Kate Heron, a wealthy, charming widow, has married a man ten years her junior, the attractive and feckless Dermot. Their special love arms them against the disapproval of conservative friends and neighbors—until the return of Kate's old friend Charles, intelligent, kind, and now widowed with a beautiful daughter. At first Kate watches happily as the two families are drawn together, only dimly aware of the subtle undercurrents beginning to disturb the calm surface of their friendship. Before long, however, even she cannot ignore the gathering storm.
