C’est impossible! Poirot thought to himself. My little gray cells deceive me! I am sure that Agatha Christie passed away in 1976, and yet the evidence suggests otherwise. Perhaps she did not? No, sorry, she did, but her estate has authorized a brand-new Hercule Poirot novel anyway. The book will be written by Sophie Hannah, a British mystery novelist, and will be released in September 2014. Great! Now can we get a movie, too?
