He was too engrossed to notice the usual noise in the camp that heralded the Sheik's arrival, and he looked up with a start when Ahmed Ben Hassan swept in. The Sheik's dark eyes glanced sombrely around the tent and without a word he went through into the inner room. In a moment he came hack.

"Where is Diane?"

Saint Hubert got up, puzzled at his tone. He looked at his watch. "She went for a ride this morning. Dieu! I had no idea it was so late."

"This morning!—and not back yet?" repeated the Sheik slowly. "What time this morning?"

"About ten, I think," replied Saint Hubert uneasily. "I'm not sure. I didn't look. There was an accident, and she delayed to watch me tie up one of your foolish children who had been playing with a worthless gun."

The Sheik moved over to the doorway. "She had an escort?" he asked curtly.

"Yes."

Ahmed Ben Hassan's face hardened and the heavy scowl contracted his black brows. Had she all these weeks been tricking him—feigning a content she did not feel, lulling his suspicions to enable her to seize another opportunity to attempt to get away? For a moment his face grew dark, then he put the thought from him. He trusted her. Only a week before she had given him her word, and he knew she would not lie to him. And, besides, the thing was impossible. Gaston would never be caught napping a second time, and there were also the six men who formed her guard. She would never be able to escape the vigilance of seven men. But it was the trust he had in her that weighed most with him. He had never trusted a woman before, but this woman had been different. The others who had come and gone so lightly had not even left a recollection behind them; they had faded into one concrete cause of utter boredom. There had never been any reason to trust or mistrust them, or to care if they came or went. Satiety had come with possession and with it indifference. But the emotion that this girl's uncommon beauty and slender boyishness had aroused in him had not diminished during the months she had been living in his camp. Her varying moods, her antagonism, her fits of furious rage, and, lastly, her unexpected surrender, had kept his interest alive. He had grown accustomed to her. He had come to looking forward with a vague, indefinite pleasure, on returning from his long expeditions, to seeing the dainty little figure curled up among the cushions on the big divan. Her presence seemed to pervade the atmosphere of the whole tent, changing it utterly. She had become necessary to him as he had never believed it possible that a woman could be. And with the change that she had made in his camp there had come a change in himself also.

For the first time a shadow had risen between him and the man whose friendship had meant everything to him since, as a lad of fifteen, he had come under the influence of the young Frenchman, who was three years his senior. He realized that since the night of Raoul's arrival he had been seething with insensate jealousy. He had relied on the Western tendencies that prompted him to carry off the difficult situation, but his ingrained Orientalism had broken through the superficial veneer. He was jealous of every word, every look she gave Saint Hubert. Pride had prevented an open rupture with the Vicomte this morning, but he had ridden away filled with a cold rage that had augmented every hour and finally driven him back earlier than he had intended, riding with a recklessness that had been apparent even to his men. The sight of Raoul sitting alone absorbed in his work had in part allayed his suspicions, and he had gone on into the other room with a feeling of new expectancy that had changed to a sudden chill at its emptiness. The vacant room had brought home to him abruptly all that the girl meant to him. A latent anxiety crept into his eyes.

He went out under the awning and clapped his hands, and a servant answered the summons almost immediately. He gave an order and waited, his hands thrust into the folds of his waist-cloth and his teeth clenched on a cigarette that he had forgotten to light.
