When You Disappeared by John Marrs is a gripping tale about the unraveling of a family’s life after a sudden disappearance. The story primarily follows Simon and Catherine, whose lives are torn apart when Simon vanishes one day without a trace.
As Catherine grapples with the emotional and practical impact of his disappearance, Simon is on a journey of his own, dealing with the aftermath of his decision to abandon his family. The novel unfolds in two timelines: one in the present day when Simon reappears, and one 25 years earlier, recounting his escape from the life he once knew. Themes of love, betrayal, guilt, and the search for redemption shape the heart of this complex narrative.
Summary
The story begins with Simon returning to Northampton, the place he once called home, after twenty-five years of absence. He arrives at the cottage where he and his family once lived, now a stranger to his past.
As Simon walks around the house, memories of his former life come flooding back. The quiet town holds a mixture of comfort and pain, and Simon is here to face the consequences of abandoning his family all those years ago.
His return is not a simple one; it is the beginning of a tense and emotional reunion with his estranged wife, Catherine.
The narrative shifts to June 4th, 1990, when Catherine wakes up early to handle the chaos of family life. Her three young children are a handful, and their dog, Oscar, is becoming a nuisance.
Her husband, Simon, has been going for morning runs, but today, something feels off. He fails to return, and as the day wears on, Catherine’s anxiety grows.
With each hour, her concern for Simon deepens, especially as he does not answer her calls. She starts searching for him around the town, checking the places he usually visits, but finds no trace of him.
As the hours drag on, Catherine becomes more frantic, and by evening, the community joins in the search for Simon. The police, neighbors, and friends all comb the area, but no one can find him.
Catherine is left to deal with the unimaginable: her husband has vanished without a trace. She struggles with how to explain this to their children, all while feeling the heavy weight of uncertainty.
The search continues, but as night falls, Simon is still nowhere to be found.
Meanwhile, Simon is on a journey of his own. He reflects on his troubled marriage and the emotional toll it has taken on him.
Overwhelmed by the pain and sadness of his relationship with Catherine, Simon decides to leave everything behind. On June 5th, Simon embarks on a journey away from his life, walking through the countryside without a clear destination in mind.
He ends up at a small caravan park, where he experiences a strange sense of freedom. However, his past, especially his troubled relationship with his mother, Doreen, continues to haunt him, making it difficult to escape his inner turmoil.
As the days go by, Catherine’s search for Simon intensifies. She contacts hospitals, friends, and even considers involving the police.
The investigation deepens, but the more she searches, the more uncertain she becomes about Simon’s fate. The emotional toll of not knowing whether Simon is alive or dead begins to consume her.
The emotional landscape of their home shifts, and Catherine struggles to keep the family together while dealing with the heartache of her husband’s disappearance.
Simon, still wandering aimlessly, grapples with his feelings of guilt and despair. As he interacts with strangers and lives a simple, carefree life in the caravan park, he is unable to escape the constant reminders of his family.
The pain of his decision to leave is ever-present, but he is unable to reconcile his guilt with his desire to start over. As the days stretch on, Simon comes to a realization: the life he once knew is irreparably broken, and he must leave it behind, even if it means disappearing for good.
By June 6th, Catherine’s heartache deepens. The pain of Simon’s absence is unbearable, and she begins to question whether he will ever return.
The search for Simon continues, but with each passing day, her hope wanes. She finds herself facing the harsh reality that Simon may be gone forever.
As the days drag on, Catherine’s sense of loss becomes more profound. She recalls happy memories of their life together, but the emptiness left by Simon’s absence cannot be filled.
The investigation continues, but no new information emerges, leaving Catherine with more questions than answers. The weight of the unknown continues to press down on her, and she wonders if she will ever get the closure she so desperately needs.
The narrative alternates between Simon’s internal struggle and Catherine’s search for answers. As Simon reflects on his past, the reader learns about his emotional baggage, including his relationship with his parents and his feelings of inadequacy.
These unresolved issues played a role in his decision to abandon his family. Meanwhile, Catherine struggles to maintain hope, desperately trying to understand what happened to Simon and why he disappeared.
In the present day, Simon finally returns to Catherine after a long absence. The reunion is filled with tension and hostility.
Catherine demands to know where he has been for the last 25 years while she and their children suffered. Simon’s explanation for his actions is selfish and unremorseful.
He tells Catherine that he had to leave in order to survive and that he blocked out his past to move forward. His lack of regret shocks Catherine, who cannot fathom how Simon could so easily dismiss the years of pain he caused.
Their confrontation escalates, and Catherine’s anger boils over. She cannot understand how Simon could abandon his family and build a new life without ever looking back.
Simon’s emotional detachment leaves Catherine feeling betrayed and confused. As they sit in the house he once called home, Catherine reflects on the years she spent raising their children without him, facing financial difficulties and emotional strain.
Simon’s indifference to the suffering he caused her only deepens her sense of betrayal.
As Simon continues to explain his actions, his past begins to surface. He admits to his troubled relationship with his best friend, Dougie, and the deep-seated issues within himself that led to his decision to leave.
However, Simon remains reluctant to fully confront the damage he caused, both to his family and to himself.
The story ultimately ends with no clear resolution to Simon and Catherine’s fractured relationship. Catherine is left grappling with her feelings of anger, betrayal, and confusion, while Simon remains evasive and distant.
Their reunion, filled with unresolved emotions, leaves the reader uncertain about what the future holds for them. The novel explores the devastating effects of secrets, guilt, and emotional turmoil on a family, and how the weight of the past can never truly be escaped.

Characters
Simon
Simon is a deeply troubled character whose life is marked by a series of poor decisions, betrayals, and guilt. His journey begins with a drastic escape from his family, leaving behind his wife Catherine and their children.
Simon’s decision to disappear is driven by his intense emotional turmoil, particularly the dissatisfaction with his marriage and his inability to cope with the tragic death of his son, Billy. This abandonment marks the beginning of his self-imposed exile, which sees him moving from place to place, adopting a carefree lifestyle that stands in stark contrast to the responsibilities he abandoned.
Simon’s inability to face his past is a recurring theme throughout the novel. As he immerses himself in a new life in France, working in a hostel and building a new identity, he tries to distance himself from the pain and guilt that haunt him.
However, he cannot completely escape the memories of his former life, and these unresolved emotions continue to plague him. His return to Catherine after twenty-five years, however, is not the heartfelt reunion one might expect.
He remains distant, detached, and almost indifferent to the pain he caused. His explanations for his actions are self-centered, and he justifies his decisions by claiming he needed to survive, without truly acknowledging the devastation his disappearance caused.
Simon is a man running from his past, struggling with deep guilt and a broken psyche, unable to confront the real consequences of his actions.
Simon’s emotional state worsens as he confesses to a series of troubling acts, including the murder of Paula, a close friend of Catherine’s. His revelations only add layers to his complex character, revealing a man who has lost touch with morality and is driven by self-preservation.
Despite his attempts to rationalize his actions, Simon remains a tragic figure who cannot escape the emotional and psychological wreckage he has left behind. In the end, Simon’s journey is marked by his deteriorating mental health, guilt, and an overwhelming sense of isolation.
His eventual breakdown and tragic end signify the irreversible damage he has caused to himself and everyone around him.
Catherine
Catherine’s character is defined by resilience, pain, and a fierce determination to rebuild her life in the wake of Simon’s disappearance. When Simon vanishes, Catherine is left to manage the emotional and financial fallout of his sudden departure.
She becomes the sole provider and caregiver for their children, all while grappling with the mystery of his disappearance. Despite the overwhelming sense of abandonment, Catherine continues to maintain hope, but as the years pass, she struggles to understand Simon’s motives and the impact his absence has had on their family.
When Simon returns after twenty-five years, Catherine’s emotions are a mixture of anger, betrayal, and disbelief. She is deeply scarred by the years of uncertainty, raising their children on her own, and the emotional toll it has taken.
Her initial reaction to Simon is one of icy hostility, and she demands answers for his years of abandonment. As Simon explains his actions, Catherine becomes increasingly repulsed by his lack of remorse and his self-justifications.
She is confronted not only with the man who left her but with a stranger who has no understanding of the devastation his absence caused. Catherine’s internal struggle is palpable as she is forced to face her unresolved feelings for Simon, the man who once represented the center of her world but now seems unrecognizable.
Through the novel, Catherine is shown to have undergone significant personal growth. She has learned to survive without Simon, find new relationships, and slowly rebuild her life.
Her relationship with Dr. Edward Lewis, for example, provides her with the stability she craves after years of chaos.
However, when Simon returns, it complicates everything she has fought for. Catherine is left to grapple with the haunting questions of whether she can ever forgive Simon for his past actions and the emotional devastation he caused.
As the novel progresses, Catherine’s struggle is not just with Simon but with herself, as she reflects on her own capacity for forgiveness and healing.
Dougie
Dougie, Simon’s best friend, plays a significant but often overshadowed role in the story. His presence highlights the complexity of Simon’s relationships and the underlying tension that existed in Simon’s life before his disappearance.
Dougie’s betrayal, which is revealed later in the narrative, is a critical point in the unraveling of Simon and Catherine’s marriage. Dougie’s involvement with Catherine, in the context of Simon’s absence, further fuels the emotional distance between the couple.
His actions are not just a betrayal of Simon but also an act that exacerbates the fractures in Catherine’s already fragile emotional state. His relationship with Simon is a study in codependency and the unhealthy dynamics of their friendship, which ultimately contribute to Simon’s departure and the ensuing emotional wreckage.
Though Dougie is not the central character, his impact on the narrative is profound, as his actions reveal the deep betrayals and unresolved issues that Simon faces.
Billy
Billy, Simon and Catherine’s young son, plays a pivotal but tragic role in the narrative. His death is the emotional catalyst for Simon’s eventual breakdown and departure.
The drowning of Billy is a moment of immense grief that neither parent can fully recover from. Simon’s inability to save Billy from drowning is an act of negligence that he later comes to regret, but his guilt over the incident is overwhelming.
This tragedy amplifies the tension in Simon and Catherine’s already strained marriage, pushing Simon further into emotional withdrawal and Catherine into despair. Billy’s death becomes a symbol of the irreparable loss both parents endure and a key factor in the disintegration of their family.
Though Billy’s presence is felt more in the past, his loss casts a long shadow over Simon and Catherine, influencing their actions and emotions throughout the novel.
Paula
Paula’s role in the story is critical yet haunting. She is a close friend of Catherine’s and the victim of Simon’s violent actions.
Paula’s death adds a layer of horror to Simon’s character, revealing the extent of his descent into darkness. Catherine’s grief over Paula’s death is compounded by the revelation that Simon was responsible for it.
The shocking confession that Simon killed Paula forces Catherine to confront the man she thought she knew and challenges her ability to trust anyone, including herself. Paula’s death, and the subsequent cover-up, are key elements that fuel the emotional tension between Simon and Catherine, leading to their ultimate confrontation.
Paula’s life and death serve as a reminder of the secrets that have been buried within Simon’s past and the devastating consequences of his actions.
Luca
Luca, Simon’s son, is another character whose presence in the story reflects the consequences of Simon’s past decisions. His relationship with Simon is complicated, as Simon is estranged from his family.
The revelation that Luca idolizes James, who turns out to be Simon’s half-brother, is a moment of clarity for Simon. It highlights the fragmented nature of Simon’s family and his inability to connect with his children due to the emotional distance he has created.
Luca’s existence serves as a reminder of what Simon has lost, and the relationship between father and son remains strained throughout the novel, reflecting the broader theme of familial alienation.
Themes
Guilt and Redemption
Throughout When You Disappeared, guilt plays a central role in shaping the emotional landscapes of the characters, particularly Simon. His disappearance from his family was a deliberate act to escape a life filled with pain and unfulfilled responsibilities, but as he roams through his new life, guilt relentlessly haunts him.
His abandonment of Catherine and their children may have been a self-preserving decision at the time, but over the years, it comes to represent an unresolved emotional wound that Simon cannot escape. As Simon’s journey progresses, his internal conflict becomes evident, especially when he reflects on his past decisions and actions.
His guilt is not only rooted in abandoning his family but also in the dark actions he takes after his disappearance, including his involvement in the murder of Paula. Simon’s struggle to reconcile with his past reveals his deep need for redemption, yet his actions continue to create barriers between him and the possibility of true atonement.
On the other hand, Catherine’s guilt is more focused on her perceived failure to keep her family together. The loss of Simon, and later the tragic death of their son Billy, compels her to constantly question her role in the family’s collapse.
While Simon is consumed with guilt over his departure, Catherine’s guilt manifests in her inability to protect her children from the trauma of Simon’s disappearance and the subsequent upheaval in their lives. However, her eventual decision to move on with her life, especially after Simon’s return, illustrates her attempt to find some form of redemption, albeit one rooted in survival rather than reconciliation.
In the end, Simon’s quest for forgiveness is overshadowed by his inability to fully confront his past, while Catherine, though scarred, finds a way to rebuild without him, acknowledging that some things cannot be undone.
Betrayal and Emotional Abuse
Betrayal runs deep within the characters’ relationships in When You Disappeared, particularly between Simon and Catherine. Simon’s abandonment of his family is the ultimate betrayal, not only because of his physical disappearance but also due to the emotional void it left in the lives of those he left behind.
This act of betrayal is compounded by his confessions years later, including the shocking revelation that he murdered Paula, one of Catherine’s close friends. The betrayal is not just in his departure but in his willingness to distance himself from his past, turning a blind eye to the consequences of his actions.
This emotional abandonment impacts Catherine in a way that no physical absence ever could, as it forces her to face a reality in which her husband, the father of her children, no longer exists in any meaningful way.
Simon’s return after 25 years only exacerbates the emotional abuse Catherine has endured in his absence. As Simon reveals more about his actions, including his disregard for the pain he caused, Catherine is faced with the unshakable reality that the man she loved is not the man who stands before her.
The trust that was once the foundation of their marriage is destroyed, and Catherine’s internal turmoil reflects the emotional abuse of living in the shadow of Simon’s lies and betrayal. Even in the present, Simon’s lack of remorse and his self-centered attitude further alienate Catherine, reinforcing the emotional harm he inflicted during their years apart.
Despite the passage of time, the psychological scars left by Simon’s betrayal remain deep, and the emotional abuse continues to shape Catherine’s decisions and sense of self-worth.
Family and Loss
The themes of family and loss permeate every aspect of When You Disappeared, as both Simon and Catherine grapple with the disintegration of their family unit. Simon’s disappearance and the uncertainty it creates are profound acts of loss for Catherine and their children.
The emotional weight of Simon’s abandonment is further deepened by the trauma of Billy’s death, a tragic accident that shatters the family. The loss of their son not only heightens the grief they both experience but also strains an already fragile relationship, pushing Simon and Catherine to the brink.
In Simon’s case, his inability to cope with Billy’s death and his subsequent emotional withdrawal from the family highlight his failure to be the father and husband his family needed. The lingering grief from this tragedy affects every aspect of Simon’s life, and the overwhelming guilt he carries prevents him from fully healing or coming to terms with his actions.
For Catherine, the theme of family is inseparable from loss. As she navigates the aftermath of Simon’s disappearance, she struggles to hold onto a sense of normalcy for her children, despite the overwhelming emotional burden she bears.
The responsibility of raising their children alone while dealing with financial hardships and social stigma intensifies her sense of isolation. Over time, Catherine is forced to rebuild her life, but the emotional toll of loss remains ever-present.
The loss of Simon, and later the death of Billy, forces Catherine to confront the fragility of family bonds and the ways in which trauma can irrevocably alter relationships. Even in her attempts to move forward and find new love, the ghosts of her past linger, showing that the impact of family loss is not something that can be easily overcome.
Secrets and the Impact of the Past
The theme of secrets is crucial in When You Disappeared, as both Simon and Catherine grapple with hidden truths that have far-reaching consequences. Simon’s initial disappearance is shrouded in secrecy, and as the narrative unfolds, it becomes clear that his reasons for leaving were not just about escaping a suffocating life but also about concealing deeper emotional scars.
His refusal to confront his past, including the relationship with his mother and his violent actions, prevents him from ever achieving peace. The revelation of Simon’s crimes, including his involvement in the murder of Paula, marks a point of no return in his relationship with Catherine.
These secrets, when uncovered, serve not only as a catalyst for the collapse of their marriage but also as a stark reminder of how the past can haunt the present. Simon’s journey is marked by his efforts to escape his past, yet it is this very past that determines the course of his life and, ultimately, his downfall.
For Catherine, the impact of Simon’s secrets is equally damaging. She is left to contend with the emotional fallout of Simon’s absence, the mystery of why he left, and the gradual unraveling of the truth about his actions.
The secrets Simon kept from her – from his reasons for leaving to the dark truths about his past – force Catherine into a position where she must rebuild her life without the clarity of answers. She must learn to navigate the consequences of his disappearance, the guilt she feels for not being able to save their family, and the emotional scars left by the secrets Simon buried.
The tension between knowing the truth and living with the consequences of that truth underscores the emotional weight carried by both characters, who are forever tied to a past they cannot escape.
