Through an Unlocked Door] is a unique look (I don't know of another book quite like it) at the crime of murder occurring in the homes of those who, through a matter of conscious decision or simply not paying attention, failed to secure their homes and to lock their doors, and because of this, were easily slaughtered. It is both an in-depth look at those killers who went out of their way to find the unlocked doors, and those who suffered because of it. Indeed, the issue of the unlocked home crosses all societal, economic, and cultural lines; and can be found in abundance throughout all 50 U.S states. And this book is an attempt to bring this ""hidden"" problem to light, so that those who have had an issue with securing their dwellings, will make the proper changes, and in doing so, will greatly reduce their chances of becoming a homicide victim.
