What play is being referenced in this scene from Chapter 31?
It made me shiver. And I about made up my mind to pray; and see if I couldn't try to quit being the kind of a boy I was, and be better. So I kneeled down. But the words wouldn't come. Why wouldn't they? It warn't no use to try and hide it from Him. Nor from me, neither. I knowed very well why they wouldn't come. It was because my heart warn't right; it was because I warn't square; it was because I was playing double. I was letting on to give up sin, but away inside of me I was holding on to the biggest one of all. I was trying to make my mouth say I would do the right thing and the clean thing, and go and write to that nigger's owner and tell where he was; but deep down in me I knowed it was a lie-and He knowed it. You can't pray a lie- I found that out.
