With Kellerman’s signature blend of forensic detail, psychological insight, and taut suspense, Open Season challenges readers to confront the shadowy realities lurking beneath the glitter of the entertainment industry and the complexities of vigilante justice.

Summary

The story begins with the discovery of a young woman’s lifeless body, abandoned outside a questionable hospital in Los Angeles. The victim, Marissa French, is a 25-year-old aspiring actress who had been working part-time caring for elderly patients.

Her death appears to be the result of a drug overdose, but something about the circumstances raises suspicion. LAPD detective Milo Sturgis, known for his sharp instincts and unconventional methods, teams up with Alex Delaware, a child psychologist with a knack for understanding the darkest corners of human behavior, to investigate.

Early clues point to a sleazy middle-aged man, Paul O’Brien, a failed stuntman whose life is marked by delusion and predatory behavior. Marissa was last seen in his company, dressed provocatively and possibly under the influence of drugs he administered.

As the detectives delve deeper, they uncover a disturbing picture of exploitation masked by the allure of Hollywood glamour. Marissa’s social circle, including several friends and acquaintances, describe her as optimistic but vulnerable, caught in a world where dreams often mask danger.

The investigation takes a sharp turn when O’Brien himself is found murdered on his balcony, complicating the case and raising questions about who might have sought retribution. Was O’Brien’s death linked directly to Marissa’s? Or did it stem from something even darker?

The detectives begin to unravel the layers of deceit, looking into O’Brien’s past as a stuntman and his connections within the industry. Meanwhile, evidence suggests that Marissa’s last days involved contact with a mysterious figure promising roles that may have been mere bait for exploitation.

As Milo and Alex follow the trail, they encounter a broader web of victims, suspects, and enablers. The investigation expands from a single tragic death into a pattern of violence targeting individuals connected to abuse and predation.

The discovery of other victims — all seemingly linked by the presence of a highly intelligent, methodical killer — shifts the tone of the inquiry from a straightforward homicide to a hunt for a serial murderer operating under a twisted moral code.

The killer, Cameron Flick, emerges as a central figure — a math prodigy with an unsettling god complex and a cold, calculated approach to murder. Using sniper precision and careful planning, Flick targets those he deems morally corrupt or harmful to the vulnerable.

His killings are not random but driven by a warped sense of justice, removing predators and those who have failed to protect victims. This vigilante-like rationale introduces complex ethical questions about the nature of justice and the psychology of punishment.

Delaware and Sturgis work tirelessly, piecing together Flick’s background, including his troubled childhood marked by abuse and social isolation. Through interviews, forensic evidence, and behavioral analysis, they reveal a man who views his murders as acts of mercy, rationalized with chilling detachment.

His ability to evade detection for years speaks to his meticulous planning and intellectual arrogance.

Throughout the investigation, the detectives confront the emotional toll of the case. Marissa’s story, alongside others affected by Flick’s actions, paints a grim portrait of ambition, exploitation, and survival in a world where the powerful prey on the vulnerable.

The novel explores themes of justice, morality, and the blurred lines between right and wrong, as the protagonists wrestle with their own sense of duty and the limitations of the legal system.

The narrative is richly layered with detailed procedural work, psychological insights, and a tense cat-and-mouse game between law enforcement and a killer who believes he is above the law.

The story also delves into the personal lives and struggles of the investigators, especially Alex Delaware, whose background in psychology offers a unique lens into the minds of both victim and perpetrator.

As the case unfolds, readers are drawn into a complex maze of motives and secrets, with multiple characters connected in unexpected ways.

The pursuit of truth becomes as much about confronting inner demons as about solving the crimes, making Open Season a compelling blend of thriller, mystery, and psychological drama.

Characters

Milo Sturgis

Detective Milo Sturgis stands out as a seasoned and pragmatic LAPD detective with a strong moral compass and a deep sense of justice. He is methodical in his investigations but also shows a compassionate side, especially toward victims like Marissa French.

Milo’s years on the force have given him a tough exterior, but he frequently collaborates with Alex Delaware, relying on Alex’s psychological insight to complement his police instincts. His approach to law enforcement balances skepticism with empathy, making him a grounded and trustworthy figure amid the chaos of the case.

Alex Delaware

Alex Delaware, a forensic psychologist, plays a critical role in unraveling the psychological complexities behind the crimes. His background in psychology allows him to analyze not just the suspects but the victims as well, providing insight into their motivations and vulnerabilities.

Alex is reflective and empathetic, often contemplating the broader societal factors contributing to the victims’ predicaments, such as exploitation and broken dreams. His partnership with Milo is based on mutual respect, and Alex’s intellectual and emotional depth brings a unique perspective to the investigation, especially when profiling the killer, Cameron Flick.

Paul O’Brien

Paul O’Brien, initially introduced as a failed stuntman, emerges as a deeply flawed character who preyed on young women like Marissa French. His background in Hollywood as a washed-up professional turned predator highlights the dark underbelly of the entertainment industry.

O’Brien is portrayed as manipulative and morally corrupt, using his connections and false promises to exploit vulnerable aspiring actresses. His murder complicates the investigation, raising questions about justice and vengeance in a world rife with exploitation.

Marissa French

Marissa French is a tragic figure whose story is central to the narrative’s emotional weight. She embodies youthful ambition and naivety, desperate to break into Hollywood but ensnared by predatory figures like O’Brien.

Marissa’s optimism contrasts sharply with the harsh reality she faces, and her death serves as a catalyst for the entire investigation. Through her interactions with friends and the investigation into her life, Marissa’s character evokes sympathy and highlights the vulnerabilities of those chasing dreams in a ruthless environment.

Cameron Flick

Cameron Flick, the antagonist, is portrayed as a cold, calculating, and highly intelligent killer whose actions blur the line between justice and vigilantism. A math prodigy with a troubled past marked by abuse and isolation, Flick justifies his sniper killings as a form of moral cleansing, targeting sexual predators and those who failed to protect victims.

His psychopathy is evident in his detached demeanor and strategic thinking. Flick’s belief in his intellectual superiority and his warped sense of justice drive the novel’s tension and moral ambiguity, making him both a terrifying villain and a complex character worthy of psychological study.

Petra Connor

Petra Connor, another LAPD detective, supports Milo and Alex in the investigation, bringing additional police rigor and dedication. She is pragmatic and competent, helping to navigate the procedural aspects of the case.

While not as deeply explored psychologically as the primary characters, Petra’s presence reinforces the teamwork dynamic within the police force and the collaborative nature of complex investigations.

Supporting Characters

Supporting characters such as Marissa’s friends—Yoli, Beth, Bethany, and Tori—add depth to Marissa’s backstory and emphasize the social networks that both nurture and expose vulnerable individuals to danger.

Their descriptions reveal the social environments that the victims inhabit, ranging from hopeful camaraderie to risky associations with predators disguised as helpers.

Themes

Vigilante Justice and Moral Ambiguity in the Pursuit of Retribution

Open Season talks about the exploration of vigilante justice through the character of Cameron Flick, whose actions blur the lines between justice and criminality. Flick’s meticulous, calculated murders of sexual predators and those who fail to protect victims raise difficult ethical questions about the nature of justice outside the law.

His rationale—removing “undesirables” as a form of moral cleansing—is steeped in a chilling cold logic, demonstrating how trauma and a god complex can warp an individual’s moral compass. The novel forces readers to confront the discomfort of sympathizing with a killer who targets reprehensible characters yet operates outside the bounds of societal rules.

It probes the tension between the desire for retributive justice and the dangers inherent in taking the law into one’s own hands. This highlights the thin and often subjective boundary between heroism and villainy.

Systemic Failures and Societal Complicity in Enabling Exploitation and the Victimization of the Vulnerable

A deeply unsettling theme running throughout Open Season is the exposure of systemic failures—particularly in Hollywood and law enforcement—that allow exploitation and abuse to persist. Through Marissa French’s tragic story, the novel critiques the predatory environment of show business, where naïve hopefuls are lured into dangerous situations by figures wielding power and deception.

Kellerman underscores how institutions often neglect or outright fail victims, whether through negligence, corruption, or willful blindness. The complicity of social systems that prioritize reputation, profit, or convenience over justice creates fertile ground for predators like Paul O’Brien to operate.

This theme resonates with contemporary conversations about abuse in entertainment industries, examining how ambition, manipulation, and power imbalances entrap vulnerable individuals. It compels readers to reflect on the broader societal responsibilities in protecting victims and holding perpetrators accountable.

Fragmented Human Psyche as a Battleground Between Trauma, Identity, and the Quest for Control

Another theme in Open Season is the psychological complexity of trauma and its role in shaping identity and behavior, especially as seen in both victims and perpetrators. Characters such as Cameron Flick embody the ways childhood abuse, social isolation, and unresolved trauma can manifest in dangerous, destructive ways.

Flick’s intellect and precision mask a deeply fractured psyche, revealing the paradox of a highly functional mind driven by profound emotional wounds and a desperate need for control. Likewise, Marissa and other victims’ struggles reflect the ways trauma undermines self-worth and distorts personal aspirations.

The narrative intricately explores how trauma fractures the human psyche into competing impulses of vulnerability, rage, hope, and despair. It portrays the internal battles that define much of human experience.

Through this lens, the novel delves into the limits of psychological resilience and the consequences when that resilience breaks down.

Intellectualism and Psychopathy

The portrayal of Cameron Flick as a math prodigy with a god complex in Open Season invites a nuanced examination of the dark intersections between high intellect and psychopathy. Kellerman probes the unsettling reality that cognitive brilliance does not equate to emotional empathy or ethical behavior.

Flick’s surgical precision and calculated murders illustrate how intellect divorced from moral engagement can be weaponized to devastating effect. His strategic manipulation of the legal system and calm, detached recounting of his crimes reveal a chilling dissociation from humanity.

This raises questions about the nature of evil when embodied in someone capable of understanding but indifferent to the suffering they cause. This theme interrogates assumptions about intelligence, morality, and the capacity for evil.

It suggests that intellectual gifts can amplify destructive tendencies when untethered from compassion and conscience.
