Inside Man was one of my most anticipated reads of 2026, and it absolutely delivered! I love a good police procedural, but sometimes it’s hard to find one that genuinely feels fresh. John McMahon accomplishes that by pairing a complex, layered mystery with a uniquely constructed investigative team.

FBI agent Gardner Camden leads the Bureau’s secretive Patterns and Recognition (PAR) unit, a group of brilliant but unconventional agents brought together after career-defining moments (and not always in the way you think…) in other departments. Camden, an analytical genius who sees the world in patterns, thrives in high-level problem solving but struggles with the politics that often accompany leadership.

In this installment, the PAR team is tasked with two seemingly unrelated investigations. One involves a militia group stockpiling weapons and a murdered confidential informant. The other centers on a series of murdered women buried in north Florida. When evidence links both cases to the same unidentified man caught on camera, the scope of the investigation expands into something far more dangerous.

McMahon’s pacing is one of the novel’s greatest strengths. The story moves quickly, yet the layered plotting never becomes confusing. Each twist feels intentional, and the connections unfold in a way that rewards careful reading without overwhelming the audience.

Watching Camden’s analytical mind work through the evidence remains one of the most compelling elements of the series. His growth in this book adds additional depth. With the departure of the team’s former leader, he is forced to step fully into a leadership role while navigating internal FBI pressures. Leadership and diplomacy are not natural strengths for him, and that tension adds a realistic complexity to his character. The emotional weight of his mother’s coma further humanizes him and raises the personal stakes.

The PAR team continues to evolve as well. Their dynamic feels sharper and more cohesive, and the subtle development of Camden’s relationship with Cassie adds a welcome emotional thread without distracting from the central mystery.

Fast-paced, intelligent, and tightly constructed, Inside Man is a strong continuation of the series. Readers who enjoy puzzle-driven crime fiction and character-focused procedurals will find much to appreciate here. I’m already looking forward to the next installment.

Head Cases took me completely by surprise—and I loved every page of it.

This is an intelligent, character-driven police procedural that stands out in the crowded world of FBI thrillers. At its core is Agent Gardner Camden, a brilliant puzzle-solver with sharp instincts, emotional blind spots, and a quietly devastating personal history. He’s not your typical G-Man—and that’s exactly what makes him such a compelling lead.

Gardner heads up the Patterns and Recognition (PAR) Unit, a fringe FBI task force in Jacksonville made up of brilliant misfits who were all sent there for making mistakes or stepping out of line. The team is unconventional, awkward, and endlessly compelling. They don’t play by Bureau rules, but they solve the cases no one else can.

When DNA from a new murder victim links back to a long-dead serial killer, the team is thrust into an active case—rare for them. As more bodies drop, it becomes clear that the killer is leaving behind riddles specifically designed for Gardner. And this time, the case isn’t just professional—it’s personal. The killer knows things they shouldn’t, and the PAR team must stay one step ahead before the trail turns toward them and their families.

What sets Head Cases apart is its deeply flawed, emotionally rich cast. Each member of the PAR Unit is working through some form of damage—professional, personal, or both—and yet their quirks and failings are also what make them exceptional at their jobs.

Gardner is socially awkward, possibly neurodivergent, and entirely devoted to solving puzzles and doing what’s right—even when it’s cost him everything: his marriage, custody of his daughter Camila, and his career trajectory. Still, he wouldn’t change a thing. Cassie, his new partner, transferred to Jacksonville under murky circumstances and shares Gardner’s analytical mind and eye for detail. Their dynamic is layered and full of potential. And hopefully some smoochin’ in the later books. Shooter (yes, that’s what they call her) is the wildcard—an eccentric, badass weapons expert who might just steal the show. Frank, the team’s leader, brings quiet authority and calm—but he also seems to be keeping secrets. Richie, the new recruit, is sharp and capable… but the fact that his personnel file is sealed adds an intriguing mystery to the mix.

The plot moves at a gripping pace, with just enough twists to keep you guessing. The riddles and killer’s pattern are cleverly constructed without feeling gimmicky, and the final reveal genuinely surprised me. It’s amazing to be able to watch Gardner’s brain unravel the clues.

But what I loved most was how authentically human this story feels. Gardner’s neurodivergence isn’t romanticized or exaggerated, it’s simply part of him, and it shapes the way he processes the world, leads the team, and tries (imperfectly) to connect with his daughter. The emotional undercurrent between him and Camila is quiet, but it’s the heart of the book.

This is the kind of series opener that makes you want to binge-read sequels that haven’t even been written yet. If you’re a fan of Criminal Minds, Profiler, or simply love watching a team of outsiders crack impossible cases, this book is for you.

Sign me up for every future PAR Unit release. I’m hooked.
