Among many qualities that Dexter and Jean-Baptiste Grenouille share, one of them is the propensity to murder ritualistically. Dexter kills ritualistically because in order for him to evade prosecution for his crimes, he must be incredibly meticulous in his methods of murder. For Dexter, the ritual is part of the rush because in having a certain process that he chose, he exercises the ultimate element of control. Each person that he kills dies the same way, is disposed of the same way, and generates the same kind of peace in Dexter by satiating his Dark Passenger. The knowledge that one more creep, rapist, drug dealer, or murderer, who has slipped through the cracks of the corrupted Miami-Dade justice system is off the streets relaxes him. However, in Season 2 (SPOILER ALERT) Dexter’s dumping area (a remote area off the coast of Miami) has been discovered by several scuba divers who are horrified at the discovery, which prompts a widespread investigation of the identities and murderer of the victims as well as our own emotional investment in whether or not Dexter will be able to survive such an indictment if it ever reaches him. This derails Dexter’s typical ritual behavior and forces him to adapt not to killing in a new way, but disposing in a new way. This ability to adapt and adjust to certain conditions indicates how well-trained he is to be a hunter of evil men.

In contrast, Jean-Baptiste Grenouille’s ritual is not so much about the killing as it is about the preservation of feminine scent. His first kill was completely accidental, but the scene that immediately follows the girl’s death precludes what happens next – Grenouille is going to find a way to preserve unique human scent. After the girl is dead, he indiscriminately rips open her corset and dress, exposing basically her entire nude body. He cups his hands around almost every part of her body in order to indulge in her scent, but her death has rendered her scentless. He becomes disillusioned and fearful that he will never learn how to preserve scent, his sole love and obsession. When he becomes an apprentice to Giuseppe Baldini, he learns how to extract scent from flowers and herbs and whatnot, but because he is socially stunted, he does not realize that even though glass and cats have smells, their essence cannot be extracted. Grenouille tests several methods of perfuming, and the one that succeeds necessitates murder. Grenouille is no misogynist; he simply finds the scents of beautiful women to be precious and worth preserving. His experience with the death of the first girl inspires a fear in him that if he cannot preserve, the unique individual scent will be lost forever.

The actual process that Grenouille uses to capture human scent follows the general principles of enfleurage (a process that uses odorless fats that are solid at room temperature to capture the fragrant compounds exuded by plants), he succeeds in preserving the scent of a woman by cutting her hair, covering her in animal fat, and then distilling the fat. One thing that I find particularly interesting about this ritual is how delicately Grenouille handles his women while they still possess their scent, yet how crudely he disposes of the bodies afterward. It is not because he has distaste for women, but these people are no longer useful to him: they are scentless. In a way, this reflects many of the internal struggles he faces. Grenouille himself has no scent. Any reminder of that fact, for instance, a scentless woman lying around in his workshop, would only distress him. I also find the level of intimacy in the process very interesting. The women are completely nude, dead, wrapped in animal fat, and their unique scent is in a way completely siphoned from their bodies: it is not perhaps only their olfactory essence, but their essence of life. For Grenouille, scent is life. Its preservation is his religion.

Grenouille goes through a different process of learning a ritual than Dexter does. Dexter’s father taught him who to kill, how to kill, and how to get away with it. Dexter kills “bad people” as a survival technique. His traumatic childhood leaves him incapable of fighting off homicidal urges, and his cop foster father figures that the best way to keep Dexter out of trouble is to teach him a way to channel those homicidal tendencies against people whose sinister transgressions will not be missed by society. Dexter’s first attempt at a ritualistic homicide mirrors Grenouille’s first attempt; it’s messy, and it borderline just does not work. Grenouille hires a prostitute to let him perform enfleurage, but she freaks out and he murders her. Dexter’s is a little bit different; he doesn’t have complete control over the situation and ends up having to chase his prey around a living room covered in plastic sheets. As Dexter matures and becomes more of an expert at his dastardly trade, he perfects his system. However, sometimes the belief of perfection in one’s system can prove to be a pitfall, because one may overlook evidence left behind. This occurs several times throughout seasons of Dexter and requires extra side work that detracts from the amount of attention he is able to give his day job, his family, and his girlfriend/fiancé/wife (depending on what season you are watching). For each kill, Dexter covers an entire room in plastic sheets, covers the wall in pictures of the perpetrators victims, toys with their mind, cuts their cheek to take a blood sample, and then impales them. He dismembers their bodies and then dumps them in the ocean, sinking to where nobody would dare find them. Dexter takes a token from each victim as a reminder of what he has done to benefit society, but also because it benefits himself. The blood slides are sacred to him because they are tangible proof of what he really is, lest he ever lose touch with himself. Similarly, Grenouille’s tokens are the essential oils he extracts from his victims. The essential oils serve a different purpose than the blood slides, but the keepsakes indicate that ritualistic murder does not stop at the ritual itself. Something must be taken because having a part of somebody else is a source of power for both Dexter and Grenouille.
The main idea here is that while both Dexter and Jean-Baptiste Grenouille are naturally inclined and pre-destined to be murderers, their discovery of ritual and the consistent following of said ritual are what give the serial killers strength in order to combat an inherent weakness. While both characters do not kill for the same reasons, they both engage in ritualistic behavior in order to give a chaotic, traumatizing life some semblance of meaning and order in a world that seems unfair, unjust and incompetent in solving its own problems.
