Ancient secrets. Hidden danger. A lost masterpiece.

Darwin Lacroix seeks a tranquil year in Paris guest lecturing at the esteemed École du Louvre, but fate has other plans. Beneath the museum's grandeur lie secrets of a murky past.

A clandestine group formed in the Age of Enlightenment secretly controls the collections. During the wars, its unscrupulous curators conspired to squirrel away booty, cutting out the rightful owners. Billions in art: bought and sold for private gain. When French authorities pressure Darwin to expose the group's dark agenda, he pushes back.

But he soon discovers a terrible wrong done to his family that he must make right.

Trust is scarce. Danger constant in this deadly chase through the Paris underbelly.
