If I Were You is Wodehouse's comic variation on a favourite theme of Victorian melodrama - the changeling. Did old Nannie Price really substitute her own child for the infant son of the late Lord and Lady Droitwich while they were away in India? If so, Tony Droitwich is heir, not to rolling acres and a stately pile, but to a barber's shop in London's West End. With Socialist Syd Price determined to prove himself the new earl, and Tony's haughty relations determined that he shall not, the stage is set for an amusing battle, waged by a familiar Wodehousean cast of fat butlers, tough aunts, lively American girls and drawling dandies.
