Miranda had already heard enough from Wilbraham to confirm M. Fournier's statement about the custom-house.

"No," continued Fournier, "the risk is too great. And I call it risk!" He hunched his shoulders and spread out his hand. "It is a red-hot cert, as he would say. His identity would be established, and he had better, after all, be a captive in Morocco than a convict in England. There is some chance of an escape in Morocco."

"There is also in Morocco some chance of a--" Miranda's lips refused to speak the word. M. Fournier supplied it.

"Murder? I do not fear that. Had they intended murder, they would have killed that night, then and there, in the Sôk of Tangier. There would have been no letter dropped three days inland."

Miranda eagerly welcomed the argument. "Yes, yes," she exclaimed, and the colour came back to her lips. "He is held for ransom then, surely?"

M. Fournier shook his head. "Hardly. Had they captured him for ransom, they would have got from him the names of his friends. They would have used measures," said he, with some emphasis upon the word, at which Miranda shivered; "sure measures to get the names, and Warriner would have given mine. They would have come to me for the ransom, and I should have given it--if it was everything I had--and Warriner would be safe by now."

Fournier was aware that Miranda looked curiously and even with a sort of compunction towards him, though he did not understand the reason of her look. To him it was the most natural, simple thing in the world that he should care for Warriner.

"No, it is not ransom," and he threw a cautious glance this way and that, and then, even in that secret spot, continued in a whisper: "Warriner has enemies, enemies of his own race. I do not wonder at it," he explained impartially. "He treats me, yes, even me, who am his one friend, as though--well, his own phrase is the best. He wipes the floor with me. He has promised to do it many times, and many times he has done it too. No doubt he has enemies, and they have arranged his capture."

"Why?"

"Suppose they sell him for a slave, a long way off and a long way inland. It would not be pleasant at all, and most of all unpleasant to him, for he is particular. Of course you know that, Mrs. Warriner. He likes his linen very clean and fine. He would not enjoy being a slave, yet he could not appeal to his Government, even if he got the chance."
