About the series
Mark Greaney's Gray Man series follows Court Gentry, a former CIA paramilitary operative turned freelance assassin who lives by his own moral code. Nicknamed "the Gray Man" for his ability to vanish into any crowd, Court is the most dangerous man alive — and also one of the most hunted. The series is relentless, globe-spanning, and technically precise, drawing on Greaney's deep research into intelligence and special-operations tradecraft.

Begin with The Gray Man (2009) and follow publication order. The overarching storyline — Court's war with his former handlers and various global threats — develops across books, and character relationships deepen considerably from entry to entry. The 2022 Netflix film adaptation loosely draws on the first novel.
