Ross and Demelza Poldark have weathered the difficulties of their marital breach, and the result is that Demelza is again pregnant. The feud between Ross and George Warleggan has been in abeyance, but in this novel George shows that he is even more of a villain.
The difficulty begins with a friendship. George Warleggan thinks that Geoffrey Charles Poldark, his stepson, is spoiled from spending too much time with his mother. He wants to send Geoffrey Charles to school or failing that, get him a tutor, but he compromises with Elizabeth by allowing her to hire her cousin, Morwenna Chynoweth, as Geoffrey Charles’s governess. While Geoffrey Charles and Morwenna are out on the beach, they meet Drake Carne, one of two of Demelza’s brothers who have come to the area looking for work.
Although there is quite a distance in their stations, Drake being the son of a miner and Morwenna the daughter of a vicar, Drake and Morwenna’s friendship gradually turns to love. Morwenna has no idea that George has been plotting an advantageous marriage for her—at least one that allies him with an established family of the area.
In the meantime, others are interested in the news from France. Ross hears that Dwight Enys’s ship has been sunk after a naval battle. He goes to some trouble to find out if Dwight is alive, both for his own sake and that of Dwight’s fiancée, Caroline Penvenen. Eventually, Dwight’s plight leads Ross into an even more hazardous venture.
Some foreshadowing of future events, possibly, comes with the birth of George Warleggan’s son Valentine. He is born under a black moon (an eclipse), which the local people believe is an ill omen. And perhaps there are small indications that he will not be a normal child. I don’t know, but I am interested to find out.
