Avenging the Earl's Lady

He's the most irritating, inscrutable, insufferable lord in the kingdom. Also nosy, managing, and manipulative, and a man who's made an art of revenge. She ought to know better than to encourage his attentions. But...he's rich, and when an impossible debt from her past comes due, theft seems the only answer. What had he missed about her? She's nobly born, and proper, and if--or when--he wanted a wife, she would be perfect.
Yet though the long war is over, honor requires vanquishing one last enemy before making time for romance. But when the lady he longs for disappears with a priceless painting and interferes with his plot, his enemy strikes at her. And then nothing else matters but avenging his lady.
