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

In 1917, an 18-year-old went missing in broad daylight. In 1905, a newly minted female lawyer took on a seemingly impossible case and won. Alternating between Ruth Cruger's 1917 disappearance and earlier cases, Ricca's vividly written narrative brings to life the groundbreaking work of attorney Mary Grace Quackenbos Humiston, who championed the rights of immigrants, the poor, and young girls. She often successfully made appeals to overturn wrongful convictions, saving several people from execution at the last minute. As a detective, she took on cases, such as Cruger's, that the police had abandoned, becoming the first female U.S. district attorney and, later, a special investigator with the New York Police Department. Though this is a thoroughly researched example of nonfiction, with extensive notes and bibliography, Ricca's storytelling ability easily allows readers to forget they are reading history instead of a novel. The descriptions of Humiston's work, with its tension and danger, offer a fascinating window on daily life and policing in New York in the early 20th century, and many of the causes she backed remain current social problems.
