Head Cases

by John McMahon and John McMahon

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.

Customer Reviews

The PAR Unit is great!

Camden Gardner is a fascinating character in the way he thinks and solves twisty cases. He and the other members of the PAR Unit may be outcasts but they sure get the job done one way or another. As this is a first book and intro into this special group, it does a great job in introducing the important characters, fleshing them out as they are thrown into this case of a serial killer offing other serial killers (including one that everyone thought had died in a fire). I like that the members of the group (Cassie, Frank, Shooter and newbie Rich) are very distinct with their own strengths and weakness (no cookie cutter characters here!). It made for a very exciting read as Camden and the others race to solve the case before more people die. Nicely twisty and thrilling! This is the first book I have read by this author but you can be sure I will try his other ones, as well as wait eagerly for more books with Camden and the PAR Unit! Thank you to NetGalley and the publisher for the chance to read and review this book!
