Arbuthnot sat in silence. It was hardly likely, he thought bitterly, that he should succeed where other and better men had failed. He had been a fool to succumb to the temptation that had been too hard for him to resist. He knew her well enough to know beforehand what her answer would be. The very real fear for her safety that the thought of the coming expedition gave him, her nearness in the mystery of the Eastern night, the lights, the music, had all combined to rush to his lips words that in a saner moment would never have passed them. He loved her, he would love her always, but he knew that his love was as hopeless as it was undying. But it was men who were men whom she wanted for her friends, so he must take his medicine like a man.
"May I still be the pal, Diana?" he said quietly.
She looked at him a moment, but in the dim light of the hanging lanterns his eyes were steady under hers, and she held out her hand frankly. "Gladly," she said candidly. "I have hosts of acquaintances, but very few friends. We are always travelling, Aubrey and I, and we never seem to have time to make friends. We rarely stay as long in one place as we have stayed in Biskra. In England they call us very bad neighbours, we are so seldom there. We generally go home for three months in the winter for the hunting, but the rest of the year we wander on the face of the globe."
He held her slender fingers gripped in his for a moment, smothering an insane desire to press them to his lips, which he knew would be fatal to the newly accorded friendship, and then let them go. Miss Mayo continued sitting quietly beside him. She was in no way disturbed by what had happened. She had taken him literally at his word, and was treating him as the pal he had asked to be. It no more occurred to her that she might relieve him of her society than it occurred to her that her continued presence might be distressing to him. She was totally unembarrassed and completely un-self-conscious. And as they sat silent, her thoughts far away in the desert, and his full of vain longings and regrets, a man's low voice rose in the stillness of the night. "Pale hands I loved beside the Shalimar. Where are you now? Who lies beneath your spell?" he sang in a passionate, vibrating baritone. He was singing in English, and yet the almost indefinite slurring from note to note was strangely un-English. Diana Mayo leaned forward, her head raised, listening intently, with shining eyes. The voice seemed to come from the dark shadows at the end of the garden, or it might have been further away out in the road beyond the cactus hedge. The singer sang slowly, his voice lingering caressingly on the words; the last verse dying away softly and clearly, almost imperceptibly fading into silence.
For a moment there was utter stillness, then Diana lay back with a little sigh. "The Kashmiri Song. It makes me think of India. I heard a man sing it in Kashmere last year, but not like that. What a wonderful voice! I wonder who it is?"
Arbuthnot looked at her curiously, surprised at the sudden ring of interest in her tone, and the sudden animation of her face.
"You say you have no emotion in your nature, and yet that unknown man's singing has stirred you deeply. How do you reconcile the two?" he asked, almost angrily.
"Is an appreciation of the beautiful emotion?" she challenged, with uplifted eyes. "Surely not. Music, art, nature, everything beautiful appeals to me. But there is nothing emotional in that. It is only that I prefer beautiful things to ugly ones. For that reason even pretty clothes appeal to me," she added, laughing.
"You are the best-dressed woman in Biskra," he acceded. "But is not that a concession to the womanly feelings that you despise?"
"Not at all. To take an interest in one's clothes is not an exclusively feminine vice. I like pretty dresses. I admit to spending some time in thinking of colour schemes to go with my horrible hair, but I assure you that my dressmaker has an easier life than Aubrey's tailor."
She sat silent, hoping that the singer might not have gone, but there was no sound except a cicada chirping near her. She swung round in her chair, looking in the direction from which it came. "Listen to him. Jolly little chap! They are the first things I listen for when I get to Port Said. They mean the East to me."
"Maddening little beasts!" said Arbuthnot irritably.
"They are going to be very friendly little beasts to me during the next four weeks…. You don't know what this trip means to me. I like wild places. The happiest times of my life have been spent camping in America and India, and I have always wanted the desert more than either of them. It is going to be a month of pure joy. I am going to be enormously happy."
She stood up with a little laugh of intense pleasure, and half turned, waiting for Arbuthnot. He got up reluctantly and stood silent beside her for a few moments. "Diana, I wish you'd let me kiss you, just once," he broke out miserably.
She looked up swiftly with a glint of anger in her eyes, and shook her head. "No. That's not in the compact. I have never been kissed in my life. It is one of the things that I do not understand." Her voice was almost fierce.
She moved leisurely towards the hotel, and he paced beside her wondering if he had forfeited her friendship by his outburst, but on the verandah she halted and spoke in the frank tone of camaraderie in which she had always addressed him. "Shall I see you in the morning?"
He understood. There was to be no more reference to what had passed between them. The offer of friendship held, but only on her own terms. He pulled himself together.
"Yes. We have arranged an escort of about a dozen of us to ride the first few miles with you, to give you a proper send-off."
She made a laughing gesture of protest. "It will certainly need four weeks of solitude to counteract the conceit I shall acquire," she said lightly, as she passed into the ballroom.
A few hours later Diana came into her bedroom, and, switching on the electric lights, tossed her gloves and programme into a chair. The room was empty, for her maid had had a vertige at the suggestion that she should accompany her mistress into the desert, and had been sent back to Paris to await Diana's return. She had left during the day, to take most of the heavy luggage with her.
Diana stood in the middle of the room and looked at the preparations for the early start next morning with a little smile of satisfaction. Everything was en train; the final arrangements had all been concluded some days before. The camel caravan with the camp equipment was due to leave Biskra a few hours before the time fixed for the Mayos to start with Mustafa Ali, the reputable guide whom the French authorities had reluctantly recommended. The two big suit-cases that Diana was taking with her stood open, ready packed, waiting only for the last few necessaries, and by them the steamer trunk that Sir Aubrey would take charge of and leave in Paris as he passed through. On a chaise-longue was laid out her riding kit ready for the morning. Her smile broadened as she looked at the smart-cut breeches and high brown boots. They were the clothes in which most of her life had been spent, and in which she was far more at home than in the pretty dresses over which she had laughed with Arbuthnot.
She was glad the dance was over; it was not a form of exercise that appealed to her particularly. She was thinking only of the coming tour. She stretched her arms out with a little happy laugh.
"It's the life of lives, and it's going to begin all over again to-morrow morning." She crossed over to the dressing-table, and, propping her elbows on it, looked at herself in the glass, with a little friendly smile at the reflection. In default of any other confidant she had always talked to herself, with no thought for the beauty of the face staring back at her from the glass. The only comment she ever made to herself on her own appearance was sometimes to wish that her hair was not such a tiresome shade. She looked at herself now with a tinge of curiosity. "I wonder why I'm so especially happy to-night. It must be because we have been so long in Biskra. It's been very jolly, but I was beginning to get very bored." She laughed again and picked up her watch to wind. It was one of her peculiarities that she would wear no jewellery of any kind. Even the gold repeater in her hand was on a plain leather strap. She undressed slowly and each moment felt more wide-awake. Slipping a thin wrap over her pyjamas and lighting a cigarette she went out on to the broad balcony on to which her bedroom gave. The room was on the first floor, and opposite her window rose one of the
