...in which we take a stroll down memory lane along that finest of lakes – Buttermere – journeying from the bluebells of Rannerdale to Gatesgarth, a farm with a remarkable history. As we wander, with Angus Winchester, Professor Emeritus in the Department of History, Lancaster University, who was bought up in Lorton Vale, we talk about fact and bloody fiction in 'the secret valley'; the tragic charms of Buttermere's famous Maid; the crucial role Gatesgarth played in establishing the Herdwick breed; and the unlikely reason behind the name Innominate Tarn.
