"Bismillah el rahman el rahhim!" quoth Achmet resignedly, lifting his hands in a gesture of benediction, as the camel and its rider faded into the night.
"He rides to death," muttered a bearded Arab.
"Were it another man I should agree," said Achmet. "But it is El Borak who rides. Yet Shalan ibn Mansour would give many horses for his head."
The sun was swinging low over the desert, a tawny stretch of rocky soil and sand as far as Gordon could see in every direction. The solitary rider was the only visible sign of life, but Gordon's vigilance was keen. Days and nights of hard riding lay behind him; he was coming into the Ruweila country, now, and every step he took increased his danger by that much. The Ruweila, whom he believed to be kin to the powerful Roualla of El Hamad, were true sons of Ishmael—hawks of the desert, whose hands were against every man not of their clan. To avoid their country the regular caravan road to the west swung wide to the south. This was an easy route, with wells a day's march apart, and it passed within a day's ride of the Caves of El Khour, the catacombs which pit a low range of hills rising sheer out of the wastelands.
Few white men know of their existence, but evidently Hawkston knew of the ancient trail that turned northward from the Well of Khosru, on the caravan road. Hawkston was perforce approaching El Khour circuitously. Gordon was heading straight westward, across waterless wastes, cut by a trace so faint only an Arab or El Borak could have followed it. On that route there was but one watering place between the fringe of oases along the coast and the Caves —the half-mythical Well of Amir Khan, the existence of which was a secret jealously guarded by the Bedouins.
There was no fixed habitation at the oasis, which was but a clump of palms, watered by a small spring, but frequently bands of Ruweila camped there. That was a chance he must take. He hoped they were driving their camel herds somewhere far to the north, in the heart of their country; but like true hawks, they ranged far afield, striking at the caravans and the outlying villages.
The trail he was following was so slight that few would have recognized it as such. It stretched dimly away before him over a level expanse of stone- littered ground, broken on one hand by sand dunes, on the other by a succession of low ridges. He glanced at the sun, and tapped the water-bag that swung from the saddle. There was little left, though he had practiced the grim economy of a Bedouin or a wolf. But within a few hours he would be at the Well of Amir Khan, where he would replenish his supply—though his nerves tightened at the thought of what might be waiting there for him.
Even as the thought passed through his mind, the sun struck a glint from something on the nearer of the sand dunes. The quick duck of his head was instinctive, and simultaneously there rang out the crack of a rifle and he heard the thud of the bullet into flesh. The camel leaped convulsively and came down in a headlong sprawl, shot through the heart. Gordon leaped free as it fell, rifle in hand, and in an instant was crouching behind the carcass, watching the crest of the dune over the barrel of his rifle. A strident yell greeted the fall of the camel, and another shot set the echoes barking. The bullet ploughed into the ground beside Gordon's stiffening breastwork, and the American replied. Dust spurted into the air so near the muzzle that gleamed on the crest that it evoked a volley of lurid oaths in a choked voice.
The black glittering ring was withdrawn, and presently there rose the rapid drum of hoofs. Gordon saw a white kafieh bobbing among the dunes, and understood the Bedouin's plan. He believed there was only one man. That man intended to circle Gordon's position, cross the trail a few hundred yards west of him, and get on the rising ground behind the American, where his vantage- point would allow him to shoot over the bulk of the camel—for of course he knew Gordon would keep the dead beast between them. But Gordon shifted himself only enough to command the trail ahead of him, the open space the Arab must cross after leaving the dunes before he reached the protection of the ridges. Gordon rested his rifle across the stiff forelegs of the camel.
A quarter of a mile up the trail there was a sandstone rock jutting up in the skyline. Anyone crossing the trail between it and himself would be limned against it momentarily. He set his sights and drew a bead against that rock. He was betting that the Bedouin was alone, and that he would not withdraw to any great distance before making the dash across the trail.
Even as he meditated a white-clad figure burst from among the ridges and raced across the trail, bending low in the saddle and flogging his mount. It was a long shot, but Gordon's nerves did not quiver. At the exact instant that the white-clad figure was limned against the distant rock, the American pulled the trigger. For a fleeting moment he thought he had missed; then the rider straightened convulsively, threw up two wide-sleeved arms and reeled back drunkenly. The frightened horse reared high, throwing the man heavily. In an instant the landscape showed two separate shapes where there had been one —a bundle of white sprawling on the ground, and a horse racing off southward.
Gordon lay motionless for a few minutes, too wary to expose himself. He knew the man was dead; the fall alone would have killed him. But there was a slight chance that other riders might be lurking among the sand dunes, after all.
The sun beat down savagely; vultures appeared from nowhere—black dots in the sky, swinging in great circles, lower and lower. There was no hint of movement among the ridges or the dunes.
Gordon rose and glanced down at the dead camel. His jaws set a trifle more grimly; that was all. But he realized what the killing of his steed meant. He looked westward, where the heat waves shimmered. It would be a long walk, a long, dry walk, before it ended.
Stooping, he unslung water-skin and food-bag and threw them over his shoulders. Rifle in hand he went up the trail with a steady, swinging stride that would eat up the miles and carry him for hour after hour without faltering.
When he came to the shape sprawling in the path, he set the butt of his rifle on the ground and stood looking briefly, one hand steadying the bags on his shoulders. The man he had killed was a Ruweila, right enough: one of the tall, sinewy, hawk-faced and wolf-hearted plunderers of the southern desert. Gordon's bullet had caught him just below the arm-pit. That the man had been alone, and on a horse instead of a camel, meant that there was a larger party of his tribesmen somewhere in the vicinity. Gordon shrugged his shoulders, shifted the rifle to the crook of his arm, and moved on up the trail. The score between himself and the men of Shalan ibn Mansour was red enough, already. It might well be settled once and for all at the Well of Amir Khan.
As he swung along the trail he kept thinking of the man he was going to warn: Al Wazir, the Arabs called him, because of his former capacity with the Sultan of Oman. A Russian nobleman, in reality, wandering over the world in search of some mystical goal Gordon had never understood, just as an unquenchable thirst for adventure drove El Borak around the planet in constant wanderings. But the dreamy soul of the Slav coveted something more than material things. Al Wazir had been many things. Wealth, power, position; all had slipped through his unsatisfied fingers. He had delved deep in strange religions and philosophies, seeking the answer to the riddle of Existence, as Gordon sought the stimulation of hazard. The mysticisms of the Sufia had attracted him, and finally the ascetic mysteries of the Hindus.
A year before Al Wazir had been governor of Oman, next to the Sultan the wealthiest and most powerful man on the Pearl Coast. Without warning he had given up his position and disappeared. Only a chosen few knew that he had distributed his vast wealth among the poor, renounced all ambition and power, and gone like an ancient prophet to dwell in the desert, where, in the solitary meditation and self denial of a true ascetic, he hoped to read at last the eternal riddle of Life—as the ancient prophets read it. Gordon had accompanied him on that last journey, with the handful of faithful servants who knew their master's intentions—old Salim among them, for between the dreamy philosopher and the hard-bitten man of action there existed a powerful tie of friendship.
