Diana threw the end of her cigarette at the lizard and laughed at its precipitant flight. She had no desire to follow the example of her escort and sleep. She was much too happy to lose a minute of her enjoyment by wasting it in rest that she did not require. She was perfectly content and satisfied with herself and her outlook. She had not a care or a thought in the world. There was not a thing that she would have changed or altered. Her life had always been happy; she had extracted the last ounce of pleasure out of every moment of it. That her happiness was due to the wealth that had enabled her to indulge in the sports and constant travel that made up the sum total of her desires never occurred to her. That what composed her pleasure in life was possible only because she was rich enough to buy the means of gratifying it did not enter her head. She thought of her wealth no more than of her beauty. The business connected with her coming of age, when the big fortune left to her by her father passed unreservedly into her own hands, was a wearisome necessity that had been got through as expeditiously as possible, with as little attention to detail as the old family lawyer had allowed, and an absence of interest that was evidenced in the careless scrawl she attached to each document that was given her to sign. The mere money in itself was nothing; it was only a means to an end. She had never even realised how much was expended on the continuous and luxurious expeditions that she had made with Sir Aubrey; her own individual tastes were simple, and apart from the expensive equipment that was indispensable for their hunting trips, and which was Aubrey's choosing, not hers, she was not extravagant. The long list of figures that had been so boring during the tedious hours that she had spent with the lawyer, grudging every second of the glorious September morning that she had had to waste in the library when she was longing to be out of doors, had conveyed nothing to her beyond the fact that in future when she wanted anything she would be put to the trouble of writing out an absurd piece of paper herself, instead of leaving the matter in Aubrey's hands, as she had done hitherto.
She had hardly understood and had been much embarrassed by the formal and pedantic congratulations with which the lawyer had concluded his business statement. She was not aware that she was an object of congratulation. It all seemed very stupid and uninteresting. Of real life she knew nothing and of the ordinary ties and attachments of family life less than nothing. Aubrey's cold, loveless training had debarred her from all affection; she had grown up oblivious of it. Love did not exist for her; from even the thought of passion she shrank instinctively with the same fastidiousness as she did from actual physical uncleanliness.
That she had awakened an emotion that she did not understand herself in certain men had been an annoyance that had become more intolerable with repetition. She had hated them and herself impartially, and she had scorned them fiercely. She had never been so gentle and so human with any one as she had been with Jim Arbuthnot, and that only because she was so radiantly happy that night that not even the distasteful reminder that she was a woman whom a man coveted was able to disturb her happiness. But here there was no need to dwell on annoyances or distasteful reminders.
Diana dug her heels into the soft ground with a little wriggle of content; here she would be free from anything that could mar her perfect enjoyment of life as it appeared to her. Here there was nothing to spoil her pleasure. Her head had drooped during her thoughts, and for the last few minutes her eyes had been fixed on the dusty tips of her riding-boots. But she raised them now and looked up with a great content in them. It was the happiest day of her life. She had forgotten the quarrel with Aubrey. She had put from her the chain of ideas suggested by the passing caravan. There was nothing discordant to disturb the perfect harmony of her mind.
A shade beside her made her turn her head. Mustafa Ali salaamed obsequiously. "It is time to start, Mademoiselle."
Diana looked up in surprise and then back over her shoulder at the escort. The men were already mounted. The smile faded from her eyes. Mustafa Ali was guide, but she was head of this expedition; if her guide had not realised this he would have to do so now. She glanced at the watch on her wrist.
"There is plenty of time," she said coolly.
Mustafa Ali salaamed again. "It is a long ride to reach the oasis where we must camp to-night," he insisted hurriedly.
Diana crossed one brown boot over the other, and scooping up some sand in the palm of her hand trickled it through her fingers slowly. "Then we can ride faster," she replied quietly, looking at the shining particles glistening in the sun.
Mustafa Ali made a movement of impatience and persisted doggedly.
"Mademoiselle would do well to start."
Diana looked up swiftly with angry eyes. Under the man's suave manner and simple words a peremptory tone had crept into his voice. She sat quite still, her fingers raking the warm sand, and under her haughty stare the guide's eyes wavered and turned away. "We will start when I choose, Mustafa Ali," she said brusquely. "You may give orders to your men, but you will take your orders from me. I will tell you when I am ready. You may go."
Still he hesitated, swaying irresolutely backwards and forwards on his heels.
Diana snapped her fingers over her shoulder, a trick she had learned from a French officer in Biskra. "I said go!" she repeated sharply. She took no notice of his going and did not look back to see what orders he gave the men. She glanced at her watch again. Perhaps it was growing late, perhaps the camp was a longer ride than she had thought; but Mustafa Ali must learn his lesson if they rode till midnight to reach the oasis. She pushed her obstinate chin out further and then smiled again suddenly. She hoped that the night would fall before they reached their destination. There had been one or two moonlight riding picnics out from Biskra, and the glamour of the desert nights had gone to Diana's head. This riding into the unknown away from the noisy, chattering crowd who had spoiled the perfect stillness of the night would be infinitely more perfect. She gave a little sigh of regret as she thought of it. It was not really practical. Though she would wait nearly another hour to allow the fact of her authority to sink into Mustafa Ali's brain she would have to hasten afterwards to arrive at the camp before darkness set in. The men were unused to her ways and she to theirs. She would not have Stephens' help to-night; she would have to depend on herself to order everything as she wished it, and it was easier done in daylight. One hour would not make much difference. The horses had more in them than had been taken out of them this morning; they could be pushed along a bit faster with no harm happening to them. She eyed her watch from time to time with a grin of amusement, but suppressed the temptation to look and see how Mustafa Ali was taking it, for her action might be seen and misconstrued.
When the time she had set herself was up she rose and walked slowly towards the group of Arabs. The guide's face was sullen, but she took no notice, and, when they started, motioned him to her side again with a reference to Biskra that provoked a flow of words. It was the last place she wanted to hear of, but it was one of which he spoke the readiest, and she knew it was not wise to allow him to remain silent to sulk. His ill-temper would evaporate with the sound of his own voice. She rode forward steadily, silent herself, busy with her own thoughts, heedless of the voice beside her, and unconscious of the fact when it became silent.
She had been quite right about the capabilities of the horses. They responded without any apparent effort to the further demand made of them. The one in particular that Diana was riding moved in a swift, easy gallop that was the perfection of motion.
They had been riding for some hours when they came to the first oasis that had been sighted since leaving the one where the midday halt was made. Diana pulled up her horse to look at it,
