When Mrs. Radley dies, Atticus goes to the Radley home, no doubt to pay his respects and offer assistance--a decent, neighborly thing to do. When he returns, he tells Jem and Scout that Mrs. Radley died of natural causes, which surprises and disappoints them. They were convinced that "Boo had got her at last." At Jem's urging, Scout finally asks Atticus if he had seen Boo while inside the Radley house. Her father's response makes it clear he does not wish to discuss his visit further:
Atticus looked sternly around his newspaper at me: "I did not."
Jem keeps Scout from asking any more questions, knowing that Atticus continues to disapprove of their obsession with Boo Radley. Scout has to be "restrained" from peppering her father with questions about what he saw inside the Radley house because he had just returned from behind "enemy lines" and could report what she and Jem could only imagine. Because pursuing the truth about the Radley home and its inhabitants was forbidden by Atticus, the children's fascination was only heightened. Scout tries to get information from her father, even though he has made himself clear on the subject, just as she had tried to get information about the Radleys from Miss Maudie.
