Nick Heller likes nothing more than being underestimated by an opponent. He’s self-deprecating, irreverent, a man who can’t stand pretense. Or bullies. He really doesn’t like being lied to — and no one’s more loyal. After serving in the Special Forces in undisclosed locations, doing things he’s not allowed to talk about, he became a “private spy.” Now he’s got his own boutique international investigation firm in his hometown of Boston. And as some very bad people are about to learn, he never, ever gives up.
