In what had seemed a curtain of solid marble, a thin perpendicular crack showed and in the crack hung a wisp of silk. In an instant he was bending over it. That shred was from Muriela’s torn skirt. The implication was unmistakable. It had been caught in the closing door and torn off as she was borne through the opening by whatever grim beings were her captors. The bit of clothing had prevented the door from fitting perfectly into its frame.
Thrusting his dagger-point into the crack, Conan exerted leverage with a corded forearm. The blade bent, but it was of unbreakable Akbitanan steel. The marble door opened. Conan’s sword was lifted as he peered into the aperture beyond, but he saw no shape of menace. Light filtering into the oracle chamber revealed a short flight of steps cut out of marble. Pulling the door back to its fullest extent, he drove his dagger into a crack in the floor, propping it open. Then he went down the steps without hesitation. He saw nothing, heard nothing. A dozen steps down, the stair ended in a narrow corridor which ran straight away into gloom.
He halted suddenly, posed like a statue at the foot of the stair, staring at the paintings which frescoed the walls, half visible in the dim light which filtered down from above. The art was unmistakably Pelishti; he had seen frescoes of identical characteristics on the walls of Asgalun. But the scenes depicted had no connection with anything Pelishti, except for one human figure, frequently recurrent: a lean, white-bearded old man whose racial characteristics were unmistakable. They seemed to represent various sections of the palace above. Several scenes showed a chamber he recognized as the oracle chamber with the figure of Yelaya stretched upon the ivory dais and huge black men kneeling before it. And there behind the wall, in the niche, lurked the ancient Pelishti. And there were other figures, too — figures that moved through the deserted palace, did the bidding of the Pelishti, and dragged unnamable things out of the subterranean river. In the few seconds Conan stood frozen, hitherto unintelligible phrases in the parchment manuscript blazed in his brain with chilling clarity. The loose bits of the pattern clicked into place. The mystery of Bit-Yakin was a mystery no longer, nor the riddle of Bit-Yakin’s servants.
Conan turned and peered into the darkness, an icy finger crawling along his spine. Then he went along the corridor, cat-footed, and without hesitation, moving deeper and deeper into the darkness as he drew farther away from the stair. The air hung heavy with the odor he had scented in the court of the gong.
Now in utter blackness he heard a sound ahead of him — the shuffle of bare feet, or the swish of loose garments against stone, he could not tell which. But an instant later his outstretched hand encountered a barrier which he identified as a massive door of carved metal. He pushed against it fruitlessly, and his sword-point sought vainly for a crack. It fitted into the sill and jambs as if molded there. He exerted all his strength, his feet straining against the floor, the veins knotting in his temples. It was useless; a charge of elephants would scarcely have shaken that titanic portal.
As he leaned there he caught a sound on the other side that his ears instantly identified — it was the creak of rusty iron, like a lever scraping in its slot. Instinctively action followed recognition so spontaneously that sound, impulse and action were practically simultaneous. And as his prodigious bound carried him backward, there was the rush of a great bulk from above, and a thunderous crash filled the tunnel with deafening vibrations. Bits of flying splinters struck him — a huge block of stone, he knew from the sound, dropped on the spot he had just quitted. An instant’s slower thought or action and it would have crushed him like an ant.
Conan fell back. Somewhere on the other side of that metal door Muriela was a captive, if she still lived. But he could not pass that door, and if he remained in the tunnel another block might fall, and he might not be so lucky. It would do the girl no good for him to be crushed into a purple pulp. He could not continue his search in that direction. He must get above ground and look for some other avenue of approach.
He turned and hurried toward the stair, sighing as he emerged into comparative radiance. And as he set foot on the first step, the light was blotted out, and above him the marble door rushed shut with a resounding reverberation.
Something like panic seized the Cimmerian then, trapped in that black tunnel, and he wheeled on the stair, lifting his sword and glaring murderously into the darkness behind him, expecting a rush of ghoulish assailants. But there was no sound or movement down the tunnel. Did the men beyond the door — if they were men — believe that he had been disposed of by the fall of the stone from the roof, which had undoubtedly been released by some sort of machinery?
