Murder in Auvergne

A woman's body is found near Lake Pavin in the Auvergne region. The staging of the murder baffles the investigators in its resemblance to the legend of the lake, whereby the sinners of Besse, having provoked God's anger, were buried alive and then covered in the Devil's tears. Could it be that the victim herself was considered a sinner by her murderer? For Lieutenant Bruno Romagnat, working alongside Chief-officer Aurelie Lefaivre, the case couldn't be more sensitive: it so happens that he knew the victim.
