"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. After that Diana lost all sense of time, as she had already lost all sense of direction. She did not know if it was minutes or hours that passed as they still galloped swiftly through the night. She did not know if they were alone or if the band of Arabs to which this man belonged were riding with them, noiseless over the soft ground. What had happened to her guide and his men? Had they been butchered and left where they fell, or were they, too, being hurried unwillingly into some obscure region of the desert? But for the moment the fate of Mustafa Ali and his companions did not trouble her very much; they had not played a very valiant part in the short encounter, and her own situation swamped her mind to the exclusion of everything else. The sense of fear was growing on her. She scorned and derided it. She tried to convince herself it did not exist, but it did exist, torturing her with its strangeness and with the thoughts that it engendered. She had anticipated nothing like this. She had never thought of a contingency that would end so, that would induce a situation before which her courage was shuddering into pieces with the horror that was opening up before her--a thing that had always seemed a remote impossibility that could never touch her, from even the knowledge of which her life with Aubrey had almost shielded her, but which now loomed near her, forcing its reality upon her till she trembled and great drops of moisture gathered on her forehead.
