Captain Bruno Courreges goes by the grand title of Chief of Police, though in truth he's the only municipal policeman on staff in the small town of St Denis in the beautiful Perigord region of south west France. When an old man, head of an immigrant North African family, is found murdered, suspicion falls on the son of the local doctor, found in flagrante playing sex games surrounded by Nazi paraphernalia. But Bruno isn't convinced, and suspects this crime may have its roots in that most tortured period of recent French history - the Second World War.
