Blowback (Enzo Files #5) by Peter May; 2017. Softcover

Seven years earlier, France's top chef, Marc Fraysse, summoned the world's culinary press to his remote restaurant in central France to make an announcement that he said would cause shockwaves in the culinary community. Speculating that Fraysse's restaurant was about to lose one of his precious Michelin stars, the reporters were shocked to find instead that the great chef had been murdered. In the end, the media left without a clue about the message the chef intended to deliver or about who might have killed him.

Continuing his string of investigations into stubborn cold cases, ex-forensics superstar Enzo Macleod takes on the case, diving into the big business and high stakes of French haute cuisine. Winter has settled in around the mountaintop restaurant, causing complications. And as he learns more about the complex web of relationships that surrounded the celebrated (if also mercurial) chef--a spurned lover, a jealous wife, an estranged brother, an embittered food critic--Macleod begins to see parallels with his own life and loves. In diving into this new case, he finds himself reopening old wounds of his own . . .
