How often I had looked at the lovely things as they rested for a moment on my dark coat sleeve when I was out in a snowstorm. And after seeing Rivers draw them so skilfully, several times, they had taken on a new interest to me. But what had so moved Zizi I could not imagine. It was as if the little drawing were fraught with some dreadful significance of which I knew nothing.

Nor was Pennington Wise any more aware than I of the girl’s meaning.

“Yes; to the limit.”
