Intelligence first. The intelligent novel-reader, unlike the inquisitive one who just runs his eye over a new fact, mentally picks it up. He sees it from two points of view: isolated, and related to the other facts that he has read on previous pages. Probably he does not understand it, but he does not expect to do so yet awhile. The facts in a highly organized novel (like The Egoist ) are often of the nature of cross-correspondences and the ideal spectator cannot expect to view them properly until he is sitting up on a hill at the end. This element of surprise or mystery—the detective element as it is sometimes rather emptily called—is of great importance in a plot. It occurs through a suspension of the time-sequence; a mystery is a pocket in time, and it occurs crudely, as in “Why did the queen die?” and more subtly in half-explained gestures and words, the true meaning of which only dawns pages ahead. Mystery is essential to a plot, and cannot be appreciated without intelligence. To the curious it is just another “and then—” To appreciate a mystery, part of the mind must be left behind, brooding, while the other part goes marching on.
That brings us to our second qualification: memory.
Memory and intelligence are closely connected, for unless we remember we cannot understand. If by the time the queen dies we have forgotten the existence of the king we shall never make out what killed her. The plot-maker expects us to remember, we expect him to leave no loose ends. Every action or word 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
