She nodded. “I can. I do. And why not? It’s what I’m here for.”

Her voice had a note of challenge. Her eyes had gone beyond him. They rested upon the wealth of purple flower that crowned the coping of the cloister-arch in the hot sunshine, and again they held that wistful look as of baffled longing for the unattainable.

He got what he angled for. She threw him a fleeting smile, and in a moment he caught the charm which up till then had eluded him.
