattern did not match closely enough for an exchange of personalities, after all.”

“Has that happened?” Grandon asked.

“Only once. But now it’s all arranged for Harry; and I hope you’ll be interested in going to Venus, too.”

Grandon smiled. “After reading those two accounts of conditions on Mars, I certainly am. Of course, I suppose it’s nothing like Venus.”

“There are differences, of course, but the civilizations are on a somewhat similar level. The planet is known as Zarovia, and your physical counterpart is a gentleman who has been enslaved by an Amazon ruler—a princess with no thought save of her own pleasure. He finds it impossible to escape from bondage, and is therefore willing to make the exchange. Mr. Thorne’s bodily duplicate is a prince of a realm on the opposite side of the planet from that occupied by the slave. The prince has been petted and pampered and shielded from all danger, and longs for adventure; he is willing to exchange bodies for a time with Mr. Thorne. Well, what do you say? Are you willing to make the trip?” Grandon smiled.

“You know, Doctor, I’m a little surprised. You investigated the Earth- born Harry Thorne very carefully, because you’d made a bad choice and sent a criminal to Mars ahead of him. You knew your nephew thoroughly because you were in telepathic communication with him for years though he didn’t know it then. But what do you know about me?”

“Touché!” chuckled Morgan. “I forgot to tell you. I’ve gone a good ways beyond telepathic projection in the last few years. When I contacted your mind, I also got a very full picture of your character and personality— no intimate details, but sufficient to assure me that you were the sort of man I wanted. And that you were very likely to go along with me if the way could be cleared for you...But suppose you tell me of any inhibiting factors; I think they can be cleared up.”

Robert Ellsmore Grandon recounted his personal situation briefly, and Morgan nodded. “Yes,” he said. “This checks with the information I’ve gathered on Mr. Arthur Grandon since you arrived here. He’s sincerely devoted to you, you know. I don’t believe he’ll stand in the way if he knows you want to go on some caper of your own and by your own choice. Suppose you phone him long distance now. Here’s what I suggest you tell him...”

“You were right, Doctor,” Grandon said after bidding his uncle farewell. “Uncle Arthur agrees that Vincent is better suited to handle the firm than I. He just wanted me to try for awhile and see—says he half expected something like this when I disappeared and was concerned lest I forget to let him know.”

“Then we need waste no more time, Mr. Grandon.”

“But—my body will remain here while my personality goes to Venus. What happens to it?”

“You need have no fear about that. The man who comes to inhabit it —forgotten about him, haven’t you?—will naturally be careful of it; for if he loses it there will be no return for him, either to this world or his own.”

“What do we have to do in order to exchange bodies? And how will you keep in touch with me?”

“I will, at regular intervals, establish telepathic rapport with you and Thorne while you are asleep. You will know nothing of these telepathic communications—which will be as detailed as those you read last night —unless I see fit to convey a message to you which will probably come in the form of a dream, so vivid that you will remember every detail. If you wish to communicate with me for any reason whatever, I will learn of it when I establish rapport with you.”

Grandon sighed. “I’m ready. Want me to lie down and look into a mirror the way Harry Thorne did when you sent him to Mars?”

“Right. And the present Harry Thorne will follow you in a few hours —you may meet on Venus, though it isn’t too likely.” He set up the mirror, painted with alternate circles of red and black, as Grandon reposed on the sofa. “Now think of Venus, far off in time and space—millions of miles, millions of years away...”


CHAPTER 3

..................

ROBERT ELLSMORE GRANDON, WAS AWAKENED from a sound sleep by a shaft of brilliant sunlight which shone through the mica-paneled window of the quarry- slaves’ sleeping quarters. He blinked, turned uneasily, then sat up. His muscles appeared stiff and bruised and his back smarted and burned. He noticed that his sole articles of apparel consisted of a scarlet breech-cloth and a pair of sandals of strange design. His skin was browned; his hands were rough and callused. His face was covered with a thick, black beard, and his hair was matted and unkempt.

He rose stiffly and walked to the window, hoping for a clear view of a Zarovian landscape, but he was disappointed, for in front of his window there stretched a solid wall of black marble cliffs. The only visible vegetation consisted of a few pink toadstool-like growths which grew from niches in the rock, some over twelve feet in height.

He turned and glanced at his room-mates. Fifty men were quartered in the sleeping shed. The bedding consisted of a coarse, dried moss, which made an exceptionally resilient couch. The men were attired like Grandon, except that their breech-clouts were gray instead of scarlet. Their skins were sun-burned like his own, and marked with scars and open wounds.

Grandon was startled by a hollow booming sound, and someone on the outside opened a large door at the center of the shed. Instantly every man sprang to his feet, and he saw that they were forming in single file to march through the door. He joined the procession, which was heading for a large building in the midst of a group of sheds similar to the one he had occupied, and saw that the sound emanated from a large cylinder of iron suspended from a steel beam in front of the building, and beaten by a man who wielded a large club wrapped with thongs.

Heavily-armed guards stood at intervals of about fifty feet on either side of their pathway. Each guard carried a tall spear with a broad blade about four feet long; a sword with a basket hilt, its blade rather like that of a scimitar, hung from the left side of the belt.

From the right depended a weapon which was utterly strange to Grandon. It was about two feet long, oblong like a carpenter’s level, and apparently composed of blued steel. A rivet passed completely through it about four inches from the end, holding it firmly to the belt, although it could be tilted at any angle, and its wearer could point it in any direction by turning his body.

Grandon had yet to learn the efficiency of this weapon, the tork, which fired needlelike glass projectiles filled with a potent poison that paralyzed man and beast alike almost as soon as it penetrated, and had a range as great as the most powerful of rifles. These tiny bullets were propelled by a highly explosive gas, ignited by an electric spark at the touch of a button.

The gas was compressed in a chamber at the rear of the tork, while the glass missiles were held in a magazine near the muzzle. After a shot was fired, the weapon would automatically reload, a bullet sliding into place in front while just the right charge of gas was released in the chamber behind it. Each tork, held a thousand rounds of ammunition.

The slaves passed through the building where each man had his ration doled out to him: a bowl of stewed mushrooms and a steaming cup of a beverage which Grandon found to be very much like a strong wine.

As he followed his companions, Grandon noticed that each man stopped before a small shrine and stood for a moment with head bowed low and hand extended toward it, palm downward. When he reached the shrine, he stopped as the others had done, then gave a gasp of amazement at a life-size painting of the most beautiful woman he had ever seen.

She wore a robe of scarlet, ornamented with gold and precious stones, and a jeweled band of platinum imprisoned a mass of golden curls which were piled on top of her head after a style different from anything he had ever seen. She was seated on a massive golden throne with cushions of scarlet, across the arms of which rested a scarbo—a sword like those carried by the guards, but with a hilt of gold studded with rubies.

Could this be the Amazon ruler of whom Dr. Morgan had spoken?

A sharp exclamation brought him to his senses; he turned and saw an overseer advancing with whip upraised. Quickly bowing as the others had done, he ran forward to join his fellow slaves.

Once outside the building, the men seated themselves on the ground in little scattered groups for their morning meal. Grandon joined a company of those who had occupied the same dormitory with him.

He could not take part in the general conversation because the language was unintelligible to him—yet the words sounded strangely familiar. A recollection of their meaning was stored in the brain cells of the body which had become his, but the ego, which was Grandon could not interpret them. He kept silent and listened.

The meal finished, the slaves were herded to the quarries by their drivers. Each driver, who had charge of ten slaves, wore both tork and scarbo in his belt and carried a whip, the five lashes of which were woven from some coarse fiber and interwoven with short pieces of a brittle, nettle-like moss, which broke off in the skin of the victim, inflicting pain like that of a thousand bee stings.

Grandon managed to keep pace with his fellow slaves. The intense heat of the sun would have made labor in the open impossible, had it not been constantly tempered by the floating clouds of vapor, ever present in the dense, moist Zarovian atmosphere.

The marble was being removed from the hillside in large rectangular blocks, by thousands of slaves working on a series of terraces, each of which was the height of one of the blocks. The crews were so distributed that the terraced hillside constantly retained the same general contour.

Grandon’s crew worked on the bottom terrace all morning, but were ordered to the top in the afternoon to reinforce the laborers in that section who, for some reason, had not kept up their quota. He and a fellow slave were removing one of the heavy blocks by means of levers when his end slipped and fell on another block, breaking off a large fragment. The driver raised his whip and struck Grandon a stinging blow across the shoulders.

Quickly wheeling, Grandon landed a tremendous right hook on the point of the man’s jaw. It was a clean knock-out. Another driver came running with whip upraised, but Grandon bowled him over with a marble fragment and ran through the group of startled slaves toward the brow of the hill. Some one raised the alarm and a half dozen torks were immediately pointed toward the fugitive. Several slaves fell, struck by the missiles intended for him, as he disappeared over the hilltop.

Before him stretched a dense, waving forest of tree ferns into which he plunged without slackening his speed, his pursuers close behind. As he dodged in and out among the tree trunks he could hear their halloos growing fainter and fainter; finally no sound was audible except the rustling of the countless, wind-shaken fern leaves.

He slackened his pace and, after proceeding about a mile, farther, stopped and looked about him.

Huge tree ferns with rough trunks and foliage growing out of the tops like that of palm trees, some of them over seventy feet in height, towered above the shorter, more bushy varieties which were themselves giants. Then there were climbing ferns hanging in tangled masses, creeping ferns and dwarf, low-growing kinds, barely raising their fronds above the thick carpet of moss which everywhere covered the forest floor.

Grandon noticed that the ground slanted slightly toward his right, and intuition told him that this might lead to a valley and water. He changed his course accordingly. He hoped also to find some fruits, berries or nuts with which to satisfy his hunger.

As he trudged wearily forward, sunset was succeeded by twilight, and before he realized it, the black, moonless Zarovian night had spread its impenetrable mantle about him.

Suddenly, from out the darkness behind him, came a peal of horrible, demoniac laughter.

As he wheeled, two glowing phosphorescent orbs were slowly advancing as if something were creeping or slinking toward him. Then, without warning, the hideous noise was repeated at his left.

He turned to face another pair of menacing eyes, then leaped for the trunk of the nearest tree-fern and climbed it barely in time to escape the snapping jaws that yawned beneath him.

Not until he had reached the leaf-crown, fifty feet above the ground, did he pause or look downward. Then he saw, not two, but a dozen pairs of eyes glancing toward him, while peal after peal of the nerve-racking laughter smote his ears.

Time dragged along. What manner of things were these? Evidently they were unable to climb, or they would have followed him ere this. The fact that they did not leave, even after several more hours had elapsed, made it evident that they expected to get him.

He had been hearing a peculiar crunching sound some time before he located it and guessed the terrible truth.

They were gnawing through the base of the tree trunk!

When morning came, it looked as if Grandon’s luck was running out. He’d made a desperate leap when the first tree started to fall and landed on another. The beasts followed and started to work on his new refuge. He’d found what felt like a coarse thick rope, and recognized it as the stem of one of the large climbing ferns he’d seen the day before. That led him to the crown of another tree twice the size of the one he left. But now the beasts had felled that one and were patiently gnawing at his. third refuge.

Now he could see them below—twelve of the most fearsome creatures he’d ever seen. They looked like hyenas, but were twice as large, their bodies covered with thick scales, black and mottled with orange spots. Each beast had three horns, one projecting from either temple, and one sprouting out between the eyes. Six of them were gnawing at the base of his tree while the other six rested. Apparently they were working in shifts.

Then he saw a man about two hundred yards away, walking with his eyes on the ground as if following a trail. He was armed with scarbo, tork, and knife, and carried a long bundle strapped to his back. Someone sent out to trail the fugitive slave, no doubt, Grandon thought. Well, he’d have a surprise soon.

A moment later, one of the beasts scented the newcomer, and uttered the laugh with which Grandon was now familiar. All work on Grandon’s tree stopped and the pack charged the stranger.
