Tell Laura I'm Back

But how can detective Laura enjoy that vacation with her boyfriend in the Bahamas when the Westervill serial killer she's sure she has ended, over a year ago, starts stalking her in her dreams, telling her he's back? And coincidentally, these nasty assassinations start to happen again in Westerville just the way they were happening over a year ago. That serial killer possibly couldn't be alive. And why he keeps stalking Laura in her dreams? Is it really a coincidence? Someone is having some brutal fun and obviously getting away with it.
Times running out, and whosever is playing this game obviously has a daily target. The authorities are clueless. Could the only surviver of the brutal Westervill attacks be of any help in putting all of this to an end?  And, will Laura adhere to the strick instructions from her superiors in the police department to remain on her vacation while all of this is happening back home in Westervill?
