Mark Greaney worked in international business before turning to fiction. He spent years traveling, observing the kinds of locations and situations that would later appear in his thrillers. The Gray Man was his first novel, published in 2009 and introducing Court Gentry, a former CIA operative turned freelance assassin.
Court Gentry kills people for a living. That’s the premise, and Greaney doesn’t flinch from it. The Gray Man series follows an antihero who does terrible things for money, occasionally stumbling into situations where his violence serves better purposes. The moral ambiguity is the point. Gentry isn’t a good person; he’s a person who sometimes does good things.
The books move fast. Greaney’s background in international settings shows in his globetrotting plots, which bounce between continents and pile on complications. Each novel reads like an action movie, heavy on gunfights and chases, light on introspection. Readers who want that get exactly what they’re looking for.
Netflix adapted The Gray Man in 2022, starring Ryan Gosling as Gentry. The film was one of Netflix’s most expensive productions. Reviews were mixed, but viewership was strong enough to greenlight a sequel.
Greaney also wrote several Tom Clancy novels, including entries in the Jack Ryan Jr. series. He’s comfortable working in both his own world and inherited franchises. The Gray Man remains his signature creation, with new installments appearing annually.
