down yet. Are you better?"

"Thanks, I am perfectly well," said Denzil, with a careless air.
"I thought I would breakfast early in order to drive into Cairo
before the day gets too sultry."

"Into Cairo!" echoed the Doctor. "Why, aren't you going to stay
here a few days?"

"No, not exactly," answered Denzil, stirring his coffee quickly
and beginning to swallow it in large gulps. "I shall be back to-
night, though. I'm only going just to see my sister and tell her
to prepare for our journey home. I shan't be absent more than a
few hours."

"I thought you might possibly like to go a little further up the
Nile?" suggested the Doctor.

"Oh, no, I've had enough of it! You see, when a man proposes to a
woman and gets refused, he can't keep on dangling round that woman
as if he thought it possible she might change her mind." And he
forced a smile. "I've got an appointment with Gervase to-morrow
morning, and I must come back to-night in order to keep it--but
after that I'm off."

"An appointment with Gervase?" repeated the Doctor, slowly. "What
sort of an appointment?"

Denzil avoided his keen look.
