She thought of it all, sitting on the broad rail of the balcony, her head slanted against the column on which she leaned. “It’s been a splendid life,” she murmured. “and to-morrow—to-day begins the most perfect part of it.” She yawned and realised suddenly that she was desperately sleepy. She turned back into her room, leaving the windows wide, and, flinging off her wrap, tumbled into bed and slept almost before he head was on the pillow.
It must have been about an hour later when she awoke, suddenly wide awake. She lay quite still, looking cautiously under her thick lashes. The room was flooded with moonlight, there was nothing to be seen, but she had the positive feeling that there was another presence in the room beside her own; she had had a half-conscious vision in the moment of waking of a shadowy something that had seemed to fade away by the window. As the actual reality of this thought pierced through the sleep that dulled her brain and became a concrete suggestion, she sprang out of the bed and ran on to the balcony. It was empty. She leaned over the railing, listening intently, but she could see nothing and hear nothing. Puzzled, she went back into her room and turned on the lights. Nothing seemed to be missing: her watch lay where she had left it on the dressing table; and the suit-cases had apparently not been tampered with. By the bedside the ivory-mounted revolver that she always carried was lying as she had placed it. She looked around the room again, frowning. “It must have been a dream,” she said doubtfully, “but it seemed very real. It looked tall and white and solid, and I felt it there.” She waited a moment or two, then shrugged her shoulders, turned out the lights, and got into bed. Her nerves were admirable, and in five minutes she was asleep again.
CHAPTER II
The promised send-off had been enthusiastic. The arrangements for the trip had been perfect; there had been no hitch anywhere. The guide, Mustafa Ali, appeared capable and efficient, effacing himself when not wanted and replying with courteous dignity when spoken to. The day had been full of interest, and the long, hot ride had for Diana been the height of physical enjoyment. They had reached the oasis where the first night was to be passed an hour before, and found the camp already established, tents pitched, and everything so ordered that Sir Aubrey could find nothing to criticise; even Stephens, his servant, who had travelled with him since Diana was a baby, and who was as critical as his master on the subject of camps, had no fault to find.
Diana glanced about her little travelling tent with complete content. It was much smaller than the ones to which she had always been accustomed, ridiculously so compared with the large one she had had in India the previous year, with its separate bath- and dressing-rooms. Servants, too, had swarmed in India. Here service promised to be inadequate, but it had been her whim on this tour to dispense with the elaborate arrangements that Sir Aubrey cultivated and to try comparative roughing it. The narrow camp cot, the tin bath, the little folding table and her two suit-cases seemed to take up all the available space. But she laughed at the inconvenience, though she had drenched her bed with splashing, and the soap had found its way into the toe of one of her long boots. She had changed from her riding clothes into a dress of clinging jade-green silk, swinging short above her slender ankles, the neck cut low, revealing the gleaming white of her soft, girlish bosom. She came out of the tent and stood a moment exchanging an amused smile with Stephens, who was hovering near dubiously, one eye on her and the other on his master. She was late, and Sir Aubrey liked his meals punctually. The baronet was lounging in one deck-chair with his feet on another.
Diana wagged an admonishing forefinger. “Fly Stephens, and fetch the soup! If it is cold there will be a riot.” She walked to the edge of the canvas cloth that had been thrown down in front of the tents and stood revelling in the scene around her, her eyes dancing with excitement as they glanced slowly around the camp spread out over the oasis—the clustering palm trees, the desert itself stretching away before her in undulating sweeps, but seemingly level in the evening light, far off to the distant hills lying like a dark smudge against the horizon. She drew a long breath. It was the desert at last, the desert that she felt she had been longing for all her life. She had never known until this moment how intense the longing had been. She felt strangely at home, as if the great, silent emptiness had been waiting for her as she had been waiting for it, and now that she had come it was welcoming her softly with the faint rustle of the whispering sand, the mysterious charm of its billowy, shifting surface that seemed beckoning to her to penetrate further and further into its unknown obscurities.
Her brother’s voice behind her brought her down to earth suddenly. “You’ve been a confounded long time.”
She turned to the table with a faint smile. “Don’t be a bear, Aubrey. It’s all very well for you. You have Stephens to lather your chin and to wash your hands, but thanks to that idiot Marie, I have to look after myself.”
Sir Aubrey took his heels down leisurely from the second chair, pitched away his cigar, and, screwing his eyeglass into his eye with more than usual truculence, looked at her with disapproval. “Are you going to rig yourself out like that every evening for the benefit of Mustafa Ali and the camel-drivers?”
“I do not propose to invite the worthy Mustafa to meals, and I am not in the habit of ‘rigging myself out,’ as you so charmingly put it, for any one’s benefit. If you think I dress in camp to please you, my dear Aubrey, you flatter yourself. I do it entirely to please myself. That explorer woman we met in London that first year I began travelling with you explained to me the real moral and physical value of changing into comfortable, pretty clothes after a hard day in breeches and boots. You change yourself. What’s the difference?”
“All the difference,” he snapped. “There is no need for you to make yourself more attractive than you are already.”
“Since when has it occurred to you that I am attractive? You must have a touch of the sun, Aubrey,” she replied, with uplifted eyebrows, drumming impatiently with her fingers on the table.
“Don’t quibble. You know perfectly well that you are good-looking—too good-looking to carry through this preposterous affair.”
“Will you please tell me what you are driving at?” she asked quietly. But the dark blue eyes fixed on her brother’s face were growing darker as she looked at him.
“I’ve been doing some hard thinking to-day, Diana. This tour you propose is impossible.”
“Isn’t it rather late in the day to find that out?” she interrupted sarcastically; but he ignored the interruption.
“You must see for yourself, now that you are face to face with the thing, that it is impossble. It’s quite unthinkable that you can wander for the next month all alone in the desert with those damned niggers. Though my legal guardianship over you terminated last September I still have some moral obligations towards you. Though it has been convenient to me to bring you up as a boy and to regard you in the light of a younger brother instead of a sister, we cannot get away from the fact that you are a woman, and a very young woman. There are certain things a young woman cannot do. If you had been the boy I always wished you were it would have been a different matter, but you are not a boy, and the whole thing is impossible—utterly impossible.” There was a fretful impatience in his voice.
Diana lit a cigarette slowly, and swung round on her chair with a hard laugh. “If I had not lived with you all my life, Aubrey, I should really be impressed with your brotherly solicitude; I should think you really meant it. But knowing you as I do, I know that it is not anxiety on my behalf that is prompting you, but the disinclination that you have to travel alone without me. You have come to depend on me to save you certain annoyances and inconveniences that always occur in travelling. You were more honest in Biskra when you only objected to my trip without giving reasons. Why have you waited until to-night to give me those reasons?”
“Because
