“It’s not an easy question Miss Mayella, so I’ll try again. Do you remember him beating you about the face?” Atticus’s voice had lost its comfortableness; he was speaking in his arid, detached professional voice. “Do you remember him beating you about the face?”
“I don’t recollect if he hit me. I mean yes I do, he hit me.”
– Harper Lee
To Kill a Mockingbird, Chapter 18. When Atticus asks Mayella Ewell during cross-examination if she remembers Tom Robinson beating her, she stumbles with her answers, contradicting herself. This calls her account into question.
