Still recovering from the Ragdoll case, London Detective Emily Baxter is ordered to New York to assist when a copycat killer emerges in New York City. This time the body is contorted into a familiar pose, strung up from the Brooklyn Bridge, the word “BAIT” carved deep into its chest. Media pressure intensifies with a second victim, this one inscribed with the word “PUPPET.” As the murders grow in spectacle and depravity on both sides of the Atlantic, Baxter must shake off her grief and fear so she can stop the killer before it's too late.
