Martin Walker is an interesting guy to be writing mysteries. He's the Senior Director of the Global Business Policy Council at A.T. Kearney, the management consulting firm. Membership in the Council is by invitation-only and the symposium is closed-door. Members include academic, corporate, and government thought leaders, who meet annually to discuss issues that affect the worldwide business climate.
And that's where Black Diamond, the third mystery featuring Benoit "Bruno" Courréges is set. Bruno is the police authority in the town of St. Denis, which is on the Dordogne River. There seems to be a problem in the truffle market in nearby Ste. Alvère, and Bruno is asked to investigate.
Black Diamond, which is one way to describe a good-size truffle, is an interestingly complex novel. Although it is set in contemporary rural France, the country's colonial history in French Indo-China and Algeria pokes its nasty nose into present-day affairs. And when Hercule Vendrot, Bruno's elderly friend, hunting companion, former secret agent in Vietnam and Algeria is found brutally murdered in the forest, that history has invaded Bruno's patch.
Bruno is an interesting cop. He's a gourmet cook (don't read this book if you're hungry), still plays rugby, and is former soldier who was wounded on a peacekeeping mission in the Balkans. He's had an affair with a policewoman who's moved on to bigger things in Paris, and he has a relationship with an English woman who lives in St. Denis. He never carries his official pistol and "has long since lost the key to his handcuffs," but he also has good relations with the larger police organizations and knows the neighborhood and the people.
Given Walker's background, the book feels unusually rich. We learn not only about truffles—how they are found, graded, and marketed—but France's current challenge of illegal Chinese immigrants, friction between the Chinese and Vietnamese, and—not the least—what ordinary life in a French town is usually like.
Black Diamond satisfies my three criteria for a decent mystery: an engaging protagonist/detective, a convincing setting, and a plausible murderer. I'm going back to the first two Bruno mysteries in the series.
