When Nora Ashford visits her mother in their historic Connecticut home, she expects the usual family tension—not a hidden portrait worth millions and a mystery spanning two centuries. The discovery of Catherine Ashford's painting unleashes long-buried secrets involving a priceless sapphire, a blackmailer from the French Revolution, and her father's suspicious death in 1985. With help from a mysterious appraiser and a sharp-tongued archivist, Nora must untangle generations of lies before the truth—and those who killed to hide it—destroy her family forever.
