Cleves also rose.
Sansa laughed noiselessly: "My lord would go whither thou goest, Heart of Fire!" she whispered. "And thy ways shall be his ways!"
Tressa's cheeks flamed and she turned and looked at Cleves.
Then Sansa rose and laid a hand on Tressa's arm and on her husband's:
"Listen attentively. Tiyang Khan must be destroyed. The signal sounds when my lord's rifle-shot makes a loud noise here among these trees."
"Can I prevail against the Tchor-Dagh?" asked Tressa, steadily.
"Is not that event already in God's hands, darling?" said Sansa softly. She smiled and resumed her seat beside Selden, amid the drooping fern fronds.
"Bid thy dear lord leave his rifle here," she added quietly.
Cleves laid down his weapon. Selden pointed eastward in silence.
So they went together into the darkening woods.
In the dusk of heavy foliage overhanging the garden, Tressa lay flat as a lizard on the top of the wall. Beside her lay her husband.
In the garden below them flowers bloomed in scented thickets, bordered by walks of flat stone slabs split from boulders. A little lawn, very green, centred the garden.
And on this lawn, in the clear twilight still tinged with the sombre fires of sundown, squatted a man dressed in a loose white garment.
Save for a twisted breadth of white cloth, his shaven head was bare. His sinewy feet were naked, too, the lean, brown toes buried in the grass.
Tressa's lips touched her husband's ear.
"Tiyang Khan," she breathed. "Watch what he does!"
Shoulder to shoulder they lay there, scarcely daring to breathe. Their eyes were fastened on the Mongol Sorcerer, who, squatted below on his haunches, grave and deliberate as a great grey ape, continued busy with the obscure business which so intently preoccupied him.
In a short semi-circle on the grass in front of him he had placed a dozen wild Ginseng roots. The roots were enormous, astoundingly shaped like the human body, almost repulsive in their weird symmetry.
The Yezidee had taken one of these roots into his hands. Squatting there in the semi-dusk, he began to massage it between his long, muscular fingers, rubbing, moulding, pressing the root with caressing deliberation.
His unhurried manipulation, for a few moments, seemed to produce no result. But presently the Ginseng root became lighter in colour and more supple, yielding to his fingers, growing ivory pale, sinuously limber in a newer and more delicate symmetry.
"Look!" gasped Cleves, grasping his wife's arm. "What is that man doing?"
"The Tchor-Dagh!" whispered Tressa. "Do you see what lies twisting there in his hands?"
The Ginseng root had become the tiny naked body of a woman – a little ivory-white creature, struggling to escape between the hands that had created it – dark, powerful, masterly hands, opening leisurely now, and releasing the living being they had fashioned.
The thing scrambled between the fingers of the Sorcerer, leaped into the grass, ran a little way and hid, crouched down, panting, almost hidden by the long grass. The shocked watchers on the wall could still see the creature. Tressa felt Cleves' body trembling beside her. She rested a cool, steady hand on his.
"It is the Tchor-Dagh," she breathed close to his face. "The Mongol Sorcerer is becoming formidable."
"Oh, God!" murmured Cleves, "that thing he made is alive! I saw it. I can see it hiding there in the grass. It's frightened – breathing! It's alive!"
His pistol, clutched in his right hand, quivered. His wife laid her hand on it and cautiously shook her head.
"No," she said, "that is of no use."
"But what that Yezidee is doing is – is blasphemous – "
"Watch him! His mind is stealthily feeling its way among the laws and secrets of the Tchor-Dagh. He has found a thread. He is following it through the maze into hell's own labyrinth! He has created a tiny thing in the image of the Creator. He will try to create a larger being now. Watch him with his Ginseng roots!"
Tiyang, looming ape-like on his haunches in the deepening dusk, moulded and massaged the Ginseng roots, one after another. And one after another, tiny naked creatures wriggled out of his palms between his fingers and scuttled away into the herbage.
Already the dim lawn was alive with them, crawling, scurrying through the grass, creeping in among the flower-beds, little, ghostly-white things that glimmered from shade into shadow like moonbeams.
Tressa's mouth touched her husband's ear:
"It is for the secret of Destruction that the Yezidee seeks. But first he must learn the secret of creation. He is learning… And he must learn no more than he has already learned."
"That Yezidee is a living man. Shall I fire?"
"No."
"I can kill him with the first shot."
"Hark!" she whispered excitedly, her hand closing convulsively on her husband's arm.
The whip-crack of a rifle-shot still crackled in their ears.
Tiyang had leaped to his feet in the dusk, a Ginseng root, half-alive, hanging from one hand and beginning to squirm.
Suddenly the first moonbeam fell across the wall. And in its lustre Tressa rose to her knees and flung up her right hand.
Then it was as though her palm caught and reflected the moon's ray, and hurled it in one blinding shaft straight into the dark visage of Tiyang-Khan.
The Yezidee fell as though he had been pierced by a shaft of steel, and lay sprawling there on the grass in the ghastly glare.
And where his features had been there gaped only a hole into the head.
Then a dreadful thing occurred; for everywhere the grass swarmed with the little naked creatures he had made, running, scrambling, scuttling, darting into the black hole which had been the face of Tiyang-Khan.
They poured into the awful orifice, crowding, jostling one another so violently that the head jerked from side to side on the grass, a wabbling, inert, soggy mass in the moonlight.
And presently the body of Tiyang-Khan, Warden of the Rampart of Gog and Magog, and Lord of the Seventh Tower, began to burn with white fire – a low, glimmering combustion that seemed to clothe the limbs like an incandescent mist.
On the wall knelt Tressa, the glare from her lifted hand streaming over the burning form below.
Cleves stood tall and shadowy beside his wife, the useless pistol hanging in his grasp.
Then, in the silence of the woods, and very near, they heard Sansa laughing. And Selden's anxious voice:
