The Thursday Murder Club Ending Explained: Who the Killers Are and Why

Netflix’s adaptation of Richard Osman’s bestselling cosy crime novel The Thursday Murder Club has quickly become a global hit. But beyond the witty dialogue, quirky characters, and gentle humor, the show packs a finale filled with deception, shocking revelations, and heartbreaking truths. For those left reeling after the last episode, here’s a breakdown of who killed whom — and, perhaps more importantly, why.

Two Murders, Two Killers

Unlike many mysteries where one culprit ties all the threads together, The Thursday Murder Club keeps viewers guessing with not one, but two murderers revealed in the final act.

The first is Tony Curran, a ruthless figure tied up in shady dealings and intimidation. The second is Ian Ventham, an unscrupulous property developer desperate to cash in on the Coopers Chase retirement village. Their deaths — both violent, both shocking — form the backbone of the story’s climax.

But who killed them? The truth is as messy as life itself: two very different men, with very different motives, were responsible.

Bogdan and the Death of Tony Curran

The revelation that Bogdan, the enigmatic Polish handyman, killed Tony Curran is one of the finale’s biggest twists. It’s Elizabeth’s husband, Stephen, who first pieces it together. In a rare lucid moment, despite the fog of his dementia, Stephen recalls a conversation with Bogdan where the younger man confesses.

Years earlier, when Bogdan arrived in the UK, Tony took his passport — a classic move to trap vulnerable immigrants into dependency. Bogdan, effectively blackmailed, was unable to escape Tony’s grip. Their toxic relationship escalated until one day, after Tony attacked him, Bogdan fought back. The altercation ended fatally, with Bogdan killing Tony in self-defense.

Though he initially believes he has hidden the truth, Bogdan underestimates the sharp instincts of Elizabeth. She connects the dots after a conversation with Tony’s business partner, Bobby Tanner, and realizes Bogdan has been lying.

Elizabeth’s Race Against Time

The revelation about Bogdan puts Elizabeth in a dangerous position. With her husband vulnerable due to dementia, and Bogdan desperate to protect his secret, the tension mounts. Elizabeth rushes back to Coopers Chase, fearing Bogdan might silence Stephen to protect himself.

It’s a race against time, and it underscores one of the most poignant aspects of the series: the balance between frailty and resilience in old age. Stephen’s condition adds a heartbreaking layer to the drama, making the threat all the more real.

John Grey and the Fall of Ian Ventham

While Bogdan’s crime stems from personal survival, the second murder — of Ian Ventham — has more of a moral undertone. Ventham’s arrogance, greed, and willingness to destroy lives in pursuit of money made him one of the show’s most detestable characters.

His end comes at the hands of John Grey, a seemingly unassuming character whose motives catch everyone by surprise. Unlike Bogdan, John’s act is less about desperation and more about frustration with Ventham’s callousness and exploitation. His decision to kill Ventham isn’t a spur-of-the-moment fight but rather a calculated act driven by anger at Ventham’s relentless cruelty.

The duality between Bogdan and John’s killings — one accidental, the other deliberate — gives the finale its thematic punch.

The Role of the Thursday Murder Club

Throughout the series, the group of retirees — Elizabeth, Ron, Ibrahim, and Joyce — provide both comic relief and sharp insight. They poke fun at themselves, share meals, and reminisce about their lives, but beneath the lighthearted exterior lies a razor-sharp investigative instinct.

By the finale, it’s clear the group’s persistence is what forces the truth into the open. Without Elizabeth’s determination, Ibrahim’s logical clarity, and Ron’s blunt instincts, the double-killer ending might never have been uncovered.

Themes Beneath the Twists

Beyond the whodunnit mechanics, The Thursday Murder Club’s ending reflects Osman’s broader themes: the complexity of justice, the weight of moral compromise, and the resilience of those too often dismissed because of age.

Bogdan is not painted simply as a villain. His crime is born of exploitation and desperation, a reminder of the vulnerabilities faced by immigrants caught in cycles of abuse. John Grey’s killing of Ventham, meanwhile, is portrayed as a final stand against corruption and greed. Neither act is entirely justifiable, but neither is entirely unforgivable.

This moral ambiguity elevates the cosy mystery beyond caricature, offering audiences both closure and lingering unease.

Final Word

The ending of The Thursday Murder Club is quintessential Richard Osman: twisty, clever, and tinged with both humor and heartbreak. By revealing not one but two killers — Bogdan, in an act of survival, and John Grey, in an act of vengeance — the series delivers a finale that feels both satisfying and thought-provoking.

For Elizabeth, Ron, Joyce, and Ibrahim, the case’s conclusion reaffirms their unlikely role as truth-seekers in a world that too often overlooks them. And for viewers, the message is clear: murder may be messy, motives may be muddied, but justice can still be found — even in the most unlikely of places.
