"It is well said, Aga. I will give the camels a handful of beans which they will chew peacefully, and so refrain from disturbing the night with their roaring; then we will make a circuit and come to the ruins even as the sun sets."
Less than half an hour later the two men, having made their way back to the ruins, crept stealthily to the southern corner, where they could see the spot on which the five men had camped. It was growing dark, but in the slight glow from the western sky they perceived at once that the men were no longer there. There was no sign of them in what was visible of the open desert to the west; it was indeed scarcely likely that they had decided to pursue their journey on horses so patently fatigued. Ibrahim suggested in a whisper that they had withdrawn farther into the ruins to avoid observation by passengers along the direct route from Kerbela to Meshed Ali.
This was disappointing. The ruins were extensive; to explore them in the dark would be as hazardous as difficult. Their footsteps would be inaudible in the sand; but they might stumble against one of the innumerable fragments of masonry that lay scattered all about, and the Arab's ears are so quick that the slightest sound might utterly defeat their purpose. The night would be moonless; even if it had been otherwise, moonlight would have been little less dangerous than darkness, for though they could have seen their way, a flickering shadow might have betrayed them.
In whispers they discussed their safest course. Burnet agreed to remain on the outskirts of the ruins while Ibrahim searched. When the Arab started on his quest darkness had descended, and there was only a slight glimmer from the stars. It seemed hours before he returned. He explained that he had almost despaired of finding the men, and concluded that they had after all ridden away to the north, when he suddenly heard voices, and creeping towards the sound had almost stumbled upon the party, encamped in the midst of a group of broken columns hidden by a slight fold in the ground. Their horses were tethered some little distance away, and from the appearance of things it seemed clear that the men had no intention of leaving the spot until daybreak.
During Ibrahim's absence Burnet had turned over in his mind, not merely the problem of getting the dervish away, but the further problem of successfully eluding pursuit. Tired as the horses were, they had probably had rest enough to make them more than equal to the camels in pace. Should he stampede them? It would be easy enough, but the attempt might lead to disaster, for they would almost certainly scent a stranger long before he reached them, and a startled whinny would bring the Arabs in haste upon the scene. The safer plan would be to depend on releasing the prisoner while his captors were asleep, and then on following a roundabout course through the desert.
The two men consulted in whispers and soon came to a determination. Burnet, as the more active of the two, and also as being well known to the prisoner, undertook the task of releasing him. Ibrahim meanwhile would ensconce himself at a convenient spot near at hand, and remain on the watch, ready to defend the others with his rifle if need arose.
The Arab has an almost unerring sense of locality and direction, and in spite of the darkness Ibrahim was able to lead Burnet without fault through the maze of ruins to the slight hollow where the men were encamped. Looking down upon it from his higher point a few yards away, Burnet was just able to discern, by the glimmer of the stars, five figures on the ground. Four of them were squatting; every now and then a word was spoken; the fifth lay at full stretch, a little apart from the others.
Burnet watched and listened impatiently. Surely the men would not remain thus the whole night through. What if they slept in turn, leaving one always on guard? After a while the conversation became still more spasmodic and drowsy: presently it ceased altogether, and all four men sank into a recumbent posture. Secure in their retreat far within the ruins, they had seen no need of keeping guard.
All was now silent. Not even a snore broke the stillness. Only a slight clink came occasionally from the spot where the horses were tethered. Burnet still waited, though he knew that the Arab, like all creatures of the wild, falls asleep instantly. But he knew also that the sleep was light. The least unusual sound, inaudible to a European ear, would cause these men to spring up, as wide awake and alert as a house-dog.
At last he moved, stealing along a few feet away from the rim of the hollow until he came opposite the spot where the fifth man lay. Then, after a momentary pause, he wriggled down the slope as noiselessly as a slug, breathing fast, drawing nearer only inch by inch to his friend. He touched him lightly; the prisoner started, but relapsed immediately into immobility. Feeling along the inert body, Burnet discovered that now both hands and feet were bound. With silent cuts of his knife he severed the cords, lay for a moment listening, then crawled backwards up the slope. Why was not the prisoner following him? He had gained the top before the dervish gave any sign of movement. Then, however, he began slowly to follow, and Burnet guessed that his limbs were stiff from his bonds. Watching with eager impatience, he saw the greyish figure, scarcely distinguishable from the earth, draw nearer to the top. The Arabs slept on undisturbed. And at last the dervish rose to his feet, clasped Burnet's hand, and followed him silently to the spot where Ibrahim was awaiting them. Without a word spoken they hastened with all speed to the camels. The dervish mounted behind Burnet, and within twenty minutes of his rescue all three were heading southwards. At the moment of starting they had a slight alarm. Ibrahim's camel, annoyed, no doubt, at the early disturbance of his rest, uttered a hoarse grunt. His master instantly pressed a couple of dates into his mouth, and the beast was appeased.
