Fellowes, a late bloomer who wrote the script for "Gosford Park," again portrays the British upper class in his début novel. One Edith Lavery marries up, snagging the Earl of Broughton, a man who lives for his country estates and thanks his wife after each of their brief sexual encounters. Edith soon takes up with a handsome actor and runs for cover from her mother-in-law, the formidable Googie. The polite firefights that ensue are very readable, but their presentation is somewhat muddled. Fellowes, who, the dust jacket reveals, has a son named Peregrine and a dachshund named Fudge, may identify too closely with this social stratum. Although he convincingly portrays the habits of the entitled, they escape the skewering that the title leads us to expect. The result is a watered-down satire that eventually becomes an apologia for Edwardian England, where everyone knew his place and no one was tacky.
