Dukes and Diamonds by Lauren Smith

Diamonds are a duke’s best friend…
When the infamously cold-hearted Duke of Helston decides to catch a gang of jewel thieves stealing from London’s elite circles, he never expects the thief to be a woman.
She’s not just any woman either…she happens to be the bewitching creature he met in the darkened corridor during a musicale who changed his life forever.
What’s a duke to do when he wants to catch a thief who not only stole his family diamond, but also his heart?
