Eighty-three erds! Practically a million Earth miles. Already they had swung out to a new orbit between those of Ganymede and Callisto. And what of the effect on the other satellites? Blaine listened carefully as the astronomer continued.

"Perturbations in the movements of the other bodies in our own system are marked, and, in the case of the first satellite, have proved disastrous. It has commenced its inward journey and soon will have fallen into the gaseous envelope of the mother body. But this need occasion us no concern; it is small and there will be stabilization of the others after the second charge is fired."

Colossal conceit! What amazing ignorance or oversight of natural laws!

These Llott scientists could see no farther than their snub noses, or at least no farther than the satellite system of Jupiter. And Ianito was complimenting the astronomer on his good work!

The group broke up now and the Dictator turned to the controls of his crystal sphere. Blaine and Ulana caught the view of the underground laboratory at the base of the great rocket-tube.

All was as it had been when they first saw this chamber. The breech of the huge cannon had cooled and its ma.s.sive block was open. Tommy was there, fishing the radium capsule from the powdery residue in order that it might be used in exciting the next charge. A mechanical precision marked his every motion.

"It is good," Ianito grunted, flicking a lever that cut off the view.

"We are progressing nicely, thanks to the generosity of the Earth beings in providing this k-metal."

His sarcastic grin was infuriating. Dantor cast a warning look in the Earth man's direction. It wouldn't do to lock horns with this self-satisfied despot; at any rate, not now. Blaine's mien was expressionless as he faced him.

The view in the crystal was another familiar one when Ianito made a quick readjustment: the throne room in the palace of the Zara! The Dictator snorted when he saw that Clyone was reclining lazily on her golden couch, submitting graciously to the ministrations of her handmaidens.

"Faithless creature!" he snarled. "Harlot! Parricide! But at last Ianito will have his revenge."

The hate in his voice and in those terrible gla.s.s-hard eyes was devastating in its intensity: implacable, relentless. Yet Blaine could not down the exultant feeling that came to him when he saw that this monster could suffer, too.

"What's the matter?" he sneered. "Did she throw you down?" He could have bitten off his tongue as he spoke. Ulana gasped.

And if Ianito had been in a rage before he was a madman now. Despite his contempt of the misshapen creature, Blaine quailed before the murderous glare that answered his rash words. But the Dictator was master of himself, at that; his lips tightened in a thin line and he held his peace. He actually smiled after a moment, the devil, a smile, though, of evil triumph. He turned once more to the crystal and switched on the sound mechanism.

"Clyone," he called, in velvety voice; "it is Ianito."

She looked up, startled, her chalky face gone whiter still. Her jeweled fingers fluttered to the smooth throat.

"I hear you," she replied shakily. "What do you wish of me."

"Nothing much--this time. I have visitors who request an audience with you, oh Clyone. Can you see them at once?"

"Who--who are they?" Her eyes widened at his insinuating tone.

"An Earth man--Carson--and the Rulan maiden who is to become his mate."

Ianito chuckled evilly as he watched her expression.

"Carson?" she whispered, her wild eyes softening, "He--he lives?" Black hatred replaced the wondering joy that had glowed in her face. She was thinking of the statement regarding the Rulan maiden. "Why, yes," she snapped, suddenly very much alert; "I can see them. Send them immediately."

The Dictator chortled as he switched off the power. Dantor paled and looked away. So this was his scheme! He was sending Ulana to certain death at the hands of the leopard woman. Blaine bit his lips until they bled. If only he had one of their ray pistols again. If he had--

Ianito was at his side, whispering. But he couldn't see him; the devil had donned one of Dantor's invisible cloaks. Something hard pressed deep into his ribs.

"I shall be with you," the Dictator told him, "but she will not know.

It is necessary, of course, that I watch over you in order that your deportment be suitable to the occasion. The death ray of Antrid is ready in my hands. Proceed, you and the Rulan maid, and see to it that you give her every attention while in the Zara's presence."

Dantor interposed an objection, "But, Ianito, you promised to spare them. I learned to love these two and want no harm to come their way."

"I keep my promise, oh Dantor. Ianito will not harm them."

"But the Zara."

"What Clyone does is none of my concern. Silence, Dantor; I command it!

You will remain here." The voice of the Dictator cut like a knife.

The old Rulan scientist bowed his head and turned away. Good old Dantor! He'd done all in his power to help them. This was the end; not a question of doubt. Blaine Carson drew the Rulan maiden fiercely to him. This Clyone might meet some opposition if she attempted to wreak her spite on Ulana; she _would_ meet it. There was no need for Ianito to ask that he pay every attention to the lovely, frightened girl who clung to him so trustingly.

They were in the lift then, dropping swiftly into the palace beneath the great dome that topped Antrid.

"This Clyone," Ulana whispered, "she has great power of enticement, my Carson. I fear for your loss--to me. She will take you from me, and I shall be alone--or dead. Death would be the better."

"Never!" said Blaine huskily. "Never, my dear. She has no power over me; nor will I permit her to bring suffering to you."

Ianito laughed then, an ugly cackle that came out of the unseen.

CHAPTER X

_Clyone and Ulana_

The Zara received them in the throne room, alone. Blaine hesitated as he crossed the threshold, Ulana's trembling fingers tightly clasped in his own. The quick prod of the invisible ray pistol warned him that Ianito was at his heels.

Clyone uncurled her sinuous, black-sheathed body and rose to her feet as they neared the dais.

"Welcome, oh Carson," she purred. "Clyone has mourned you as dead, but she mourns no longer. A kind fate has returned you."

The gold-flecked eyes were all for him; it was as if she did not see his companion. Blaine fought the spell of her with all that was in him.

He did not reply.

"Come to me, Carson," she pleaded, her lashes lowered. "Leave this Rulan girl and come to me."

"Where I go she goes," he replied firmly.

"Very well then," said the Zara meekly, "bring her with you. I would converse with her as with you."

Something new, this was: a gentleness Blaine had never thought the leopard woman could exhibit, even in sham. And her eyes, when she raised them, still were gentle. She extended a white arm and smiled provocatively. If this was a ruse, if she meant harm to the Rulan maid, her acting was superb. And, from what he had seen of the woman previously, he was almost convinced of her sincerity. A nature like hers was incapable of successful dissimulation. Still, he was suspicious and he shielded Ulana with his body as they came up to the throne. The Zara studied them in silence for a while. Then she spoke.

"Let me look at you, my dear," she said to the Rulan maiden.
