Black Diamond - Martin Walker

A the heart of French gastronomy lies the famed black truffle of the Prigord. But France's truffles are being adulterated with cheaper ones from China, and it seems that Chinese organised crime is behind the fraud.

In St Denis market, a Vietnamese family has been selling their dishes for years, until their stall is wrecked by attackers who look Chinese. Again it appears that organised crime is behind the outrage, firing the opening shots of a Viet-Chinese triad war. When vicious murder, illegal immigration and the importation of underage girls for prostitution are added to the mix, Bruno has his work cut out.

Martin Walker spins an intriguing mystery leavened with charm and humour, informed by love and knowledge for France, past and present. It is a combination that will win him many devoted readers.
