The cases that haunt us: [from Jack the Ripper to JonBenet Ramsay, the FBI's legendary mindhunter sheds light on the mysteries that won't go away]

Confident in his opinions and systematic in his examination of high-profile whodunits, FBI veteran John Douglas proves his worth once again as one of the world's best psychological detectives. You may think you've read all there is about Jack the Ripper, Lizzie Borden, and the Lindbergh kidnapping, but Douglas has a few surprise conclusions in his modern analysis of these gripping crimes. By applying criminal personality profiling techniques he developed while stalking more current killers, Douglas provides a fresh, sage outlook on some disturbing history. He also sheds new light on San Francisco's Zodiac Killer, the Black Dahlia murder, Bambi Bembenek, the Boston Strangler, and the continuing mystery of who killed 6-year-old JonBenét Ramsey. Douglas sometimes reveals his chief suspect; other times he simply narrows down who the killer is not. In the JonBenét mystery (in which Douglas was hired by the Ramseys to find the killer), he presents a convincing case for why he believes the girl's parents are not guilty of murder. Douglas is founder of the FBI's Serial Killer Profiling Unit. His method of solving a crime by entering the mind of the killer inspired Thomas Harris's book The Silence of the Lambs. In this dissection of our most sensational crimes, Douglas proves that reality can be more horrifying than fiction. --Jodi Mailander Farrell
