"What are you going to do?" asked Craven with a backward glance at the dismounted tribesmen clustering round the well and busily employed in making preparations for rest and food. Saïd beckoned to a passing Arab and dispatched him with a hurried order. Then he turned again to Craven. "The horses must rest though the men would go forward at a word. I am sending two scouts to reconnoitre the defile and bring back what information they can," he said. And as he spoke the two men he had sent for appeared with disciplined promptness and reined in beside him. Having received their brief instructions they started off in a cloud of dust and sand at the usual headlong gallop. Saïd turned away immediately and disappeared among the jostling crowd, but Craven lingered at the edge of the oasis looking after the fast receding horsemen who, crouched low in their saddles, their long white cloaks swelling round them, were very literally carrying out their orders to ride "swift as the messengers of Azrael." He had known them both on his previous visits, though he had not recognised them in the dark hours of the dawn when they joined the troop, and remembered them as two of the most dare-devil and intrepid of Mukair Ibn Zarrarah's followers. A moment since they had grinned at him in cheery greeting, exhibiting almost childlike pleasure when he had called them by name, and had set off with an obeisance as deep to him as to their leader.
Incidents of those earlier visits flashed through his mind as he watched them speeding across the glaring plain and a feeling almost of regret came to him that it should be these two particular men who had been selected for the hazardous mission. For he guessed that their chance of return was slight. And yet hardly slighter than for the rest of them! With a shrug he moved away slowly and sought the shadow of a camel thorn. He lay on his back in the welcome patch of shade, his helmet tilted over his eyes, drawing vigorously at a cigarette in the vain hope of lessening the attentions of the swarms of tormenting flies that buzzed about him, and waiting patiently for the desired water before he swallowed the dark brown unsavoury mass of crushed dates which, warm from his pocket and gritty with the sand that penetrated everything, was the only food available. Saïd was still busy among the throng of men and horses, but near him Omar sat plunged in gloomy silence, his melancholy eyes fixed on the distant hills. He had re-adjusted his robes, screening the ominous stain that revealed what he wished to hide. His hands, which alone might have betrayed the emotion surging under his outward passivity, were concealed in the folds of his enveloping burnous. When the immediate wants of men and horses were assuaged the prevailing clamour gave place to sudden quiet as the Arabs lay down and, muffling their heads in their cloaks, seemed to fall instantly asleep. His supervision ended, Saïd reappeared, and following the example of his men was soon snoring peacefully. Craven rolled over on his side, and lighting another cigarette settled himself more comfortably on the warm ground. For a time he watched the solitary sentinel sitting motionless on his horse at no great distance from the oasis. Then a vulture winging its slow heavy way across the heavens claimed his attention and he followed it with his eyes until it passed beyond his vision. He was too lazy and too comfortable to turn his head. He lay listening to the shrill hum of countless insect life, smoking cigarette after cigarette till the ground around him was littered with stubs and match ends. The hours passed slowly. When he looked at the guard again the Arab was varying the monotony by walking his horse to and fro, but he had not moved further into the desert. And suddenly as Craven watched him he wheeled and galloped back toward the camp. Craven started up on his arm, screening his eyes from the sun and staring intently in the direction of the hills. But there was nothing to be seen in the wide empty plain, and he sank down again with a smile at his own impatience as the reason of the man's return occurred to him. Reaching the oasis the Arab led his horse among the prostrate sleepers and kicked a comrade into wakefulness to take his place. From time to time the intense stillness was broken by a movement among the horses, and once or twice a vicious scream came from a stallion resenting the attentions of a restless neighbour. The slumbering Arabs lay like sheeted figures of the dead save when some uneasy dreamer rolled over with a smothered grunt into a different position. Craven had begun to wonder how much longer the siesta would be protracted when Omar rose stiffly, and going to his brother's side awoke him with a hand on his shoulder. Saïd sat up blinking sleepily and then leaped alertly to his feet. In a few minutes the oasis was once more filled with noisy activity. But this time there was no confusion. The men mounted quickly and the troop was reformed with the utmost dispatch. The horses broke almost immediately into the long swinging gallop that seemed to eat up the miles under their feet.
