Bad Move (Zack Walker Book 1), Linwood Barclay

Zack Walker is a writer with an overactive imagination and two teenage children. After a murder on their street, he uproots his family from the city - insisting it's for their own good - and heads for the security of the suburbs. However, his peaceful new life is soon shattered when he finds a body while out walking by the creek.

Zack recognizes the dead man - and knows who his killer might be. Things go from bad to worse as Zack follows a trail of deceit that leads right to his front door. To protect his family - and so he doesn't get framed for a crime he didn't commit - he's going to have to track down the killer himself.

Suddenly the suburbs are not looking nearly so safe . . .
