But the happiness of ministering to him passed very swiftly. As he grew stronger he managed so that she was rarely alone with him, and he insisted on her riding twice every day, sometimes with Saint Hubert, sometimes with Henri, coolly avowing a preference for his own society or that of Gaston, who was beginning to get about again. Later, too, he was much occupied with headmen who came in from the different camps, and as the days passed she found herself more and more excluded from the intimacy that had been so precious. She was thrown much into the society of Raoul de Saint Hubert. All that they had gone through together had drawn them very closely to each other, and Diana often wondered what her girlhood would have been like if it had been spent under his guardianship instead of that of Sir Aubrey Mayo. The sisterly affection she had never given her own brother she gave to him, and, with the firm hold over himself that he had never again slackened, the Vicomte accepted the role of elder brother which she unconsciously imposed on him. It was hard work sometimes, and there were days when he dreaded the daily rides, when the strain seemed almost more than he could bear, and he began to make tentative suggestions about resuming his wanderings, but always the Sheik pressed him to stay. Ahmed Ben Hassan's final recovery was quick, and the camp soon settled down into normal conditions. The reinforcements were gone back to the different camps from which they had been drawn. There was no further need of them. Ibraheim Omair's tribe, with their leader dead, had broken up and scattered far to the south; there was no chief to keep them together and no headman strong enough to draw them round a new chieftain, for Ibraheim had allowed no member of his tribe to attain any degree of wealth or power that might prove him a rival; so they had split up into numerous small bands lacking cohesion. In fulfilling the vow made to his predecessor Ahmed Ben Hassan had cleared the desert of a menace that had hung over it for many years. The relations between the Sheik and Saint Hubert had gone back to what they had been the night of Raoul's arrival, before his candid criticism had roused the Sheik's temper and fired his jealousy. The recollection of the miserable week that had preceded the raid had been wiped out in all that had followed it. No shadow could ever come between them again since Raoul had voluntarily stood on one side and sacrificed his own chance of happiness for his friend's.
