The lily in the snow / Jackie French.

With her dangerous past behind her, Australian heiress Sophie Higgs lives in quiet comfort as the new Countess of Shillings, until Hannelore, Princess of Arneburg, charms the Prince of Wales. He orders Sophie, Nigel - and Miss Lily - to investigate the mysterious politician Hannelore insists is the only man who can save Europe from another devastating war. His name is Adolf Hitler. As unimaginable peril threatens to destroy countries and tear families apart, Sophie must face Goering's Brownshirt Nazi thugs, blackmail, and the many possible faces of love. And then the man she once adored and thought was lost reappears, and Sophie must also confront a vengeful girl, intent on killing the woman she believes is her mother: Miss Lily.
