Chapter II

WHEN GORDON LEFT the camp he did not look behind him. Any thoughts of treachery on the part of his companions was furthest from his mind. He had no reason to suppose that they were anything except what they had represented themselves to be--white men taking a long chance to find a comrade the unmapped solitudes had swallowed up.
It was an hour or so after leaving the camp when, skirting the end of a grassy ridge, he sighted an antelope moving along the fringe of a thicket. The wind, such as there was, was blowing toward him, away from the animal. He began stalking it through the thicket, when a movement in the bushes behind him brought him around to the realization that he himself was being stalked.
He had a glimpse of a figure behind a clump of scrub, and then a bullet fanned his ear, and he fired at the flash and the puff of smoke. There was a thrashing among the foliage and then stillness. A moment later he was bending over a picturesquely clad form on the ground.
It was a lean, wiry man, young, with an ermine-edged khilat, a fur calpack, and silver-heeled boots. Sheathed knives were in his girdle, and a modern repeating rifle lay near his hand. He had been shot through the heart.
"Turkoman," muttered Gordon. "Bandit, from his looks, out on a lone scout. I wonder how far he's been trailing me."
He knew the presence of the man implied two things: somewhere in the vicinity there was a band of Turkomans; and somewhere, probably close by, there was a horse. A nomad never walked far, even when stalking a victim. He glanced up at the rise which rolled up from the copse. It was logical to believe that the Moslem had sighted him from the crest of the low ridge, had tied his horse on the other side, and glided down into the thicket to waylay him while he stalked the antelope.
Gordon went up the slope warily, though he did not believe there were any other tribesmen within earshot--else the reports of the rifles would have brought them to the spot--and found the horse without trouble. It was a Turkish stallion with a red leather saddle with wide silver stirrups and a bridle heavy with goldwork. A scimitar hung from the saddle peak in an ornamented leather scabbard.
Swinging into the saddle, Gordon studied all quarters of the compass from the summit of the ridge. In the south a faint ribbon of smoke stood against the evening. His black eyes were keen as a hawk's; not many could have distinguished that filmy blue feather against the cerulean of the sky.
"Turkoman means bandits," he muttered. "Smoke means camp. They're trailing us, sure as fate."
Reining about, he headed for the camp. His hunt had carried him some miles east of the site, but he rode at a pace that ate up the distance. It was not yet twilight when he halted in the fringe of the larches and sat silently scanning the slope on which the camp had stood. It was bare. There was no sign of tents, men, or beasts.
His gaze sifted the surrounding ridges and clumps, but found nothing to rouse his alert suspicion. At last he walked his steed up the acclivity, carrying his rifle at the ready. He saw a smear of blood on the ground where he knew Pembroke's tent had stood, but there was no other sign of violence, and the grass was not trampled as it would have been by a charge of wild horsemen.
He read the evidence of a swift but orderly exodus. His companions had simply struck their tents, loaded the pack animals, and departed. But why? Sight of distant horsemen might have stampeded the white men, though neither had shown any sign of the white feather before; but certainly Ahmed would not have deserted his master and friend.
As he traced the course of the horses through the grass, his puzzlement increased; they had gone westward.
Their avowed destination lay beyond those mountains in the north. They knew that, as well as he. But there was no mistake about it. For some reason, shortly after he had left camp, as he read the signs, they had packed hurriedly and set off westward, toward the forbidden country identified by Mount Erlik.
Thinking that possibly they had a logical reason for shifting camp and had left him a note of some kind which he had failed to find, Gordon rode back to the camp site and began casting about it in an ever-widening circle, studying the ground. And presently he saw sure signs that a heavy body had been dragged through the grass.
Men and horses had almost obliterated the dim track, but for years Gordon's life had depended upon the keenness of his faculties. He remembered the smear of blood on the ground where Pembroke's tent had stood.
He followed the crushed grass down the south slope and into a thicket, and an instant later he was kneeling beside the body of a man. It was Ahmed, and at first glance Gordon thought he was dead. Then he saw that the Punjabi, though shot through the body and un-doubtedly dying, still had a faint spark of life in him.
He lifted the turbaned head and set his canteen to the blue lips. Ahmed groaned, and into his glazed eyes came intelligence and recognition.
"Who did this, Ahmed?" Gordon's voice grated with the suppression of his emotions.
"Ormond Sahib," gasped the Punjabi. "I listened outside their tent, because I feared they planned treachery to you. I never trusted them. So they shot me and have gone away, leaving you to die alone in the hills."
"But why?" Gordon was more mystified than ever.
"They go to Yolgan," panted Ahmed. "The Reynolds Sahib we sought never existed. He was a lie they created to hoodwink you."
"Why to Yolgan?" asked Gordon.
But Ahmed's eyes dilated with the imminence of death; in a racking convulsion he heaved up in Gordon's arms; then blood gushed from his lips and he died.

Gordon rose, mechanically dusting his hands. Immobile as the deserts he haunted, he was not prone to display his emotions. Now he merely went about heaping stones over the body to make a cairn that wolves and jackals could not tear into. Ahmed had been his companion on many a dim road; less servant than friend.
But when he had lifted the last stone, Gordon climbed into the saddle, and without a backward glance he rode westward. He was alone in a savage country, without food or proper equipage. Chance had given him a horse, and years of wandering on the raw edges of the world had given him experience and a greater familiarity with this unknown land than any other white man he knew. It was conceivable that he might live to win his way through to some civilized outpost.
But he did not even give that possibility a thought. Gordon's ideas of obligation, of debt and payment, were as direct and primitive as those of the barbarians among whom his lot had been cast for so many years. Ahmed had been his friend and had died in his service. Blood must pay for blood.
That was as certain in Gordon's mind as hunger is certain in the mind of a gray timber wolf. He did not know why the killers were going toward forbidden Yolgan, and he did not greatly care. His task was to follow them to hell if necessary and exact full payment for spilled blood. No other course suggested itself.
Darkness fell and the stars came out, but he did not slacken his pace. Even by starlight it was not hard to follow the trail of the caravan through the high grass. The Turkish horse proved a good one and fairly fresh. He felt certain of overtaking the laden pack ponies, in spite of their long start.
As the hours passed, however, he decided that the Englishmen were determined to push on all night. They evidently meant to put so much distance between them and himself that he could never catch them, following on foot as they thought him to be. But why were they so anxious to keep from him the truth of their destination?
A sudden thought made his face grim, and after that he pushed his mount a bit harder. His hand instinctively sought the hilt of the broad scimitar slung from the high-peaked horn.
His gaze sought the white cap of Mount Erlik, ghostly in the starlight, then swung to the point where he knew Yolgan lay. He had been there before, himself, had heard the deep roar of the long bronze trumpets that shaven-headed priests blow from the mountains at sunrise.
It was past midnight when he sighted fires near the willow-massed banks of a stream. At first glance he knew it was not the camp of the men he followed. The fires were too many. It was an ordu of the nomadic Kirghiz who roam the country between Mount Erlik Khan and the loose boundaries of the Mohammedan tribes. This camp lay full in the path of Yolgan and he wondered if the Englishmen had known enough to avoid it. These fierce people hated strangers. He himself, when he visited Yolgan, had accomplished the feat disguised as a native.
Gaining the stream above the camp he moved closer, in the shelter of the willows, until he could make out the dim shapes of sentries on horseback in the light of the small fires. And he saw something else--three white European tents inside the ring of round, gray felt kibitkas. He swore silently; if the Black Kirghiz had killed the white men, appropriating their belongings, it meant the end of his vengeance. He moved nearer.
It was a suspicious, slinking, wolf-like dog that betrayed him. Its frenzied clamor brought men swarming out of the felt tents, and a swarm of mounted sentinels raced toward the spot, stringing bows as they came.
Gordon had no wish to be filled with arrows as he ran. He spurred out of the willows and was among the horsemen before they were aware of him, slashing silently right and left with the Turkish scimitar. Blades swung around him, but the men were more confused than he. He felt his edge grate against steel and glance down to split a broad skull; then he was through the cordon and racing into deeper darkness while the demoralized pack howled behind him.
A familiar voice shouting above the clamor told him that Ormond, at least, was not dead. He glanced back to see a tall figure cross the firelight and recognized Pembroke's rangy frame. The fire gleamed on steel in his hands. That they were armed showed they were not prisoners, though this forbearance on the part of the fierce nomads was more than his store of Eastern lore could explain.
The pursuers did not follow him far; drawing in under the shadows of a thicket he heard them shouting gutturally to each other as they rode back to the tent. There would be no more sleep in that ordu that night. Men with naked steel in their hands would pace their horses about the encampment until dawn. It would be difficult to steal back for a long shot at his enemies. But now, before he slew them, he wished to learn what took them to Yolgan.
Absently his hand caressed the hawk-headed pommel of the Turkoman scimitar. Then he turned again eastward and rode back along the route he had come, as fast as he could push the wearying horse. It was not yet dawn when he came upon what he had hoped to find--a second camp, some ten miles west of the spot where Ahmed had been killed; dying fires reflected on one small tent and on the forms of men wrapped in cloaks on the ground.
He did not approach too near; when he could make out the lines of slowly moving shapes that were picketed horses and could see other shapes that were riders pacing about the camp, he drew back behind a thicketed ridge, dismounted and unsaddled his horse.
While it eagerly cropped the fresh grass, he sat cross-legged with his back to a tree trunk, his rifle across his knees, as motionless as an image and as imbued with the vast patience of the East as the eternal hills themselves.
