Edwin Grieve journeys down Coquetdale, Redesdale and North Tynedale in a close look at West Northumberland. From Kielder Water and the Cheviot Hills, to the lush, wooded valleys of Tynedale and Hadrian's Wall. From Imperial Rome to George Stephenson and the industrial age, remote waterfalls, sleepy villages and castles in the land of the Border Reivers.
