Charles Baker "Dill" Harris is the pint-sized member of the child threesome that also includes Jem and Scout. Dill hails from Meridian, Mississippi but comes to spend each summer in Maycomb with his Aunt Rachel, the Finches' neighbor. It is Dill who spurs the children's interest in Boo Radley, and he quickly becomes Jem's best friend--and, later, Scout's "permanent fiance." Dill is involved in most of the children's summertime adventures, boldly following Jem's lead; and, when Jem is not looking, he sneaks kisses from Scout, who clearly has fallen for her little friend.
With him, life was routine; without him, life was unbearable. (Scout, Chapter 12)
Dill is based on author Harper Lee's own summertime neighbor and lifelong friend--the late writer Truman Capote.
