The Inimitable Jeeves:

Bertie Wooster's friend Richard "Bingo" Little is forever falling in love with a wide variety of women, and it is up to Bertie, with the aid of Jeeves, his valet, to promote or prevent these romances, depending on the suitability of the young lady. At the beginning of The Inimitable Jeeves, Bingo is infatuated with a waitress and wants Bertie to make his Uncle Mortimer, the source of his income, receptive to the idea. Jeeves suggests having Bingo read the uncle such Rosie M. Banks novels as Only a Factory Girl, in which "marriage with young persons of an inferior social status" is advocated. Bertie has to pretend that he writes the Banks novels to encourage Uncle Mortimer further. These machinations result in the uncle marrying his cook, previously Jeeves's intended. Jeeves has been plotting for this eventuality since becoming friendly with the waitress Bingo loves. Bingo next falls for Honoria Glossop, but Bertie's domineering Aunt Agatha wants her nephew to marry Honoria. Deciding to get out of this jam without Jeeves's help, Bertie pushes Honoria's young brother into a pond so that Bingo can save the boy and be a hero in his beloved's eyes, but on his way to the pond, fickle Bingo discovers someone else. Bertie finds himself engaged to Honoria, who says that he must get rid of Jeeves. The valet conspires with Claude and Eustace, Bertie's prankster twin cousins, to convince Honoria's father, Sir Roderick, a prominent psychiatrist, that Bertie is crazy.
