Far to the east a low blue line lay on the horizon. It was the range of hills that held the caves of El Khour. He was still ahead of Hawkston, forging on somewhere far to the south. But the Englishman would be gaining on him at every stride. Gordon could swing wide to avoid the men at the Well, and trudge on. Trudge on, afoot, and with empty water-bag? It would be suicide. He could never reach the caves on foot and without water. Already he was bitten by the devils of thirst.

  A red flame grew up in his eyes, and his dark face set in wolfish lines. Water was life in the desert; life for him and for Al Wazir. There was water at the Well, and camels. There were men, his enemies, in possession of both. If they lived, he must die. It was the law of the wolf-pack, and of the desert. He slipped the limp bags from his shoulders, cocked his rifle and went forward to kill or be killed--not for wealth, nor the love of a woman, nor an ideal, nor a dream, but for as much water as could be carried in a sheep-skin bag.

  A wadi or gully broke the plain ahead of him, meandering to a point within a few hundred feet of the Well. Gordon crept toward it, taking advantage of every bit of cover. He had almost reached it, at a point a hundred yards from the Well, when a man in white kafieh and ragged abba materialized from among the palms. Discovery in the growing light was instant. The Arab yelled and fired. The bullet knocked up dust a foot from Gordon’s knee, as he crouched on the edge of the gully, and he fired back. The Arab cried out, dropped his rifle and staggered drunkenly back among the palms.

  The next instant Gordon had sprung down into the gully and was moving swiftly and carefully along it, toward the point where it bent nearest the Well. He glimpsed white-clad figures flitting briefly among the trees, and then rifles began to crack viciously. Bullets sang over the gully as the men fired from behind their saddles and bales of goods, piled like a rampart among the stems of the palms. They lay in the eastern fringe of the clump; the camels, Gordon knew, were on the other side of the trees. From the volume of the firing it could not be a large party.

  A rock on the edge of the gully provided cover. Gordon thrust his rifle barrel under a jutting corner of it and watched for movement among the palms. Fire spurted and a bullet whined off the rock--zingggg! Dwindling in the distance like the dry whir of a rattler. Gordon fired at the puff of smoke, and a defiant yell answered him.

  His eyes were slits of black flame. A fight like this could last for days. And he could not endure a siege. He had no water; he had no time. A long march to the south the caravan of Hawkston was swinging relentlessly westward, each step carrying them nearer the caves of El Khour and the unsuspecting man who dreamed his dreams there. A few hundred feet away from Gordon there was water, and camels that would carry him swiftly to his destination; but lead-fanged wolves of the desert lay between.

  Lead came at his retreat thick and fast, and vehement voices rained maledictions on him. They let him know they knew he was alone, and on foot, and probably half-mad with thirst. They howled jeers and threats. But they did not expose themselves. They were confident but wary, with the caution taught by the desert deep ingrained in them. They held the winning hand and they intended to keep it so.

  An hour of this, and the sun climbing over the eastern rim, and the heat beginning--the molten, blinding heat of the southern desert. It was fierce already; later it would be a scorching hell in that unshielded gully. Gordon licked his blackened lips and staked his life and the life of Al Wazir on one desperate cast of Fate’s blind dice.

  Recognizing and accepting the terrible odds against success, he raised himself high enough to expose head and one shoulder above the gully rim, firing as he did so. Three rifles cracked together and lead hummed about his ears; the bullet of one raked a white-hot line across his upper arm. Instantly Gordon cried out, the loud, agonized cry of a man hard hit, and threw his arms above the rim of the gully in the convulsive gesture of a man suddenly death-stricken. One hand held the rifle and the motion threw it out of the gully, to fall ten feet away, in plain sight of the Arabs.

  An instant’s silence, in which Gordon crouched below the rim, then blood-thirsty yells echoed his cry. He dared not raise himself high enough to look, but he heard the slap-slap-slap of sandalled feet, winged by hate and blood-lust. They had fallen for his ruse. Why not? A crafty man might feign a wound and fall, but who would deliberately cast away his rifle? The thought of a Feringhi, lying helpless and badly wounded in the bottom of the gully, with a defenseless throat ready for the knife, was too much for the blood-lust of the Bedouins. Gordon held himself in iron control, until the swift feet were only a matter of yards away--then he came erect like a steel spring released, the big automatic in his hand.

  As he leaped up he caught one split-second glimpse of three Arabs, halting dead in their tracks, wild-eyed at the unexpected apparition--even as he straightened-his gun was roaring. One man spun on his heel and fell in a crumpled heap, shot through the head. Another fired once, with a rifle, from the hip, without aim. An instant later he was down, with a slug through his groin and another ripping through his breast as he fell. And then Fate took a hand again--Fate in the form of a grain of sand in the mechanism of Gordon’s automatic. The gun jammed just as he threw it down on the remaining Arab.

  This man had no gun; only a long knife. With a howl he wheeled and legged it back for the grove, his rags whipping on the wind of his haste. And Gordon was after him like a starving wolf. His strategy might go for nothing if the man got back among the trees, where he might have left a rifle.

  The Bedouin ran like an antelope, but Gordon was so close behind him when they reached the trees, the Arab had no time to snatch up the rifle leaning against the improvised rampart. He wheeled at bay, yowling like a mad dog, and slashing with the long knife. The point tore Gordon’s shirt as the American dodged, and brought down the heavy pistol on the Arab’s head. The thick kafieh saved the man’s skull from being crushed, but his knees buckled and he went down, throwing his arms about Gordon’s waist and dragging down the white man as he fell. Somewhere on the other side of the grove the wounded man was calling down curses on El Borak.

  The two men rolled on the ground, ripping and smiting like wild animals. Gordon struck once again with his gun barrel, a glancing blow that laid open the Arab’s face from eye to jaw, and then dropped the jammed pistol and caught at the arm that wielded the knife. He got a grip with his left hand on the wrist and the guard of the knife itself, and with his other hand began to fight for a throat-hold. The Arab’s ghastly, blood-smeared countenance writhed in a tortured grin of muscular strain. He knew the terrible strength that lurked in El Borak’s iron fingers, knew that if they closed on his throat they would not let go until his jugular was torn out.

  He threw his body frantically from side to side, wrenching and tearing. The violence of his efforts sent both men rolling over and over, to crash against palm stems and carom against saddles and bales. Once Gordon’s head was driven hard against a tree, but the blow did not weaken him, nor did the vicious drive the Arab got in with a knee to his groin. The Bedouin grew frantic, maddened by the fingers that sought his throat, the dark face, inexorable as iron, that glared into his own. Somewhere on the other side of the grove a pistol was barking, but Gordon did not feel the tear of lead, nor hear the whistle of bullets.

  With a shriek like a wounded panther’s, the Arab whirled over again, a knot of straining muscles, and his hand, thrown out to balance himself, fell on the barrel of the pistol Gordon had dropped. Quick as a flash he lifted it, just as Gordon found the hold he had been seeking, and crashed the butt down on the American’s head with every ounce of strength in his lean sinews, backed by the fear of death. A tremor ran through the American’s iron frame, and his head fell forward. And in that instant the Ruweila tore free like a wolf breaking from a trap, leaving his long knife in Gordon’s hand.

  Even before Gordon’s brain cleared, his war-trained muscles were responding instinctively. As the Ruweila sprang up, he shook his head and rose more slowly, the long knife in
his hand. The Arab hurled the pistol at him, and caught up the rifle which leaned against the barrier. He gripped it by the barrel with both hands and wheeled, whirling the stock above his head; but before the blow could fall Gordon struck with all the blinding speed that had earned him his name among the tribes. In under the descending butt he lunged and his knife, driven with all his strength and the momentum of his charge, plunged into the Arab’s breast and drove him back against a tree into which the blade sank a hand’s breadth deep. The Bedouin cried out, a thick, choking cry that death cut short. An instant he sagged against the haft, dead on his feet and nailed upright to the palm tree. Then his knees buckled and his weight tore the knife from the wood and he pitched into the sand.

  Gordon wheeled, shaking the sweat from his eyes, glaring about for the fourth man--the wounded man. The furious fight had taken only a matter of moments. The pistol was still cracking dryly on the other side of the trees, and an animal scream of pain mingled with the reports.

  With a curse Gordon caught up the Arab’s rifle and burst through the grove. The wounded man lay under the shade of the trees, propped on an elbow, and aiming his pistol, not at El Borak but at the one camel that still lived. The other three lay stretched in their blood. Gordon sprang at the man, swinging the rifle stock. He was a split-second too late. The shot cracked and the camel moaned and crumpled even as the butt fell on the lifted arm, snapping the bone like a twig. The smoking pistol fell into the sand and the Arab sank back, laughing like a ghoul.

  “Now see if you can escape from the Well of Amir Khan, El Borak!” he gasped. “The riders of Shalan ibn Mansour are out! Tonight or tomorrow they will return to the Well! Will you await them here, or flee on foot to die in the desert, or be tracked down like a wolf? Ya kalb! Forgotten of God! They will hang thy skin on a palmtree! Laan abuk--!”

  Lifting himself with an effort that spattered his beard with bloody foam, he spat toward Gordon, laughed croakingly and fell back, dead before his head hit the ground.

  Gordon stood like a statue, staring down at the dying camels. The dead man’s vengeance was grimly characteristic of his race. Gordon lifted his head and looked long at the low blue range on the western horizon. Cheeringly the dying Arab had foretold the grim choice left him. He could wait at the Well until Shalan ibn Mansour’s wild riders returned and wiped him out by force of numbers, or he could plunge into the desert again on foot. And whether he awaited certain doom at the Well, or sought the uncertain doom of the desert, inexorably Hawkston would be marching westward, steadily cutting down the lead Gordon had had at the beginning.

  But Gordon never had any doubt concerning his next move. He drank deep at the Well, and bolted some of the food the Arabs had been preparing for their breakfast. Some dried dates and crusted cheese-balls he placed in a food-bag, and he filled a water-skin from the Well. He retrieved his rifle, got the sand out of his automatic and buckled to his belt a scimitar from the girdle of one of the men he had killed. He had come into the desert intending to run and hide, not to fight. But it looked very much as if he would do much more fighting before this venture was over, and the added weight of the sword was more than balanced by the feeling of added security in the touch of the lean curved blade.

  Then he slung the water-skin and food-bag over his shoulders, took up his rifle and strode out of the shadows of the grove into the molten heat of the desert day. He had not slept at all the night before. His short rest at the Well had put new life and spring into his resilient muscles, hardened and toughened by an incredibly strenuous life. But it was a long, long march to the caves of El Khour, under a searing sun. Unless some miracle occurred, he could not hope to reach them before Hawkston now. And before another sun-rise the riders of Shalan ibn Mansour might well be on his trail, in which case--but all he had ever asked of Fortune was a fighting chance.

  The sun rocked its slow, torturing way up the sky and down; twilight deepened into dusk, and the desert stars winked out; and on, grimly on, plodded that solitary figure, pitting an indomitable will against the merciless immensity of thirst-haunted desolation.

  CHAPTER 4

  The caves of El Khour pit the sheer eastern walls of a gaunt hill-range that rises like a stony backbone out of a waste of rocky plains. There is only one spring in the hills; it rises in a cave high up in the wall and curls down the steep rocky slope, a slender thread of silver, to empty into a broad shallow pool below. The sun was hanging like a blood-red ball above the western desert when Francis Xavier Gordon halted near this pool and scanned the rows of gaping cave-mouths with blood-shot eyes. He licked heat-blackened lips with a tongue from which all moisture had been baked. Yet there was still a little water in the skin on his shoulder. He had economized on that gruelling march, with the savage economy of the wilderness-bred.

  It seemed a bit hard to realize he had actually reached his goal. The hills of El Khour had shimmered before him for so many miles, unreal in the heat-waves, until at last they had seemed like a mirage, a fantasy of a thirst-maddened imagination. The desert sun plays tricks even with a brain like Gordon’s. Slowly, slowly the hills had grown up before him--now he stood at the foot of the eastern-most cliff, frowning up at the tiers of caves which showed their black mouths in even rows.

  Nightfall had not brought Shalan ibn Mansour’s riders swooping after the solitary wanderer, nor had dawn brought them. Again and again through the long, hot day, Gordon had halted on some rise and looked back, expecting to see the dust of the hurrying camels; but the desert had stretched empty to the horizon.

  And now it seemed another miracle had taken place, for there were no signs of Hawkston and his caravan. Had they come and gone? They would have at least watered their camels at the pool; and from the utter lack of signs about it, Gordon knew that no one had camped or watered animals at the pool for many moons. No, it was indisputable, even if unexplainable. Something had delayed Hawkston and Gordon had reached the caves ahead of him after all.

  The American dropped on his belly at the pool and sank his face into the cool water. He lifted his head presently, shook it like a lion shaking his mane, and leisurely washed the dust from his face and hands.

  Then he rose and went toward the cliff. He had seen no sign of life, yet he knew that in one of those caves lived the man he had come to seek. He lifted his voice in a far-carrying shout.

  “Al Wazir! Ho there, Al Wazir!”

  “Wazirrr!” whispered the echo back from the cliff. There was no other answer. The silence was ominous. With his rifle at the ready Gordon went toward the narrow trail that wound up the rugged face of the cliff. Up this he climbed, keenly scanning the eaves. They pitted the whole wall, in even tiers--too even to be the chance work of nature. They were man-made. Thousands of years ago, in the dim dawn of pre-history they had served as dwelling-places for some race of people who were not mere savages, who nitched their caverns in the soft strata with skill and cunning. Gordon knew the caves were connected by narrow passages, and that only by this ladder-like path he was following could they be reached from below.

  The path ended at a long ledge, upon which all the caves of the lower tier opened. In the largest of these Al Wazir had taken up his abode.

  Gordon called again, without result. He strode into the cave, and there he halted. It was square in shape. In the back wall and in each side wall showed a narrow door-like opening. Those at the sides led into adjoining caves. That at the back let into a smaller cavern, without any other outlet. There, Gordon remembered, Al Wazir had stored the dried and tinned foods he had brought with him. He had brought no furniture, nor weapons.

  In one corner of the square cave a heap of charred fragments indicated that a fire had once been built there. In one corner lay a heap of skins--Al Wazir’s bed. Nearby lay the one book Al Wazir had brought with him--The Bhagavat-Gita. But of the man himself there was no evidence.

  Gordon went into the storeroom, struck a match and looked about him. The tins of food were there, though the supply was considerably
depleted. But they were not stacked against the wall in neat columns as Gordon had seen them stowed under Al Wazir’s directions. They were tumbled and scattered about all over the floor, with open and empty tins among them. This was not like Al Wazir, who placed a high value on neatness and order, even in small things. The rope he had brought along to aid him in exploring the caves lay coiled in one corner.

  Gordon, extremely puzzled, returned to the square cave. Here, he had fully expected to find Al Wazir sitting in tranquil meditation, or out on the ledge meditating over the sun-set desert. Where was the man?

  He was certain that Al Wazir had not wandered away to perish in the desert. There was no reason for him to leave the caves. If he had simply tired of his lonely life and taken his departure, he would have taken the book that was lying on the floor, his inseparable companion. There was no blood-stain on the floor, or anything to indicate that the hermit had met a violent end. Nor did Gordon believe that any Arab, even the Ruweila, would molest the “holy man.” Anyway, if Arabs had done away with Al Wazir, they would have taken away the rope and the tins of food. And he was certain that, until Hawkston learned of it, no white man but himself had known of Al Wazir’s whereabouts.
