Head Cases by John McMahon

If you love Apple TV’s espionage series Slow Horses (early in it’s 5^th season), this just might be your next read. Slow Horses is about British MI agents who’ve screwed up on the job, but not so grievous to get fired. Mostly considered incompetent. They get kicked downstairs to Slough House, hopefully to get so bored that they’ll quit or get killed on the job. If you have access to Apple TV and haven’t seen it, turn on Season 1 Episode 1 for no other reason than to see how the Slough House supervisor (played by Gary Oldman) is introduced and report back.

Head Cases might be considered the FBI’s version. The main agent is Gardner Camden, an exceptionally intelligent but socially awkward FBI agent who is particularly adept at recognizing patterns, solving puzzles, and connecting pieces of information that other investigators overlook. Gardner in the motor behind the FBI’s Patterns and Recognition (PAR) unit, a small group of unusual and similarly talented agents who are brought in to investigate cases that have resisted conventional police work. They work out of Jacksonville, FL field office because no one quite knows where to put them

Our story begins when the DNA of a murder victim connects the crime to Ross Tignon, a suspected serial killer who was assumed to have died in a deadly fire seven years earlier. Gardner had previously investigated Tignon and suspected him of several murders. To discover that Tignon had survived the fire and was (recently) alive immediately raises troubling questions about the thoroughness of Gardner’s investigation. Then, another suspected serial killer is found dead. The evidence suggests that the two murders are connected. Gardner and the PAR team realize they may be dealing with someone who is deliberately hunting other killers (What? Another book that can trace its basic plot back to Dexter?).

The investigation becomes an increasingly complex personal and dangerous when the murderer begins leaving clues and riddles specifically designed for Gardner to challenge him intellectually. At the same time, the PAR team faces the possibility that someone inside the FBI is providing the murderer with confidential information about unsolved serial-killer cases (shades of Serves Your Right recently reviewed here on MRB). Who can be trusted?  How to protect families and themselves? The FBI is a big organization.

Gardner may be brilliant, but he struggles with ordinary social interactions, making him different from the stereotypical action-oriented FBI hero. His only real human connection is with his young daughter, Camila. The other members of the PAR team are an entertaining ensemble of unique skills.

As police procedurals go, the author combines police investigation, serial-killer suspense, multi-layered puzzles, and some creatively interesting twists to keep the reader guessing. A little more back story might help readers connect with the PAR team.

Head Cases is both entertaining and intelligent that introduces us to an unusual FBI team, puzzling puzzles, unpredictable twists, and memorable protagonist. Give McMahon's Gardner a shot.
