In Tandem

In troubled waters (6x10)

:

Gunshots ring out on the edge of the Méjean pond, and a nature defender is found dead. The murderer is not far away, we must act quickly. The gendarmes understood that the victim had been plotting to investigate around the pond. Léa is convinced that she was looking for something in the pond, but what? It sends divers who pull out a second body. Who is this second victim who has apparently not been declared missing? What is the connection between the two victims? Were they killed by the same person?
