After the perilous circumstances in which the newly married Julia and Philip met, it is no wonder that the Colonel wants his pregnant wife safe and away from too much excitement. Unfortunately, the remote French mountain village he chooses is not only impractical, isolated, and far from medical assistance, but is unfortunately also in the path of smugglers and saboteurs.

Collin Munro – Julia's cousin and agent for the British Secret Service – arrives on the scene to investigate a threat to the local gasworks, but it is soon clear that once again, it will be down to Julia to solve the mystery, even if she is heavily pregnant.

Emergency in the Pyrenees, book five of the Julia Probyn Mysteries, is rich with intrigue, peril, and humour.
