Head Cases By John McMahon

Discovering a new author is always a thrill, and John McMahon's Head Cases is a superb thriller that you must earmark as a must-read for 2025. The characters, led by FBI Agent Gardner Camden, form an eclectic group that you will cheer for and laugh with as they unravel clues leading them along a winding path to a serial killer. Head Cases is a splash of Monk, a twist of NCIS, and a dabble of a pure Hercule Poirot murder mystery. McMahon's creative writing will keep you up for hours, as you won't want to put it down.

When DNA links a murder victim to a serial killer long presumed dead, the FBI’s Patterns and Recognition (PAR) unit is called upon to solve the mysterious clues left behind. Alongside Gardner, the PAR team consists of a mathematician, a weapons expert, a computer analyst, and their leader, a seasoned agent. With an enigmatic case that will keep readers on the edge of their seats and this quirky collection of characters, Head Cases is an unmitigated success. If this is the debut of a series, I can't wait for the next PAR/Gardner Camden thriller.
