Lord of Tresarnack — Elisabeth Barr

In order to rescue Emma from a life of misery with her cousin Alberta, Jago claimed that she was a wealthy heiress, and that he had been appointed her guardian. Later, he ruefully admitted to Emma that he was, in fact, as penniless as she was, having been disinherited by his uncle but Emma, in gratitude for his kindness to her, insisted on helping to find the missing will that would show him as the rightful heir to the Tresarnack estates. To do this, she travelled to Cornwall, posing as a lady's maid to gain entrance to Tresarnack Castle, where her benefactor's cousin the cruel and wily Dauncey lived with his mistress, the notorious Crystal Camden. It was a very dangerous assignment, and victory would have to be achieved before Emma could look forward to a lifetime of love and happiness
