Plot Summary

Mia and Finn Hunter excitedly purchase a dilapidated Victorian house, envisioning it as the perfect place to start their family. Their excitement quickly turns to horror when Mia discovers a cryptic message etched into a skirting board: "I WILL SAVE THEM FROM THE ATTIC." This chilling discovery leads them to a hidden room in the attic, where they find seven small suitcases, each containing the mummified remains of a child. The shock of this discovery causes a pregnant Mia to fall from a ladder, resulting in the premature birth of their son, Sonny.

The ensuing police investigation reveals that the murders date back to the 1970s and 80s. The strain of the discovery, coupled with intense media attention and Sonny's fragile health, begins to fracture Mia and Finn's relationship. Suffering from PTSD, Mia becomes obsessed with the case and increasingly suspicious of her father-in-law, Dave Hunter, especially after learning he attended school with one of the victims. Her investigation leads her to a secret warehouse owned by Dave, where she uncovers forty more suitcases, each containing a child's body.

In a dramatic confrontation, Dave seemingly confesses to being the killer before taking his own life in front of Mia. The case appears closed, but the family's trauma is far from over. A tabloid exposes Finn's long-term affair and secret daughter, leading to his and Mia's separation. However, the true horror is yet to be revealed. Mia discovers video evidence that her mother-in-law, Debbie Hunter, deliberately shook the ladder, causing her fall. Further investigation, including a secret DNA test, reveals that Finn Hunter is not biologically related to Dave or Debbie.

The final confrontation exposes the ultimate truth: Debbie is the real serial killer, raised by murderous parents and continuing their legacy. Dave was her devoted, guilt-ridden enabler who protected her his entire life, ultimately sacrificing himself to preserve her secret. Finn was a baby she stole to replace her own deceased child. In a final, cruel act of revenge, Debbie kidnaps Sonny, leaving his fate terrifyingly ambiguous.

The Epilogue delivers the final, devastating twist. Two years later, it is revealed that Finn was not just a victim but Debbie's protégé. He was aware of her crimes and even participated in abductions as a child. He has murdered his uncle George Lewis to secure Sonny's return and is now secretly continuing the family's murderous legacy, all while manipulating Mia into a reconciliation, poised to create the perfect, deadly family unit he was raised to value.


Major Themes

The novel delves into complex themes that challenge our understanding of morality, identity, and the very definition of family. More information can be found on the Theme Overview page.

  • Family Secrets and Lies: This theme is the cornerstone of the novel, with every character concealing something significant. From Finn's affair to Dave's complicity and Debbie's identity as a killer, the narrative illustrates how secrets erode relationships and lead to catastrophic consequences.
  • Nature vs. Nurture: The book presents a dark exploration of this age-old debate. Debbie's evil is portrayed as a direct result of her horrific upbringing, while Finn, despite being stolen and raised by a killer, embraces her "nurture" to become a monster himself, raising unsettling questions about the influence of environment on behavior.
  • Manipulation and Control: Debbie is a master manipulator, controlling Dave through guilt and love, and attempting to control Mia and Finn's lives. This theme culminates in Finn's own manipulative efforts to rebuild his family with Mia, concealing his true nature and continuing the cycle of control.
  • The Past Haunting the Present: The discovery in the attic serves as a literal unearthing of the past, systematically destroying the present. Each character is a prisoner of their history, unable to escape the consequences of actions taken decades earlier, highlighting the enduring impact of past traumas and secrets.

Character Analysis

The characters in Keep It in the Family are intricately crafted to deceive the reader, with their true natures revealed in shocking layers. For a complete list, see the Character Overview page.

Mia Hunter: Initially the story's anchor and primary victim, Mia's journey is one of trauma, suspicion, and survival. She evolves from a determined renovator into a paranoid but perceptive investigator, ultimately becoming the only character to grasp the full scope of the Hunter family's evil, even if she remains unaware of her husband's true nature.

Finn Hunter: Finn's arc is a masterclass in misdirection. He begins as the supportive, if simple, husband, is revealed to be a flawed adulterer, and then appears to be a tragic victim of kidnapping. The epilogue recasts him as the book's ultimate villain—a cold, calculating killer who has fully embraced his dark upbringing.

Debbie Hunter: The novel's central antagonist, Debbie is the embodiment of evil disguised as maternal concern. Shaped by her own murderous parents, she is a prolific serial killer who uses manipulation and a facade of victimhood to control everyone around her. Her actions are driven by a twisted desire to "save" children and protect her family at any cost.

Dave Hunter: A deeply tragic and complex character, Dave spends his life as Debbie's enabler, his love for her overriding his moral compass. He is complicit in her crimes through his silence and assistance, and his final act—a false confession and suicide—is his ultimate sacrifice to protect the woman he both loves and fears.

"We all lie to protect the ones we love... You knew where I hid the diaries under your dad’s name – diaries that he agreed to me keeping – to protect me if I was ever caught. You should have honoured his memory and left them where they were. Not turned me in."

This quote from Debbie encapsulates the twisted logic and warped sense of loyalty that defines the Hunter family's relationships.


Literary Significance

Keep It in the Family stands as a significant contribution to the contemporary psychological thriller and domestic noir genres. John Marrs is known for his high-concept plots and relentless pacing, and this novel is arguably his most shocking. Its significance lies in its audacious use of plot twists, which not only surprise the reader but fundamentally reframe the entire narrative and character motivations multiple times.

The novel pushes the boundaries of the "secret in the house" trope to an extreme, creating a story that is both a gripping mystery and a dark exploration of intergenerational trauma. By making the final villain a character the reader has been led to sympathize with, Marrs subverts genre conventions and leaves a lasting, unsettling impression about the hidden nature of evil.


Historical and Cultural Context

Published in 2022, Keep It in the Family taps directly into the modern cultural zeitgeist's fascination with true crime. The narrative incorporates podcast transcripts, news articles, and police reports, mirroring the way real-life crimes are consumed by the public. This meta-commentary adds a layer of chilling realism to the story.

Furthermore, the novel preys on common contemporary anxieties: the financial and emotional stress of homeownership, the fear of not truly knowing one's partner, and the dark potential hidden within seemingly normal families. It reflects a cultural moment where the "perfect family" ideal is increasingly deconstructed in popular media, revealing the dysfunction that often lies beneath the surface.
