"He is rightly named Shaitan, Madame, for he is assuredly possessed of a devil," he said, indicating the chestnut, who, at that moment, with a violent plunge, broke away from the men who were holding him and headed for the edge of the oasis with the Arabs streaming after him. "The mounted men will catch him," he added with a little laugh, in response to Diana's exclamation.
"Is he amusing himself, or is it really vice?" she asked.
"Pure vice, Madame. He has killed three men."
Diana looked at him incredulously, for his tone was casual and his manner did not indicate any undue feeling.
"He ought to be shot," she said indignantly.
The man shrugged. "Monseigneur is fond of him," he said quietly.
And so because Monseigneur was fond of him the vicious animal was surrounded with every care that his master's pleasure might not be interfered with. Evidently the lives of his wretched people were of less value to him than that of a favourite horse. It sounded compatible with the mercilessness she had herself experienced. What she would not have believed yesterday to-day seemed terribly credible. The courage that the relief of his absence brought back was sinking fast, as fast as the red ball glowing in the heavens was sinking down towards the horizon. She turned from her own fearful thoughts to look at some more horses that were being led away to the lines on the other side of the camp.
"The horses are magnificent, but they are bigger than any Arabs I have seen before."
"They are a special breed, Madame," replied the Frenchman. "The tribe has been famous for them for generations. Monseigneur's horses are known through all the Barbary States, and as far as France," he added, with a little accent of pride creeping into his voice.
Diana looked at him speculatively. There was an inflection in his voice each time he mentioned his master that indicated a devotion that she was unable to accredit to the brute for whose treatment she was still suffering. But her thoughts were broken into abruptly.
"There is Monseigneur," said the servant suddenly. He spoke as if she, too, must be glad of his coming. Did the valet imagine for one moment that she was here of her own free will? Or was it all a part of the hypocrisy in which she seemed to be enveloped? She flashed one glance at the horseman riding through the belt of trees that fringed the oasis and an icy perspiration chilled her from head to foot. She shrank back under the awning and into the coolness of the tent, raging against the mastering fear that she could not overcome. But just inside the open doorway she stood firm; even her fear could make her go no further. She would meet him here, not cowering into the inner room like a trembling creature skulking in the furthest corner of its cage. That much pride at least was left.
From the shelter of the tent she watched the troop arrive at the open space before her. The horse the Sheik was riding was jet black, and Diana looked from the beautiful creature's satiny coat to the man's white robes with angry contempt.
"Black and white! Black and white! Mountebank!" she muttered through her clenched teeth. Then as he swung to the ground every thought fell from her but the terror he inspired. She waited, breathless, the swift racing of her heart an actual physical pain.
He lingered, fondling the great black horse, and even after it had been led away he stood looking after it, talking to a tall young Arab who had ridden in with him. At last he turned and came leisurely towards the tent. He paused at the door to speak to the Frenchman, a picturesque, barbaric figure, with flowing robes and great white cloak, the profile of his lean face clean cut against the evening sky, the haughty poise of his head emphasised by the attitude in which he was standing, arrogant, dominating. He moved his hands when he spoke with quick, expressive gestures, but his voice was slow and soft, pitched in a deep musical key, but with all its softness unmistakably authoritative. He pointed with outstretched, steady hand to something beyond her line of vision, and as he turned to enter the tent he laughed softly, and she shivered involuntarily. Then he swept in, and she drew back from him with lowered eyes. She would not look at him; she would not meet his look. His presence was an offence, she was scorched with shame. Every fibre of her being cried out in protest at his proximity. She wished with passionate fierceness that she could die. She shook feverishly and caught her quivering lip between her teeth to keep it still, and the red-gold curls lay wet against her forehead. Her breast heaved stormily with the rapid beating of her heart, but she held herself proudly erect. He crossed the tent with a long noiseless stride.
"I hope that Gaston took care of you properly and gave you everything that you wanted?" he said easily, stooping to a little table to light a cigarette. The coolness of his words and manner were like a dash of cold water. She had been prepared for anything but this calm nonchalance in a situation that was intolerable. His tone conveyed the perfunctory regret of a host for an unavoidable absence. Her fear gave way to rage, her body stiffened, her hands clenched.
"Is it not time that this ended? Haven't you done enough?" she burst out passionately. "Why have you committed this outrage?"
A thin thread of smoke drifted towards her, as if the hand holding the cigarette had moved in her direction in one of the gestures that she had noticed outside, but there was no answer. His silence infuriated her and she grew utterly reckless.
"Do you think that you can keep me here, you fool? That I can vanish into the desert and no notice be taken of my disappearance—that no inquiries will be made?"
"There will be no inquiries," he answered calmly.
She ground the heel of her boot into the soft carpet. "There will be inquiries," she choked furiously. "I am not such a nonentity that nothing will be done when I am missed. The English authorities will make the French Government find out who is responsible, and you will have to pay for what you have done."
He laughed—the little amused laugh that sent the same cold feeling of dread through her that she had felt the day before.
"The French Government has no jurisdiction over me. I am not subject to it. I am an independent chief, my own master. I recognise no government. My tribe obey me and only me."
