While Nabokov's debut novel may initially appear simplistic compared to his later masterpieces, a closer examination reveals the seedlings of his distinctive style taking root. The protagonist, Ganin, embodies traits that will recur in Nabokov's subsequent characters, exemplified by his aloof nature and subtle rebelliousness. This is evident in the shrouded mystery of his true identity and his determination to cross borders illicitly. The recurring theme of a love triangle, a hallmark of Nabokov's narratives, is already present, adding layers of complexity beneath its seemingly straightforward surface.

Coincidence plays a pivotal role in Mary, foreshadowing Nabokov’s penchant for weaving seemingly disparate threads into a cohesive narrative tapestry. The shared boardinghouse of Ganin and Alfyorov, Mary’s arrival coinciding with Ganin’s departure, and references in Mary’s letters seamlessly blend into the fabric of the story, hinting at the intricate designs characteristic of Nabokov's later works.

The novel’s exploration of young love is imbued with a sense of sexual innocence and fervor, which may seem conservative when juxtaposed with Nabokov’s more mature offerings. Yet, this aspect can be seen as a vehicle for a deeper commentary. The conclusion of Mary, ostensibly a sentimental nod to an unattainable ideal, might also be interpreted as Nabokov’s sardonic challenge to conventional expectations. The bitter-sweet tone punctuates the narrative, laced with occasional hints of sourness that suggest the evolution of a more robust narrative style on the horizon.
