Having made up his mind to go through with a proceeding that he regarded in the light of a sacrifice on the family altar, his wish was to get it over and done with as soon as possible, and Diana's interference in his plans had exasperated him. It was the first time that their wills had crossed, and she shrugged her shoulders impatiently, with a grimace at the recollection. A little more and it would have degenerated into a vulgar quarrel. She banished Aubrey and his selfishness resolutely from her mind. It was very hot, and she lay very still in the narrow cot, wishing she had not been so rigid in the matter of its width, and wondering if a sudden movement in the night would precipitate her into the bath that stood alongside. She thought regretfully of a punkah, and then smiled derisively at herself.
"Sybarite!" she murmured sleepily. "You need a few discomforts."
She was almost aggressively cheerful next morning at breakfast and for the time that they lingered at the oasis after the baggage camels had started. Sir Aubrey was morose and silent, and she exchanged most of her badinage with Stephens, who was superintending the packing of the tiffin basket that would accompany her in charge of the man who had been selected as her personal servant, and who was waiting, with Mustafa Ali and about ten men, to ride with her.
The time for starting came. Stephens was fussing about the horse that
Diana was to ride.
"Everything all right, Stephens? Up to your standard? Don't look so glum. I wish you were coming to look after me, but it couldn't be done. Sir Aubrey would be lost without you."
The idea of a tour without Stephens in the background seemed suddenly momentous, and the smile she gave him was more serious than she meant it to be. She went back to her brother, who was pulling his moustache savagely. "I don't think there's any use waiting any longer. You won't want to hurry yourself too much, and you will want to be in Biskra in time for dinner," she said as casually as she could.
He swung towards her. "Diana, it's still not too late to change your mind. For Heaven's sake give up this folly. It's tempting Providence." For the first time there was a genuine ring in his voice, and for a moment Diana wavered, but only for a moment. Then she looked at him with a slow smile.
"Do I fall on your neck and say, 'Take me back, dear Guardian; I will be good,' or do I prostrate myself at your feet and knock my head on your boots, and whine, in the language of the country, 'Hearing is obeying'? Don't be ridiculous, Aubrey. You can't expect me to change my mind at the eleventh hour. It's perfectly safe. Mustafa Ali will take care that everything goes smoothly. He has his reputation in Biskra to think of. You know the character the authorities gave him. He is not likely to throw that away. In any case I can take care of myself, thanks to your training. I don't mind owning to being conceited about my shooting. Even you admit that I am a credit to your teaching."
With a gay little laugh she whipped out the ivory-mounted revolver, and aiming at a low flat rock, some distance away, fired. She was an unusually good revolver shot, but this time she seemed to have missed. There was no mark on the stone. Diana stared at it stupidly, a frown of perplexity creasing her forehead. Then she looked at her brother, and back to the revolver in her hand.
Sir Aubrey swore. "Diana! What a senseless piece of bravado!" he cried angrily.
She took no notice of him. She was still staring at the smooth rock fate. "I don't understand it. How could I miss? It's as big as a house," she murmured thoughtfully, and raised the revolver again.
But Sir Aubrey caught her wrist. "For God's sake don't make a fool of yourself a second time. You have lowered your prestige quite enough already," he said in a low voice, with a glance at the group of watching Arabs.
Diana jerked the little weapon back into its place reluctantly. "I don't understand it," she said again. "It must be the light." She mounted and wheeled her horse alongside of Sir Aubrey's, and held out her hand. "Good-bye, Aubrey. Expect me a month after you arrive. I will cable to you from Cherbourg. Good luck! I shall roll up in time to be best man," she added, laughing, and with a nod to Mustafa Ali she turned her horse's head southwards.
For a long time she rode in silence. The quarrel with Aubrey had left a nasty taste in her mouth. She knew that what she was doing was considered unconventional, but she had been brought up to be unconventional. She had never even thought, when she planned her tour, of possible criticism; it would have made no difference to her if she had thought, and she had been amazed and amused at the sensation that her proposed trip had caused. The publicity to which it had given rise had annoyed her intensely; she had been scornful that people could not occupy themselves with their own affairs and leave her to deal with hers. But that Aubrey should join in the general criticism and present such a complete volte-face to the opinions he had always held was beyond her comprehension. She was angry with him, and contempt was mingled with her anger. It was inconsistent with the whole of his lifelong attitude toward her, and the discovery of his altered ideas left her rather breathless and more than ever determined to adhere to her own deeply-rooted convictions. Aubrey was responsible for them, he had instilled them, and if he chose now to abandon them that was his look-out. For her own part she saw no reason to change principles she had been brought up in. If Aubrey really thought there was danger in this expedition he could have sacrificed himself for once and come with her. As Jim Arbuthnot had said, it was only a month, a negligible length of time, but Aubrey's selfishness would not allow him to make that concession any more than her own obstinacy would allow her to give way. It was too much to expect. And this was the desert! It was the expedition that she had dreamed of and planned for years. She could not give it up. The idea of danger brought a little laugh to her lips. How could anything in the desert hurt her? It had been calling to her always. There was nothing strange about the scene that lay all around her. Her surroundings seemed oddly familiar. The burning sun overhead in the cloudless sky, the shimmering haze rising from the hot, dry ground, the feathery outline of some clustering palm trees in a tiny distant oasis were like remembrances that she watched again with a feeling of gladness that was fuller and deeper than anything that she had been conscious of before. She was radiantly happy—happy in the sense of her youth and strength, her perfect physical fitness, happy in the capacity of her power of enjoyment, happy with the touch of the keen, nervous horse between her knees, exhilarated with her new authority. She had looked forward so eagerly, and realisation was proving infinitely greater than anticipation. And for a whole month this perfect happiness was to be hers. She thought of her promise to Aubrey with impatience. To give up the joyous freedom of the desert for the commonplace round of American social life seemed preposterous. The thought of the weeks in New York were frankly tedious; Newport would be a little less bad, for there were alleviations. The only hope was that Aubrey would find the wife he was looking for quickly and release her from an obligation that was going to be very wearisome. Aubrey was counting on her, and it would be unsporting to let him down; she would have to keep her promise, but she would be glad when it was over. Aubrey married would settle definitely the possibility of any further disagreements between them. She wondered vaguely what the future Lady Mayo would be like, but she did not expend much pity on her. American girls as a rule were well able to care for themselves. She stroked her horse with a little smile. Aubrey and his possible wife seemed singularly uninteresting beside the vivid interest of the moment. A caravan that had been visible for a long time coming towards them drew nearer, and Diana reined in to watch the long line of slow, lurching camels passing. The great beasts, with their disdainful tread and long, swaying necks, never failed to interest her. It was a large caravan; the bales on the camels' backs looked heavy, and beside the merchants on riding camels and a motley crowd of followers—some on lean little donkeys and others on foot—there was an armed guard of mounted men. It took some time to pass. One of two of the camels carried huddled figures, swathed and shapeless with a multitude of coverings, that Diana knew must be women. The contrast between them and herself was almost ridiculous. It made her feel stifled even to look at them. She wondered what their lives were like, if they ever rebelled against the drudgery and restrictions that were imposed upon them, if they ever longed for the
