Dead Ringers (Unabridged‪)‬

A vicious serial killer is haunting the bayous of Louisiana, and the only person who can catch him is F.B.I. Agent Kate Palmer. But after years spent thinking like serial killers in order to catch them, Kate is finally facing burnout. To make matters worse, she's just about to rekindle a relationship with the only man she ever loved when the Bayou Butcher strikes again, this time terrifyingly close to home. For Kate, that makes it personal. And it might also be just the thing it takes to break her completely.
