The whistle came again, and again, in spite of her relentless spurring, her horse checked his pace. A sudden inspiration came to her. Perhaps it was the horse she was riding that was the cause of all the trouble. It was certainly the Arab's whistle that had made it moderate its speed; it was responding clearly to a signal that it knew. Her guide's reluctance to give any particulars of his acquisition of the horse came back to her. There could not be much doubt about it. The animal had unquestionably been stolen, and either belonged to or was known to the party of Arabs who had met them.
The naivete that paraded a stolen horse through the desert at the risk of meeting its former owner made her smile in spite of her annoyance, but it was not a pleasant smile, as her thoughts turned from the horse to its present owner. The sum of Mustafa Ali's delinquencies was mounting up fast. But it was his affair, not hers. In the meantime she had paid for the horse to ride through the desert, not to be waylaid by Arab bandits. Her temper was going fast.
She urged the horse on with all her power, but perceptibly he was slowing up. She flashed another backward look. The Arab was close behind her—closer than she had been aware. She had a momentary glimpse of a big white figure, dark piercing eyes, and white gleaming teeth, and passionate rage filled her. With no thought of what the consequences or retaliation might be, with no thought at all beyond a wild desire to rid herself of her pursuer, driven by a sudden madness which seemed to rise up in her and which she could not control, she clutched her revolver and fired twice, full in the face of the man who was following her. He did not even flinch and a low laugh of amusement came from him. And at the sound of his laugh Diana's mouth parched suddenly, and a cold shiver rippled across her spine. A strange feeling that she had never experienced before went through her. She had missed again as she had missed this morning. How, she did not know; it was inexplicable, but it was a fact, and a fact that left her with a feeling of powerlessness. She dropped the useless revolver, trying vainly to force her horse's pace, but inch by inch the fiery chestnut that the Arab was riding crept up nearer alongside. She would not turn to look again, but glancing sideways she could see its small, wicked-looking head, with flat laid ears and vicious, bloodshot eyes, level with her elbow. For a moment or two it remained there, then with a sudden spurt the chestnut forged ahead, and as it shot past it swerved close in beside her, and the man, rising in his stirrups and leaning towards her, flung a pair of powerful arms around her, and, with a jerk, swung her clear of the saddle and on to his own horse in front of him. His movement had been so quick she was unprepared and unable to resist. For a moment she was stunned, then her senses came back to her and she struggled wildly, but, stifled in the thick folds of the Arab's robes, against which her face was crushed, and held in a grip that seemed to be slowly suffocating her, her struggles were futile. The hard, muscular arm round her hurt her acutely, her ribs seemed to be almost breaking under its weight and strength, it was nearly impossible to breathe with the close contact of his body. She was unusually strong for a girl, but against this steely strength that held her she was helpless. And for a time the sense of her helplessness and the pain that any resistance to the arm wrapped round her gave her made her lie quiet. She felt the Arab check his horse, felt the chestnut wheel, spinning high on his hind legs, and then bound forward again.
Her feelings were indescribable. She did not know what to think. Her mind felt jarred. She was unable to frame any thoughts coherently. What had happened was so unexpected, so preposterous, that no conclusion seemed adequate. Only rage filled her—blind, passionate rage against the man who had dared to touch her, who had dared to lay his hands on her, and those hands the hands of a native. A shiver of revulsion ran through her. She was choking with fury, with anger and with disgust. The ignominy of her plight hurt her pride badly. She had been outridden, swept from her saddle as if she were a puppet, and compelled to bear the proximity of the man's own hateful body and the restraint of his arms. No one had ever dared to touch her before. No one had ever dared to handle her as she was being handled now. How was it going to end? Where were they going? With her face hidden she had lost all sense of direction. She had no idea to what point the horse had turned when he had wheeled so suddenly. He was galloping swiftly with continual disconcerting bounds that indicated either temper or nerves, but the man riding him seemed in no way disturbed by his horse's behavior. She could feel him swaying easily in the saddle, and even the wildest leaps did not cause any slackening of the arm around her.
But by degrees as she continued to lie still the pressure on her body was relieved slightly, and she was able to turn her head a little towards the air for which she was almost fainting, but not enough to enable her to see what was passing around her. She drank in the cool air eagerly. Though she could not see she knew that the night had come, the night that she had hoped would fall before she reached her destination, but which now seemed horrible. The fresh strength that the air gave her fanned the courage that still remained with her. Collecting all her force she made a sudden desperate spring, trying to leap clear of the arm that now lay almost loosely about her, her spurred heels tearing the chestnut's flank until he reared perpendicularly, snorting and trembling. But with a quick sweep of his long arm the Arab gathered her back into his hold, still struggling fiercely. His arms were both round her; he was controlling the maddened horse only with the pressure of his knees.
"Doucement, doucement." She heard the slow, soft voice indistinctly, for he was pressing her head again closely to him, and she did not know if the words were applied to herself or to the horse. She fought to lift her head, to escape the grip that held her, straining, striving until he spoke again.
"Lie still, you little fool!" he snarled with sudden vehemence, and with brutal hands he forced her to obey him, until she wondered if he would leave a single bone unbroken in her body, till further resistance was impossible. Gasping for breath she yielded to the strength that overpowered her, and ceased to struggle. The man seemed to know intuitively that she was beaten, and turned his undivided attention to his horse with the same low laugh of amusement that had sent the strange feeling through her when her shots had missed him. It had puzzled her then, but it grew now with a horrible intensity, until she knew that it was fear that had come to her for the first time in her life—a strange fear that she fought against desperately, but which was gaining on her with a force that was sapping her strength from her and making her head reel. She did not faint, but her whole body seemed to grow nerveless with the sudden realisation of the horror of her position.
