"Now, my good man," she said to Hammet Abou, in a language totally incomprehensible to him, "money is no object in this question, but what will you do with Monsieur de Sabron if you find him? He may be an invalid, and the ransom will be fabulous."

The Comtesse de la Maine felt the girl's arm in hers tremble. Hammet Abou answered none of these questions, for he did not understand them. He said quietly to Tremont:

"The caravan starts to-morrow at sundown and there is much to do."

Tremont stood pulling his mustache. He looked boyish and charming, withal serious beyond his usual habit. His eyes wandered over to the corner where the two women stood together.

"I intend to go with you, Hammet Abou," said he slowly, "if it can be arranged. Otherwise this expedition does not interest me."

Two women said:

"Oh, heavens!" at once.

Robert de Tremont heard the note of anxiety in the younger voice alone. He glanced at the Comtesse de la Maine.

"You are quite right, Madame," he said, "a man's life is at stake and we stand chaffing here. I know something of what the desert is and what the natives are. Sabron would be the first to go if it were a question of a brother officer."

The Marquise d'Esclignac got down from her throne, trembling. Her eyes were fixed upon her niece.
