Why had the man dwelt in this desolate spot, and to what unknown destination had his servants departed after disposing of their master's corpse?

Conan shrugged his shoulders and thrust the parchment back into his girdle — he started violently, the skin on the backs of his hands tingling. Startingly, shockingly in the slumberous stillness, there had boomed the deep strident clangor of a great gong!

He wheeled, crouching like a great cat, sword in hand, glaring down the narrow corridor from which the sound had seemed to come. Had the priests of Keshia arrived? This was improbable, he knew; they would not have had time to reach the valley. But that gong was indisputable evidence of human presence.

Conan was basically a direct-actionist. Such subtlety as he possessed had been acquired through contact with the more devious races. When taken off guard by some unexpected occurrence, he reverted instinctively to type. So now, instead of hiding or slipping away in the opposite direction as the average man might have done, he ran straight down the corridor in the direction of the sound. His sandals made no more sound than the pads of a panther would have made; his eyes were slits, his lips unconsciously asnarl. Panic had momentarily touched his soul at the shock of that unexpected reverberation, and the red rage of the primitive that is wakened by threat of peril, always lurked close to the surface of the Cimmerian.

He emerged presently from the winding corridor into a small open court. Something glinting in the sun caught his eye. It was the gong, a great gold disk, hanging from a gold arm extending from the crumbling wall. A brass mallet lay near, but there was no sound or sight of humanity. The surrounding arches gaped emptily. Conan crouched inside the doorway for what seemed a long time. There was no sound or movement throughout the great palace. His patience exhausted at last, he glided around the curve of the court, peering into the arches, ready to leap either way like a flash of light, or to strike right or left as a cobra strikes.

He reached the gong, started into the arch nearest it. He saw only a dim chamber, littered with the debris of decay. Beneath the gong the polished marble flags showed no footprint, but there was a scent in the air — a faintly fetid odor he could not classify; his nostrils dilated like those of a wild beast as he sought in vain to identify it.

He turned toward the arch — with appalling suddenness the seemingly solid flags splintered and gave way under his feet. Even as he fell he spread wide his arms and caught the edges of the aperture that gaped beneath him. The edges crumbled off under his clutching fingers. Down into utter blackness he shot, into black icy water that gripped him and whirled him away with breathless speed.

The Cimmerian at first made no attempt to fight the current that was sweeping him through lightless night. He kept himself afloat, gripping between his teeth the sword, which he had not relinquished, even in his fall, and did not seek to guess to what doom he was being borne. But suddenly a beam of light lanced the darkness ahead of him. He saw the surging, seething black surface of the water, in turmoil as if disturbed by some monster of the deep, and he saw the sheer stone walls of the channel curved up to a vault overhead. On each side ran a narrow ledge, just below the arching roof, but they were far out of his reach. At one point this roof had been broken, probably fallen in, and the light was streaming through the aperture. Beyond that shaft of light was utter blackness, and panic assailed the Cimmerian as he saw he would be swept on past that spot of light, and into the unknown blackness again.

Then he saw something else: bronze ladders extending from the ledges to the water's surface at regular intervals, and there was one just ahead of him. Instantly he struck out for it, fighting the current that would have held him to the middle of the stream. It dragged at him as with tangible, animate, slimy hands, but he buffeted the rushing surge with the strength of desperation and drew closer and closer inshore, fighting furiously for every inch. Now he was even with the laddeer and with a fierce, gasping plunge he gripped the bottom rung and hung on, breathless.

A few seconds later he struggled up out of the seething water, trusting his weight dubiously to the corroded rungs. They sagged and bent, but they held, and he clambered up onto the narrow ledge which ran along the wall scarcely a man's length below the curving roof. The tall Cimmerian was forced to bend his head as he stood up. A heavy bronze door showed in the stone at a point even with the head of the ladder, but it did not give to Conan's efforts. He transferred his sword from his teeth to its scabbard, spitting blood — for the edge had cut his lips in that fierce fight with the river — and turned his attention to the broken roof.

He could reach his arms up through the crevice and grip the edge, and careful testing told him it would bear his weight. An instant later he had drawn himself up through the hole, and found himself in a wide chamber, in a state of extreme disrepair. Most of the roof had fallen in, as well as a great section of the floor, which was laid over the vault of a subterranean river. Broken arches opened into other chambers and corridors, and Conan believed he was still in the great palace. He wondered uneasily how many chambers in that palace had underground water directly under them, and when the ancient flags or tiles might give way again and precipitate him back into the current from which he had just crawled.

And he wondered just how much of an accident that fall had been. Had those rotten flags simply chanced to give way beneath his weight, or was there a more sinister explanation? One thing at least was obvious: he was not the only living thing in that palace. That gong had not sounded of its own accord, whether the noise had been meant to lure him to his death, or not. The silence of the palace became suddenly sinister, fraught with crawling menace.

Could it be someone on the same mission as himself? A sudden thought occurred to him, at the memory of the mysterious Bit-Yakin. Was it not possible that this man had found the Teeth of Gwahlur in his long residence in Alkmeenon — that his servants had taken them with them when they departed? The possibility that he might be following a will-o'-the-wisp infuriated the Cimmerian.

Choosing a corridor which he believed led back toward the part of the palace he had first entered, he hurried along it, stepping gingerly as he thought of that black river that seethed and foamed somewhere below his feet.

His speculations recurrently revolved about the oracle chamber and its cryptic occupant. Somewhere in that vicinity must be the clue to the mystery of the treasure, if indeed it still remained in its immemorial hiding place.

The great palace lay silent as ever, disturbed only by the swift passing of his sandaled feet. The chambers and halls he traversed were crumbling into ruin, but as he advanced the ravages of decay became less apparent. He wondered briefly for what purpose the ladders had been suspended from the ledges over the subterranean river, but dismissed the matter with a shrug. He was little interested in speculating over unremunerative problems of antiquity.

He was not sure just where the oracle chamber lay, from where he was, but presently he emerged into a corridor which led back into the great throne room under one of the arches. He had reached a decision; it was useless for him to wander aimlessly about the palace, seeking the hoard. He would conceal himself somewhere here, wait until the Keshani priests came, and then, after they had gone through the farce of consulting the oracle, he would follow them to the hiding place of the gems, to which he was certain they would go. Perhaps they would take only a few of the jewels with them. He would content himself with the rest.
