Ahmed Ben Hassan did not go back through the defile, he turned into a little path that Diana had overlooked and which skirted the hills. In about half-an-hour the troop met them, riding slowly from the opposite direction. She did not raise her eyes as they approached, but she heard Yusef's clear tenor voice calling out to the Sheik, who answered shortly as the men fell in behind him. Back over the ground that she had traversed so differently. She knew that it had been madness from the first. She should have known that it could never succeed, that she could never reach civilisation alone. She had been a fool ever to imagine that she could win through. The chance that had thrown her again into the Sheik's power might just as easily have thrown her into the hands of any other Arab. Luck had helped Ahmed Ben Hassan even as she herself had unknowingly played into his hands when he had captured her first. Fate was with him. It was useless to try and struggle against him any more. Her brain was a confused medley of thoughts that she was too tired to unravel, strange, conflicting ideas chasing wildly through her mind. She did not understand them, she did not try. The effort of thinking made her head ache agonisingly. She was conscious of a great unrest, a dull aching in her heart and a terrible depression that was altogether apart from the fear she felt of the Sheik.

She was drooping wearily, unable to sit upright any longer, and once or twice she jolted heavily against the man who rode behind her. His nearness had ceased to revolt her; she thought of it with a dull feeling of wonder. She had even a sense of relief at the thought of the strength so close to her. Her eyes rested on his hands, showing brown and muscular under the folds of his white robes. She knew the power of the long, lean fingers that could, when he liked, be gentle enough. Her eyes filled with sudden tears, but she blinked them back before they fell. She wanted desperately to cry. A wave of terrible loneliness went over her, a feeling of desolation, and a strange, incomprehensible yearning for what she did not know. As the sunset faded and it grew rapidly dusk a chill wind sprang up and she shivered from time to time, drooping more and more with fatigue, at times only half conscious. She had drifted into complete oblivion, when
