Bookstores are taking extraordinary precautions to keep Prince Harry's explosive memoir under wraps. "Spare" is already No. 1 on the Amazon best-sellers list, with interest fueled by his high-profile interviews promoting the book.

Prince Harry also spoke about the bombshell moment when Meghan Markle claimed members of the royal family wondered about Archie's skin color during an interview with Oprah Winfrey.
