Although Utterson witnesses a string of shocking events, Utterson himself is a largely unexciting character and is clearly not a man of strong passions or sensibilities. Indeed, Stevenson intends for him to come across in this way: from the first page of the novel, the text notes that Utterson has a face that is “never lighted by a smile,” that he speaks very little, and that he seems “lean, long, dusty, [and] dreary.” Yet, somehow, he is also “lovable,” and dull and proper though he may be, he has many friends. His lovability may stem from the only interesting quality that Stevenson gives him—namely, his willingness to remain friends with someone whose reputation has suffered. This loyalty leads him to plumb the mystery that surrounds Jekyll.
Utterson represents the perfect Victorian gentleman. He consistently seeks to preserve order and decorum, does not gossip, and guards his friends’ reputations as though they were his own. Even when he suspects his friend Jekyll of criminal activities such as blackmail or the sheltering of a murderer, he prefers to sweep what he has learned—or what he thinks he has learned—under the rug rather than bring ruin upon his good friend.
Utterson’s status as the epitome of Victorian norms also stems from his devotion to reason and common sense. He investigates what becomes a supernatural sequence of events but never allows himself to even entertain the notion that something uncanny may be going on. He considers that misdeeds may be occurring but not that the mystical or metaphysical might be afoot. Thus, even at the end, when he is summoned by Poole to Jekyll’s home and all the servants are gathered frightened in the hallway, Utterson continues to look for an explanation that preserves reason. He desperately searches for excuses not to take any drastic steps to interfere with Jekyll’s life. In Utterson’s devotion to both decorum and reason, Stevenson depicts Victorian society’s general attempt to maintain the authority of civilization over and against humanity’s darker side. Stevenson suggests that just as Utterson prefers the suppression or avoidance of revelations to the scandal or chaos that the truth might unleash, so too does Victorian society prefer to repress and deny the existence of an uncivilized or savage element of humanity, no matter how intrinsic that element may be.
Yet, even as Utterson adheres rigidly to order and rationality, he does not fail to notice the uncanny quality of the events he investigates. Indeed, because we see the novel through Utterson’s eyes, Stevenson cannot allow Utterson to be too unimaginative—otherwise the novel’s eerie mood would suffer. Correspondingly, Stevenson attributes nightmares to Utterson and grants him ominous premonitions as he moves through the city at night—neither of which seem to suit the lawyer’s normally reasonable personality, which is rarely given to flights of fancy. Perhaps, the novel suggests, the chilling presence of Hyde in London is strong enough to penetrate even the rigidly rational shell that surrounds Utterson, planting a seed of supernatural dread.
