Storyline
In 1930, the Crawleys, minus Mary, attend a London play starring Guy Dexter and Noël Coward. Backstage they meet with Guy, Coward, and former Downton butler, Thomas Barrow, now Guy's assistant and partner-lover. The next day, the Crawley family is attending Lady Petersfield's social event when news breaks about Mary and Henry Talbot's divorce; a disgraced Mary must immediately leave because royals are present. Robert and Cora return to Downton Abbey while Mary remains at Grantham House to receive Cora's brother, Harold Levinson, who is arriving from America following their mother Martha's death. Accompanying Harold is financial advisor Gus Sambrook, who saved Harold from financial ruin by withdrawing his investments in the stock market prior to the Wall Street Crash. Gus and Mary are mutually attracted and sleep together. The party travels to Downton Abbey, where Harold, to Cora's dismay, reveals that he squandered their mother's fortune on poor investments. He wants to invest Downton's remaining assets to recoup his losses and repay his debt to Gus.
News of Mary's divorce causes Downton neighbours to shun the Crawleys and refuse a dinner invitation. Robert, still reeling from Mary's failed marriage and Harold's delinquency, furiously walks out when Mary proposes selling the London Grantham House to raise capital. Mary leads her family in rejecting Gus' proposal to invest Downton's income, prompting Gus to blackmail Mary over their fling. Meanwhile, family member Tom Branson arrives and, along with Bertie Pelham, convinces Robert that Mary is doing what is best for the estate. Robert agrees and fully entrusts Downton Abbey to her, while he and Cora resolve to move to the Downton Dower house, taking along servants Bates and Anna.
At the Ascot Racecourse, an acquaintance informs Tom that Gus is a confidence trickster who became rich by swindling other people's fortunes. Deducing that Gus embezzled the Levinson wealth, Tom warns the Crawleys and Harold. Edith confronts Gus and forces him to back off from the Crawleys. As Gus leaves, he has a final encounter with Mary, who tersely dismisses him. A remorseful Harold reconciles with Cora before returning to America.
Edith and Cora learn that Guy, Coward, and Barrow are visiting Downton Abbey. Seeing an opportunity to rehabilitate Mary's reputation, they ask the servants to spread the news in the village. hoping to sway their neighbours. Mr Molesley, working full-time as a screenwriter, returns as a footman for the dinner, hoping Guy and Coward will notice him. Molesley is disappointed when Guy fails to remember him, though Coward is impressed that Molesley wrote the script for The Gambler. Molesley's spirits are further lifted after his conversation with Coward inadvertently provides the title for Coward's upcoming play, Private Lives, which is inspired by Mary's divorce. The dinner is a success, and the Crawleys are again viewed favourably.
Later, Lady Isobel Merton helps organise the annual county fair, where she clashes with the traditionalist chairman, Sir Hector Moreland, over how to run the event. Seeking fresh perspectives, Isobel invites Downton servants Daisy and Mr Carson to join the committee. They prove influential in supporting Isobel's ideas. When Sir Hector vehemently opposes having Mary present the fair's main award, Isobel organises a coup that ousts him as chair. Mary presents the award to Mr Mason, Daisy's father-in-law.
Robert and Cora complete preparations to move into the Dower house as they, the servants, and Edith express their confidence and trust in Mary's ability to manage Downton Abbey.
