Dodsworth by Sinclair Lewis

They ceased to be children exploring together, rather happy in their loneliness. They were dominated by Endicott Everett Atkins and Madame de Penable and their smart groups. Madame de Penable saw that because in her fresh, keen, naive way Fran was different from European women, she was the more novel and attractive to the innumerable European men whom the De Penable always had about her, running her errands, drinking her excellent Moselle, listening to her scandalous anecdotes; she saw also that Sam was likely to keep Fran from snatching such of these men as the De Penable wanted to hold for her own.

She cultivated the Dodsworths enthusiastically.
