Describe a subplot (i.e., a secondary plot or minor conflict) in the novel.To Kill a Mockingbird by Harper Lee

While Boo Radley is an important character who figures
into the entire narrative of To Kill a Mockingbird, the subplot
that involves the superstitions of the children and their attempts to overcome them
figures in as a minor episodes. 

As Scout and Walter walk
home for dinner after school, she tells him "this is where a haint
lives."  Later, Dill dares Jem to do such things as run up to the Radley house and look
in the window and they are involved in play-acting in which they recreate the defining
scissor scene.

This subplot focuses on the games and tricks
that Dill, Jem and Scout engage in as they toy with the fear and excitement of
a "haint." 

One minor conflict that helps support the major
racial conflict is that of Mr. Dolphus Raymond, who has chosen to live with the blacks. 
In order to help the whites reconcile their feelings about this situation, Mr. Raymond
feigns alcoholism by carrying around a bottle of Coca-Cola wrapped in a brown paper bag
as one would wrap a bottle of beer or liquor.
