France's favourite country cop, Bruno, faces a dangerous threat to the town he polices and the people he protects. Loved by millions, the Dordogne Mysteries are the perfect combination of mystery and escapism.

The event of the Perigord tourist season is to be the re-enactment of the liberation of the historic town of Sarlat from the English in 1370. But it all goes wrong when the man playing the part of the French general is almost killed in the heat of the action.

The immediate question for chief of police Bruno Courreges is was this an accident - or deliberate? The stakes rise when Bruno learns that the man, Kerquelin, was running Frenchelon, the secret French electronic intelligence base nearby, after being recruited from a brilliant Silicon Valley career. His old Silicon Valley colleagues have been invited to stay at the luxurious local chateau of Rouffillac as his guests to enjoy the Sarlat show.

As he investigates, Bruno discovers that Kerquelin's wound was faked, that he is alive and well and secretly negotiating a massive deal to build a semi-conductor industry in France. But then a whole new and dangerous player emerges, determined to nip the deal in the bud.
