Boost your story's immunity to reader scrutiny with these fortifying nutrients. Learn the 5 C's of writing a great thriller novel from James Scott Bell.

Remember when Tommy Lee Jones holds up the empty shackles in The Fugitive and says, "You know, we're always fascinated when we find leg irons with no legs in 'em"? It makes me think of readers who pick up thrillers and find no thrills in them. Or at least not as many as there could be.

I'm not just talking about plot here. It's possible to have guns and bombs and hit men and terrorists and black helicopters and still not have a novel that grips the reader in the gut.

(10 ways to hook your reader and reel them in for good.)

For a healthy, fully functioning thriller, try some literary vitamin C. Dose your book with these five Cs and it will stand strong, chest out, ready to give your reader a run for the money.

1. Complex Characterizations

The first place to fortify a thriller is its cast of characters. A critical mistake made here can undermine even the best story concept.

Is your protagonist all good? That’s boring. Instead, the thriller hero needs to struggle with issues inside as well as outside. She's got to be a carrier of flaws as well as virtues. These roiling conflicts make her survival an open question.

When we first meet Detective Carol Starkey in Robert Crais' Demolition Angel, she's flicking her cigarette ash on the floor of a therapist's office, "pissed off" because it's been three years and her demons are still alive and well. Quite an introduction, especially for someone on the LAPD bomb detail. We know she has a short fuse. And we want to watch to see if it goes off.

(Robert Crais on passion, process, and plot twists.)

Brainstorm a list of at least 10 inner demons your hero has to fight. Ten. Get creative. Then choose the best one. Work that demon into your hero's backstory, and show how it is affecting him in the present—and could hinder him even further in the future. Give him actions that demonstrate the flaw.

Move on to the rest of your cast. Avoid the "stock character" trap, which can be especially perilous in this genre—e.g., the cold, buttoned-down FBI agent; the police detective with a drinking problem. Here's a good habit: Reject the first image you come up with when creating a character. Entertain several possibilities, always looking for a fresh take.

Then, give each character a point of potential conflict with your hero as well as with the other characters—especially those who are allies. Look for ways friends can become enemies or betrayers. Short of that, create more arguments.

To help you add complexity, make a character grid like this:

Now, fill in the blank boxes with possible relationships, secrets and areas of conflict. For example:

If possible connections are eluding you, try running this exercise for each of your main characters: The police come to the character's residence with a search warrant. In his closet is something he does not want anyone to find, ever.

What is it?

What does this reveal about the inner life of the character? Use the secrets and passions you discover to add another point of conflict within the cast.

Standout thrillers need complexity and webs of conflict, so that every page hums with tension.

2. Confrontation

I call the main action of a novel the confrontation. This is where the hero and antagonist battle over the high stakes a thriller demands.

When it comes to the antagonist, writers can easily make the opposite of the "all-good protagonist" mistake: They make their bad guy all bad. Worse, they make him all bad because he’s crazy.

More interesting confrontations come from a villain who is justified in what he does.

You mean, in doing evil things?

Yes, that's exactly what I mean—in his own mind, that is. How much more chilling is the bad guy who has a strong argument for his actions, or who even engenders a bit of sympathy? The crosscurrents of emotion this will create in your readers will deepen your thriller in ways that virtually no other technique can accomplish. The trick is not to overdo it—if you stack the deck against your villain, readers will feel manipulated.

Start by giving your antagonist just as rich a backstory as your hero. What hopes and dreams did he have? How were they dashed? What life-altering hurt did he suffer? Who betrayed him? How did all of this affect him over the course of his life?

Write out a closing argument for him. If he were in court, arguing to a jury about why he did the things he did in the novel, what would he say? Make it as persuasive as possible:

"Ladies and gentlemen of the jury, my name is Hannibal Lecter. You've heard a lot of lurid tales about me from the prosecutor. Now you will hear my side of the story. You will hear about a world that is better off without some people being in it. And you will hear about the conditions I endured inside the horror of a place called the Baltimore State Hospital for the Criminally Insane …"

It can feel a bit disturbing to try to understand someone you might hate in real life. Good. You are a writer. You go where angels fear to tread.

Now take all of that material and use it to strengthen the antagonist's position in the story. A stronger confrontation can only result.

3. Careening

There's nothing like a stunning twist or shock to keep readers flipping, clicking or swiping pages. Part of the fun for readers is thinking a story is going one way, and getting taken completely by surprise.

Harlan Coben is one of the reigning kings of the art of surprise. "I've rarely met a twist I didn't like," he has said. His method, if it can be called that, is to write himself "into a lot of corners" and see how things work out.

That's one way to go. Forcing your writer's mind to deal with conundrums is a great practice.

But there is another way. Pause after every scene and ask yourself: "What would a reader expect to happen next?" Create a list of at least three directions the story might take.

Then discard those three and do something different. I call this unanticipation.

Another method is the old Raymond Chandler advice: When things slow down, bring in a man with a gun. It doesn't have to be an actual man with an actual gun, of course. It can be anything that bursts into a scene and shakes things up. Here's the key: Get your imagination to give you the surprise without justification.

Make a quick list of at least 10 things that just pop into your mind. For example:

1. A woman runs in screaming.

2. The lights go out.

3. A car crashes through the wall.

4. Heart attack.

5. SWAT team outside.

6. Marching band outside.

7. TV announcer mentions character's name.

8. A baby cries (what baby?).

9. Blood drips down the wall.

10. Justin Bieber comes in with a gun.

Some things on your list will seem silly. That's OK. Don't judge. Look back and find the most original item, and only then find a reason for it. In this case, No. 8 creates the most interest for me. I have no idea where that came from or what it means. But I can make it mean something.

And so can you.

4. Coronary

The best thrillers stab the heart, throughout. They do it by getting readers to experience the emotions of the scenes.

How can you do that? First, by experiencing them yourself. Sense memory is a technique used by many serious actors. Here's how it works: You concentrate on recalling an emotional moment in your life, and recreate each of the senses in your memory (sight, smell, touch, sound, etc.) until you begin to feel the emotion again. And you will. The actor transfers that to her role; the writer, to the page.

When I was getting to the heart of one of my own thrillers-in-progress, a story of two brothers, I needed to feel what the younger one was experiencing when the bad guys came. I recalled a time when I was 6 or 7, and some bullies were holding me hostage on a hill. Terrified, I finally made a break for home and sobbed to my big brother about what had happened. He left me at the house.

I never saw those bullies in our neighborhood again.

When I wrote the scenes with the younger brother, I focused on feeling those moments again, and transferred those emotions to the page.

They're going to kill Chuck and they're going to do the same thing to me. That's why they have me tied up and they put another thing in my mouth and they won't let me talk. … They hit me. I'm in the back of some truck. They're taking me somewhere. I hope they take me where Chuck is. If they do anything to Chuck I will bite them. I will do anything I can to hurt them. Maybe I'm going to die but I will not die until I hurt them because of what they're going to do to Chuck.

Another way to tap into your character's heartbeat is the run-on sentence. Interview the character at the height of an emotion. Write down his reaction for at least 200 words without using a period. Then explore that text to find gems of emotional description. You might actually use some of it, as Horace McCoy did in his 1938 noir thriller, I Should Have Stayed Home:

All Dorothy's fault, I thought, cursing her in my mind with all the dirty words I could think of, all the filthy ones I could remember the kids in my old gang used to yell at white women as they passed through the neighborhood on their way to work in the whore houses, these are what you are, Dorothy, turning off Vine on to the boulevard, feeling awful and alone, even worse than that time my dog was killed by the Dixie Flyer, but telling myself in a very faint voice that even like this I was better off than the fellows I grew up with back in Georgia who were married and had kids and regular jobs and regular salaries and were doing the same old thing in the same old way and would go on doing it forever.

5. Communication

The original storytellers spun thrillers. When heroes went out into the dark world to confront monsters and demons and great beasts, the tribe vicariously lived the tale. But there was something more—they learned how to fight, act courageously and survive.

The first thrillers carried a message and helped bring a local community together.

Readers still seek that kind of story. So you ought to spend some time asking yourself what your thriller is really about. Does it offer hope for justice? Does it end with justice denied?

In short, what will the reader take away from your book?

Many aspiring thriller writers, perhaps seeing the genre as action-driven, avoid thinking about theme (or meaning, or premise). They prefer to let the characters duke it out, and leave it at that. There's nothing wrong with this approach, as long as you realize that you will be saying something. Why not be intentional about it?

Here's an exercise I call "The Dickens" (named for Charles and his time-traveling story A Christmas Carol): Go forward in time 20 years after your story ends. Your lead character is now 20 years older and has had time to reflect on all that happened in the story you told. You're now a reporter, and you track down the character and ask, "Looking back at everything that happened to you, why do you think you had to go through that? What life lesson did you learn that you can pass on to the rest of us?"

Let the character answer in a free-form way, for as long as possible, until you sense that it's right.

Now use all your skills to demonstrate that lesson at the end of the story itself, without necessarily using words. Give us Clarice Starling sleeping at last, the lambs of her nightmares silenced. Or Harry Bosch in Lost Light, holding for the first time the hands of the daughter he never knew he had.

Those are the moments that will take your thriller from entertaining to unforgettable.

Here's to the health of your thrillers.

*****

Writing strong first pages requires a great hook, a strong voice, and a clear premise. The first sentence should immediately catch the reader's attention, while the subsequent text should leave the reader wanting to dive further into the pages of the manuscript. But making the first pages of your story absolutely un-putdownable takes practice, patience, revision, and an eye for detail. Which is why we're here: to discuss what to do (and not to do) to make your opening pages stand out.
