Cross over - james patterson

Detective Alex Cross hunts down a serial killer who targets entire families--and who will next be coming for the Crosses.

A methodical killer is targeting multigenerational families in and around Washington, DC--striking under cover of darkness, triggering no alarms, leaving no physical evidence of any kind.

Alex isnt the only one investigating.

Also on the case is a charismatic true-crime author who sees patterns the detectives miss.

The writer calls The Family Man a perfect crime story.

Alex knows there is no perfect crime--the investigation should never become the story.

Unless the ending falls somewhere between fact and fiction.
