The Dordogne Mysteries
A Shooting at Chateau Rock

Following the funeral of a local farmer, the man's son tells Bruno that before his father's sudden death he'd signed over his property to an insurance company in return for a subscription to a luxury retirement home. Bruno's not convinced it's a criminal matter until he discovers that the retirement home and the insurance company are scams with links to a Russian oligarch. Meanwhile, the village's adopted aging British rock star decides to sell his home, Chateau Rock.
This prompts a family reunion, with his son bringing home a new girlfriend who is Russian and whose father happens to be the oligarch Bruno is investigating.
