In north Devon, artist Steve Pleydell-Pearce veers off from his normal coastal hotspots for Speke's Mill Mouth Waterfall, hoping to capture the grandeur and majesty of the landmark. Steeplejack Andrew Tarplee takes on an ancient church tower in the village of Paul in Cornwall, where he abseils down the 800-year-old tower to repair and repaint its clock faces, protecting them from the ravages of time.
