An intelligence agent-turned-courthouse janitor, Paul McGrath notices everything and everyone—but no one notices him. Now he's discovered a missing file on Alex Pardew, the man who likely murdered McGrath's father but avoided conviction. Meanwhile, at the courthouse, he stumbles on the case of Len Hendrie, a small businessman who admits to torching a venture capitalist's mansion. As the Hendrie case is heating up, McGrath must return to his family home to confront unfinished business from his past, and in this follow-up to Invisible, he's about to find some unwelcome truths about the mother he lost as a child—and the father who hid even more secrets than he realized.
