I'm giving this 2.5 stars. I imagine it could have been better had Capote bothered to finish it. According to the lore, Capote preferred to live as a celebrity than as a writer, having spent so much time resting on his In Cold Blood laurels.
Answered Prayers was designed to be a modern Remembrance of Things Past, but it comes off as crude and limp. PB Jones drifts through life, carried by society and sleazy jobs, and basically functions as the ear for people with lots of dirt to unload. The final story here is said to have killed his career and his standing in society. Lots there to make you go "mee-yow!"
