You learn a lot, writing fiction.

I have long been interested in landscape history, and when younger and more robust I used to do much tramping of the English landscape in search of ancient field systems, drove roads, indications of prehistoric settlement. Towns and cities, too, which always retain the ghost of their earlier incarnations beneath today's concrete and glass.

Every novel generates its own climate, when you get going.

I have had to empty two family homes during the last few years - first, the house that had been my grandmothers since 1923, and then my own country home, which we had lived in for over twenty years.

We all need a past - that's where our sense of identity comes from.

I'm not an historian and I'm not wanting to write about how I perceive the social change over the century as a historian, but as somebody who's walked through it and whose life has been dictated by it too, as all our lives are.

Language tethers us to the world; without it we spin like atoms.
