Though Caroline was betrothed to the Duke of Winstrop, she loved the stableboy William. And so when her father had him executed on a contrived charge of treason, she secretly had his heart removed from his body and stitched into it every one of the love notes he had written her. On her deathbed years later, the Duchess of Winstrop told her daughter she would learn the true identity of her father if she searched her heart.
