For the character of Little Nell, the beautiful child thrown into a shadowy, terrifying world, Dickens drew on a tragedy in his own life, the death at the age of seventeen of his sister-in-law Mary Hogarth. Five years later he wrote, 'the desire to be buried next her is as strong upon me now ... and I know (for I don't think there ever was love like that I bear her) that it will never diminish.'
