Jacob's Room centres, in a very ambiguous way, around the life story of the protagonist Jacob Flanders and is presented almost entirely through the impressions other characters have of Jacob. Thus, although it could be said that the book is primarily a character study and has little in the way of plot or background, the narrative is constructed with a void in place of the central character if, indeed, the novel can be said to have a 'protagonist' in conventional terms. The story is told mainly through the perspectives of the women in Jacob's life, including the repressed upper-middle-class Clara Durrant and the uninhibited young art student Florinda, with whom he has an affair.
