The harrowing scene is always the same: the home of a single woman, no signs of forced entry, no evidence of an intruder, and no victim - only a bathtub filled with blood. Newly promoted homicide detective Angel Alves wants to make his mark in the department and a difference on the streets, but tracking this elusive serial killer sorely challenges his commitment and skills. Meanwhile, assistant DA Conrad Darget has his own hands full mentoring an ambitious young law student and rallying his fellow attorneys in their daily courtroom battles. With each new attack the twisted mystery only deepens, and the hunger for answers - and action - intensifies. No sane mind could comprehend the dark design behind it all. And no one can anticipate the final fateful strokes that will lead to a shocking endgame.
