"We"ll jump him, if we get the chance!" hissed Jim, never taking his eyes off the prints.
"Yes," came the answer; but Clee"s further words were cut off in the making by an added compulsion to keep quiet. Were their words understood? The two men were locked, speechless, where they stood. And by some creature with a human footprint whom they could not see!
The touch of firm flesh came out of the nothingness of s.p.a.ce about them, to poke and pry all over their bodies. Anger began to take the place of their fear, as, for some time, impotent of resistance, they had to submit to the examination given them. They were prodded and felt like dogs at a show; their breathing and heart action were carefully listened to; their mouths were opened and their teeth inspected as if they were horses offered for sale. Both men were inwardly fuming.
"Dogs!" shouted Clee in his thoughts. "Treating us like dogs, to see how healthy we are! Does he want us for slaves?"
At last the examination came to a stop, and they saw the shoe-prints in the rug go over to the black table and remain there, heels toward them, while various pieces of apparatus were invisibly moved across the table top. For a moment the compelling will did not seem, to Clee, to be constraining him as much is it had, and he began to wonder if he might not have a little control over his body again. Tentatively he tried to break through the oppressing blanket of foreign will; his arms and legs moved a little; he succeeded! He caught Jim"s eye and showed him. He thrilled all over at his discovery, and his will to move measurably increased with his growing confidence that he could.
The toes of the prints were still turned away. He was going to try and get the man or monster who was making them.
He gestured to Jim, and with a great effort took a step in the invisible man"s direction. A thrill of gladness helped him on--for Jim was following suit!
Again and again, with greatest mental effort, they made steps toward the footprints, which, remaining side by side and motionless, gave them increasing hope of stealing up un.o.bserved. When they were only three feet away Clee motioned to Jim, and with a tremendous effort of will they jumped at the s.p.a.ce where their enemy should be.
They hit him hard, and bore him heavily to the floor. By the feel, he was a man such as they! Clee"s blood leaped with the l.u.s.t for revenge, and blanking his mind against strong urges to cease his attack he rained savage blows at the place he was holding.
But almost at once they had evidence that their opponent was not such a man as they. A terrific pain stabbed suddenly through them, and they doubled up on the floor, writhing in agony. It was as if every nerve in their bodies had turned into white-hot wire, and was searing through their flesh. Again and again came the terrible stabs of pain--and their source seemed to be the mysterious lumps at the back of their necks!
At last they ceased coming, and Jim and Clee stretched out on the floor all but unconscious from the terrific shocks of fiery agony.
They were completely helpless; further thoughts of resistance were unthinkable. But they were not left lying long. There came a telepathic compulsion to stand up; and they found themselves obeying, in spite of the shrieking protest of their every nerve.
Twitching, stumbling, they were made to do servile things--to kneel on the floor; get up again; turn round and round; bow low, then stretch backwards. And out of the air around them came shocking blows which landed on their faces, necks and chests; feet which kicked out at their shins; and they had to stand there and take it, helpless to resist.
Then Clee, as the nearer of the two men, was pushed over to the work-table, where an oval head-piece of finely-woven wire was fitted over his head. Another very large one, standing next to it, and connected to it by wires which led to a small instrument panel nearby, lifted into the air until it must have settled about the head of their persecutor. A dial on the panel turned slowly. And gradually the helmet resting in the air dissolved into nothingness before their eyes.
A slight nausea swept over Clee as it did so, and in the midst of it he felt a series of sharp, staccato thoughts--thoughts which did not seem to be composed of words, and yet were clear and intelligible.
"Fool of a fool!" crackled in his brain with almost a physical effort, "do you think to resist Xantra? Do you think with your sub-human minds to overcome one of the Tillas, Masters of the Universe? Close you were to death--and death indeed would have come had I not other plans for you.
"Know that henceforth you and your companion are my slaves. You will jump at my slightest will; serve me as best you can with such intelligence as you may possess. For faithful, willing service you shall have food and clothing and a portion of leisure. Disobedience and tardiness will bring you the pain you have already tasted; revolt, or the attempt to escape--death; but only after torture such as you have never known.
"I shall never repeat this mode of communication: it is as physically nauseating to me as to you. And you may never expect to see me, though I can always see you. By vibrational means I have given you the universal atomic rhythm of all Tillian slaves; and, although in that state your fellow-slaves will be visible to you, I, your master, will not!
"You will now return to your place of confinement. After you have recovered you will be taken in hand by your fellow-slaves and shown your duties. And if your instinct for self-preservation is only one-tenth normal, you will never again be such a stupid sub-animal fool as to attempt to resist Xantra--to fly in the face of the inevitable!"
The sharp, staccato voice in Clee"s brain stopped; his nausea began to leave him; his helmet was removed; and had he been looking he might have seen the other one slowly materialize on the table. The ordeal was over just in time, for the last remnants of his strength was giving out--as was Jim"s. The two Earth-men slumped down, and would have fallen but for the telepathic will, stronger than theirs, that forced them erect again. There came a very strong compulsion to return to their cell, and bruised, stumbling, their nerves still afire from their strange stabbing pains, they made their way back.
They fell to the floor and pa.s.sed into unconsciousness--beaten, subdued. Slaves....
After a long blank interval a distinct thought crossed Clee"s mind. He was in heaven, and an angel voice had spoken. There it was again! Cool hands were stroking his wrists and forehead. He opened his eyes and looked, but seeing no one closed them again.
The Voice returned, and two of the words which kept repeating were somehow familiar. "So sorry ... so sorry...." The Voice was low and cool and feminine. And someone was bathing his battered head.... He rolled over and got up on one elbow. He still could see no one.
The Voice said: "Oh, I"m so glad you"re better! I thought you"d never come to!"
Mechanically Clee asked: "Who are you?"
"Vivian Gray," came the quick answer; "from Boston. And you?"
Clee did not answer, but started to lie back again. Things were all wrong: he couldn"t even see anyone. He"d go back to sleep, and wake up some other time. But the Voice wouldn"t let him.
"Oh, you must listen!" it said. "I haven"t much time!"
"Where are you?" he asked.
"Why--right here!" came the surprised answer. "Can"t you see me?"
"No," answered Clee, still not himself. He added categorically: "I can see Jim. I can see the door. I can see my hands, but I can"t see you."
"Oh, then it must be true! Xantra _told_ me he was going to make you one of his common slaves; but I hoped--I hoped--"
This didn"t mean much to Clee; but with the words came memory of all that had happened, and with sudden concern he crept over to where Jim was lying, to see how he was. He found him blinking and stirring, aroused by the voices. Quickly he explained the invisible presence to him, warning him to be on guard.
"Oh, but I"m a friend--Vivian Gray--kidnapped from Earth just like you!" came quick explanation out of the air. "Xantra stole me from Cape Cod, where I was vacationing, about the time he took you. Xantra is the one whose s.p.a.ce ship we are on. He looks much like a man; he is some kind of a man; but he"s not from Earth--"
"You"ve _seen_ him?" interrupted Clee, beginning to believe the Voice a little.
"Yes," came the instant response; "not when he abducted me--he had made himself invisible for that--but always after. Haven"t you yet?"
And then, without waiting for his answer, she gave it herself. "But of course you couldn"t see him if he"s already given you the universal atomic rhythm the slaves have. You"d then be able to see only each other, and the other slaves; not Xantra and not me.
"I think he makes his slaves that way for protection," she explained.
"They can"t very well plot or rebel against him when they can"t even see him, and never know but what he"s around."
"Who are these slaves you keep mentioning?" Jim broke in. "How many of them are there on this ship: and how many like Xantra?"
"Xantra is the only one of his kind," came the answer. "The slaves are a race of inferior people found on his planet--wherever that is: I couldn"t understand, from his explanation, just where. They are creatures much like ugly human beings with a touch of the ape, and are entirely bald, very strong and not very intelligent. There"re seven or eight on board. Normally they are good-natured: but sometimes when they have a hard master, like Xantra, they take to hating him; and when they do that they can be very fierce and treacherous. That"s the main reason for Xantra"s stopping at Earth: to see what kind of slaves we humans will make. He is hoping that we will be more intelligent than those he has--and more docile, and safer to have around."
"Well," snorted Jim belligerently, "if Mr. Xantra thinks that I"m going to be safe to have around, he"s a lot dumber than _I_ am!"
"Oh, it"s good to hear you talk that way," the girl"s voice went on.
"We three have got to stick together, and find some way to escape!
"I"ve so much to say!" she went on; "but I daren"t stay long, for fear of getting caught. What you said is where my chief hope lies: Xantra doesn"t realize how intelligent we are, and how dangerous; and we mustn"t let him know! I think he believes we are much like his present slaves: he gets away with murder with them. You"ve noticed the lumps on the back of your necks? Well, they have them, too; it"s something that"s attached to the spinal cord and gives him telepathic control over them; also the power to hurt them dreadfully--as you"ve unfortunately found out. His slaves don"t understand these lumps; they don"t seem to know that he would lose control if they could only in some way get rid of the things in their necks!"
