Now, watch."
As the weight fell upon the step it gave way so slightly as to be almost imperceptible, but suddenly from hidden cavities around the well-like shaft there came six rings of long, sharp steel spikes, set inwards, three above and three below, which, contracting as they came forward, met and interlaced. In an instant I recognised what terrible fate would be the lot of any adventurer who dared to enter that dark shaft. The action of stepping upon that fatal projecting iron released hydraulic pressure of irresistible power, and the unfortunate one, unable to ascend or descend by reason of the danger being above and below, must be impaled by a hundred cruel spikes, sharp and double-edged like spears, while the bands whereon they were set must crush his bones to pulp.
I looked at this terrible device for producing an agonizing death and shuddered. The precautions taken to prevent anyone entering the place were the most elaborate and ingenious I had ever seen. Even if any person learnt the secret of draining the lake, the shaft leading to the mysterious subterranean place was unapproachable by reason of this extraordinary mechanical device.
During five minutes the spikes remained interlaced, then automatically they disengaged themselves, and slowly fell back into the cavity running round the brickwork, wherein they remained concealed.
Thrice again did Omar repeat this action of pressing the bar upon the step, each time with an exactly similar result, chatting to me the while.
Then, when for the third time the spikes had fallen back into their places, he said:
"Now the secret to avoid this and lock the mechanism is to turn back this little lever and place it in this catch, so. This cannot, however, be done unless the step has been pressed three times."
And bending over he showed me another tiny lever thickly encrusted with rust, secreted behind a movable brick in the first tier below the lake"s bottom. This he placed in position, securing it in a niche so that it became immovable.
"Now," he said, "we may descend without fear," and with these words knelt down, and after lighting a torch he had brought with him, commenced the descent into the cavernous gloom. I quickly followed, my feet resting for a brief instant upon the fatal iron projection, but no spikes came forward, for the terrible mechanism was now locked. Deep down into this circular shaft we went, the smoke and sparks from Omar"s torch ever ascending into my face as I lowered myself from rung to rung, until at last, at considerable depth, we found ourselves in a kind of natural cavern. The place seemed damp and full of bad odours, to which submitting with patience we, by a long pa.s.sage, sometimes crawling under rugged arches, sometimes wading in mud and dirt, attained the end of the cavern, where we stumbled on some narrow steps; but the torch shed little light, and we became nearly suffocated by the noisome vapours.
"I thought you said the air was fresh here," I exclaimed good-humouredly to my companion.
"So I did," he answered. "I cannot make out why it has become so foul.
The air-holes must have become accidentally stopped up."
The widening ascent was so intricate and clogged with dirt and rubbish that we worked like moles in the dark; nevertheless, by diligent industry we gained ground considerably, yet as we endeavoured to mount, the slimy steps slipped from under us, and ever and anon we would come tumbling down with a weight of dirt upon us.
After various labours, however, we suddenly entered a great cavern, quite dry. From its roof hung great stalact.i.tes that glittered and sparkled in the torch"s uncertain light, while around the rough walls of this natural chamber were heaped in profusion great heavy chests of iron and adamant.
With the torch held high above his head Omar rushed across to the pile and bending, examined one chest after the other. Then, raising himself as the truth suddenly dawned upon him, he cried in a hoa.r.s.e, excited voice:
"By the power of Zomara, we have been tricked!"
"Tricked! How?" I gasped in alarm.
"Cannot you see?" he wailed. "This, the Treasure-house of the Sanoms, has been entered and its contents, worth a fabulous sum, have been extracted!
See! Each trunk has been forced by explosives!"
I gazed eagerly where he directed, and saw that the trunks of iron and stone had been blown open by gunpowder, for on each remained a blackened patch, showing plainly the means used to force the strong chest wherein reposed the magnificent jewels, the vessels of gold, and the historic gem-encrusted and invulnerable armour of the Nabas of Mo.
"Then this is the place the secret of which the villainous old Arab, Samory, endeavoured to wrench from you by torture," I exclaimed, gazing round the grim, weird cavern.
"Yes," he answered. "This is the Treasure house of my ancestors. Since the days of King Karmos each Naba or Naya has added to the great store of treasure ama.s.sed for the purpose of the emanc.i.p.ation of our country in the day of need. Only the reigning monarch and the heir have, in any generation, ever known the secret of how the Treasure-house can be approached--the secret I have to-day revealed to you as Keeper of the Treasure."
"But if you alone knew the secret, who could have ransacked the place?" I asked. "The chests seem to have been recently opened."
"True," he answered, and pointing to a heap of bejewelled swords, breastplates and helmets, that had apparently been hastily cast aside as the least valuable of the great treasure, he added: "All the most historic and beautiful jewels have been taken, and the gold vessels and things of minor value left. See! It is plain that the theft was accomplished in all haste, for there was scarce time to sort the gems that are unique from those rivalled by others."
"It certainly looks as if the jewels were secured in feverish haste," I said, at the same time picking up from the uneven floor a bronze oil lamp lying overturned and discarded.
Together we set about making a systematic examination of the various chests, numbering nearly one hundred. Those fashioned from single stones were of great age, looking like coffins, while those of iron were ponderous caskets bound with huge bands, studded and double-locked, with great antique hinges of marvellous workmanship. With perhaps half a dozen exceptions the lid of each had yielded to the charge of explosive placed beneath it, while in many cases the whole side of the casket had been blown completely out, injuring or destroying some of its valuable contents. Jewellery and gems, set and unset, had been strewn about and trodden into the dust by hurrying feet, and a few that I recognized at once as of fabulous value had been overlooked. Stooping, I picked up from the dirt a marvellously-cut ruby, almost the size of a pigeon"s egg. But the majority of the treasure-chests had been emptied. The place had been visited, and the vast wealth of a nation stolen.
"For the first time in the long, glorious history of my land has the Treasure-house been entered by thieves," Omar said, as if to himself. "No mere adventurer can have been here; this great robbery is the result of some base conspiracy. The treasure of the Sanoms, renowned through the whole world as the most wondrous collection of magnificent and unsurpa.s.sable gems, has been cleared out and the entrance re-closed in a manner little short of marvellous. To-day is indeed a sad one for Mo, and for me. My inheritance has been taken from me."
"By whom?" I inquired, continuing my way, examining one of the few chests that had apparently not been tampered with. But, as in the gloom I hastened from one casket to another, my foot suddenly struck against some object, causing me to lose my balance, and thus tripped, were it not for the fact that I clutched at the corner of the great chest, I should have fallen upon my face.
Bending to examine what it was, I was amazed to discover the body of a male slave, still dressed in the uniform of the servants of the palace, but rapidly decomposing. It was the faint sickening odour emitted from the corpse that had greeted our nostrils when we entered the place.
We both bent and looked at him, astounded at discovering, still imbedded in his back, a long keen knife. He had been struck down from behind and murdered, while in the act of securing some of the treasure, for his brown withered fingers still grasped a beautiful necklet of magnificent pearls, an ornament worth several thousand English pounds.
"That is one of the Naya"s personal attendants," observed Omar, recognizing the dress, but unable to distinguish the features of the murdered man, so decomposed were they. "He perhaps partic.i.p.ated in the plot, and to secure his silence, or his portion of the booty, his fellow-conspirators struck him to earth."
"But to whom is due the chief responsibility in this affair?" I asked.
"Surely you have some suspicion?"
"I know not," he answered. "Besides myself only the Naya knew the secret means by which the treasure might be reached."
"Then in all probability she secured it before her flight!" I cried.
"That may be the truth," he answered in a tone of suppressed agitation.
"Immediately she obtained knowledge through her spies of my intention to disobey her, she may have secured the most valuable of the jewels and had them packed ready to take them with her if compelled to flee. Yet somehow I cannot believe she has done this, for their removal must have attracted attention. No, I believe we shall have to look in another quarter for the thief." Then, bending again to examine the hilt of the knife embedded in the body of the unfortunate slave, he added: "That poignard was hers. She carried it always in her girdle, and it seems, after all, as though this man was her confidant and a.s.sistant, and that here alone she closed his lips by murdering him. Yet to her, life was more valuable than the treasure, and I cannot believe that she risked detection and capture in order to secure what she might afterwards obtain by the a.s.sistance of hirelings."
"A dark tragedy has certainly been enacted," I said, glancing around the gruesome place with its gloomy corners and crevices where the blackness was impenetrable. "The theft has been accompanied by a secret a.s.sa.s.sination at some coward"s hand."
"Yes," he exclaimed, standing with folded arms and chin sunk upon his breast. "The great treasure, belonging not only to our family but to our nation, has been stolen, and I swear by Zomara"s power that I will seek out the thief and recover it. I am Naba, and it is my duty to my people to restore their wealth to its hiding-place. Each successive ruler has enriched his country by making additions to the store of jewels, and it shall never be recorded that on finding the most valuable of our possessions stolen, I made no effort to trace and recover them. True, they have been abstracted in a manner almost miraculous for ingenuity and rapidity, but from this moment I will not rest until they are recovered.
And you, Scarsmere, as Keeper of the Treasure-house, shall a.s.sist me."
"I am ready," I answered, excited at the prospect of this new task before us. "We will spare no effort to seek the thief and recover the Treasure of the Sanoms. It is, as you declare, a duty, and I am ready and anxious to commence the search."
CHAPTER x.x.xI.
A SPY"S STARTLING STORY.
WE remained fully two hours in the noisome Treasure-chamber of the Sanoms, the early history of which was lost in the mist of legendary lore, then after careful and minute examination of the rifled chests, worked our way to the base of the shaft, and, having ascended, let down the tiny concealed lever, thereby allowing the pressure to increase, and place in position the ingenious contrivance for causing death to the venturesome. Replacing the iron plate that closed the mouth of the well-like aperture, we screwed it down, rendering it water-tight, and, crossing the stones, regained the bank of the lake. Then, having turned back the lever, the flood-gates slowly closed down again, and, ere we mounted our horses to ride back to the city, the waters, fed by the many torrents, had already risen sufficiently to hide the slime-covered entrance to the secret chamber.
One of the greatest thefts in the world"s history had been committed, and the question that puzzled us was the ident.i.ty of the thief. Our first suspicions had fallen upon the Naya, but calmly discussing the question as we rode back, we both became convinced that so critical was the deposed ruler"s position, that she would never have undertaken all the risks in removing the treasure. She knew she was in deadly peril of her life, and that every moment lost was of vital importance, therefore it was hardly probable that she would have delayed her departure to secure the wealth of her ancestors.
Omar argued that if compelled to fly she might have afterwards entrusted the secret of the Treasure-house to spies, who could have returned and secured the jewels. That she had not done this was certain, for the time that had elapsed since her flight was insufficient.
I suggested that the detachment of Samory"s men who had entered the city during the revolt might have had knowledge of the secret and secured the treasure, but Omar pointed out that none in Samory"s camp could have been aware of the means by which the place could be entered, Kouaga himself being in ignorance.
"Then the thief was the Naya herself," I said, decisively.
"No; after all, I am not actually positive that such is the case," he answered. "There are facts connected with the affair, trivial in themselves, that lead me to believe otherwise."
"What are they?"
"One is that the wonderful ruby necklet, an ornament of matchless gems that belonged to King Karmos and is one of the talismans of the Sanoms, has been left. I found it flung aside and discarded. Had the Naya committed the theft she would have secured this first of all, because of our family tradition that no reigning Sanom can live longer than three moons without it is in his or her possession."
