There is something about a small town that crime drama understands exceptionally well.
On the surface, it should feel safer. Fewer people, familiar streets, neighbours who recognise one another, the same café, the same shop, the same road home. There is usually a sense that life moves more slowly and that very little happens without somebody noticing.
Then somebody is murdered.
Suddenly all that familiarity becomes uncomfortable.
The neighbour who knows when you leave for work also knows when you came home last night. The person serving coffee may have gone to school with the victim. The police officer taking your statement may know your parents. Families have histories stretching back decades, and an argument that appears to have started yesterday may actually have begun twenty years earlier.
In a city, anonymity can hide people.
In a small town, familiarity can hide them instead.
That is why small towns make such extraordinarily good crime drama.
Everybody Knows Everybody — Until They Don’t
The phrase “everybody knows everybody” appears constantly in small-town crime drama, but the interesting part is usually how quickly it turns out not to be true.
People know the public version of one another.
They know who married whom, which family owns which business, who drinks too much, who left town and who came back. They know the old gossip and the stories everyone has agreed to repeat.
What they do not necessarily know is what happens behind closed doors.
And that is where crime drama enters.
A murder exposes the distance between knowing somebody and actually knowing them.
The apparently ordinary family has a secret. The respectable neighbour has been lying. The person everybody mistrusted turns out to be innocent, while someone who has been part of the community for decades suddenly becomes impossible to read.
The town remains the same size.
The map does not change.
But psychologically, everything expands.
La Forêt: When the Forest Is Bigger Than the Village
La Forêt is a wonderful example because the community feels small while the landscape around it feels enormous.
The Ardennes forest surrounds the characters with something much older and less controllable than the town itself. People may know one another, but beyond the houses and roads there is darkness, distance and enough space for someone — or something — to disappear.
That contrast is one of the reasons the setting works so well.
Socially, there is nowhere to hide.
Geographically, there is almost too much room to hide.
The forest becomes both beautiful and threatening. It separates people, conceals things and constantly reminds us how quickly the familiar can become unknown.
And this is exactly where small-town crime becomes interesting. The village may appear contained, but the world immediately surrounding it is not.
Ardennes: Isolation Without Complete Isolation
Ardennes is particularly suited to crime drama because they offer a different sort of remoteness.
This is not necessarily the absolute isolation of an Icelandic settlement cut off by weather. Roads still lead somewhere. Other towns exist nearby. Life continues.
And yet there is enough forest, distance and quiet to create the feeling that a community can develop its own internal rules.
That matters.
The more self-contained a place feels, the more important reputation becomes. People remember families. They remember old incidents. They remember who belonged and who did not.
Sometimes they remember too much.
Sometimes they collectively remember the wrong version.
And sometimes an entire community appears to have quietly agreed that one particular subject is simply not discussed.
Crime drama loves that kind of silence.
Blackwater: The Past Never Really Leaves
Blackwater uses remoteness in another way entirely.
Here, landscape, community and memory become tangled together. The geographical isolation gives the story room to breathe slowly, but it also allows the past to remain remarkably close.
That is one of the great advantages small communities give crime writers: time behaves differently in them.
In a large city, people move away. Buildings disappear. Neighbours change. Entire streets can become unrecognisable within a generation.
In smaller communities, the person connected to something that happened decades ago may still be living a few doors away.
The old house may still be there.
The road may barely have changed.
The landscape certainly remembers nothing — but the people do.
That makes old crimes particularly powerful in small-town settings. The past is not somewhere else.
It is sitting across the table.
Le Voyageur: The Outsider Arrives
Le Voyageur gives us one of my favourite versions of the small-town crime story: the detective who arrives from somewhere else.
The whole idea of the series works beautifully for this. The investigator travels into communities across France carrying very little history of his own with him, while everyone he meets seems to be carrying years of it. He does not know which families have fallen out, whose reputation was destroyed twenty years ago, who is considered strange, who everyone trusts or which subject makes an entire village suddenly uncomfortable.
And that is precisely his advantage.
The locals know too much. He knows nothing.
He can look at the person everybody has decided is guilty without inheriting their assumptions. He can ask the question nobody local thinks needs asking. He can notice a relationship that has become so ordinary to everyone else that they no longer really see it.
I particularly love how Le Voyageur moves us through different parts of France rather than giving its detective one permanent territory. Each new investigation means entering another community, another landscape and another collection of old connections. The detective may change location, but the pattern is wonderfully familiar: arrive somewhere quiet, start asking questions and gradually discover that the small place in front of you is considerably more complicated than it first appeared.
It also gives us that wonderful small-town reaction to a stranger. Who is he? Why is he here? Why is he asking about something that happened years ago?
In a city, his arrival might barely be noticed. In a small community, the outsider himself becomes an event.
And perhaps that is why he can uncover things. He has no place in the local version of the story yet, so he is free to question it.
Distance Changes an Investigation
Small-town crime drama also changes the practical mechanics of solving a crime.
A detective in a city has thousands or millions of people around them. CCTV, public transport, crowds and constant movement create one kind of investigation.
A rural or small-town detective works with a different map. There may only be a handful of roads. Everyone notices a strange vehicle.
A journey that looks short on a map may take an hour. There may be one petrol station, one bar, one hotel or one place where everybody eventually passes through.
That creates boundaries. If somebody entered the town, perhaps someone saw them. If somebody left, perhaps there are only two roads they could have taken.
And if nobody left at all?
Then the suspect may still be there.
That simple possibility creates enormous tension.
The Outsider Is Immediately Visible
Small-town crime drama also gives writers one of the genre’s most useful characters:
the outsider.
Someone arrives.
Everyone notices.
Perhaps they are a detective sent from somewhere else. Perhaps they are returning after years away. Perhaps they have moved there because they wanted a quieter life — which in crime drama is usually a very dangerous ambition.
The outsider notices things locals have stopped seeing. But the locals know things the outsider cannot understand. That tension is endlessly useful. The outsider asks why everyone behaves strangely around a particular family.
The locals cannot understand why the outsider is asking.
The outsider sees an inconsistency. The locals see history. Neither perspective is necessarily complete.
And Then There Is the Person Who Never Left
The opposite character can be just as interesting.
The local detective.
This is something The Sommerdahl Murders understands particularly well. Dan Sommerdahl never feels like somebody temporarily assigned to Helsingør. He feels rooted there. He knows the streets, the people and the rhythms of the place.
When he investigates, he is not entering somebody else’s community. He is investigating his own. That changes everything.
A witness may also be an acquaintance. A suspect may be someone he has known socially. A victim may be connected to people he sees every week.
Professional distance becomes much harder when the geography of the case overlaps with the geography of your own life.
And because he belongs there, we believe that he understands things that would never appear in a police file.
Who dislikes whom. Which family has always been difficult. Who is pretending not to know somebody. Where people go when they want not to be seen.
That is local knowledge, and small-town crime drama can turn it into evidence.
Small Towns Remember
Memory may be the most important ingredient of all. Small communities remember who your parents were. They remember what happened when you were sixteen. They remember who left suddenly. They remember who was blamed. They remember the family nobody talks about anymore.
Sometimes that collective memory helps solve the crime. Sometimes it prevents anyone from seeing the truth. Because communities do not only preserve facts. They preserve versions of events.
A story is repeated often enough and eventually it becomes accepted history.
Crime drama can then arrive years later and ask the most dangerous possible question:
What if everyone remembers it wrong?
A Beautiful Place Can Become Claustrophobic
There is another contradiction I love.
Small-town crime dramas are often filmed in extraordinarily beautiful places: forests, lakes, coastlines, mountains, villages surrounded by open countryside. Visually, everything suggests space. Emotionally, there is none.
You can see for miles, yet everyone knows where you have been. You can walk into the forest, yet the moment you return somebody will probably notice. The landscape promises freedom while the community creates claustrophobia.
That tension is one of the reasons places such as the Ardennes or the remote landscapes of Blackwater work so effectively.
The setting is open. The social world is not.
Secrets Become Community Property
In cities, people can live remarkably separate lives. You may not know the person living two doors away.
Small communities operate differently. A secret rarely belongs to only one person. Someone saw something. Someone was told. Someone suspected.Someone decided not to ask. That last person is often the most interesting. Because small-town crime drama is rarely only about the person who committed the crime.
It is also about everyone who helped create the conditions in which the truth could remain hidden. Sometimes deliberately. Sometimes simply because admitting the truth would require admitting something uncomfortable about the community itself.
The Local Café Knows Everything
I have developed a particular affection for cafés, bars and restaurants in small-town crime dramas. They often function almost like unofficial police databases. No wonder that every DCI I see on an UK based tv series visits the local pub more than the police station.
Everyone passes through. Someone knows who was drinking with whom. Someone noticed that a person looked upset. Someone remembers a stranger asking for directions.Someone says they heard nothing — while clearly having heard absolutely everything.
These ordinary communal spaces make the fictional town feel alive. And they remind us that information moves differently in small places.
News does not need an official channel.
It crosses a counter with a cup of coffee.
There Is Nowhere to Start Again
Perhaps the darkest aspect of the small-town setting is that people cannot easily escape their own history.
In a city, you can change neighbourhoods.
Change jobs. Find new friends. Become somebody slightly different.
In a small community, everyone already knows the earlier version of you. That can create loyalty and belonging. It can also become suffocating. The person who made one mistake twenty years ago may still be defined by it. The family associated with an old scandal may never completely escape it.The child of somebody notorious grows up surrounded by people who remember the parent.
Crime drama understands how dangerous that can become.
Small Places Make Crimes Feel Bigger
Perhaps that is the simplest reason these settings work.
A crime in a small community feels enormous.
It changes the atmosphere of the entire place. People lock doors they never used to lock. Neighbours begin watching one another differently. Parents become nervous. Old suspicions return.
The familiar suddenly becomes threatening. And because the community is small enough for us to understand its shape, we feel that change. By the end of a good small-town crime drama, we know the roads. We recognise the café. We understand who lives near whom.
The map becomes intimate.
So when something disturbs it, we notice.
This Is Why I Keep Returning to Small Towns
I love cities in crime drama. They offer anonymity, complexity and endless layers.
But small towns offer something else.
They make crime personal.
La Forêt gives us a community sitting beside a forest large enough to conceal almost anything. The Ardennes create distance without completely removing civilisation. Blackwater shows how geography can preserve memory, while Broadchurch demonstrates how quickly one crime can pull an entire community into its orbit. Erica reminds us that ordinary places can contain extraordinary stories.
And then there are all the other villages, islands, coastal towns and remote communities scattered throughout crime television, each proving the same thing in a slightly different way.
The smaller the place becomes, the more significant every connection seems.
Who knows whom?
Who remembers what?
Who arrived?
Who left?
And perhaps most importantly:
who has been there all along?
