“Listen, Sheikh,” he said, “you have made our hearts glad within us. For when this news came to England I said to myself that I would seek my old Arab friend and ask him to help me to find our young brother.”

“It is good,” said the Arab softly. “You remembered the far away.”

“How could I forget the man who watched by me in his tent when I was sick unto death, and who rejoiced over me when I was brought back to life? I looked back upon you as a brother and friend, and now I have come; but this must not be only a work of friendship. You and your young men must be paid, and paid well, for all their risks, for we do not come as poor suppliants. I and my friends are fairly rich, and will gladly spend money over this adventure.”

“Yes, money is as water that we fling upon the sand at such a time as this,” said the Sheikh. “And you are rich. Well, so are we. Our life is simple; we live as we have always lived, in tents, and our riches are in our flocks and herds, our camels and our horses. We have our pride as you have, even if we do work for the rich English for the piastres they pay. But in such a work as this for our wise brother and friend, take money? No; we go to help our brother. It is for love.”

“But Sheikh—” began Frank.

“Let your young brother be silent, Excellency; the bargain is made, and we must have much thought about how this is to be done. As you said, the fight must be with cunning; much wisdom must be brought to bear. We must try and find out what the Khalifa desires most. We must go as merchants, and you will need your piastres to buy enough for a little caravan of such things as will be welcome in the enemy’s camp. Powder for the guns of his people for certain he will want. Strong wines and waters too, for he, like those of his kind, loves to break the prophet’s laws. I will leave you now to sleep and muse upon all this. Mayhap you will find some plan or scheme, as you English call it, that will be better than mine; but something of this sort it must be, and we will go.”

“Yes,” said Frank eagerly, “and we will go.”

The Sheikh shook his head slowly.

“No,” he said, “this is no work for such as you. The task is for me and mine. Good-night.”

He turned, and seemed to fade into the darkness at once, just as the doctor, who had been waiting impatiently upon the seat, strode up.
