There is scene in the film Sex and the City that has sent its mostly female fans crowding into bookshops, only to emerge empty-handed. But the trouble with the movie of Sex and the City is that so much of it is fake. For instance, the quotations that Carrie read out were real but the tome itself did not exist, much to the exasperation of booksellers inundated by hundreds of would-be customers wanting copies. In it, you can dip into letters from the poet John Keats, who died young and did not always get on well with women. In fact, he once complained in a letter to a male friend: "When I am among women I have evil thoughts, malice, spleen — I cannot speak or be silent — I am full of suspicions and therefore listen to nothing — I am in a hurry to be gone.
