Catch Me (Embryo: A Raney & Levine Thriller, Book 4) by J.A. Schneider is about the Couples Killer as the press called a serial killer who taunted the police with notes left at the scene.
David Levine & Jill Raney are well-developed characters. They have helped when the police have been at a loss. They have been targeted by this disguised killer & it's a race against time to catch him before he kills one of them.
This is an intense suspense-filled thriller. I gave it five stars.
