Part 2

"That is right," he nodded. "Once the zone is complete it is a bubble--a nothingness--entirely apart from our Space and Time. The forces build up very rapidly, exponentially, but until the very instant of completion, even if it is one little billionth of a second before that moment, the zone will collapse if the power which builds it is shut off. Never in practice would one go so far. Long before it is complete, such a zone will repel all things that can be directed against it, while the balance of power still remains in the hands of him who has created it. To make it--that is nothing. To destroy it is impossible. But to hold it so in the delicate balance between destruction and completion; that is the triumph of Pierre Dampier! I have calculated it all from the equations. See--here at these red lines each needle must stop. If they go beyond--zut! In the space of a thinking the zone is complete! Beyond control!"

He straightened up, his wirey mop of hair bobbing at my shoulder. "Now, please, if you will watch and remember. The loops are set, so, for the sphere--little, like the apple of the eye. Now I press the first switch, and the second and then the others, three, and four, and five. Now I turn the dials, so, a little at a time. A minute now, while the zone builds, and then you will call Monsieur Porter and show him that this is not all sunshine and honeysuckers that he reads."

The big machine began to hum a deep-throated drone that deepened and strengthened until I could feel it shaking the floor under my feet with each colossal pulse of energy. I wondered about the sympathetic vibrations you read about in the Sunday supplements. Might it not shake the walls down around our ears? But Dampier didn't seem worried. And then I forgot it, for a shadow was beginning to form in the space between the coils.

That's all it was at first--a shadow, the size of a big red polished apple. I could hardly be sure it was there, but there was something queer about the way light acted that showed me where it was. Things behind it disappeared, smothered out by something that wasn't really darkness; and then suddenly it began to shine.

You've seen bubbles of air under water, shining like quicksilver. Well, it was like that. It was flawless, without texture, intangible and shimmering. It was not the thing itself we saw, but the things reflected in it--a little, twisted, shining world swimming in the heart of that ball of distorted space. Peering closer, I saw that the coils which shaped it were glowing with an eerie, frosty white light. I stared, fascinated, and by what? By a half-invisible bubble, like an indoor baseball, conjured up by some legerdemain to make fools of us! It was nonsense! I jerked my eyes away--and saw them.

Three men with guns stood on the little stair, watching us. They were gentlemen, polished, clever gentlemen adroit at the art of death. Their guns were of the kind which Middle-Europe gives to its officers, and their faces were Middle-European faces. They were in formal dress, and one of them held his gloves in his left hand.

Dampier had seen them before I, reflected in the shining sphere. He turned, his back against the control-panel, his white teeth gnawing like a rat's at his black beard. The madness was back in his glittering eyes; madness of a trapped beast.

"So!" he whispered. "Now we shall meet."

They came down the stairs, one after the other. How they had cut their way into that Gibraltar of a house I will never know. They may have been working for days and weeks to break through Dampier's defenses. But they were there.

Resistance was futile. Even Dampier realized that. The three guns urged us back against the wall. Deft fingers searched us but found nothing. The three men stepped back to the foot of the little stair, their guns raised, like a firing squad waiting for the signal. And then, above them, I saw the smiling face of Wilhelm Friedrich Nebel, Ambassador from Middle-Europe.

I hadn't believed Dampier's story until then. It was fantastic, this spy business, with a man like Nebel in the villain's role. Things like that don't happen any more. Yet Wilhelm Nebel stood there with a smile on his heavy lips and no smile at all in his pale little eyes. He came down the stairs, treading silently like a cat. He was like a cat in his black and white evening attire, white-bosomed and sleek. He had in his slender fingers a thick golden chain, with a heavy seal of gold made from an ancient coin. A crimson ribbon stretched across his breast like a line of blood.

Satan at the sacrifice! And then the illusion broke.

Those devil fingers went into the pocket of his vest, brought out thick, steel-rimmed spectacles, perched them precariously on the thin-bridged nose. The massive shoulders slouched over, trousers drew tight across his heavy buttocks as he bent and stared into the shining globe. I had never thought of Nebel as fat or gross, in spite of his size, but that single act showed him to me as a Teuton peddler, stooping to finger the weave of some shoddy cloth, to decide how high a price would be safe and how low a one profitable. Satan from his throne! He stood erect again, but his massive face was red with the effort.

Me he ignored. I was nobody. He bowed to Dampier and again I heard the cloth of his breeches creak.

"We meet again, Monsieur."

Dampier answered nothing. He too had his fine tradition of insolence. Nebel's slim hand flicked toward the machine. "This, I presume, is the great weapon that is to be the salvation of _la belle France_. This shining ball that floats in the empty air. Will you show us what it can do?"

The Frenchman's eyes never left Nebel's suave face as he went to the machine. His fingers darted here and there among the dials, tugging and twisting. Above his head the coils stirred in their massive bearings, and within their compass the silver sphere swelled like an inflating balloon to the size of a man's head--of a basketball--larger and larger while its shimmering surface took on a steely hardness. We seemed to be staring into unfathomable depths, out of which tiny distorted replicas of ourselves peered curiously. I had a feeling that I was two men, one here in this buried room and the other there in that twisted other room, staring inscrutably into my own eyes.

"Stop!" Nebel's voice rapped in my ears. The sphere was huge--ten feet and more in diameter. "It is large enough," he said. "What else will it do?"

I saw Dampier's eyes then. I knew that this time there would be no stopping him. Step by step I withdrew toward the wall. One of the guards saw me and turned his pistol to cover me, but made no other sign.

Dampier answered. "Many things, Monsieur. If you will watch--?" He pulled up his coat-sleeve, baring his scrawny arm, and clambering up on the platform pushed his hand and arm into the shining sphere. I saw the sweat come out on his forehead with the effort. Already the zone was strong. He withdrew his hand and touched the dials of the control-board. Nebel's eyes were watching every move, his hand in the pocket of his coat. Dampier stepped back. "If the gentlemen will shoot? But I warn you--be wary of the ricochet."

Nebel's finger jerked up. "Rudolf!" The youngest of the three men stepped forward and emptied his gun at the shining globe. The first bullet passed through and spanged against the farther wall; the rest glanced whining from its surface and bit ugly scars from the concrete wall beyond. Dampier's eyebrows raised ever so little.

"You have improved the quality of your guns," he commended. "They are more powerful than I had thought."

"Is that all?"

"Is it not enough? What weapon have your thieving swine stolen that will penetrate what you have seen?"

"Is that all?" Nebel's face was purple with rage. They hated each other bitterly, these two, and Dampier had given him not the slightest satisfaction as yet.

The Frenchman shrugged. "It is not complete. Nothing can pass the completed zone, though it is good enough now for anything your blundering fools have invented or will invent. However--"

He turned to the dials. Then suddenly he wheeled. His thin lips were drawn back in a snarl of fury, his eyes were sunken pools of black hate. With a scream he leapt at Nebel's throat.

The first slug caught him in mid-air. The shock dropped him in a crooked heap. Five more bullets smacked into him as he lay there, then Nebel's polished shoe went out and turned him over on his back. He lay there, a bloody froth on his contorted lips, sneering up at the man who had killed him.

For the first time Nebel turned to me. "It was in self defense. You will remember that, Mr. Crandall, if I decide to let you live." He went to the machine, as Dampier had done, and tapped the dials lightly with his long white fingers.

"These red marks--they are, I suppose, the settings with which Monsieur Dampier was working. He would not go beyond, for me. And yet, they are less than halfway to the limit of the dials. What will happen, if I turn them so--a hair beyond?"

His fingers twisted once, twice, and behind us Bill Porter's voice cried out. "Stop, you fool! Stop!"

He stood in the door of the temperature room, the sheaf of Dampier's notes in his hand. Nebel's thin eyebrows went up. "Mr. Porter! I had forgotten you. And why am I a fool?" His fingers spun another of the dials.

"You murdering Teuton fool!" Bill's tone was venomous. "What do you know about science? Your agents bring you this and that. You pay them or kill them, as may be convenient, but what do you know or care about what they have given you, so long as it can be sold at a profit: Mike, come here."

No one moved to stop me. Bill held out the papers, his thumbs marking a certain line. I saw that the margins were filled with his spidery writing.

"Take that top sheet. Now, look at those readings. Has he reached them yet?"

The figures looked familiar. Of course they were the settings at which Dampier had drawn his little red lines.

"He's past them," I cried. "On all but two."

"On all, my friend." Nebel turned again to the dials. "Bluffing does not work in a game for men."

As he moved Bill sprang. Not at Nebel--not at the machine--but at the two great copper bars that came in through the wall. His lean body fell like a stretched spear across them. There was a burst of flame, the stench of burning flesh, but my eyes had left him. For as he leaped Nebel turned the dials.

A roar of subterranean thunders shook the room. Vast energies poured into the shining zone. It changed. It was a great mirror of utter blackness, its shimmering silver sheen gone leaving a shell of strange transparency out of which creatures of another world leered crookedly at us. And it began to grow!

Momentum carried it. I know that now. The looped coils were swept aside. The apparatus beneath it buckled and split. Beyond it, Nebel's highborn gunmen gaped aghast. They vanished behind its sleek circumference, but Wilhelm Nebel was not of their stupid breed. With a roar he flung his huge body high across the swelling arc of the sphere's circumference. A moment he slithered on its top, sprawled like a toad, his great face crimson--then it crashed him against the ceiling like a toad under a giant's heel. Fragments of concrete began to fall.

I was up the stair, the remaining sheet of Dampier's equations in my hand. I was at the outer door as the walls buckled and fell in ruin. I was running across the littered lawn, staring over my shoulder at the giant silver globe that towered a hundred feet above me. Then it burst!

The force of the explosion hurled me a hundred yards across the fields. I lay gasping in the wet grass, staring glassy-eyed at the column of violet flame that plumed into the sky. I got shakily to my feet and stared into the smoking pit where Dampier's fortress had been. At last I remembered the scrap of crumpled paper in my hand.

The margins of Dampier's paper were full of Bill's penciled notes. At the end he had added five neat equations, and below them the remaining space was filled with his closely written lines.

"These added equations prove Dampier's analysis to be incomplete," he had written. "Such a totally reflecting zone has every characteristic of the closed, intangible boundary of the Einsteinian universe. It may be considered the boundary of such a universe in miniature, containing every force and body of the greater outside universe which it reflects. Neither is more real, in the physical sense, than the other. There is no way of disproving that we may not in turn be the images of some greater universe than ours, outside of the Einsteinian boundaries of our Space and Time.

"Jeans, and others, have postulated that the size of such a closed universe must depend upon the number of physical particles included in it, and that it will expand, _as our universe is expanding_, until that size is reached. Dampier's closed zone, containing the same number of image-particles as our own outside universe, must expand _to the same size_, and at a vastly greater rate.

"It may be that the cosmic atom, postulated by Abbe Lemaitre, from which our universe was born, was the creation of some Dampier of a super-universe, who failed to check its growth, and that its swelling bubble is crushing the mighty cosmos of which it is the ultimate image, as Dampier's completed zone would crush our own."

Bill Porter's scribbled notes stop there. In the split millionth of a second before the twist of Nebel's fingers could throw the balanced sphere over the boundary to completion, his body shorted the power that fed the great machine. It was in time! Momentum of growth, gained in that instant of which Dampier had told me, swept Nebel and his gunmen to their death, and as the zone collapsed the incalculable energies trapped in it burst forth in a holocaust of atomic flame. A millionth of a second--less perhaps--but in it chance, and whatever power it is that rules chance, had checked the thing whose illimitable growth would have swept our universe before it in an avalanche of destruction.

If, as Bill Porter thought, our universe is just such a swelling bubble in the vaster world which it mirrors, I wonder whether in that world there is not another Dampier, another Nebel, another Bill Porter going to his death. I wonder if Time itself is not reflected in some contorted scale in such a cosmic bubble, and the entire history of a universe reproduced in the instant before it bursts.

I wonder, too, if one day our bubble-universe will not burst as Dampier's did, robbing us in that future instant of all reality--the snuffed out images in an almost perfect mirror. For as our Dampier did, so did the greater Dampier whose image he was. As he failed so did that other Dampier fail. Perhaps, in his turn, he but mirrored greater things beyond. Where then--in what inconceivable realm beyond Space and Time--is the reality of which we are the ultimate image?
