Almost twenty years ago (1957) Alan Burgess told the story of another missionary -- in China -- The Small Woman. Helen Roseveare is really more exceptional -- apparently a very plain-faced woman whom God has endowed with a humility life would strengthen and a dedication second to none. Helen went from England to the Belgian Congo in 1953 where, helped by a young black, John, became a supremely skillful surgeon, and started a hospital in Nebobongo which in time would serve 48 rural clinics via pickup truck. She refused to be frightened away -- by the austerity of the tin can diet, by a mamba snake in her zinc bowl, by various illnesses, or by the increasingly charged political situation. Eventually, with others, she was the victim of the People's Liberation Army (rape, assault, imprisonment) but somehow she was handpicked for survival. Burgess tells her story with containment which does not exclude its considerable human interest and it is gratefully free of sugarlined cliches.
