This book was written by an investigative reporter. It tells the true story of the search for a serial killer who is still out there somewhere. At last count there are at least five women who were found in an area of Long Island called Oak Beach. The families of the women have a theory as to why these cases are still unsolved : the women were all involved in Internet prostitution. The book really explores the shady world of escorts and the way that technology, by way of Craigslist and Backpage, has made prostitution dangerous in a whole new way.
