Daring Deception. Hiatt Regency Classics, #4

He won a wife in a game of cards! Dashing Major Gavin Alexander, recently elevated to sixth Earl of Seabrooke, needs a fortune-fast! His new title came with a mountain of debt, and it is only a matter of time before he's denied entrance to the clubs where he's eking out a living by gaming. When Sir Thomas Chesterton cannot pay his losses at the table and offers his sister-and her inheritance-instead, Gavin jumps at the seemingly perfect solution to his troubles and agrees to wed Miss Chesterton sight unseen. No biddable spinster Frederica Chesterton is appalled to learn what her brother has done without her consent.
Determined to undo the bargain, she wrests a promise from Sir Thomas that if she can find proof Lord Seabrook is a rogue, he will release her from the betrothal. Without her brother's knowledge, Frederica infiltrates Lord Seabrooke's household as a frumpy servant to ferret out the man's secrets-and finds more of them than she bargained for! But even as she gathers her evidence against the handsome Earl, she finds herself perilously close to losing her heart.
Will revealing her true identity lead to disaster, or to a happy ending neither she nor Lord Seabrooke ever expected? Book 4 of Brenda Hiatt's bestselling Hiatt Regency Classics collection.
