Sherlock Holmes. Jane Marple. Jack Reacher.
Three famous names with something important in common … aside from the fact that each of them solves crimes in mystery or thriller novels.
What is this common element?
Readers love them.
The key to writing successful mysteries and thrillers doesn’t lie in careful plotting, clever crimes, or sneaky suspects. The heart of these stories beats in the chest of the sleuth.
Everyone enjoys a puzzle, and a tightly-woven plot is important, but readers return to a mystery (or thriller) series because they want to spend more time with a favorite hero(ine). Solving the puzzle is much more fun when you “ride along” with a friend, and a well-written sleuth is a reader’s friend indeed.
So before you sit down to commit—and solve—the initial crime in your manuscript, hunt down a compelling hero (or heroine) your readers will remember long after they turn the final page.
How do you “find” such a person? Let’s look at a few of the characteristics that most successful sleuths (and thriller-heroes) have in common:
1. Unusual Occupations. Many authors assume a sleuth must be a professional. The mystery and thriller shelves are filled with FBI agents, police, and forensic specialists doing their best to catch the killer and save the world.
But with so many “standard” crime solvers already in circulation, sometimes readers like to see a different kind of sleuth.
Brother Cadfael is a monk. Miss Marple, a widow. My own detective, Hiro Hattori, is a ninja.
Giving your hero a lesser-known occupation opens new worlds for the reader and also allows you a different range of crime-solving skills. Be creative! Your readers will love the change.
2. A Limp, An Eyepatch, and Battle Scars. In his popular screenwriting how-to, SAVE THE CAT, Blake Snyder recommends giving every character “a limp and an eyepatch” to distinguish him (or her) from the other characters in the scene. The idea applies to novels, too, and a good detective always has an unusual physical characteristic (or “tell”).
The characteristic can either relate your sleuth’s physical appearance—Is he missing an eye or a finger? Does she dye her eyebrows green?—or you can use it to establish a mood or reaction. My detective, Hiro Hattori, has a tendency to raise an eyebrow for ironic effect. His sidekick, Father Mateo, runs a hand through his hair when distressed or upset.
In addition to adding uniqueness and depth of character, physical characteristics can become an effective shorthand for a character’s mood or thought.
3. And Also, a Trunk Full of Baggage. Special Agent Gibbs (of NCIS) lost his wife and daughter (they were murdered by a drug lord). Jack Reacher has a shadowed past, and lives like he’s on the run. Miss Marple never married, and she’s crotchety as the day is long.
Nobody’s perfect, and your sleuth should not be, either. Every person has experienced disappointment, injury, and unresolved issues (or broken dreams). Your hero needs to suffer, too.
Whether the suffering happens onstage (for example, the death of a family member) or off (a tragedy or problem in the past) is up to you. But you must do something. Readers respond to damaged heroes. Watching a character overcome her own problems to help someone else is compelling on many levels.
Take a hammer to your sleuth’s emotional kneecaps. Use your plot or series to help him recover.
Your readers will love you—and your detective—for it.
4. Keep the Skeletons IN the Closet (Mostly). A good detective or thriller hero must feel like a real person, which almost always involves an extensive and detailed backstory.
Readers hate backstory. Flights of memory, or fancy, interrupt the flow of the narrative and distract from the sleuth’s objective: solving the crime.
The answer? Treat your detective’s backstory like a good mystery: drop some clues, but don’t reveal the entire thing. Spread the story across the series. Hide it in the stories like an Easter bunny dropping chocolate eggs. (Don’t spend too long on that metaphor. You don’t want to think about where those “chocolates” come from…)
By keeping your hero’s skeletons IN the closet, except for occasional peeks, you’ll keep your readers engaged, intrigued, and eager for the next reveal.
5. It’s Dangerous to Go Alone ... Some sleuths do solve crimes alone, but most of them have a sidekick, a pet, or both. Sidekicks serve an important purpose (which, hopefully, I’ll get to share in more detail next month). Pets do too. They humanize the hero(ine) and draw the reader closer. Incorporating one, or both, allows the writer to bring the reader right into the story, alongside the sleuth, and to see the sleuth behaving like a human being as well as a hero.
The choices are limitless, and the options as wide as your imagination.
You don’t have to integrate all of these tips to create a fantastic, compelling sleuth. Select the ones that work for you, and ignore the ones that don’t. Even if you work with only one or two of these options, you’ll find your hero becoming increasingly three-dimensional and intriguing … characteristics that keep your readers coming back for more.
Have you ever thought about writing a mystery? How about a thriller? Do you use some or all of these elements when creating your protagonists? (They work in other genres too, you know!)
