Invisible

Paul McGrath rebelled against his pacifist father by becoming a stand-out Army recruit, the star of his military intelligence unit. When he returns home, it's to find his father dead, seemingly murdered-- and the trial ending in a hung jury. So McGrath put his arsenal of skills to work to find out just how corrupt the legal system was. A job at the courthouse-- as a janitor-- is the perfect cover, giving him security clearance and access to the entire building. He notices when witnesses suddenly change their stories. When jury members reverse their votes during deliberation. He can't bring back his father-- but McGrath can right current wrongs and save others. -- adapted from publisher info
