The only beautiful thing in Ivy's drab life is her glorious red hair. At a young age, her locks made her the target of Carroty Kate, a 'skinner'. She recruited Ivy to help her coax wealthy children away from their nannies so that she could strip them of their clothes - clothes worth a fortune in the markets of Petticoat Lane. It is years before Ivy escapes and finds her way back to her in-laws. Once there, she finds respite in laudanum. But before she can settle into a stupor and forget the terrible things she has done, Ivy is spotted by a wealthy pre-Raphaelite painter.

Realising quickly that this painter has more money than sense, Ivy's in-laws order her to sit for him, and to do anything else he demands. But not everyone is happy. Oscar's mother is determined to get rid of Ivy. Oscar's famous neighbour is determined to paint her. Carroty Kate is determined to find her, and Ivy herself is determined to escape...
