Smiling indulgently, he lit a cigarette, and rehearsed the events that had led to such a happy conclusion.

He had known Lucy for several years, but only as a commonplace girl who happened to be musical. He could still remember his depression that afternoon at Rome, when she and her terrible cousin fell on him out of the blue, and demanded to be taken to St. Peter’s. That day she had seemed a typical tourist—shrill, crude, and gaunt with travel. But Italy worked some marvel in her. It gave her light, and—which he held more precious—it gave her shadow. Soon he detected in her a wonderful reticence. She was like a woman of Leonardo da Vinci’s, whom we love not so much for herself as for the things that she will not tell us. The things are assuredly not of this life; no woman of Leonardo’s could have anything so vulgar as a “story.” She did develop most wonderfully day by day.
