Love in a Cold Climate is a novel by Nancy Mitford, first published in 1949. The title is a phrase from George Orwell's novel Keep the Aspidistra Flying (1936).
 Love in a Cold Climate is a companion volume to The Pursuit of Love. The time frame of Love in a Cold Climate is the same as The Pursuit of Love, but the focus is on a different set of characters. Fanny remains the fictional narrator. In The Pursuit of Love, Fanny narrates the story of her cousin Linda Radlett. In Love in a Cold Climate, Fanny narrates the story of Polly, to whom Fanny is distantly related through her father's family.
 Lady Leopoldina "Polly" Hampton is the only child of the supremely aristocratic and very rich Earl of Montdore and his wife, Sonia. Lady Montdore is a product of the minor ranks of the aristocracy and her marriage to an earl is regarded as a social coup on her part. She is depicted by Fanny as an avaricious, greedy snob, but not without charm. Her thrusting personality, allied to her husband's impeccable social standing, riches and political influence makes her a formidable woman. Lady Montdore, unbeknownst to Lord Montdore, takes advantage of her husband's reputation to forward her own career as a hostess and manipulator of her social circle. Their daughter is Polly, whom Fanny loses contact with when Lord Montdore is sent as Viceroy of India.
 Fanny receives an invitation to visit the Montdores upon their return from India. She has great affection for Polly, but Polly reveals little of herself. Polly has "come out" in India and as a beautiful and socially important debutante is expected to have a very successful season in London. However, Polly consistently demonstrates a total lack of interest in the London season and all of the men she meets. She is hoping that "in a cold climate", society will be less interested in love affairs. Lady Montdore is exasperated by her daughter's apparent indifference to love and marriage. "Important" potential suitors acknowledge that Polly is very beautiful, but find her cold and aloof. Polly reveals to no one that she has been in love with her uncle, "Boy" Dougdale (the husband of her paternal aunt), since she was 14. Boy is snobbish and sexually rapacious; his many affairs are common knowledge to both his wife and society at large. Fanny and her Radlett cousins have long suspected that the sexually ambiguous Boy has paedophilic tendencies, and he is a joke amongst Fanny's cousins for his inappropriate touches and "lecherous" behaviour towards young girls. Polly marries Boy shortly after her aunt's death, causing a scandal in her social circle and distressing her parents deeply. Unbeknownst to Polly, Boy has been Lady Montdore's lover for many years. She is excluded from her father's will upon her marriage and she and Boy ostracised from society. They move to Sicily for several years.
 Polly's place in the family is filled by the heir to Lord Montdore's entailed fortune and title, Cedric Hampton. Born in Nova Scotia to a minor member of the Montdore family, Cedric has used his exceptional good looks and personal charm to establish a place within the homosexual milieu of the European aristocracy. He has lived a life of luxury as the lover of rich and aristocratic men. Cedric accepts an invitation to visit the Montdores. His natural love of beauty, innate good taste, and careful use of flattery enable Cedric to win the affections of Lord and Lady Montdore and many others. Cedric focuses his attentions upon Lady Montdore who uses Cedric's popularity and charm to reestablish herself as a leading society hostess, to Cedric's advantage.
 Fanny and Cedric soon become close friends. Polly and Boy return from Sicily, out of love and their marriage turned sour. While pregnant, Polly is regularly visited by the Duke of Paddington (a fictional title), who lavishes her with attention. There comes a reconciliation between Polly and Lady Montdore, Polly having borne a child who lived for minutes. "Cedric arranged the whole thing perfectly", according to Fanny. While Polly recovers from the difficult birth, Cedric sends Boy and Lady Montdore off to France, leaving Polly free to be carried off by the duke. He himself has fallen in love as well, but it is not revealed with who. The novel ends with Cedric and Fanny having tea at Montdore. While this outcome shocks the conservative social circles in which they mix, Fanny takes a more broad-minded view, pleased to see people she loves each finding happiness in their own way.
 Don't Tell Alfred (1960) is a sequel to the novel giving further insight into the married life of Fanny and Alfred.
