Mrs. Sherlock Holmes

When 18-year-old Ruth Cruger disappeared in 1917, newspapers reported that she probably ran off with a boyfriend. New York police said that there were no clues to go on. But an investigator named Grace Humiston decided that she would do whatever it took to find her. She became known as "Mrs. Sherlock Holmes."

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