Ross's Return and Shattered Hopes
Ross Poldark returns to Cornwall in 1783 after three years fighting in the American Revolutionary War. Many people thought he had died. He finds his family home, Nampara, in bad shape, managed by his two lazy and often drunken servants, Jud and Prudie Paynter. The copper mine on his land, Wheal Leisure, is flooded and not working. Worse, his childhood sweetheart, Elizabeth Chynoweth, is engaged to his cousin, Francis Poldark, because everyone believed Ross had died. Ross goes to the engagement ball, a painful event where he sees Elizabeth's new life and feels his family's pity and his own loss. This makes him determined to rebuild his life on his own.
Rebuilding Nampara and a Chance Encounter
Sad but determined, Ross begins the hard work of fixing Nampara. He works with his tenants, clearing land, repairing buildings, and trying to revive the neglected farm. During a trip to Redruth market, he steps into a brutal dogfight and saves a young, hungry girl named Demelza Carne from her abusive father and a violent crowd. On impulse, he offers her a job as a scullery maid at Nampara. Despite her rough background and messy appearance, Ross sees a spark of spirit in her. He brings her back to his damaged estate, surprising and upsetting his servants and the local gentry.
Demelza's Transformation and Growing Affection
Under Ross's care, Demelza slowly changes. He teaches her to read and write, and she learns how Nampara works, becoming an important part of his home. Her initial shyness turns into a lively personality, and her appearance gets much better, showing a striking beauty. Demelza becomes very loyal and develops a deep, unspoken love for Ross. Meanwhile, Ross, though still hurt by Elizabeth's marriage to Francis, starts to value Demelza's company and lively spirit, finding comfort and real affection in her presence, even as he struggles with the class differences and social rules that separate them.
The Wheal Leisure Venture and Social Strife
Wanting to provide for his tenants and challenge the established gentry, Ross decides to reopen his old mine, Wheal Leisure. He forms a company, offering shares to local people and even some of his tenants. This is a radical move that earns him both respect and suspicion. The venture involves financial risk, needing significant investment and hard work. Ross dedicates himself to the mine, actively working in its operations and showing real concern for his miners' well-being. This decision makes him a leader for the working class, setting him apart from his more traditional Poldark relatives and the powerful Warleggan family.
Francis's Downfall and Elizabeth's Unhappiness
Francis Poldark, Ross's cousin and Elizabeth's husband, is a weak man who is easily influenced. He gambles, drinks too much, and falls for the manipulative friendship of George Warleggan, which leads to big financial losses. His poor management of his own mine, Grambler, and his increasing debts strain his marriage to Elizabeth. Elizabeth, though happy at first, finds herself more and more alone and unhappy with Francis's behavior and their declining money. Ross watches their struggles, his pity for Elizabeth often clashing with his resentment towards Francis.
A Developing Relationship and Social Outrage
As Christmas gets closer, the unspoken affection between Ross and Demelza reaches a turning point. After a particularly difficult day, made worse by Ross's sadness over Elizabeth, Demelza tries to comfort him. Their shared vulnerability and deep emotional connection lead to a night of intimacy. Recognizing his responsibility and his real feelings for her, Ross makes the unusual decision to marry Demelza, despite her low social standing and the scandal it will cause. The news shocks Cornish society, especially the Poldark family and the gentry, who see it as a bad match.
Demelza's Introduction to Society
Demelza's move into the role of Mrs. Ross Poldark is hard. She faces immediate snobbery and disrespect from the local gentry, including Ross's aunt, Agatha, and even some of his well-meaning friends like Verity Poldark. Despite her natural grace and intelligence, Demelza knows she lacks formal education and refined manners. Ross, very protective, helps her navigate these social situations. With time, and especially after a good appearance at a local assembly where she charms many with her singing, Demelza starts to find her place, showing her strong character and winning over some of her critics.
The Birth of Julia and Growing Happiness
Despite the initial social disapproval, Ross and Demelza's marriage is strong and loving. Demelza becomes pregnant, and their happiness grows with the thought of their child. The birth of their daughter, Julia, brings great joy to Nampara and strengthens their bond. Ross, who once thought happiness was lost to him, finds deep contentment and love in his life with Demelza and their child. Their happy home life contrasts with the growing unhappiness and financial problems of Francis and Elizabeth at Trenwith, showing the success of Ross's choice.
Verity's Romance and Family Conflict
Ross supports his cousin Verity Poldark's long-delayed romance with Captain Andrew Blamey, a man her family deems unsuitable because of a past scandal. Despite the Poldark family's strong objections, especially from Francis and Charles, Ross helps them reunite and encourages Verity to follow her heart. This leads to Verity's elopement with Captain Blamey, a decision that further separates Ross from the Trenwith Poldarks, particularly Francis, who feels betrayed and shamed by Ross's involvement. The event shows Ross's independent spirit and his willingness to go against social rules for true affection.
The Illness and a Tragic Loss
A severe epidemic of putrid throat (diphtheria) spreads through Cornwall, devastating many families. Ross, with his usual compassion, visits his sick tenants and neighbors, offering help. Tragically, the illness reaches Nampara, striking down first Demelza, who gets it while nursing a sick child, and then their infant daughter, Julia. Despite Ross's desperate efforts and the doctor's best attempts, Julia dies from the illness. This devastating loss puts Ross and Demelza into deep grief, testing their bond and leaving a deep scar on their lives. The novel ends on a somber, but strong, note.
