The following is an incomplete compendium of the fictional characters featured in the stories of P. G. Wodehouse (other than the ones already described in separate guides about Wodehouse series such as Blandings, Jeeves, etc.), in alphabetical order by surname.
The rather mild headmaster of Sanstead House during the events of The Little Nugget, Mr Arnold Abney is a tall and suave man, with a high forehead, thin white hands, a cooing intonation, and a general air of hushed importance.
Abney is an incorrigible namedropper, who rarely completes a sentence without mentioning some noble or important person of his acquaintance. His troublesome ward Ogden Ford refers to him as a 'hot air merchant'. He is also renowned for his propensity for 'popping up to London', generally to meet with some prospective aristocratic parent and invariably leaving his overworked masters in the lurch.
Abney is devoted to maintaining the good name of his school, and makes every effort to keep the boys in his charge from catching colds, both of which become difficult tasks with Ford around. Abney, having led a quiet and regular life, is suitably shocked to find his precious school overrun with gangsters.
Adair, a natural leader, a fit-looking sort of man with broad shoulders, light wiry hair, very bright blue eyes and a square jaw, is captain of cricket (and rugby) at Sedleigh in Mike and Psmith. He is mostly self-taught, and hard-working rather than talented; an orphan, his guardian suffers neuralgia at one end of him and gout at the other. He has a smouldering dislike for the likes of Stone and Robinson, who are apt not to take Sedleigh as seriously as Adair would like. At first he and Mike do not see eye to eye, but they later become firm friends.
A venerably white-bearded old man, a self-professed expert in eugenics, Appleby is in fact a crook, inveigling young Horace into the home of Cooley Paradene in order to rob him of his valuable collection of rare books, in Bill the Conqueror.
