The sentence from the text that embodies the theme is, “Tell the truth or tell a lie, that was the question that always remained” (Grisham 131).  Luke faces a huge controversy in this story on when to tell the truth or not.  He keeps many secrets including what really happened in the fight behind the Co-Op, spying on Tally, and witnessing Cowboy murder Hank.  For a young boy, the truth may be hard to tell sometimes.  He does not want to incriminate himself or get himself into trouble either.  The results of telling the truth weigh heavily in Luke’s mind, until he finds enough to courage to tell what really happened.  Luke learned that the truth will set you free.
