Boo

Scout took Boo along with us and we peeked in the window of the dark house at the end of the street and saw Miss Harper Lee at a desk under the orange light of a solitary lamp writing her book.
Then Scout motioned for us to move away from the window, scolding us like Boo and I were sneaking past a watchman, and that it was none of our business. She said if we disturbed Miss Harper Lee while she was busy writing that it would be just like killing a mockingbird.
