"All right," he said quietly. "I can disguise you so you'll not be recognized. But you'll have to follow my orders exactly, or death will result for both of us."

That strange, hooded dread flickered again in his eyes, as though he saw through shrouding mists the outline of dim horror.

"It may be," he added slowly, "that something worse even than death awaits those who try to oppose the Brotherhood of the Door--something that would explain the unearthly, superhuman dread that enwraps the secret mysteries of the order. We're taking more than our lives in our hands, I think, in trying to unveil those mysteries, to regain your wife. But we've got to act quickly, at all costs. We've got to find her before the great gathering of the Brotherhood takes place, or we'll never find her."

Two hours before midnight found Campbell and Ennis pa.s.sing along a cobble-paved waterfront street north of the great East India Docks. Big warehouses towered black and silent in the darkness on one side, and on the other were old, rotting docks beyond which Ennis glimpsed the black water and gliding lights of the river.

As they straggled beneath the infrequent lights of the ill-lit street, they were utterly changed in appearance. Inspector Campbell, dressed in a shabby suit and rusty bowler, his dirty white s.h.i.+rt innocent of tie, had acquired a new face, a bright red, oily, eager one, and a high, squeaky voice. Ennis wore a rough blue seaman's jacket and a vizored cap pulled down over his head. His unshaven-looking face and subtly altered features made him seem a half-intoxicated seaman off his s.h.i.+p, as he stumbled unsteadily along. Campbell clung to him in true land-shark fas.h.i.+on, plucking his arm and talking wheedlingly to him.

They came into a more populous section of the evil old waterfront street, and pa.s.sed fried-fish shops giving off the strong smell of hot fat, and the dirty, lighted windows of a half-dozen waterfront saloons, loud with sordid argument or merriment.

Campbell led past them until they reached one built upon an abandoned, moldering pier, a ramshackle frame structure extending some distance back out on the pier. Its window was curtained, but dull red light glowed through the gla.s.s window of the door.

A few shabby men were lounging in front of the place but Campbell paid them no attention, tugging Ennis inside by the arm.

"Carm on in!" he wheedled shrilly. "The night ain't 'alf over yet--we'll 'ave just one more."

"Don't want any more," muttered Ennis drunkenly, swaying on his feet inside. "Get away, you d.a.m.ned old shark."

Yet he suffered himself to be led by Campbell to a table, where he slumped heavily into a chair. His stare swung vacantly.

The cafe of Chandra Da.s.s was a red-lit, smoke-filled cave with cheap black curtains on the walls and windows, and other curtains cutting off the back part of the building from view. The dim room was jammed with tables crowded with patrons whose babel of tongues made an unceasing din, to which a three-string guitar somewhere added a wailing undertone. The waiters were dark-skinned and tiger-footed Malays, while the patrons seemed drawn from every nation east and west.

Ennis' glazed eyes saw dandified Chinese from Limehouse and Pennyfields, dark little Levantins from Soho, rough-looking c.o.c.kneys in shabby caps, a few crazily laughing blacks. From sly white faces, taut brown ones and impa.s.sive yellow ones came a dozen different languages. The air was thick with queer food-smells and the acrid smoke.

Campbell had selected a table near the back curtain, and now stridently ordered one of the Malay waiters to bring gin. He leaned forward with an oily smile to the drunken-looking Ennis, and spoke to him in a wheedling undertone.

"Don't look for a minute, but that's Chandra Da.s.s over in the corner, and he's watching us," he said.

Ennis shook his clutching hand away. "d.a.m.ned old shark!" he muttered again.

He turned his swaying head slowly, letting his eyes rest a moment on the man in the corner. That man was looking straight at him.

Chandra Da.s.s was tall, dressed in spotless white from his shoes to the turban on his head. The white made his dark, impa.s.sive, aquiline face stand out in chiseled relief. His eyes were coal-black, large, coldly searching, as they met Ennis' bleared gaze.

Ennis felt a strange chill as he met those eyes. There was something alien and unhuman, something uncannily disturbing, behind the Hindoo's stare. He turned his gaze vacantly from Chandra Da.s.s to the black curtains at the rear, and then back to his companion.

The silent Malay waiter had brought the liquor, and Campbell pressed a gla.s.s toward his companion. "'Ere, matey, take this."

"Don't want it," muttered Ennis, pus.h.i.+ng it away. Still in the same mutter, he added, "If Ruth's here, she's somewhere in the back there. I'm going back and find out."

"Don't try it that way, for G.o.d's sake!" said Campbell in the wheedling undertone. "Chandra Da.s.s is still watching, and those Malays would be on you in a minute. Wait until I give the word.

"All right, then," Campbell added in a louder, injured tone. "If you don't want it, I'll drink it myself."

He tossed off the gla.s.s of gin and set the gla.s.s down on the table, looking at his drunken companion with righteous indignation.

"Think I'm tryin' to bilk yer, eh?" he added. "That's a fine way to treat a pal!"

He added in the coaxing lower tone, "All right, I'm going to try it. Be ready to move when I light my cigarette."

He fished a soiled package of Gold Flakes from his pocket and put one in his mouth. Ennis waited, every muscle taut.

The inspector, his red, oily face still injured in expression, struck a match to his cigarette. Almost at once there was a loud oath from one of the shabby loungers outside the front of the building, and the sound of angry voices and blows.

The patrons of Chandra Da.s.s looked toward the door, and one of the Malay waiters went hastily out to quiet the fight. But it grew swiftly, sounded in a moment like a small riot. Crash--someone was pushed through the front window. The excited patrons pressed toward the front. Chandra Da.s.s pushed through them, issuing quick orders to his servants.

For the time being the back of the cafe was deserted and unnoticed. Campbell sprang to his feet, and with Ennis close behind him, darted through the black curtains. They found themselves in a black corridor at the end of which a red bulb burned dimly. They could still hear the uproar.

Campbell's gun was in his hand, and the American's in his.

"We dare only stay here a few moments," the inspector cried. "Look in those rooms along the corridor here."

Ennis frantically tore open a door and peered into a dark room smelling of drugs. "Ruth!" he cried softly. "Ruth!"

2. Death Trap There was no answer. The light in the corridor behind him suddenly went out, plunging him into pitch-black darkness. He jumped back into the dark corridor, and as he did so, heard a sudden scuffle further along it.

"Campbell!" he exclaimed, lunging forward in the black pa.s.sageway. There was no answer.

He pitched forward through stygian obscurity, his hands searching ahead of him for the inspector. In the dark something whipped smoothly around his throat, tightened there like a slender, contracting tentacle.

Ennis tore frenziedly at the thing, which he felt to be a slender silken cord, but he could not loosen it. It was choking him. He tried to cry out again to Campbell, but his throat could not emit the sounds. He thrashed, twisted helplessly, hearing a loud roaring in his ears, consciousness receding. Then, dimly as though in a dream, Ennis was aware of being lowered to the floor, of being half carried and half dragged along. The constriction around his throat was gone and rapidly his brain began to clear. He opened his eyes.

He found himself lying on the floor of a room illuminated by a great hanging bra.s.s lamp of ornate design. The walls of the room were hung with rich, grotesquely worked red silk Indian draperies. His hands and feet were bound behind him, and beside him, tied in the same manner, lay Inspector Campbell. Over them stood Chandra Da.s.s and two of the Malay servants. The faces of the servants were tigerish in their menace, but Chandra Da.s.s' face was one of dark, impa.s.sive scorn.

"So you misguided fools thought you could deceive me so easily as that?" he said in a strong, vibrant voice. "Why, we knew hours ago that you, Inspector Campbell, and you, Mr. Ennis, were coming here tonight. We let you get this far only because it was evident that somehow you had learned too much about us, and that it would be best to let you come here and meet your deaths."

"Chandra Da.s.s, I've men outside," rasped Campbell. "If we don't come out, they'll come in after us."

The Hindoo's proud, dark face did not change its scorn. "They will not come in for a little while, inspector. By that time you two will be dead and we shall be gone with our captives. Yes, Mr. Ennis, your wife is one of those captives," he added to the prostrate young American. "It is too bad we cannot take you and the inspector to share her glorious destiny, but then our accommodations of transport are limited."

"Ruth here?" Ennis' face flamed at the words, and he raised himself a little from the floor on his elbows.

"Then you'll let her go if I pay you? I'll raise any amount, I'll do anything you ask, if you'll set her free."

"No amount of money in the world could buy her from the Brotherhood of the Door," answered Chandra Da.s.s steadily. "For she belongs now, not to us, but to They Beyond the Door. Within a few hours she and many others shall stand before the Door, and They Beyond the Door shall take them."

"What are you going to do to her?" cried Ennis. "What is this d.a.m.ned Door and who are They Beyond it?"

"I do not think that even if I told you, your little mind would be able to accept the mighty truth," Chandra Da.s.s said calmly. His coal-black eyes suddenly flashed with fanatic, frenetic light. "How could your poor, earth-bound little intelligences conceive the true nature of the Door and of those who dwell beyond it? Your puny brains would be stricken senseless by mere apprehension of them, They who are mighty and crafty and dreadful beyond anything on earth."

A cold wind from the alien unknown seemed to sweep the lamplit room with the Hindoo's pa.s.sionate words. Then that rapt, fanatic exaltation dropped from him as suddenly as it had come, and he spoke in his ordinary vibrant tones.

"But enough of this parley with blind worms of the dust. Bring the weights!"

The last words were addressed to the Malay servants, who sprang to a closet in the corner of the room.

Inspector Campbell said steadily, "If my men find us dead when they come in here, they'll leave none of you living."

Chandra Da.s.s did not even listen to him, but ordered the dark servants sharply, "Attach the weights!"

The Malays had brought from the closet two fifty-pound lead b.a.l.l.s, and now they proceeded quickly to tie these to the feet of the two men. Then one of them rolled back the brilliant red Indian rug from the rough pine floor. A square trap-door was disclosed, and at Chandra Da.s.s' order, it was swung upward and open.

Up through the open square came the sound of waves slap-slapping against the piles of the old pier, and the heavy odors of salt water and of rotting wood invaded the room.

"The water under this pier is twenty feet deep," Chandra Da.s.s told the two prisoners. "I regret to give you so easy a death, but there is no opportunity to take you to the fate you deserve."

Ennis, his skin crawling on his flesh, nevertheless spoke rapidly and as steadily as possible to the Hindoo.

"Listen, I don't ask you to let me go, but I'll do anything you want, let you kill me any way you want, if you'll let Ruth----"

Sheer horror cut short his words. The Malay servants had dragged Campbell's bound body to the door in the floor. They shoved him over the edge. Ennis had one glimpse of the inspector's taut, strange face falling out of sight. Then a dull splash sounded instantly below, and then silence.

He felt hands upon himself, dragging him across the floor. He fought, crazily, hopelessly, twisting his body in its bonds, thras.h.i.+ng his bound limbs wildly.

[Ill.u.s.tration: "A shove sent his body sc.r.a.ping over the edge, and he plunged downward through dank darkness."]

He saw the dark, unmoved face of Chandra Da.s.s, the bra.s.s lamp over his head, the red hangings. Then his head dangled over the opening, a shove sent his body sc.r.a.ping over the edge, and he plunged downward through dank darkness. With a splash he hit the icy water and went under. The heavy weight at his ankles dragged him irresistibly downward. Instinctively he held his breath as the water rushed upward around him.

His feet struck oozy bottom. His body swayed there, chained by the lead weight to the bottom. His lungs already were bursting to draw in air, slow fires seeming to creep through his breast as he held his breath.

Ennis knew that in a moment or two more he would inhale the strangling waters and die. The thought-picture of Ruth flashed across his despairing mind, wild with hopeless regret. He could no longer hold his breath, felt his muscles relaxing against his will, tasted the stinging salt water at the back of his nose.

Then it was a bursting confusion of swift sensations, the choking water in his nose and throat, the roaring in his ears. A scroll of flame unrolled slowly in his brain and a voice shouted there, "You're dying!" He felt dimly a plucking at his ankles.

Abruptly Ennis' dimming mind was aware that he now was shooting upward through the water. His head burst into open air and he choked, strangled and gasped, his tortured lungs gulping the damp, heavy air. He opened his eyes, and shook the water from them.

He was floating in the darkness at the surface of the water. Someone was floating beside him, supporting him. Ennis' chin b.u.mped the other's shoulder, and he heard a familiar voice.

"Easy, now," said Inspector Campbell. "Wait till I cut your hands loose."

"Campbell!" Ennis choked. "How did you get loose?"

"Never mind that now," the inspector answered. "Don't make any noise, or they may hear us up there."

Ennis felt a knife-blade slas.h.i.+ng the bonds at his wrists. Then, the inspector's arm helping him, he and his companion paddled weakly through the darkness under the rotting pier. They b.u.mped against the slimy, moldering piles, threaded through them toward the side of the pier. The waves of the flooding tide washed them up and down as Campbell led the way.

They pa.s.sed out from under the old pier into the comparative illumination of the stars. Looking back up, Ennis saw the long, black ma.s.s of the house of Chandra Da.s.s, resting on the black pier, ruddy light glowing from window-cracks. He collided with something and found that Campbell had led toward a little floating dock where some skiffs were moored. They scrambled up onto it from the water, and lay panting for a few moments.

Campbell had something in his hand, a thin, razor-edged steel blade several inches long. Its hilt was an ordinary leather shoe-heel.

The inspector turned up one of his feet and Ennis saw that the heel was missing from that shoe. Carefully Campbell slid the steel blade beneath the shoe-sole, the heel-hilt sliding into place and seeming merely the innocent heel of the shoe.

"So that's how you got loose down in the water!" Ennis exclaimed, and the inspector nodded briefly.

"That trick's done me good service before--even with your hands tied behind your back you can get out that knife and use it. It was touch and go, though, whether I could get it out and cut myself loose in the water in time enough to free you."

Ennis gripped the inspector's shoulder. "Campbell, Ruth is in there! By heaven, we've found her and now we can get her out!"

"Right!" said the officer grimly. "We'll go around to the front and in two minutes we'll be in there with my men."

They climbed dripping to their feet, and hastened from the little floating dock up onto the sh.o.r.e, through the darkness to the cobbled street.

The shabbily disguised men of Inspector Campbell were not now in front of Chandra Da.s.s' cafe, but lurking in the shadows across the street. They came running toward Campbell and Ennis.

"All right, we're going in there," Campbell exclaimed in steely tones. "Get Chandra Da.s.s, whatever you do, but see that his prisoners are not harmed."

He snapped a word and one of the men handed pistols to him and to Ennis. Then they leaped toward the door of the Hindoo's cafe, from which still streamed ruddy light and the babel of many voices.

A kick from Inspector Campbell sent the door flying inward, and they burst in with guns gleaming wickedly in the ruddy light. Ennis' face was a quivering mask of desperate resolve.

The motley patrons jumped up with yells of alarm at their entrance. The hand of a Malay waiter jerked and a thrown knife thudded into the wall beside them. Ennis yelled as he saw Chandra Da.s.s, his dark face startled, leaping back with his servants through the black curtains.

He and Campbell drove through the squealing patrons toward the back. The Malay who had thrown the knife rushed to bar the way, another dagger uplifted. Campbell's gun coughed and the Malay reeled and stumbled. The inspector and Ennis threw themselves at the black curtains--and were dashed back.

They tore aside the black folds. A dull steel door had been lowered behind them, barring the way to the back rooms. Ennis beat crazily upon it with his pistol-b.u.t.t, but it remained immovable.

"No use--we can't break that down!" yelled Campbell, over the uproar. "Outside, and around to the other end of the building!"

They burst back out through that mad-house, into the dark of the street. They started along the side of the pier toward the river-end, edging forward on a narrow ledge but inches wide. As they reached the back of the building, Ennis shouted and pointed to dark figures at the end of the pier. There were two of them, lowering shapeless, wrapped forms over the end of the pier.

"There they are!" he cried. "They've got their prisoners out there with them."

Campbell's pistol leveled, but Ennis swiftly struck it up. "No, you might hit Ruth."

He and the inspector bounded forward along the pier. Fire streaked from the dark ahead and bullets thumped the rotting boards around them.

Suddenly the loud roar of an accelerated motor drowned out all other sounds. It came from the river at the pier's end.

Campbell and Ennis reached the end in time to see a long, powerful, gray motor-boat dash out into the black obscurity of the river, and roar eastward with gathering speed.

"There they go--they're getting away!" cried the agonized young American.

Inspector Campbell cupped his hands and shouted out into the darkness, "River police, ahoy! Ahoy there!"

He rasped to Ennis. "The river police were to have a cutter here tonight. We can still catch them."

With swiftly rising roar of speeded motors, a big cutter drove in from the darkness. Its searchlight snapped on, bathing the two men on the pier in a blinding glare.

"Ahoy, there!" called a stentorian voice over the roar of the motors. "Is that Inspector Campbell?"

"Yes. Come alongside," yelled the inspector, and as the big cutter shot close to the end of the pier, its reversing propellers churning the dark water to foam, Ennis and Campbell leaped.
