The Double Annotated

"The Double is a novella written by Fyodor Dostoevsky. It was first published on January 30, 1866.
The Double centers on a government clerk who goes mad. It deals with the internal psychological struggle of its main character, Yakov Petrovich Golyadkin, who repeatedly encounters someone who is his exact double in appearance but confident, aggressive, and extroverted, characteristics that are the polar opposites to those of the toadying pushover protagonist. The motif of the novella is a doppelganger.
Golyadkin is a titular councillor. This is rank 9 in the Table of Ranks established by Peter the Great. As rank eight led to hereditary nobility, being a titular councillor is symbolic of a low level bureaucrat still struggling to succeed. Golyadkin has a formative discussion with his Doctor Rutenspitz, who fears for his sanity and tells him that his behavior is dangerously antisocial. He prescribes cheerful company as the remedy. Golyadkin resolves to try this, and leaves the office. He proceeds to a birthday party for Klara Olsufyevna, the daughter of his office manager. He was uninvited, and a series of faux pas lead to his expulsion from the party. On his way home through a snowstorm, he encounters a man who looks exactly like him, his double. The following two thirds of the novel then deals with their evolving relationship."
