At the end of chapter 27, what elements help create a mood or a feeling of apprehension?
As Jem and Scout are about to leave for the Halloween pageant, Aunt Alexandra has a strange intuition. She stops mid-sentence, opens her mouth, but does not say anything. When Scout asks her, "'s matter, Aunty?" She says, "Oh nothing, nothing . . . somebody just walked over my grave." She ignores this "pinprick of apprehension" and goes on as usual.
As Jem and Scout leave the house, Scout's narration also foreshadows that something bad is coming when she says, "Thus began our longest journey together." When they emerge from the pageant, Bob Ewell will be waiting for them.
