The Lady’s Masquerade by Deborah Wilson

I love a good mystery, and a great romance. This story has both. Delia is no ordinary lady & Kieran is one strange Duke. They feel things together that are forbidden between a governess & a duke. Kieran has a sense of responsibility that will not allow him to marry the governess, although he is head of heels in love with her. Delia just wants to know who's responsible for leaving her sister dead on the road? This story has a great climactic ending ensuring a happy ending.
