Mrs. Sherlock Holmes: The True Story of New York City's Greatest Female Detective and the 1917 Missing Girl Case That Captivated a Nation

Grace Humiston was a lawyer, a detective, and the first female U.S. District Attorney. She was also a society woman who would become one of the greatest crime-fighters in America. This is her story.

In 1917, on the day before Valentine's Day, a beloved teenager named Ruth Cruger went missing. When the police gave up on trying to find her, Grace took it upon herself to get the job done--even if that meant navigating a dangerous underworld of secrets and lies, two-faced cops, and a mysterious pale man in a desperate race against time to bring Ruth home.

Grace's motto--justice for those of limited means--led her to investigate some of history's most notorious cases, in New York City and across the globe. Mrs. Sherlock Holmes is the first-ever narrative biography of this singular woman the press nicknamed after fiction's greatest detective.
