"Both my judgment and my conscience make me a Socialist. It's only one's wretched love for one's own little luxuries and precedences - the worst part of one - that makes me waver, makes me a traitor!" Marcella Boyce, a Pre-Raphaelite beauty of the 1880s, is passionately in love with the ideals of socialism. A 21-year-old art student, she lives in a Kensington boarding house until her father inherits the family estate, Mellor Park, in the Midlands. Leaving her studies, her philanthropic work in the East End, and the company of her Bohemian friends, she embarks on her new life at Mellor Park, determined to alleviate the poverty she sees around her. Then Aldous Raeburn, Tory candidate and heir to Lord Maxwell's estate, falls in love with Marcella. But Marcella is torn between her longing to become mistress of Maxwell Court and her burning idealism. Before she can reconcile the two, Marcella must learn - through bitter experience - the real barriers that divide one human from another.
