Hermanas

May 1993. Tied to tree trunks and dressed for their first communion, Amber and Alice Oesterman are found dead on the banks of the Garonne. Thus begins the first investigation of Martin Servaz, who focuses his attention on Erik Lang, an author of crime novels with cruel and disturbing overtones, among which is one titled precisely The First Communion, and of whom the two sisters were fervent followers. The case is closed due to an unforeseen outcome, which leaves Servaz corroded by doubt. February 2018. The writer Erik Lang discovers his murdered wife, also dressed in first communion. Twenty-five years later, Martin Servaz is again immersed in that double crime and his old fears reawaken, to the point of bordering on obsession.
