What does the name "Agatha Christie" mean? For many, it's synonymous with a murder mystery book, a "whodunnit." People often say, "I'm reading an Agatha Christie," and then add, "I'm not sure who the murderer is—I think it's..." But they're usually wrong, because it's not easy to guess the murderer before the book ends. But who was Agatha Christie, really? What was she like as a person? Was her life quiet and unremarkable, or was it full of interest and adventure? Was there a hidden mystery in her life?
