A modern collision of French and American mores begins in near farce but ends in tragedy in Johnson's bright, unsparing novel. Johnson (Health and Happiness, 1990, etc.) traces what happens as uncomprehending members of two very different cultures attempt to understand one another. The often droll results are catalogued by Isabel Walker, a young woman sent from her native California to help her beleaguered stepsister. Roxanne Walker de Persand--a poet long resident in Paris, with a French husband (Charles-Henri, a moderately successful painter) and a young daughter--is pregnant again when she learns that her husband is having an affair with a married woman. Charles-Henri's elegant family, led by a daunting matriarch, become involved in the efforts to resolve the domestic drama. After all, they suggest, men must have their little follies. Isabel, bright, inquisitive, anxious to sample life, serves as a go-between, and along the way herself begins an affair with Edgar, an urbane diplomat and wonderfully self-assured lover some 50 years her senior. The rest of Isabel's well-heeled but somewhat contentious family arrive, and a marvelous scene ensues in which the Walkers and de Persands sit down for a meal and gradually realize that their tastes and ideas are hopelessly at odds. Johnson is especially good at catching the class-bound, cool, utter self- assurance of the French upper classes, and the determinedly frank, aggressive innocence of their American counterparts. Violence erupts when the husband of Charles-Henri's mistress goes on a shooting spree. There will be several deaths and some surprising but believable revelations about many of these people before Isabel emerges into her own, the only character to begin to grasp the limitations of each side of her transatlantic family. A shrewd, carefully detailed portrait of the ways in which Americans and the French continue to romanticize, denigrate, and misapprehend each other, contained in a well-paced, believably dramatic narrative.
