From The Land in Winter by Andrew Miller:
At the edge of the field, by the shadow-line of the hedge, a dog, or something like a dog, raised its head into the light, studied them a moment, the two women upright in the bareness of the field, then dropped out of sight again, soundlessly.
This sentence ends a chapter. The dog, or something like a dog, doesn’t reappear. It adds menace and tension to the novel, partly because of the situation (two pregnant women in a cold, snow-covered field), but also because of the word choices Miller has made. “Edge,” “shadow,” “into the light,” “studied,” “bareness,” “out of sight,” and “soundlessly,” for example. Most of all, the point of view allows readers to know something that might be scary that the characters do not.
Two exercises, then. First, can we use the same words Miller does to create the opposite feeling for readers? We might allow ourselves to add words or see if we can change only their order. How are things different if the women watch the dog, for example? Second, how might we use the technique Miller uses? In other words, what can we let readers know that characters do not? How might this alarm readers, or how might it please them?
