Tommy watched Smithers drive away. The sun was sinking low toward the west, and the car stirred up a cloud of light-encarmined dust as it sped down the long, narrow lane to the main road. The laboratory had intentionally been built in an isolated spot, but at the moment Tommy would have given a good deal for a few men nearby. Smithers was taking Von Holtz to Albany to add his information to Denham’s pleas. Denham had ordered it, when they reached him by phone after hours of effort. Smithers had to go, to guard against Von Holtz’s escape, even sick and ill as he was. And Evelyn had refused to go with him.

“If I stay in the laboratory,” she insisted fiercely, “you can slip down and I can blow up the Tube after you, if the Ragged Men don’t stay away. But by yourself….”

Tommy did not consent, but he was helpless. There was danger from the Tube. Not only from ghastly animals which might come through, but from men. Smithers had fought the Ragged Men above it. He had chased them off, but they would come back. Perhaps they would come very soon, perhaps not until Denham and Smithers had returned. If they could be held off, the as yet unknown dangers from the other Tube—of which only the lizards and the Death Mist were certainties—might be counteracted. In any case, the Tube must not be destroyed until its defense was hopeless.

Tommy made up a grim bundle to go through the Tube with him: the sub-machine gun, extra drums of shells, more gas bombs and half a dozen grenades. He hung the various objects about himself. Evelyn watched him miserably.

“You—you’ll be careful, Tommy?”

“Nothing else but,” said Tommy. He grinned reassuringly. “There’s nothing to it, really. Just sitting still, listening. If I pop off some fireworks I’ll just have to sit down and watch them run.”

He settled his gas mask about his neck and started to enter the Tube. Evelyn touched his arm.

“I’m—frightened, Tommy.”

“Shucks!” said Tommy. “Also a couple of tut-tuts.” He stood up, put his arms about her, and kissed her until she smiled. “Feel better now?” he asked interestedly.

“Y-yes….”

“Fine!” said Tommy, and grinned again. “When you feel scared again, ring me on the phone and I’ll give you another treatment.”

But her smile faded as, beaming at her, he crawled into the first section of the Tube. And his own expression grew serious enough when she could see him no longer. The situation was not comfortable. Evelyn intended to marry him and he had to keep her cheerful, but he wished she were well away from here.

He tried to move cautiously through the Tube, but his bundles bumped and rattled. It seemed hours before he was climbing up the last section into the tree-fern jungle. He was caution itself as he peered over the edge. It was already night upon Earth, but here the monstrous, dull-red sun was barely sinking. It moved slowly along the horizon as it dipped, but presently a gray cast come over the colorings in the forest. Flying things came clattering homeward through the masses of fern-fronds overhead. He saw a projectile-like thing with a lizard’s head and jaws go darting through an incredibly small opening. It seemed to have no wings at all. But then, in one instant, a vast wing-surface flashed out, made a single gigantic flap—and the thing was a projectile again, darting through a cheraux-de-frise of interlaced fronds without a sign of wings to support it.

Tommy inspected his surroundings with an infinite care. As the darkness deepened he meditatively taped a flashlight below the barrel of the sub-machine gun. Turned on, it would cast a pitiless light upon his target, and the sights would be silhouetted against the thing to be killed. He hung his grenades in a handy row just inside the mouth of the Tube and set his gas bombs conveniently in place, then settled down to watch.

It was assuredly necessary. Von Holtz’s story confirmed his own and Denham’s guesses and made their worst fears seem optimistic. Von Holtz had made a Tube for Jacaro, working from the model of Tommy’s own construction. It had been completed nearly a month before. But no jungle odors had seeped through that other Tube on its completion. It opened in a sub-cellar of a structure in the Golden City itself, the city of towers and soaring spires Denham had glimpsed long months before. By sheer fortune it opened upon a rarely used storeroom where improbable small animals—the equivalent of rats—played obscenely in the light of ever-glowing panels in the wall.

For two days of the Fifth-Dimension world Jacaro and his gunmen lay quiet. During two nights they made infinitely cautious reconnaissance. The second night it was necessary to kill two men who sighted the tiny exploring party. But the killing was done with silenced automatics, and there was no alarm. The third night they lay still, fearing an ambush. The fourth night Jacaro struck.

He and his men fled back to their Tube with plunder and precious gems. Their loot was vast even beyond their hopes, though they had killed other men in gathering it. The Golden City was rich beyond belief. The very crust of the Fifth-Dimension world seemed to be composed of other substances than those of Earth. The common metals of Earth were rare or even unknown. The rarer metals of Earth were the commonplace ones in the Golden City. Even the roofs seemed plated with gold, but Jacaro’s gunmen saw not one particle of iron save in a ring they took from a dead man’s finger. There, an acid-etched plate of steel was set as if to be used for a signet.

Von Holtz had accompanied the raiders perforce on every journey. Jeweled bearings for motors; objects of commonest use, made of gold beat thin for lightness; huge ingots of silver for industry; once a queer-shaped spool of platinum wire that it took two men to carry—these things made up the loot they scurried back to their rathole with. Five raids they made, and twenty men they shot down before they came upon disaster. On the sixth raid an outcry rose and an ambush fell upon them.

Flashes of incredibly vivid actinic flame leaped from queer engines that opened upon them. Curious small truncheonlike weapons spat paralyzing electric shocks upon them. The twelve gangsters fought with the desperation of cornered rats, with notched and explosive bullets and with streams of lead from tommy-guns.

A chance bullet blew something up. One of the flame weapons flew to bits, spouting what seemed to be liquid thermit upon friend and foe alike. The way of the gangsters back to their Tube was barred. The route they knew was a chaos of scorched bodies and melting metal. The thermit flowed in all directions, seeming to grow in volume as it flamed. Jacaro and his gangsters fled. They broke through the shaken remnants of the ambush. The six of them who survived the fighting found a man somnolently driving a ground vehicle with two wheels. They burst upon him and, with their scared faces constituting threats in themselves, forced him to drive them out of the Golden City. They fled along aluminum roads into the tree-fern forests, while the sky behind them seemed to flame as the city woke to the tumult in its ways.

They killed the driver of their vehicle when he refused to take them farther, and it was that murder which saved their lives. It was seen by Ragged Men, the outlaws of the jungle, and it proved their enmity to the Golden City. The Ragged Men greeted them joyously and fed them, and enlisted their aid in a savage attack on a land-convoy on the way to the city. Their weapons carried the convoy, and they watched wounded prisoners killed with excruciating tortures….

They were with the Ragged Men now, Von Holtz believed. He had fled a week or more before, when Jacaro—already learning the language of his half-mad allies—began to plan a grandiose attack upon the Golden City. Von Holtz was born a coward, and he knew where Tommy Reames and Denham would shortly thrust a Tube through. It would come out just where the catapult had flung Evelyn and Denham, months before, the same spot where he had marooned them. He searched desperately for that Tube, and failed to find it. He was chased by carnivores, scratched by thorns, and at last pursued by a yelling horde of human devils who were fired into by Smithers from the mouth of the just-finished Tube.

Tommy debated the story grimly as he stood guard in the Tube in the humid jungle night. Many-colored stars winked fitfully through the thatch of giant ferns overhead. The wind soughed unsteadily above the jungle. There were queer creakings, and once or twice there were distant cries, and when the wind died down there was a deep-toned croaking audible somewhere which sounded rather like the croaking of unthinkably, monstrous frogs. But it could not be that, of course. And once there was the sound of dainty movement and something passed nearby. Tommy Reames saw the shadowy outline of a bulk so vast that it turned him cold to think about it, and it did not seem fair for any creature as huge as that to move so quietly.

Then there was a little scuffling noise beneath him. A hand touched his foot.

“It’s—it’s me, Tommy.” Evelyn crowded up beside him and whispered shakenly: “It—it was so lonesome down there, so quiet.”

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 assured 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 bump 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 hell. 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 mass 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 hoarsely 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.
