A song for drowned souls

Marsac is a quiet town in the Pyrenees, best known for its elite university. But when one of its professors is murdered, it becomes clear that the tranquil surface is a lie. The chief suspect is the son of Commandant Servaz's university sweetheart; and when she implores him to investigate, he cannot refuse. To close the case, Servaz must delve into his own past and re-open old and terrible wounds. It will be his most dangerous - and his most personal - investigation yet.
