“The n***** run off the very night Huck Finn was killed. So there’s a reward for him – three hundred dollars. And there’s a reward out for old Finn, too – two dollars.”

– Mark Twain

The Adventures of Huckleberry Finn, Chapter 11. The women are talking about Jim running away from the Widow’s home. But Huck keeps his mouth shut and says nothing about Jim’s escape.
