Now married, living on a sugar cane plantation, and working as a maid in Queensland, Meggie finds her new husband is more interested in his own work and dalliances than in her. She bears him a child but is still unable to change his ways. Meanwhile, Father de Bricassart has moved up in the Church hierarchy and eventually returns to Australia as a Cardinal. And in yet another uneasy reunion between himself and Meggie, he finally succumbs to temptation by consummating forbidden love and breaking his vow of chastity.
