Born into the shadows of Victorian London, Mary Carr began her criminal career as a pickpocketing flower-girl, rising to be the undisputed Queen of the Forty Thieves. Under her rule, the Forty transformed from a band of violent, disorganised thieves into a ruthless, well-oiled gang, making a fortune from hotel robberies and blackmail. By 1891, Mary ruled Southwark, Lambeth, and beyond, her power extending from seedy back alleys to high society establishments. But Mary was more than just a criminal mastermind. A ‘swan-necked beauty’ and muse to esteemed artist Frederic Leighton, she navigated both the art world and the criminal underworld with ease. She was a revered gang boss and a beloved benefactor, caring for the families of imprisoned comrades and ruling with both generosity and iron discipline. This book unravels the legend of Mary Carr.
