How do the children plan to spend Dill's last night Maycomb?

The night before Dill goes back home, he and Jem decide to go on one last adventure. Jem hesitantly lets Scout join them. They deccide to spy on the Radley house. They want to spy on Boo Radley through the window, in hopes of catching a glimpse of this legendary figure. They enter through the creaking gate to the cottage, terrified they will be discovered. They quietly sneak around to the back of the house. Jem quietly creeps to the window and lifts himself up. It is then that Scout spots a shadow. At first, she thinks it is a tree. Then she sees it move:

The shadow stopped about a foot beyond Jem. Its arm came out from its side, dropped, and was still. Then it turned and moved back across Jem, walked along the porch and off the side of the house, returning as it had come (Chapter 6).

The children become aware of the human shadow and bolt from the yard. They escape under the barbed wire fence. Jem's pants catch on the barbed wire, so he leaves them behind. The shadow, who is Mr. Nathan Radley, fires a shot into the air.
