El club de los primogénitos

The Firstborn Club, a group similar to Alcoholics Anonymous, accepts anyone who has suffered a kidnapping at some point in their life. These are people deeply scarred by their trauma, prone to extreme behavior, who try to help each other without revealing their identities—they have all adopted the names of writers beginning with "B": Brontë, Baudelaire, Bazán… Beatriz Bernal, one of them, reports the kidnapping of her daughter by her mother, a kind of 21st-century healer, a woman who has dedicated her life to curing the evil eye. To find her, Beatriz turns to Navacerrada, something of an investigator used by the most disadvantaged classes when they are victims of harassment, robbery, or any other situation for which they would need a lawyer or detective they cannot afford. Navacerrada, a former police officer, social worker, and ex-convict, earns a living through these services, but must supplement his income with odd jobs to survive.
