The Midwatch Institute for Wayward GirlsThe Midwatch Institute for Wayward Girls

Maggie, an orphan, is sent to the dreary Midwatch Institute, which is actually a secret training ground for young girls learning skills to fight crime; she and her new friends learn useful lessons, uncover a city mystery, and work together to solve it.
"Maggie Fishbone is not expecting much when she's sent to the Midwatch Institute for Orphans, Runaways, and Wayward Girls - the last resort after causing a ruckus at the orphanage where she was living. Except... the Institute isn't some dreadful, dreary place like she thought. Instead it's full of curious girls training to solve mysteries, fight bad guys, and keep the city safe. In between fencing lessons and discovering all the shortcuts in the building, Maggie finds herself making friends at the Midwatch and finally feeling like she's home. And when a woman goes missing, Maggie's off on her first assignment, with each step leading her deeper into the secrets of the city."--Publisher.
