e is in trouble enough now; let us hope it will
be a lesson to him."

"No fear," exclaimed Charlie, with a hard look on his boyish face.
"Nothing will ever be a lesson to him; villainy was born in him, and
if ever he escapes, mark my word, the authorities will hear of him
again, or I am much mistaken."

His tone of conviction impressed his companion, and he looked
sharply at him.

"Why, what do you think he will do--raise another rebellion?" he
asked, incredulously.

"Stranger things have happened. We shall see. I am going to walk
back to the city with you," he went on, as George rose to go. "A
little fresh air will do me good."

The two friends linked arms and strolled back to Cairo. The night
was deliciously cool, and each had much to talk about, going over
and over again through the many incidents that had occurred since
their arrival in Egypt. At last the citadel was reached, and George,

where they found Naoum waiting to receive them.

He greeted our hero with affection, and looked in surprise at
Charlie. Helmar was quick to interpret the glance, and hastened to
set his mind at rest.

"This is my greatest German friend, Naoum," he said, "and I brought
him with me that he might meet the man who has done so much for a
stranger in a strange land; his name is Charlie Osterberg."

Naoum acknowledged the introduction cordially, and begged them to
rest.

"I was surprised when Belbeis told me that you had returned to Cairo
again so quickly. Had I known it before, I should have sought you

things I would say to you, but time presses,
