The Thriller Writer Lab is where every thriller goes under the microscope, one book at a time. On this show, bestselling, award-winning, and emerging thriller authors share the craft, psychology, and real-world experience behind today's most gripping stories. We go inside the minds behind the twists, the characters, and the moments that keep readers turning the page. Each episode begins with a two-minute book pitch, then dives into the decisions that shaped it — the risks taken, the rewrites that didn't work, the dead ends, and the breakthroughs that made it stronger. If you write thrillers or want to know what's really behind the stories you can't put down, this is the conversation for you.

    She Rewrote Her Literary Debut From Scratch as a Thriller | Getting It Right with Karen E. Osborne

    Award winning author Karen E. Osborne’s debut novel, Getting It Right, came out in 2017 as literary fiction. Years later its two leads, Alex and Kara, started talking to her again, and once she began a sequel she realized she was changing so much that the first book had to be rewritten to match. There was also a timeline problem: left alone, the original would have made both women 40 in the sequel, and in her words, “they’re not mature enough to be 40 years old.” So she rewrote the book from scratch in about five months with the original beside her, keeping the same two women but giving them new experiences, new characters and scenes, a changed ending, and a murder, moving it into the thriller genre she writes in now. As a discovery writer, she talks about how the old book worked almost like an outline, and why a sequel means you can’t just make everything up again. She also breaks down writing a father the reader only sees through other characters’ eyes, building Kara as a trauma survivor who isn’t a villain, and the beta reader question that made her rethink an ending: what did you promise at the beginning? Key Takeaways: Why her characters’ ages meant the first book had to change before the sequel could work How she rewrote a published literary novel from scratch as a psychological thriller in about five months How a discovery writer uses an existing book like an outline, and what a sequel locks in place Why the father at the center of the story never gets his own point of view Why she wrote a trauma survivor as a whole, complex character instead of a villain Karen E.

    He Tried to Outsmart James Patterson, Then Patterson Converted Him to Outlining | The First Scarlet Door with J.D. Barker

    J.D. Barker spent his early career as a strict pantser, writing more than half a dozen novels without an outline, when a phone call from James Patterson turned into an unlikely writing partnership. Patterson is a hardcore outliner who writes thirty to fifty pages of outline before starting a book, so the two agreed to try it Barker's way first. They wrote The Coast to Coast Murders by pantsing it scene by scene, each one trying to trap the other in an impossible spot, sending new pages back and forth. The book ran to 170,000 words, with 50,000 to 60,000 cut before it worked. Afterward, Patterson turned the tables and handed Barker a full outline for their next book, The Noise, which came together fast with almost nothing left on the cutting room floor. Barker calls it a turning point for how he approaches most of his own books since, though for this new prequel trilogy specifically he used a hybrid method, tracking the original series' twists and dates on a notepad rather than building a full outline. He also talks about writing all three prequels in secret before showing them to his own agent, and how the trilogy is built to make longtime readers unlearn what they thought they knew. Key Takeaways: Why he agreed to write a whole novel by pantsing before ever trying an outline with James Patterson How writing The Coast to Coast Murders by trading chapters back and forth shaped its twists Why one outlined book, The Noise, converted him from a lifelong pantser into a hardcore outliner How he tracked a decade-old trilogy's twists and dates on a notepad to write this new prequel Why he wrote all three prequels in secret before showing them to his own agent J.D.

    Spoiler Episode | The Mentor with Angela Douglas

    This is the spoiler discussion for The Mentor with Angela Douglas. If you haven't read the book or heard the full conversation yet, stop here, this episode gives away the ending. Angela goes past the pitch: the other endings she wrote before landing on the one in the book, including a documentary-style version she cut for being too explanatory, and the red herrings she planted for Natalie and a handful of other suspects along the way. She also talks about a reader theory she never planted on purpose, listening back to the entire manuscript with text-to-speech to make sure the clues actually landed, cutting the book from around 93,000 words down to 80,000 in the edit, and why Karla, the character she made intentionally unlikable, ended up being the most fun one to write.

    She Wrote a Thriller About Every Writer's Worst Nightmare: A Stolen Story | The Mentor with Angela Douglas

    Angela Douglas asked herself a question before she'd published a single book: what's the worst thing that could happen to a writer? She landed on an answer while working through lockdown on her still-unpublished first novel: having one of your stories stolen. That became the premise for The Mentor, a psychological thriller about Karla, an author accused of basing her breakout book on a former student's real life. Angela likes writing characters readers won't warm to right away, and Karla is one of them. To keep her from reading as one-dimensional, Angela added details that never made the original outline, including a strained relationship with Karla's mother. The book also splits into two points of view, uses an outlining method she calls waypoint writing instead of a fixed chapter plan, and went through more than one ending before she landed on the one that made the final book. Key Takeaways Why she's drawn to writing unlikable characters, and how she made sure Karla still had a reason to be the way she is. Why she rewrote The Mentor's ending more than once before one version finally stuck. How outlining toward scene “waypoints” instead of a fixed chapter plan changed her process Why she split the story into two points of view instead of writing Karla's story alone. Why she kept the book's 2020 setting even knowing it would cost her some readers.

He also previews what's coming in the next two Garris Kelly books, walks through why the opening chapter is told from two characters' points of view instead of one, and talks about his wife's role as his first reader and the unpublished novel that came before Another Try.

    14 Years in War Crimes Courtrooms Before Writing His Spy Thriller | Another Try with Gene Koon

    Gene Koon spent 14 years as a UN video director with no plan to write a novel. His best material wasn't research he went looking for, it was testimony he sat through incidentally, sitting in on the Yugoslavian war crimes trials where intelligence operatives sometimes testified in closed session. The more he listened, the more he suspected these people could make compelling characters for a book, so he filed the idea away. Years later, that idea became the starting point for Another Try. From there, Gene built the book around a specific complication: what happens to an operative whose entire skill depends on staying hidden once the president publicly credits him for a cartel takedown and turns him into a reluctant celebrity. He talks through writing Garris's reaction discovery-style rather than plotting it out in advance, and why knowing the book's literal last two words within the first hour of writing shaped everything that came before them. Key Takeaways: How 14 years of real war crimes testimony gave him the idea for a cast of intelligence operatives Why he wrote his celebrity-spy character's reaction by discovery instead of planning it in advance How knowing his novel's last two words within the first hour shaped the entire draft Why every chapter needs its own hook, even for the writer His research philosophy: give readers just enough detail, then move on Gene Koon Another Try: https://www.amazon.com/Another-Try-Gene-Koon/dp/B0DQ52L6RL Follow Gene Koon online: https://genekoon.com/ Want to be part of the conversation?

    A Research Trip Ruined His Outline | The House That Held Her with Ellis Hart

    Ellis Hart didn't plan to write the tunnel scene in The House That Held Her, it didn't exist until a research trip to Mount Dora, Florida changed things. Down at the docks, he found a real system of rainwater runoff tunnels pouring into Lake Dora, and knew immediately he had to work it into the book. It became his favorite chapter, and it only exists because he went and looked in person. Mark and Ellis also get into his outlining process and character bibles, why his beta readers made him rewrite the book's ending, how a psychological thriller started pulling toward horror partway through, and why he put a content warning page inside the book itself.
