The magnetic Evelyn Gresham, 52, is a�barrister of considerable distinction. He has everything life could offer?a gracious riverside house in Berkshire, a beautiful young wife, Imogen, who is devoted to him, and their 11-year-old son, a replica of his father. Their nearest neighbor is Blanche Silcox, a plain, tweed-wearing woman of�50 who rides, shoots, fishes, and drives a Rolls Royce?in every way the opposite of the domestic, loving Imogen.�Their world is conventional country life at its most idyllic: how can its gentle surfaces be disturbed?
