Wharton's second country was France: she started living there in 1907, wrote a book about driving through the provinces (A Motor-Flight Through France), was given the legion d'honneur for her war-work, and was buried at Versailles in 1937. The Custom of the Country is her greatest novel of the Franco-American relationship, whose complexities are blundered into, overridden, understood and misunderstood by the impeccably named Undine Spragg.
