Kralefsky is Gerry's final tutor on Corfu. Gerry initially thinks that Kralefsky is more gnome than human, as he's bald and has a hunchback. Though he is an exacting tutor in all subjects, he also recognizes that he has more luck teaching Gerry when the subject matter appeals to his interests. To this end, Gerry learns French by reading a French bird guide. Kralefsky is an aviculturist (one who keeps and breeds birds), and the entire top floor of his mansion is lined with cages containing all manner of birds. He has a deep love of storytelling, though a number of his stories are presumably not true: Gerry discovers that he can surreptitiously plant an idea one day and the next day, Kralefsky has a story prepared involving "a Lady" and whatever situation Gerry might have suggested. However, Gerry doesn't always recognize that Kralefsky's stories are entirely fantasy: he takes Kralefsky at his word when Kralefsky regales him with a tale about wrestling a famous wrestler in Paris and begs for a wrestling lesson, during which he ends up seriously hurting Kralefsky.
