Some are born with a perfect palate, others with perfect pitch. Lily Sparks was born with a perfect eye. As Conservator of Paintings at the Denver Art Museum, she uses her keen visual powers to restore masterpieces and detect what's authentic and what is not. When the museum's billionaire benefactor is brutally murdered and Lily is dragged into the case, the grisly tableau stuns her: it's the human embodiment of the museum's prized landscape by famed Impressionist Gustave Caillebotte. Lily comes to believe the Caillebotte was forged and the killer is a painter the art world spurned. But this knowledge comes at a terrible cost. As she confronts where art ends and fraud begins, she must face the deceptions in her own past.
