Motifs are recurring structures, contrasts, or literary devices that can help to develop and inform the text’s major themes.
The text repeatedly depicts Hyde as a creature of great evil and countless vices. Although the reader learns the details of only two of Hyde’s crimes, the nature of both underlines his depravity. Both involve violence directed against innocents in particular. In the first instance, the victim of Hyde’s violence is a small, female child whom he tramples; in the second instance, it is a gentle and much-beloved old man. The fact that Hyde injures a girl and ruthlessly murders a man, neither of which has done anything to provoke his rage or to deserve death, emphasizes the extreme immorality of Jekyll’s dark side unleashed. Hyde’s brand of evil constitutes not just a lapse from good but an outright attack on it.
Repeatedly in the novel, characters fail or refuse to articulate themselves. Either they seem unable to describe a horrifying perception, such as the physical characteristics of Hyde, or they deliberately abort or avoid certain conversations. Enfield and Utterson cut off their discussion of Hyde in the first chapter out of a distaste for gossip; Utterson refuses to share his suspicions about Jekyll throughout his investigation of his client’s predicament. Moreover, neither Jekyll in his final confession nor the third-person narrator in the rest of the novel ever provides any details of Hyde’s sordid behavior and secret vices. It is unclear whether these narrative silences owe to a failure of language or a refusal to use it.
Ultimately, the two kinds of silence in the novel indicate two different notions about the interaction of the rational and the irrational. The characters’ refusals to discuss the sordid indicate an attribute of the Victorian society in which they live. This society prizes decorum and reputation above all and prefers to repress or even deny the truth if that truth threatens to upset the conventionally ordered worldview. Faced with the irrational, Victorian society and its inhabitants prefer not to acknowledge its presence and not to grant it the legitimacy of a name. Involuntary silences, on the other hand, imply something about language itself. Language is by nature rational and logical, a method by which we map and delineate our world. Perhaps when confronted with the irrational and the mystical, language itself simply breaks down. Perhaps something about verbal expression stands at odds with the supernatural. Interestingly, certain parts of the novel suggest that, in the clash between language and the uncanny, the uncanny need not always win. One can interpret Stevenson’s reticence on the topic of Jekyll’s and Hyde’s crimes as a conscious choice not to defuse their chilling aura with descriptions that might only dull them.
Throughout the novel, Stevenson goes out of his way to establish a link between the urban landscape of Victorian London and the dark events surrounding Hyde. He achieves his desired effect through the use of nightmarish imagery, in which dark streets twist and coil, or lie draped in fog, forming a sinister landscape befitting the crimes that take place there. Chilling visions of the city appear in Utterson’s nightmares as well, and the text notes that
In such images, Stevenson paints Hyde as an urban creature, utterly at home in the darkness of London—where countless crimes take place, the novel suggests, without anyone knowing.
