Answered Prayers

In May 1971, on The Dick Cavett Show, Capote referred to the book as his "posthumous novel", explaining, "either I'm going to kill it, or it's going to kill me".
The book is a somewhat sordid tale of the mixing of high and low social classes, drawn from his experiences as best friend and confidant to the most prominent female socialites of the era and their husbands. The first chapter of Answered Prayers, Unspoiled Monsters, which was published in Esquire, is largely based on Capote's friend, the real-life male prostitute Denham Fouts. Capote first envisioned it as an American analog to Marcel Proust's Remembrance of Things Past that would come to be regarded as his masterwork in the late 1950s.
