Black Diamond

France’s Périgord region is the home of the black truffle and at five thousand euros a kilo, the exquisite ‘Black Diamond’ is a treasured local asset. When reports come in that this unique delicacy is being adulterated with a cheaper Chinese version, Captain Bruno Courrèges is asked to investigate the scam. But matters take a much darker turn when a horrific murder occurs, and Bruno has his work cut out to find the connection between present crimes and long-buried ones that are linked to France’s colonial past.
