Mrs. Grace Humiston was an amazing lawyer and a traveling detective during a time when no women were practicing those professions. She focused on solving cases no one else wanted and advocating for innocents. The first female US District Attorney, she made groundbreaking investigations into modern-day slavery, and the papers gave her the nickname of fiction's famous sleuth. One of her greatest accomplishments was solving the cold case of a missing 18-year-old girl, Ruth Cruger. Her work changed how the country viewed the problem of missing girls, but it came with a price: she learned all too well what happens when one woman upstages the entire NYPD. In the literary tradition of In Cold Blood and The Devil in the White City, this true-crime tale is told in spine-tingling fashion and has important repercussions concerning kidnapping, the role of the media, and the truth of crime stories. But the great mystery of this book - and its haunting twist ending - is how one woman became so famous only to disappear.
