I can't make my mind up about this one - The premise is interesting and it has the makings of a great twist-filled thriller......BUT.....do I really want to read another thriller about people who don't have to worry about getting the day off from their job in a supermarket to dash off halfway across the country because a new lead's come up? Or who have to empty the washer and do normal stuff rather than being thrown from gilded middle class/wealthy lifestyle simply because it adds glamour or an idea of 'so much to lose'...........
