New theory on Dame Agatha's disappearance.
Well, probably not a totally new theory -- but one that is new to me:
But Norman, a former doctor, believes the novelist was in a fugue state, or, more technically, a psychogenic trance, a rare, deluded condition brought on by trauma or depression, which may also have led the writer and actor Stephen Fry to travel to Bruges in 1995 without leaving word with his friends or family.
'This kind of fugue state, which is much better understood these days, fits the symptoms that Christie showed during her stay in Harrogate,' said Norman.
My favorite theory is still the she-went-into-hiding-to-mess-with-her-adulterous-husband's-plans theory, but that's just because I find the idea of Devious Dame Agatha to be so very attractive.
