The entirety of Frankenstein is contained within Robert Walton’s letters, which record the narratives of both Frankenstein and the monster, to his sister (even Shelley’s preface to the book can be read as an introductory letter). Walton’s epistolary efforts frame Victor’s narrative, which includes letters from Alphonse and Elizabeth. Like Walton’s, these letters convey important information that serves to advance the plot and offer some sense of authenticity to an implausible story. Additionally, Victor’s inclusion of these personal letters in his narrative allows Alphonse and Elizabeth to express themselves, shedding light on their respective concerns and attitudes, and thus rendering them more human.

Shelley’s use of letters enables the shift of narrative from one character to another while remaining within the bounds of the standard novel. Letters also serve as a means of social interaction, as characters are frequently out of immediate contact with one another. Walton never encounters his sister in the novel; his relationship with her is based wholly on correspondence. Likewise, Victor often isolates himself from his loved ones; the letters from Alphonse and Elizabeth mark attempts to connect with him. Even the monster uses written communication to develop a relationship with Victor when, at the end of the novel, he leads him ever northward by means of notes on the trees and rocks he passes.

Women in Frankenstein are generally pure, innocent, and passive. Though there are a few exceptions, such as Caroline Beaufort, who works to support her impoverished father, women are generally seen as kind but powerless. For example, Elizabeth stands up for Justine’s innocence but cannot prevent her execution. For both Victor and the monster, woman is the ultimate companion, providing comfort and acceptance. For Victor, Elizabeth proves the sole joy that can alleviate his guilty conscience; similarly, the monster seeks a female of his kind to commiserate with his awful existence. Each eventually destroys the other’s love interest, transferring woman’s status from object of desire to object of revenge; women thus are never given the opportunity to act on their own.

In the context of passive female characters, it is interesting to note that Mary Shelley’s mother, Mary Wollstonecraft, was the author of the strongly feminist A Vindication of the Rights of Woman. One can argue that Frankenstein represents a rejection of the male attempt to usurp (by unnatural means) what is properly a female endeavor—birth. One can also interpret the novel as a broader rejection of the aggressive, rational, and male-dominated science of the late seventeenth and early eighteenth century. Though it was long met with mistrust, this science increasingly shaped European society. In this light, Frankenstein can be seen as prioritizing traditional female domesticity with its emphasis on family and interpersonal relationships.
