The narrative follows Red on her incredible life-journey as it twists and turns through poverty, riches, infatuation, loss and love.
A dramatic escape from the workhouse at thirteen propels Red into a world of slum housing, street gangs, prostitution and petty crime as the rapidly expanding city groans under the weight of the industrial revolution.
A chance meeting with the mysterious and eccentric Sherlock Holmes prompts an infatuation which cuts through her street-wise bravado. Reds blossoming criminal career also brings her to the attention of Professor James Moriarty.
An autistic savant riddled with obsessive compulsions, Moriarty is a dangerous criminal who draws Red into his life and onto a collision course with Holmes.
