ened bones. The crisped hand still gripped the ivory sword-hilt, but the blade was gone—melted and destroyed by that awful heat. Yet men standing almost within reach of the victim had not suffered except to be dazzled and half blinded by the sudden flare.
"Steel touches it off,” grunted Conan. "Look out—here they come!”
The slope above them was almost covered by the billowing spheres. Kerim Shah bent his bow and sent a shaft into the mass, and those touched by the arrow burst like bubbles in spurting flame. His men followed his example and for the next few minutes it was as if a thunderstorm raged on the mountain slope, with bolts of lightning striking and bursting in showers of flame. When the barrage ceased, only a few arrows were left in the quivers of the archers.
They pushed on grimly, over soil charred and blackened, where the naked rock had in places been turned to lava by the explosion of those diabolical bombs.
Now they were almost within arrow-flight of the silent tower, and they spread their line, nerves taut, ready for any horror that might descend upon them.
On the tower appeared a single figure, lifting a ten-foot bronze horn. Its strident bellow roared out across the echoing slopes, like the blare of trumpets on Judgment Day. And it began to be fearfully answered. The ground trembled under the feet of the invaders, and rumblings and grindings welled up from the subterranean depths.
The Irakzai screamed, reeling like drunken men on the shuddering slope, and Conan, eyes glaring, charged recklessly up the incline, knife in hand, straight at the door that showed in the tower-wall. Above him the great horn roared and bellowed in brutish mockery. And then Kerim Shah drew a shaft to his ear and loosed.
Only a Turanian could have made that shot. The bellowing of the horn ceased suddenly, and a high, thin scream shrilled in its place. The green-robed figure on the tower staggered, clutching at the long shaft which quivered in its bosom, and then pitched across the parapet. The great horn tumbled upon the battlement and hung precariously, and another robed figure rushed to seize it, shrieking in horror. Again the Turanian bow twanged, and again it was answered by a death-howl. The second acolyte, in falling, struck the horn with his elbow and knocked it clattering over the parapet to shatter on the rocks far below.
At such headlong speed had Conan covered the ground that before the clattering echoes of that fall had died away, he was hacking at the door. Warned by his savage instinct, he gave back suddenly as a tide of molten lead splashed down from above. But the next instant he was back again, attacking the panels with redoubled fury. He was galvanized by the fact that his enemies had resorted to earthly weapons. The sorcery of the acolytes was limited. Their necromantic resources might well be exhausted.
Kerim Shah was hurrying up the slope, his hillmen behind him in a straggling crescent. They loosed as they ran, their arrows splintering against the walls or arching over the parapet.
The heavy teak portal gave way beneath the Cimmerian’s assault, and he peered inside warily, expecting anything. He was looking into a circular chamber from which a stair wound upward. On the opposite side of the chamber a door gaped open, revealing the outer slope—and the backs of half a dozen green-robed figures in full retreat.
