The Adventures of Sally, P.G. Wodehouse

Life was always simple for Sally Nicholas-until she became rich. Being unaccustomed to possessing a great deal of money, Sally hasn't gotten the hang of it yet. This explains why she agrees to back a show written by her fiancé Gerald and staged by her brother, Fillmore. It seems like a good way to make them all happy ... but when Ginger Kemp, a rather hopeless, charming young man Sally met in Roville, appears in America and offers not-very-glad tidings about Gerald, he really puts the cat among the pigeons.
