In this official and fully restored edition, Hercule Poirot solves his first case in the Agatha Christie novel that started it all, now featuring a "missing chapter" and exclusive content from the Queen of Mystery. "It's tempting to say that Agatha Christie is a genius and let it go at that, but the world's had plenty of geniuses. Agatha Christie is something special." - Lawrence Block, New York Times bestselling author
