There, the leading pair are detached and led back down into the village by a boy, a boy who knows how lucky he is to have been given such a responsible job at such a young age. But on this day in May, on his return journey with the tired horses Pug and Delia, he spots what looks like a sheep sheltering on the hillside. But as he gets closer, his heart races as he becomes aware... it is not a sheep... it is a white dress...
