The pace was less killing now. Silver Star had settled down into the steady tireless gallop for which Ahmed Ben Hassan's horses were famous. The little breeze had died away as quickly as it had sprung up, and it was very hot. Diana looked about her with glowing eyes. Everything seemed different. From the first she had loved the desert, but back of everything and mingled with everything had been the feeling of fear, the continual restraint, the perpetual subservience to the whims of her captor which had dominated everything. But now the whole aspect was changed. She loved the endless, undulating expanse stretching out before her, and as the grey topped each rise her interest grew keener. What might not be behind the next one? For an hour or more the ground rose and fell in monotonous succession, and then the desert grew level again and quite suddenly she could see for miles. About two miles away a few palm trees showed clustering together, and Diana turned in their direction. They probably meant a well, and it was time she rested her horse and herself. It was the tiniest little oasis, and she drew rein and dismounted with fears for the well she had hoped to find. But there was one, very much silted up, and she set to work to clear it as well as she could to procure enough for herself and Silver Star, who was frantically trying to get to the water. It was exhausting work, but she managed to satisfy the grey, and, having unloosed his girths, she flung herself down on the ground in a small patch of shade. She lit a cigarette and lay flat on her back with her helmet over her eyes.

For the first time since she had shaken off Gaston she began to think seriously. What she had done was madness. She had no food for herself or her horse, no water, and Heaven alone knew where the next well might be. She was alone in an uncivilised country among a savage people with no protection of any kind. She might fall in with friendly Arabs or she might not. She might come across an encampment, or she might wander for days and see no one, in which case death from hunger and thirst stared her in the face. What would she do when night came? With a sharp cry she leaped to her feet. What was she to do? She looked all around the little oasis with startled eyes, at the few palm trees and clumps of camel thorn, the broken well and the grey horse still snuffing about its mouth. She felt frightened for the first time; she was alone and about her was unending space, and she felt an atom, insignificant, the least of all things. She looked up into the clear sky and the blue vastness appalled her.

Then the sudden panic to which she had given way subsided and her courage rose with a bound. It was only midday, anything might happen between then and nightfall. Of one thing only she was sure, she did not repent of what she had done. Behind her was Ahmed Ben Hassan and before her was possibly death, and death was preferable. She was quite calm again and lay down in the patch of shade once more with a resolute determination to mind. Time to think of them when they came. For the next hour or two she must rest and escape the intense heat. She rolled over on her face with her head in her arms and tried to sleep, but she was too excited, and soon gave up the attempt. And in any case, she argued with herself, she might sleep too long and lose precious time. She stretched luxuriously on the soft ground, thankful for the shade from the burning sun. The grey, tired of nosing round the well and blowing disdainfully at the thorn bushes, wandered over to her side and nuzzled her gently. She caught at his velvety nose and drew it down beside her face. He was a very affectionate beast and gentler than most of the other horses, and he pressed close up to her, whinnying softly and looking at her with large expressive eyes. "I haven't anything to give you, poor old boy," she said regretfully, kissing his muzzle and then pushing him away from her. She looked up again into the sky, a dark speck sailed overhead, the slow heavy flight of a vulture. In a few hours he might be picking her bones! Merciful Heavens! Why did such thoughts come into her head? Had she nothing left of the courage that had once been second nature? If she let her nerves get the upper hand she might as well make no further effort, but lie down and die at once. With shaking fingers she took another cigarette; smoking would soothe her. Yet she hesitated before she lit it; there were only a few left and her need might still be greater. But with a reckless laugh she snapped the thin case to, and carefully scraped the evil-smelling sulphur match torn from a flat wood strip. She settled herself comfortably again full length. All around her were the innumerable tiny noises of the desert, the hum of countless insect life, the rustling of the sand and the occasional dry crackle of the camel thorns made by the slipping of a twig or the displacing of a branch, sounds that would have been incomprehensible some weeks before. For a few minutes a sand spider attracted her attention and she watched his hurried painstaking operations with wondering interest. Gradually a drowsy feeling stole over her and she realised suddenly that the air was impregnated with the scent of the tobacco that was always associated with the Sheik. It was one of his cigarettes that she was smoking. She had always been powerfully affected by the influence of smell, which induced recollection with her to an extraordinary degree, and now the uncommon penetrating odour of the Arab's cigarettes brought back all that she had been trying to put out of her mind. With a groan she flung it away and buried her face in her arms. The past rose up, and rushed, uncontrolled, through her brain. Incidents crowded into her recollection, memories of headlong gallops across the desert riding beside the man who, while she hated him, compelled her admiration, memories of him schooling the horses that he loved, sitting them like a centaur, memories of him amongst his men, memories more intimately connected with herself, of his varying moods, his swift changes from savage cruelty to amazing gentleness, from brutal intolerance to sudden consideration. There had even been times when he had interested her despite herself, and she had forgotten the relationship in which they stood towards each other in listening to his deep, slow voice, till a word or a gesture brought back the fact vividly. Memories of moments when she had struggled against his caresses, and he had mocked her helplessness with his great strength, when she had lain in his arms panting and exhausted, cold with fear and shrinking from his fierce kisses. She had feared him as she had never believed it possible to fear. His face rose before her clearly with all the expressions she had learned to know and dread. She tried to banish it, striving with all her might to put him from her mind, twisting this way and that, writhing on the soft sand as she struggled with the obsession that held her. She saw him all the time plainly, as though he were there before her. Would he pursue her always, phantom-like? Would the recollection of the handsome brown face haunt her for ever with its fierce eyes and cruel mouth? She buried her head deeper in her arms, but the vision persisted until with a scream she started up with heaving chest and wild eyes, standing rigid, staring towards the south with a desperate fixedness that made her eyeballs ache. The sense of his presence had been terribly real. She dropped on to the ground again with an hysterical laugh, and pushed the thick hair off her forehead wearily. Silver Star laying his muzzle suddenly on her shoulder made her start again violently with heavy, beating heart. A frightened look went across her face. "I'm nervous," she muttered, looking round with a little shiver. "I shall go mad if I stay here much longer." The little oasis that she had hailed so joyfully had become utterly repugnant and she was impatient to get away from it. She climbed eagerly into the saddle, and, with the rapid motion, she regained her calm and her spirits rose quickly.

She shook off the feeling of apprehension that had taken hold of her and her nervous fears died away. A reckless feeling, like the excitement of the morning, came over her, and she urged the grey on with coaxing words, and responding to her voice, and hardly feeling her light weight, he raced on untiringly. All around was silence and a solitude that was stupendous. The vast emptiness was awe-inspiring. The afternoon was wearing away; already it was growing cooler. Diana had seen no sign of human life since she had left Gaston hours before and a little feeling of anxiety stirred faintly deep down in her heart. Traces of caravans she passed several times, and from the whitening bones of dead camels she turned her head in aversion—they were too intimately suggestive. She had seen a few jackals, and once a hyena lumbered away clumsily among some rocks as she passed. She had got away from the level desert, and was threading her way in and out of some low hills, which she felt were taking her out of her right course. She was steering by the setting sun, which had turned the sky into a glory of golden crimson, but the intricate turnings amongst the rocky hills were bewildering. The low, narrow defile seemed hemming her in, menacing her on all sides, and she was beginning to despair of finding her way out of the labyrinth, when, on rounding a particularly sharp turn, the rocks fell away suddenly and she rode out into open country. She breathed a sigh of relief and called out cheerily to the grey, but, as she looked ahead, her voice died away, and she reined him in sharply with a quickening heart-beat. Across the desert about a mile away she saw a party of Arabs coming towards her. There were about fifty of them, the leader riding a big, black horse some little distance in front of his followers. In the clear atmosphere they seemed nearer than they were. It was not what she wished. She had hoped for an encampment, where there would be women or a caravan of traders whose constant communication with the towns would make them realise the importance of guiding her to civilisation unharmed. This band of fighting men, for she could see their rifles clearly, and their close and orderly formation was anything but peaceful, filled her with the greatest misgivings. Only the worst might be expected from the wild, lawless tribesmen towards a woman alone amongst them. She had fled from one hideousness to another which would be ten times more horrible. Her face blanched and she set her teeth in desperation. The human beings she had prayed for were now a deadly menace, and she prayed as fervently that they might pass on and not notice her. Perhaps it was not too late, perhaps they had not yet seen her and she might still slip away and hide in the twisting turnings of the defile. She backed Silver Star further into the shadow of the rock, but as she did so she saw that she had been seen. The leader turned in his saddle and raised his hand high above his head, and with a wild shout and a great cloud of dust and sand his men checked their horses, dragging them back on to their haunches, while he galloped towards her alone. And at the same moment an icy hand clutched at Diana's heart and a moan burst from her lips. There was no mistaking him or the big black horse he rode. For a moment she reeled with a sudden faintness, and then with a tremendous effort she pulled herself together, dragging her horse's head round and urged him back along the track which she had just left, and behind her raced Ahmed Ben Hassan, spurring the great, black stallion as he had never done before. With ashy face and wild, hunted eyes Diana crouched forward on the grey's neck, saving him all she could and riding as she had never ridden in her life. Utterly reckless, she urged the horse to his utmost pace, regardless of the rough, dangerous track. Perhaps she could still shake off her pursuer among the tortuous paths of the hills. Nothing mattered but that. Better even an ugly toss and a broken neck than that he should take her again. Panic-stricken she wanted to shriek and clenched her teeth on her lips to keep back the scream that rose in her throat. She dared not look behind, but straight ahead before her, riding with all her skill, hauling the grey round perilous corners and bending lower and lower in the saddle to aid him. In her terror she had forgotten what a little distance the hills stretched from where she had entered them, and blindly she turned into the track by which she had come, leaving the main hills on her right hand and emerging on to the open desert on the south side of the range. There was nothing now but the sheer speed of her horse to save her, and how long could she count on it? Then with a little glimmer of hope she remembered that the Sheik was riding The Hawk, own brother to the grey, and she knew that neither had ever outpaced the other. She had ridden hard all day, but it was probable that Ahmed Ben Hassan had ridden harder; he never spared his horses, and his weight was considerably greater than hers. Would it not be possible for Silver Star, carrying the lighter burden, to outdistance The Hawk? It was a chance. She would take it, but she would never give in. The perspiration was rolling down her face and her breath was coming laboriously. Suddenly, a few minutes after she had left the hills behind, the Sheik's deep voice came clearly across the space between them.

"If you do not stop I will shoot your horse. I give you one minute."

She swayed a little in the saddle, clutching the grey's neck to steady herself and for a moment she closed her eyes, but she did not falter for an instant. She would not stop; nothing on earth should make her stop now. Only, because she knew the man, she kicked her feet clear of the stirrups. He had said he would shoot and he would shoot, and if the grey shied or swerved a hair's breadth she would probably receive the bullet that was meant for him. Better that! Yes, even better that!

Silver Star tore on headlong and the minute seemed a lifetime. Then before even she heard the report he bounded in the air and fell with a crash. Diana was flung far forward and landed on some soft sand. For a moment she was stunned by the fall, then she staggered dizzily to her feet and stumbled back to the prostrate horse. He was lashing out wildly with his heels, making desperate efforts to rise. And as she reached him the black horse dashed up alongside, stopping suddenly, and rearing straight up. The Sheik leaped to the ground and ran towards her. He caught her wrist and flung her out of his way, and she lay where she had fallen, every nerve in her body quivering. She was beaten and with the extinguishing of her last hope all her courage failed her. She gave way to sheer, overwhelming terror, utterly cowed. Every faculty was suspended, swallowed up in the one dominating force, the dread of his voice and the dread of the touch of his hands. She heard a second report and knew that he had put Silver Star out of his misery, and then, in a few seconds, his voice beside her. She got up unsteadily, shrinking from him.

"Why are you here, and where is Gaston?"

In a stifled voice she told him everything. What did it matter? If she tried to be silent he would force her to speak.

He made no comment, and bringing The Hawk nearer tossed her up roughly into the saddle and swung up behind her, the black breaking at once into the usual headlong gallop. She made no kind of resistance, a complete apathy seemed to have come over her. She did not look at the body of Silver Star, she looked at nothing, clinging to the front of the saddle, and staring ahead of her unseeingly. She had dropped her helmet when she fell and she had left it, thankful to be relieved of the pressure on her aching head. Her mental collapse had affected her physically, and it needed a real effort of will-power to enable her to sit up right. Very soon they would join the horsemen, who were waiting for them, and for her pride's sake she must concentrate all her energy to avoid betraying her weakness.
