I somehow missed this book last year, I ended up meeting the author at ALA, and she kindly signed a copy for me. In my, before kids life, I worked at a small police station answering 911 for the police and fire of the surrounding towns. At the time, the girls worked in the office, and the guys were all cops, and that was the late 80's. This obviously goes much farther back in time to cities that although slow to accept women in these careers did so well before my time.
From the times of jail matrons and those women who were among the first to be on patrol, be a detective, and a police chief we are shown what it was like moving up the ranks. We also learn about women in various forensic careers--like a forensic artist and crime scene investigation--and federal organizations like the FBI, US Secret Service, and customs inspections. It's a complete look at the history of women in law enforcement.
Each chapter concludes with links to learn more about each woman/subject. I especially enjoyed the sidebar about Mary Holland who along with her husband ran a detective agency in Chicago around 1912. She was one of the world's first fingerprint experts.
I'd love to pass my copy along to a female teen interested in law enforcement. If you have someone in mind comment here or DM me over on Twitter.
