While there are quite a few characters present within Chapters 6 and 7, the bulk of the action centers around Jem, Scout, Dill, Mr. Nathan Radley, and a not-yet-named mystery character.

In Chapter 6, Jem, Scout, and Dill take their curiosity about the Radley place to a whole new level when they run onto the Radley property.  Nathan Radley responds by assuming that a prowler, or more accurately, a "Negro", is lurking and fires a shot in their general direction.  Jem, Scout, and Dill scurry, but Jem must leave his pants when they catch on the Radley fence.

In both chapters, we see a mysterious figure showing kindness to the Finch children.  The person mends Jem's pants after the incident mentioned above, and, likewise, begins to leave presents for the children in the knot of the tree that stands in front of the Radley house.  One conjectures that this figure is Boo, a thought strengthened by the fact that Nathan Radley, Boo's father, seems hell-bent to keep the kids and other visitors away from his property.  Nathan Radley even goes so far as to pour cement into the knot in the tree, preventing further exchanges of gifts.

Thus, one of the biggest characters in both chapters is not entirely known.  While the mystery person plays a large role, and while we posit that it might be Boo, we will not receive more concrete information until later in the text.
