"Your son?" he asked gently. "Has he the triangular brand?"

The Zar was taken aback. "He has, yes. Why?" he asked.

"I have seen him in the Americas. He now lies wounded and in peril of his life. What do you think of that?"

Karl was triumphant as the Zar paled.

"You lie, Peter Van Dorn!"

But the beady eyes saw that the young man was truthful. Sudden fury a.s.sailed the monarch of the East. A bell pealed its mellow summons and three Moon men entered the Presence.

"Quick, Taru--the radiovision! Our amba.s.sador in the Americas!" The Zar was on his feet, his hard features terrible in fear and anger. "By G.o.d!"

he vowed, "I'll lay waste the Americas if harm has come to my son. And you"--turning to Karl--"I'll reserve for you an even more terrible fate than the vibrating death!"

The radiovision was wheeled in and in operation. A frightened face appeared in its disc: the Zar's amba.s.sador across the sea.

"Moreau--my son!" snapped the Zar. "Where is he?"

"Majesty! Have mercy!" gasped Moreau. "Paul has eluded us. He was skylarking--in the lower levels of New York. But our secret agents are combing the pa.s.sages. We'll have him in twenty-four hours. I promise!"

The rage of the Zar was terrible to see. Karl expected momentarily that the white flame would lay him low, for the anger of the mad ruler was directed first at Moreau, then at himself. But a quick, evil calm succeeded the storm.

"You, Peter," he stated, in tones suddenly silky, "shall have that twenty-four hours--no more. If Moreau has not produced my son in that time you shall be dismembered slowly. A finger; an ear; your tongue; a hand--until you reveal the whereabouts of the heir to my throne!"

"Never! You sc.u.m!" Karl was on the dais in a single bound. He had the Zar by the throat, his fingers twisting in the flabby flesh. Might as well have it over at once. "Fratricide--murderer of my father, I'll take you with me!"

But it was not to be. The throne room was filled with retainers of the mad emperor. Strong hands tore him away and he was borne, struggling and fighting, to the floor. A sharp pain in his forearm. A deadening of the muscles. He was powerless, save for the painful ability to crawl to his knees, swaying drunkenly. A delicious languor overcame him. Nothing mattered now. He saw that a tall man in the purple had withdrawn the needle of the hypodermic and was replacing the instrument in its case.

Ever so slowly, it seemed.

The Zar was laughing. That horrible cackle. But Karl didn't care. They'd have their sport with him. Let 'em! Then it'd be over. Lord! If only he had been a little quicker. He'd have torn the old Zar's windpipe from its place!

"My word," laughed the Zar. "The sacred word of a Van Dorn. I gave it.

He'll wear the purple for a day. Take him from my sight!"

Karl was walking, quite willingly now. The effects of the drug were altering. His muscular strength returned but his mental state underwent a complete change. Always he'd wanted a taste of the purple. For years he'd listened to the orators of the Square, to the conflicting statements of old Kra.s.sin. But now he'd see. He'd know the joys of the upper levels; the pleasure cities, perhaps. For one day. But what did it matter? He found himself laughing and joking with his companion, a heavy-set wearer of the purple. They were in a luxurious apartment.

Servants! Moon men all of them, but so efficient. They stripped him of his gray denim; discarded it contemptuously. Karl kicked the heap into a corner and laughed delightedly. His bath was waiting.

Much can happen in a day. Clothed in the purple, Karl--Peter Van Dorn, he was, now--expanded. Turgid emotions surged through his new being. He was a new man. In his rightful place. He was delighted with the companionship of his new friend of the purple, Leon Lemaire. An euphonious name! A fine fellow! Fool that the Zar must be, to leave him in the care of so amiable a man. Why, Leon couldn't hold him! None of them could. He'd escape them all--if he wished. Twenty-four hours, indeed!

They were in the midst of a gay company. Wine flowed freely, and Leon had attached to their party a pair of beautiful damsels, young, and easy to know. There was music and dancing. Lights of marvelous color played over the a.s.semblage in the huge hall, swaying their senses at the will of some expert manipulator. Peter was a different person now. He was exhilarated to the point of intoxication, but not by the wine. Somehow he couldn't bear the taste of the amber fluid the others were imbibing with such gusto. The effects of the drug had left a coppery taste in his mouth. But no matter! Rhoda, his lovely companion at the table leaned close. Her breath was hot at his throat. He swept her into his arms.

Leon and the other girl laughed approvingly.

There were many such places in the upper levels of Dorn and they traveled from one to another. Now their party was larger, it having been augmented by the appearance of other of Leon's friends. Fine companions, these men of the purple, and the women were incomparable.

Especially Rhoda. They understood one another perfectly now. It was all as he had pictured it.

Someone proposed that they visit the intermediate levels. It would be such a lark to watch the mechanicals. They made the drop in a lift. A laughing, riotous party. And Peter was one of them! He felt that he had known them for years. Rhoda clung to his arm, and the languorous glances from under her long lashes set the blood racing madly in his veins.

In the levels of the mechanicals they romped boisterously. To them the strange robots--creatures of steel and gla.s.s and copper--were objects of ridicule. Poor, senseless mechanisms that performed the tasks that made the wearers of the purple independent of labor. Here they saw the preparation of their synthetic food, untouched by human hands. In one chamber a group of mechanicals, soulless and brainless, engaged in the delicate chemical compounding of raw materials that went into the making of their clothing. Here was a nursery, where tiny tots born to the purple were reared to adolescence by unfeeling but efficient mechanical nurses. The mothers of the purple could not be bothered with their offspring until they had reached the age of reason. The whirring machinery of a huge power plant provided much amus.e.m.e.nt for the feminine members of the party. It was all so ma.s.sive; throbbing with energy. But dirty! Ugh! Lucky the attendants could be mechanicals.

"We have visited the lower levels," whispered Rhoda in his ear, "but not often. It isn't pleasant. Ignorant fools in the gray denim--too many of them. I don't know why we permit their existence. Fools who will not learn. Education made us as we are, and they won't take it. Sullen looks and evil leers are all that they have for us. Hope n.o.body suggests going down there now."

"Me, too," said Peter. He had forgotten that once he was Karl Kra.s.sin, a wearer of the despised gray.

Someone in the party was becoming restless. They must move on.

"Where to?" asked Peter.

"Sans Dolor, sweet boy. A pleasure city within a hundred kilometers of Dorn. You'll love it, Peter."

A pleasure city! Fondest dream of the wearers of the gray! In the dim past, when he was Karl, he had dreamed it often. Now he was to visit one!

They were atop the city now and the crystal palace of the Zar shimmered in the sunlight off there across the flat upper surface of Dorn. But it seemed so far away that Peter did not give it a second thought. He was living in the present.

A swift aero took them into the skies and they roared out above the wilderness that was everywhere between the great cities of earth. Funny n.o.body thought of leaving the cities and exploring the jungles of the outside. But, of course, it wasn't necessary. They had everything they needed within the cities. All of their wants were supplied by the mechanicals and by the few toilers in the gray who still persisted in ignorance and in some perverse ideas that they must work in order to live. Besides, the jungle was dangerous.

Sans Dolor loomed into view, a great island floating in the air a thousand meters above the tossing waters of the ocean. Peter gave not a thought to the forces that kept it suspended. Dimly he recalled certain words of old Rudolph, words regarding the artificial emanations that had been discovered as capable of counteracting the force of gravity. But his mind was intent on the pleasures to come.

They were over the city. Carefully tended foliage lined its streets and a smooth lagoon glistened in its center. Its towers and spires were decorated with gay colors. The streets were filled with wearers of the purple and the nude bodies of bathers in the lagoon gleamed white in the strong sunlight.

He sensed anew the nearness of Rhoda. Her soft warm hand nestled in his and she responded instantly to his sudden embrace.

There came a shock and the party was stilled in dismay. The aero careened violently and the pilot struggled with controls that were dead.

Sans Dolor dropped rapidly away beneath them. They were shooting skyward, drawn by some inexplicable and invisible energy from above.

Rhoda screamed and held him close, trembling violently. All of the women screamed and the men cursed. Leon arose to his feet and stared at Peter.

The friendliness was gone from his features and he spat forth an accusation. A glistening mechanism appeared in his hand as if by magic.

A ray generator! He had been appointed by the Zar to guard this upstart and, whatever happened, he'd not let him escape with his life. The girl shuddered at sight of the weapon and extricated herself from his arms.

Her affection too had been a pose.

Peter's mind was clearing from the effects of the drug. He had not the slightest idea of what might have caused the quick change in the situation but he resolved he would die fighting, if die he must. Leon fumbled with the catch of the generator. It refused to operate. The force that was drawing them upward had paralyzed all mechanisms aboard the little aero. Flinging it from him in disgust he sprang for Peter.

Their minds befuddled, the rest of the men watched dully. The women huddled together in a corner, whimpering. They were a sorry lot after all, thought Karl. He was no longer Peter Van Dorn, and he thrilled to the joy of battle.

Leon Lemaire was no mean antagonist. His flailing arms were everywhere and a huge fist caught Karl on the side of his head and sent him reeling. But this only served to clear his mind further and to fill him with a cold rage. He bored in unmercifully and Lemaire soon was on the defensive. A blow to his midsection had him puffing and Karl hammered in rights and lefts to the now sinister face that rocked his opponent to his heels. But the minion of the Zar was crafty. He slid to the floor as if groggy, then with catlike agility, dove for Karl's knees, bringing him down with a crash.
