“Of course,” he answered, patting my shoulder. “Of course I have. What did you think I would be doing?”

“What was the matter with me?” I asked.

“Nothing much,” he said lightly, “a touch of the sun, and a great deal of overwork in behalf of your friends. Now keep still, or I will be getting peppered.”

I was silent for a while, turning over this answer in my mind. Then I said:—

“I had yellow fever.”

He started.

“It is no use to lie to you,” he replied; “you're too shrewd.”

I was silent again for a while.

“Nick,” I said, “you had no right to stay here. You have—other responsibilities now.”
