While wandering through a Paris auction house, avid collector Pierre-François Chaumont is stunned to discover the eighteenth-century portrait of an unknown man who looks just like him. Much to his delight, Chaumont's bid for the work is successful, but back at home his jaded wife and circle of friends are unable to see the resemblance. Chaumont remains convinced of it, and as he researches into the painting's history, he is presented with the opportunity to abandon his tedious existence and walk into a brand new life.

Chaumont needs a fresh start - he and his wife fell out of love long ago, and the only thing that holds meaning for him anymore is his search for perfect objects. But this portrait is more than just a painting. The first night he owns it, Pierre-François dreams of another life, lived as the Comte de Mandragore, in a rural chateau, with a beautiful young wife. Awaking from the dream he's determined to find this place - but it will take all his collector's avidity, ingenuity, and unscrupulousness to make it his own. And when he finally has the chance to do so, will he be willing to pay the price to make it last?
