Crime dans l'Hérault

The boss of a fashionable Cap d’Agde nightclub is found murdered in her own office. Deputy public prosecutor Elisabeth Richard and gendarme captain Charles Jouanic get back together to investigate what looks like a crime with an obvious motive, since the safe has been emptied of its money.
But then there’s another, more puzzling murder: a campsite manager is found dead wearing a fox mask. An obvious lead is a man with whom the victim had some issues, who also happens to be the former husband of the first victim.
But as it becomes apparent that they’re on the wrong track, there’s a third murder, a tourist guide this time, wearing a wolf mask.
