What does Shortning learn about honesty during his quest to free his father in the novel, Mississippi Chariot?

In planning his father's escape, Shortning tricks an FBI agent into entering Sleepy Corners and talking with the sheriff. He uses the informal rumor mill to his advantage, and thus, he effects the release of his father.

It is important to note, however, that Shortning feels guilt, and he questions his own morality as he sets up the trick. When it works, he continues to question his motives. Through a series of significant events, he realizes that sometimes correcting an injustice cannot be done without breaking rules, especially if a person is dealing with dishonest people. The novel does not endorse trickery or lying, though it does explore the intricacies of moral issues as they surface in an immoral situation.
