Tommy frowned unhappily in the darkness. If he sent her back, she would know it was because he knew danger lurked here. Then she would worry. If he did not send her back....

"I'll go back the minute you tell me," she insisted forlornly.

"Honestly. But--I was lonesome."

Tommy slipped his arm about her.

"Woman," he said sternly. "I'm going to let you stay ten minutes, so you can brag to our grandchildren that you were the first Earth-girl ever to be kissed in the Fifth Dimension. But I want you down in the laboratory so you won't be in my way if I start running!"

His tone was the right one. She even laughed a little, softly, as he pressed her to him. Then she clung to his hand and tried eagerly to pierce the darkness all about them.

"You'll be able to see something presently," he a.s.sured her in a low tone. "Just keep quiet, now."

She gazed up at the stars, then around in the so-nearly complete obscurity. Tommy answered her comments abstractedly, after a little.

He was not quite sure that certain irregular sounds, yet far distant, were not actually quite regular ones. The Ragged Men Smithers had shot into had run away. But they would come back and they might come with Jacaro and his gunmen as allies. If those distant sounds were men....

She withdrew her hand from his. Her back was toward him then, as she tried to pierce the darkness with her eyes. Tommy listened uneasily to the distant sound. Suddenly he felt Evelyn b.u.mp against his shoulder.

He turned sharply--and she was out of the Tube! She was walking steadily off into the darkness!

"Evelyn! Evelyn!"

She did not falter or turn. He switched on the flashlight beneath his gun barrel and leaped out of the Tube himself. The light swept about.

Evelyn's lithe figure kept moving away from him. Then his heart stood still. There were eyes beyond her in the darkness, huge, monstrous, steady eyes, half a yard apart in a head like something out of h.e.l.l.

And he could not fire because Evelyn was between the Thing and himself. Its eyes glowed unholily--fascinating, hypnotic, insane....

Evelyn swayed ... and the Thing moved! Tommy leaped like a madman shouting. As his feet struck the ground a ma.s.s of sold-seeming fungus gave way beneath him. He fell sprawling, but clutching the gun fast.

The spreading beam of the flashlight showed him Evelyn turning, her face filled with a wakening horror--the horror of one released from the fascination of a snake. She screamed his name.

Then a huge lizard paw swept forward and seized her body. A second gripped her as she screamed again. And Tommy Reames was deathly, terribly cool. The whole thing had happened in seconds only. He was submerged in slimy, sticky ooze which was the crushed fungus that had tripped him. But he cleared the gun. The flashlight limned a ghastly, obscenely fat body and a long tapering tail. Tommy aimed at the base of that tail and pulled the trigger, praying frenziedly.

A stream of flame leaped from the gun-muzzle. Explosive bullets uttered their queer cracking noise. The thing screamed horribly. Its cry was hoa.r.s.ely shrill. The flashlight showed it swinging ponderously about, with Evelyn held fast against its body in a fashion horribly reminiscent of a child holding a doll.

Tommy was scrambling upright. Jaws clamped, cold horror filling him, he aimed again, at the sharp-toothed head above Evelyn's body. He could not try a heart shot with her in the way. Again the gun spat out a burst of explosive lead. And Tommy should have been sickened by the effect of detonating missiles. The thing's lower jaw was shattered, half severed, made useless. It should have been killed a dozen times over.

But it screamed again until the jungle rang with the uproar, and then it fled, still screaming and still holding Evelyn clutched fast against its scaly breast.

CHAPTER IV

_The Fifth-Dimension World_

Tommy flung himself in pursuit, despairing. Evelyn cried out once more as the lumbering thing fled with her, giving utterance to shrieking outcries at which the tree-fern jungle shook. It leaped once, upon monstrous hind legs, but came crashing heavily to the ground. Tommy's explosive bullets had shattered the bones which supported the balancing tail. Now that huge fleshy member dragged uselessly. The thing could not progress in its normal fashion of leaps covering many yards. It began to waddle clumsily, shrieking, with Evelyn clasped close. Its jaw was a shattered horror. It went marching insanely through the blackness of the jungle, and with it went the unholy din of its anguish, and behind it Tommy Reames came flinging himself frenziedly in pursuit.

Normally, the thing should have distanced him in seconds. Even crippled as it was, it moved swiftly. The scaly, duck-shaped head reared a good twenty feet above the fallen tree-fern fronds which carpeted the jungle. The monstrous splayed feet stretched a good yard and a half from front to rear upon the ground. Even its waddling footprints were yards apart, and it moved in terror.

Tommy tripped, fell, and got to his feet again, and the shrieking tumult was farther away. He raced madly toward the sound, the flashlight beam cutting swordlike through the blackness. He caught sight of the warty, scaly bulk of the monster at the extreme limit of the rays. It was moving faster than he could travel. He sobbed helpless curses at the thing and put forth superhuman exertions. He leaped fallen tree-fern trunks, he splashed through shallow ponds--later, when he knew something of the inhabitants of such pools, Tommy would turn cold at that memory--and raced on, gasping for breath while the shrieking of the thing that bore Evelyn grew more and more distant.

In five minutes he was almost strangling and the thing was half a mile ahead of him. In ten, he was exhausted, and the shrieking noise it made as it waddled away was distinctly fainter. In fifteen minutes he only heard its hooting scream between the harsh laboring rasps of his own breath as he drew it into tortured lungs. But he ran on. He leaped and climbed and ran in a terrible obliviousness to all dangers the jungle might hold.

He leaped down from one toppled tree-trunk upon what seemed be another. But the thing he landed upon gave beneath his boots in the unmistakable fashion of yielding flesh. Something vast and angry stirred and hissed furiously. Something--a head, perhaps--whipped toward him among the fallen fern-fronds. But he was racing on, sobbing, cursing, praying all at once.

Then suddenly he broke out into a profuse sweat. His breathing became easier, and then he was running lightly. His second wind had come to him. He was no longer exhausted. He felt as if he could run forever, and ran on more swiftly still. Suddenly the flashlight beam showed him a deep furrow in the rotting vegetation underfoot, and something glistened. A musky reek filled his nostrils. The thing's trail--the furrow left by its dragging tail! That musky reek was the thing's blood. It was bleeding from the wounds the explosive bullets had made.

It was spouting whatever filthy fluid ran in its veins even as it waddled onward, screaming.

Five minutes more, and he felt that he was gaining on it. Then, and he was sure of it. But it was half an hour before he actually overtook the injured monster marching like a mad machine. Its mutilated ducklike head held high, its colossal feet lifting one after the other in a heavy, slowing waddle, and its hoa.r.s.e screams re-echoing in a senseless uproar of agony.

Tommy's hands were shaking, but his brain was cool with a vast coolness. He raced past the shrieking monster, and halted in its path.

He saw Evelyn, a huddled bundle, clasped still to the creature's scaly breast. And Tommy sent a burst of explosive bullets into a gigantic, foot thick ankle-joint.

The monster toppled, and flung out its prehensile lizard claws in an instinctive effort to catch itself. Evelyn was thrown clear. And Tommy, standing alone in the blackness of a carboniferous jungle upon an alien planet, sent bullet after bullet into the shaking, obscenely flabby body of the thing. The bullets penetrated, and exploded. Great ma.s.ses of flesh upheaved and fell away. Great gouts of awful smelling fluid were flung out and blown to mist by the explosions. The thing did not so much die as disintegrate under the storm of detonating missiles.

Then Tommy went to Evelyn. He was wild with grief. He had no faintest hope that she could still be living. But as he picked her up she moaned softly, and when he cried her name she clung to him, pressing close in an agony of thankfulness almost as devastating as her fear had been.

It was minutes before either of them could think of anything other than her safety and the fact that they were together again. But then Tommy said, in a shaken effort to be himself again:

"I--I'd have done better if--if I'd had roller skates, maybe." His grin was wholly unconvincing. "Why'd you get out of the Tube?"

"Its eyes!" Evelyn shuddered, her own eyes hidden against Tommy's shoulder. "I saw them suddenly, looking at me. And I--hadn't any will.

I felt myself getting out of the Tube and walking toward it. It was like the way a snake fascinates--hypnotizes--a bird...."

A vagrant wind-eddy submerged them in the foul reek of the dead thing's flesh. Tommy stirred.

"Ugh! Let's get out of this. There'll be things coming to feed on that carca.s.s. They'll smell it."

Evelyn tried to stand, and succeeded. She clung to his hand.

"Do you think you can find the Tube again?"

Tommy was already thinking of that. He grimaced.

"Probably. Back-trail the d.a.m.ned thing. If the flashlight battery holds out. Its tail left plenty of sign for us to follow."

They started. And Evelyn had literally been forgotten in its agony by the monster which had carried her. Its body, though scaled and warty, was flabby and soft. Pressed against its breast she had been half strangled, but had no injuries beyond huge, purple bruises which had not yet reached the point of stiffness. She followed Tommy gamely, and the need for action kept her from yielding to the reaction from her terror.

For a long, long time they back-trailed. Less than fifteen minutes after leaving the carca.s.s of the thing Tommy had killed, they heard beast-roarings and the sound of fighting. But that noise died away as they traveled. Presently they reached the spot where Tommy had leaped upon a huge living thing. It was gone now, but the impress of a body the thickness of a barrel remained upon the rotted vegetation of the jungle floor. Evelyn shivered when Tommy pointed it out.
