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. "Indeed," he continued thoughtfully, "I do not see, Captain Rotherby, why my name should remain a secret to you."

He drew a card from his pocket, and handed it to me. I read it with ill-concealed curiosity.
