Jeanne Cleary’s eventual destination was the nursing school in London, but on her own for the first time she felt an urgency to sort out the mysterious circumstances of her birth. Born to an aristocratic French woman who had married against her family’s wishes, Jeanne had been left an orphan when her parents died during the war. Now, having just discovered the existence of her French grandparents, Jeanne was determined to have at least one look at her mother’s ancestral home. But Fate was not to be satisfied with just a far-away glimpse. Before she could turn away from the imposing Château de Clémenteaux, Jeanne would become entangled in a series of lies which would bind her to another’s identity … an identity which would keep her from the man she loved, and prevent her from unmasking the imposter who said she was the real Jeanne Cleary.
