An ambitious reporter seeks a window into an obsessed killer’s mind—and is forced to take a hard look in the mirror, in this dark psychological thriller. It starts when a Cornwall fisherman finds a body in the ocean. The blood of the victim has washed away, but the angry message etched deep into the victim’s back is crystal clear: Grace—Number 1. It’s the kind of story that could make local reporter Jennifer Mack’s career—if she can keep her hypercompetitive colleague, Hayley, from undermining her at every turn. When the next body turns up far away in London, another carved message makes the link unmistakable—a serial killer is on the loose. Then, Jennifer receives a package from the killer. As she begins to communicate directly and publicly with a murderer-at-large, it appears she’s been chosen to write the headline story. But as lines between right and wrong start to blur, Jennifer is forced to come face-to-face with her own inner darkness . . .
