One of the principal and most mysterious sub-stories in the novel happens to be Boo Radley. As children, Jem, Scout, and Dill always feared Boo, however they also developed a hunger for curiosity at the so-called phantom. The more events that unravel and the older the children become, the less time they have to try and lure Boo out of the house. At some points in the novel, it's almost like they forget about him completely. The Radley house becomes a normal house to pass in their daily routines and the children have other fears to worry them. The children are uncertain as to who leaves them gifts in the oak by the Radley property, nor are they certain of who placed a blanket on Scout when she was watching a house go up in flames, it seems as though a relationship between Boo and them begins to form as a result of Boo's appreciation for their infantile patience and curiosity. Towards the end of the novel, Boo Radley reveals himself when he saves the children from an attack committed by Bob Ewell. This shows that he had been keeping an eye on the children, likely watching out for them because he knows them; regardless of whether or not they knew him. After Dr. Reynolds and Sheriff Heck Tate leave the premises following the attack, Scout takes Boo Radley's hand, sits with him , offers him a seat, and walks him home. It appears the Scout, too is familiar with him. Her fear seems to be diminished now that she knows her discomfort was trapped between stories, not the reality that she witnessed.
