My sister gave me Copsford (1948). It was clearly a book she loved, and its author – Walter Murray – was someone we’d once known. So it seemed odd I’d never heard of it. It’s a strange, exhilarating book about a solitary year spent wholly absorbed in the natural world – a book in the tradition that runs from Richard Jefferies to Robert Macfarlane and perhaps has roots in Wordsworth too, and John Clare in saner moments. But though it has devotees and is reissued now and then, it has never been widely read. In fact most people, like me, have never heard of it.
