Who’s Talking? – Viewpoint and Voice

Using multiple narrators allows for pleasing contrast, if you achieve compelling variations in tone of voice, while differing interpretations of events will help to increase the sense of mystery and develop the plot.

Finding your voice doesn’t mean that you should force-feed readers your own opinions. People don’t read crime novels in the hope of being preached at. They are, however, often interested in engaging fiction written with attitude.
