Invisible. A Novel

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."Propulsive and engaging from the very first page."-C. J. Box, #1 New York Times bestselling author of the Joe Pickett series As a young man, Paul McGrath rebelled against his pacifist father by becoming a standout Army recruit and the star of his military intelligence unit.
But lingering regrets about their relationship make him return home, only to find his father dead, seemingly murdered. When the case ends in a mistrial-after a key piece of evidence disappears-something doesn't smell right to McGrath. So he puts his arsenal of skills to work to find out just how corrupt the legal system is. And to keep digging, he gets a job at the courthouse. But not as a lawyer or a clerk.
