Just as she is about to marry fellow Garda Macdara Flannery, a shocking discovery on a quiet farm turns their wedding day into a crime scene.

It’s a compelling mix of lighthearted village life and dark, decades-old mystery.

Summary 

As Murder on an Irish Farm opens, Siobhán O’Sullivan is moments away from marrying her partner, Macdara Flannery, in the quaint church of Kilbane. Her wedding preparations are interrupted when her brother James arrives in muddy panic, announcing that he’s found a human skeleton in the slurry pit of the barn Macdara had secretly purchased as a wedding gift.

The ceremony is postponed, and instead of vows, the couple shifts immediately into investigative mode. The skeleton, face-down and dressed in a suit, appears to have been buried there for decades.

The timing of the discovery is suspicious: it coincides with what would have been the wedding anniversary of Gladys Burns. She is a neighbor who claims the remains belong to her fiancé, Tommy Caffrey.

Tommy vanished fifty years ago on the day they were supposed to marry, leaving behind only a short, cryptic note. Now, the presence of his body forces everyone to reexamine what really happened that day.

Siobhán and Macdara begin interviewing those closest to Tommy and Gladys. There’s Gladys’s sister Linda, who had objected to the marriage, and Alan O’Leary, Gladys’s brother, who found the note back then.

There’s also Howard Dunn, Tommy’s former business partner, and Joseph, Gladys’s stepson, who appears uneasy around the Gardaí. Suspicion grows when it’s revealed that Tommy and Howard were supposed to open a snooker club with £30,000 in cash—the same money that vanished when Tommy did.

Complicating matters is the sudden reappearance of Rose, Gladys’s stepdaughter, with her trained hawk Charlie. James had seen the bird moments before finding the body.

A pair of falconry gloves matching Rose’s is found near the pit. Gladys even claims the cherry stains on her rolling pin are just that—until Charlie scratches Joseph and suggests that blood may have been on it.

Before they can make sense of these odd clues, tragedy strikes again. Alan is found dead—also in the slurry pit.

His body, unlike the skeleton below, is fresh, and the signs point to foul play. Two bodies in the same location hint at a cover-up and an increasingly desperate killer.

Siobhán begins to wonder whether Alan had known something important about Tommy’s death, something that cost him his life. As the investigation deepens, long-held grudges, buried guilt, and suppressed memories surface.

Linda is caught between loyalty and anger. Gladys begins acting erratically, even donning her old wedding gown and reenacting the day Tommy left her.

It becomes clear to Siobhán that this is not just about a man who walked away from a wedding—it’s about betrayal, power, and secrets kept for half a century. Pieces start falling into place when the investigators discover a hidden compartment in the barn containing moldy cash—the long-missing £30,000.

This new evidence clears Tommy of having stolen it, shifting the narrative entirely. Motives sharpen: if Tommy didn’t run away with the money, someone may have killed him to prevent him from using it.

Suspicion returns to Howard, who had the most to lose financially, and to Linda, whose bitterness ran deep. Siobhán and Macdara begin piecing together a timeline.

They trace who was on the farm the day Tommy vanished and who had access to the barn. New footprints, inconsistencies in alibis, and conflicting testimonies all bring them closer to uncovering the truth.

Yet even as the picture becomes clearer, what remains is the emotional weight of lives stalled by secrets, justice delayed, and relationships shattered by lies. Siobhán must decide how to handle the truth not just as a Garda, but as someone preparing to begin a new chapter of her life.

Characters

Siobhán O’Sullivan

Siobhán O’Sullivan is the protagonist and an astute Garda officer whose emotional and intellectual depth defines much of the novel’s momentum. At the outset, she is a bride-to-be, caught in the intersection between personal joy and professional duty when a gruesome discovery postpones her wedding.

Throughout the investigation, Siobhán demonstrates a keen analytical mind balanced by emotional intelligence. Her ability to read people, draw connections, and pursue truth—despite personal cost—illustrates her commitment to justice and morality.

The emotional conflict she feels over Gladys’s eventual confession shows her nuanced sense of empathy. She is not just interested in catching criminals but in understanding their motivations and the web of history, pain, and repression that leads to violent acts.

Siobhán’s character arc is also marked by growth. She evolves from a woman preparing for marriage to one who wrestles with the psychological complexities of human relationships while solving a decades-old murder.

Macdara Flannery

Detective Sergeant Macdara Flannery is both Siobhán’s fiancé and her professional partner. Macdara is portrayed as steady, reliable, and deeply supportive of Siobhán.

His dual role in her life—romantic and investigative—adds layers to their relationship. It shows the tension between personal devotion and the impartiality demanded by police work.

Macdara’s thoughtful contributions to the investigation, especially his meticulous attention to forensic and circumstantial evidence, complement Siobhán’s intuition and emotional sensitivity. He is often the voice of calm and logic, grounding the more volatile emotional currents that emerge among the suspects and within Siobhán herself.

His commitment to truth and justice is mirrored by his enduring support for Siobhán. This culminates in their rescheduled and emotionally satisfying wedding.

Gladys Burns

Gladys Burns is a pivotal character whose outward eccentricities mask a dark and tormented history. Initially portrayed as a somewhat tragic figure—still mourning a fiancé who supposedly jilted her decades ago—Gladys exudes an unsettling mix of nostalgia, denial, and theatrical flair.

Her obsession with reenacting her failed wedding, complete with her aged dress and emotional dramatics, underscores her inability to move past her trauma. As the story unfolds, Gladys’s seemingly bizarre behavior takes on a sinister undertone.

The revelation that she murdered Tommy in a moment of betrayal-fueled rage alters everything. Her subsequent cover-up and the eventual murder of Alan to silence him highlight the extremes of her desperation to protect her constructed version of reality.

Gladys is both a victim of her own emotional repression and a perpetrator of violence. The novel treats her with a complex blend of sympathy and condemnation.

Alan O’Leary

Alan O’Leary serves as a tragic intermediary figure—neither fully villainous nor entirely innocent. Alan’s role in helping cover up Tommy’s murder reveals a long-standing burden of guilt.

His anxious and unstable demeanor before his own death suggests he had reached a breaking point. He may have been ready to confess or at least unburden himself.

Alan is depicted as a man who made a terrible choice out of loyalty, fear, or familial obligation. He then lived in the shadow of that decision for fifty years.

His murder—pushed into the same slurry pit that held Tommy’s remains—serves as a powerful metaphor. It reflects the inescapable consequences of guilt and the destructive nature of long-held secrets.

Linda

Linda, Gladys’s sister, is characterized by a blend of rigidity, moral superiority, and repressed emotion. Her initial hostility, particularly toward Tommy and the idea of her sister’s marriage, stems from her desire to protect Gladys.

It is also tinged with jealousy and control. Linda’s eventual emotional unraveling reveals the cost of maintaining appearances and suppressing truth.

She is not directly responsible for any deaths, but her silence, disapproval, and manipulations shaped the emotional landscape in which the murders occurred. Her confession about having seen key events and not intervening adds a layer of complicity.

Her character serves as a reminder that passive inaction can be as damaging as active wrongdoing.

Rose

Rose, Gladys’s stepdaughter, is introduced as a falconer and an initially suspicious figure due to circumstantial evidence. The presence of her hawk Charlie at the barn and falconry gloves found near Alan’s body draw police attention to her.

As the plot progresses, she is exonerated. Rose embodies a more modern, grounded character amidst a cast mired in past grievances.

Her knowledge of animals and detachment from family politics make her an observer more than a participant in the central drama. Ultimately, she emerges as a red herring, providing key pieces of the puzzle inadvertently but remaining untouched by the deeper emotional and criminal entanglements.

Joseph

Joseph, Gladys’s stepson, is a quiet and ambiguous character whose motivations are never entirely clear. His erratic behavior and possession of falconry equipment initially cast suspicion on him.

He turns out to be more of a red herring than a real suspect. Joseph seems shaped by a lifetime of living in the shadow of his complicated stepmother and a house haunted by secrets.

His subdued demeanor and lack of agency in the main events reflect the disempowering effects of growing up in a home where truth is silenced and dysfunction prevails.

Howard Dunn

Howard Dunn, Tommy’s former business partner, represents the theme of greed and misdirection. Early suspicions that he killed Tommy over the missing £30,000 frame him as a plausible villain.

As more information comes to light, it becomes apparent that Howard is likely a scapegoat. His connection to the money and business ambitions serves more to illuminate the economic motives behind the murder theory than to implicate him directly.

He adds complexity to the web of suspects. He underscores how financial ambitions and broken trust can corrode relationships.

Tommy Caffrey

Though long dead when the story begins, Tommy Caffrey’s presence looms large over the entire narrative. He is the ghost around whom all secrets revolve.

Initially believed to have jilted Gladys, the discovery of his murdered body upends the assumptions held for fifty years. As the investigation unfolds, Tommy is revealed not as a villain but as a conflicted man who may have wanted to escape a toxic relationship.

His tragic end—struck down while attempting to back out of a marriage—casts him as a victim of societal pressure and Gladys’s possessive delusion. The eventual discovery of the hidden cash he never took affirms his innocence.

This adds a posthumous dignity to his character. Tommy becomes a symbol of truth obscured by misunderstanding and silence.

Themes  

The Destructive Power of Long-Held Secrets

Murder on an Irish Farm talks about the corrosive effect of secrets—particularly those buried for decades. The narrative begins with the shocking revelation of a skeleton found on what was supposed to be Siobhán and Macdara’s wedding day.

This immediate disruption of joy underscores how long-buried truths can emerge without warning and change the course of people’s lives. As the investigation proceeds, it becomes evident that the past was carefully manipulated and concealed by those who had much to lose if the truth surfaced.

Gladys’s secret—that she killed Tommy in a moment of rage and allowed her brother Alan to help cover it up—demonstrates how secrecy can entangle guilt and loyalty into a toxic legacy. The concealment leads not only to the corruption of justice but also to Alan’s eventual death, as his complicity weighs heavily on his conscience.

The layers of lies told by multiple characters further illustrate that secrets, while seemingly dormant, often influence the present in dangerous and unpredictable ways. The emotional toll on the community and the O’Sullivan family is palpable, as trust is eroded and longstanding assumptions are shattered.

This theme ultimately asserts that time does not dilute the weight of truth. The refusal to confront it can prolong and amplify the consequences.

Justice Delayed and the Pursuit of Closure

The novel highlights the complicated nature of justice—especially when crimes go unresolved for decades. Tommy’s murder, which occurred fifty years before the story’s present, remained unsolved due to both deliberate concealment and the limitations of the justice system at the time.

The discovery of his remains reopens the question of justice—not only in the legal sense but also in terms of emotional closure for the people involved. Siobhán’s determined investigation reflects the modern pursuit of accountability, where long-ignored crimes are brought to light despite time’s passage.

The unearthing of Tommy’s body, the exposure of financial motives, and the confession that finally comes from Gladys all indicate that justice, though delayed, is not unreachable. However, the narrative complicates this idea by exploring the psychological impact of delayed truth.

For some, such as Gladys, the pursuit of justice forces a reckoning with actions long rationalized or suppressed. For others, like Rose and the rest of the village, the process restores faith in fairness and resolution.

The legal ramifications of the case, including Gladys’s arrest, may provide technical closure, but the emotional healing varies by individual. The novel suggests that justice isn’t simply about punishment but about truth, and until that truth is revealed, healing cannot begin.

Closure is not delivered solely through legal processes. It comes through the communal acknowledgment of wrongdoing and the reassessment of the past.

Family Loyalty and the Complexity of Relationships

The novel explores familial bonds—how they can offer both solace and conflict. Siobhán’s relationship with her siblings, particularly her protective instincts and emotional reliance on them, reflects a foundational layer of support that shapes her resilience and intuition.

In contrast, the other central family—the O’Learys and their extended relations—embodies how loyalty can become perverted in the service of self-preservation. Alan’s role in covering up Tommy’s murder for Gladys speaks to a twisted form of familial protection, where doing what seems necessary for a loved one leads to personal ruination.

Linda’s jealousy and disapproval of her sister’s engagement to Tommy show how family tensions can fester and contribute to tragedy. Joseph’s ambiguous presence throughout the investigation, including moments of suspicion and secrecy, further complicates the notion that familial ties guarantee honesty or moral behavior.

The dual nature of family—as a haven and as a source of suppression and control—is revealed repeatedly through these intergenerational dynamics. Siobhán herself must learn to navigate these nuances, especially as she tries to keep her personal and professional lives from colliding while investigating people who have long been part of her social fabric.

Ultimately, the book argues that family can inspire both the best and worst in people. True strength lies in choosing integrity over blind allegiance.

The Collision Between the Past and Present

There is a persistent clash between the past and the present, where unresolved histories continue to influence current events. The physical setting—the barn that Macdara bought as a surprise wedding gift—serves as a literal and symbolic burial ground for secrets.

As the story unfolds, past relationships, betrayals, and emotional wounds rise to the surface, forcing characters to confront things they believed were long forgotten or safely hidden. Gladys’s obsession with reliving her aborted wedding day—donning the same dress, mimicking rituals, and spiraling into emotional instability—exemplifies how the past can exert a near-possessive force over a person’s psyche.

The presence of old relics, such as the snooker box with a false bottom and the deteriorated bills, highlights how the material remnants of past plans and crimes remain embedded in the present landscape. The investigation itself is a process of bringing the past forward into the light, requiring the community to re-evaluate memories and reframe long-held narratives.

Siobhán’s role as both a daughter of Kilbane and a professional detective allows her to interpret the past through a modern, justice-oriented lens. The tension between remembering and forgetting drives much of the interpersonal drama and illustrates that the past is not passive.

It demands resolution. The farm, by the end of the book, transitions from a place of haunting to one of healing, symbolizing the potential for transformation when truth is finally acknowledged.

Identity, Redemption, and Personal Growth

The arc of Murder on an Irish Farm is also a story of identity and transformation, particularly for Siobhán. She begins the novel on the cusp of a new personal identity as a wife, only for that moment to be interrupted by a confrontation with death and mystery.

This disruption propels her further into her professional identity as a Garda, demanding that she prioritize duty over personal joy. Her ability to maintain emotional clarity, empathize with suspects, and untangle complex motives shows a maturation in her sense of purpose and morality.

Gladys, meanwhile, represents a character who clung to a fixed identity—betrayed bride, eternal victim—only to be unmasked as both the perpetrator and the architect of her own narrative. Her eventual confession, while tragic, offers a twisted form of redemption—not in the moral sense, but in the acknowledgment of truth.

Rose, too, finds a kind of redemption when suspicion is lifted and her role is clarified, allowing her to step out from under the shadow of guilt by association. The community as a whole experiences a transformation, as secrets are unearthed and long-standing assumptions are replaced with uncomfortable truths.

Identity, in the novel, is not static. It is tested, reshaped, and earned through experience, reflection, and sometimes painful honesty.

The final wedding ceremony, quieter and more intimate, marks not just a new chapter for Siobhán and Macdara but also a statement about the kind of grounded, transparent identity they wish to build going forward.
