One day, I

"Every action or word in a plot ought to count; it ought to be economical and spare; even when complicated it should be organic and free from dead matter. It may be difficult or easy, it may and should contain mysteries, but it ought not to mislead. And over it, as it unfolds, will hover the memory of the reader (that dull glow of the mind of which intelligence is the bright advancing edge) and will constantly rearrange and reconsider, seeing new clues, new chains of cause and effect, and the final sense (if the plot has been a fine one) will not be of clues or chains, but of something aesthetically compact, something which might have been shown by the novelist straight away, only if he had shown it straight away it would never have become beautiful."
