He felt her move and glanced down. For a moment she looked straight into his eyes, and then with a low, inarticulate murmur she hid her face against him. He did not speak, but he shifted her weight a little, drawing her closer into the curve of his arm.
It was very late when they reached the camp. Lights flashed up in the big tent and on all sides, and they were surrounded by a crowd of excited tribesmen and servants. In spite of the hard day's work The Hawk started plunging and rearing, his invariable habit on stopping, which nothing could break, and at a word from the Sheik two men leaped to his head while he transferred Diana to Yusef's outstretched arms. She was stiff and giddy, and the young man helped her to the door of the tent, and then vanished again into the throng of men and horses.
Diana sank wearily on to the divan and covered her face with her hands. She was trembling with fatigue and apprehension. What would he do to her? She asked herself the question over and over again, with shaking, soundless lips, praying for courage, nerving herself to meet him. At last she heard his voice and, looking up, saw him standing in the doorway. His back was turned, and he was giving orders to a number of men who stood near him, for she could hear their several voices; and shortly afterwards half-a-dozen small bands of men rode quickly away in different directions. For a few moments he stood talking to Yusef and then came in. At the sight of him Diana shrank back among the soft cushions, but he took no notice of her, and, lighting a cigarette, began walking up and down the tent. She dared not speak to him, the expression on his face was terrible.
Two soft-footed Arab servants brought a hastily prepared supper. It was a ghastly meal. He never spoke or showed in any way that he was conscious of her presence. She had had nothing to eat all day, but the food nearly choked her and she could hardly swallow it, but she forced herself to eat a little. It seemed interminable until the servants finally withdrew, after bringing two little gold-cased cups of native coffee. She gulped it down with difficulty. The Sheik had resumed his restless pacing, smoking cigarette after cigarette in endless succession. The monotonous tramp to and fro worked on Diana's nerves until she winced each time he passed her, and, huddled on the divan, she watched him continually, fascinated, fearful.
He never looked at her. From time to time he glanced at the watch on his wrist and each time his face grew blacker. If he would only speak! His silence was worse than anything he could say. What was he going to do? He was capable of doing anything. The suspense was torture. Her hands grew clammy and she wrenched at the soft open collar of her riding-shirt with a feeling of suffocation.
Twice Yusef came to report, and the second time the Sheik came back slowly from the door where he had been speaking to him and stopped in front of Diana, looking at her strangely.
She flung out her hands instinctively, shrinking further back among the cushions, her eyes wavering under his. "What are you going to do to me?" she whispered involuntarily, with dry lips.
He looked at her without answering for a while, as if to prolong the torture she was enduring, and a cruel look crept into his eyes. "That depends on what happens to Gaston," he said at length slowly.
"Gaston?" she repeated stupidly. She had forgotten the valet, in all that had occurred since the morning she had forgotten his very existence.
"Yes—Gaston," he said sternly. "You do not seem to have thought of what might happen to him."
She sat up slowly, a puzzled look coming into her face. "What could happen to him?" she asked wonderingly.
He dragged back the flap of the tent and pointed out into the darkness. "Over there in the south-west, there is an old Sheik whose name is Ibraheim Omair. His tribe and mine have been at feud for generations. Lately I have learned that he has been venturing nearer than he has ever before dared. He hates me. To capture my personal servant would be more luck than he could have hoped for."
He dropped the flap and began walking up and down again. There was a sinister tone in his voice that made Diana suddenly comprehend the little Frenchman's peril. Ahmed Ben Hassan was not the man to be easily alarmed on any one's behalf. That he was anxious about Gaston was apparent, and with her knowledge of him she understood his anxiety argued a very real danger. She had heard tales before she left Biskra, and since then she had been living in an Arab camp, and she knew something of the fiendish cruelty and callous indifference to suffering of the Arabs. Ghastly mental pictures with appalling details crowded now into her mind. She shuddered.
"What would they do to him?" she asked shakily, with a look of horror.
The Sheik paused beside her. He looked at her curiously and the cruelty deepened in his eyes. "Shall I tell you what they would do to him?" he said meaningly, with a terrible smile.
She gave a cry and flung her arms over her head, hiding her face. "Oh, do not! Do not!" she wailed.
He jerked the ash from his cigarette. "Bah!" he said contemptuously. "You are squeamish."
She felt sick with the realisation of what could result to Gaston from her action. She had had no personal feeling with regard to him. On the contrary, she liked him—she had not thought of him, the man, when she had stampeded his horse and left him on foot so far from camp. She had looked upon him only as a jailer, his master's deputy.
The near presence of this hostile Sheik explained many things she had not understood: Gaston's evident desire daring their ride not to go beyond a certain distance, the special activity that had prevailed of late amongst the Sheik's immediate followers, and the speed and silence that had been maintained during the headlong gallop across the desert that evening. She had known all along the Arab's obvious affection for his French servant, and it was confirmed now by the anxiety that he did not take the trouble to conceal—so unlike his usual complete indifference to suffering or danger.
