Antonia Fraser and Harold Pinter
As the world now knows from the frank and eccentric memoir that uses the question as its title, "Must you go?" were the words that started the 33-year love affair between the posh historian and the truculent East End-born playwright. It was at a dinner party in 1975. She was heading home, anticipating the school run in the morning. Instead, she and Harold talked until 6am, and that was that. When she told her husband of her new love, he said: "The best living playwright. Very suitable."
She was a Catholic, but the church granted them a dispensation so that they could marry in church. They airily survived the moralising of the press; and life became a succession of first nights, literary dinners, foreign tributes and the shared intimacies of life in Holland Park.
Garlanded with the Nobel Prize and a Companionship of Honour, he left her on Christmas Eve 2008, when cancer claimed him. His biographer, Michael Billington, wrote: "Harold and Antonia, as a pair of strong-willed and impassioned romantics, were that rare thing: a perfect match."
