A Lady Trader in the Transvaal presents the South African adventures of Sarah Heckford, a once famous but now forgotten Anglo-Irish gentlewoman. After treking to the Transvaal in 1878, this intrepid woman served as governess, doctor, builder, nurse, and farmer. When her farm failed, she broke through the barriers of gender and class to make her fortune as a smous or peddler —trading with the Africans and Afrikaners of the remote bush-veldt. Caught up in the Anglo-Boer War of 1879–1880, she survived the hundred-day siege of Pretoria only to find the British dishonored and herself financially ruined.
