Mark Greaney’s 10th Gray Man novel reads like an R18+ “Mission: Impossible” blockbuster, a pedal-to-the-metal action thriller that doesn’t let up from its opening, when CIA Poisoned Apple operative Zack Hightower is nabbed by goons from a Venezuelan intelligence service in a Caracas marketplace when he’s tracking a presumed dead (but actually treasonous) former NSA computer scientist.
When CIA deputy director for operations Matthew Hanley learns of Hightower’s failed mission he assigns fellow Poisoned Apple agent Court Gentry — the assassin formerly known as The Gray Man — to finish the job; nevermind the fact he’s still recovering from injuries suffered during a previous operation. But that’s the thing about action heroes: no matter how racked they are by pain and exhaustion, they always find a way — although Court’s rogues gallery has rarely been so substantial or lethal as they are in “Relentless.”
Bullets fly as Court faces off against American mercenaries working for the UAE, an unscrupulous international spy agency, and Russian agents hunting Zoya Zakharova, the love of Court’s life, and — you guessed it — also a Poisoned Apple asset. By now Greaney’s characters have enough flesh and blood to be convincing rather than mere gun-totting goons, and although he has a Clancy-esque eye for detail, narrative momentum never gets bogged down in the nitty-gritty particulars of the weaponry and gadgetry.
Greaney unabashedly delivers what fans of action-lit desire. Readers who desire the subtlety and subtext of John le Carré may cringe at the undulated carnage on these pages, but those who’ve been with The Gray Man since day dot will delight in it. This is grade-A action pulp, and I can’t wait for the next one.
