"Yes, yes, Suleyman!—one that he, when he banish all the tribe of the demons from earth—one that he not found."

"One he overlooked?" jerked Sime.

"Yes, yes, overlook! A very evil man, my gentlemen. They tell me he has come to Egypt. He come not from the sea, but across the great desert—"

"The Libyan Desert?" suggested Sime.

The man shook, his head, seeking for words.

"The Arabian Desert?"

"No, no! Away beyond, far up in Africa"—he waved his long arms dramatically—"far, far up beyond the Sûdan."

"The Sahara Desert?" proposed Sime.

"Yes, yes! it is Sahara Desert!—come across the Sahara Desert, and is come to Khartûm."
