1648 – Hertfordshire. Thirteen-year-old Katherine Ferrers is in despair at being betrothed to arch-Royalist Thomas Fanshawe whose family are hellbent on plundering her family’s fortune to champion the exiled Charles. As her unhappy marriage stretches before her, her only comfort is her beloved childhood home The Cell. But as the years pass and Kate grows restless, a new passion, a new love and a dangerous calling threaten to upend everything she’s ever known. Present Day – Hertfordshire. Charlie Wolfe jumps at the chance to help his uncle renovate a tumbledown cottage overlooking Nomansland Common. Number One Constable’s Cottages was once the home of the man charged with ridding the common of the highwaymen who terrorised travellers. But it’s the story of The Wicked Lady, the notorious female highway robber, that captures Charlie’s imagination, and some long winters’ nights he’s sure he can the hoofbeats of her horse echoing across time. What drove this mystery woman to risk everything for a life of crime, and why is she still restless, wandering the common in grief? It seems only Charlie can finally uncover the secret Katherine Ferrers has kept for hundreds of years; a secret of a terrible betrayal and a tragic love that was never meant to end this way.
