Brad Wallace's obsession with vengeance has cost him his marriage, his career, and his life. When he disappears beneath the surface of Lake Winnipesaukee, his former friends consider it a sad end to a life that went off the rails long ago. But Detective Parker Havenot isn't convinced that the self-proclaimed agent for justice would give up so easily. He and his wife, Josie Wallace Havenot, suspect that Brad faked his own suicide as a cover for whatever new vigilante acts he's planned. Investigating a series of strange and seemingly unrelated events, Parker discovers that Brad is not only alive, but working with Univac Redux, a company carrying out nebulous technological experiments. Can Parker connect the dots before Brad makes his next move?
