Outsmarting the famous Holmes brothers.

On her fourteenth birthday, Enola Holmes wakes to discover that her mother has mysteriously vanished. When her famous older brothers, Sherlock and Mycroft, arrive intent on packing her off to a finishing school to learn proper Victorian decorum, Enola gives them the slip.

Disguising herself and escaping into the dark, labyrinthine alleys of London, Enola stumbles headfirst into a kidnapping case involving a young marquess. Using her own brilliant detective skills and secret codes, she races against time to solve the mystery while staying one step ahead of her legendary brothers.
