Steve's hair prickled. He knew that Yar Ali 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 hairy 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.
