"It is already accomplished," the Mongol asserted imperturbably. "The executioner has gone to him, and by this time Mr. Harrison's head resembles a crushed egg."
"Oh, God!" At the sick grief and pain in that moan Harrison winced and fought a frantic desire to shout out denial and reassurance.
Then she remembered something else to torture her.
"Khoda Khan! What have you done with Khoda Khan?"
The Afghan's fingers clamped like iron on Harrison's arm at the sound of his name.
"When my men brought you away they did not take time to deal with him," replied the Mongol. "They had not expected to take you alive, and when fate cast you into their hands, they came away in haste. He matters little. True, he killed four of my best men, but that was merely the deed of a wolf. He has no mentality. He and the detective are much alike—mere masses of brawn, brainless, helpless against intellect like mine. Presently I shall attend to him. His corpse shall be thrown on a dung-heap with a dead pig."
"Allah!" Harrison felt Khoda Khan trembling with fury. "Liar! I will feed his yellow guts to the rats!"
Only Harrison's grip on his arm kept the maddened Moslem from attacking the stone wall in an effort to burst through to his enemy. The detective was running his hand over the surface, seeking a door, but only blank stone rewarded him. Erlik Khan had not had time to provide his unfinished house with as many secrets as his rat-runs usually possessed.
They heard the Mongol clap his hands authoritatively, and they sensed the entrance of men into the room. Staccato commands followed in Mongolian, there was a sharp cry of pain or fear, and then silence followed the soft closing of a door. Though they could not see, both men knew instinctively that the chamber on the other side of the wall was empty. Harrison almost strangled with a panic of helpless rage. He was penned in these infernal walls and Joan La Tour was being borne away to some abominable doom.
"Wallah!" the Afghan was raving. "They have taken her away to slay her! Her life and our izzat is at stake! By the Prophet's beard and my feet! I will burn this accursed house! I will slake the fire with Mongol blood! In Allah's name, sahib, let us do something!"
"Come on!" snarled Harrison. "There must be another door somewhere!"
Recklessly they plunged down the winding stair, and about the time they had reached the first floor level, Harrison's groping hand felt a door. Even as he found the catch, it moved under his fingers. Their noise must have been heard through the wall, for the panel opened, and a shaven head was poked in, framed in the square of light. The Mongol blinked in the darkness, and Harrison brought the mace down on his head, experiencing a vengeful satisfaction as he felt the skull give way beneath the iron spikes. The man fell face down in the narrow opening and Harrison sprang over his body into the outer room before he took time to learn if there were others. But the chamber was untenanted. It was thickly carpeted, the walls hung with black velvet tapestries. The doors were of bronze-bound teak, with gilt-worked arches. Khoda Khan presented an incongruous contrast, bare-footed, with draggled turban and red-smeared knife.
But Harrison did not pause to philosophize. Ignorant as he was of the house, one way was as good as another. He chose a door at random and flung it open, revealing a wide corridor carpeted and tapestried like the chamber. At the other end, through wide satin curtains that hung from roof to floor, a file of men was just disappearing—tall, black-silk clad Mongols, heads bent somberly, like a train of dusky ghosts. They did not look back.
"Follow them!" snapped Harrison. "They must be headed for the execution—"
Khoda Khan was already sweeping down the corridor like a vengeful whirlwind. The thick carpet deadened their footfalls, so even Harrison's big shoes made no noise. There was a distinct feeling of unreality, running silently down that fantastic hall—it was like a dream in which natural laws are suspended. Even in that moment Harrison had time to reflect that this whole night had been like a nightmare, possible only in the Oriental quarter, its violence and bloodshed like an evil dream. Erlik Khan had loosed the forces of chaos and insanity; murder had gone mad, and its frenzy was imparted to all actions and men caught in its maelstrom.
Khoda Khan would have burst headlong through the curtains—he was already drawing breath for a yell, and lifting his knife—if Harrison had not seized him. The Afghan's sinews were like cords under the detective's hands, and Harrison doubted his own ability to restrain him forcibly, but a vestige of sanity remained to the hillman.
Pushing him back, Harrison gazed between the curtains. There was a great double-valved door there, but it was partly open, and he looked into the room beyond. Khoda Khan's beard was jammed hard against his neck as the Afghan glared over his shoulder.
It was a large chamber, hung like the others with black velvet on which golden dragons writhed. There were thick rugs, and lanterns hanging from the ivory-inlaid ceiling cast a red glow that made for illusion. Black-robed men ranged along the wall might have been shadows but for their glittering eyes.
On a throne-like chair of ebony sat a grim figure, motionless as an image except when its loose robes stirred in the faintly moving air. Harrison felt the short hairs prickle at the back of his neck, just as a dog's hackles rise at the sight of an enemy. Khoda Khan muttered some incoherent blasphemy.
The Mongol's throne was set against a side wall. No one stood near him as he sat in solitary magnificence, like an idol brooding on human doom. In the center of the room stood what looked uncomfortably like a sacrificial altar —a curiously carved block of stone that might have come out of the heart of the Gobi. On that stone lay Joan La Tour, white as a marble statue, her arms outstretched like a crucifix, her hands and feet extending over the edges of the block. Her dilated eyes stared upward as one lost to hope, aware of doom and eager only for death to put an end to agony. The physical torture had not yet begun, but a gaunt half-naked brute squatted on his haunches at the end of the altar, heating the point of a bronze rod in a dish full of glowing coals.
"Damn!" It was half curse, half sob of fury bursting from Harrison's lips. Then he was hurled aside and Khoda Khan burst into the room like a flying dervish, bristling beard, blazing eyes, knife and all. Erlik Khan came erect with a startled guttural as the Afghan came tearing down the room like a headlong hurricane of destruction. The torturer sprang up just in time to meet the yard-long knife lashing down, and it split his skull down through the teeth.
"Aie!" It was a howl from a score of Mongol throats.
"Allaho akabar!" yelled Khoda Khan, whirling the red knife about his head. He threw himself on the altar, slashing at Joan's bonds with a frenzy that threatened to dismember the girl.
Then from all sides the black-robed figures swarmed in, not noticing in their confusion that the Afghan had been followed by another grim figure who came with less abandon but with equal ferocity.
They were aware of Harrison only when he dealt a prodigious sweep of his mace, right and left, bowling men over like ten-pins, and reached the altar through the gap made in the bewildered throng. Khoda Khan had freed the girl and he wheeled, spitting like a cat, his bared teeth gleaming and each hair of his beard stiffly on end.
"Allah!" he yelled—spat in the faces of the oncoming Mongols —crouched as if to spring into the midst of them—then whirled and rushed headlong at the ebony throne.
The speed and unexpectedness of the move were stunning. With a choked cry Erlik Khan fired and missed at point-blank range—and then the breath burst from Khoda Khan in an ear-splitting yell as his knife plunged into the Mongol's breast and the point sprang a hand's breadth out of his black-clad back.
