He made a gesture to the two hooded men with pistols, and they ranged themselves close behind Campbell and Ennis.
"We are going to the Cavern of the Door," said the Hindoo. "Inspector Campbell, I know and respect your resourcefulness. Be warned that your slightest attempt to escape means a bullet in your back. You two will march ahead of us," he said, and added mockingly, "Remember, while you live you can cling to the shadow of hope, but if these guns speak, it ends even that shadow."
Ennis and Inspector Campbell, keeping their hands elevated, started at the Hindoo's command down the softly lit rock tunnel. Chandra Dass and the two hooded men with pistols followed.
Ennis saw that the inspector's sagging face was expressionless, and knew that behind that colorless mask, Campbell's brain was racing in an attempt to find a method of escape. For himself, the young American had almost forgotten all else in his eagerness to reach his wife. Whatever happened to Ruth, whatever mysterious horror lay in wait for her and the other victims, he would be there beside her, sharing it!
The tunnel wound a little further downward, then straightened out and ran straight for a considerable length. In this straight section of the rock passage, Ennis and Campbell for the first time perceived that the walls of the tunnel bore crowding, deeply chiseled inscriptions. They had not time to read them in passing, but Ennis saw that they were in many different languages, and that some of the characters were wholly unfamiliar.
"God, some of those inscriptions are in Egyptian hieroglyphics!" muttered Inspector Campbell.
The cool voice of Chandra Dass said, behind them, "There are pre-Egyptian inscriptions on these walls, inspector, could you but recognize them, carven in languages that perished from the face of earth before Egypt was born. Yes, back through time, back through mediæval and Roman and Egyptian and pre-Egyptian ages, the Brotherhood of the Door has existed and has each year gathered in this place to open the Door and worship with sacrifices They Beyond it."
The fanatic note of unearthly devotion was in his voice now, and Ennis shuddered with a cold not of the tunnel.
As they proceeded, they heard a muffled, hoarse booming somewhere over their heads, a dull, rhythmic thunder that echoed along the long passageway. The walls of the tunnel now were damp and glistening in the sourceless soft light, tiny trickles running down them.
"You hear the ocean over us," came Chandra Dass' voice. "The Cavern of the Door lies several hundred yards out from shore, beneath the rock floor of the sea."
They passed the dark mouths of unlit tunnels branching ahead from this illuminated one. Then over the booming of the raging sea above them, there came to Ennis' ears the distant, swelling chant they had heard in the water-cavern above. But now it was louder, nearer. At the sound of it, Chandra Dass quickened their pace.
Suddenly Inspector Campbell stumbled on the slippery rock floor and went down in a heap. Instantly Chandra Dass and his two followers recoiled from them, the two pistols trained on the detective as he scrambled up.
"Do not do that again, inspector," warned the Hindoo in a deadly voice. "All tricks are useless now."
"I couldn't help slipping on this wet floor," complained Inspector Campbell.
"The next time you make a wrong step of any kind, a bullet will smash your spine," Chandra Dass told him. "Quick--march!"

The tunnel turned sharply, turned again. As they rounded the turns, Ennis saw with a sudden electric thrill of hope that Campbell held clutched in his hand, concealed by his sleeve, the heel-hilted knife from his shoe. He had drawn it when he stumbled.
Campbell edged a little closer to the young American as they were hastening onward, and whispered to him, a word at a time.
"Be--ready--to jump--them----"
"But they'll shoot, your first move----" whispered Ennis agonizedly.
Campbell did not answer. But Ennis sensed the detective's body tautening.
They came to another turn, the strong, swelling chant coming loud from ahead. They started around that turn.
Then Inspector Campbell acted. He whirled as though on a pivot, the heel-knife flashing toward the men behind them.
Shots coughed from the pistols that were pressed almost against his stomach. His body jerked as the bullets struck it, yet he remained erect, his knife stabbing with lightning rapidity.
One of the hooded men slumped down with a pierced throat, and as Campbell sprang at the other, Ennis desperately launched himself at Chandra Dass. He bore the Hindoo from his feet, but it was as though he was fighting a demon. Inside his gray robe, Chandra Dass writhed with fiendish strength.
Ennis could not hold him, the Hindoo's body seeming of spring-steel. He rolled over, dashed the young American to the floor, and leaped up, his dark face and great black eyes blazing.
Then, half-way erect, he suddenly crumpled, the fire in his eyes dulling, a call for help smothered on his lips. He fell on his face, and Ennis saw that the heel-knife was stuck in his back. Inspector Campbell jerked it out, and put it back into his shoe. And now Ennis, staggering up, saw that Campbell had knifed the two hooded guards and that they lay in a dead heap.
"Campbell!" cried the American, gripping the detective's arm. "They've wounded you--I saw them shoot you."
Campbell's bruised face grinned briefly. "Nothing of the kind," he said, and tapped the soiled gray vest he wore beneath his coat. "Chandra Dass didn't know this vest is bullet-proof."
He darted an alert glance up and down the lighted tunnel. "We can't stay here or let these bodies lie here. They may be discovered at any moment."
"Listen!" said Ennis, turning.
The chanting from ahead swelled down the tunnel, louder than at any time yet, waxing and waxing, reaching a triumphant crescendo, then again dying away.
"Campbell, they're going on with the ceremony now!" Ennis cried. "Ruth!"
The detective's desperate glance fastened on the dark mouth of one of the branching tunnels, a little ahead.
"That side tunnel--we'll pull the bodies in there!" he exclaimed.
Taking the pistols of the dead men for themselves, they rapidly dragged the three bodies into the darkness of the unlit branching tunnel.
"Quick, on with two of these robes," rasped Inspector Campbell. "They'll give us a little better chance."
Hastily Ennis jerked the gray robe and hood from Chandra Dass' dead body and donned it, while Campbell struggled into one of the others. In the robes and concealing hoods, they could not be told from any other two members of the Brotherhood, except that the badge on Ennis' breast was the double star instead of the single one.
Ennis then spun toward the main, lighted tunnel, Campbell close behind him. They recoiled suddenly into the darkness of the branching way, as they heard hurrying steps out in the lighted passage. Flattened in the darkness against the wall, they saw several of the gray-hooded members of the Brotherhood hasten past them from above, hurrying toward the gathering-place.
"The guards and robe-issuers we saw above!" Campbell said quickly when they were passed. "Come on, now."
He and Ennis slipped out into the lighted tunnel and hastened along it after the others.
Boom of thundering ocean over their heads and rising and falling of the tremendous chanting ahead filled their ears as they hurried around the last turns of the tunnel. The passage widened, and ahead they saw a massive rock portal through whose opening they glimpsed an immense, lighted space.
Campbell and Ennis, two comparatively tiny gray-hooded figures, hastened through the mighty portal. Then they stopped. Ennis felt frozen with the dazing shock of it. He heard the detective whisper fiercely beside him.
"It's the Cavern, all right--the Cavern of the Door!"
* * * * *
They looked across a colossal rock chamber hollowed out beneath the floor of ocean. It was elliptical in shape, three hundred feet by its longer axis. Its black basalt sides, towering, rough-hewn walls, rose sheer and supported the rock ceiling which was the ocean floor, a
hundred feet over their heads.
This mighty cathedral hewn from inside the rock of earth was lit by a soft, white, sourceless light like that in the main tunnel. Upon the floor of the cavern, in regular rows across it, stood hundreds on hundreds of human figures, all gray-robed and gray-hooded, all with their backs to Campbell and Ennis, looking across the cavern to its farther end. At that farther end was a flat dais of black basalt upon which stood five hooded men, four wearing the blazing double-star on their breasts, the fifth, a triple-star. Two of them stood beside a cubical, weird-looking gray metal mechanism from which upreared a spherical web of countless fine wires, unthinkably intricate in their network, many of them pulsing with glowing force. The sourceless light of the cavern and the tunnel seemed to pulse from that weird mechanism.
Up from that machine, if machine it was, soared the black basalt wall of that end of the cavern. But there above the gray mechanism the rough wall had been carved with a great, smooth facet, a giant, gleaming black oval face as smooth as though planed and polished. Only, at the middle of the glistening black oval face, were carven deeply four large and wholly unfamiliar characters. As Ennis and Campbell stared frozenly across the awe-inspiring place, sound swelled from the hundreds of throats. A slow, rising chant, it climbed and climbed until the basalt roof above seemed to quiver to it, crashing out with stupendous effect, a weird litany in an unknown tongue. Then it began to fall.
Ennis clutched the inspector's gray-robed arm. "Where's Ruth?" he whispered frantically. "I don't see any prisoners."
"They must be somewhere here," Campbell said swiftly. "Listen----"
As the chant died to silence, on the dais at the farther end of the cavern the hooded man who wore the triple-jeweled star stepped forward and spoke. His deep, heavy voice rolled out and echoed across the cavern, flung back and forth from wall to rocky wall.
"Brothers of the Door," he said, "we meet again here in the Cavern of the Door this year, as for ten thousand years past our forefathers have met here to worship They Beyond the Door, and bring them the sacrifices They love.
"A hundred centuries have gone by since first They Beyond the Door sent their wisdom through the barrier between their universe and ours, a barrier which even They could not open from their side, but which their wisdom taught our fathers how to open.
"Each year since then have we opened the Door which They taught us how to build. Each year we have brought them sacrifices. And in return They have given us of their wisdom and power. They have taught us things that lie hidden from other men, and They have given us powers that other men have not.
"Now again comes the time appointed for the opening of the Door. In their universe on the other side of it, They are waiting now to take the sacrifices which we have procured for them. The hour strikes, so let the sacrifices be brought."
As though at a signal, from a small opening at one side of the cavern a triple file of marchers entered. A file of hooded gray members of the Brotherhood flanked on either side a line of men and women who did not wear the hoods or robes. They were thirty or forty in number. These men and women were of almost all races and classes, but all of them walked stiffly, mechanically, staring ahead with unseeing, distended eyes, like living corpses.
"Drugged!" came Campbell's shaken voice. "They're all drugged, and don't know what is going on."
Ennis' eyes fastened on a small, slender girl with chestnut hair who walked at the end of the line, a girl in a straight tan dress, whose face was white, stiff, like those of the others.
"There's Ruth!" he exclaimed frantically, his cry muffled by his hood.
He plunged in that direction, but Campbell held him back.
"No!" rasped the inspector. "You can't help her by simply getting yourself captured!"
"I can at least go with her!" Ennis exclaimed. "Let me go!"
Inspector Campbell's iron grip held him. "Wait, Ennis!" said the detective. "You've no chance that way. That robe of Chandra Dass' you're wearing has a double-star badge like those of the men up there on the dais. That means that as Chandra Dass you're entitled to be up there with them. Go up there and take your place as though you were Chandra Dass--with the hood on, they can't tell the difference. I'll slip around to that side door out of which they brought the prisoners. It must connect with the tunnels, and it's not far from the dais. When I fire my pistol from there, you grab your wife and try to get to that door with her. If you can do it, we'll have a chance to get up through the tunnels and escape."
Ennis wrung the inspector's hand. Then, without further reply, he walked boldly with measured steps up the main aisle of the cavern, through the gray ranks to the dais. He stepped up onto it, his heart racing. The chief priest, he of the triple-star, gave him only a glance, as of annoyance at his lateness. Ennis saw Campbell's gray figure slipping round to the side door.
The gray-hooded hundreds before him had paid no attention to either of them. Their attention was utterly, eagerly, fixed upon the stiff-moving prisoners now being marched up onto the dais. Ennis saw Ruth pass him, her white face an unfamiliar, staring mask.
The prisoners were ranged at the back of the dais, just beneath the great, gleaming black oval facet. The guards stepped back from them, and they remained standing stiffly there. Ennis edged a little toward Ruth, who stood at the end of that line of stiff figures. As he moved imperceptibly closer to her, he saw the two priests beside the gray mechanism reaching toward knurled knobs of ebonite affixed to its side, beneath the spherical web of pulsing wires.
The chief priest, at the front of the dais, raised his hands. His voice rolled out, heavy, commanding, reverberating again through all the cavern.
5. The Door Opens
"Where leads the Door?" rolled the chief priest's voice.
Back up to him came the reply of hundreds of voices, muffled by the hoods but loud, echoing to the roof of the cavern in a thunderous response.
"It leads outside our world!"
The chief priest waited until the echoes died before his deep voice rolled on in the ritual.
"Who taught our forefathers to open the Door?"
Ennis, edging desperately closer and closer to the line of victims, felt the mighty response reverberate about him.
"They Beyond the Door taught them!"
Now Ennis was apart from the other priests on the dais, within a few yards of the captives, of the small figure of Ruth.
"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 Dass! 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 worshipping 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 knobs. 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 shining 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 thro
ugh 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 spaces a city in the near distance, an unholy city of emerald hue whose unsymmetrical, twisted towers and minarets aspired into heavens of hellish 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 hell-spawned 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 multitude 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 hell-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.
