Head Cases follows an enigmatic group of FBI agents as they hunt down a murderer seeking his own justice in this electrifyingand commercialseries 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 FBIs 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 killers identity. But with the perpetrator somehow learning more and more about the team at PAR, can they protect themselves and their familiesbefore its too late
With an enigmatic case that will keep readers on the edge of their seats and a thoroughly engaging ensemble cast, John McMahons Head Cases is a triumph.
Mr. McMahons inventive, eventful, smartly written Head Cases, with its brilliant but fallible protagonist, its twisted-minded perpetrator, and its mix of sentiment and intrigue, is a terrific debut that augurs well for further installments in the series. The Wall Street Journal
"A stellar new series...Head Cases balances fully fleshed-out, quirky characters with McMahon's fine eye for details about the inner workings of investigations coupled with methodical plotting...McMahon's precise storytelling in Head Cases should assure many adventures with this intelligent team."Oline Cogdill, South Florida Sun Sentinel
In this suspenseful cat and mouse thriller, Camden balances brilliance with a deeply flawed awareness of social cues, retaining the edge of a compelling protagonist. This, combined with McMahon's gripping plot, will pull readers in.Booklist
McMahon introduces several clever wrinkles to this classic cat-and-mouse setup, while making the socially awkward Camden and his colleagues three-dimensional enough to sustain future installments. With pulse-pounding action and enough surprises to blindside even seasoned mystery fans, this is an excellent start. Publishers Weekly (Starred review)
