This time, the Canarias Noir, a major crime fiction festival, is about to open its doors when a corpse appears on display inside the university that hosts the event. Luis and Naira suspect that it is a ritual crime, typical of a serial killer. However, the turbulent career of the victim, the emerging writer Camila Turino, points in many other directions: a literary critic who abused her; an editor who despised her; a sales competitor who was jealous of her talent; and a father with financial problems who will now inherit the considerable royalties from her work.

Alba and Ángel have organised a dream wedding. At least, until one of the wedding guests collapses dead during dessert. The suspects? The bride's uncles, members of the Irish mafia, the same mafia that Luis has been chasing for years from Madrid. But they are not the only ones. Naira and Luis will have to deal with two boyfriends who are in a dysfunctional relationship.
