He had some calls to make, and he was not altogether sure.

I left him in a few minutes and descended to the street.

I turned westward and walked for some little distance, when suddenly I was attracted by the sight of a familiar figure issuing from the door of a large, gray stone house.

We came face to face upon the pavement.

It was the man whose life I had probably saved only a few hours ago.
He lifted his hat, and his dark eyes sought mine interrogatively.
"You were not, by chance, on the way to call upon me ?" he asked.
I shook my head.
"Not only," I answered, "was I ignorant of where you lived, but I do not even know your name." "Both matters," he remarked quietly, "are unimportant." I glanced at the house from which he had issued.
"It would seem," I remarked, "that you have diplomatic connections." "Why not ?" he answered.
