An assassin thriller in which a paid kill turns into a personal crusade against a trafficking network. Hard-edged vigilante action that pits a killer’s warped code of honour against the ugliest trade on earth.

Some Jobs Are Personal. This One Became A Crusade.

Lachlan Byrn just couldn’t unsee it.

It began as a routine paid kill. Over the years, Byrn has turned looking away from problems that don’t concern him into an art form. So what’s different this time?

Byrn finds himself immersed in the sordid world of human trafficking, and as dark as the assassin’s nature is, the activities of the men he’s been charged with hunting don't sit well with him. His own moral compass, warped as it may be, is pointing somewhere new, and he intends to follow it no matter the personal cost.

Then comes a discovery that upends the entire job: Byrn is working for a dead man. Yet step by step, death by death, the crusade goes on.

You can’t keep a good man down… or a bad one.

He Without Sin is the third book in the Lachlan Byrn thriller series, for readers who love vigilante justice, antiheroes with a code, underworld conspiracies and relentless action. Perfect for fans of Lee Child, Mark Greaney and Tess Gerritsen.
