TTK Original — Beyond the Headlines
Spoiler Warning: This article discusses major plot details and the ending of The Third Murder.
Two people are murdered in exactly the same way.
First, drug peddler Justin.
Then businessman Boban.
When police realize that the murders may be connected, DYSP Christy brings former police officer Swamy into the investigation. Swamy has experience dealing with serial killers, and the investigation eventually leads toward a troubled teenager named Aditya. BookMyShow
That creates the central question of The Third Murder:
Who is actually killing these people — and is Aditya really the killer?
The answer is deliberately more complicated than identifying a single suspicious character.
Because the movie is ultimately interested not only in who committed the murders, but in a more disturbing question:
What if even the person responsible cannot fully explain why the killings happened?
Why Do Justin and Boban’s Deaths Look Connected?
Justin’s murder initially appears to be an isolated crime.
That changes when Boban is killed.
The method resembles Justin’s murder closely enough for investigators to consider something much more dangerous:
They may be dealing with a serial killer.
This is why Boban’s death changes the entire investigation.
One murder can have a specific motive.
Two similar murders create a possible pattern.
And if investigators fail to understand that pattern before another victim is selected, there could be a third murder.
The film’s official synopsis explicitly builds its mystery around this escalation: Boban is murdered in the same manner as Justin, prompting Christy to bring Swamy into the investigation before another killing occurs. BookMyShow
Why Does Swamy Become So Important?
Christy is investigating the crimes as a police officer.
Swamy approaches them differently.
As a former officer familiar with serial-killer cases, he is interested in the behavior behind the crime.
That distinction matters.
Finding evidence can tell investigators what happened.
Finding a pattern may tell them what happens next.
Swamy therefore becomes crucial because the real danger is no longer merely solving Justin and Boban’s murders.
The investigators have to understand the killer quickly enough to prevent another one.
Why Does the Investigation Lead to Aditya?
Eventually, the trail leads toward Aditya, a troubled teenager whose difficult relationship with his eccentric father becomes increasingly important to the mystery. BookMyShow
This is where The Third Murder begins playing with the audience.
Aditya looks like the answer.
But mystery thrillers often use suspicion differently.
A character can be connected to the murders without the entire explanation being as simple as:
“Aditya is evil, therefore Aditya killed them.”
The movie wants us to understand the psychology surrounding the murders, not merely identify the person standing at the end of the evidence trail.
So Who Is the Killer in The Third Murder?
The film ultimately ties the killings to the person the investigation has been closing in on, but the reveal deliberately refuses to give viewers the kind of clean motive expected from a conventional serial-killer thriller.
That is the crucial point.
The mystery is not resolved by discovering a mastermind with an elaborate revenge plan.
Instead, the investigation exposes something far less comfortable:
the person responsible cannot provide a satisfying explanation for why the victims were chosen.
Even the film’s trailer foregrounded this idea before release, emphasizing that the accused himself does not know why the victims were killed. 사마칼리카 말라얄람
That transforms the meaning of the killer reveal.
Normally, learning the killer’s identity solves the mystery.
Here, it creates another one.
Why Doesn’t the Killer’s Identity Fully Solve the Case?
Imagine a conventional murder mystery.
The detective finds the murderer.
Then comes the explanation:
The victim betrayed him.
The victim stole money.
The killer wanted revenge.
The murder covered another crime.
Once motive and killer are connected, the audience feels that the puzzle is complete.
The Third Murder deliberately weakens that satisfaction.
The investigators can move closer to identifying the person responsible.
But identifying someone does not automatically explain that person’s mind.
That is why the movie is described not merely as a crime thriller but as a psychological thriller. Early audience coverage also emphasized the film’s slow-building suspense and psychological approach rather than treating it as a simple whodunit. Asianet News Malayalam
Is Aditya Simply a Villain?
That interpretation is too easy.
Aditya’s troubled family environment matters because the movie repeatedly pushes the audience away from a simple monster narrative.
His behavior cannot be separated completely from the psychological world surrounding him.
That does not erase responsibility.
But it changes the question.
Instead of asking only:
“Did he do it?”
the film asks:
“What happened inside this person before the murders happened?”
That is much harder to answer.
And unlike fingerprints, CCTV footage or physical evidence, psychology rarely produces a perfectly clean explanation.
Why Is the Third Murder So Important?
This is the one part we should not fully unpack here, because it deserves its own question.
But the basic mechanism is important for understanding the ending.
Justin’s death can be treated as one murder.
Boban’s death creates a possible pattern.
A third similar murder would transform suspicion into something much more frightening:
evidence that the killings are continuing.
So the investigation becomes a race.
Christy and Swamy are no longer trying only to explain the past.
They are trying to predict the future.
That is what gives the final part of the movie its tension.
The Real Twist Is Not the Killer
This may be the most important point in the ending.
The Third Murder appears to promise a familiar mystery:
Two similar murders.
One suspicious teenager.
Two investigators.
Find the killer before victim number three dies.
But the film gradually changes the puzzle.
The most disturbing mystery isn’t simply:
Who killed them?
It’s:
Why?
And when the person at the center of the killings cannot provide an explanation that makes everything fall neatly into place, the audience loses the comfort normally provided by a murder-mystery ending.
The police can identify responsibility.
They can reconstruct events.
They can stop another crime.
But none of that guarantees that they can fully understand the mind behind it.
The Third Murder Ending Explained
So the ending should not be read simply as a last-minute killer reveal.
The investigation leads toward Aditya and uncovers the person connected to the killings, but the deeper mystery survives the solution.
Knowing who committed a murder is not the same as knowing why that person became capable of murder.
That is why the film spends so much time on psychology, family conflict and Swamy’s attempts to understand behavioral patterns.
And it explains why the killer reveal may leave viewers with another question instead of complete closure.
The police are trying to prevent a third murder.
The audience is trying to understand the murderer.
Those sound like the same mystery.
By the ending, The Third Murder suggests that they are not.
