Personal History--Not Mine

Just yesterday I was talking about The Postcard, in which a young boy discovers some clues to his late grandmother's life while cleaning out her home after her death. Today I read that Agatha Christie's grandson recently found tapes of her voice while cleaning out one of her former homes well after her death, which was back in 1975. Christie made the recordings in the 1960s while preparing material for her autobiography.

People learn new things about grandmas all the time.
