In The Vanishing Man by Charles Finch, the 15th Duke of Dorset, one of the most powerful noblemen in Great Britain, wants to know who stole a painting of his ancestor from his study. The Duke's concern is not for his ancestor's portrait; hiding in plain sight nearby is another painting of infinitely more value, one that holds the key to one of the country's most famous and best-kept secrets.

As the Dorset family closes ranks to protect its reputation, Lenox uncovers a dark secret that could expose them to unimaginable scandal. The family is willing to risk anything to keep hidden the existence of an artifact, priceless beyond measure.
