Agatha Christie

Well-known English writer Agatha Christie disappeared mysteriously for 11 days in 1926. Sir Arthur Conan Doyle even tried to find her by having a psychic read her glove. She was eventually found safe, but the mystery behind her disappearance was only solved 80 years later. In 2006 it was discovered that she was under the grip of a rare but increasingly acknowledged mental condition known as a ‘fugue state’, or a period of out-of-body amnesia induced by stress.
