Blackberries this year have been wonderful. From early August until a few days ago, I’d come home from every country walk with stained lips and fingers, and a bag full of purple fruits. But it’s all over now, because on 29th September, Michaelmas Day, the Devil came along, as he does every year, and spat on every remaining berry. If you favour the old Church calendar, you’ve got till 10th October, but whichever one you follow, blackberrying’s pretty much over for another year. The Devil is not kind.
