The fatal flaw

When a young woman wakes with no memory of her identity, she is told by Charles Buckler that he has rescued her from a vicious attack during her journey to Ridgeworth to become the intended bride of his distant cousin, Sir Ashton Buckler. An impostor has taken her place, however, and she must resume her rightful position. Who can Elinor believe? Is Charles all he seems? What happened to Sir Ashton's first wife - and why does someone at Ridgeworth resent her presence?
