Billionaire Genoa Greeves believes the LAPD should finally solve the fifteen-year-old execution-style murder of her favorite teacher, Bennett Little—especially now that Hollywood music producer Primo Ekerling has been slain in an eerily similar manner: shot and stuffed into the trunk of his Mercedes-Benz. Lieutenant Peter Decker resents having to commit valuable manpower to a cold case simply because a rich woman says, "Jump!" But when a primary investigator in the Little case, now retired, suspiciously commits suicide hours after he and Decker talk, the detective realizes something evil's connecting the dots in two murders separated by a decade and a half. Wife Rina Lazarus offers a cool, rational outlook, as always, despite her growing concern for her husband's welfare—as past and present collide with a vengeance, catapulting Decker ever closer to the edge of an infinite dark abyss.
