Read it through once

As for the methods of conveying a clear understanding of a character, they are many. The first and the easiest is to make it clear by reason of some mannerism or personal peculiarity, some trick of speech or of carriage. This is the worst--as may generally be said of the easiest way. Another easy method is to describe your character at length. This also is a bad, because a tedious, method. If, however, you read a page or two of any good writer, you will discover that he first makes a character intelligible by a few words, and then allows him to reveal himself in action and dialogue. On the other hand, nothing is more inartistic than to be constantly calling attention in a dialogue to a gesture or a look, to laughter or to tears. The situation generally requires no such explanation: in some well-known scenes which I could quote, there is not a single word to emphasise or explain the attitude, manner, and look of the speakers, yet they are as intelligible as if they were written down and described. That is the highest art which carries the reader along and makes him see, without being told, the changing expressions and the gestures of the speakers, and hear the varying tones of their voices. It is as if one should close one's eyes at the theatre, and yet continue to see the actors on the stage as well as hear their voices. The only writer who can do this is he who makes his characters intelligible from the very outset, causes them first to stand before the reader in clear outline, and then with every additional line brings out the figure, fills up the face, and makes his creatures grow from the simple outline more and more to the perfect and rounded figure.
