Book excerpt: In the tradition of her acclaimed mother, Ann Rule, author of The Stranger Beside Me, bestselling author Leslie Rule exposes the trail of a sadistic sociopath, identity thief, and killer . . . It was a bleak November in 2012 when Cari Farver, thirty-seven, vanished from Omaha, Nebraska. Texts sent indicated that the hardworking mother had quit her job, abandoned her son, and cut ties with everyone. Cari’s boyfriend, Dave Kroupa, accepted the breakup at face value. Her mother, Nancy Raney, however, had doubts. “I need to hear your voice,” Nancy begged. When the texter refused to speak, Nancy reported Cari missing. While no one saw or spoke to Cari, more than 12,000 sinister emails and texts were sent in her name over the next years. Police believed Dave and his girlfriend, Shanna “Liz” Golyar, when they reported that the missing woman was cyberstalking them. The tormentor was eerily aware of Dave’s every move, knew when Liz visited and threatened the couple. It never occurred to Dave that Cari was a victim—that the real stalker had killed before, and was planning to kill again. Leslie Rule tracks the heart-pounding path to long-awaited justice—from a twisted past to the deadly deception and the high-tech forensics that condemned the killer to prison. “Rule's first true crime book hits the mark.” —Katherine Ramsland, author of Confession of a Serial Killer: The Untold Story of Dennis Rader the BTK Killer “A deft, fascinating true crime story of obsession.” —Library Journal (Starred Review) With a New Update by the Author Includes Reading Group Guide
