Paced like a thriller and full of insider information, this book embeds readers in one of the most famous true-crime stories of our generation—the kidnapping of Polly Klaas. On October 1, 1993, a 12-year-old girl was kidnapped at knifepoint from her bedroom in Petaluma, California, during a sleepover with two friends, while her mother slept soundly in the room next door. This rarest of all kidnappings—a stranger abduction from the home—triggered one of the largest manhunts in FBI history. New York Times bestselling author 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. With unprecedented access to case files, crime scene photos, a videotaped murder confession, and inside sources, In Light of All Darkness follows the investigators who pieced together the evidence that led to the arrest and conviction of the kidnapper—and made the victim a household name and a girl who will never be forgotten.
