On page 268, Lee writes:
"High above us in the darkness a solitary mocker poured out his repertoire in blissful unawareness of whose tree he sat in, plunging from the shrill kee, kee of the sunflower bird to the irascible qua-ack of a bluejay, to the sad lament of Poor Will, Poor Will."
In this first part of chapter 28, Ms. Lee is building the suspense of things to come. Scout and Jem are walking by the Radley place and are discussing, ghosts, spirits and scary things. Scout hears the lonely Mockingbird sing its song. This scene continues to remind the reader of Lee's motif of innocence and the mockingbird. We begin to realize that Scout still has a lesson to learn. Later in the chapter Scout, Jem, and Boo Radley will all lose more of the innocence they have had up to this point in the novel.
