If, for most of the past in most parts of the world, most women have been 'hidden from history', black women in South Africa have been doubly hidden, both as women and because they are black. Three women - two of them black - meet in the pages of this title. Lily Moya was a Transkei schoolgirl growing up in lonely and alien surroundings. She sought help with her education from Mabel Palmer, an elderly white academic, then Organiser of the Natal University College's Non-European section. The third was Subusisiwe Makhanya, a remarkable Zulu woman and a pioneer social worker. Their letters illuminate more of the South African condition than the majority of history textbooks; the generosities, yet humiliations, of white liberalism; the nature of mission education; the socialisation of black girls; and the dilemmas they confront. They also reveal the separate worlds which we all inhabit, but which are made more frightening and more separate by the divisions of age, ethnicity and race.
