"To whom do we bring these sacrifices?"

As the high priest uttered the words, and before the booming answer came, a hand grasped Ennis and pulled him back from the line of victims. He spun round to find that it was one of the other priests who had jerked him back.

"We bring them to Those Beyond the Door!"

As the colossal response thundered, the priest who had jerked Ennis back whispered urgently to him. "You go too close to the victims, Chandra Da.s.s! Do you wish to be taken with them?"

The fellow had a tight grip on Ennis' arm. Desperate, tensed, Ennis heard the chief priest roll forth the last of the ritual.

"Shall the Door be opened that They may take the sacrifices?"

Stunning, mighty, a tremendous shout that mingled in it wors.h.i.+pping awe and superhuman dread, the answer crashed back.

"Let the Door be opened!"

The chief priest turned and his up-flung arms whirled in a signal. Ennis, tensing to spring toward Ruth, saw the two priests at the gray mechanism swiftly turn the knurled black k.n.o.bs. Then Ennis, like all else in the vast cavern, was held frozen and spellbound by what followed.

The spherical web of wires pulsed up madly with s.h.i.+ning force. And up at the center of the gleaming black oval facet on the wall, there appeared a spark of unearthly green light. It blossomed outward, expanded, an awful viridescent flower blooming quickly outward farther and farther. And as it expanded, Ennis saw that he could look through that green light! He looked through into another universe, a universe lying infinitely far across alien dimensions from our own, yet one that could be reached through this door between dimensions. It was a green universe, flooded with an awful green light that was somehow more akin to darkness than to light, a throbbing, baleful luminescence.

Ennis saw dimly through green-lit s.p.a.ces a city in the near distance, an unholy city of emerald hue whose unsymmetrical, twisted towers and minarets aspired into heavens of h.e.l.lish viridity. The towers of that city swayed to and fro and writhed in the air. And Ennis saw that here and there in the soft green substance of that restless city were circles of lurid light that were like yellow eyes.

In ghastly, soul-shaking apprehension of the utterly alien, Ennis knew that the yellow circles were eyes--that that h.e.l.l-sp.a.w.ned city of another universe was living--that its unfamiliar life was single yet multiple, that its lurid eyes looked now through the Door!

Out from the insane living metropolis glided pseudopods of its green substance, glided toward the Door. Ennis saw that in the end of each pseudopod was one of the lurid eyes. He saw those eyed pseudopods come questing through the Door, onto the dais.

The yellow eyes of light seemed fixed on the row of stiff victims, and the pseudopods glided toward them. Through the open door was beating wave on wave of unfamiliar, tingling forces that Ennis felt even through the protective robe.

The hooded mult.i.tude bent in awe as the green pseudopods glided toward the victims faster, with avid eagerness. Ennis saw them reaching for the prisoners, for Ruth, and he made a tremendous mental effort to break the spell that froze him. In that moment pistol-shots crashed across the cavern and a stream of bullets smashed the pulsing web of wires!

The Door began instantly to close. Darkness crept back around the edges of the mighty oval. As though alarmed, the lurid-eyed pseudopods of that h.e.l.l-city recoiled from the victims, back through the dwindling Door. And as the Door dwindled, the light in the cavern was failing.

"Ruth!" yelled Ennis madly, and sprang forward and grasped her, his pistol leaping into his other hand.

"Ennis--quick!" shouted Campbell's voice across the cavern.

The Door dwindled away altogether; the great oval facet was completely black. The light was fast dying too.

The chief priest sprang madly toward Ennis, and as he did so, the hooded hordes of the Brotherhood recovered from their paralysis of horror and surged madly toward the dais.

"The Door is closed! Death to the blasphemers!" cried the chief priest as he plunged forward.

"Death to the blasphemers!" shrieked the crazed horde below.

Ennis' pistol roared and the chief priest went down. The light in the cavern died completely at that moment.

In the dark a torrent of bodies catapulted against Ennis, screaming vengeance. He struck out with his pistol-barrel in the mad melee, holding Ruth's stiff form close with his other hand. He heard the other drugged, helpless victims crushed down and trampled under foot by the surging horde of vengeance-mad members.

Clinging to the girl, Ennis fought like a madman through a darkness in which none could distinguish friend or foe, toward the door at the side from which Campbell had fired. He smashed down the pistol-barrel on all before him, as hands sought to grab him in the dark. He knew sickeningly that he was lost in the combat, with no sense of the direction of the door.

Then a voice roared loud across the wild din, "Ennis, this way! This way, Ennis!" yelled Inspector Campbell, again and again.

Ennis plunged through the whirl of unseen bodies in the direction of the detective's shouting voice. He smashed through, half dragging and half carrying the girl, until Campbell's voice was close ahead in the dark. He fumbled at the rock wall, found the door opening, and then Campbell's hands grasped him to pull him inside.

Hands grabbed him from behind, striving to tear Ruth from him, to jerk him back. Voices shrieked for help.

Campbell's pistol blazed in the dark and the hands released their grip. Ennis stumbled with the girl through the door into a dark tunnel. He heard Campbell slam a door shut, and heard a bar fall with a clang.

"Quick, for G.o.d's sake!" panted Campbell in the dark. "They'll follow us--we've got to get up through the tunnels to the water-cavern!"

They raced along the pitch-dark tunnel, Campbell now carrying the girl, Ennis reeling drunkenly along.

They heard a mounting roar behind them, and as they burst into the main tunnel, no longer lighted but dark like the others, they looked back and saw a flickering of light coming up the pa.s.sage.

"They're after us and they've got lights!" Campbell cried. "Hurry!"

It was nightmare, this mad flight on stumbling feet up through the dark tunnels where they could hear the sea booming close overhead, and could hear the wild pursuit behind.

Their feet slipped on the damp floor and they crashed into the walls of the tunnel at the turns. The pursuit was closer behind--as they started climbing the last pa.s.sages to the water-cavern, the torchlight behind showed them to their pursuers and wild yells came to their ears.

They had before them only the last ascent to the water-cavern when Ennis stumbled and went down. He swayed up a little, yelled to Campbell. "Go on--get Ruth out! I'll try to hold them back a moment!"

"No!" rasped Campbell. "There's another way--one that may mean the end for us too, but our only chance!"

The inspector thrust his hand into his pocket, s.n.a.t.c.hed out his big, old-fas.h.i.+oned gold watch.

He tore it from its chain, turned the stem of it twice around. Then he hurled it back down the tunnel with all his force.

"Quick--out of the tunnels now or we'll die right here!" he yelled.

They lunged forward, Campbell dragging both the girl and the exhausted Ennis, and emerged a moment later into the great water-cavern. It was now lit only by the searchlight of their waiting cutter.

As they emerged into the cavern, they were thrown flat on the rock ledge by a violent movement of it under them. An awful detonation and thunderous cras.h.i.+ng of falling rock smote their ears.

Following that first tremendous crash, giant rumbling of collapsing rock shook the water-cavern.

"To the cutter!" Campbell cried. "That watch of mine was filled with the most concentrated high-explosive known, and it's blown up the tunnels. Now it's touched off more collapses and all these caverns and pa.s.sages will fall in on us at any moment!"

The awful rumbling and cras.h.i.+ng of collapsing rock ma.s.ses was deafening in their ears as they lurched toward the cutter. Great chunks of rock were falling from the cavern roof into the water.

Sturt, white-faced but asking no questions, had the motor of the cutter running, and helped them pull the unconscious girl aboard.

"Out of the tunnel at once!" Campbell ordered. "Full speed!"

They roared down the water-tunnel at crazy velocity, the searchlight beam stabbing ahead. The tide had reached flood and turned, increasing the speed with which they dashed through the tunnel.

Ma.s.ses of rock fell with loud splashes behind them, and all around them was still the ominous grinding of mighty weights of rock. The walls of the tunnel quivered repeatedly.

Sturt suddenly reversed the propellers, but in spite of his action the cutter smashed a moment later into a solid rock wall. It was a ma.s.s of rock forming an unbroken barrier across the water-tunnel, extending beneath the surface of the water.

"We're trapped!" cried Sturt. "A ma.s.s of the rock has settled here and blocked the tunnel."

"It can't be completely blocked!" Campbell exclaimed. "See, the tide still runs out beneath it. Our one chance is to swim out under the blocking ma.s.s of rock, before the whole cliff gives way!"

"But there's no telling how far the block may extend----" Sturt cried.

Then as Campbell and Ennis stripped off their coats and shoes, he followed their example. The rumble of grinding rock around them was now continuous and nerve-shattering.

Campbell helped Ennis lower Ruth's unconscious form into the water.

"Keep your hand over her nose and mouth!" cried the inspector. "Come on, now!"

Sturt went first, his face pale in the searchlight beam as he dived under the rock ma.s.s. The tidal current carried him out of sight in a moment.

Then, holding the girl between them, and with Ennis' hand covering her mouth and nostrils, the other two dived. Down through the cold waters they shot, and then the swift current was carrying them forward like a mill-race, their bodies b.u.mping and sc.r.a.ping against the rock ma.s.s overhead.

Ennis' lungs began to burn, his brain to reel, as they rushed on in the waters, still holding the girl tightly. They struck solid rock, a wall across their way. The current sucked them downward, to a small opening at the bottom. They wedged in it, struggled fiercely, then tore through it. They rose on the other side of it into pure air. They were in the darkness, floating in the tunnel beyond the block, the current carrying them swiftly onward.

The walls were shaking and roaring frightfully about them as they were borne round the turns of the tunnel. Then they saw ahead of them a circle of dim light, p.r.i.c.ked with white stars.

The current bore them out into that starlight, into the open sea. Before them in the water floated Sturt, and they swam with him out from the shaking, grinding cliffs.

The girl stirred a little in Ennis' grasp, and he saw in the starlight that her face was no longer dazed.

"Paul----" she muttered, clinging close to Ennis in the water.

"She's coming back to consciousness--the water must have revived her from that drug!" he cried.

But he was cut short by Campbell's cry. "Look! Look!" cried the inspector, pointing back at the black cliffs.

In the starlight the whole cliff was collapsing, with a prolonged, terrible roar as of grinding planets, its face breaking and buckling. The waters around them boiled furiously, whirling them this way and that.

Then the waters quieted. They found they had been flung near a sandy spit beyond the shattered cliffs, and they swam toward it.

"The whole underground honeycomb of caverns and tunnels gave way and the sea poured in!" Campbell cried. "The Door, and the Brotherhood of the Door, are ended for ever!"

BEYOND THE THUNDER.

By H. B. Hickey

What was this blinding force that came out of a hole in the sky, and was powerful enough to destroy an entire city? Case thought he knew...

Ten thousand persons in New York looked skyward at the first rumble of sound. The flash caught them that way, seared them to cinder, liquefied their eyeb.a.l.l.s, brought their vitals boiling out of the fissures of their bodies. They were the lucky ones. The rest died slowly, their monument the rubble which had once been a city.

Of all that, Case Damon knew nothing. Rocketing up in the self-service elevator to his new cloud-reaching apartment in San Francisco, his thoughts were all on the girl who would be waiting for him.

"She loves me, she loves me not," he said to himself. They were orchid petals, not those of daisies, that drifted to the floor of the car.

"She loves me." The last one touched the floor softly, and Case laughed.

Then the doors were opening and he was racing down the hall. No more lonely nights for him, no more hours wasted thumbing through the pages of his little black book wondering which girl to call. Case Damon, rocket-jockey, s.p.a.ce-explorer, was now a married man, married to the most beautiful girl in the world.

He scooped Karin off her feet and hugged her to him. Her lips were red velvet on his, her spun gold hair drifted around his shoulders.

"Box seats for the best show in town, honey," he gloated in her ear.

He fished around in his pockets with one hand while he held her against him with the other. They'd said you couldn't get tickets for that show. But what "they" said never stopped Case Damon, whether it was a matter of theatre tickets, or of opening a new field on a distant airless planet.

"Turn off that telecast," he said. "I'm not interested in Interplan news these days. From now on, Case Damon keeps his feet on terra firma."

And that was the way it was going to be. His interest in the uranium on Trehos alone should keep him and Karin in clover for the rest of their lives. They'd have fun, they'd have kids, they'd live like normal married people. The rest of the universe could go hang.

"If you'd stop raving, I might get a word in edgewise," Karin begged.

"The floor is yours. Also the walls, the building, the whole darned city if you want it," Case laughed.

"That telecast is ticking for you. Was.h.i.+ngton calling Case Damon. Was.h.i.+ngton calling Case Damon. Since you left an hour ago it's been calling you."

"Let it call. It's my const.i.tutional right not to answer."

But his mood was changing to match Karin's. His lean, firm-jawed features were turning serious. Tension tightened his powerful body.

"It must be important, Case," Karin said. "They're using your code call. They wouldn't do that unless it was urgent."

He listened to the tick of the machine. Unless you knew, it sounded only like the regular ticking that told the machine was in operation. But there were little breaks here and there. It was for him.

Three long strides took him to the machine. His deft fingers flicked switches, brought a glow to the video tubes.

"Case Damon," he said softly. "Come in, Was.h.i.+ngton."

It was Cranly's face that filled the screen. But a Cranly Case barely recognized. The man had aged ten years in the last three days. His voice was desperate.
