The New Machiavelli purports to be written in the first person by its protagonist, Richard "Dick" Remington, who has a lifelong passion for "statecraft" and who dreams of recasting the social and political form of the English nation. Remington is a brilliant student at Cambridge, writes several books on political themes, marries a wealthy heiress and enters parliament as a Liberal influenced by the socialism of a couple easily recognisable as the Webbs, only to go over to the Conservatives. Remington undertakes the editing of an influential political weekly and is returned to parliament on a platform advocating the state endowment of mothers but his career is wrecked by his love affair with a brilliant young Oxford graduate, Isabel Rivers. When rumours of their affair begin to circulate, Remington tries to break it off but then resolves to abandon wife, career, party and country to live in Italy, where he writes the apologia pro vita sua that the novel constitutes.
