Summary
Jemma and Adam Spengler move to the Pacific Northwest seeking a fresh start. Their marriage is already fragile, strained by past tragedies and Adam’s infidelity. Jemma, once a promising dancer, is now a social media influencer clinging to the facade of a perfect life.
Adam, a highly respected oncologist, harbors dark secrets of his own. While their new home offers a chance to rebuild, it also exposes them—literally. With large open windows and an air of wealth, they attract attention, especially from their neighbor Chloe Cooper.
Chloe is an introverted, socially awkward woman who juggles multiple jobs while caring for her ailing mother, Raven.
Isolated and haunted by her past, Chloe has a peculiar habit—watching people from a distance, fabricating stories about their lives. She becomes fascinated by the Spenglers, particularly Jemma, whose glamorous lifestyle contrasts starkly with her own.
But Chloe’s world shatters when, one foggy morning, she witnesses a murder—a swimmer brutally killed on the shore.
As Chloe starts suspecting the Spenglers, their seemingly idyllic life unravels. Jemma, paranoid and sensing an ominous presence, grows increasingly anxious. Meanwhile, Adam is desperate to cover his tracks.
Unbeknownst to Jemma, he has already committed a crime—accidentally killing a woman, Marianne Wade, in a hit-and-run meant for his wife. Instead of going to the police, Jemma seizes the opportunity, using this knowledge to control Adam.
Their marriage, already fractured, transforms into a dangerous game of manipulation and power. Adam wants to escape with his mistress, art gallery owner Gloria Bergson, but Jemma refuses to let go.
When Gloria and Adam are later found brutally murdered at the Bergson Gallery, the police zero in on a suspect—Chloe.
Chloe, disoriented and covered in blood, remembers little from that night. Drugged and attacked by Adam, she fought back, but she doesn’t recall committing murder. Terrified, she flees, setting off a province-wide manhunt.
As the investigation deepens, shocking details about her past emerge. Chloe is not who she thought she was—she is the biological daughter of one of Canada’s most notorious serial killers, Robert “Abattoir” Autain.
Her mother, once his captive, had escaped and changed their identities. This revelation turns Chloe into a media spectacle, painting her as a woman with “killer’s blood.”
Meanwhile, Detective Maeve Havers isn’t convinced Chloe is the murderer. The evidence doesn’t quite add up, and inconsistencies in Jemma’s account raise suspicions. As cracks appear in Jemma’s carefully constructed story, her role in orchestrating the events becomes clear.
She manipulated Adam’s paranoia, knew about his affair, and subtly nudged events to ensure his downfall. The Bergson Gallery Murders were not a random act of violence—they were part of Jemma’s long game of revenge.
But even master manipulators can lose control. Jemma, having rid herself of Adam and Gloria, believes she has won. However, as detectives piece together the evidence, her lies unravel.
Years later, we see Jemma in a pitiful state—living in poverty, stripped of the wealth and power she once clung to. She no longer swims, the water now a symbol of her failures.
Chloe, though deeply scarred, finds a way to rebuild her life. She is no longer just a voyeur or the daughter of a serial killer, but a survivor who has endured an extraordinary ordeal.
Ultimately, The Swimmer is a chilling exploration of trauma, manipulation, and the devastating consequences of unchecked ambition. Every character is fighting their own demons, but in a world of deception, no one escapes unscathed.

Characters
Jemma Spengler
Jemma Spengler is a woman living with deep insecurities and a façade of perfection. On the outside, she is the glamorous wife of a wealthy surgeon, Adam Spengler, and seems to have everything she could want.
However, beneath the surface, she is grappling with a multitude of issues that have affected her marriage and sense of self. Jemma’s transformation from a once-promising dancer to a woman stuck in a deteriorating marriage speaks to her internal turmoil.
Her need for control and validation, as well as her insecurities about her relationship with Adam, propel her into a psychological battle of manipulation. Throughout the novel, Jemma’s ability to manipulate others is revealed as a key feature of her character.
She uses her knowledge of Adam’s infidelity and deceit to orchestrate a series of tragic events that ultimately spiral out of control. Despite her calculated vengeance, Jemma’s life unravels in the end, and her fall from grace serves as a reminder of the destructive nature of obsession and revenge.
Adam Spengler
Adam Spengler is a man whose polished, professional exterior hides a far more sinister side. A respected oncologist, Adam’s life seems ideal, but the cracks in his marriage to Jemma begin to show as his affair with Gloria Bergson, an art gallery owner, becomes known.
Adam’s character is shaped by his infidelity, his apparent lack of remorse, and his growing disillusionment with his wife. As the novel progresses, his actions become more extreme, culminating in the accidental death of an innocent woman in a hit-and-run that he had planned for Jemma.
This act of violence sets off a chain of events that exposes Adam’s true nature—he is not just an unfaithful husband but a cold-blooded murderer. His inability to take responsibility for his actions, combined with his desperation to secure a future with Gloria, drives him to make increasingly reckless decisions.
Adam’s character illustrates the themes of moral decay and the lengths to which a person will go to maintain control and cover up their sins.
Chloe Cooper
Chloe Cooper is a complex and deeply troubled character whose life has been shaped by trauma and a complicated relationship with her mother. Initially presented as a socially awkward woman, Chloe’s quiet existence as a dog walker and bartender masks a darker side to her past.
She is a voyeur who spends her days watching the lives of her neighbors, crafting stories about them from the safety of her home. Chloe’s character becomes more intricate as the story unfolds, revealing her connection to the notorious serial killer Robert “Abattoir” Autain.
This revelation shifts the reader’s perception of Chloe from a potential victim to a person with a deeply troubled legacy. Her attempts to distance herself from the shadow of her past are complicated when she becomes embroiled in the murders surrounding the Bergson Gallery.
Although she is framed for the crime, her story highlights themes of identity, trauma, and survival. Chloe’s journey is one of self-discovery, as she grapples with the truth of her origins while attempting to rebuild her life amidst the chaos that surrounds her.
Raven Cooper
Raven Cooper, Chloe’s mother, is a significant yet somewhat mysterious character in the story. She has been protective of Chloe her entire life, which is partly because of her own traumatic past.
Raven is revealed to be the mother of a child conceived during her captivity by Robert Autain, and she reinvented herself after escaping him. Her relationship with Chloe is marked by overprotectiveness and emotional control, suggesting that Raven may have been compensating for her own feelings of powerlessness.
Raven’s role is essential in understanding Chloe’s complicated identity and sense of self, as she has played a significant part in shaping Chloe’s worldview and fears. Raven’s death forces Chloe to confront the truths about her past, making it a pivotal moment in Chloe’s emotional journey.
Gloria Bergson
Gloria Bergson is another key character in the story who, while appearing to be an art gallery owner, is embroiled in the complex web of deceit and manipulation. She is revealed to be Adam’s mistress, and her relationship with him is one of secrecy and desire.
Gloria’s motivations seem to be driven by a need for validation and a desire to be part of Adam’s world, but she also becomes a victim of his violent tendencies. Her role in the story escalates when she is murdered, and her death plays a significant role in the psychological and physical unraveling of the other characters.
Her death also serves as a catalyst for the chaotic events that follow. Gloria represents the collateral damage of Adam’s moral decline and Jemma’s manipulative strategies.
Detective Maeve Havers
Detective Maeve Havers is a relatively minor but crucial character in the novel. As the detective leading the investigation into the Bergson Gallery murders, Maeve becomes a key figure in the pursuit of truth.
Unlike the other characters, who are deeply entangled in lies and manipulation, Maeve represents the external force of justice. She remains steadfast and methodical in her investigation, piecing together the various clues that slowly reveal the complexities of the case.
Through Maeve’s perspective, the reader gets glimpses of the external forces at play, and her determination to uncover the truth ultimately exposes the inconsistencies in Jemma’s narrative. Maeve’s role is essential for uncovering the true nature of the crimes and ensuring that the dark secrets of the characters come to light.
Themes
The Complex Interplay of Identity, Trauma, and Inherited Legacy
One of the central themes in The Swimmer is the exploration of identity and the profound effect of trauma, particularly intergenerational trauma. Chloe Cooper, the protagonist, is deeply shaped by her traumatic past.
Her identity is intertwined with the horrifying truth about her lineage, as she is revealed to be the daughter of Robert “Abattoir” Autain, a notorious serial killer. This discovery forces Chloe to confront the brutal reality of her existence: not only has she been shaped by her mother’s overprotectiveness, but she also carries the weight of her father’s horrific actions.
The novel delves into how trauma, particularly of a generational nature, can influence one’s behavior and worldview, creating an unbreakable cycle of suffering. Chloe’s struggle with this inherited legacy of violence becomes a key element of her character’s psychological unraveling.
As Chloe faces the challenge of distinguishing her own identity from that of her notorious father, the novel questions how deeply one’s past—especially one’s bloodline—can define or confine them.
The Deceptive Nature of Appearances and the Illusion of Perfect Lives
The theme of deception and the illusion of perfection is intricately woven throughout The Swimmer, particularly through the character of Jemma Spengler. On the surface, Jemma appears to have it all—beauty, wealth, a successful husband, and a seemingly perfect life.
However, beneath this veneer lies a labyrinth of deception, insecurity, and hidden pain. Jemma’s life is marked by a fragile sense of self-worth, driven by her desire to maintain the image of a glamorous, flawless existence.
She is unable to confront the truth about her fractured marriage with Adam, her husband, and instead seeks to manipulate and control the situation. Her eventual descent into calculated vengeance is an expression of the extreme lengths one can go to maintain the illusion of control and perfection.
Similarly, Adam, despite his professional success, harbors dark secrets, including his affair with Gloria and his role in a murder. The novel suggests that the perfect facades people construct can mask not only personal flaws but also horrifying truths, leading to inevitable chaos once these facades begin to crack.
The Unseen Power Dynamics in Relationships and the Toxicity of Obsession
Another important theme in The Swimmer is the complex and toxic power dynamics within relationships. The marriage between Jemma and Adam is marred by deceit, manipulation, and a toxic obsession that ultimately leads to tragedy.
Adam, initially a well-respected oncologist, becomes consumed by his affair with Gloria and the suspicion that Jemma may have caused the death of their child, Jackson. His growing obsession with his wife’s alleged mental instability leads him to a series of dangerous actions, including the murder of an innocent woman in a hit-and-run.
This obsessive dynamic is mirrored in Chloe’s own interactions with Jemma, who manipulates Chloe into becoming a pawn in her revenge plot. The novel explores the darker aspects of human nature, where individuals are driven by power, control, and the need to maintain dominance in their relationships.
As these toxic power plays unfold, the characters are drawn deeper into a web of manipulation, violence, and ultimately, their own undoing.
The Destructive Path of Revenge and Its Consequences on the Perpetrator
In The Swimmer, revenge is portrayed as a destructive force that not only harms the intended victim but also irrevocably damages the perpetrator. Jemma’s quest for revenge against her husband Adam for his infidelity and betrayal sets the narrative in motion.
However, Jemma’s method of seeking justice through manipulation and murder leads her to a place of psychological disintegration. As she orchestrates the deaths of Adam and his lover Gloria, she positions herself as the ultimate avenger.
However, as her plans unfold, the novel shows that revenge doesn’t bring the satisfaction or healing she seeks. Instead, it isolates her, leaving her to live in squalor and anxiety.
Jemma’s ultimate downfall—her loss of control over her own narrative—illustrates the point that revenge, while initially empowering, ultimately consumes the avenger, robbing them of their own peace and humanity. The novel suggests that revenge may provide temporary satisfaction, but it comes at the cost of one’s own moral compass and emotional stability, leaving the perpetrator haunted by the very actions they took to secure their vengeance.
The Psychological Toll of Deception, Manipulation, and Betrayal
The Swimmer intricately examines the psychological toll of deception, manipulation, and betrayal on both the victims and perpetrators. As Jemma manipulates Chloe and uses her as a pawn in her revenge scheme, the consequences of these actions begin to weigh heavily on both women.
Chloe’s mental state deteriorates as she grapples with the idea of being framed for a crime she doesn’t remember committing, while Jemma’s manipulative schemes unravel as her grasp on reality weakens. Adam, too, becomes a victim of his own lies and manipulations, ultimately descending into a murderous path as he tries to eliminate the evidence of his infidelity and his own guilt.
The novel offers a chilling portrayal of how these behaviors warp the minds of those involved, pushing them to commit actions that would otherwise be unthinkable. It explores how betrayal, when it is concealed under layers of lies and manipulation, can have a corrosive effect on the psyche, leaving lasting scars that can never be fully healed.
The Illusion of Control and the Chaos It Breeds in Human Lives
Finally, The Swimmer delves into the theme of control and the illusory nature of it. The characters, especially Jemma and Adam, attempt to maintain control over their lives through manipulation, lies, and calculated actions.
Jemma believes that she can control her situation by orchestrating the downfall of her husband and his mistress. Adam believes he can cover up his actions and manipulate his wife’s mental state to avoid facing the truth about his affair.
However, their attempts to control the events around them only serve to spiral their lives into greater chaos. The novel shows that the harder individuals try to control their circumstances and the people around them, the more uncontrollable their lives become.
Ultimately, the characters’ misguided attempts to exert power over others result in their downfall, underscoring the idea that control is an illusion and that life, when tampered with too much, often leads to destructive consequences.
