Tuck Everlasting Theme of Lies and Deceit

Someone forgot to tell the Tucks that the truth will set you free. And so, in Tuck Everlasting, they're stuck, never able to admit to the rest of the world who they really are. They're living a lie—through and through—but can we blame them? (Really, we're asking.) After all, they're lying to protect other people. The entire world, actually. Who knows what kind of craziness would go down if everyone knew about the possibility for immortality? But all that doesn't change that they're lying—and asking Winnie to do the same.

1. Why are the Tucks so obsessed with keeping the spring a secret? How has keeping that secret changed their lives—for better and for worse?
2. What lies does Winnie tell throughout the novel? Are they white lies or big, fat, nasty lies?
3. Are the Tucks justified in lying to everyone they meet?

The lies that the man in the yellow suit tells are clearly the bad kind. The Tucks, on the other hand, are just lying to protect people.

By the end of the book, Winnie's been totally corrupted by the Tucks: she's willing to lie to her parents and the constable—break the law, even—in order to help Mae Tuck go free.
