When we were about half-way through, I suddenly put my hand upon her arm, for I had heard in the silent frosty air a sound that brought my heart into my mouth--the tap-tapping of the blind man’s stick upon the frozen road. It drew nearer and nearer, while we sat holding our breath. Then it struck sharp on the inn door, and then we could hear the handle being turned and the bolt rattling as the wretched being tried to enter; and then there was a long time of silence both within and without. At last the tapping recommenced, and, to our indescribable joy and gratitude, died slowly away again until it ceased to be heard.
