Ian Crofton makes a journey on foot from Gretna Green in the southwest to Berwick in the northeast, following as close as possible the Anglo-Scottish Border as it has been fixed since the union of the the crowns in 1603. 'Walking The Border' is in the best traditions of travel writing, combining vivid description with human insight, the whole spiced with a wry sense of the absurdity and necessity of both inward and outward journeys.
