“I did not see you.”

“Very likely, but I was there none the less.”

“Do you know me?” said the stranger; and Sir Norman could see he was gazing at him sharply from under the shadow of his slouched hat.

“I have not that honor, but I hope to do so before we part.”

“It was quite dark when you saw me on the bridge—how comes it, then, that you recollect me so well?”
