Betsy Klein is summoned from her home in the United States to her father’s hospital bed in South Africa. Orphaned young, he had to struggle to become a doctor and to win the respect of his Boer patients. We first meet young Harold Klein on an excursion with his friends on the Ebb ’N Flow, a river to which he often returns. That is where he later teaches his little daughter to row, and finally, where he makes his last metaphoric passage.
