The Arab moved her position once, roughly, but she was glad of the change for it freed her head from the stifling folds of his robes. He did not speak again--only once when the chestnut shied violently he muttered something under his breath. But her satisfaction was short-lived. A few minutes afterwards his arm tightened round her once more and he twined a fold of his long cloak round her head, blinding her. And then she understood. The galloping horse was pulled in with almost the same suddenness that had amazed her when she had first seen the Arabs. She felt him draw her close into his arms and slip down on to the ground; there were voices around her--confused, unintelligible; then they died away as she felt him carry her a few paces. He set her down and unwound the covering from her face. The light that shone around her seemed by contrast dazzling with the darkness that had gone before. Confused, she clasped her hands over her eyes for a moment and then looked up slowly. She was in a big, lofty tent, brightly lit by two hanging lamps. But she took no heed of her surroundings; her eyes were fixed on the man who had brought her there. He had flung aside the heavy cloak that enveloped him from head to foot and was standing before her, tall and broad-shouldered, dressed in white flowing robes, a waistcloth embroidered in black and silver wound several times about him, and from the top of which showed a revolver that was thrust into the folds. Diana's eyes passed over him slowly till they rested on his brown, clean-shaven face, surmounted by crisp, close-cut brown hair. It was the handsomest and cruellest face that she had ever seen. Her gaze was drawn instinctively to his. He was looking at her with fierce burning eyes that swept her until she felt that the boyish clothes that covered her slender limbs were stripped from her, leaving the beautiful white body bare under his passionate stare. She shrank back, quivering, dragging the lapels of her riding jacket together over her breast with clutching hands, obeying an impulse that she hardly understood. "Who are you?" she gasped hoarsely. "I am the Sheik Ahmed Ben Hassan." The name conveyed nothing. She had never heard it before. She had spoken without thinking in French, and in French he replied to her. "Why have you brought me here?" she asked, fighting down the fear that was growing more terrible every moment. He repeated her words with a slow smile. "Why have I brought you here? Bon Dieu! Are you not woman enough to know?" She shrank back further, a wave of colour rushing into her face that receded immediately, leaving her whiter than she had been before. Her eyes fell under the kindling flame in his. "I don't know what you mean," she whispered faintly, with shaking lips.
