Behind every crime story worth its salt lies a single undeniable truth: for the protagonist, love is the foundation of every great crime drama— sometimes in the most unexpected ways.
You might not immediately think of love when you’re knee-deep in a heart-pounding thriller, but look closer. Love, in one of its many forms, is the force that drive the heroine to act, raises the stakes, fuels motivations, and adds emotional depth to crime stories. Whether it’s a detective obsessed with finding justice for a lost loved one, a criminal avenging a broken heart, or a family torn apart by betrayal, love is at the core of every crime story, turning what might be a simple mystery into an unforgettable story.
As a forensic specialist and crime writer, I’ve seen firsthand how different forms of love shape both real and fictional cases. In this post, I’ll break down the four core types of love—romantic, familial, platonic, and divine—and how they elevate crime dramas. Plus, we’ll analyze how Broadchurch expertly weaves these elements into its story and discuss how you can craft your own love-driven mysteries.
If you love crime fiction with forensic accuracy and deep emotional impact, you’re in the right place.
The Four Forms of Love in Crime Stories
In storytelling, love isn’t just about romance. It manifests in different ways, each adding unique emotional stakes to a crime narrative.
1. Romantic Love (Eros) – The Passion That Fuels the Fire
Romantic love is intense, consuming, and deeply personal. It’s the passion that can drive your protagonist(s) to the edge—sometimes leading them to greatness, other times to destruction.
Examples:
Castle – Rick Castle’s love for Kate Beckett fuels his commitment to solving crimes, even when it puts him in danger.
Bones – Dr. Brennan and Booth’s relationship balances intellect and emotion, making their crime-solving dynamic all the more engaging. We watch the series, (yes for the cool mystery elements,) but mostly to see how things will turn out between these two.
💡 Impact on Crime Stories:
Romantic love raises the stakes. It forces your protagonist to make impossible choices, blurs the line between justice and revenge, and often becomes the singular motive for your protagonist to act.
Want to deepen your crime story? Give your protagonist a love interest whose safety, betrayal, or death could change everything.
2. Familial Love (Storge) – The Bonds That Can’t Be Broken
The love between family members is often the strongest, most complicated, and most dangerous form of love. It’s unconditional, yet it can also be a source of devastating conflict.
📖 Examples:
Dexter – Dexter’s love for his sister, Debra, creates emotional turmoil, especially as his double life threatens her safety.
Peaky Blinders – The Shelby family’s fierce loyalty often leads them into dangerous, criminal activities.
💡 Impact on Crime Stories:
Familial love creates compelling motivations. A protagonist might risk everything to protect a family member—or seek vengeance when one is harmed. It also adds layers of internal conflict, as duty to family clashes with personal morality.
Writing tip: Explore how far your characters are willing to go to protect, avenge, or even betray their own blood. The bolder you go, the more suspense and tension you create.
3. Platonic Love (Philia) – The Unshakable Partnerships
Friendships and partnerships are the backbone of many great crime stories. These relationships are built on trust, loyalty, and often, unspoken sacrifices.
📖 Examples:
Sherlock – Holmes and Watson’s bond is the emotional core of their investigative brilliance.
True Detective – Rust Cohle and Marty Hart’s evolving friendship fuels the entire series.
💡 Impact on Crime Stories:
Platonic love adds emotional weight to detective duos and investigative protagonists. When one partner is in danger, the audience feels it. When trust is broken, it creates some of the best dramatic tension in storytelling.
Want to make your mystery stronger? Build a deep, complex friendship between your main characters—then test its limits. Is there a point at which one friend betrays the other? Is it for a their own personal good or self interest?
4. Divine Love (Agape) – The Pursuit of Truth & Justice
Some crime stories are driven by personal relationships with a higher being. Protagonists put this love above all others. This form of love manifests in protecting the object of that love. If your protagonist is driven by love for the divine, that embodies the values of truth, justice, and morality.
📖 Examples:
Blue Bloods – This family of cops, detectives and attorneys are centered in their love for God. That manifests in the way they play out their work life as investigators for justice and good.
Father Brown – A priest-turned-detective seeks truth with unwavering faith.
💡 Impact on Crime Stories:
This kind of love gives crime dramas spiritual, ethical, moral, and philosophical weight. Protagonists make hard moral choices based on their fidelity for God and all that God embodies. They want to emulate the values of God on earth. I.E. truth, beauty, goodness, justice, morality, virtues.
Writing tip: Ask yourself—what are the highest values or principles your protagonist die for? Love of country? Love of God? Love of truth and justice? The core of their story must be centered on protecting that.
Case Study: Broadchurch – A Masterclass in Love & Crime
Few crime dramas weave love into their storytelling as seamlessly as Broadchurch.
🔍 Ellie Miller’s Love for Her Community – Ellie is deeply invested in the town and its people, making her pursuit of justice for the murdered boy intensely personal. Her love for the greater good of the community is truly agape love.
❤️ Familial Devastation – Ellie is fiercely devoted to her husband and son. When Ellie’s husband is revealed as the killer, her world is shattered. Absolute betrayal! The show brilliantly explores how love can both heal and destroy.
👮 Platonic Partnership with DI Alec Hardy – Their strained yet evolving trust adds depth to the investigation.They will protect one another for the mutual love of justice and community.
📖 Lessons for Writers:
Layer different types of love to heighten emotional stakes.
Use love to challenge and test your characters—when trust is broken, everything changes.
If you haven’t watched Broadchurch, study it as a prime example of love driving crime fiction.
Crafting Love-Driven Crime Stories
Want to make your crime writing deeply engaging and emotionally resonant? Love—whether it’s romantic, familial, platonic, or divine—shouldn’t just be a subplot. It should drive decisions, increase stakes, and push characters to their limits.
Here’s how to seamlessly weave love into your crime narratives:
1. Start with Your Protagonist’s Love Story
Before you outline the crime, ask yourself: Who is your protagonist’s greatest love? Pro tip: It has to be a person. Not a thing. Someone tangible and real. If it’s divine, their love is for God above all others. What kind of love fuels them, and how does it shape their choices?
Romantic Love: Is there a forbidden relationship or a partner they’d do anything to protect?
Familial Love: Does their past with a parent, sibling, or child impact how they seek justice?
Platonic Love: Is there a deep, unwavering friendship that keeps them grounded?
Divine Love: Is their sense of morality or justice their guiding force?
💡 Example: In Sherlock Holmes, Watson’s unwavering loyalty to Sherlock is the emotional core of the series, making every case more than just an intellectual pursuit—it’s personal.
2. Build a Love Backstory
Love is rarely simple. Give your protagonist a rich history filled with relationships, betrayals, and losses that influence their present choices.
Consider:
A past love that ended in tragedy, leaving emotional scars.
A childhood relationship that shaped their understanding of loyalty. (A River Runs Through It)
A betrayal that makes them hesitant to trust again. (Monk)
💡 Example: In The Coroner’s Daughter, Emily Hartford’s love for her father (familial love) is complicated—she spent years running from their fractured relationship, yet she’s pulled back into his world when he falls ill. This personal conflict makes her return to forensic investigation all the more powerful. At its core, the whole series is a retelling of the Prodigal Son parable. As the parable teaches, I believe we all have an innate longing for home: that which is good, true, and beautiful. How far do we sometimes stray from it? And what will it take to bring us back home to that which is truly life-giving. Even if we don’t physically return to our hometowns, as Emily does, How do we work to align ourselves with what is good, true, and beautiful? How can you do that with your protagonist?
3. Let Love Shape the Stakes
Love should push your protagonist into difficult, high-risk decisions. Make them choose between duty and desire, justice and loyalty. The more tangled their emotions, the higher the tension.
Would your detective break the law to protect someone they love?
Would your protagonist risk everything for the truth, even if it meant hurting those closest to them?
Could love blind your heroine to the real danger in front of them?
💡 Example: In Broadchurch, Detective Ellie Miller’s love for her family collides with her duty when she learns her husband is the killer. Her personal and professional worlds crumble, making her struggle more gripping than the crime itself. Which love will she uphold in the end? Her familial love for husband? Or her agape love for community/justice?
4. Let Love Evolve Over Time
Love isn’t static. Let it grow, fall apart, or take unexpected turns as your story unfolds. But make sure that the love your protagonist is driven from at the core of the story, remains in tact.
A hardened detective might finally open up to love after years of solitude.
A close friendship could fracture under the pressure of a case.
A past romance might resurface at the worst possible moment.
💡 Example: At the core of the series Mindhunter, Holden Ford is driven by agape love. He wants to understand serial killers better so that they can be hunted down and stopped. He is driven by the divine to uncover truth and justice. In his personal life and relationships, however, he starts out detached from emotions, but as the series progresses, his relationships shift and unravel, making his descent into obsession all the more chilling.
Practical Tips for Writers: Weaving Love into Crime Stories
Love is at the heart of every gripping crime story, but showing it effectively—without making it cliché or overly sentimental—is where the real craft comes in. Below are actionable ways to integrate love into your crime narratives while keeping them realistic, compelling, and tension-filled.
Use Dialogue & Subtext to Show Love Without Over-Explaining It
In real life, love isn’t always spoken—it’s felt in small gestures, subtle expressions, and moments of sacrifice. The best crime writers know that showing love is far more powerful than telling it outright.
Example: Instead of having a detective say, “I love my partner like a brother,” show it through action:
She stays up all night investigating a case that’s personally tied to her partner, knowing neither will rest until they have answers.
She holds back anger when betrayed, giving her partner a second chance because of years of loyalty.
Crime Dramas That Nail This:
Mindhunter – Agents Holden Ford and Bill Tench rarely verbalize their care for each other, but their evolving trust is built through shared struggles. They stick together and believe in each other and the mission at hand.
Sicario – The tension between FBI agent Kate Macer and government operative Matt Graver is thick with unspoken trust and wariness. Not backing down in the face of danger sends a huge message.
Writing Tip: Show love through body language, tone shifts, protective actions, and sacrifices, rather than dumping emotions into dialogue.
Test Love in Moments of Crisis
Want to truly prove a protagonist’s love? Put them in an impossible situation and force them to make a choice.
Crime Fiction’s Favorite Dilemma: Love vs. Justice
Does your detective choose loyalty to a loved one over their duty to the law? Does a criminal commit one final act of violence to protect the person they love? These high-stakes choices reveal character depth and keep audiences hooked.
📖 Examples in Action:
Gone Girl – Nick Dunne must decide whether to remain trapped in a toxic, dangerous marriage or expose the truth about his wife’s crimes. Familial love.
L.A. Confidential – Officer Bud White is willing to risk his entire career and moral standing for the woman he loves. Eros love.
Broadchurch – Ellie Miller’s love for her family is tested when she must face the shocking truth about her husband’s involvement in a murder. Familial love.
Writing Tip: Put your characters in no-win scenarios where love is tested. Force them to make the hard call.
Give Villains Love-Driven Motives to Make Them More Complex
Some of the most chilling criminals in fiction aren’t motivated by money or power—but by love twisted into something dangerous. A great villain believes they are the hero of their own story, and oftentimes, love is the justification for their crimes.
Villains Motivated by Love:
Breaking Bad – Walter White’s descent into crime is fueled by his desire to financially provide for his family after his death—but that love warps into power-hungry destruction. Familial love.
The Girl with the Dragon Tattoo – Lisbeth Salander’s pursuit of revenge stems from a deep-seated need to protect herself and others from familial abuse after years of trauma. Familial love.
In the TV series, The Americans, our protagonist spies, Elizabeth and Philip Jennings (US names) and also our villains, depending on which country you’re rooting for: USA or Russia. Their entire life and mission in the United States is rooted in their love for motherland Russia. Agape love. It’s also rooted in their love for each other. Over the course of the series, their marriage goes from a function of the mission to one of eros love. They end the series stronger in both loves.
Writing Tip: Instead of making villains evil for the sake of it, tie their motivations to love, obsession, or loss—and watch how much richer and complex your story becomes.
Bonus: Other Ways to Use Love to Strengthen Your Crime Story
✔ Make love a red herring – Let readers believe a relationship is one thing when it’s really another. Is the doting husband secretly manipulating his wife? Is the caring best friend actually the mastermind behind the crime?
✔ Use love to create allies and enemies – A cop might bend the rules to protect someone they love. A suspect might confess just to shield a family member from suspicion.
✔ Always root your protagonist’s motive in her truest form of love – What type of love does she value above all overs? Love divine? Love of family? What love at her core?
At its core, love is what makes crime stories compelling. It’s what makes us care about the victims, root for the detectives, and sometimes even empathize with the criminals.
Whether it’s romantic, familial, platonic, or divine, love is the reason we keep turning the pages and watching the next episode.
