Walkhampton, Dartmoor A shepherd on his quad bike remarks on the contrast with last week’s rain, wind and mud

From the western edge of Dartmoor, heat haze obscures views towards familiar territory in the Tamar Valley. Up here, by Lowery Cross, in sight of glittering ripples on Burrator Reservoir, ponies graze among dazzling yellow gorse; drab turfy banks are starred with a few violets, and the sound of chiffchaff echoes from coniferous plantations.

One realised as he told in illustration of his subject, “Animal Heroes,” the story of the French wolf which was killed in the mountains of Gévaudan, what terror “the beast” must have inspired in the hearts of the 40,000 peasants who turned out to round up this hero-murderer of a hundred children.
