This book is from the 1970's I believe. A priest lets an ill prostitute move in with him so he can care for her. Her name is Ursula Vaclav. One day the priest returns home soaking wet during a thunderstorm, and the prostitute runs and clings to him because she is terrified of thunderstorms. She then goes about making dinner while he goes to change into dry clothes, selecting a work shirt and pants rather than his priest outfit. He can't stop thinking about her as they drink wine with dinner, and he helps her with washing the dishes. As she puts the last dish away in the cupboard she turns toward him and he takes her in his arms and kisses her. He had never kissed a woman before, and then carries her up the stairs for more. I recall the title of the book as something like "the time and the hour", and I think the author was a man.
