[1] It is London in the late 18th century, and slavery has just been ruled illegal in England but is still common in the British West Indies.

Pedro's friends, Cat, Frank, Lizzie, Syd and the gang try to secure his freedom.

Cat finds trouble following her once more as she is chased around London by the Bow Street Runners, coming for her arrest for biting Mr Hawkins after he taunted her.

Disguising herself as a boy with the help of her friends, Frank and Charlie, she enters an aristocratic boarding school and learns Latin and fencing, things that girls are never taught.

When Syd arrives, he's furious and wants to take Cat home immediately, but soon realises that she's safe where she is as the Bow Street Runners are still looking for her.
