Theory about Agatha Christie's most personal mystery [audio 4min]

Dr. Andrew Norman's new biography of whodunnit writer Agatha Christie offers a theory that may explain a mystery in Christie's own life. In 1926 she disappeared for 11 days before she was discovered at a hotel in Harrogate, England. Norman tells Andrea Seabrook Christie had experienced a"fugue state." His biography is Agatha Christie: The Finished Portrait (Tempus Publishing).
