Conrad Voort, the sexy and charismatic NYC detective, takes on a dangerously invisible killer in the most textured, complex and commercial Ethan Black thriller yet. . . Voort meets his childhood friend Meechum at a downtown bar for a drink and a disturbing conversation. His long-lost friend is paranoid and troubled, and vaguely hints at a military career gone terribly wrong . . . and then he suddenly disappears, and is later found dead under curious circumstances. A devastated Voort is left with only one clue: a list of names on a napkin that Meechum has asked him to investigate. One after another, Voort discovers that the people on the list are dead: victims of seemingly innocent accidents that begin to look more and more suspicious as the next comes to light. As he sifts through more information, Voort begins to uncover a mysterious plot masterminded by a former Army hero who is following a lethal agenda - - a plot involving a covert U.S. military operation targeting Americans suspected of terrorist leanings. Voort quickly learns that he must battle two enemies as they battle each other: one, a champion of valor turned cold blooded killer, and the other an ordinary man about to unleash a massive and deadly attack.
