The afternoon had turned overcast and sultry, and Sawrey drowsed in the growing July heat. Clouds of tiny midges—thunderflies, people called them—very small and black, and thought to be a sign of a coming storm, gathered in the air all over the village. […] And whilst thunderflies didn’t bite or sting, they got in one’s eyes and one’s mouth and were certainly aggravating.
