Your novels combine relentless action with emotionally complex characters. How do you strike the balance between pulse-pounding suspense and genuine human drama?
In my books, there is no plot without compelling characters to drive it. My narrative style is to be invisible to the reader, with every action, thought and development filtered through a point-of-view character. If someone is kidnapped, we feel the fear and the anger and the frustration. No punch is thrown or no impact is landed without it being felt by a character on the page. I write that way deliberately to keep the reader close to the action of the story and thoroughly engaged with characters—people—about whom they’ve come to care a great deal.
Nathan’s Run remains one of the defining thrillers of your career. Looking back, what do you think made that novel resonate so strongly with readers?
We first meet 12-year-old Nathan Bailey as a terrified boy on the run. He’s barefoot and his orange juvenile detention center jumpsuit is wet with the blood of the drunken guard he was forced to kill in self-defense before he used the guard’s keys to escape confinement. The police see him as a cop killer on the run, and an ambitious prosecutor sees the boy as his highway to become a US senator. No one suspects the truth, that the guard who tried to kill him was paid to do so by powerful people who remain dedicated to taking the boy’s life. Orphaned and alone, Nathan feels helpless and hopeless. When he hears a radio shock jock who calls herself The Bitch on her nationally syndicated radio show suggests that 12-year-olds who commit adult crimes should be treated as adults in the system, Nathan calls into the show to tell his side of the story. The truth is brutal and the honesty of the boy’s delivery changes the media narrative, even as ambitious politicians and a contract killer remain committed to either ruining or ending Nathan’s life.
I know from letters and emails that Nathan’s Run brought many readers to tears and made them hug their kids a little tighter. Without an advocate in the system, a child has little voice, and what voice he has is often ignored. Nathan’s Run exposes the importance of the media in people’s minds as to who the good guys and bad guys are.
Jonathan Grave has become one of the most enduring heroes in modern thriller fiction. How has he evolved since No Mercy, and has he ever surprised you as a writer?
Jonathan Grave is a freelance hostage rescue specialist. A former Delta Force operator, he and his team are dedicated to reuniting families, but he is not a cop. He doesn’t wait for warrants before listening in on telephone conversations or kicking in the door of the kidnappers and shooting them dead. In the eyes of the law, that makes him a murderer, while in the eyes of the reunited family, he is a hero.
Jonathan lives by a code that sometimes requires the parsing of ethical and moral standards. He’s not motivated by revenge or money, but rather by the injustice that perpetrators would so violate innocents’ lives as to commit terrorist acts against them. The legal system moves slowly in order to protect the rights of the bad guys. Jonathan sees every extra moment of misery experienced by a hostage as an intolerable delay of justice. This puts him on the side of the angels, even though it puts him on the wrong side of the law.
The biggest challenge for Jonathan and his team is to avoid stepping over the line from rescuer to punisher. On rare occasions, he can’t help himself. And on those occasions, he surprises both of us.
Your background in explosives safety and emergency services gives your stories an extraordinary sense of realism. How much of your professional experience finds its way into your fiction?
Reality is important to me, and in my fiction, the laws of chemistry and physics always apply, as do the limitations of human anatomy. I know from my experience as an EMT that a bullet wound to the shoulder is not something to be shrugged off, but rather is devastating, at least in the short term. Jonathan and his team are all skilled as combat medics, and those skills come directly from my own training.
During my years in the fire and rescue service, I’ve delivered babies, and I’ve held children as they died. That changes you as a person, and that kind of experience directly or indirectly influences everything I write. As a very young man—starting in my early 20s—it was my job to walk into the worst moment in people’s lives and bring order to chaos. When I left, more times than not, those people’s worlds were at least a little better than when I arrived.
Six Minutes to Freedom tells an incredible true story. How did writing non-fiction differ from creating your fictional thrillers, and what did you learn from that experience?
Six Minutes to Freedom tells a story of extraordinary heroism, in which a band of Panamanian Rotarians came very close to running the murderous Manuel Noriega out of power. Unfortunately, the effort failed, leading to the arrest of Kurt Muse, an American ex-pat who led the conspiracy.
Kurt’s rescue became the focus of the US Army’s elite Special Forces Operational Detachment-Delta, commonly known as Delta Force. That rescue operation, code named Operation Acid Gambit, became the stuff of legend within the Spec Ops community. It took a long time and a lot of meetings and phone calls for me to finally gain permission for those operators to tell their story, and the result is a book that gives me great pride to have been a part of.
Even more, the process of writing that book gave me access to the world of special operations that would otherwise have remained invisible to me. That access, and the trust and cooperation I have earned within that community, have allowed me to bring Jonathan Grave’s world to life on the page.
Your books often explore questions of justice, loyalty and personal responsibility. Are these themes something you consciously develop, or do they emerge naturally during the writing process?
To be honest, there’s not a lot about my writing or my books that are the result of conscious deliberation. The stories arrive in my head and I write them down. By happenstance, I suppose, those are exactly the themes of much of my writing.
The themes of justice and service and personal responsibility come from a quirk in my DNA. My great-grandfather, Ike Gilstrap, was a deputy US marshal in Indian Territory, the area now known as Oklahoma. He was killed in the line of duty in 1906 while hunting down the murderers of a fellow deputy marshal. His son, my grandfather, Clifford Gilstrap, was awarded multiple medals for valor in World War One, along with a Purple Heart after being shot in the elbow. My father, James Gilstrap, was a career Naval officer and a pioneer in helicopter aviation. He wrote The Principles of Helicopter Flight, which became the Navy’s early text for flight schools.
You’ve written novels, screenplays and collaborated on film adaptations. How has screenwriting influenced the way you structure your novels?
I see screenwriting as an entirely different art form than writing novels, and with very little crossover for me. While each is a medium for telling stories, screenwriting is fundamentally collaborative. The screenplay is just the beginning of a project that will ultimately involve many other people. A novel, on the other hand, is a solitary work of art, where the author plays every role, both in front of and behind the proverbial camera.
Readers have followed Jonathan Grave through many adventures. Do you already know where his journey will ultimately end, or is that something even you have yet to discover?
I don’t have an end in sight for Jonathan Grave. Even after 17 books, with at least one more in the pipeline, it’s hard to conceive of a storyline that I could not hang on the structure of Jonathan’s world.
The thriller genre has changed significantly over the past three decades. What developments have excited you most, and what do you think readers will be looking for in the years ahead?
I am excited that readers have so many ways available to them to access stories. Thirty years ago, the audio versions of my books were available only as a massive collection of cassette tapes, or alternatively, as an entirely unsatisfying 3- or 4-tape abridgement. Now, recorded books are available on everybody’s favorite streaming service. Ebook readers now allow bibliophiles to carry hundreds of volumes in their purse or briefcase.
While consolidation among legacy publishers has driven advances down across the board, the growth of new publishers and new publishing paradigms have provided more opportunities for authors to find their audience. In the shadow of this opportunity, unfortunately comes the explosion of self-published “books” pushed out way too soon by “authors” who don’t know what they’re doing. That flood of dreck vastly complicates the effort for talented indy authors to gain any traction.
As for the thriller genre itself, I’m not sure that much has changed. The bad guys have evolved away from the Soviet Union and organized crime to Islamic terrorists and drug cartels, but stories are stories, and when they’re well-told they will always resonate with readers.
What writing habits or techniques would you recommend to aspiring authors who want to create gripping, page-turning suspense novels?
Genre notwithstanding, there’s only one inviolable rule to writing a book. Are you ready? It’s for the author to plant their butt in a a chair and write the book—all the way from “Chapter One” to “The End.” In my experience, when writers have the discipline to finish an 80,000-word project, they’re well on the way to publishing success.
You’ve spent years researching dangerous situations—what’s the most ordinary everyday object that people should probably respect a little more?
This is easy. The kitchen mandoline. What could go wrong sweeping your hand across a stationary razor blade?
