The Cornish captive

Cornwall, 1800. Imprisoned on false pretences, Madeleine Pelligrew, former mistress of Pendenning Hall, has spent the last 14 years shuttled between increasingly destitute and decrepit mad houses. When a strange man appears out of the blue to release her, she can't quite believe that her freedom comes without a price. Hiding her identity, Madeleine determines to discover the truth about what happened all those years ago. Unsure who to trust and alone in the world, Madeleine strikes a tentative friendship with a French prisoner on parole, Captain Pierre de la Croix. But as she learns more about the reasons behind her imprisonment, and about those who schemed to hide her away for so long, she starts to wonder if Pierre is in fact the man he says he is.
