There was only one mystery Agatha Christie could not solve: her own.

Dame Agatha Christie is best known for her detective novels and short stories. She is one of the most popular authors of all time, her novels having sold over four billion copies and having been translated into 103 languages.

On the evening of December 8, 1926, Agatha Christie disappeared from her home in Sunningdale, Berkshire, leaving only a note for her secretary indicating that she was going to Yorkshire. Despite a massive manhunt, she was not found for eleven days. On December 19, 1926, Agatha was identified as a guest at a hotel in Harrogate, Yorkshire, where she was registered as Mrs. Teresa Neele of Cape Town. Christie would give no account of her actions. Why did she disappear?

Seven decades after her disappearance, the New York Times called Agatha Christie Harrogate's "most famous nonresident." The mystery of her unexplained disappearance has never ceased to fascinate Christie fans and time has not diminished their desire to find a solution. In this psychological novel, Dr. Carole Owens, a practicing psychotherapist, takes on Agatha Christie as a patient to diagnose her problem and at long last solve the mystery of Christie's lost days.
