To Key A Marquis is a romantic, mystery, adventure novel of England beginning in 1708. During the years of Queen Anne's reign, the increased tension of the ongoing political battle between the queen and her lifelong friend, the Duchess of Marlborough, brought an impassioned intrigue to bear upon two courtiers who found themselves pawns in that struggle. Landing in the midst of that controversy would take all of their wit, acumen, and skill to extricate themselves without total personal destruction, and in doing so the added requirement of an exceptional ability to manipulate two tenaciously powerful women. It was the era when England would become mistress of the seas.
