"Her mother is brothel madam Helga, but Winter isn't keen to become part of the family business. An independent, pragmatic scavenger, she and other street urchins make a living by beachcombing on the banks of the Thames. She isn't afraid to loot a dead body whenever one washes ashore." 
Winter was a resourceful, independent young girl planning to build a better future than that offered to women in the slums. Despite her strange sense of reality, including the belief in the supernatural, Winter was a disillusioned individual, hardened by street life.
Winter was a teenager with curly black hair and tomboy attitude and clothing. Given the fact that she was of mixed heritage, it's likely that her father was black or of mixed heritage as well.
Background Winter was a young girl with a strange and dark sense of reality. She was the daughter Helga had with an unidentified man, raised in the streets of London committing theft to the detriment of passers-by and corpses.
A Mudlark in London
Nights later, Winter warned James Delaney about a potential hit man hired by Helga to kill James and regain full control of warehouses at the docks. The girl pointed to a moored ship as the hiding place of a hitman and accompanied Delaney on board a boat, where she asked the man information on Africa and America. After Delaney had gone to check on the ship without finding anyone, and after putting fire to it, Winter had disappeared from the boat. 
Winter, along with two wretched children, was on the beach to plunder corpses. Later, she was hidden in the cellar of the Delaney mansion and offered to James the silver tooth stolen from the corpse of the Malay who had tried to kill James himself. At this point Winter asked James to teach her magic so that she too could turn into a wolf or even better into a bird, to fly away. Winter also said she was aware of the significance of the symbol marked between James' shoulder blades, a Sankofa (tribal bird). James advised Winter to return to her mother, Helga. 
Several days later, Winter was behind the counter of her mother's tavern and was invited by James to find her to discuss business. 
When the soldiers came to annoy the true pleasure than Helga's brothel in search of information on the robbery to the warehouses of the East India Company, Winter shouted for French Bill and Atticus to intervene. Later, she was appointed by Atticus to spread the word on what happened to those who came with wrong questions in the area, without blinking before the soldier's corpse thrown on the shore. 
Winter sought James Delaney's company at the docks, but the man drove her away several times, frightening her with disturbing stories about the African Devil, the only thing that scared Winter. Later, after witnessing an argument between her mother and James at the Tavern, Winter tried again to comfort the man during a hangover for losing his ship, and the next morning James woke beside Winter's mauled corpse.
