Love in a Cold Climate is a British television serial drama produced by the BBC in association with WGBH Boston, and first broadcast in two parts on BBC One on 4 and 11 February 2001.
 The serial was adapted by Deborah Moggach from Nancy Mitford's novels "The Pursuit of Love" and "Love in a Cold Climate", and was directed by Tom Hooper.
Nancy Freeman-Mitford {'1': ", '2': ", '3': ", '4': "} (28 November 1904 – 30 June 1973), known as Nancy Mitford, was an English novelist, biographer and journalist.
 One of the renowned Mitford sisters and one of the "Bright Young People" on the London social scene in the inter-war years, she is best remembered for her novels about upper-class life in England and France and for her sharp and often provocative wit.
 She also established a reputation for herself as a writer of popular historical biographies.
The Anthony Powell Society is an international literary society dedicated to the works of English novelist Anthony Powell.
 Membership is open to all interested in "A Dance to the Music of Time" and Powell's other works.
The Pursuit of Laughter is a 2008 collection of diaries, articles, reviews and portraits by Diana Mitford.
 The book was published by Gibson Square and edited by Martin Rynja.
 Mitford's sister, Deborah Cavendish, Duchess of Devonshire, provides the introduction.
 The title is a homage to another Mitford sister's book, Nancy Mitford's "The Pursuit of Love".
Noblesse Oblige: An Enquiry Into the Identifiable Characteristics of the English Aristocracy (1956) is a book that purports to be edited by Nancy Mitford, illustrated by Osbert Lancaster, caricaturist of English manners, and published by Hamish Hamilton.
 The anthology comprises four brief essays by Nancy Mitford, Alan S. C. Ross, “Strix” and Christopher Sykes, a letter by Evelyn Waugh, and a poem by John Betjeman.
The Bright Young Things, or Bright Young People, was a nickname given by the tabloid press to a group of bohemian young aristocrats and socialites in 1920s London.
 They threw elaborate fancy dress parties, went on elaborate treasure hunts through nighttime London, drank heavily and used drugs—all of which was enthusiastically covered by journalists such as Tom Driberg.
 They inspired a number of writers, including Nancy Mitford ("Highland Fling"), Anthony Powell ("A Dance to the Music of Time"), Henry Green ("Party Going") and the poet John Betjeman ("A Subaltern's Love Song").
 Evelyn Waugh's 1930 novel "Vile Bodies", adapted as the 2003 film "Bright Young Things", is a satirical look at this scene.
 Cecil Beaton began his career in photography by documenting this set, of which he was a member.
Wigs on the Green is a novel by Nancy Mitford, first published in 1935.
 A merciless satire of British Fascism, the book is notable for lampooning the political enthusiasms of Mitford's sisters Unity Mitford and Diana Mosley.
 2010 saw its first reprint in the United Kingdom and the United States in more than thirty-five years.
Agents and Patients is the fourth novel by the English writer Anthony Powell.
 It combines two of the aspects of 1930s life, film and psychoanalysis.
 In what Powell himself has acknowledged is a "roman a clef" of sorts (Anthony Powell, "Journals 1987-1989", 121), a comically critical eye is cast across "entre deux guerres" society and its often self-indulgent, usually unsatisfied quest for contentment.
Anthony Dymoke Powell ( ; 21 December 1905 – 28 March 2000) was an English novelist best known for his twelve-volume work "A Dance to the Music of Time", published between 1951 and 1975.
A Life of Contrasts is an international bestseller by Diana Mitford (sister of novelist Nancy Mitford, journalist Jessica Mitford, and memoirist Deborah, Duchess of Devonshire) that was first published by Hamish Hamilton in 1977.
 She later released a revised edition of the book, published in 2002 by Gibson Square.
