"Thereat the great stone cried out as a live thing cries, and the king and his soldiers saw a black cloud spinning up from the floor, and out of the cloud blew a fetid wind, and out of the wind came a grisly shape which stretched forth fearsome paws and laid them on the king, who shriveled and died at their touch. And the soldiers fled screaming, and all the people of the city ran forth wailing into the desert, where they perished or gained through the wastes to the far oasis towns. Kara-Shehr lay silent and deserted, the haunt of the lizard and the jackal. And when some of the desert-people ventured into the city they found the king dead on his throne, clutching the blazing gem, but they dared not lay hand upon it, for they knew the demon lurked near to guard it through all the ages--as he lurks near even as we stand here." The warriors shuddered involuntarily and glanced about, and Nureddin said, "Why did he not come forth when the Franks entered the chamber? Is he deaf, that the sound of the combat has not awakened him?" "We have not touched the gem," answered the old Bedouin, "nor had the Franks molested it. Men have looked on it and lived; but no mortal may touch it and survive." * * * * * Nureddin started to speak, gazed at the stubborn, uneasy faces and realized the futility of argument. His attitude changed abruptly. "I am master here," he snapped, dropping a hand to his holster. "I have not sweat and bled for this gem to be balked at the last by groundless fears! Stand back, all! Let any man cross me at the peril of his head!" He faced them, his eyes blazing, and they fell back, cowed by the force of his ruthless personality. He strode boldly up the marble steps, and the Arabs caught their breath, recoiling toward the door; Yar Ali, conscious at last, groaned dismally. God! thought Steve, what a barbaric scene!--bound captives on the dust-heaped floor, wild warriors clustered about, gripping their weapons, the raw acrid scent of blood and burnt powder still fouling the air, corpses strewn in a horrid welter of blood, brains and entrails--and on the dais, the hawk-faced shaykh, oblivious to all except the evil crimson glow in the skeleton fingers that rested on the marble throne. A tense silence gripped all as Nureddin stretched forth his hand slowly, as if hypnotized by the throbbing crimson light. And in Steve's subconsciousness there shuddered a dim echo, as of something vast and loathsome waking suddenly from an age-long slumber. The American's eyes moved instinctively toward the grim cyclopean walls. The jewel's glow had altered strangely; it burned a deeper, darker red, angry and menacing.
