Herefordshire bristles with castle ruins and earthworks if not the terraces and water features of mediaeval castle gardens. So we sort out Clifford Castle; the birthplace of the twelfth-century Rosamund de Clifford. The secret garden created for her at Woodstock in Oxfordshire by Henry II is still remembered on the Blenheim estate as Rosamund’s Bower. Her Herefordshire birthplace, high above the River Wye, is guarded by Paul and Lizzie. They have restored the adjacent Edwardian house and cleared away the invading brambles despite the interruptions of belligerent birds roosting in the castle ruins and unexplained forces moving objects around the house. Lizzie has concluded that Rosamund’s home stands at the confluence of three lines of elemental force.
