A piece on Christianity in contemporary fiction in last week’s New York Times Book Review mentioned Flannery O’Connor’s “Parker’s Back” and subsequently sent me to my bookcase. I pulled Ms O’Connor’s Complete Works from the shelf, checked the index, and marked the story with the book’s ribbon. My apartment is small enough and the books organized well enough that the entire process took less than one minute. To read it took a good deal longer, not least because I have learned to read slowly but mostly because “Parker’s Back” is a frightening story about a man whose apparently misplaced faith yields cyclical resentment and crisis. Mr Parker’s judgment is not what we generally think of as “sound.” It’s an extraordinarily dense work, covers a great deal of time and space in fewer than 20 pages.
