The Ripper Letter: The Heart of Darkness, cartea 1

Katherine Ramsland has played chess with serial killers, dug up the dead, worked with profilers, and camped out in haunted crime scenes. As a professor of forensic psychology and an investigative consultant (like her main character, Annie Hunter), she's always vigilant for unique angles and intriguing characters. She spent five years working with "BTK" serial killer Dennis Rader to write his autobiography, Confession of a Serial Killer, and has been featured as an expert in over 200 true crime documentaries. The author of 69 books, she's been a forensic consultant for CSI, Bones and The Alienist, an executive producer on Murder House Flip and A&E's Confession of a Serial Killer, and a commentator on 48 Hours, 20/20, The Today Show, Dr. Oz, Nightline, Larry King Live, Nancy Grace and other shows. She blogs regularly for Psychology Today and once wrote extensively for CourtTV's Crime Library. She's become the go-to expert for the most extreme, deviant and bizarre forms of criminal behavior, which offers great background for her Nut Cracker Investigations series.
