Agatha Christie was the most popular mystery writer of her time. But in her novels, the mysteries were always neatly solved by beloved detectives who readers had come to know and trust. In Christie’s own life, however, there was no Miss Marple or Hercule Poirot. When she disappeared in 1926, the world thought she was dead. The police and other mystery writers, Dorothy Sayers included, were in the midst of investigating her murder and then…she reappeared. And for the rest of her life, the queen of crime never quite explained what had happened. The world’s greatest mystery writer took one secret to her grave:the enigma of her disappearance.
