Patricia Highsmith said this quote
“ I had depressing thoughts that the theme, even though I had thought of it, was better than I was as a writer. Henry James or Thomas Mann could easily write it, but not I. 'I'm thinking of writing it from the point of view of someone at the hotel who observes her,' I said, but this did not fill me with much hope. Then my friend, who is not a writer, suggested I try it from the omniscient author's point of view. ”
