"It doesn't matter when you have a banking account the size of his," said Arbuthnot. "Personally, I find dancing more amusing and less expensive. I shall go and take my chance with our hostess."
His eyes turned rather eagerly towards the end of the room where the girl was standing alone, straight and slim, the light from an electrolier gilding the thick bright curls framing her beautiful, haughty little face. She was staring down at the dancers with an absent expression in her eyes, as if her thoughts were far away from the crowded ballroom.
The American pushed Arbuthnot forward with a little laugh.
"Run along, foolish moth, and get your poor little wings singed. When the cruel fair has done trampling on you I'll come right along and mop up the remains. If, on the other hand, your temerity meets with the success it deserves, we can celebrate suitably later on." And, linking his arm in his friend's, he drew him away to the card-room.
Arbuthnot went through the window and worked slowly round the room, hugging the wall, evading dancers, and threading his way through groups of chattering men and women of all nationalities. He came at last to the raised dais on which Diana Mayo was still standing, and climbed up the few steps to her side.
"This is luck, Miss Mayo," he said, with an assurance that he was far from feeling. "Am I really fortunate enough to find you without a partner?"
She turned to him slowly, with a little crease growing between her arched eyebrows, as if his coming were inopportune and she resented the interruption to her thoughts, and then she smiled quite frankly.
"I said I would not dance until everybody was started," she said rather doubtfully, looking over the crowded floor.
"They are all dancing. You've done your duty nobly. Don't miss this ripping tune," he urged persuasively.
She hesitated, tapping her programme-pencil against her teeth.
"I refused a lot of men," she said, with a grimace. Then she laughed suddenly. "Come along, then. I am noted for my bad manners. This will only be one extra sin."
Arbuthnot danced well, but with the girl in his arms he seemed suddenly tongue-tied. They swung round the room several times, then halted simultaneously beside an open window and went out into the garden of the hotel, sitting down on a wicker seat under a gaudy Japanese hanging lantern. The band was still playing, and for the moment the garden was empty, lit faintly by coloured lanterns, festooned from the palm trees, and twinkling lights outlining the winding paths.
Arbuthnot leaned forward, his hands clasped between his knees.
"I think you are the most perfect dancer I have ever met," he said a little breathlessly.
Miss Mayo looked at him seriously, without a trace of self-consciousness.
"It is very easy to dance if you have a musical ear, and if you have been in the habit of making your body do what you want. So few people seem to be trained to make their limbs obey them. Mine have had to do as they were told since I was a small child," she answered calmly.
The unexpectedness of the reply acted as a silencer on Arbuthnot for a few minutes, and the girl beside him seemed in no hurry to break the silence. The dance was over and the empty garden was thronged for a little time. Then the dancers drifted back into the hotel as the band started again.
"It's rather jolly here in the garden," Arbuthnot said tentatively. His heart was pounding with unusual rapidity, and his eyes, that he kept fixed on his own clasped hands, had a hungry look growing in them.
"You mean that, you want to sit out this dance with me?" she said with a boyish directness that somewhat nonplussed him.
"Yes," he stammered rather foolishly.
She held her programme up to the light of the lantern. "I promised this one to Arthur Conway. We quarrel every time we meet. I cannot think why he asked me; he disapproves of me even more than his mother does—such an interfering old lady. He will be overjoyed to be let off. And I don't want to dance to-night. I am looking forward so tremendously to to-morrow. I shall stay and talk to you, but you must give me a cigarette to keep me in a good temper."
His hand shook a little as he held the match for her. "Are you really determined to go through with this tour?"
She stared at him in surprise. "Why not? My arrangements have been made some time. Why should I change my mind at the last moment?"
"Why does your brother let you go alone? Why doesn't he go with you?
Oh, I haven't any right to ask, but I do ask," he broke out vehemently.
She shrugged her shoulders with a little laugh. "We fell out, Aubrey and I. He wanted to go to America. I wanted a trip into the desert. We quarrelled for two whole days and half one night, and then we compromised. I should have my desert tour, and Aubrey should go to New York; and to mark his brotherly appreciation of my gracious promise to follow him to the States without fail at the end of a month he has consented to grace my caravan for the first stage, and dismiss me on my way with his blessing. It annoyed him so enormously that he could not order me to go with him, this being the first time in our wanderings that our inclinations have not jumped in the same direction. I came of age a few months ago, and, in future, I can do as I please. Not that I have ever done anything else," she conceded, with another laugh, "because Aubrey's ways have been my ways until now."
"But for the sake of one month! What difference could it make to him?" he asked in astonishment.
"That's Aubrey," replied Miss Mayo drily.
"It isn't safe," persisted Arbuthnot.
She flicked the ash from her cigarette carelessly. "I don't agree with you. I don't know why everybody is making such a fuss about it. Plenty of other women have travelled in much wilder country than this desert."
He looked at her curiously. She seemed to be totally unaware that it was her youth and her beauty that made all the danger of the expedition. He fell back on the easier excuse.
"There seems to be unrest amongst some of the tribes. There have been a lot of rumours lately," he said seriously.
She made a little movement of impatience. "Oh, that's what they always tell you when they want to put obstacles in your way. The authorities have already dangled that bogey in front of me. I asked for facts and they only gave me generalities. I asked definitely if they had any power to stop me. They said they had not, but strongly advised me not to make the attempt. I said I should go, unless the French Government arrested me. … Why not? I am not afraid. I don't admit that there is anything to be afraid of. I don't believe a word about the tribes being restless. Arabs are always moving about, aren't they? I have an excellent caravan leader, whom even the authorities vouch for, and I shall be armed. I am perfectly able to take care of myself. I can shoot straight and I am used to camping. Besides, I have given my word to Aubrey to be in Oran in a month, and I can't get very far away in that time."
There was an obstinate ring in her voice, and when she stopped speaking he sat silent, consumed with anxiety, obsessed with the loveliness of her, and tormented with the desire to tell her so. Then he turned to her suddenly, and his face was very white. "Miss Mayo—Diana—put off this trip only for a little, and give me the right to go with you. I love you. I want you for my wife more than anything on earth. I shan't always be a penniless subaltern. One of these days I shall be able to give you a position that is worthy of you; no, nothing could be that, but one at least that I am not ashamed to offer to you. We've been very
