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.

A Macmillan Audio production from Minotaur Books.

The New York Times called John McMahon’s debut novel, The Good Detective “pretty much perfect” and listed it among their “Top Ten Crime Novels of 2019.” The book was a finalist for the 2020 Edgar Award and the ITW Thriller Award, both for Best First Novel. Head Cases is his fourth novel. John currently lives in Southern California with his wife, two kids and a rescue dog. He splits his time between crime writing and his day job in advertising.

Reviews

Praise for Head Cases

“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)

"A must for your TBR pile."—FirstClue

"Head Cases begins as a riveting story about the hunt for an apex predator—a killer of serial killers—but quickly becomes so much more: the only road back to what’s left of one man's family, friendships, and identity. It’s a taut, thrilling read.” —Jess Lourey, Edgar-nominated author of The Taken Ones

"Grabbed me from page one!" – J.A. Jance

“John McMahon's Head Cases is everything this crime fiction-lover could want: gripping, twisty, and atmospheric, with a harrowing and intriguing plot, gorgeous prose, and fresh and compelling characters. McMahon doesn’t just knock the ball out of the park with this one—he sends it flying into the next universe. I sincerely hope this is the beginning of a new series because I want more!” – Karen Dionne, author of the #1 international bestseller The Marsh King's Daughter and The Wicked Sister

"I couldn’t get enough of this addictive, propulsive story of intellect and intrigue. Head Cases is a masterfully-done game of cat and mouse with an unforgettable cast of characters." —Matthew Quirk, New York Times bestselling author of The Night Agent
