You never really know what demons people are battling against". A phrase that optimises this story. Not just the people in this book, but people in every walk of life with everyday struggles. You have to understand that in early 2000's people didn't really talk to each other as they do now or share their feelings as freely. A team of cops have been given the run around by a serial killer and to be honest they're struggling to catch him - even find a lead. David Jennings is a workaholic cop who leads this team to try and catch this killer but not is all as it seems.
