The past is not past for Katharine Merrill. Even after two decades of volatile marriage, Katharine still believes she can have the life that she felt promised to her by those first exhilarating days with her husband, Frederick. For two months, just before Frederick left to fight in World War II, Katharine received his total attentiveness, his limitless charms, his astonishing range of intellect and wit. Over the years, however, as Frederick’s behavior and moods have darkened, Katharine has covered for him, trying to rein in his great manic passions and bridge his deep wells of sadness: an unending project of keeping up appearances and hoping for the best. But the project is failing. Increasingly, Frederick’s erratic behavior, amplified by alcohol, distresses Katharine and their four daughters and gives his friends and family cause to worry for his sanity. When, in the summer of 1962, a cocktail party ends with her husband in handcuffs, Katharine makes a fateful decision: She commits Frederick to Mayflower Home, America’s most revered mental asylum.
