Any one about to read this work of fiction might properly be apprised beforehand that it is not a novel: it has neither the structure nor the purpose of The Novel. It is a story. There are two characters - a middle-aged married couple living in a plain farmhouse; one point on the field of human nature is located; at that point one subject is treated; in the treatment one movement is directed toward one climax; no external event whatsoever is introduced; and the time is about forty hours.
