I was 6 when I was given the new Puffin edition of Rumer Godden’s The Dolls’ House (1947). ‘This is a novel written about dolls in a dolls’ house,’ it begins. It was the first novel I’d ever read, arriving just at the point where I’d cracked the secret pleasure of reading to myself. We lived in Newcastle then, by the railway line. By that time, I had three younger siblings. It must have been one afternoon, when the others were downstairs, that I went up to the bedroom with my book to be alone. As the eldest I carried a certain weight: I was expected to set an example, to be grown-up, responsible. But I also got to do the first things first: first, most memorably, to read a book on my own, to make the leap, unaccompanied and unmediated, into that pocket of time and space, that dream-concoction of light and heat and air, which was – though it rose inexplicably from inside me – an entry to another world.
