The Help discussion

Hi! A friend of mine posted a sentence but he can't Remember the name of the book and this Is drive me Crazy. Here Is the sentence: he was silent because there was no need to answer, he had no obligation to answer, he did not want to answer, and furthermore, It was a question with no answer. He knew It was underhanded of him to do this but he still offered his smile and said: let's go home it's too cold here".
I know It Is not much and i have already searched on Google books so i hope some of you have read It.
Thanks
