On March 18, 1990, thirteen works of art today worth over $500 million were stolen from the Isabella Stewart Gardner Museum in Boston. It remains the largest unsolved art heist in history, and Claire Roth, a struggling young artist, is about to discover that there’s more to this crime than meets the eye.

Making a living reproducing famous artworks for a popular online retailer and desperate to improve her situation, Claire is lured into a Faustian bargain with Aiden Markel, a powerful gallery owner. She agrees to forge a painting—a Degas masterpiece stolen from the Gardner Museum—in exchange for a one-woman show in his renowned gallery. But when that very same long-missing Degas painting is delivered to Claire’s studio, she begins to suspect that it may itself be a forgery.

Her desperate search for the truth leads Claire into a labyrinth of deceit where secrets hidden since the late nineteenth century may be the only evidence that can now save her life.
