A WIND BLEW over the shoulders of the peaks where the snow lay drifted, a knife-edge wind that slashed through leather and wadded cloth in spite of the searing sun. Stuart Brent blinked his eyes against the glare of that intolerable sun, shivered at the bite of the wind. He had no coat, and his shirt was tattered. For the thousandth futile, involuntary time, he wrenched at the fetters on his wrists. They jangled, and the man riding in front of him cursed, turned and struck him heavily in the mouth. Brent reeled in his saddle, blood starting to his lips.
The saddle chafed him, and the stirrups were too short for his long legs. He was riding along a knife-edge trail, in the middle of a straggling line of some thirty men-ragged men on gaunt, ribby horses. They rode hunched in their high-peaked saddles, turbaned heads thrust forward and nodding in unison to the clop-clop of their horses" hoofs, long-barreled rifles swaying across the saddlebows. On one hand rose a towering cliff; on the other, a sheer precipice fell away into echoing depths. The skin was worn from Brent's wrists by the rusty, clumsy iron manacles that secured them; he was bruised from the kicks and blows, faint with hunger and giddy with the enormousness of the altitude. His nose bled at times without having been struck. Ahead of them loomed the backbone of the gigantic range that had risen like a rampart before them for so many days.
Dizzily he reviewed the events of the weeks that stretched between the time he had carried Dick Stockton, dying, into his flat, and this unbelievable, yet painfully real moment. The intervening period of time might have been an unfathomable and unbridgeable gulf stretching between and dividing two worlds that had nothing in common save consciousness.
He had come to India on the first ship he could catch. Official doors had opened to him at the whispered password: "Remember the kites of Khoral Nulla!" His path had been smoothed by impressive-looking documents with great red seals, by cryptic orders barked over telephones, or whispered into attentive ears. He had moved smoothly northward along hitherto unguessed channels. He had glimpsed, faintly, some of the shadowy, mountainous machinery grinding silently and ceaselessly behind the scenes-the unseen, half-suspected cogwheels of the empire that girdles the world.
Mustached men with medals on their breasts had conferred with him as to his needs, and quiet men in civilian clothes had guided him on his way. But no one had asked him why he sought El Borak, or what message he bore. The password and the mention of Stockton had sufficed. His friend had been more important in the imperial scheme of things than Brent had ever realized. The adventure had seemed more and more fantastic as he progressed-a page out of the "Arabian Nights," as he blindly carried a dead man's message, the significance of which he could not even guess, to a mysterious figure lost in the mists of the hills; while, at a whispered incantation, hidden doors swung wide and enigmatic figures bowed him on his way. But all this changed in the North.
Gordon was not in Kabul. This Brent learned from the lips of no less than the ameer himself-wearing his European garments as if born to them, but with the sharp, restless eyes of a man who knows he is a pawn between powerful rivals, and whose nerves are worn thin by the constant struggle for survival. Brent sensed that Gordon was a staff on which the ameer leaned heavily. But neither king nor agents of empire could chain the American's roving foot, or direct the hawk flights of the man the Afghans called "El Borak," the "Swift."
And Gordon was gone-wandering alone into those naked hills whose bleak mysteries had long ago claimed him from his own kind. He might be gone a month, he might be gone a year. He might-and the ameer shifted uneasily at the possibility-never return. The crag-set villages were full of his blood enemies.
Not even the long arm of empire reached beyond Kabul. The ameer ruled the tribes after a fashion-with a dominance that dared not presume too far. This was the Country of the Hills, where law was hinged on the strong arm wielding the long knife.
Gordon had vanished into the Northwest. And Brent, though flinching at the grim nakedness of the Himalayas, did not hesitate or visualize an alternative. He asked for and received an escort of soldiers. With them he pushed on, trying to follow Gordon's trail through the mountain villages.
A week out of Kabul they lost all trace of him. To all effects Gordon had vanished into thin air. The wild, shaggy hillmen answered questions sullenly, or not at all, glaring at the nervous Kabuli soldiery from under black brows. The farther they got away from Kabul, the more open the hostility. Only once did a question evoke a spontaneous response, and that was a suggestion that Gordon had been murdered by hostile tribesmen. At that, sardonic laughter yelled up from the wild men-the fierce, mocking mirth of the hills. El Borak trapped by his enemies? Is the gray wolf devoured by the fat-tailed sheep? And another gust of dry, ironic laughter, as hard as the black crags that burned under a sun of liquid flame. Stubborn as his grandsire who had glimpsed a mirage of tree-fringed ocean shore across the scorching desolation of another desert, Brent groped on, at a blind venture, trying to pick up the cold scent, far past the point of safety, as the gray-faced soldiers warned him again and again. They warned him that they were far from Kabul, in a sparsely settled, rebellious, little-explored region, whose wild people were rebels to the ameer, and enemies to El Borak. They would have deserted Brent long before and fled back to Kabul, had they not feared the ameer's wrath.
Their forebodings were justified in the hurricane of rifle fire that swept their camp in a chill gray dawn. Most of them fell at the first volley that ripped from the rocks about them. The rest fought futilely, ridden over and cut down by the wild riders that materialized out of the gray. Brent knew the surprise had been the soldiers" fault, but he did not have it in his heart to curse them, even now. They had been like children, sneaking in out of the cold as soon as his back was turned, sleeping on sentry duty, and lapsing into slovenly and unmilitary habits as soon as they were out of sight of Kabul. They had not wanted to come, in the first place; a foreboding of doom had haunted them; and now they were dead, and he was a captive, riding toward a fate he could not even guess.
Four days had passed since that slaughter, but he still turned sick when he remembered it-the smell of powder and blood, the screams, the rending chop of steel. He shuddered at the memory of the man he had killed in that last rush, with his pistol muzzle almost in the bearded face that lunged at him beneath a lifted rifle butt. He had never killed a man before. He sickened as he remembered the cries of the wounded soldiers when the conquerors cut their throats. And over and over he wondered why he had been spared-why they had overpowered and fettered him, instead of killing him. His suffering had been so intense he often wished they had killed him outright.
He was allowed to ride, and he was fed grudgingly when the others ate. But the food was niggardly. He who had never known hunger was never without it now, a gnawing misery. His coat had been taken from him, and the nights were a long agony in which he almost froze on the hard ground, in the icy winds. He wearied unto death of the day-long riding over incredible trails that wound up and up until he felt as if he could reach out a hand-if his hands were free-and touch the cold, pale sky. He was kicked and beaten until the first fiery resentment and humiliation had been dissolved in a dull hurt that was only aware of the physical pain, not of the injury to his self-respect.
He did not know who his captors were. They did not deign to speak English to him, but he had picked up more than a smattering of Pashto on that long journey up the Khyber to Kabul, and from Kabul westward. Like many men who live by their wits, he had the knack of acquiring new languages. But all he learned from listening to their conversation was that their leader was called Muhammad ez Zahir, and their destiny was Rub el Harami.
Rub el Harami! Brent had heard it first as a meaningless phrase gasped from Richard Stockton's blue lips. He had heard more of it as he came northward from the hot plains of the Punjab-a city of mystery and evil, which no white man had ever visited except as a captive, and from which none had ever escaped. A plague spot, sprawled in the high, bare hills, almost fabulous, beyond the reach of the ameer--an outlaw city, whence the winds blew whispered tales too fantastic and hideous for credence, even in this Country of the Knife.
At times Brent's escort mocked him, their burning eyes and grimly smiling lips lending a sinister meaning to their taunt: "The Feringi goes to Rub el Harami!"
For the pride of race he stiffened his spine and set his jaw; he plumbed unsuspected depths of endurance-legacy of a clean, athletic life, sharpened by the hard traveling of the past weeks.
They crossed a rocky crest and dropped down an incline between ridges that tilted up for a thousand feet.
Far above and beyond them they occasionally glimpsed a notch in the rampart that was the pass over which they must cross the backbone of the range up which they were toiling. It was as they labored up a long slope that the solitary horseman appeared.
The sun was poised on the knife-edge crest of a ridge to the west, a blood-colored ball, turning a streak of the sky to flame. Against that crimson ball a horseman appeared suddenly, a centaur image, black against the blinding curtain. Below him every rider turned in his saddle, and rifle bolts clicked. It did not need the barked command of Muhammed ez Zahir to halt the troop. There was something wild and arresting about that untamed figure in the sunset that held every eye. The rider's head was thrown back, the horse's long mane streaming in the wind.
Then the black silhouette detached itself from the crimson ball and moved down toward them, details springing into being as it emerged from the blinding background. It was a man on a rangy black stallion who came down the rocky, pathless slope with the smooth curving flight of an eagle, the sure hoofs spurning the ground. Brent, himself a horseman, felt his heart leap into his throat with admiration for the savage steed.
But he almost forgot the horse when the rider pulled up before them. He was neither tall nor bulky, but a barbaric strength was evident in his compact shoulders, his deep chest, his corded wrists. There was strength, too, in the keen, dark face, and the eyes, the blackest Brent had even seen, gleamed with an inward fire such as the American had seen burn in the eyes of wild things-an indomitable wildness and an unquenchable vitality. The thin, black mustache did not hide the hard set of the mouth.
The stranger looked like a desert dandy beside the ragged men of the troop, but it was a dandyism definitely masculine, from the silken turban to the silver-heeled boots. His bright-hued robe was belted with a gold-buckled girdle that supported a Turkish saber and a long dagger. A rifle jutted its butt from a scabbard beneath his knee.
Thirty-odd pairs of hostile eyes centered on him, after suspiciously sweeping the empty ridges behind him as he galloped up before the troop and reined his steed back on its haunches with a flourish that set the gold ornaments jingling on curb chains and reins. An empty hand was flung up in an exaggerated gesture of peace. The rider, well poised and confident, carried himself with a definite swagger.
"What do you want?" growled Muhammad ez Zahir, his cocked rifle covering the stranger.
"A small thing, as Allah is my witness!" declared the other, speaking Pashto with an accent Brent had never heard before. "I am Shirkuh, of Jebel Jawur. I ride to Rub el Harami. I wish to accompany you."
"Are you alone?" demanded Muhammad.
"I set forth from Herat many days ago with a party of camel men who swore they would guide me to Rub el Harami. Last night they sought to slay and rob me. One of them died suddenly. The others ran away, leaving me without food or guides. I lost my way, and have been wandering in the mountains all last night and all this day. Just now, by the favor of Allah, I sighted your band."
"How do you know we are bound for Rub el Harami?" demanded Muhammad.
"Are you not Muhammad ez Zahir, the prince of swordsmen?" countered Shirkuh.
The Afghan's beard bristled with satisfaction. He was not impervious to flattery. But he was still suspicious.
"You know me, Kurd?"
"Who does not know Muhammad ez Zahir? I saw you in the suk of Teheran, years ago. And now men say you are high in the ranks of the Black Tigers."
"Beware how your tongue runs, Kurd!" responded Muhammad. "Words are sometimes blades to cut men's throats. Are you sure of a welcome in Rub el Harami?"
"What stranger can be sure of a welcome there?" Shirkuh laughed. "But there is Feringi blood on my sword, and a price on my head. I have heard that such men were welcome in Rub el Harami."
"Ride with us if you will," said Muhammad. "I will get you through the Pass of Nadir Khan. But what may await you at the city gates is none of my affair. I have not invited you to Rub el Harami. I accept no responsibility for you."
"I ask for no man to vouch for me," retorted Shirkuh, with a glint of anger, brief and sharp, like the flash of hidden steel struck by a flint and momentarily revealed. He glanced curiously at Brent.
"Has there been a raid over the border?" he asked.
"This fool came seeking someone," scornfully answered Muhammad. "He walked into a trap set for him."
"What will be done with him in Rub el Harami?" pursued the newcomer, and Brent's interest in the conversation suddenly became painfully intense.
"He will be placed on the slave block," answered Muhammad, "according to the age-old custom of the city. Who bids highest will have him."
And so Brent learned the fate in store for him, and cold sweat broke out on his flesh as he contemplated a life spent as a tortured drudge to some turbaned ruffian. But he held up his head, feeling Shirkuh's fierce eyes upon him.
The stranger said slowly: "It may be his destiny to serve Shirkuh, of the Jebel Jawur! I never owned a slave-but who knows? It strikes my fancy to buy this Feringi!"
Brent reflected that Shirkuh must know that he was in no danger of being murdered and robbed, or he would never so openly imply possession of money. That suggested that he knew these were picked men, carrying out someone's instructions so implicitly that they could be depended on not to commit any crime not included in those orders. That implied organization and obedience beyond the conception of any ordinary hill chief. He was convinced that these men belonged to that mysterious cult against which Stockton had warned him-the Black Tigers. Then had their capture of him been due merely to chance? It seemed improbable.
"There are rich men in Rub el Harami, Kurd," growled Muhammad. "But it may be that none will want this Feringi and a wandering vagabond like you might buy him. Who knows?"
"Only in Allah is knowledge," agreed Shirkuh, and swung his horse into line behind Brent, crowding a man out of position and laughing when the Afghan snarled at him.
The troop got into motion, and a man leaned over to strike Brent with a rifle butt. Shirkuh checked the stroke. His lips laughed, but there was menace in his eyes.
"Nay! This infidel may belong to me before many days, and I will not have his bones broken!"
The man growled, but did not press the matter, and the troop rode on. They toiled up a ridge in a long shadow cast by the crag behind which the sun had sunk, and came into a valley and the sight of the sun again, just sinking behind a mountain. As they went down the slope, they spied white turbans moving among the crags to the west, and Muhammad ez Zahir snarled in suspicion at Shirkuh.
"Are they friends of yours, you dog? You said you were alone!"
"I know them not!" declared Shirkuh. Then he dragged his rifle from its boot. "The dogs fire on us!" For a tiny tongue of fire had jetted from among the boulders in the distance, and a bullet whined overhead.
"Hill-bred dogs who grudge us the use of the well ahead!" said Muhammad ez Zahir. "Would we had time to teach them a lesson! Hold your fire, you dogs! The range is too long for either they or us to do damage."
But Shirkuh wheeled out of the line of march and rode toward the foot of the ridge. Half a dozen men broke cover, high up on the slope, and dashed away over the crest, leaning low and spurring hard. Shirkuh fired once, then took steadier aim and fired three shots in swift succession.
"You missed!" shouted Muhammad angrily. "Who could hit at such a range?"
"Nay!" yelled Shirkuh. "Look!"
One of the ragged white shapes had wavered and pitched forward on its pony's neck. The beast vanished over the ridge, its rider lolling limply in the saddle.
"He will not ride far!" exulted Shirkuh, waving his rifle over his head as he raced back to the troop. "We Kurds have eyes like mountain hawks!"
"Shooting a Pathan hill thief does not make a hero," snapped Muhammad, turning disgustedly away.
But Shirkuh merely laughed tolerantly, as one so sure of his fame that he could afford to overlook the jealousies of lesser souls.
They rode on down into the broad valley, seeing no more of the hillmen. Dusk was falling when they halted beside the well. Brent, too stiff to dismount, was roughly jerked off his horse. His legs were bound, and he was allowed to sit with his back against a boulder just far enough away from the fires they built to keep him from benefiting any from the heat. No guard was set over him at present.
Presently Shirkuh came striding over to where the prisoner gnawed at the wretched crusts they allowed him. Shirkuh walked with a horseman's roll, setting his booted legs wide. He carried an iron bowl of stewed mutton, and some chupatties.
"Eat, Feringi!" he commanded roughly, but not harshly. "A slave whose ribs jut through his hide is no good to work or to fight. These niggardly Pathans would starve their grandfathers. But we Kurds are as generous as we are valiant!"
He offered the food with a gesture as of bestowing a province. Brent accepted it without thanks, and ate voraciously. Shirkuh had dominated the drama ever since he had entered it-a swashbuckler who swaggered upon the stage and would not be ignored. Even Muhammad ez Zahir was overshadowed by the overflowing vitality of the man. Shirkuh seemed a strange mixture of brutal barbarian and unsophisticated youth. There was a boyish exuberance in his swagger, and he displayed touches of naive simplicity at times. But there was nothing childish about his glittering black eyes, and he moved with a tigerish suppleness that Brent knew could be translated instantly into a blur of murderous action.
Shirkuh thrust his thumbs in his girdle now and stood looking down at the American as he ate. The light from the nearest fire of dry tamarisk branches threw his dark face into shadowy half relief and gave it somehow an older, more austere look. The shadowy half light had erased the boyishness from his countenance, replacing it with a suggestion of somberness.
"Why did you come into the hills?" he demanded abruptly.
Brent did not immediately answer; he chewed on, toying with an idea. He was in as desperate a plight as he could be in, and he saw no way out. He looked about, seeing that his captors were out of earshot. He did not see the dim shape that squirmed up behind the boulder against which he leaned. He reached a sudden decision and spoke.
"Do you know the man called El Borak?"
Was there suspicion suddenly in the black eyes?
"I have heard of him," Shirkuh replied warily:
"I came into the hills looking for him. Can you find him? If you could get a message to him, I would pay you thirty thousand rupees."
Shirkuh scowled, as if torn between suspicion and avarice.
"I am a stranger in these hills," he said. "How could I find El Borak?"
"Then help me to escape," urged Brent. "I will pay you an equal sum."
Shirkuh tugged his mustache.
"I am one sword against thirty," he growled. "How do I know I would be paid? Feringi are all liars. I am an outlaw with a price on my head. The Turks would flay me, the Russians would shoot me, the British would hang me. There is nowhere I can go except to Rub el Harami. If I helped you to escape, that door would be barred against me, too."
"I will speak to the British for you," urged Brent. "El Borak has power. He will secure a pardon for you."
He believed what he said; besides, he was in that desperate state when a man is likely to promise anything.
Indecision flickered in the black eyes, and Shirkuh started to speak, then changed his mind, turned on his heel, and strode away. A moment later the spy crouching behind the boulders glided away without having been discovered by Brent, who sat staring in despair after Shirkuh.
Shirkuh went straight to Muhammad, gnawing strips of dried mutton as he sat cross-legged on a dingy sheepskin near a small fire on the other side of the well. Shirkuh got there before the spy did.
"The Feringi has offered me money to take a word to El Borak," he said abruptly. "Also to aid him to escape. I bade him go to Jehannum, of course. In the Jebel Jawur I have heard of El Borak, but I have never seen him. Who is he?"
"A devil," growled Muhammad ez Zahir. "An American, like this dog. The tribes about the Khyber are his friends, and he is an adviser of the ameer, and an ally of the rajah, though he was once an outlaw. He has never dared come to Rub el Harami. I saw him once, three years ago, in the fight by Kalat-i-Ghilzai, where he and his cursed Afridis broke the back of the revolt that had else unseated the ameer. If we could catch him, Abd el Khafid would fill our mouths with gold."
"Perhaps this Feringi knows where to find him!" exclaimed Shirkuh, his eyes burning with a glitter that might have been avarice. "I will go to him and swear to deliver his message, and so trick him into telling me what he knows of El Borak."
"It is all one to me," answered Muhammad indifferently. "If I had wished to know why he came into the hills, I would have tortured it out of him before now. But my orders were merely to capture him and bring him alive to Rub el Harami. I could not turn aside, not even to capture El Borak. But if you are admitted into the city, perhaps Abd el Khafid will give you a troop to go hunting El Borak."
"I will try!"
"Allah grant you luck," said Muhammad. "El Borak is a dog. I would myself give a thousand rupees to see him hanging in the market place."
"If it be the will of Allah, you shall meet El Borak!" said Shirkuh, turning away.
Doubtless it was the play of the firelight on his face which caused his eyes to burn as they did, but Muhammad felt a curious chill play down his spine, though he could not reason why.
Shirkuh's booted feet crunched away through the shale, and a furtive, ragged shadow came out of the night and squatted at Muhammad's elbow.
"I spied on the Kurd and the infidel as you ordered," muttered the spy. "The Feringi offered Shirkuh thirty thousand rupees either to seek out El Borak and deliver a message to him, or to aid him to escape us. Shirkuh lusted for the gold, but he has been outlawed by all the Feringis, and he dares not close the one door open to him."
"Good," growled Muhammad in his beard. "Kurds are dogs; it is well that this one is in no position to bite. I will speak for him at the pass. He does not guess the choice that awaits him at the gates of Rub el Harami."
Brent was sunk in the dreamless slumber of exhaustion, despite the hardness of the rocky ground and the chill of the night. An urgent hand shook him awake, an urgent whisper checked his startled exclamation. He saw a vague shape bending over him, and heard the snoring of his guard a few feet away. Guarding a man bound and fettered was more or less of a formality of routine. Shirkuh's voice hissed in Brent's ear.
"Tell me the message you wished to send El Borak! Be swift, before the guard awakes. I could not take the message when we talked before, for there was a cursed spy listening behind that rock. I told Muhammad what passed between us, because I knew the spy would tell him anyway, and I wished to disarm suspicion before it took root. Tell me the word!"
Brent accepted the desperate gamble.
"Tell him that Richard Stockton died, but before he died, he said this: "The Black Tigers have a new prince; they call him Abd el Khafid, but his real name is Vladimir Jakrovitch." This man dwells in Rub el Harami, Stockton told me."
"I understand," muttered Shirkuh. "El Borak shall know."
"But what of me?" urged Brent.
"I cannot help you escape now," muttered Shirkuh. "There are too many of them. All the guards are not asleep. Armed men patrol the outskirts of the camp, and others watch the horses--my own among them."
"I cannot pay you unless I get away!" argued Brent.
"That is in the lap of Allah!" hissed Shirkuh. "I must slip back to my blankets now, before I am missed. Here is a cloak against the chill of the night."
Brent felt himself enveloped in a grateful warmth, and then Shirkuh was gone, gliding away in the night with boots that made no more noise than the moccasins of a red Indian. Brent lay wondering if he had done the right thing. There was no reason why he should trust Shirkuh. But if he had done no good, at least he could not see that he had done any harm, either to himself, El Borak, or those interests menaced by the mysterious Black Tigers. He was a drowning man, clutching at straws. At last he went to sleep again, lulled by the delicious warmth of the cloak Shirkuh had thrown over him, and hoping that he would slip away in the night and ride to find Gordon-wherever he might be wandering.
