The Uncommon Reader

From Alan Bennet's The Uncommon Reader:
Less to her credit, before Norman's mysterious departure the Queen had begun to wonder if she was outgrowing him... or rather, out-reading him.Once upon a time he had been a humble and straightforward guide to the world of books. He had advised her as to what to read and had not hesitated to say when he thought she was not ready for a book yet. Beckett, for instance, he had kept from her for a long while and Nabokov and it was only gradually he had introduced her to Philip Roth (with Portnoy's Complaint quite late in the sequence).
