The narrative follows her attempt to navigate the rigid social expectations of the late 1800s while uncovering the dark secrets hidden within her new home.

This novel aligns with the classic conventions of the Gothic genre, emphasizing the vulnerability of a young woman thrust into an unfamiliar and threatening environment. The narrative structure relies on the slow accumulation of dread, mirroring the protagonist's own confusion as she attempts to discern reality from paranoia. Readers often note the effectiveness of the Victorian setting in heightening the sense of entrapment and social pressure. The story functions as a study of how external manipulations can destabilize an individual's sense of security within a domestic sphere.
