her furious. Her guide was wounded, his men surrounded, and she was ignominiously being run away with by a bolting horse. If she could only turn the wretched animal. It would only be a question of ransom, of that she was positive. She must get back somehow to the others and arrange terms. It was an annoyance, of course, but after all it added a certain piquancy to her trip, it would be an experience. It was only a "hold-up." She did not suppose the Arabs had even really meant to hurt any one, but they were excited and some one's shot, aimed wide, had found an unexpected billet. It could only be that. It was too near Biskra for any real danger, she argued with herself, still straining on the reins. She would not admit that there was any danger, though her heart was beating in a way that it had never done before. Then as she hauled ineffectually at the bridle with all her strength there came from behind her the sound of a long, shrill whistle. Her horse pricked up his ears and she was conscious that his pace sensibly lessened. Instinctively she looked behind. A solitary Arab was riding after her and as she looked she realised that his horse was gaining on hers. The thought drove every idea of stopping her runaway from her and made her dig her spurs into him instead. There was a sinister air of deliberation in the way in which the Arab was following her; he was riding her down.
Diana's mouth closed firmly and a new keenness came into her steady eyes. It was one thing to go back voluntarily to make terms with the men who had attacked her party; it was quite another thing to be deliberately chased across the desert by an Arab freebooter. Her obstinate chin was almost square. Then the shadow of a laugh flickered in her eyes and curved her mouth. New experiences were crowding in upon her to-day. She had often wondered what the feelings of a hunted creature were. She seemed in a fair way of finding out. She had always stoutly maintained that the fox enjoyed the run as much as the hounds; that remained to be proved, but, in any case, she would give this hound a run for his money. She could ride, and there seemed plenty yet in the frightened animal under her. She bent down, lying low against his neck with a little, reckless laugh, coaxing him with all her knowledge and spurring him alternately. But soon her mood changed. She frowned anxiously as she looked at the last rays of the setting sun. It would be dark very soon. She could not go chasing through the night with this tiresome Arab at her heels. The humour seemed to have died out of the situation and Diana began to get angry. In the level country that surrounded her there were no natural features that could afford cover or aid in any way; there seemed nothing for it but to own herself defeated and pull up—if she could. An idea of trying to dodge him and of returning of her own free will was dismissed at once as hopeless. She had seen enough in her short glimpse of the Arabs' tactics when they had passed her to know that she was dealing with a finished horseman on a perfectly trained horse, and that her idea could never succeed. But, perversely, she felt that to that particular Arab following her she would never give in. She would ride till she dropped, or the horse did, before that.
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
