"This image provided by Viking shows the cover of the book ""American Lady: The Life of Susan Mary Alsop,"" by Caroline de Margerie. At its heart, this engaging, gentle biography is a tale of how a particular slice of the other half lived -- in today's parlance, that's the 2 percent -- in the mid-20th century. With its focus on class, events of the day, and love affairs, it's a one-woman ""Downton Abbey"" for the Yankee political class. (AP Photo/Viking)"
