Mort blanche

A young woman comes down from a hiking trail, she tries to call for help and collapses. Cause of death: forced injection of heroin. Why was this young student, healthy and sporty, killed in the middle of the mountains? Settling of scores? Warning? For whom? Faced with the indignation of the inhabitants of a working-class district of Annecy, Cassandre will have to fight. How much longer will dealers kill their children without them reacting? Cheered up, Cassandre is not at the end of her surprises: what is Yvan, her ex from 36, doing in Annecy? It's a game of cat and mouse that Cassandra and her team will have to win... And very clever who thought he would take.
