Vanitas book by Joseph Olshan

The moment that Sam Solomon casts his eyes on a stunning erotic drawing that hangs in the apartment of a dying art dealer, he finds himself caught in a tide of confusion and longing. Sam suspects that the drawing, called 'Vanitas', has a dramatic story behind it that might answer questions that the art dealer has refused to the story of a once tragic love affair, what happened to the artist who created the drawing, the events surrounding a falsely authenticated 19th century painting that nearly destroyed the art dealer's career.
