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.
Thank you to St. Martin’s Press | Minotaur Books and John McMahon for a complimentary digital ARC of this novel via NetGalley. As always, I encourage you to read and form your own opinion.
Inside Man is out now! You can grab your copy here. You can also grab your copy of the first book in the PAR series, Head Cases, which you should absolutely read before Inside Man. You’ll thank me later.
