Yorkshire Dales, 1850. As a terrible storm rages, Annabelle Wallis is shocked to find a distressed young woman at her cottage door, heavy with child. Moments later a baby girl is born. But by dawn, the mother has vanished, leaving behind the helpless child wrapped only in a silk peacock shawl. When news spreads that Lady Eliza Hartley, sister to wealthy estate owner, John Hartley, has been found dead, Annabelle realises the terrible secret she has stumbled on. Terrified she'll be blamed for Eliza's death, Annabelle flees to the filthy slums of York, where she plans to raise the precious orphan as her own. The cobbled streets of York's slums are no place for a young woman like Annabelle or a Hartley babe and John Hartley is determined to bring them both home. But Annabelle proves impossible to find. Annabelle can't hide forever from the wealthy Hartley family, but can she ever give up the baby she loves?
