passed among the prisoners. Here and there he halted, snatching some article of finery or inconspicuous bit of jewelry that he had overlooked before. They shrank from him, only too glad to see him pass on to the next unfortunate.

"You, there!" Gore rasped, indicating Quirl with his stubby forefinger. "Come on out o' there, you!"

Quirl hoped that the brutal mate would not hear the thudding of his beating heart, or that if he did, he would take it for fear. He came slowly toward Gore, who was greedily eyeing the young man's brightly colored and valuable tunic. Quirl came too slowly.

"What do you take me for?" Gore bellowed in unreasonable anger. He strode forward, the prisoners scattering before him. His large, knotty hand closed on Quirl's arm, and jerked, with the intention of whirling this reluctant prisoner across the room. But Quirl was heavier, and his arm harder, than Gore had supposed. The hand came away, and with a tearing scream, the beautiful silk garment ripped off, ruined, disclosing Quirl's white and well-knit body.

"You done that a-purpose!" Gore roared, and then his great ape's arms were around Quirl, trying to break his back.

But that seemingly slight body would not bend, and, as much as Gore might tug and heave, he could not force Quirl back. The little pig-eyes glared, and there was death in them. Suddenly Gore let go. His hand leaped to the short club at his side, and he swung the weapon in a vicious arc. Quirl's relaxed forearm met it, sapping most of its force. Yet when it struck his head it seemed to burst like a ball of fire. He crashed against the wall and sank to the floor only half conscious.

"Gore! Gore!" yelled the guard from the platform, "'member how sore the Old Man was about the last terrie you killed? Better lay off."

"Shut yo'r damned mug!" Gore yelled back. But he gave up his idea of kicking the prisoner, and with a menacing glare for the guard, passed on.

As Quirl's mind slowly cleared he congratulated himself for his repression. During his struggle with Gore his hand had come in contact with the butt of the mate's electrogun. He could easily have pulled it out of its holster and turned it against its owner. But this hasty action would not only have assured his own death, but would have destroyed the only chance the I.F.P. had of learning "The Scourge's" secrets.

Gore slowly worked his way to the women's side of the hold. Here, much to the amusement of the guard and himself, he began stripping off their long, flowing robes, disclosing their nude bodies. He seemed to see particular humor to heaping indignity on the older women, commenting coarsely on their shortcomings. The men viewed this with set, pale faces. But none dared to interfere. In their midst was an object lesson, his head swathed in bandages. He had been the first to resent this exhibition, an almost daily event, when the mate's roving eye had happened to alight upon his wife.

All at once Gore's careless and derogatory progress was halted, and he stared with terrifying intentness at the girl who had until that day managed to escape his notice. Gore had torn off a nondescript black cape that had covered her head and face, and the golden silk robe she wore. To Quirl, watching from a space of some sixty feet, her beauty came like a shock. He remembered her as Lenore Hyde, whom he had seen only once before as she emerged briefly from her stateroom.

About five feet, six inches tall, her slim figure was dwarfed by the huge bulk of the mate. Her golden hair tumbled over her slim shoulders, almost to her waist, where a tasseled cord held the clinging silk close to her. Her face, so white that it seemed like silver in that gorgeous setting, was cold and defiant. There was no fear in those deep blue eyes under the straight brows—only loathing and contempt.

Gore was not concerned with the personal feelings of his prize. He licked his wide, cruel lips, seizing the girl's arms as in a vise. His other big, dirty hand slipped into the collar of her robe.

But the ripping of fabric did not come. Instead there was a sharp crack, and Gore, too surprised even to move, stared at the little man who had hit him.

Again crack! The impact of fist on jaw. The blow was too weak to hurt this toughened veteran of countless battles. But slowly a tide of dull red welled up over the bull neck, turning the blue-black jowls to purple, and the walls echoed to Gore's roar of anger.

Again the fists of the smaller man smacked, this time drawing a trickle of blood from Gore's mouth. Then the thick fingers closed on the brave passenger's wrist, and the tremendous muscles swelled as, with a quick movement, Gore thrust his adversary back of him, grasping the other wrist also. Then with slow, irresistible motion, he began drawing the thin arms forward, stretching them, until the unfortunate man, drawn against the barrier of Gore's back, began to shriek with pain.

Still Gore pulled, grinning evilly, and his victim's shoulder blades lifted under the tight skin of his back as they took the strain. Shriek followed shriek, until the guard on the platform glanced furtively out into the central well. There came a dry, tearing crackle as the bones of the arms were drawn out of their sockets, and then the shrieks ceased as merciful unconsciousness came. Gore tossed the limp body carelessly away.

"The beast!" Quirl gritted his teeth. But he stayed where he was, hiding his clenched fist, for his was a specific assignment, and men of the I.F.P. know the meaning of the word "duty."

In a better humor again, Gore looked around.

"Come on, you little ginny!" he chortled. "I see you! Come to Moby, my beauty. You'll be queen of the hold, and this scurvy litter will kiss your feet every day."

He pursued her as she ran, bowling over or trampling on the fear-stricken prisoners as they tried to scramble out of his way, men and women alike. But she made up in agility what she lacked in strength, lifting up the hem of her robe so that her legs twinkled bare, ducking under Gore's outstretched arms, or leaping over the fallen form of some stumbling, panic-stricken unfortunate.

Only in her eyes was there a true picture of her terror. Gore's uncertain temper was changing again, and in a few moments he was cursing foully, his little red-rimmed eyes glistening, as he dashed after her with short, boar-like rushes.

Again she skimmed past where Quirl cowered in simulated fear, and the look she gave him struck straight at the disguised officer's heart. So it was that when she slipped and fell to her knees, and Gore charged in with a triumphant laugh, Quirl met him with no thought of anything, no feeling but the joy of battle, the delight of a strong man when he meets a foe whom he hates. And to that heady, feral emotion was added the unforgettable picture of a lovely face whose obvious fear was somehow tempered by hope and confidence—in him!

As Gore lunged past, Quirl struck him. It was a short, sharp, well-timed jab that would have knocked out an ordinary man. But Gore was by no means ordinary. The blow laid open his cheek against the jawbone, but Gore scarcely slowed as he swerved. With a bellow of rage, he came straight at Quirl, arms outstretched.

Philosophers have said that no matter how far the human race advances in the sciences, its fundamental reactions will still be atavistic. Gore could have dispatched Quirl in a second with his ray weapon, with perfect safety. Yet it is doubtful that the weapon even entered his mind. As he came to the battle he was driven only by the primitive urge to fight with his hands, to maim, to tear limb from limb like the great simians whom he resembled.

To Quirl, coolly poised, the picture of Gore did not inspire terror. In the passengers, it did. They saw a brutal giant, gorilla-like, and roaring like a beast, charging at a half-naked
