Christian Foo Kune, owner of the palatial sugar estate Mon Trésor Mon Désert, catches his breath as he opens a gigantic safe in his office. We are in the midst of verdant canefields and blackened marshes lapped by an emerald Mauritian sea. I expect Foo Kune&rsquos profits from sugarcane&mdashone of Mauritius&rsquo main sources of income&mdashto tumble out. Instead, I see rows and rows of neatly stacked plastic tubs. They contain old bones, nestled in cottonwool and paraffin.
