Descriptions of Calpurnia, Dill, and Boo?

Dill (Charles Baker Harris)

A friend of the Finch children, who is a little older than Scout, quite short for his age, has an active imagination, and exhibits a strong sense of adventure. He initiates the first expeditions toward the Radley house, and is Scout's best friend. His family life is less than ideal, and he tends to resort to escapism when confronted with difficult situations. Dill spends summers with his aunt, who lives next door to the Finch family.

Boo Radley

A recluse who never emerges from his house. As a young boy, he was in trouble with the police, and his strictly religious and reclusive parents have kept him indoors ever since. A prisoner in his home, he stabbed his father with scissors once, and no one has seen him since. The town has developed a myth that he is an insane monster who wanders around at night peering into people's windows. Throughout the book, he lives with his brother, who is highly controlling.

Calpurnia

A black woman who works as the Finch family's cook and housekeeper. She is one of the many motherly figures in Scout's life and one of the few who can negotiate between the very separate black and white worlds of Maycomb.
