The girl's face faded out and that of Sir Winton Brett-Homes faded in. The heavy-set, heavy-faced Englishman looked down, obviously checking something on his desk. He looked up again, said, "Rex Donaldson?"

"Yes, sir."

"I won't waste time on preliminaries, Donaldson. We've been discussing, here, some of the disconcerting rumors coming out of your section. Are you acquainted with this figure, El Hassan?"

The black man's eyes widened. He said, cautiously, "I have heard a good many stories and rumors."

"Yes, of course. They have been filtering into this office for more than a year. But thus far little that could be considered concrete has developed."

Rex Donaldson held his peace, waited for the other to go on.

Sir Winton said impatiently, "Actually, we are still dealing with rumors, but they are beginning to shape up. Evidently, this El Hassan has finally begun to move."

"Ahhh," the wiry little field man breathed.

The florid faced Englishman said, "As we understand it, he wishes to cut across tribal, national and geographic divisions in all North Africa, wishes to unite the whole area from Sudan to the Mediterranean."

"Yes," Donaldson nodded. "That seems to be his program."
