Mist of midnight

Rebecca Ravenshaw, daughter of missionaries, spent most of her life in India. Following the death of her family in the Indian Mutiny, Rebecca returns to claim her family estate in Hampshire, England. Upon her return, people are surprised to see her-- less than a year earlier, an imposter had arrived with an Indian servant and assumed Rebecca's name, home and incomes-- and died within months of her arrival. Everything reverted to a distant relative, Captain Luke Whitfield. If Luke is simply after the property, will she suffer a similar fate as the first "Rebecca"?
