Black Diamond 
(Bruno, Chief of Police #3)

In Saint-Denis, the "black diamond" truffle is a treasured asset, but reports suggest this unique delicacy is being adulterated for profit. Meanwhile, a family is attacked in the local market, and a former military man is found brutally murdered. Black Diamond takes us back to the irresistible atmosphere of rural France, while opening a window onto France’s colonial history in the company of beloved Chief of Police Bruno.
