Avenging the Earl’s Lady by Alina K. Field

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. If he wanted a wife, she’d be perfect. Not to mention, he’d very much like her in his bed.
But she’s gone missing, along with a priceless painting he needs for revenge on one last enemy.
Avenging his own honor is everything—until that of his lady is threatened.
Find out what happens when the invincible Spy Lord meets his match!
