We fantasise about what we would do if we inherited a fortune: the house on Cheyne Walk? The Manolo Blahniks? The racehorses? But what would it be like, never to have to dream in that way? Laura Thompson explores the historical phenomenon of the heiress in four inviting categories.

Then, as the shadows crept over 1930s Europe, the stark - and very public - differences in their outlooks came to symbolize the political polarities of a dangerous decade.

The divorce proof which shocked Britain in the so-called "Swinging '60s" when the 11th Duke of Argyll divorced his second wife Margaret amidst enough dirty linen to give the "investigative journalists" of the time enough copy to last for decades. The Duchess was the Paris Hilton of her time but in a more judgmental age. She paid the price financially then socially when His Grace produced the infamous "headless man" Polaroids at the divorce proof, ensuring her eternal ridicule and sparking off a debate about the link between morality and national decline.

When Queen Mary died in 1953, James Pope-Hennessy was commissioned to write an official biography of her - unusual for a Queen Consort. Queen Mary's life, contrary to popular belief, was essentially dramatic, and she played a far more important and influential role in the affairs of the British monarchy than her public image might have otherwise suggested. Using material from the Royal Archives, private papers and Queen Mary's personal diaries and letters, Pope-Hennessy's biography was a remarkable portrait of a remarkable woman and received rave reviews across the press. 

 New York Times best-selling author and journalist Anderson Cooper teams with New York Times best-selling historian and novelist Katherine Howe to chronicle the rise and fall of a legendary American dynasty - his mother’s family, the Vanderbilts.  

The lasting reputation of George V is for dullness. He was a crack shot and an outstanding stamp collector, but that's about it. The flamboyance and hedonism of his father, Edward VII, defined an era whose influence and magnetism is still felt today. The contrast between the two could hardly be greater.

Traitor King, by Sunday Times best-selling author Andrew Lownie, looks at the years following the abdication of Edward VIII when the former king was kept in exile, feuding with his family over status for his wife, Wallis Simpson, and denied any real job.

Maria Callas (1923-1977) was the greatest opera diva of all time with a career that remains unmatched by any prima donna. Much of her life was overshadowed by her fiery relationship with Aristotle Onassis, who broke her heart when he left her for Jacqueline Kennedy, and her reputation was marred by legendary tantrums on and off the stage. 

A major figure behind his nephew Philip's marriage to Queen Elizabeth II and instrumental in the royal family taking the Mountbatten name, Dickie Mountbatten's career included being Supreme Allied Commander of South East Asia during World War Two and the last Viceroy of India. Once the richest woman in Britain and a playgirl who enjoyed numerous affairs, Edwina Mountbatten emerged from World War Two as a magnetic and talented charity worker loved around the world.

Queen Bees looks at the lives of six remarkable women who made careers out of being society hostesses, including Lady Astor, who went on to become the first female MP, and Mrs Greville, who cultivated relationships with Edward VII, as well as Lady Londonderry, Lady Cunard, Laura Corrigan and Lady Colefax. Told with wit, verve and heart, Queen Bees is the story of a form of societal revolution and the extraordinary women who helped it happen.

Through extensive interviews with the closest friends, lovers, and relatives of Onassis and the Kennedys, longtime journalist Evans has uncovered the shocking culmination of the Kennedy-Onassis-Kennedy love triangle: Aristotle Onassis was at the heart of the plot to kill Bobby Kennedy. Meticulously tracing Onassis's connections in the world of terrorism, Nemesis presents compelling evidence that he financed the assassination - including a startling confession that has gone unreported for nearly three decades.

Hugo Vickers's life took a dramatic turn in 1979 when the legendary Sir Cecil Beaton invited him to be his authorised biographer. The excitement of working with the famous photographer was dashed only days later when Cecil Beaton died. But the journey had begun - Vickers was entrusted with Beaton's papers, diaries and, most importantly, access to his friends and contemporaries. The resulting book, first published in 1985, was a best seller. In Malice in Wonderland, Vickers shares excerpts from his personal diaries kept during this period.

The season of 1939 brought all those 'in Society' to London. The young debutante daughters of the upper classes were presented to the king and queen to mark their acceptance into the new adult world of their parents.

There was nothing to do but wait - and dance. 

Dozens of young American heiresses married into the British peerage, bringing with them all the fabulous wealth, glamour and sophistication of the Gilded Age.
