My Thoughts:

FBI Agent Gardner Camden is part of the Patterns and Recognition unit, PAR that tackles challenging cold cases, finding clues others have missed. Each quirky member is gifted in their specialty: a mathematician, a firearms expert, and a computer analyst.

 

Gardner’s team is called out when DNA of a murder victim matches a serial killer thought to be dead. Soon there’s another murder that seems to be connected and the team is tasked with finding the killer. It quickly becomes apparent this killer knows of the PAR unit and is leaving them clues. With the mistaken identity of the first murder, the FBI wants the case solved quickly and quietly and they want PAR to do it. They hop from scene to scene, as more is revealed, an undercurrent of urgency threaded through the narrative, keeping me on the edge of my seat!

 

Gardner is an interesting and likeable hero; one I rooted for!  His eidetic memory and knack for connecting random details/patterns make him excellent in solving cases, but the ins-and-outs of social interactions seem to escape him. Gardner’s backstory and how he ended up on the team is revealed, but the other’s backstories are only lightly touched on. Callie, a mathematician, Shooter, a firearms expert, Frank their supervisor, and the newbie, Richie. I look forward to getting to know more about them and seeing them settle in together as a team.

 

Head Cases was a thrilling mystery that had me hooked from the start! I can’t wait for the next one!

I alternately read and listened to Head Cases and can recommend either version. Will Damron is a new-to-me narrator, and he performed Gardner with a kind of matter-a-fact tone, something that fit with his character’s personality perfectly! I enjoyed his performance of all voices and I hope he continues to narrate the series!

4.5 Stars

Book Description:

Head Cases follows an enigmatic group of FBI agents as they hunt down a murderer seeking his own justice in this electrifying—and commercial—series debut.

FBI Agent Gardner Camden is an analytical genius with an affinity for puzzles. He also has a blind spot on the human side of investigations, a blindness that sometimes even includes people in his own life, like his beloved seven-year-old daughter Camila. Gardner and his squad of brilliant yet quirky agents make up the Patterns and Recognition (PAR) unit, the FBI’s hidden edge, brought in for cases that no one else can solve.

When DNA links a murder victim to a serial killer long presumed dead, the team springs into action. A second victim establishes a pattern, and the murderer begins leaving a trail of clues and riddles especially for Gardner. And while the PAR team is usually relegated to working cold cases from behind a desk, the investigation puts them on the road and into the public eye, following in the footsteps of a killer.

Along with Gardner, PAR consists of a mathematician, a weapons expert, a computer analyst, and their leader, a career agent. Each of them must use every skill they have to solve the riddle of the killer’s identity. But with the perpetrator somehow learning more and more about the team at PAR, can they protect themselves and their families…before it’s too late?

With an enigmatic case that will keep readers on the edge of their seats and a thoroughly engaging ensemble cast, John McMahon’s Head Cases is a triumph.
