We retraced our steps to the foot of the stair. In the wall on their left was an opening, low down against the floor and little more than three feet high; it reminded me of some of the entrances to those seemingly interminable pa.s.sages whereby one approaches the sepulchral chambers of the Egyptian Pyramids.

"Now for it!" snapped Smith. "Follow me closely."

Down he dropped, and, having the lamp thrust out before him, began to crawl into the tunnel. As his heels disappeared, and only a faint light outlined the opening, I dropped upon all fours in turn, and began laboriously to drag myself along behind him. The atmosphere was damp, chilly, and evil-smelling; therefore, at the end of some ten or twelve yards of this serpentine crawling, when I saw Smith, ahead of me, to be standing erect, I uttered a stifled exclamation of relief. The thought of Karamaneh having been dragged through this noisome hole was one I dared not dwell upon.

A long, narrow pa.s.sage now opened up, its end invisible from where we stood. Smith hurried forward. For the first thirty of forty paces the roof was formed of ma.s.sive stone slabs; then its character changed; the pa.s.sage became lower, and one was compelled frequently to lower the head in order to avoid the oaken beams which crossed it.

"We are pa.s.sing under the dining-room," said Smith. "It was from here the sound of beating first came!"

"What do you mean?"

"I have built up a theory, which remains to be proved, Petrie. In my opinion a captive of the Yellow group escaped to-night and sought to summon a.s.sistance, but was discovered and overpowered."

"Sir Lionel?"

"Sir Lionel, or Kennedy--yes, I believe so."

Enlightenment came to me, and I understood the pitiable condition into which the Greek butler had been thrown by the phenomenon of the ghostly knocking. But Smith hurried on, and suddenly I saw that the pa.s.sage had entered upon a sharp declivity; and now both roof and walls were composed of crumbling brickwork. Smith pulled up, and thrust back a hand to detain me.

"_Ssh!_" he hissed, and grasped my arm.

Silent, intently still, we stood and listened. The sound of a guttural voice was clearly distinguishable from somewhere close at hand!

Smith extinguished the lamp. A faint luminance proclaimed itself directly ahead. Still grasping my arm, Smith began slowly to advance toward the light. One--two--three--four--five paces we crept onward ...

and I found myself looking through an archway into a medieval torture-chamber!

Only a part of the place was visible to me, but its character was unmistakable. Leg-irons, boots and thumb-screws hung in racks upon the fungi-covered wall. A ma.s.sive, iron-studded door was open at the further end of the chamber, and on the threshold stood h.o.m.opoulo, holding a lantern in his hand.

Even as I saw him, he stepped through, followed by on of those short, thick-set Burmans of whom Dr. Fu-Manchu had a number among his entourage; they were members of the villainous robber bands notorious in India as the dacoits. Over one broad shoulder, slung sackwise, the dacoit carried a girl clad in scanty white drapery....

Madness seized me, the madness of sorrow and impotent wrath. For, with Karamaneh being borne off before my eyes, I dared not fire at her abductors lest I should strike _her_!

Nayland Smith uttered a loud cry, and together we hurled ourselves into the chamber. Heedless of what, of whom, else it might shelter, we sprang for the group in the distant doorway. A memory is mine of the dark, white face of h.o.m.opoulo, peering, wild-eyed, over the lantern, of the slim, white-clad form of the lovely captive seeming to fade into the obscurity of th pa.s.sage beyond.

Then, with bleeding knuckles, with wild imprecations bubbling from my lips, I was battering upon the mighty door--which had been slammed in my face at the very instant that I had gained it.

"Brace up, man!--Brace up!" cried Smith, and in his strenuous, grimly purposeful fashion, he shouldered me away from the door. "A battering ram could not force that timber; we must seek another way!"

I staggered, weakly, back into the room. Hand raised to my head, I looked about me. A lantern stood in a niche in one wall, weirdly illuminating that place of ghastly memories; there were braziers, branding-irons, with other instruments dear to the Black Ages, about me--and gagged, chained side by side against the opposite wall, lay Sir Lionel Barton and another man unknown to me!

Already Nayland Smith was bending over the intrepid explorer, whose fierce blue eyes glared out from the sun-tanned face madly, whose gray hair and mustache literally bristled with rage long repressed.

I choked down the emotions that boiled and seethed within me, and sought to release the second captive, a stockily-built, clean-shaven man. First I removed the length of toweling which was tied firmly over his mouth; and--

"Thank you, sir," he said composedly. "The keys of these irons are on the ledge there beside the lantern. I broke the first ring I was chained to, but the Yellow devils overhauled me, all manacled as I was, half-way along the pa.s.sage before I could attract your attention, and fixed me up to another and stronger ring!"

Ere he had finished speaking, the keys were in my hands, and I had unlocked the gyves from both the captives. Sir Lionel Barton, his gag removed, unloosed a torrent of pent-up wrath.

"The h.e.l.l-fiends drugged me!" he shouted. "That black villain h.o.m.opoulo doctored my tea! I woke in this d.a.m.nable cell, the secret of which has been lost for generations!" He turned blazing blue eyes upon Kennedy.

"How did _you_ come to be trapped?" he demanded unreasonably. "I credited you with a modic.u.m of brains!"

"h.o.m.opoulo came running from your room, sir, and told me you were taken suddenly ill and that a doctor must be summoned without delay."

"Well, well, you fool!"

"Dr. Hamilton was away, sir."

"A false call beyond doubt!" snapped Smith.

"Therefore I went for the new doctor, Dr. Magnus, in the village. He came at once and I showed him up to your room. He sent Mrs. Oram out, leaving only h.o.m.opoulo and myself there, except yourself."

"Well?"

"Sandbagged!" explained the man nonchalantly. "Dr. Magnus, who is some kind of dago, is evidently one of the gang."

"Sir Lionel!" cried Smith--"where does the pa.s.sage lead to beyond that doorway?

"G.o.d knows!" was the answer, which dashed my last hope to the ground.

"I have no more idea than yourself. Perhaps ..."

He ceased speaking. A sound had interrupted him, which, in those grim surroundings, lighted by the solitary lantern, translated my thoughts magically to Ancient Rome, to the Rome of Tigellinus, to the dungeons of Nero's Circus. Echoing eerily along the secret pa.s.sages it came-- the roaring and snarling of the lioness and the leopards.

Nayland Smith clapped his hand to his brow and stared at me almost frenziedly, then--

"G.o.d guard her!" he whispered. "Either their plans, wherever they got them, are inaccurate, or in their panic they have mistaken the way." ...

Wild cries now were mingling with the snarling of the beasts....

"They have blundered into the old crypt!"

How we got out of the secret labyrinth of Graywater Park into the grounds and around the angle of the west wing to the ivy-grown, pointed door, where once the chapel had bee, I do not know. Light seemed to spring up about me, and half-clad servants to appear out of the void. Temporarily I was insane.

Sir Lionel Barton was behaving like a madman too, and like a madman he tore at the ancient bolts and precipitated himself into the stone-paved cloister barred with the moon-cast shadows of the Norman pillars. From behind the iron bars of the home of the leopards came now a fearsome growling and scuffling.

Smith held the light with a steady hand, whilst Kennedy forced the heavy bolts of the crypt door.

In leapt the fearless baronet among his savage pets, and in the ray of light from the electric lamp I saw that which turned my sick with horror. p.r.o.ne beside a yawning gap in the floor lay h.o.m.opoulo, his throat torn indescribably and his white shirt-front smothered in blood. A black leopard, having its fore-paws upon the dead man's breast, turned blazing eyes upon us; a second crouched beside him.

Heaped up in a corner of the place, amongst the straw and litter of the lair, lay the Burmese dacoit, his sinewy fingers embedded in the throat of the third and largest leopard--which was dead--whilst the creature's gleaming fangs were buried in the tattered flesh of the man's shoulder.

Upon the straw beside the two, her slim, bare arms outstretched and her head pillowed upon them, so that her rippling hair completely concealed her face, lay Karamaneh....

In a trice Barton leapt upon the great beast standing over h.o.m.opoulo, had him by the back of the neck and held him in his powerful hands whining with fear and helpless as a rat in the grip of a terrier. The second leopard fled into the inner lair.

So much I visualized in a flash; then all faded, and I knelt alone beside her whose life was my life, in a world grown suddenly empty and still.

Through long hours of agony I lived, hours contained within the span of seconds, the beloved head resting against my shoulder, whilst I searched for signs of life and dreaded to find ghastly wounds.... At first I could not credit the miracle; I could not receive the wondrous truth.

Karamaneh was quite uninjured and deep in drugged slumber!

"The leopards thought her dead," whispered Smith brokenly, "and never touched her!"
