Harry Potter almost met his end early, and unintentionally.
Think about all the crushed devil-worshipping children the world over who would have lost at least two night's sleep without knowing the fate of their adolescent hero. They'd have been tossing and turning never knowing if Ron ever got out of the carbonite he was left trapped in at the end of book six, or if Gollum would ever really lead Indiana Jones to the magic skulls of Jacob and Esau.
You see, there was a strict ban against carry-on luggage in planes for a bit there, and that ban extended towards J.K. Rowling's only copy of Harry Potter book 7. J.K. Rowling was in the States with the Harry Potter manuscript (some of it was only handwritten), and she had to get it home, but she refused to part with the Harry Potter book for fear it'd fall into the wrong hands.
And the wrong hands it did fall into. Read excerpts from chapters 3-7 on the next page.
