In this eagerly awaited new book by the international best-selling authors of "Mindhunter" and "Journey into Darkness, " master FBI profiler John Douglas takes us into the minds and souls of both the hunters and the hunted. The legendary former head of the FBI's Investigative Support Unit, Douglas was the pioneer of modern behavioral profiling of serial criminals. In "Mindhunter, " we followed his development into a modern, real-life Sherlock Holmes as he tracked down the Atlanta child murderer, San Francisco's Trailside Killer, and Seattle's Green River Killer -- a chase that nearly cost him his life. In "Journey into Darkness, " he directed his unique skills particularly to crimes against children and young adults, and showed how the quest for closure for the survivors does not always end simply with catching the killer.

He plumbs the minds and motives of those who commit these terrifying and seemingly inexplicable offenses, using as examples his study of Ed Gein, Gary Heidnick, and Ted Bundy, the three obsessional killers who made up the composite character of "Buffalo Bill" in The Silence of the Lambs.

But Douglas also looks at obsession on the other side of the moral spectrum: his own career-long obsession with hunting these predators; the obsession of the directors of a model police department's victim's program in Virginia that has literally saved the lives of survivors; and the obsession of a brilliant young lawyer who has established an innovative school in Harlem to combat crime, drugs, and despair. Finally, there's the poignant and moving story of Gene and Peggy Schmidt and their daughter, Jennifer, whose sister, S
