Youd should read 'great, small, things' by Jody Picoult- about a black midwife in the USA- and a white supremacist family.
It was given to me by a friend from Australia. She is a Cape coloured (Cape Town SA) - and came to study nursing int he UK in the 70s. When she returned to SA, during Apartheid- she could only work in hospitals for blacks or coloureds. She was relatively fair skinned and spoke perfect English with flat rp accent- with British training and qualifications.
She met a surgeon from a white hospital and he employed her, against the Law, to work in one of his clinics. She only worked in theatre, once the patients were under anesthetics
unbelievable.
