The Duke of Somerset is soon to die, but he's not about to give up control of his family. He changes his will, forcing his son and heir John to remain under the authority of a man dissipated by alcohol and perversion, Lord Bartholomew, the Duke's brother.
When Bartholomew makes threats against the young woman John is supposed to marry and then challenges the betrothal, John take steps to protect Kitty. He forbids her from visiting the estate without her mother or father in attendance. He then assures her father Earl Raeburn that he intends to marry Kitty in three years, when he reaches his majority and takes control of the estate.
Uncle Bartholomew responds to this interference more violently than John anticipated. After two attacks against John's life, his mother decides it's no longer for safe for John to live on the estate. In the dead of night, they visit the gypsies, who have come to help with the harvest. After offering them a healthy bribe, they agree to flee the area, sheltering John in their caravan.
John hopes the letter he's left Kitty will sufficiently explain the situation, but it doesn't come close to meeting her romantic requirements of a love letter.
The three years pass much too slowly. John doesn't belong with the gypsies, and they never let him forget it. He misses his mother and Kitty, the only two people who ever showed him acceptance or affection.
He's finally ready to return to his estates, when he receives a visit from someone high in his majesty's government. The whole world is at war with Napoleon, but someone from the gypsy caravan is supposedly offering vital information to the enemy. If John wishes to save the gypsies, he'll have to prove their innocence. This means acting as a spy for the British government, something no gentleman duke would consider. When he doesn't return at the appointed time, it could also mean the end of his betrothal to Kitty.
Years later, John is almost ready to reveal the guilty parties, when he receives word that Kitty has decided to launch a Season in London. With his bride available on the Marriage Mart, John is convinced he can no longer wait to return to acceptable society. At the first big costume party, John attends dressed as a gypsy and falls instantly in love with his own fiancee. Knowing Kitty's desire for all things romantic, he begins a careful onslaught of her heart. Capturing her attention is easy, following through with the wooing whilst managing a career as a spy is not. If John isn't careful, he could lose a lot more than his estates. He could lose Kitty and his life.
