“The reader tries to uncover the skeleton that the book conceals. The author starts with the skeleton and tries to cover it up. His aim is to conceal the skeleton artistically or, in other words, to put flesh on the bare bones. If he is a good writer, he does not bury a puny skeleton under a mass of fat; on the other hand, neither should the flesh be too thin, so that the bones show through. If the flesh is thick enough, and if the flabbiness is avoided, the joints will be detectable and the motion of the parts will reveal the articulation.”
