The protagonist, Yakov Petrovich Golyadkin, experiences a psychological fracture when he encounters an exact physical double who begins to systematically usurp his social and professional standing. Golyadkin, a timid and insecure titular councillor, struggles to maintain his sanity as his doppelgänger—who possesses all the social graces and manipulative cunning he lacks—insinuates himself into his life. The narrative follows Golyadkin’s descent into paranoia and social isolation as he attempts to confront the entity that mirrors his own identity. Written in a frantic, claustrophobic third-person limited perspective, the text mirrors the protagonist's own mental disintegration through its repetitive and obsessive prose style.

This work is frequently analyzed as a foundational text in psychological realism that anticipates the existentialist concerns of later literature. Critics often highlight the innovative use of a double to externalize the protagonist's internal conflict and self-loathing. The narrative's relentless pacing and claustrophobic tone are noted for effectively placing the reader inside the deteriorating mind of the central character. Scholars suggest that the text serves as a biting critique of the social pressures and status anxieties inherent in the bureaucratic systems of the time.
