In the small town of St Denis, Bruno, can't get a moment's rest. Some rare bank notes have come to light that may have links to the legendary Neuvic train robbery in 1944. The investigation is fraught with issues. Bruno is also dealing with a wave of local burglaries, which have brought his old flame, Isabelle - and their complicated history - back to the town.

Life in south-west rural France is not the sleepy idyll you might suppose. Local duck and goose farms are being attacked by animal rights protestors attempting to halt the production of foie gras. A senior policeman has been shot by terrorists believed to be the Basque Separatists of ETA. And if that weren’t enough, a group of students have just unearthed a ‘modern’ skeleton during a dig at one of the ancient sites of this famous region and home to prehistoric man - a dig that has brought an influx of foreigners to the Dordogne.

Bruno, Chief of Police in the charming French town of St Denis, is already busy with a case when the body of an undercover French Muslim cop is found in the woods, a man who called Bruno for help only hours earlier. But Bruno's sometime boss and rival, the Brigadier, doesn't see this investigation as a priority - there are bigger issues at stake. Bruno has other ideas. Meanwhile, a Muslim youth named Sami turns up at a French army base in Afghanistan hoping to get home to St Denis. One of Bruno's old army comrades helps to smuggle Sami back to France, but the FBI aren't far behind. 

St Denis may be picturesque and sleepy, but it has more than its fair share of murder and mystery, as Bruno knows all too well. When Bruno is invited to the 90th birthday of a powerful local patriarch - a war hero with high-level political connections in France, Russia and Israel - he encounters a family with more secrets than even he had imagined. 

Just before dawn one late-summer morning, Captain Bruno Courrèges is roused from sleep by the wail of the town siren atop the Mairie, summoning the volunteer firemen of St Denis. Bruno, the only policeman in the small Périgord town, follows the fire engines towards the site of a large barn, now engulfed in flames, the surrounding fields ablaze. Everything points to arson. A Californian wine maker is planning to buy up half the valley to create a huge wine-producing operation.

Best-selling author Martin Walker’s previous two novels starring Chief of Police Bruno Courrèges became hits with fans and critics around the globe. In this thrilling third mystery, Bruno has his hands full with trouble in the truffle trade in St. Denis’ marketplace. And when a friend is murdered, things really start heating up.

Following the funeral of a local farmer, Bruno gets a phone call from his son. He tells Bruno that before his father's sudden death, he had signed over his property to an insurance company in return for a subscription to a luxury retirement home. Bruno discovers that both the retirement home and the insurance company are scams with links to a Russian oligarch whose dealings are already being tracked by the French police. 

The victim carries no identification and her fingerprints are not known to the French Police or Interpol.The only clue to the woman's identity is that her dentistry looks American, but Bruno's inquiries at local hotels and gites yield no trace of a missing foreign woman. The chateau of Commarque, begun in the 11th century, was founded by a Bishop of Sarlat and entrusted to the Knights Templar. In the rocks beneath it are caves.

Bruno, now Chief of Police for the whole Vézère valley, has an unusual challenge to rise to: teaching at his friend Pamela's new cookery school. It is a daunting prospect - the disappearance of one of the school's pupils almost serves as a welcome distraction. When the woman's body is discovered in one half of a double homicide, the evidence points to something far out of the ordinary. The other murder victim is a man, covered in combat scars and with a false passport. Investigations reveal a list of enemies as long as Bruno's arm. 

Bruno Courreges is chief of police of the lovely town of St Denis in the Dordogne. His main wish is to keep the local people safe and his town free from crime. But crime has a way of finding its way to him. For 30 years, Bruno's boss, chief of detectives Jalipeau, known as J-J, has been obsessed with his first case. It was never solved and Bruno knows that this failure continues to haunt J-J. A young male body was found in the woods near St Denis and never identified. For all these years, J-J has kept the skull as a reminder. He calls him 'Oscar'.
