Part 8

As he looked, swift footsteps sounded and a man appeared suddenly in the doorway--a man disheveled, tattered and bloody. _John Gordon!_ Kathulos sprang erect with a cry, and Gordon, gasping as from superhuman exertion, brought down the revolver he held in his hand and fired point-blank. Kathulos staggered, clapping his hand to his breast, and then, groping wildly, reeled to the wall and fell against it. A doorway opened and he reeled through, but as Gordon leaped fiercely across the chamber, a blank stone surface met his gaze, which yielded not to his savage hammerings.

He whirled and ran drunkenly to the table where lay a bunch of keys the Master had dropped there.

"The vial!" I shrieked. "Take the vial!" And he thrust it into his pocket.

Back along the corridor through which he had come sounded a faint clamor growing swiftly like a wolf-pack in full cry. A few precious seconds spent with fumbling for the right key, then the cage door swung open and I sprang out. A sight for the gods we were, the two of us! Slashed, bruised and cut, our garments hanging in tatters--my wounds had ceased to bleed, but now as I moved they began again, and from the stiffness of my hands I knew that my knuckles were shattered. As for Gordon, he was fairly drenched in blood from crown to foot.

* * * * *

We made off down a passage in the opposite direction from the menacing noise, which I knew to be the black servants of the Master in full pursuit of us. Neither of us was in good shape for running, but we did our best. Where we were going I had no idea. My superhuman strength had deserted me and I was going now on will-power alone. We switched off into another corridor and we had not gone twenty steps until, looking back, I saw the first of the black devils round the corner.

A desperate effort increased our lead a trifle. But they had seen us, were in full view now, and a yell of fury broke from them to be succeeded by a more sinister silence as they bent all efforts to overhauling us.

There a short distance in front of us we saw a stair loom suddenly in the gloom. If we might reach that--but we saw something else.

Against the ceiling, between us and the stairs, hung a huge thing like an iron grill, with great spikes along the bottom--a portcullis. And even as we looked, without halting in our panting strides, it began to move.

"They're lowering the portcullis!" Gordon croaked, his blood-streaked face a mask of exhaustion and will.

Now the blacks were only ten feet behind us--now the huge grate, gaining momentum, with a creak of rusty, unused mechanism, rushed downward. A final spurt, a gasping straining nightmare of effort--and Gordon, sweeping us both along in a wild burst of pure nerve-strength, hurled us under and through, and the grate crashed behind us!

A moment we lay gasping, not heeding the frenzied horde who raved and screamed on the other side of the grate. So close had that final leap been, that the great spikes in their descent had torn shreds from our clothing.

The blacks were thrusting at us with daggers through the bars, but we were out of reach and it seemed to me that I was content to lie there and die of exhaustion. But Gordon weaved unsteadily erect and hauled me with him.

"Got to get out," he croaked; "got to warn--Scotland Yard--honeycombs in heart of London--high explosives--arms--ammunition."

We blundered up the steps, and in front of us I seemed to hear a sound of metal grating against metal. The stairs ended abruptly, on a landing that terminated in a blank wall. Gordon hammered against this and the inevitable secret doorway opened. Light streamed in, through the bars of a sort of grille. Men in the uniform of London police were sawing at these with hacksaws, and even as they greeted us, an opening was made through which we crawled.

"You're hurt, sir!" One of the men took Gordon's arm.

My companion shook him off.

"There's no time to lose! Out of here, as quick as we can go!"

I saw that we were in a basement of some sort. We hastened up the steps and out into the early dawn which was turning the east scarlet. Over the tops of smaller houses I saw in the distance a great gaunt building on the roof of which, I felt instinctively, that wild drama had been enacted the night before.

"That building was leased some months ago by a mysterious Chinaman," said Gordon, following my gaze. "Office building originally--the neighborhood deteriorated and the building stood vacant for some time. The new tenant added several stories to it but left it apparently empty. Had my eye on it for some time."

This was told in Gordon's jerky swift manner as we started hurriedly along the sidewalk. I listened mechanically, like a man in a trance. My vitality was ebbing fast and I knew that I was going to crumple at any moment.

"The people living in the vicinity had been reporting strange sights and noises. The man who owned the basement we just left heard queer sounds emanating from the wall of the basement and called the police. About that time I was racing back and forth among those cursed corridors like a hunted rat and I heard the police banging on the wall. I found the secret door and opened it but found it barred by a grating. It was while I was telling the astounded policemen to procure a hacksaw that the pursuing negroes, whom I had eluded for the moment, came into sight and I was forced to shut the door and run for it again. By pure luck I found you and by pure luck managed to find the way back to the door.

"Now we must get to Scotland Yard. If we strike swiftly, we may capture the entire band of devils. Whether I killed Kathulos or not I do not know, or if he can be killed by mortal weapons. But to the best of my knowledge all of them are now in those subterranean corridors and----"

At that moment the world shook! A brain-shattering roar seemed to break the sky with its incredible detonation; houses tottered and crashed to ruins; a mighty pillar of smoke and flame burst from the earth and on its wings great masses of debris soared skyward. A black fog of smoke and dust and falling timbers enveloped the world, a prolonged thunder seemed to rumble up from the center of the earth as of walls and ceilings falling, and amid the uproar and the screaming I sank down and knew no more.

_21. The Breaking of the Chain_

"And like a soul belated, In heaven and hell unmated, By cloud and mist abated, Comes out of darkness morn."

--Swinburne.

There is little need to linger on the scenes of horror of that terrible London morning. The world is familiar with and knows most of the details attendant to the great explosion which wiped out a tenth of that great city with a resultant loss of lives and property. For such a happening some reason must needs be given; the tale of the deserted building got out, and many wild stories were circulated. Finally, to still the rumors, the report was unofficially given out that this building had been the rendezvous and secret stronghold of a gang of international anarchists, who had stored its basement full of high explosives and who had supposedly ignited these accidentally. In a way there was a good deal to this tale, as you know, but the threat that had lurked there far transcended any anarchist.

All this was told to me, for when I sank unconscious, Gordon, attributing my condition to exhaustion and a need of the hashish to the use of which he thought I was addicted, lifted me and with the aid of the stunned policemen got me to his rooms before returning to the scene of the explosion. At his rooms he found Hansen, and Zuleika handcuffed to the bed as I had left her. He released her and left her to tend to me, for all London was in a terrible turmoil and he was needed elsewhere.

When I came to myself at last, I looked up into her starry eyes and lay quiet, smiling up at her. She sank down upon my bosom, nestling my head in her arms and covering my face with her kisses.

"Steephen!" she sobbed over and over, as her tears splashed hot on my face.

I was scarcely strong enough to put my arms about her but I managed it, and we lay there for a space, in silence except for the girl's hard, racking sobs.

"Zuleika, I love you," I murmured.

"And I love you, Steephen," she sobbed. "Oh, it is so hard to part now--but I'm going with you, Steephen; I can't live without you!"

"My dear child," said John Gordon, entering the room suddenly, "Costigan's not going to die. We will let him have enough hashish to tide him along, and when he is stronger we will take him off the habit slowly."

"You don't understand, sahib; it is not hashish Steephen must have. It is something which only the Master knew, and now that he is dead or is fled, Steephen can not get it and must die."

Gordon shot a quick, uncertain glance at me. His fine face was drawn and haggard, his clothes sooty and torn from his work among the debris of the explosion.

"She's right, Gordon," I said languidly, "I'm dying. Kathulos killed the hashish-craving with a concoction he called the elixir. I've been keeping myself alive on some of the stuff that Zuleika stole from him and gave me, but I drank it all last night."

I was aware of no craving of any kind, no physical or mental discomfort even. All my mechanism was slowing down fast; I had passed the stage where the need of the elixir would tear and rend me. I felt only a great lassitude and a desire to sleep. And I knew that the moment I closed my eyes, I would die.

"A strange dope, that elixir," I said with growing languor. "It burns and freezes and then at last the craving kills easily and without torment."

"Costigan, curse it," said Gordon desperately, "you can't go like this! That vial I took from the Egyptian's table--what is in it?"

"The Master swore it would free me of my curse and probably kill me also," I muttered. "I'd forgotten about it. Let me have it; it can no more than kill me and I'm dying now."

"Yes, quick, let me have it!" exclaimed Zuleika fiercely, springing to Gordon's side, her hands passionately outstretched. She returned with the vial which he had taken from his pocket, and knelt beside me, holding it to my lips, while she murmured to me gently and soothingly in her own language.

I drank, draining the vial, but feeling little interest in the whole matter. My outlook was purely impersonal, at such a low ebb was my life, and I can not even remember how the stuff tasted. I only remember feeling a curious sluggish fire burn faintly along my veins, and the last thing I saw was Zuleika crouching over me, her great eyes fixed with a burning intensity on me. Her tense little hand rested inside her blouse, and remembering her vow to take her own life if I died I tried to lift a hand and disarm her, tried to tell Gordon to take away the dagger she had hidden in her garments. But speech and action failed me and I drifted away into a curious sea of unconsciousness.

Of that period I remember nothing. No sensation fired my sleeping brain to such an extent as to bridge the gulf over which I drifted. They say I lay like a dead man for hours, scarcely breathing, while Zuleika hovered over me, never leaving my side an instant, and fighting like a tigress when anyone tried to coax her away to rest. Her chain was broken.

* * * * *

As I had carried the vision of her into that dim land of nothingness, so her dear eyes were the first thing which greeted my returning consciousness. I was aware of a greater weakness than I thought possible for a man to feel, as if I had been an invalid for months, but the life in me, faint though it was, was sound and normal, caused by no artificial stimulation. I smiled up at my girl and murmured weakly:

"Throw away your dagger, little Zuleika; I'm going to live."

She screamed and fell on her knees beside me, weeping and laughing at the same time. Women are strange beings, of mixed and powerful emotions, truly.

Gordon entered and grasped the hand which I could not lift from the bed.

"You're a case for an ordinary human physician now, Costigan," he said. "Even a layman like myself can tell that. For the first time since I've known you, the look in your eyes is entirely sane. You look like a man who has had a complete nervous breakdown, and needs about a year of rest and quiet. Great heavens, man, you've been through enough, outside your dope experience, to last you a lifetime."

"Tell me first," said I: "Was Kathulos killed in the explosion?"

"I don't know," answered Gordon somberly. "Apparently the entire system of subterranean passages was destroyed. I know my last bullet--the last bullet that was in the revolver which I wrested from one of my attackers--found its mark in the Master's body, but whether he died from the wound, or whether a bullet can hurt him, I do not know. And whether in his death agonies he ignited the tons and tons of high explosives which were stored in the corridors, or whether the negroes did it unintentionally, we shall never know.

"My God, Costigan, did you ever see such a honeycomb? And we know not how many miles in either direction the passages reached. Even now Scotland Yard men are combing the subways and basements of the town for secret openings. All known openings, such as the one through which we came and the one in Soho 48, were blocked by falling walls. The office building was simply blown to atoms."

"What about the men who raided Soho 48?"

"The door in the library wall had been closed. They found the Chinaman you killed, but searched the house without avail. Lucky for them, too, else they had doubtless been in the tunnels when the explosion came, and perished with the hundreds of negroes who must have died then."

"Every negro in London must have been there."

"I dare say. Most of them are voodoo worshipers at heart and the power the Master wielded was incredible. They died, but what of him? Was he blown to atoms by the stuff which he had secretly stored, or crushed when the stone walls crumbled and the ceilings came thundering down?"

"There is no way to search among those subterranean ruins, I suppose?"

"None whatever. When the walls caved in, the tons of earth upheld by the ceilings also came crashing down, filling the corridors with dirt and broken stone, blocking them forever. And on the surface of the earth, the houses which the vibration shook down were heaped high in utter ruins. What happened in those terrible corridors must remain forever a mystery."

* * * * *

My tale draws to a close. The months that followed passed uneventfully, except for the growing happiness which to me was paradise, but which would bore you were I to relate it. But one day Gordon and I again discussed the mysterious happenings that had had their being under the grim hand of the Master.

"Since that day," said Gordon, "the world has been quiet. Africa has subsided and the East seems to have returned to her ancient sleep. There can be but one answer--living or dead, Kathulos was destroyed that morning when his world crashed about him."

"Gordon," said I, "what is the answer to that greatest of all mysteries?"

My friend shrugged his shoulders.

"I have come to believe that mankind eternally hovers on the brinks of secret oceans of which it knows nothing. Races have lived and vanished before our race rose out of the slime of the primitive, and it is likely still others will live upon the earth after ours has vanished. Scientists have long upheld the theory that the Atlanteans possessed a higher civilization than our own, and on very different lines. Certainly Kathulos himself was proof that our boasted culture and knowledge were nothing beside that of whatever fearful civilization produced him.

"His dealings with you alone have puzzled all the scientific world, for none of them has been able to explain how he could remove the hashish craving, stimulate you with a drug so infinitely more powerful, and then produce another drug which entirely effaced the effects of the other."

"I have him to thank for two things," I said slowly; "the regaining of my lost manhood--and Zuleika. Kathulos, then, is dead, as far as any mortal thing can die. But what of those others--those 'ancient masters' who still sleep in the sea?"

Gordon shuddered.

"As I said, perhaps mankind loiters on the brink of unthinkable chasms of horror. But a fleet of gunboats is even now patrolling the oceans unobtrusively, with orders to destroy instantly any strange case that may be found floating--to destroy it and its contents. And if my word has any weight with the English government and the nations of the world, the seas will be so patrolled until doomsday shall let down the curtain on the races of today."

"At night I dream of them, sometimes," I muttered, "sleeping in their lacquered cases, which drip with strange seaweed, far down among the green surges--where unholy spires and strange towers rise in the dark ocean."

"We have been face to face with an ancient horror," said Gordon somberly, "with a fear too dark and mysterious for the human brain to cope with. Fortune has been with us; she may not again favor the sons of men. It is best that we be ever on our guard. The universe was not made for humanity alone; life takes strange phases and it is the first instinct of nature for the different species to destroy each other. No doubt we seemed as horrible to the Master as he did to us. We have scarcely tapped the chest of secrets which nature has stored, and I shudder to think of what that chest may hold for the human race."

"That's true," said I, inwardly rejoicing at the vigor which was beginning to course through my wasted veins, "but men will meet obstacles as they come, as men have always risen to meet them. Now, I am beginning to know the full worth of life and love, and not all the devils from all the abysses can hold me."

Gordon smiled.

"You have it coming to you, old comrade. The best thing is to forget all that dark interlude, for in that course lies light and happiness."
