El asesino de la máscara Noh

An unusual case has disoriented the police of Barcelona: in the tunnel of an abandoned metro station, a body appears in conditions difficult to explain and harder to believe. The corpse has had part of its face ripped off and a mask from the traditional Noh theatre in Japan has been placed in its place.

When the police unit in charge of the case is trying to understand what has led a person to commit such a crime, a second body appears in similar conditions. Next to her, lies the documentation of the ex-girlfriend of inspector Andreu Martí, who will face the most difficult case of his career.
