As soon as they were gone Mrs. Shiffney put on a fur coat, summoned an Arab called Amor, who had already spoken to her at the door of the hotel, and said to him:

"The one who takes Aloui as guide?"

"Where does he go at night? He's a friend of mine. I should like to meet him."

"He might be with Said Hitani."

"Where is that?"

"If madame does not mind a little walk—"

"Take me there. Is it far?"
