From the Publisher:
Cory lied to Nameless about her livelihood, her relationship with Vorhees, her brother's alleged drug use, and the nature of his alleged crime. Not only is she Andrew Vorhees' mistress, Cory has a secret second lover, factory owner Frank Chaleen, with whom she conspired to frame Kenneth. This bizarre sibling betrayal is part of a diabolical plan that reveals her to be a deadly, designing woman who will stop at nothing to achieve her warped desires.
A series of twists and turns drive the story to a truly shocking climax. For not until then do the detectives realize how devilish Cory Beckett really is, a femme fatale who has brought something new to the species -- new, and terrible.
