possessed as strong a magnetic field as did the inner planets. Antazzo now consulted a chart which he drew from his pocket, and examined minutely the surface over which they were speeding. Here and there curious designs were etched on the copper plates, and it was from these he determined their course. Obviously there was an entrance to this sealed-in world.

When they had proceeded some two thousand miles in a northeasterly direction Antazzo gave the order to reduce speed. Off at the horizon there appeared a bulge in the copper surface, a round protuberance that resolved itself into a great dome-shaped structure as they drew nearer. A full two hundred feet it reared itself into the heavens, and Blaine saw a number of large circular hatches in its side that evidently covered air-locked entrances.

"You will land close by the dome, Carson," Antazzo barked, "and both of you will get into your moon-suits."

At his tone Blaine saw red. He realized on the instant that the effect of the pink gas had worn off and that he was his own master once more. All the pent-up emotions of the past few days were unleashed. If only he could get in one good punch. They might get away yet. There was plenty of k-metal to replenish the fuel supply. He whirled suddenly, muscles tensed. He faced the grinning hunchback—and was greeted by a breathtaking spurt of the pink gas. This time it was not merely a subjecting of his own will to that of the master but a complete hypnotism, a somnambulistic state. As in a dream he turned to the controls.

Now it came to him that the dwarf no longer spoke. He worked his will entirely without words; his evil mind possessed fully the mind of his victim. For Blaine Carson there was no further independent thinking. He was an automaton, a sleep-walker.

Like a detached and more or less disinterested observer, he saw that he had landed the ship. Then he noticed three dwarfs in bulky, helmeted moon-suits, shuffling clumsily across the copper plates. Hazily he knew he was with the others in an airlock; the hiss and the throbbing of pumps told him that. Under the great dome there was the latticework of a huge reflecting telescope; strange pigmy figures scuttled here and there, working at curious machines. There was the constant purr of many motors, the gentle pulsation of floor-plates beneath his feet.

With the moon-suit removed, he realized the atmosphere was fetid and stifling. A great pressure bore on his lungs, making breathing labored and difficult. And then they were in a lift that dropped into the depths of its shaft with dizzying speed. Antazzo's grin; Tom's eyes, dull and lifeless, floating there in the haze before his own—it was all a nightmare from which he must soon awaken.

There followed a period of complete unconsciousness of movement and of his surroundings. Light—light everywhere; a blue-white radiance that beat upon his unseeing eyes with unrelenting ferocity. Stabbing pains bored into his very brain, pains that carried with them an unspoken and unintelligible command. Why couldn't they let him alone; leave him to die in peace? He knew he was on his feet, swaying. There were voices, strident and guttural, and then by some magic the veil was lifted. His brain cleared and he saw that he stood before a dais where a much bejeweled and resplendently clad woman sat curled in the luxurious cushions of a golden seat. Chalk-white was her face and her lips crimson; amazing eyes, cat's eyes, pupils red-flecked and glittering, stared out at him.

"The Zara," Antazzo whispered. "You will make obeisance."

Mechanically, Blaine dropped to his knees and touched his forehead to the floor. Tom Farley, over there, was doing the same, but Antazzo stood erect with arms crossed over his chest and head thrown back. The eyes of the Zara swept him contemptuously from head to foot. All was not well between them.

Blaine arose from his humiliating position at a sharp command from the hunchback. Tommy did likewise and the two exchanged sheepish looks. The effects of the pink gas were wearing off once more. They were in a large hall, obviously the throne room of a palace. Men-at-arms lined the walls on either side of the dais, and these were straight limbed giants with green-bronze skin and regular features—not at all like the deformed Ionian who had captured them and stolen the RX8.

The Zara talked rapidly in throaty gutturals, her fierce gaze directed at Antazzo and her brows drawn together in a scowl that could have but one meaning. She was displeased with the hunchback, displeased and furiously angry. What was it all about? Hadn't he brought home the bacon—the k-metal they were after? Blaine was nonplused.

Then Antazzo replied to the woman who was obviously his queen. His voice rose in shrill disagreement and his scowl was as fierce as the Zara's. Threatening her, he was, the nervy devil. He clenched his fists and raised his arms in an angry gesture, pacing the floor in his fury and thrusting out a pugnacious chin while he raved. This Zara woman rose higher in her cushions, and the look that flashed from those terrible eyes would have warned a less excited human, however justifiable his anger might be. But Antazzo was in too deep to draw back, that was plain to be seen. Blaine held his breath in anticipation of an explosion.

It came then, that explosion, and in a way entirely unexpected and horrible to behold. The tiger woman uttered one fierce sibilant like the hiss of a serpent, a terrifying sound that silenced the hunchback and brought him stiffly to attention, mouth open and eyes bulging with horror. One of those unbelievably white arms stretched forth, threateningly tense, and a jeweled finger leveled itself at the rash Ionian. From it there flashed an intangible something that leaped to bridge the distance with the speed of light, something that screeched as it flew and crashed like breaking glass when it struck Antazzo's horrified face. In an instant he was on the floor, screaming and writhing in mortal agony.

The Zara watched with compressed lips and livid features as a host of black disk-like things covered the squirming body, spinning madly as if driven by atomic energy and emitting a myriad high-pitched tones like the angry buzzing of a swarm of bees. Antazzo's body shriveled as the things hummed on in their devilish work. Soon there was but a tiny heap of clothing with the angry black disks whirling and singing their song of hate. And then, in a puff of thick yellow vapor they were gone, their gruesome work completed. The odor of putrefaction lay heavy on the air.

Blaine shuddered and a fit of nausea twisted his vitals. It served the devil right, of course, but it was a horrible way to go. These damned Ionians, even to their queen, were bloodthirsty creatures. And what devilish ingenuity they had displayed in their development of weapons! His eyes were drawn irresistibly to the flaming orbs of the Zara.

She was actually smiling at him, this beautiful, heartless animal, not a smile of derision but one of deliberate allure. He felt the hot blood mount to his temples. A languid arm beckoned him to her side and the amazing creature settled back in her cushions with the drowsy, contented motions of a lazy feline.

"Watch your step!" Tommy hissed.

That warning was unnecessary. Blaine shook his head and backed away from the dais, an instinctive recoiling from a loathsome thing. The Zara saw and understood; and she went again into a black rage. She sat stiffly erect and called rapid orders to her men-at-arms.

The Earth men were surrounded instantly, their arms and legs pinioned by powerful hands, their feeble resistance overcome by the bronze giants as easily as if they had been children. Helpless and hopeless, they were
