Had the dogs not taken exception to the strange van parked in the royal grounds, the Queen might never have learnt of the Westminster travelling library's weekly visits to the palace. But finding herself at its steps, she goes up to apologise for all the yapping and ends up taking out a novel by Ivy Compton-Burnett, last borrowed in 1989. Duff read though it proves to be, upbringing demands she finish it and, so as not to appear rude, she withdraws another. This second, more fortunate choice of book awakens in Her Majesty a passion for reading so great that her public duties begin to suffer. And so, as she devours work by everyone from Hardy to Brookner to Proust to Samuel Beckett, her equerries conspire to bring the Queen's literary odyssey to a close.
