That is how J.B. Priestly once described British author Dorothy Whipple (1893-1966, born and died in Blackburn, Lancashire). The blog Lakeside Musing has written a review of Dorothy's novel Someone at a Distance, first published 1953 and republished last year. Rather than repeat what the muser by the side of the lake had to say, I'll let that review speak for itself.
Dorothy is mentioned on the Whipple Website's Fiction by Whipples page. You can also read about her in Wikipedia.
