Nelson Mandela's former private assistant Zelda la Grange speaks at the launch of her book "Good Morning, Mr Mandela" in Johannesburg, June 19, 2014. La Grange's memoirs, published on Thursday, traces the 43-year-old's upbringing in an Afrikaans family that considered Mandela a terrorist. It goes on to describe her improbable appointment to his office when he became president in 1994, and her close relationship with him until his death last year.
