Adventures of Sally, The by P. G. Wodehouse (1881 - 1975)

This romantic comedy stars a young American girl named Sally, who inherits a considerable fortune and finds her life turned upside down. The typically Wodehouseian cast includes Sally's ambitious brother, an assortment of theater people, a pair of English cousins, and, of course, an Uncle. It's jolly good fun!
