My latest column for Prospect magazine is about the joys of walking at night time, an enthusiasm I share with Dorothy and William Wordsworth, Coleridge and Dickens. Full text on the Prospect website here, or after the fold. I’ve been doing a lot more of it recently, while staying up writing into the early hours.

But other times I really enjoy those long hours of darkness, after everyone is in bed, when I can get in great stretches of concentrated writing time – and a wander through deserted lanes and fields under starlight.
