The old house was the same, droopy and sick, but as we stared down the street we thought we saw an inside shutter move. Flick. A tiny, almost invisible movement, and the house was still.

– Harper Lee

To Kill a Mockingbird, Chapter 1. There is an ominous feel about the Radley house, with the small flicker of movement suggesting someone is watching from inside. The children are fascinated with Boo who never comes out of the house, but he is interested in them also. The scene foreshadows Boo’s entrance into the children’s lives.
