Pure & Unadulterated.
When Harriet, a young girl who, with her friend Mary, has left her coastal job of collecting and gutting fish, stops on a bridge in her newly adopted home in York, she is approached by an upper-class gentleman.
Samuel is a Quaker, a good soul, and a man interested in the new science of photography. He collects photographs of working-class girls in their working clothes. Samuel invites the girls to come to his friend's studio. While Mary is almost instantly lost to the art of photography, Harriet goes on to get a job in the Quaker-owned Wetherby's Cocoa Factory.
She soon catches the eye of a young clerk who is one of the favourites of the owners and through him discovers the deadly rivalry between the chocolate-makers. Samuel is also taken with the young Harriet, though because of his class, he watches her from afar, until his sister - 'mad Grace' locked away in an asylum - becomes part of their mutual story.
