In what chapter of To Kill a Mockingbird do Jem and Scout realize that Boo Radley was the one who was putting stuff in the tree?Either a chapter number or a page number, please. Thanks!!
In my opinion this is a trick question. Jem begins to realize that it is truly Arthur Radley in Chapter 7; however, Scout doesn't begin to realize this until sometime later. For example, after finding so many treasures in the tree, Jem decides they should write a letter thanking the person doing so. At this point, Jem suspects. This is revealed right in the middle of Chapter 7:
[Jem] had been on the verge of telling me something all evening; his face would brighten and he would lean toward me, then he would change his mind. . . . "Okay. Dear Mister . . ."
"How do you know it's a man? I bet it's Miss Maudie--been bettin' that for a long time."
"Arr, Miss Maudie can't chew gum--" Jem broke into a grin. (Lee 61)
Jem, of course, is older than Scout and comes of age through To Kill a Mockingbird. Scout is somewhat younger and, even in Chapter 8, is shocked and somewhat dismayed that Arthur Radley had come up behind her to place a blanket over her shoulders. Therefore, because Jem is the first of the two to realize it is truly "Boo" Radley that placed the treasures in the tree (and that realization comes in Chapter 7), that is the true answer to your difficult question.
