A truly evil serial killer ‘hell-bent’ on accomplishing his brutal agenda unleashes his venom. Boston’s leaders are not prepared for this breed of killer; ruthless, methodical, and with a taste for the ancient ways. As they flounder, the Watchmaker, a sleuth with an unmatched record for routing out serial killers, is forced upon them. Dr. Edward Dunham, FBI’s chief scientist, soon becomes aware this elusive adversary is different; quite possibly out of his reach. The killer’s brutality and intelligence are unbelievable, almost otherworldly. The Watchmaker, a man guided by naturalistic methodology, realizes he must stretch these boundaries in order to end the fiend’s terror.
