What is the author's style in Answered Prayers: The Unfinished Novel by Truman Capote?

The narrative is written from the first person and past tense point of view, which is specifically, that of the narrator, P.B. Jones. There are several points to note here. The first is that the book's narrative perspective, as is generally the case with most first-person narratives, is entirely subjective, with events, situations and characters described through the experiential and emotional filters of the narrator. In other words, the narrative is an interpretation as much as it is a recounting, said interpretation being defined by the specific prejudices and intentions associated with the person telling the story.
