And the cause was this; she, of course, had been Halima's chief attendant in her illness, and, during her ramblings, her young mistress had disclosed the fact of her betrayal and, in consequence, her deep sense of injury and desire for vengeance; but with no mention of the name of her seducer.

The nurse being unaware that Halima knew Buonaparte, thereupon jumped to the conclusion that St. Just was the man who had robbed her former nurseling of her virtue, having assailed her in a moment when she was off her guard; that the intimacy once begun, Halima had been unable to free herself from her relations with her betrayer, and had thus lapsed to the position of his mistress, a toy he could discard when weary of it. The statement that they were really married with Mahometan rites the old woman regarded as a mere blind to cover Halima's dishonor. The thought worked her into a state of rage and hatred that was uncontrollable, and she resolved to punish the unsuspecting Frenchman, if by any means it could be done.

The course of events now seemed to have brought about her opportunity. The existence of the treasure was known throughout the camp, and it was rumored that it was to be sent to Cairo. When, therefore, the old woman heard that a messenger was to be despatched thither, she guessed what was his errand and laid her plans accordingly. Everything seemed to favor them, for the man selected for the mission was one of those most devoted to the late sheik's nephew, Yusuf, and withal one who deeply resented St. Just's position in the tribe. Naturally, St. Just was not aware of this, or another man would have been chosen. Yusuf had always been a favorite with the nurse; she had been present at his birth and had seen him grow to manhood, and had looked forward to seeing him eventually assume the headship of the tribe; thus his banishment by the old sheik had sorely troubled her. She now saw a chance of his reinstatement.

There were those in Cairo who would know his whereabouts. Accordingly, she sought the messenger who was to go to Cairo and who, it happened, was akin to her, and could be trusted not to betray her confidence, and instructed him to seek out Yusuf, and, should he find him, to tell him of the coming treasure; that, if he could collect a sufficient force and keep a good look out, he would be able to intercept it, and at the same time kill St. Just, who would be with it. That accomplished, there would be nothing to prevent his taking the leadership of the tribe, and making Halima his wife, should he desire it.

Should St. Just's messenger be unable to get speech of Yusuf, he was to forward her instructions to him by some one he could trust. The old woman was satisfied that, if Yusuf lived, he could be found, for many knew him; he had held an important position in the tribe and had many influential friends in Cairo.

She had no doubt that Yusuf would act upon her information, should it arrive in time; her only fear was that it might not reach him until St. Just should have advanced so far on his journey with the treasure, as to preclude Yusuf from making his arrangements for attacking him. However, that, as she piously observed, would be as Allah willed.

In due course, St. Just's messenger returned with letters from his Cairo correspondents. They had expressed delight at hearing of the treasure, and requested him to bring it on at once.

It was now February in the year 1800, and nothing stood in the way of St. Just's making an immediate start. To tell the truth, he was becoming somewhat wearied with desert life, and ready to welcome almost anything that would vary its monotony. So he set about at once to make his preparations. They were simple, including only a sufficiency of camels to transport the treasure, the devising of a ready mode of securing it on their backs, and the selection of the men to tend them; also supplies for the men's consumption by the way. The camels would need no food, for they would be required only to take the treasure to the river bank. St. Just had decided to make the whole journey by the Nile. It would take somewhat longer than by the desert route, but he preferred it as being less tedious and much more interesting. His point of debarkation would be a village five days' journey from Cairo; St. Just had halted there before, and was acquainted with a sheik who was friendly to the tribe and would, he hoped, supply him with camels for the remaining portion of the route.

It was agreed between himself and Halima—for she held firmly to her resolution to proceed to France—that, when he should have transacted the business connected with the treasure, he should write to her, by the returning party, stating where he would await her. Having regard to the condition of the country and the risk he ran of recognition, both felt that, at this stage, no definite fixture for their meeting could be made.

When everything was ready and the moment of departure had arrived, Halima, who thought she had schooled herself to the separation, broke down altogether. She threw her arms about his neck and clung to him with desperation, almost devouring him with kisses.
