Ten years ago CSI Darby McCormick investigated a sinister child abduction case.
Today, the missing child is back from the dead and holding his family hostage.
He makes only one demand. Bring me Darby McCormick ...
Charlie Rizzo has his family at gunpoint and when Darby arrives to defuse the scene, she finds him horrifically mutilated, with a mask of human skin sewn in place over his own face. Within minutes, a group of men disguised as SWAT officers bursts in and releases deadly Sarin gas, killing the Rizzo family outright and leaving Darby herself barely alive.
Where has Charlie Rizzo been held all these years? Who are The Twelve who have been executing this gruesome torture? And why are the FBI running scared in the face of this particular, chilling episode? Darby is facing the toughest case of her career ... and, as the body count rises, one that will bring her into great personal danger and leave her in fear of losing her mind, if not her soul.
