What is England and who are the English? There is a line from one end of England to the other. This is the line of longitude - 2 degrees west - and it describes a cross-section through the country. The author follows this line as closely as physically possible on foot - terrain ranging from open moorland to urban back-streets. The line begins at Berwick-on-Tweed on the border with Scotland and runs south through the wilds of Northumberland and includes the Yorkshire Dales, Pennines, Birmingham suburbs, Cotswolds, Salisbury Plain, Dorset and Isle of Purbeck.
