The Double: Dvojnik

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 Double is the most Gogolesque of Dostoyevsky's works; its subtitle "A Petersburg Poem" echoes that of Gogol's Dead Souls.
