An Army veteran and intelligence agent goes undercover as a janitor at a federal courthouse to pursue his own brand of justice in a thriller that's part John Grisham, part Robert Crais.

When Paul McGrath was a young man, he rebelled against his pacifist father by becoming a stand- out Army recruit, the star of his military intelligence unit. But lingering regrets about their relationship made him return home, only to find his father dead, seemingly murdered. And when the murder trial ended in a hung jury—with just one hold-out among the jurors—something didn't smell right to McGrath. So he put his arsenal of skills to work to find out just how corrupt the legal system was. And to keep digging, he got himself a job at the courthouse. But not as a lawyer or a clerk.

Now McGrath is a janitor. The perfect cover, it gives him security clearance and access to the entire building. No one notices him, but he notices everyone. He notices when witnesses suddenly change their stories. When jury members reverse their votes during deliberation. When armies of corporate attorneys grind down their small-time adversaries with endless tactical shenanigans. And while McGrath knows that nothing he discovers can undo his past wrongs or save his father, he finds his new position brings him something else: the chance to right current wrongs and save others. And by doing so—just maybe—to find redemption for himself.
