There is only one John Douglas. We first met Douglas in Mindhunter, which told the story of his brilliant and terrifying with the FBI until his retirement in 1995. And now, again with coauthor Mark Olshaker, he goes even further. We accompany him on the Journey Into Darkness that marks every case he examines; every instance in which he helps police identify the unknown perpetrator of a violent series of rapes, kidnappings, or murders through his remarkable criminal personality profiling. In this fascinating audio experience, we journey with some of the brilliant and sensitive agents John has trained, who have carried on his work. We take a startlingly fresh look at the murders of Nicole Brown Simpson and Ronald Goldman as if John had been asked by the LAPD to identify the killer through behavioral profiling. And we hear how a lifetime around killers and their victims has shaped his views on justice and punishment. The Journey Into Darkness is a perilous one, but ultimately a hopeful one as well. For not only do we see from the men and women who track the most sadistic of criminals what a powerful weapon profiling has become, we also get advice on how we might better keep our children, our families and ourselves safe from harm. By making the Journey Into Darkness with John Douglas and his colleagues, we come away with an insight into the human condition that no one else can offer.
