Disguise is a dangerous game . . .

After a lifetime as a wallflower Harriet, the Duchess of Berrow, is finally seeking a little pleasure of her own. And where better to begin than at the house of one of the most disreputable men in the country, Lord Strange?

However, the high-stakes games of lust and chance that rule Strange's household mean that to cross the threshold could entirely ruin her reputation. So Harriet swaps her hoops and corsets for a pair of breeches and transforms herself into a young male relative of the Duke of Villiers.

Before she knows it she's writing bawdy missives on behalf of a young actress, not to mention winning card games played by the most powerful men in England.

But when she starts attracting male attention, Harriet must decide whether to stay in her disguise - or to reveal that she's really a duchess by night . . .
