A Nashville woman's violent husband is presumed dead—until he makes a terrifying return in this thriller by the New York Times bestselling author. Leah Carson's husband Phillip made a promise to her once—that he would kill her. Four years ago, he nearly succeeded, stabbing her twenty-three times before fleeing. Now the police are sure Phillip is dead. But that doesn't stop Leah from checking and rechecking her locks. Especially when she can sense his attention closing in again. It starts with little things. Missing keys. A flat tire. Mysterious flowers. All easily explained away if the pattern wasn't so unnervingly familiar. Leah has a new life in Nashville with no ties to her nightmarish past. But when another woman's body is found, stabbed twenty-three times, Leah knows her past has found her. Alex Morgan of the Tennessee Bureau of Investigation knows there's more to Leah's story than mere paranoia. But as they untangle the horrifying truth, a killer is watching close, waiting for the perfect moment to make good on his promise... As Leah and Alex untangle the horrifying truth, he watches her, ready for the perfect moment. Until death —that was the vow they made. And a killer always keeps his word...
