Their architecture was repellent; of high skill, yet so massive, sullen and brutish in effect as to be almost beyond the comprehension of moderns.
The adventurers passed through a narrow door which opened in the end of the hall close to the idol, and came into a series of wide, dim, dusty chambers connected by column-flanked corridors. Along these they strode in the gray ghostly light, and came at last to a wide stair, whose massive stone steps led upward and vanished in the gloom. Here Yar Ali halted.
"We have dared much, sahib," he muttered. "Is it wise to dare more?"
Steve, aquiver with eagerness, yet understood the Afghan's mind. "You mean we shouldn't, go up those stairs?"
"They have an evil look. To what chambers of silence and horror may they lead? When djinn haunt deserted buildings, they lurk in the upper chambers. At any moment a demon may bite off our heads."
"We're dead men anyhow," grunted Steve. "But I tell you—you go on back through the hall and watch for the Arabs while I go upstairs."
"Watch for a wind on the horizon," responded the Afghan gloomily, shifting his rifle and loosening his long knife in its scabbard. "No Bedouin comes here. Lead on, sahib. Thou'rt mad after the manner of all Franks,—but I would not leave thee to face the djinn alone."
So the companions mounted the massive stairs, their feet sinking deep into the accumulated dust of centuries at each step. Up and up they went, to an incredible height until the depths below merged into a vague gloom.
"We walk blind to our doom, sahib," muttered Yar Ali. "Allah il allah —and Muhammad is his Prophet! Nevertheless, I feel the presence of slumbering Evil and never again shall I hear the wind blowing up the Khyber Pass."
Steve made no reply. He did not like the breathless silence that brooded over the ancient temple, nor the grisly gray light that filtered from some hidden source.
Now above them the gloom lightened somewhat and they emerged into a vast circular chamber, grayly illumined by light that filtered in through the high, pierced ceiling. But another radiance lent itself to the illumination. A cry burst from Steve's lips, echoed by Yar Ali.
Standing on the top step of the broad stone stair, they looked directly across the broad chamber, with its dustcovered heavy tile floor and bare black stone walls. From about the center of the chamber, massive steps led up to a stone dais, and on this dais stood a marble throne. About this throne glowed and shimmered an uncanny light, and the awestruck adventurers gasped as they saw its source. On the throne slumped a human skeleton, an almost shapeless mass of moldering bones. A fleshless hand sagged outstretched upon the broad marble throne-arm, and in its grisly clasp there pulsed and throbbed like a living thing, a great crimson stone.
The Fire of Asshurbanipal! Even after they had found the lost city Steve had not really allowed himself to believe that they would find the gem, or that it even existed in reality. Yet he could not doubt the evidence of his eyes, dazzled by that evil, incredible glow. With a fierce shout he sprang across the chamber and up the steps. Yar All was at his heels, but when Steve would have seized the gem, the Afghan laid a hand on his arm.
"Wait!" exclaimed the big Muhammadan. "Touch it not yet, sahib! A curse lies on ancient things—and surely this is a thing triply accursed! Else why has it lain here untouched in a country of thieves for so many centuries? It is not well to disturb the possessions of the dead."
"Bosh!" snorted the American. "Superstitions! The Bedouins were scared by the tales that have come down to 'em from their ancestors. Being desert- dwellers they mistrust cities anyway, and no doubt this one had an evil reputation in its lifetime. And nobody except Bedouins have seen this place before, except that Turk, who was probably half demented with suffering.
"These bones may be those of the king mentioned in the legend—the dry desert air preserves such things indefinitelybut I doubt it. May be Assyrian—most likely Arab—some beggar that got the gem and then died on that throne for some reason or other."
The Afghan scarcely heard him. He was gazing in fearful fascination at the great stone, as a hypnotized bird stares into a serpent's eye.
"Look at it, sahib!" he whispered. "What is it? No such gem as this was ever cut by. mortal hands! Look how it throbs and pulses like the heart of a cobra!"
Steve was looking, and he was aware of a strange undefined feeling of uneasiness. Well versed in the knowledge of precious stones, he had never seen a stone like this. At first glance he had supposed it to be a monster ruby, as told in the legends. Now he was not sure, and he had a nervous feeling that Yar Ali was right, that this was no natural, normal gem: He could not classify the style in which it was cut, and such was the power of its lurid radiance that he found it difficult to gaze at it closely for any length of time. The whole setting was not one calculated to soothe restless nerves. The deep dust on the floor suggested an unwholesome antiquity; the gray light evoked a sense of unreality, and the heavy black walls towered grimly, hinting at hidden things.
"Let's take the stone, and go!" muttered Steve, an unaccustomed panicky dread rising in his bosom.
"Wait!" Yar Ali's eyes were blazing, and he gazed, not at the gem, but at the sullen stone walls. "We are flies in the lair of the spider! Sahib, as Allah lives, it is more than the ghosts of old fears that lurk over this city of horror! I feel the presence of peril, as I have felt it before—as I felt it in a jungle cavern where a python lurked unseen in—the darkness —as I felt it in the temple of Thuggee where the hidden stranglers of Siva crouched to spring upon us—as I feel it now, tenfold!"
Steve's hair prickled. He knew that Yar All was a grim veteran, not to be stampeded by silly fear or senseless panic; he well remembered the incidents referred to by the Afghan, as he remembered other occasions upon which Yar Ali's Oriental telepathic instinct had warned him of danger before that danger was seen or heard.
"What is it, Yar Ali?" he whispered.
The Afghan shook his head, his eyes filled with a weird mysterious light as he listened to the dim occult promptings of his subconsciousness.
"I know not; I know it is close to us, and that it is very ancient and very evil. I think—" Suddenly he halted and wheeled, the eery light vanishing from his eyes to be replaced by a glare of wolf-like fear and suspicion.
"Hark, sahib!" he snapped. "Ghosts or dead men mount the stair!"
Steve stiffened as the stealthy pad of soft sandals on stone reached his ear.
"By Judas, Ali!" he rapped; "something's out there—"
The ancient walls re-echoed to a chorus of wild yells as a horde of savage figures flooded the chamber. For one dazed insane instant Steve believed wildly that they were being attacked by re-embodied warriors of a vanished age; then the spiteful crack of a bullet past his ear and the acrid smell of powder told him that their foes were material enough. Clarney cursed; in their fancied security—they had been caught like rats in a trap by the pursuing Arabs.
Even as the American threw up his rifle, Yar Ali fired point-blank from the hip with deadly effect, hurled his empty rifle into the horde and went down the steps like a hurricane, his three-foot Khyber knife shimmering in his hairv hand. Into his gusto for battle went real relief that his foes were human. A bullet ripped the turban from his head, but an Arab went down with a split skull beneath the hillman's first, shearing stroke.
A tall Bedouin clapped his gun-muzzle to the Afghan's side, but before he could pull the trigger, Clarney's bullet scattered his brains. The very number of the attackers hindered their onslaught on the big Afridi, whose tigerish quickness made shooting as dangerous to themselves as to him. The bulk of them swarmed about him, striking with scimitar and rifle-stock while others charged up the steps after Steve. At that range there was no missing; the American simply thrust his rifle muzzle into a bearded face and blasted it into a ghastly ruin. The others came on, screaming like panthers.
