Maude Foster

Maude Foster was a pickpocket who operated in London during the victorian era.

Foster was known to be one of the fastest pickpockets in London, capable of cutting the purse of any desired target and getting away with it, despite her lack of stealth. At some point, Foster joined London's biggest street gang, the Blighters.

By 1868, the Metropolitan Police Service had taken an interest in Foster. Sergeant Frederick Abberline, who had allied himself with the Assassins, met with Jacob and Evie Frye, requesting their help in bringing Foster in.

The Assassins located Foster in a small park near St. Paul's Cathedral, in the City of London, from where they kidnapped her before delivering her to Abberline.
