What is A Thriller?

In this post, we explore the defining characteristics of a thriller, particularly psychological thrillers. From creating suspense and high stakes to delving into mind games and unreliable narrators, this genre keeps readers on the edge of their seats.


After I took the plunge and quit my job as a pathologist to write full time, the first novel I ever completed for adults was a psychological thriller. It is a genre near and dear to my heart. I love reading them, and love writing them even more. What is a psychological thriller? And what makes them so compelling? 

Let’s dig in.

Thriller is a genre of literature defined by the primary mood of dread and suspense. They aim to make readers unsettled, nervous, and eager to read what happens next. All fiction should elicit some amount of stress in the reader in the form of tension and conflict, but in a thriller novel, the stress is the main feature. They often feel cinematic and involve high stakes and dramatic plot points. 

In short, if it “thrills,” it is a thriller. 

In the introduction to Thriller, a major anthology published in June 2006, James Patterson says:

Thrillers provide such a rich literary feast. There are all kinds. The legal thriller, political, spy, action-adventure, medical, military, police, romantic, historical, religious, high-tech. The list goes on and on, with new variations constantly being invented. In fact, this openness to expansion is one of the genre's most enduring characteristics. But what gives the variety of thrillers a common ground is the intensity of emotions they create, particularly those of apprehension and exhilaration, of excitement and breathlessness, all designed to generate that all-important thrill. 

In other words, if a thriller doesn't thrill, it's not doing its job.

Thriller is a hybrid of mystery and horror, sharing a literary lineage with the epic and myth. Monsters, terror, and peril prevail. They are dark suspenseful plot-driven stories. 

In his excellent 2019 article for Writer’s Digest entitled, “The Differences Between a Crime, Mystery, and Thriller Novel” David Corbett again emphasizes the emotion: Of the three major suspense genres, thrillers are typically the most emotional, focusing on the fear, doubt, and dread of the hero as she faces some form of what Dean Koontz has deemed “terrible trouble.” 

There are many elements to thrillers that overlap with other novels of mystery and suspense but typically with an exaggerated atmosphere of menace and sudden violence, such as crime and often murder. A devastating crime is about to be committed or has been committed with the threat of another one looming. The villain is known, but his guilt is not certain—or the hero cannot accept the truth of his guilt. Uncertainty and doubt enhance the suspense.

The tension usually arises when the main character(s) is placed in a dangerous situation, and we spend the rest of the novel waiting to see if they’ll escape. Themes typically emphasize the dangerous world we live in, the vulnerability of the average person, and the inherent threat of the unknown. 

Thrillers can take place in exotic settings—think geopolitical and many spy thrillers—but most take place in ordinary suburbs and cities. The main character, the hero, is usually tough and resourceful, but essentially an ordinary person who is pitted against a villain determined to destroy them, their country, or the stability of society. 

Suspense is how an author builds tension throughout the story. It’s necessary in any genre, but it’s absolutely vital in thrillers. Ultimately, your goal for the reader is that they never want to put the book down. Each chapter ends with a cliffhanger, urgent question, or significant plot twist. And the plot must have high stakes. The characters must have a lot on the line—it needs to really matter they succeed. 

In a thriller, the plot should be driven by one big, important question. Think Chris Whitaker’s All the Colors from the Dark. The story begins when Patch is abducted when he is a young boy and held captive in a darkened room along with another young girl, Grace. Patch eventually escapes but spends the rest of his life searching for Grace. It is a complex, multilayered mystery involving missing persons, child kidnapping, and a serial killer weaving several plots lines, each with their own twist, but it is Patch’s quest that becomes the central question that drives much of the suspense throughout the novel. Who was Grace and what happened to her? 

While action does not need to be non-stop, suspense and intrigue need to be constant. There must be a sense of urgency to keep you turning the page.

This basic story structure emphasizes the importance of reader expectations: There is a distinct hero and a villain. The attack on the hero is relentless with escalating terror and dread. The hero must be vulnerable—not just physically but psychologically. 

So, what is a psychological thriller and what makes them different from other types of thrillers? 

The biggest questions revolve around the minds and behavior of the main characters. Common elements in include plot twistspsychologyobsession, and mind games. They incorporate elements of mystery and include themes of crime, morality, mental illness, substance abuse, multiple realities, and unreliable narrators. 

psychological thriller finds the terror in madness and paranoia. Here the threat is diabolical but more contained, even intimate—usually targeting the protagonist and/or his family—and the hero is often relatively ordinary. 

It is the upending of our prosaic circumstances that disconcert us the most. This is why many psychological thrillers are domestic dramas set in the home, threatening our most cherished relationships such as husband and wife, mother and daughter, or sister and sister. The protagonist (and the reader) come to think if we are not safe in our own home, we must not be safe anywhere.  

Psychological thrillers generally, but not always, stay away from elements of fantasy or science fiction, focusing on events that could take place in real life. However, with advances in medical science and robotics, and the rise of AI, this is changing. Near-future psychological thrillers involving clones or robots gone awry can be eerily convincing. 

In summary, like all good stories, it comes down to setting and character with a problem. The reader must care about what happens next. Psychological thrillers are highly emotional and revolve around the minds and behavior of the main characters. Common elements in include plot twists, mind games, and unreliable narrators to create an atmosphere of menace with looming threats. They are suspenseful and filled with fear and dread to keep readers turning the page. 

In the next series of essays, I will discuss five specific elements we see in a psychological thriller.

What if?: A Most Important Question 

Every author is asked where they get their ideas. This post explores how an idea transforms into a full story, starting with the crucial question: What if? It’s the foundation of every gripping narrative.

By DP Lyle 


Every author has been asked: Where do you get your ideas? The short answer is: Everywhere. Something you see or read germinates an idea, and a story unfolds. Sometimes the story comes together quickly, but most often weeks of building mental scenes and snippets of dialog, setting, and action must be waded through before pen meets paper. 

An overheard conversation might be the spark. Or a couple talking/arguing/laughing at a nearby restaurant table. Maybe an odd character strolling down the street. Perhaps an idea simply pops into your head from wherever those thoughts arise. 

Okay, so you have an idea. Now what? An idea isn’t a story. Ideas are a dime a dozen. They are literally everywhere. The key is to find an idea that can stand up through a 100,000-word manuscript. No small trick.

To do this, the original idea must be refined and fleshed out. An idea can become a scene, but to be a full-length novel it must evolve and expand. It must become a premise, or what many call “The Central Story Question.” It’s what the story is really about.

To become a premise, the original idea must ultimately lead to the question: What if? 

What if this happened? What if that person did this? What if that dude in the shabby clothes was actually a rogue undercover agent with a deadly agenda? What if the restaurant couple was planning a murder? What if that briefcase contained state secrets? Or an explosive device? Or a deadly virus?

From those two words--What if?--stories arise.

The power of your story’s What If? can’t be overestimated. If it is done correctly and not lost in the writing. A good What if? states the main character, the situation, the stakes, and, most importantly, the Central Story Question. 

It is the answering of this question that is the story.

Okay, so our restaurant couple is planning a murder. Who, what, when, where, and, most importantly, why? It’s always the why that makes a great story. Is it to get out of a messy marriage and save all that alimony money, or to cash in that million-dollar insurance policy, or to cover an embezzlement from a company they work for, or to seek revenge for some act? Even though the original idea was a couple planning a murder, each of these scenarios generates a different story. Each will lead your sleuth, who must solve the murder, into a different world.

What if a young couple witnesses a murder and in so doing put themselves in the cross hairs of a transnational criminal organization?

This is the What If? for my latest Cain/Harper thriller, TUNICA. 

The What If? should be stated in about 25 words or less. Because the What If? is brief, it’s often called the elevator pitch or the agent pitch. It communicates your story in the most efficient terms. We’ve all heard writers respond when asked what their story is about by saying things like, “Well, there’s this guy who lives on an island. And he hates the water. And a big shark is killing people and this is threatening to shut down the town’s beaches on a holiday weekend. And then there’s this other guy who is a shark expert and he has a really cool boat. Oh, I forgot, the first guy is the chief of police.” Yawn.

What if a hydrophobic, island-community police chief must go out on the water to kill a predatory shark to save the town’s summer economy and to prove his own self-worth?

What if an FBI trainee must exchange personal information with a sadistic serial killer in order to track another serial killer and save a Senator’s daughter?

What if the youngest son of a mafia family takes revenge on the men who shot his father and becomes the new godfather, losing his own soul in the process?

These are of course Jaws, Silence of the Lambs, and The Godfather, respectively. See how these What If?s reveal the protagonist and cleanly state the story premise? Read these books or watch the movies and you will see that each scene moves toward answering the story’s What If? Each of your scenes should, too. If not, consider cutting, or at least reworking, those that don’t.

Many authors consume weeks creating the What If? for their story. Constantly refining it, making it more on point. You should, too. It’s that important. It concisely states the Central Story Question.

Here’s a tip: When your What If? is completed to your satisfaction, print it out and tape it to your computer or the front of your writing pad so you will see it every time you sit down to write. Before writing each scene, read your What If? and ask yourself, “Does this scene help answer the Central Story Question?” If you do this, you will never lose sight of what your story is about. Particularly in the dreaded middle, where so many stories get lost in the jumble of character and backstory and cool dialog all the other stuff that goes into a manuscript. The What If? keeps you focused and on track.

Never Make Your Critique Partner Cry!

Giving feedback is an art, especially in critique partnerships. Learn how to offer constructive criticism that encourages, not discourages, while keeping your critique partner’s feelings in mind. It’s all about balance, communication, and a shared commitment to growth.


We writers are not the best judges of our own work. Neither are most of our family and friends. They’ll either love everything we write because they don’t know any better, or they don’t want to hurt our feelings. Conversely, some will sic the green-eyed monster on us, telling us not to quit our day job. 

That’s why critique groups and/or partners are an invaluable tool in every author’s toolkit. They’re the writer friends we rely on when we’ve developed writer’s block or written ourselves into a corner. They brainstorm with us when the ideas don’t come, and they offer us honest criticism chapter after chapter, helping us hone our work until it’s ready for submission. Then, they either commiserate with us when the rejection letters arrive or whoop it up when we get that offer of representation or a book contract.

And because this is a partnership, we do the same for them.

However, none of us wants to hear that the 400-page baby we birthed through our fingertips onto the printed page is butt ugly. And neither do our critique partners. Just as we hope to find critiquers who will offer us constructive criticism, we also need to be able to give constructive criticism to others in return. The key is always to encourage, never discourage. Luckily, there are ways to do this.

Always remember to point out positives as well as negatives. It’s just as important for a writer to know what she’s doing well and correctly as what she’s doing poorly and incorrectly. As you read a work-in-progress, point out those parts you especially like, but don’t be afraid to point out areas that need work. Most importantly, in both cases, don’t forget to explain why. 

Our critique partners often become good friends, and it’s hard to criticize friends for fear of hurting their feelings. But if we can’t be objective and honest with our critiques, we’re not helping each other. We all need to know where our manuscripts are not working as well as where they are working.

It’s important to find a group or partner who either writes in the same genre or has a good deal of knowledge about each other’s genre. However, interests change. Writers often decide to explore different genres. What happens if Helen Historical is suddenly bitten by the vampire bug? You curl your nose up. You shudder. Vampires give you the creeps. You want to be a good critique partner, but try as you might, you can’t read those chapters with an open mind. If that’s the case, it’s time to step aside—at least until Helen returns to her historicals or you fall in love with bloodsuckers. 

Some writers have a hang-up about red ink. They feel like someone has taken a knife to their manuscript and slashed it to death. Bold type in all caps will make some writers feel as though they’re being yelled at. Be sensitive to how your partners feel about how you deliver comments. Avoid red type and all caps when making notes on digital pages. When working from printed pages, avoid red ink and thick black sharpies. Never write comments in script. Print them. We can all read our own handwriting, but others may struggle to decipher our scrawls.

If you’re one of those writers with a great handle on punctuation or grammar, your partners might ask you to do line edits. Rather than correcting their work, point out problem areas. This way, the writer will learn from the experience and not make the same mistake in future works. 

Keep in mind that just because you would write a scene or a character differently, it doesn’t make the author’s way wrong. If your partner is having problems with a sentence or scene and asks for assistance, offer suggestions, but never rewrite her manuscript in your style.

Often, writers gravitate toward other writers of the same experience level. This usually makes for a group or partnership that can work together more comfortably. If the various members are at different levels in their writing journeys, the more novice writers may begin to depend too much on the more advanced writers, and the more advanced writers may begin to feel that they aren’t getting much out of the group. Since we all progress at a different pace, you may discover over time that you’ve outgrown your present group and need to move on to another.

Manuscripts should be free of typos and spelling errors, but we all occasionally suffer from a short circuit between our brains, fingers, and eyes. No matter how many times we read and reread something, we often miss a “there” for a “their” or a “that” for a “than.” If your partner is getting ready to send her work out to an editor or agent, offer to read through her work with an eye toward the technical, but keep in mind that punctuation and sentence structure is often a matter of style. Point out grammatical errors such as misplaced modifiers and subject-verb disagreements, but keep in mind that characters often dictate grammar. A street urchin in Victorian England won’t speak like the Earl of Sussex.

Pay attention to structure as you read a work-in-progress. Every scene should have a purpose. Make sure the pacing is appropriate for the scene/event taking place. In the middle of a chase scene, the heroine shouldn’t be noticing the intricately detailed pattern of the hero’s tie. 

Sentences should be clear and understandable. Point out if the writer has gone off on a tangent about something superfluous to the scene, such as extraneous background information or too much detail. By the same token, note if the author doesn’t supply enough details and description for the characters and settings to come alive. 

Highlight non-descript words such as “it” or “thing” or bland words such as “pretty” or “nice.” Suggest substituting more specific or descriptive words. If the author uses clichés, suggest she find another phrase. Clichés bore readers. Also note repetitive word usage and sentence structure. 

Understand basic rules of writing before you offer to critique someone else. For many writers, passive voice is a difficult concept to grasp. Not every sentence using the various forms of the verb “to be” is passive. Passive voice is when the subject is acted upon. Active voice is when the subject is acting. 

Point of view is another difficult concept. Make certain you understand it before you criticize others for misusing it. Check for bouncing points of view within a scene, but keep in mind, point of view can change from scene to scene. However, if you feel like you’re at a ping-pong match, make the author aware of that.

Finally, know your facts before criticizing someone else. If you suspect the writer’s information is inaccurate, ask if she’s done any research on the subject. If she tells you she saw a similar event on a television show or in a movie, suggest she check the library or ask an expert. The media is notorious for taking liberties with facts and events.
