On October 1, 1993, 12-year-old Polly Klaas was kidnapped at knifepoint from her bedroom in Petaluma, California, during a sleepover with two friends. This rarest of all kidnappings --- a stranger abduction from the home --- triggered one of the largest manhunts in FBI history. The emotional gravity of Polly’s story touched every agent, police officer and forensic technician who worked on her case. Many of these investigators have never shared their stories --- until now. Kim Cross has written the first comprehensive account of what happened on that fateful night in October, as well as how the case forever transformed the Bureau’s approach to solving crimes.
