Summary
Marcella was not the killer of Grace, but she did move her body and had a connection to the case that she kept hidden.
Grace's step-brother Henry, driven by jealousy, was the actual perpetrator behind her murder, cunningly manipulating evidence to incriminate others for his crimes. Marcella's intricate and contradictory personality, marked by her occasional fugue states, contributed to the gripping enigma of the inaugural season, leaving lingering uncertainties about her true character.
Viewers during the first season of Marcella were left questioning whether Marcella had killed Grace. The answer was far from straightforward. The British TV series, inspired by Hans Rosenfeldt's distinctive Nordic Noir style, follows the titular detective, portrayed by Anna Friel, as she grapples with her personal struggles while attempting to solve gruesome murders. Throughout the entire season, Marcella herself becomes a prime suspect in the killing of a woman named Grace (Maeve Dermody), with all evidence pointing towards her.
Overall, Marcella received positive reception across its three seasons, adopting the crime-a-season format with a darker twist, incorporating the typical elements of Nordic Noir and its deliberately gloomy atmosphere. However, the show faced challenges due to long breaks between seasons, resulting in convoluted plotlines that occasionally suffered from unresolved issues. Despite the shifting directions taken in seasons 2 and 3, the gripping mystery of the first season established the show's overall tone. The takeaway from Marcella is that the eponymous character is a complex enigma.
Marcella Didn't Kill Grace (But She Moved Her Body)
Fortunately, Marcella was not the one responsible for Grace's murder, despite all indications pointing towards her. Throughout the series, Marcella kept certain details regarding her involvement in the case private, including the fact that she relocated Grace's body and that her husband had an affair with Grace. The season began with a chilling scene of Marcella covered in blood while sitting in a bathtub, and her tampering with CCTV footage suggested an attempt to conceal her own wrongdoing.
Eventually, it was revealed that Marcella had moved the body while experiencing a fugue state, a psychological state of disconnection that occurs during times of high stress. These episodes rendered Marcella prone to violent behavior, leaving the possibility that she could have snapped and murdered Grace due to the affair. Marcella's internal conflict added depth to the season, as it seemed she was hunting down a serial killer who could very well have been herself. In the final episode of season 1, it was disclosed that Marcella was not the killer, although her innocence was far from certain.
Henry Is Grace's Killer
The Nordic Noir genre often challenges the conventions of crime dramas, but the first season of Marcella concluded with a perplexing twist that was almost as unbelievable as Marcella's own fugue states that led to her predicament. Surprisingly, it was Grace's step-brother Henry (played by Harry Lloyd) who turned out to be her murderer, using the signature methods of a notorious serial killer to deceive investigators. However, Henry's attempt to frame someone else for his crimes ultimately failed, leading Marcella and her team on a relentless pursuit of the truth that ultimately led them to Henry.
As implausible as this revelation may be, the motivation behind Henry's actions was even more questionable. He killed Grace out of envy for the preferential treatment she received from their parents. Season 1 of Marcella also left certain aspects of the protagonist's character unresolved, as in a fugue state, Marcella almost killed Henry using the same suffocation technique that he employed on his victims. Though it can be interpreted as an act of revenge, it did not portray the heroine in the most heroic light.
